Abstract: A computing device includes a power supply that supplies power to the computing device. The power supply includes a hardware processor that detects an electrical power disturbance in the power supply. The power supply also includes a bus that communicates an indication of the electrical power disturbance to a monitoring device. The indication includes an identifier of the power supply.

Abstract: An apparatus includes a memory and a hardware processor communicatively coupled to the memory. The hardware processor receives, from a plurality of power supplies, a plurality of indications of electrical power disturbances detected by the plurality of power supplies and determines locations of the plurality of power supplies based on the plurality of indications. The hardware processor also determines, based on the plurality of locations, an event that caused the electrical power disturbances and classifies the event based on the location of the plurality of power supplies.

Abstract: Provided is a via for use in a printed circuit board or integrated circuit having first, second, third, and fourth layers. The via includes a first path capable of transmitting a forward current from the first to the second layer and a second path capable of transmitting a return current resulting from the forward current from the third to the fourth layer to return to a source of the forward current.
