As airbags are one-time use only and have to be replaced in the garage after deployment, this system also helps to save money. It avoids unnecessary airbag deployment, for example, in seats where there are no passengers and therefore avoids the need to replace them.
Besides airbags, occupant detection and monitoring is also necessary for other advanced driver assistance systems (ADAS). Some cars, for example, use seat-belt tightening as a pre-crash safety measure in the case of an accident, which requires occupant information. In addition, fatigue detection can be performed by monitoring eye movements and blinking frequency using a camera. Monitoring the driver’s activity becomes an important topic when considering the future direction to automated driving, as the driver will be allowed to do other things besides the actual driving task, such as reading or working with a tablet. It is therefore crucial that the take over time from automated driving mode to manual driving will be short enough, in case of an emergency situation, if the system is not completely autonomous.
Our TOF CMOS sensor works with an indirect time of flight (TOF) measurement as a 3D sensor. It can therefore deliver the information about the occupants’ position or about the driver’s activity or fatigue. An infrared laser diode or LED, or an array of these, is used as active illumination and sends out short light pulses. The CMOS sensor determines the time of flight of the reflected, incident light with each of its pixels, creating a 3D picture. This CMOS sensor is a special, high-speed charge transfer device, which is essential to measure short distances. The light pulse travels with a high speed of 3*108 m/s to the object and back. The closer the object, the shorter is the time of flight. Therefore the detector must be able to do the whole measurement within several nanoseconds.

The company was founded in 1953 by Heihachiro Horiuchi, a former student of Kenjiro Takayanagi, who is known as 'the father of Japanese television'.[4]
Hermann Simon, a leading German business author and thinker, mentioned Hamamatsu in his book titled Hidden Champions of the Twenty-First Century: The Success Strategies of Unknown World Market Leaders as an example of a 'Hidden Champion'.[2]
Hamamatsu CCD image sensors are used at the Subaru Telescope of the National Astronomical Observatory of Japan.[5]
Hamamatsu Photonics' photomultiplier tubes (PMTs) were used in the Super-Kamiokandeneutrino detector facility at the University of Tokyo where 2015 Nobel Prize Laureate Takaaki Kajita conducted his research. In using products contributed by Hamamatsu Photonics, 'Kajita was able to prove that neutrinos do in fact have mass -- a major shift in our fundamental understanding of how the universe works,' said Tom Baer, chair of the Photonics Industry Neuroscience Group of the National Photonics Initiative. 'This win is a tremendous accomplishment for Kajita and Hamamatsu Photonics.'[6]
Hamamatsu Photonics Infrared
The sensors made by the company also helped confirm the existence of the Higgs boson in research that led to the 2013 Nobel Physics prize.[7]
In March 2020, Hamamatsu Photonics established a subsidiary, Hamamatsu Photonics Korea Co,. Ltd, to increase sales in the Asian region.[8][9]
