Country star Megan Moroney’s varied tour environments required a system that was reliable in all conditions, including weather-sensitive locations. From Rodeos to Outdoor Arenas: The LED System That Handles it All Country star Megan Moroney’s varied tour environments required a system that was reliable in all conditions, including weather-sensitive locations. Edited by Terry Persun Stage Events Jun 16, 2026 Megan Moroney steps onto stages across the country with a sound that has quickly become a fixture in modern country music. Gained attention with her single “Tennessee Orange” following her debut EP Pistol Made of Roses , Moroney released her first album, Lucky , in 2023 and followed it with Am I Okay? in 2024—which debuted in the top 10 of the Billboard 200. Moroney’s tour has taken her team across a wide mix of venues, from rodeos and music festivals to arenas and outdoor stages. For OSA International, Inc., the variety demanded an LED system that could withstand shifting environments, tight schedules, and repeated transport. Those requirements were met using Absen’s X5, a legacy product that still performs like new, citing its durability, serviceability, and performance consistency across more than 60 shows. Matt Searle, video director for OSA International, said the X5 tiles performed reliably in all conditions, including weather-sensitive locations such as Red Rocks. “You can put a lot of weight on the tiles, and you can easily swap one without taking the whole videoscope down,” he said. Searle noted that the design cut load-in and load-out time and limited downtime during travel. The system’s stability played a direct role in show execution. “It made it good for me directing the show, knowing everything was safe and performing the way it should.” Because Absen offered a knowledgeable local technical team that responded quickly, “It felt good going across the country and to other countries knowing they were a phone call away.” That rapid response emphasized Absen’s commitment to long-term product reliability through ongoing support, which is a core element of the company’s engineering philosophy. Images courtesy of Absen. Timmy Abercrombie, production manager for Megan Moroney, emphasized the X5 system’s adaptability for both indoor and outdoor use. The heavier tile construction allowed the crew to secure the walls in windy conditions and maintain fast build times. Abercrombie cited a quick technical resolution earlier in the year when an issue arose. “Absen took over one of the tiles and the computer,” he said. “Within 10 minutes, they had it fixed. Everything was up and running, and we were ready for the show that night.” He noted that the collaborative relationship between OSA International and Absen helped keep the tour on schedule, describing the partnership as aligned around shared tour-wide goals. Niel Niu, mechanical design engineer for Absen Inc., said, “We are not only an LED manufacturing company; we are a full solution support partner.” Niu highlighted that the X5’s durability and service-friendly design reflect the same engineering principles Absen applies across its product portfolio, contributing to the product line’s lasting performance in the field. Images courtesy of Absen. For OSA International, the combination of rugged hardware and responsive assistance helped maintain consistent visuals throughout a demanding tour. With the X5 system in place, the team delivered stable performance across diverse venues, weather conditions, and tight travel windows. Absen’s X5 is a 5.2mm LED display designed for outdoor rental applications, including concerts, live shows and festivals. The X5 supports front and rear module access, allowing module replacement in about five seconds to streamline maintenance during fast turnarounds. With brightness levels exceeding 5000 nits and a high refresh rate, the system is built for clear visibility across varied lighting conditions, but more importantly, its lasting durability spotlights Absen’s commitment to engineering products that continue performing long after they leave production.

