For the first time in North America, AutoSens and InCabin USA co-located at the Huntington Place in downtown Detroit during the week of May 20th, 2024. The event featured an extensive agenda across two tracks, expert-led roundtables, in-depth tutorials, and a full exhibition floor of the latest ADAS innovations that are shaping the future of automotive technology.
On Wednesday, May 22nd, a press briefing was held for both conferences. Six companies made announcements as part of the InCabin press briefing, while eight companies made announcements as part of the AutoSens press briefing. Here is a recap of what each company presented during AutoSens USA 2024.
Claytex
During the AutoSens press conference, Claytex provided an overview of the Sim4CAMSens project, which aims to develop a sensor evaluation framework that spans modeling, simulation, and physical testing. Funded by the UK’s Centre for Connected and Autonomous Vehicles (CCAV) as part of its Commercialising CAM Supply Chain Competition, the project involves the creation of new sensor models, new material models, and new test methods to allow ADAS and sensor developers to accelerate their work.
Claytex leads the Sim4CAMSens project with support from a consortium of industry partners, including rFpro, Syselek, Oxford RF, WMG, National Physical Laboratory, Compound Semiconductor Applications Catapult, and AESIN.
“The Sim4CAMSens project addresses a pivotal gap in the journey towards autonomous vehicles. The perception sensors are the eyes of these vehicles, and ensuring their accurate representation in simulations is critical,” said Mike Dempsey, Managing Director of Claytex, a TECHNIA Company. “This collaboration of industry leaders will contribute to safer and more reliable autonomous mobility.”
As outlined by the Sim4CAMSens official website, key objectives include:
- Quantify and simulate perception sensors in all conditions. Doing so enables sensor suppliers to more fully demonstrate their solutions.
- Enhance synthetic training data by improving perception sensor models.
- Proposing a credible simulation framework and ensure that AVs are safe to deploy to the satisfaction of regulators.
- Development of improved noise models. This involves both laboratory and field tests to identify and quantify the noise factors that impact sensor performance.

These nanostructures are composed of polymers with unique properties to minimize reflection and maximize transmittance.
“Depending on customer requirements, the nanostructures can be deposited on flexible substrate in R2R process with high uniformity and scalability or directly deposited on a rigid free-shape surface with high resolution and precision,” Dexerials said in a statement.
At AutoSens USA 2024, Dexerials’ team offered optical solutions including:
- Ghost image reduction.
- Anti-fogging and seamless designs.
- How a nanostructured surface mitigates optical noise and empowers sensing technologies.

Soudakova and Hanashima san discussed the company’s expansion into the photonics business and potential partnerships in the space.
Sheba Microsystems Inc.
Sheba Microsystems shed light on its recently launched vehicle camera, Sharp-7. It is the world’s first autofocus automotive-grade camera that incorporates an eight-megapixel sensor and an integrated MEMS driver to generate high-quality imaging across all automotive temperature ranges, ultimately improving the safety of vehicles with the latest ADAS systems.
“Over the past two decades, we all have seen how high-resolution sensors have dramatically improved cameras on our phones,” said Dr. Faez Ba-Tis, CEO and co-founder of Sheba Microsystems. “A key enabler for such high-resolution imaging was the adoption of autofocus actuators.”
During the press event at AutoSens USA 2024, Sheba shared more about its patented MEMS technology, including:
- Thermal stability and consistent performance at temperatures ranging from -40 to 150 degrees Celsius.
- Precise imaging during thermal and mechanical shocks, thermal cycling, vibration, tumble, and microdrop tests.
“But the absence of reliable autofocus actuator technology that can operate in the automotive environment, coupled with the problem of thermal expansion, has been a decades-long blocker and has limited the adoption of high-resolution sensors in automotive cameras,” Dr. Ba-Tis added. “With the Sharp-7 camera, we wanted to demonstrate not only how Sheba MEMS technology solves for thermal expansion and produces consistent, high-quality imaging from existing eight-megapixel sensors, but also how our technology paves the road towards the adoption of even higher resolution image sensors, which will ultimately keep everyone on the road safer, especially with today’s advancements in autonomous vehicle technology.”

neurocat
neurocat announced a collaboration with Taiwan-based oToBrite to advance its Vision-AI solution even under the most adverse weather conditions. This collaboration will utilize neurocat’s image augmentation technology to enhance the performance of oToBrite’s Vision-AI solution, resulting in:
- Vulnerable road user detection (i.e., cyclists and pedestrians).
- In-context detection (i.e., lane departure, wrong-way, and forward collision warnings).
As explained by the companies at AutoSens USA 2024, autonomous driving constitutes a high usage of algorithms and data, and data collection is a complex task with respect to expenditures and weather uncertainty.
“With its collaboration with neurocat, oToBrite is on the forefront of finding solutions to these data challenges. neurocat’s image augmentations offer a way to quickly generate highly targeted data that precisely fills data gaps that are directly related to the needs of model development,” the companies said in a joint statement. “Leveraging the new augmented data for retraining represents a promising road to ensure oToBrite continues to be a leader in safe autonomous driving systems.”
