Latest Patents
Kishi's latest patents include an optical coupling device with a detecting element in the driver that provides uniform intensity of an optical signal. This innovative photocoupler features a light-emitting diode (LED) that emits light based on an input electrical signal. It also includes a driver that supplies the electrical signal to the LED, a light receiver with a photodiode, and a half mirror that alters the direction of light emitted by the LED. This design allows for the control of current supplied to the LED based on the reflected light, ensuring uniform light emission intensity.
Another notable patent is the optical coupled type isolation circuit. In this circuit, a pulse width modulation (PWM) encoder encodes a one-bit binary data signal from a sigma-delta analog-digital converter. The PWM signal, which includes narrower and wider pulses corresponding to binary codes '0' and '1', is transmitted to a decoder through a light-emitting device and an optical recovery circuit. This innovation allows for the simultaneous transmission of the clock signal and data signal in a single channel.