Free-fall towers and vertical swings place extreme demands on equipment including high mechanical loads and wide temperature fluctuations. Here's how they achieve reliable and safe operation. Tower Rides at Theme Parks Require Elevated Tech Free-fall towers and vertical swings place extreme demands on equipment including high mechanical loads and wide temperature fluctuations. Here's how they achieve reliable and safe operation. Edited by EE Staff Theme Parks Jun 12, 2026 To ensure flexible designs are reliable even under adverse conditions, Conductix-Wampfler provides a wide range of modular concepts so that future expansions are easy to implement. Reliable and precise data transmission is the key to the safety and control of modern tower rides, which is why the company relies on real-time communication technologies that fit seamlessly into the attractions' designs. The optional use of customized colors enables perfect visual integration without compromising the attractions' spectacular appearance. The mobile control systems from Conductix-Wampfler guarantee safe and precise control even at high speeds and accelerations. With automated safety mechanisms and flexible motion programs, operators create an incomparable ride experience that meets the highest safety standards. Images courtesy of Conductix-Wampfler. Some of the key equipment that the company offers includes conductor rails that guarantee reliable power along linear travel paths. These rails can be bent into a ring to work with the rotating hanger on a vertical swing, enabling a 360 degree access to power and data. Even smooth winder use is possible through the use of an optional rail de-icing system. Conductix-Wampfler incorporates reliable real-time data transmission through slotted waveguide technology. Their inductive systems offer contactless, low-maintenance energy transmission and are ideal for rides that are subject to high mechanical loads due to acceleration and vibrations. To ensure that all motion sequences and effects are perfectly synchronized, the company incorporates their mobile control system. Mobile Controls Conductix-Wampfler Mobile Controls type ST-87x/ST-88x of the LJU “Series 8” control systems are compact, programmable Mobile Controls intended for driving a single motion axis. These control systems are designed for the operation and control of a defined range of motors in industrial and commercial plants. Images courtesy of Conductix-Wampfler. LJU Mobile Controls constantly evaluate the incoming commands from the system controller (e.g. via control rail) and determine the travel behavior of the transport suspension system by linking it to the current parameter setting locally implemented in the LJU Mobile Control Unit. In this way, different signals in different areas of the system can be used to achieve the desired travel behavior (e.g. slow positioning speed, high transport speed, brake release, etc.). The drive motor is driven as long as the control system detects a valid signal, and no stop command is received. External sensors connected to the control systems are monitored and evaluated independently by the control systems. If a stop command is detected, the control system brings the vehicle to a complete stop. After the stop command is cancelled, the control system starts up again according to the set delay time. Building blocks to add Functional Safety are available upon request. For functions such as manual movement of a vehicle, the control systems can be addressed by means of an infra-red hand-held remote control. Assigning parameters to the control system’s defined data records can be transferred to the control system using the MU-705 manual programming device. Data records consist of vehicle parameters, PCM configuration tables, and vehicle tables. Images courtesy of Conductix-Wampfler. The vehicle parameters and configuration switches are used to set the vehicle behavior according to the system requirements and are able to activate or deactivate individual control system functions. Various additional control system functions can be activated, deactivated, and set. Positive values from 0 to a maximum 65,535 can be set as parameter values. Configuration switches are a part of the vehicle parameters. Vehicle tables contain data, which is accessed by certain control system functions. This data is assigned to the system in which the vehicle control system is used. The vehicle tables are used to set values that affect the motion and positioning functions. In the PCM command system, different half-wave patterns are transmitted to the vehicle control system via the PCM hardware. The vehicle control system is able to recognize these commands and adjust its behavior accordingly. The PCM configuration table defines how the vehicle control system behaves with a PCM command. To decelerate a vehicle slowly, bring it to a controlled stop, and to spare the brakes, the control systems offer the option of regenerative braking. Application software and operating parameters can be transmitted to the control system via infra-red by means of the optional MU-705 manual programming device. The control systems continuously monitor the basic conditions of the vehicle and, in the event of a fault, issue a differentiated message via the integrated display and, if used, a collective fault message is sent to the higher-level system controller via the signal rail. The control systems are equipped with a display that allows easy and clear reading of the status messages or error states.

