Abstract: A voltage sensor system for determining an abnormal circuit condition in a multi-layer printed circuit board is disclosed. The printed circuit board has a plurality of layers. One of the layers includes a trace network and a sensor circuit. The sensor circuit includes the trace network and a sensing point. The sensor circuit is coupled between a voltage supply and a ground. A controller is coupled to the sensing point. The controller is operable to determine a voltage of the sensing point and compare the voltage to a threshold value to determine an abnormal circuit condition in the printed circuit board.

Abstract: A computing system includes a cabinet, an inlet temperature sensor, a cooling device, an environmental sensor, and at least one processor. The cabinet houses at least one computing device. The inlet temperature sensor is configured to detect inlet temperature data for the at least one computing device. The inlet temperature data represents internal temperature within the cabinet. The cooling device is coupled to the cabinet for maintaining temperature within the cabinet. The environmental sensor is configured to detect environmental temperature data external to the cabinet. The environmental temperature data represents external temperature outside the cabinet. The at least one processor is configured to: (a) determine if one or more of the inlet temperature data and the environmental temperature data exceeds a temperature range; and (b) in response to the temperature range being exceeded, generate a first warning signal indicating a temperature problem.
