Abstract: A method includes energizing a transformer from a deenergized state by turning on a solid-state transfer switch to conductively couple a power source on a first side of the solid-state transfer switch and a transformer on a second side of the solid-state transfer switch, and evaluating an inrush current to the transformer from the power source. The method includes turning off the solid-state transfer switch to conductively decouple the power source and the transformer in response to the inrush current meeting a first criterion, determining a recoupling timing for the solid-state transfer switch, and turning on the solid-state transfer switch in response to the recoupling timing effective to complete energization of the transformer with the inrush current to the transformer being limited by the first criterion.

Abstract: This disclosure describes, in part, techniques for determining a latency associated with a network application. For instance, an electronic device may receive first data from a first sensor, where the first data indicates that a control device received an input. The electronic device may also receive second data from a second sensor, where the second data indicates a change in content being output by a display device. The electronic device may then determine a first time associated with the control device receiving the input and a second time associated with the display device outputting the change in content. Additionally, the electronic device may determine the latency using the first time and the second time. The electronic device may then provide the latency to a user.

Abstract: One embodiment facilitates measurement of a performance of a storage device. During operation, the system determines a normalized cost for an I/O request, wherein the normalized cost is independent of an access pattern and a type of the I/O request, wherein the normalized cost is indicated by a first number of virtual I/O operations consumed by the I/O request, and wherein a virtual I/O operation is used as a logical unit of cost associated with physical I/O operations. The system identifies a performance metric for the storage device by calculating a second number of virtual I/O operations per second which can be executed by the storage device. The system allocates incoming I/O requests to the storage device based on the performance metric, e.g., to satisfy a Quality of Service requirement, thereby causing an enhanced measurement of the performance of the storage device.

Abstract: An apparatus and method that can accelerate the turn off time for a thyristor current interrupter. Following commutation of a load current from a main thyristor to an auxiliary turn-off unit, a capacitor of the auxiliary turn-off unit can provide a resonant current to create a zero current crossing for turning the main thyristor off, as well as provide a reverse bias voltage for the main thyristor. The auxiliary turn-off unit can hold the main thyristor off and facilitate sufficient time being available for main thyristor to block forward system voltage. A voltage level of another capacitor of the auxiliary turn-off unit can, with a switch of the auxiliary turn-off unit and the main thyristor turned off, be increased to a level that triggers at least one voltage-clamping unit to absorb electrical power from that capacitor.