An original storyline featuring Mandalorian and Grogu on Millennium Falcon: Smugglers Run at Star Wars: Galaxy’s Edge gives guests greater control over new destinations. Mandalorian and Grogu Featured in New Update to Ride at Star Wars: Galaxy’s Edge An original storyline featuring Mandalorian and Grogu on Millennium Falcon: Smugglers Run at Star Wars: Galaxy’s Edge gives guests greater control over new destinations. Terry Persun Stage Events Jun 8, 2026 Film and TV Visitors of Star Wars: Galaxy’s Edge at Disneyland park in Anaheim, Calif. and Disney’s Hollywood Studios in Orlando, FL get to experience an all-new mission aboard Millennium Falcon: Smugglers Run. The update introduces expanded gameplay, new destinations across the galaxy and appearances from fan-favorite duo, the Mandalorian and Grogu. This debut coincides with the premiere of Lucasfilm’s new film, “Star Wars: The Mandalorian and Grogu,” highlighting Disney’s use of cutting-edge technology and the unique collaboration between creative teams. The storyline has guests teaming up with Hondo Ohnaka, who is searching for recruits to help track down two ex-Imperial officers and a pirate in exchange for any cargo collected along the way. Each decision shapes how the story unfolds with the crew choosing which destination to chase down the bounties, unlocking adventures across multiple iconic locations, including Bespin, the wreckage of the second Death Star near Endor, and the bustling city-planet Coruscant. Photo courtesy of Disney & TM Locasfilm Ltd. The updated experience also introduces new interactive elements for each crew role. Pilots, gunners and engineers continue to work together to complete their mission, with expanded responsibilities that deepen gameplay. Engineers in particular will take on a new role during the mission, including choosing the destination and calling Grogu in real time, adding a unique layer of connection and unpredictability to each flight. Photo courtesy of Disney & TM Locasfilm Ltd. “Collaborating with Lucasfilm to launch this new mission alongside the film has been incredibly exciting,” said Asa Kalama, Executive, Creative and Interactive Experiences, Walt Disney Imagineering. “This new story will transport guests into the galaxy with Mando and Grogu and every flight aboard the Millennium Falcon will feel like a one-of-a-kind adventure for each member of the crew.” Photo courtesy of Disney & TM Locasfilm Ltd. Software Integration The attraction was developed in collaboration with Industrial Light & Magic (ILM), leveraging cutting-edge technology powered by Unreal Engine 5, the same tools used in the Disney+ show, “The Mandalorian”, to create a more dynamic, responsive and immersive adventure than ever before. Unreal Engine is an open and advanced 3D creation tool. It was created to enable game developers and creators across multiple industries to easily produce real-time 3D content and experiences with greater freedom, fidelity, and flexibility. This includes industrial simulations that feel like real life. In addition to using Unreal Engine 5, Walt Disney Imagineering worked with the film’s crew to leverage and adapt digital assets for the game engine. Photo courtesy of Disney & TM Locasfilm Ltd. Originally opened in 2019, Millennium Falcon: Smugglers Run quickly set a new benchmark for immersive storytelling by placing guests at the controls of the legendary Millennium Falcon . Guests became the protagonist of their own Star Wars adventure, stepping into one of three critical crew roles, each with distinct responsibilities that directly impact the outcome of the journey. Pilots steer the Falcon through tight turns and hyperspace jumps, gunners defend against incoming threats and engineers manage onboard systems and damage control. The attraction’s dynamic gameplay system responds in real time, meaning no two missions unfold exactly the same way with successes and mistakes alike shaping the narrative, the condition of the ship, and the final score.

Gimbal suspended from crane controls the motion of Iron Man props during street fight scenes with Iron Man’s nemesis, Iron Monger Hydraulic Gimbal Aids Iron Man’s Motion Control Gimbal suspended from crane controls the motion of Iron Man props during street fight scenes with Iron Man’s nemesis, Iron Monger Parker Film and TV Jun 4, 2025 Controlling the motion of Iron Man suits and other props from the Paramount Pictures and Marvel Entertainment movie at times appears to be done with futuristic technology. But instead, the advanced motion-control technology truly responsible for moving props in the movie is actually here today and includes a hydraulic gimbal, cylinders, valves, hose, fittings, and other hydraulic products from Parker-Hannifin (Mayfield Heights, OH). Stan Winston Studios built the large and sometime difficult-to-move Iron Man suits. “The Iron Monger suit is 10 feet tall and weighs approximately 800 pounds,” says Shane Mahan from Stan Winston Studios. “We developed and built it during the course of filming and used it to help bridge the character into the digital world of ILM and John Nelson. A gimbal was also built, which allowed us to push it and mimic the actions of the big torso walking.” Mahan continues: “It takes up to five operators to operate the Iron Monger when you’re using both arms. We have had a couple of instances where we’ve been able to put both arms on and do manual puppeteering to accomplish shots as well. The Iron Monger wasn’t built as a hydraulic character, so it’s basically human muscle, a gimbal, and our stuntmen making it work.” For the gimbal, the film’s Director Jon Favreau relied on Parker’s D81FH and BD101 valves. “The crew was trained very thoroughly on the implementation of the BD101 and D81FH, so the start up and operation of the system for Iron Man went very smoothly,” notes Steve Camp from Parker-Hannifin. “Iron Man was a gimbal application; however, this gimbal was suspended from a crane.” The four-axis floating gimbal was used largely in the street fight scene with Iron Man’s nemesis Iron Monger. The gimbal used D81FH servo proportional control valves. These Parker valves are used for tilt control. They are two-stage pilot operated solenoid valves with electronic spool-position feedback and on-board integrated control electronics. Their performance is characterized by repeatability and high dynamic performance. The gimbal also relied on BD101 servo valves and valve drivers. These valves are for applications requiring high dynamics, high flow, and a defined spool positioning in case of power supply breakdowns. The DB101 has onboard electronics and a closed-loop, position-controlled pilot valve and main stage. Parker sold valves, cylinders, hose, and fittings used in the gimbal. The company also supplied accumulators, gas bottles, and D31FH EH valves along with the connectors. For more information: Parker Home Previous Facebook LinkedIn Copy link Next

