International Classification:

H02H 3/04
H02H 3/20
G08B 21/00

US Classification:

340662, 361 911

Abstract:

Methods and systems for sensing overvoltage in an electrical circuit are provided. In one implementation, an overvoltage sensor is provided that includes a first connector operable to be connected to a second connector of a provided electrical circuit, in which the second connector includes a first lead connected to a first voltage in the provided electrical circuit. The overvoltage sensor further includes an indicator circuit coupled to the first connector, in which the indicator circuit is operable to sense overvoltage of the first voltage responsive to the first connector being connected to the second connector.

International Classification:

G06F 13/00

US Classification:

710104

Abstract:

A design structure embodied in a machine readable storage medium for of designing, manufacturing, and/or testing a design is provided. The design structure includes an apparatus for setting a reference voltage for a bus agent. The apparatus includes a computer processor, a computer memory, with computer program instructions disposed within it, operatively coupled to the computer processor. The computer program instructions are capable of identifying a present configuration of a bus, and identifying a reference voltage value for each bus agent connected to the bus. The apparatus further includes means for applying a reference voltage to each bus agent in dependence upon an identified reference voltage value for each bus agent.
