Abstract: Presented herein is an air vent including a plate, and a non-uniform array of openings extending through a thickness of the plate. The non-uniform array of openings arranged to admit a flow of cooling air through the plate. The plate and the non-uniform array of openings are arranged to attenuate electromagnetic interference (EMI) emitted through the plate.

Abstract: Regulation of a voltage gradient may be provided. A plurality of test voltage values associated with a corresponding plurality of locations associated with an electronic device may be received. Then, based on the plurality of test voltage values, a target setpoint may be determined for a power supply that supplies power to the electronic device. The target setpoint may be configured to cause a maximum of voltage values at the plurality of locations to be below a maximum voltage level defined by a specification for the electronic device. The target setpoint may also be configured to cause a minimum of the voltage values at the plurality of locations to be above a minimum voltage level defined by the specification for the electronic device. The power supply may then be driven at the target setpoint.

Abstract: Presented herein are techniques in which a software-controlled load is embedded at an output of a point of load (POL) in parallel to a load that receives power from the POL. A small incremental load is applied to the POL using the software-controlled load. A transient response of the POL to the applied small incremental load is measured using an embedded analysis functionality.
