Bitsensing, a South Korean imaging radar technology startup, has announced that it has designed a safety monitoring solution that can detect in-car passenger presence and location, and send alerts if there are any abnormalities. The 60GHz single radar solution MOD620 can also detect in real-time the presence of a child left in a car, even when the car is shut down and locked.

According to research, the reason for 54% of child death in hot cars since the 1990s was because they were forgotten by their caregivers. “The MOD620 prevents such casualties by efficiently detecting the presence and vital signs including heartbeat and respiration rate of occupants and sending the driver alerts if a child is left unattended inside a car,” a company press release said, adding that the solution has been built on Infineon Technologies chipset.

The Driver Monitor System (DMS) radar sensor also recognizes gestures of the driver to detect drowsiness and can send distraction warnings or offer post-crash monitoring. The MOD620 can also be used to identify if passengers are left unattended in emergencies such as car crashes.

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 electromagnetic 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 company stated.

Limitless detection, customizable antenna design

The in-cabin sensing radar captures all rear-seat space maintaining the top quality for in-cabin solutions. The 120-degree field of view combined with the customizable detection range up to 2.5 meters provides an increased level of performance. The company claims that it has also addressed the privacy concerns as MOD620 does not rely on cameras for presence detection. Besides, the rearrangeable antenna in the MOD620 allows customization in channel length compensation, the field of view, and matching circuits for transmitters and receivers.

“Bitsensing’s unique expertise in customizable antenna design allows for a quick and efficient process in matching specific in-cabin requirements for any vehicle. The MOD620 is a customizable and cost-efficient radar that works in high-speed cars, day or night, with no interference to seatbelts.”

The company also stated that its in-house specialists partnered with various labs from top universities to obtain the most accurate data to produce this radar that can accurately detect. The MOD620 offers a safety monitoring solution that is necessary for the optimal autonomous driving experience.
