Latest Patents

Hisashi Kumagai holds a patent for an "Identification registration for a wireless transmission-reception." This invention involves a wireless transmission-reception control system where data transmitted as radio waves from multiple wireless transmitters, along with an ID code, are received by a wireless receiver. The system decodes the data at a front-end decoder. The ID code of the received data is compared with the ID code already registered in a data register to determine if a collation of the data should be made. Only the transmitted data, whose registration is confirmed, are decoded to generate an output. Each wireless transmitter has a different, fixed ID code, and the wireless receiver can switch between a mode of registering an ID code and a mode of generating an output after decoding the transmitted data.
