In one or more embodiments, a PSU comprises a bridgeless PFC circuit with a hold-up time extension. If a voltage drop is detected, a relay switches operation to a first boost converter action to store energy in a PFC choke. If voltage remains low, the PFC choke may transfer energy to a bulk capacitor, increasing the amount of time an information handling system can operate before a shut-down procedure needs to start. If power returns, selected switches are turned on in an order such that an inrush current does not damage components in the PSU.

Disclosed is a method, performed by an electronic device, for handling shipment of a container. The method includes obtaining historical data associated with container shipment.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control signaling indicating a cell discontinuous reception (DRX) cycle for a cell for communicating with the UE. In some examples, a cell DRX cycle may alternate between an active duration during which a cell may monitor communications and an inactive duration during which a cell may refrain from monitoring communications. In some examples, a UE may send a request to extend an activity duration of a cell DRX cycle during one or more cycles of the cell DRX cycle based on a performance parameter associated with an uplink transmission satisfying a threshold. Thus, the UE may transmit an uplink transmission during an active duration of a cycle that is extended based on the transmission request.

The present invention aims to, in a case where measurement data affected by a body movement that occurred during an examination is re-measured, reduce a time extension caused by the re-measurement.Whether or not re-measurement is necessary is determined in consideration of continuity of measurement data affected by a body movement. In addition, in a case of performing the re-measurement, measurement of a part of unmeasured measurement data is omitted in consideration of a measurement time (number of phase encoding steps) of the measurement data to be re-measured.

The embodiment of the invention provides a plug-in extension method, a plug-in extension system and related equipment, which are used for dynamically adding extension plug-ins and realizing real-time extension of functions. The method provided by the embodiment of the invention comprises the following steps: defining a plug-in extension interface of any function extension item in a to-be-extended system function; defining a plug-in container interface of the system function so as to manage any function extension item in the plug-in container through the plug-in container interface; defining a registrar interface of the system function, and obtaining a plug-in container instance of the registrar interface in the plug-in container; the plug-in container is registered to the register through the plug-in container instance, and the incidence relation between the plug-in container and the function extension plug-in in any function extension item is managed through the plug-in attribute information of the function extension item, so that in the extension process of any function extension item, the function extension plug-in in any function extension item can be stored in the register. And registering the function extension plug-in to which any function extension item belongs to the corresponding plug-in container through the register to realize the extension of the system function.

In an embodiment, the UE determines a maximum duration that the UE should remain active after a DRX ON period to transmit or / and process one or more reference signals for positioning associated with a positioning session. The UE transmits an indication of the maximum value to the BS. The UE and the BS each selectively transmit and / or process the one or more reference signals (e.g., DL PRS and / or UL SRS-P) based at least in part on the maximum duration.

A power supply unit comprises holdup circuitry and a controller. The holdup circuitry comprises a supply line, a ground line, a first holdup capacitor, a second holdup capacitor, and switching circuitry. The switching circuitry switches the holdup circuitry between a first configuration in which the first holdup capacitor and second holdup capacitor are coupled in parallel between the supply line and the ground line and a second configuration in which the first holdup capacitor and second holdup capacitor are coupled in series between the supply line and the ground line. The controller is configured to detect that an output voltage of the holdup circuitry has dropped to a threshold voltage and, in response, control the switching circuitry to cause the holdup circuitry to change from the first configuration to the second configuration.