Multiple rigging systems and bungie-assisted motion bring 'Puppet Master - Into Thin Air' to life through immersive, multi-axis flight choreography. Custom Aerial Rigging for Stage and Theatre Multiple rigging systems and bungie-assisted motion bring 'Puppet Master - Into Thin Air' to life through immersive, multi-axis flight choreography. Gavin “Wild” Smith, Founder of Aero Motion Australia Stage Events Aug 5, 2025 Film and TV Aero Motion Australia designs and produces custom rigging systems for aerial performance across stage, theatre, circus, and screen. With deep roots in aviation and an unrelenting pursuit of visual wonder and technical mastery, the company continues to redefine what’s possible in the air—creating elegant, mechanical solutions for complex motion. For the theatrical performance, Puppet Master - Into Thin Air , Aero Motion developed a uniquely manual rigging system design capable of supporting dynamic, three-dimensional flight on multiple planes of axis, without relying on motors or automation. The system combined an overhead catenary or dual running slacklines, diversion pulleys and compound rigging pulleys with 4:1 advantage that assisted with the lifting of the aerial artist, and bungies to create an expressive movement language suited to the show’s surreal themes. At the core of the design was an overhead catenary dual rope running span line system or slackline engineered with mechanical advantage—a rope-and-pulley method that amplifies the operator’s lifting force, allowing the artist to be flown by hand. The performer was suspended from a rolling point mounted mid-span, enabling single-plane, multi-axis flight. This setup produced a pendulum-style motion across the stage, with the performer rising from an offset floor position interacting with a ground based artist and ‘floating’ through space. All photos courtesy of Aero Motion Australia To push beyond a linear flight path, a secondary tangential rigging system was introduced. This added an orbital layer of motion by tethering to the rolling point, allowing the performer to traverse complex arcs. Coordinating both systems demanded not just technical precision but also a skilled human counterweight operator—something Aero Motion believes can be trained within circus and stunt rigging disciplines. To assist with vertical movement along the Z-axis, custom-built bungy cords connected a corset-style harness to a circular spreader bar, providing elastic lift and responsive recoil that enhanced the rigging’s mechanical rhythm. These bungy cords are hand-crafted using raw materials similar to those found in AJ Hackett-style systems, tailored specifically for aerial performance applications. The construction method is intricate, carefully calibrated to achieve the desired elasticity, rebound characteristics, and overall dynamic response required for the choreography. While highly effective in delivering a fluid and energetic performance, the bungy rubber is inherently prone to wear. As the cords stretch and recoil, the energy exerted under tension generates internal heat, which gradually degrades the rubber from the inside out. Because of this, each bungy rope has a limited operational lifespan and must be closely inspected and monitored for signs of fatigue or damage before every use. Swivels enabled the spreader bar to spin freely. As the performer’s rotational speed increased, the system exhibited a striking physical effect—gyroscopic precession. This phenomenon is the change in orientation of the rotational axis of a spinning object when an external force is applied. Rather than moving in the direction of the force, the spinning object responds 90° later in the direction of its rotation, introducing new rigging geometry and layout design challenges. Aero Motion addressed this by offsetting the rig’s secondary tangential rigging system geometry to allign this to contain the full X-Y-Z motion envelope within a 15-meter (50-foot) high studio space. “The performer’s movement became both aerial and orbital—suspended in a mechanical ballet that was entirely human-powered,” says Gavin “Wild” Smith, Aero Motion’s founder. With the full spectrum of the rigging universe engaged, Puppet Master - Into Thin Air became a rare example of immersive, live performance engineering, where rigging, choreography, and physics converged. Technical Details for Engineers & Riggers: Primary System: Overhead running span line or slackline span, with 2:1 to 4:1 mechanical advantage pulley system, no automation, operated manually. Rolling point is a dual pulley on both overhead running catenary lines that rolls along the span, Kernmantle static rope 11mm diameter is used throughout the system Flight Domain: Single-plane pendulum flight with a radial rigging system manipulating the main system. Secondary System: Tangential tether to rolling point enables X-Y movement in arc, requires human counterweight operation for control. Vertical Control: Custom elastic bungies in parallel, fitted to a bespoke circular spreader. Rotation produces gyroscopic precession. Considerations: Operator training essential. Flight path management requires anchor point offsetting and clear stage-to-roof clearance of ~15m. No load cell integration. Relies on operator feel and controlled descent/lift.

