Appl. No.:

13/877487

Inventors:

Phillip R. Kent - Monroe WA, US

Assignee:

International Classification:

G06F 1/26

US Classification:

713310, 713340

Abstract:

An intelligent power control system and method adapted for use with a digital rack interface pod (DRIP). A switching regulator generates a set output voltage. If power is available from a USB port of an external device, such as an external server, then the system uses this power to power the DRIP. If DC power is detected as being received on a different input from an external power transformer, then the system may still continue to use the power being received from the USB port to power the DRIP. If power from the USB port of the external device is lost but power from the external transformer is present, then the system may use the power available from the external transformer to power the DRIP. If the DRIP is being powered by USB power from the external device, and no DC power is available from the external transformer, but backup power from an appliance to which the DRIP is coupled is being received on one of the DRIP's power input ports, then the DRIP may switch to backup power from the appliance if power from the USB port of the external device (e.g., server) is lost. The system thus intelligently prioritizes the use of power available from a plurality of different power sources to maintain the DRIP powered on when one or more of the power sources is lost or otherwise not available.

Abstract:

Laser light pulses of at least two different wavelengths are reflected off a scanning mirror. A first time-of-flight distance measurement circuit receives reflected light pulses of a first wavelength and determines distances. A second time-of-flight distance measurement circuit receives reflected light pulses of a second wavelength and determines distances. The timing of transmission of laser light pulses of differing wavelengths are adjusted, and the data buffering of converted return pulses are adjusted, to compensate for laser light source misalignment.
