Latest Patents

Igarashi holds a patent for a "Signal transmission system and method." This data transmission system includes a data carrier with a memory for storing data, including an identification code. The data carrier is attached to an object and communicates with a main apparatus that has a microwave oscillator. This system allows for the writing and reading of data from the memory of the data carrier using microwave signals. The main apparatus transmits a microwave modulated by a command or data, followed by a nonmodulated carrier for a predetermined period. Upon receiving a command, the data carrier executes a read/write operation and generates a response. The data carrier then modulates the received nonmodulated carrier using response data, reflecting the modulated carrier with a shifted plane of polarization.
