Introducing an innovative in-cabin sensing solution

According to the ‘Heatstroke Deaths of Children in Vehicles’, Jan Null, San Jose State University, since the 1990s, 54% of children dying in hot cars was because they were forgotten by their caregivers. The MOD620 prevents this type of casualty by efficiently detecting the presence and vital signs of in-cabin occupants and sending the driver alerts if a child is left unattended inside a car. Designed by bitsensing engineers and enabled by Infineon, the MOD620 comprehensive monitoring solution matches the specific in-cabin requirements for any vehicle offering continuous and limitless detection, regardless of clothes or blankets.

"Our partnership with Infineon demonstrates the significant progress we are making towards building safer smart cities and elevating connected living by designing radar solutions for all. This is an important moment in our company's history as we have dedicated the last three years to strategically engineering advanced radar technology that can utilise existing top tier chipsets to address this need in the market," said Dr Jae-Eun Lee, CEO of bitsensing. "bitsensing is the first and only Korean startup that can deliver all aspects of auto grade radar solutions, in-house. Our world-class engineers designed the MOD620 with the Infineon Chipset to offer a new level of confidence in safety for an industry that demands excellence, reliability, and unmatched intelligence."

To build the in-cabin sensing radar, bitsensing rearranged the hardware configuration and redesigned the antenna. Powerful computing is achieved through the MCU making it possible for radar data to be signal-processed and calculated. The MMIC transmits and receives signals through electro-magnetic waves for detection while the antenna is integrated with RF energy from the radar transmission line into the propagation medium and vice versa. These components work together seamlessly for an advanced caliber of radar performance.

"The engineers of bitsensing have years of experience in optimising chipsets. Working with Infineon's state of the art radar offering, this allowed them to strategically and systematically arrange components for the MOD620's best-in-class radar performance," said How Cheen Ng, Director, Partnership Management & Digital Marketing Communication, Infineon Asia Pacific. "Leading in innovation and committing to meaningful partnerships to develop cutting-edge technologies is at the core of what we do at Infineon. This powerful partnership produced a solution that truly transcends safety and creates a better quality of life for all."  

The MOD620 reliably detects in-car passenger presence and location. It can also detect in real-time the presence of a child left in a car, even when the car is shut down and locked as well as monitor the vital signs of occupants and send an alert if there are any abnormalities. bitsensing's in-house specialists partnered with various labs from top universities to obtain the most accurate data to produce this radar that can accurately detect.

bitsensing's MOD620 captures all rear-seat space maintaining the top quality for in-cabin solutions. The 120^o field of view combined with the customisable detection range up to 2.5m provides an increased level of performance. Privacy concerns are also eliminated with the MOD620 as it does not rely on cameras for presence detection.   

The rearrangeable antenna in the MOD620 allows for customisation in channel length compensation, Field of View, and matching circuits for transmitters and receivers. bitsensing's expertise in customisable antenna design allows for a quick and efficient process in matching specific in-cabin requirements for any vehicle. The MOD620 is a customisable cost-efficient radar that works in high-speed cars, day or night, with no interference to seatbelts.
