Abstract: Optical systems can emit train(s) of light pulses onto objects to derive a distance between the light source and the object. Achieving meter or centimeter resolution may require very short light pulses. It is not trivial to design a circuit that can generate narrow current pulses for driving a diode that emits the light pulses. An improved driver circuit has a pre-charge path comprising one or more inductive elements and a fire path comprising the diode. Switches in the driver circuit are controlled with predefined states during different intervals to pre-charge current in the one or more inductive elements prior to flowing current through the fire path to pulse the diode.

Abstract: A system is provided for updated processing of audio signals in a vehicle. The system includes a microphone, a transceiver and head unit. The microphone receives audio signals. The transceiver sends the received audio signals to a cloud computing system for processing, and receives the processed audio signals from the cloud computing system. The head unit receives the processed audio signals from the transceiver and plays the processed audio data through the vehicle's audio system.