How Tolomatic accurately positioned a large and heavy camera in a very tight space. Camera Positioning System for Theme Park How Tolomatic accurately positioned a large and heavy camera in a very tight space. Terry Persun Theme Parks Jun 12, 2025 When a well-known amusement park required a digital camera positioning system for a popular attraction, they turned to Tolomatic for a solution. The major attraction required the positioning of a large and heavy, 25-pound camera to happen in a very limited space. The solution could not use a separate control cabinet or extensive cabling, yet the motion control drive components were required to maintain an overall pleasant attraction experience. In addition, maintenance free operation was highly desirable. For the final solution, the engineering team selected to use the JVL integrated servo motors integrated with the Tolomatic ERD electric cylinder actuator. JVL’s innovative motors are integrated with the drive included, providing a flexible motion control solution that can exist outside of the control cabinet. Tolomatic’s ERD series is an economical electric cylinder that is compatible with many NEMA and metric mount stepper and servo motors to create a flexible and powerful, yet cost-effective electric cylinder solution—over the use of traditional pneumatic cylinders. ERD actuators are available in three body sizes, offer force/thrust capabilities up to 500 lbf (2.2 kN), and stroke lengths up to 24 inches (610 mm). IP67 and IP69K options are available. The Tolomatic and JVL camera positioning system for the amusement park application was chosen based on its compact size, maintenance-free ball screw design, and ease of system integration. Offering a very simple setup and configuration software added to the ease of implementation. The system incorporates a closed loop positioning configuration to ensure proper positioning of the camera every time and with minimal electric components. The final application stroke length is three inches which happens within a speed of 6-8 inches per second. For the customer, Tolomatic provided an all-in-one actuation solution that also eliminated the need for additional components. The easy, clean actuator installation with minimal maintenance requirements provided an enhanced attraction aesthetic by eliminating the need for separate control enclosures.

A multi-discipline civil engineering firm mixed outside and inside lighting to open the space of this high-speed railway office redesign in Houston, Texas. How Engineering, Creativity, and Artistic Design Lit Up This Office Space A multi-discipline civil engineering firm mixed outside and inside lighting to open the space of this high-speed railway office redesign in Houston, Texas. Edited by Terry Persun Cool Stuff May 26, 2026 The two foundational principles of lighting include the qualitative (or aesthetic) aspect and the quantitative (or engineering) aspect of light. Architectural lighting is concerned with the qualitative lighting experience. The qualitative pertains to ensuring that a space has a pleasing ambience. It is the artistic interspersing of shadows and light, darkness and illumination, highlighting certain figures and form. This is where creativity truly matters. Images courtesy of Alcon Lighting. Othon Engineering is a multi-discipline civil engineering firm focusing on private and state-sponsored projects, such as a segment of California’s high-speed railway with offices located in Houston, Texas. At the very beginning of the project, “Othon’s goal was to [afford] every desk’s seat a direct view outside—a challenge proven difficult with private offices lining the perimeter of the window walls,” designer Amy Vonderau explained. Vonderau goes on to explain that Othon Engineering’s original space was a typical closed private office with full-height panel cubicles, which basically created a maze of long corridors. There was a snag in hiring new talent because of the compartmentalized work environment. By opting to design their new space with an open concept, this gave way to community areas for project teams to easily interact. Images courtesy of Alcon Lighting. As the plan took shape—the goal of direct exterior view posed a problem with ensuring that lighting levels were balanced. “The building wasn't originally designed for an open concept ceiling, so when the lay-in ceiling was removed we had to make the most sense we could of the existing elements,” Vonderau said. Vonderau decided to create the storefront eyebrow that extended from the top of the glass in the private offices into the open ceiling area, creating a shelf. Within the shelf they used the 1-inch linear light that followed the perimeter of the private offices which in return balanced the exterior natural light into the open space. This also served as a wayfinding element that leads one from the reception to the open work area, then down the corridor to the community conference room—while ensuring this light wasn’t a glare bomb but rather an ambient continuous glow. The eyebrow flowed through the space creating the perfect path to be illuminated to help balance the natural light from the exterior into the core. Images courtesy of Alcon Lighting. Ultimately, private offices were kept along the perimeter window walls but rebuilt with glass to allow the center work area a direct view of the outside from every desk. When Vonderau specified a long linear 1-inch LED tape light that needed custom lengths and continuous corners, Jason Long, from Long Term Builders, submitted Alcon Lighting’s product, which she approved. “The linear LED light strip was the main design element within this renovation,” Vonderau said. The client for this project was Othon Engineering, while the architect was Lettie Harrell of LH2 Architecture. Amy Vonderau was the designer and Jason Long of Long Term Builders was the lighting specifier.

