Abstract: A control method improves the efficiency profile of a power supply across a wide range of output loading. The method includes obtaining a measure of output power for a power supply, which includes one or more output modules and an auxiliary power supply. The method determines whether a maximum power rating of the auxiliary power supply is sufficient to provide the measure of output power. Responsive to a determination that the maximum power rating of the auxiliary power supply is sufficient to provide the measure of output power, the controller of the power supply directs the auxiliary power supply to provide the output power.

Abstract: Channel predictive behavior and fault analysis may be provided. A forward time value may be determined comprising a time a forward signal takes to travel from a transmitter over a channel to the receiver. Next, a reflected time value may be determined comprising a time a reflected signal takes to travel to the receiver. The reflected signal may be associated with the forward signal. A discontinuity may then be determined to exist on the channel based on the forward time value and the reflected time value. The reflected signal may be caused by the discontinuity and a high impedance or low impedance at the transmitter present after the forward signal is sent.

Abstract: An apparatus comprises an Ethernet port including high-side transformers and low-side transformers. High-side current paths supply high-side currents form a high voltage rail to high-side center taps of the high-side transformers. Low-side current paths supply or do not supply low-side currents from a low voltage rail to low-side center taps of the low-side transformers, and convert the low-side currents to sense voltages. A controller configures the low-side current paths to either supply or not supply the low-side currents to the low-side center taps when none of the sense voltages exceed a voltage threshold representative of an overcurrent threshold or when at least one of the sense voltages exceeds the voltage threshold, respectively. A current monitor injects additional current into the low-side current paths only when at least one of the high-side currents exceeds the overcurrent threshold.

Abstract: A combined liquid and air cooling system is provided over a printed circuit board (PCB) of an electronic device, where the PCB includes an integrated circuit package including an application specific integrated circuit (ASIC) die and a plurality of high bandwidth memory (HBM) modules located proximate the ASIC die, and the combined liquid and air cooling system includes a liquid cooling system located over the integrated circuit package and an air cooling system integrated with the liquid cooling system and a portion of the PCB. The system operates in a normal mode, where both liquid and air cooling systems provide cooling to components of the PCB, and a fail-safe mode, where the liquid cooling system is not operating (e.g., due to a detected condition) but the air cooling system operation is adjusted such that it provides sufficient cooling to PCB components which facilitates continuous operation of the electronic device.

Abstract: In some implementations, a method includes analyzing an amount of data communicated by a set of network interfaces. The data communicated by the set of network interfaces is processed by a set of functional units and a set of queues includes the data communicated by the set of network interfaces. The method also includes activating a first functional unit of the set of functional units when a first size of a first queue of the set of queues is above a first threshold. The method further includes deactivating the first functional unit of the set of functional units when the first size of the first queue of the set of queues is below a second threshold. The method further includes causing the data to be forward to one or more active functional units via a data interconnect coupled to the set of network interfaces and the set of functional units.

Abstract: A system includes a millimeter (MM) wave radar detector, where the MM wave radar detector generates signal data associated with a person of interest (POI) within a field of view of the MM wave radar detector. The system further includes an Access Point (AP) coupled with the MM wave radar detector. The AP includes a computing device to receive and analyze the signal data provided by the MM wave radar detector to determine a movement of the POI within an environment, and facilitate generation of a feedback response in response to the determined movement or action of the POI within the environment.
