System and method for multiple sense point voltage regulation
First Claim
Patent Images
1. A system for sensing the voltage at multiple sense points comprising:
- one or more connectors for receiving adapters or other electronic components;
sensors, connected to each of the connectors, for sensing the voltage used and needed by the connectors;
a multiplexer (MUX) for receiving voltage readings from the sensors and for multiplexing those readings and passing those readings to a logic system;
the logic system determining a highest voltage and a lowest voltage of the voltage readings and for selecting which of the highest voltage and the lowest voltage readings is closest to a voltage requirement; and
a voltage regulator, connected to the logic system, for receiving the closest voltage reading.

Abstract
The present invention is a system and method for sensing the voltage at multiple sense points. The present invention acquires optimal feedback from a plurality of sources including those integrated on the same motherboard, for populated or unpopulated connectors and for adapter cards plugged into the connectors, for the purpose of controlling the voltage regulator output. The voltage regulator, connected to a logic system, provides voltage to those connectors needing the voltage.