This education center required lighting that could adjust vertically and rotate with precision, while also blending in with the aesthetics of the space. Specialized Lighting Illuminates Environmental Education Center This education center required lighting that could adjust vertically and rotate with precision, while also blending in with the aesthetics of the space. Cool Stuff Aug 18, 2025 Museums Located in an Illinois forest preserve near the convergence of three rivers that form the Illinois River, Four Rivers Environmental Education Center’s visitor center needed a variety of interior and exterior spaces, including a 2,000-gallon fish tank, to immerse visitors in the region’s natural habitat. Wight and Company, partnering for lighting and design with Bluestone and Associates, worked on the overall design and engineering for the project, led by architect Ania Szulc. Szulc was uniquely suited for the large-scale master planning and detailed work on such pedestrian-scaled spaces because of prior planning and design for parks and recreation projects, public and educational projects, and private commercial client applications. All photos courtesy of Alcon Lighting. A two-phase approach was selected for the Four Rivers Environmental Education Center, which is part of the Forest Preserve District in Will County. IL. The initial phase involved converting an underutilized classroom into office space. Phase two involved the architectural, mechanical, electrical, plumbing, and structural infrastructure desig, which was carried out to support the exhibit scope of work designed by Bluestone Associates. The main exhibit is located in the confluence wing of the interpretive center, featuring a 2,000-gallon fish tank and mussels and bird exhibits. Additionally, there is an outside bird bath with a heated pad, providing water for birds year-round. To find the best lighting option to enhance the exhibits, Wight and Company’s challenge was to find the right museum-like lighting they could that also blended with the existing architecture and aesthetics of the education center. All photos courtesy of Alcon Lighting. Overall, the project used 89 of Alcon Lighting’s multi-sized LED track light. This LED track light is stylish and durable, with an aluminum body and clear glass lens. The track head adjusts 180° vertically and rotates 358° for precise lighting control, with a color temperature switch that transitions between 3000K, 3500K and 4000K. The track light met the flexibility required for beam spread and color temperature. The track light’s simple design also blended perfectly with the aesthetics of the space.

As differentiating features of automobiles are increasingly defined by software, OEMs are transforming their development processes from hardware- and component-centric to software-centric approaches. Complete Automotive Design Through Virtual Prototyping As differentiating features of automobiles are increasingly defined by software, OEMs are transforming their development processes from hardware- and component-centric to software-centric approaches. Gunnar Braun, Technical Product Manager, Synopsys and Stewart Williams, Segment Mamagement Director, Synopsys Cool Stuff Jul 29, 2025 In the race to develop software-defined vehicles (SDVs), automotive manufacturers (OEMs) and their suppliers are facing pressure from all angles. With vehicular codebases often exceeding those of commercial aircraft, OEMs must wrangle enormous complexity while shortening developing cycles. In addition, companies must deliver frequent software updates throughout the vehicle’s lifecycle, which continually assures quality, safety, security, and reliability. Further, cost pressures are enormous. These challenges demand faster, more rigorous software development, testing, and validation. While traditional hardware-in-the-loop (HiL) testing rigs are still a mainstay for system validation, their expense, latency, and inflexibility are increasingly at odds with the agility required by today’s automotive software development practices. To enable earlier and more efficient software testing and validation, the industry is adopting cloud-based development practices and the use of virtual prototypes. Cloud-native development Automotive software is simultaneously becoming more expensive and central to a car’s identity. Infotainment, advanced driver-assistance systems (ADAS), traction control, and even powertrain management are all shaped by lines of code. The growing adoption of electric vehicles (EVs) and the push toward fully autonomous transport have further increased the role and importance of automotive software. The shift from hardware-centric to software-centric vehicles means that OEMs and suppliers must rethink their development models. The IT industry pioneered cloud-native development approaches, leading to web applications and Software-as-a-Service (SaaS) solutions that are quickly delivered and continuously updated. These approaches involve incremental development and a strong emphasis on automation. DevOps practices further bridged the gap between the software development process and its operational deployment environment. Thanks to technologies such as containerization, testing cycles are now performed and automated in a production-simulated environment. This is one of the key challenges for OEMs and suppliers adopting cloud-native methods for SDV development: The replication of the operating environment — the vehicle — when developing and testing software. While the cloud provides virtually unlimited compute and collaboration resources, physical hardware—the ultimate destination for automotive software—often lags behind in availability. Teams often wait months for electronic control units (ECUs) to be ready for initial testing and validation. If hardware revisions are required, it extends the waiting period before OEMs and their suppliers can fully test their software at scale. All photos courtesy of Synopsys. Virtual prototypes accelerate