Abstract: The disclosure describes keyword detection in an audio processor and methods therefor including a low-power keyword detection engine (LKDE) and a high-power keyword detection engine (HKDE). In one implementation, the LKDE detects a keyword in data from a single audio source while buffering data from multiple audio sources and, upon detection of a keyword, the HKDE is awakened to verify the previously detected keyword by processing the buffered audio data from the multiple sources.

Abstract: A circuit coupled to a light emitting diode (LED) driver circuit is described. The circuit is operative to control functionality of the LED driver circuit based on a firing angle from a power switch.

Abstract: One embodiment in accordance with the invention can include a circuit for controlling a light emitting diode (LED) lighting fixture via a power line. The circuit can include a power switch coupled to the power line and is for outputting a firing angle. Additionally, the circuit can include a control circuit coupled to the power switch and is for implementing firing angle control of the power switch. Furthermore, the circuit can include a translator coupled to receive the firing angle and for mapping the firing angle to a function of the LED lighting fixture.
