Latest Patents

Kee Eng Soo holds a patent for a "Circuit to prevent acoustic feedback for a cellular speakerphone." This invention addresses the common issue of audio feedback between electronic devices and audio accessories. The circuit includes a current limiting device that is coupled serially in the receive (Rx) line. It is actuated via a delay circuit connected between the current limiting device and the transmit (Tx) line. When a bias current is presented to the Tx line, it propagates through the delay circuit, actuating the current limiting device after a predetermined time. This design ensures that the Rx line remains open long enough for the phone to deactivate its internal microphone, effectively preventing feedback.