automotive software development Virtual prototypes are models of target hardware that are used for software development, testing, and validation — before the hardware is available. Referred to as electronics digital twins (eDTs), these virtual prototypes simulate the behavior of automotive compute platforms; enable continuous software testing, integration, and delivery (CI/CD); and minimize the reliance on hardware and eliminate associated delays. Virtual platforms are used throughout the embedded software industry for starting software development before hardware is available, which results in a significant time-to-market advantage. A notable example is the open-source community’s use of QEMU, an emulator that allows open-source software stacks to leverage cutting-edge Arm CPU features well before the corresponding hardware is available. But traditional emulation-based tools were never designed for the complexity of modern automotive processors, such as Arm’s Cortex-A720AE, or the runtime demands of continuous, cloud-based software development. With Synopsys’s introduction of Virtualizer Native Execution, they are addressing these limitations and enabling Arm embedded software to be executed directly on Arm server CPUs—in the cloud, with no emulation or hardware required. This means developers can run workloads at the speed of the eventual hardware, roughly 100x faster than traditional instruction set simulators, while retaining the benefits of virtual prototypes and full compatibility with the existing ecosystem of models, tools, and workflows. Here are some of the technical and operational impacts: Software teams can validate complex system-level behaviors early and often, reducing the dependency on HiL rigs during the development cycle. With architecture parity between cloud and vehicle CPU (via Arm’s instruction set), developers can use the same development tools to significantly reduce workflow complexity. Native execution on Arm-based cloud instances, such as AWS Graviton servers, enables continuous DevOps and CI/CD pipelines, with virtual prototypes providing the critical link between development and operational environments. Leveraging the SOAFEE reference architecture An essential part of this puzzle is the SOAFEE (Scalable Open Architecture for Embedded Edge) initiative. Led by Arm and other industry stakeholders, SOAFEE provides a standardized framework and reference architecture—based on the principles of modularity and orchestration—for SDV workloads. By adhering to common standards like SOAFEE, the ecosystem of automotive OEMs, suppliers, and technology leaders can increase interoperability and reduce vendor lock-in. All photos courtesy of Synopsys. At Embedded World 2025, while in collaboration with Arm, Synopsys demonstrated how virtual prototypes, SOAFEE reference architecture, and cloud-to-edge software development come together: Leveraging Synopsys Virtualizer Native Execution in an AWS cloud environment, the demonstration featured an open-source autonomous driving workload running on top of the SOAFEE edge reference stack. Executed at real-time speed, the virtual prototype was approximately 100x faster than a comparable QEMU-based simulation. The demonstration showed how virtual prototypes replicate the structure of an edge device with sufficient granularity to validate real-world functionality and software behavior, while remaining scalable and shareable across teams and geographies. While the technical underpinnings are compelling, the business value of virtual prototypes and cloud-native development is just as important. Cloud-based workflows are becoming a prerequisite for meeting time-to-market expectations in a world where vehicle features are continuously updated via over-the-air (OTA) software pushes. Synopsys’s collaboration with Arm and other SOAFEE partners is ongoing, and forthcoming advances to Virtualizer Native Execution will enable more complex scenarios and system-level parity. This includes better support for real-time behavior, safety domains, and full-vehicle E/E system integration. In the meantime, the automotive industry has a powerful foundation on which to build.

Innovative tools help to make NASCAR manufacturing of parts faster, more efficient, and of higher quality. How NASCAR's R&D Group Optimized Its Machining Processes with Next-Level Components Innovative tools help to make NASCAR manufacturing of parts faster, more efficient, and of higher quality. Edited by Terry Persun Sports Dec 1, 2025 Lead image courtesy of Depositphoto.com . NASCAR’s Research and Development (R&D) facility relies on premium innovation to create the right solutions to manufacture next-level components ensuring speed, precision and above all, safety at all stages of development. According to Bob Duvall, Managing Director of NASCAR’s Competition Partner Program, “NASCAR teams are always looking for the best in class, and Kennametal aligns perfectly with that standard.” Behind every racecar, there's a team of dedicated professionals ensuring that each component is machined to perfection. This involves using reliable tooling solutions in a prototyping environment where parts need to be designed, programmed, and manufactured within tight tolerances—and tight deadlines. Increasing Material Removal Rates Recently, NASCAR upgraded its CNC machinery to enhance its manufacturing capabilities. To fully leverage this new technology, Hank Fowler, NASCAR’s Manager of Manufacturing turned to Kennametal which has been instrumental in optimizing NASCAR’s machining processes. “Upgrading our machines has significantly sped up my cutting processes,” said Fowler. “With the addition of flood coolant and Kennametal tools, I’ve been able to increase my material removal rates as well as improve surface finishes and reduce the need for post-processing operations like deburring.” Image courtesy of Kennametal. Fowler also mentions that once he has a part number, he speaks with his rep for additional insight as to whether