Light emitting/receiving module
P8212 is a light emitting/receiving module consisting of an LED array and a photodiode in the same small package. The width of this module is minimized so that automobile antennas can be designed thin. A lens is also fitted onto the photodiode to increase the amount of input light. Although the lens makes the photodiode directivity narrow, this problem was solved by separating the photodiode optical axis from the LED axis to match the light emitting and receiving areas required for VICS.

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