or not a better option may be available. Shipping tools on time is also critical for success on timely projects. For example, when Fowler was working on a manual turning job that had a .094” groove in chromoly steel, he made a simple phone call and was able to get the tool holder and inserts on time to deliver parts. This reliability is essential for NASCAR’s fast-paced manufacturing needs, where even a slight delay can impact testing and development schedules. As part of NASCAR’s R&D group, Fowler and his team handle a wide variety of tasks. Their most common machining projects include creating inspection tools for their competition group and fixturing for various types of testing within the R&D team. Recently, the team worked on an inspection tool made with 303 stainless steel which featured a tight tolerance slot. In the past, they would have been nervous about this job, but after ordering a 3/16” HARVI™ I TE, they completed the task effortlessly. Kennametal's HARVI I TE high-performance solid end mills are designed with an innovative twisted end face that allows for ultra-aggressive cutting capabilities while also promoting stability in any type of cut. It also offers a number of proprietary features such as a precision faceted eccentric relief reducing vibrations and friction for excellent cutting conditions in multiple materials, and an innovative flute design with chip gashes within the flutes to reduce cutting forces, promote tool cooling and support efficient chip evacuation. The HARVI I TE design also features asymmetrical divided flutes and a variable helix, which enables vibration dampening even at the highest feed rates. Image courtesy of Kennametal. The partnership between NASCAR and Kennametal is a perfect example of how precision tooling can be successful in high-stakes environments. With Kennametal’s reliable and versatile tools, the R&D team can meet the demanding requirements of NASCAR’s manufacturing processes.

A Swiss startup — known for its process that makes glass permeable to telecommunication frequencies — requires the right components to create their revolutionary technology. Window Glass on Public Transportation Hinders Cell Service — Until Now A Swiss startup — known for its process that makes glass permeable to telecommunication frequencies — requires the right components to create their revolutionary technology. Edited by EE Staff Cool Stuff Apr 27, 2026 As the world becomes increasingly more reliant on wireless technology in both professional and personal applications, wireless users continue to face certain unique challenges. Making calls or using data indoors can still be a hassle in many locations. This is especially true for those using public transportation like trains, where window glass greatly impacts wireless signals. While wireless signals have become stronger and more efficient in recent years, they still struggle to penetrate building materials, including insulated glass. This makes it difficult, and in some cases impossible, to get service. Everyday clear glass can reduce wireless signals by up to 4 decibels (dB), while coated glass can reduce signals by as many as 30 dB (x1000). This is especially a problem in public transportation vehicles like trains, where passengers may struggle to receive wireless signals at all. It is an issue faced by commuters worldwide, for which Swiss startup nu glass has developed a cutting-edge solution. nu glass’s revolutionary glass cutting pattern allows wireless signals to better penetrate windows. The engraving can be completed on-site without having to remove windows. Unique Glass Cutting Pattern Most glass is insulated with a thin metal layer invisible to the naked eye. nu glass uses a patented laser technology to engrave a pattern on this layer, allowing for wireless frequencies to penetrate the glass. This treatment can increase indoor signal by up to 1000 times. The etching is nearly invisible, and it has no detrimental impact on the glass, which keeps its original protective properties. nu glass uses a portable system to complete the engraving process, allowing them to visit customers on site. The system can engrave glass while it’s in place, preventing the costly and time-consuming process of removing and reinstalling individual panes of glass. The process is fast and efficient and can be applied parallel to standard maintenance, allowing for trains to keep on their schedule and return to service on time with enhanced connectivity. nu glass’s system is currently used exclusively on trains but could potentially be used on glass installed in buildings or other structures. KNF diaphragm pumps play an integral role in nu glass’s cutting process. Multiple N 838 pumps are used in suction plates, which help adhere the system to the window during the engraving process. The pumps allow for the precision process to take place with minimal vibration. The N 838 is an outstanding gas transfer pump option. It offers a maximum flow rate of 34 l/min with an ultimate vacuum down to 100 mbar (abs.). Also available are a variety of motor options, including brushless DC motors for energy efficiency. The N 838 has excellent reliability and operates oil free, preventing media contamination. KNF’s N 838 diaphragm gas pump plays a vital role in nu glass’ engraving system, holding it in place during the precision etching process. While finding the ideal pump for their system was important, nu glass wanted to make sure they were working with a partner that shared their values. A focus on quality and sustainability were key components of those values. It was also important for nu glass, which began its life at the EPFL Lausanne, to work with a local company. This made working with KNF, with multiple facilities in nearby cities and a strong presence in the community, a natural choice. KNF has locations in 24 countries and a commitment to collaborative pump design, which allows each location to serve their communities directly. * Images courtesy of KNF.
