Abstract: An exemplary walk-in refrigeration system comprises an insulated compartment. A supply plenum is disposed between a roof insulation wall and a ceiling panel. A pair of opposing wall plenums are respectively defined between a corresponding lateral insulation wall and a corresponding interface wall. Each wall plenum is in airflow communication between the supply plenum and a respective shelf refrigeration zone. A walk-in zone is disposed between the shelf refrigeration zones. The interface walls each include a plurality of flow discharge ports which direct airflow from the respective wall plenum to the respective shelf refrigeration zone. Each interface wall may comprise an array of removable and replaceable interface panels. The interface panels may each include a vent segment with one or more capture inlet ports. An actuatable metering element on the vent segment may allow a user to selectably restrict airflow through the capture inlet ports independently for each interface panel.

Abstract: This document relates to distributed teleconferencing. Some implementations can employ adaptive audio or video enhancement to address scenarios where audio enhancement can tend to remove desirable sounds. For instance, adaptive audio enhancement can involve detecting the presence of a sound, such as clapping, and modifying audio enhancement so that the sound is retained in an enhanced audio signal. Adaptive video processing can involve detecting the presence of the sound and adding a graphical identifier to a video signal that conveys the presence of that sound.

Abstract: A vehicle including an ultra-wide band (UWB) transceiver is disclosed. The UWB transceiver may be configured to operate in a first mode and a second mode. The UWB transceiver may be configured to perform phone-as-a-key (PaaK) localization in the first mode and radar sensing in the second mode. The vehicle may further include a processor configured to activate the UWB transceiver in the first mode. The processor may receive a trigger signal to switch the UWB transceiver from the first mode to the second mode. Responsive to receiving the trigger signal, the processor may cause the UWB transceiver to transmit a radar pulse signal and receive a radar response signal reflected from a target located inside the vehicle. Based on the response signal, the processor may determine a sitting area profile and an occupant presence on a sitting area, and perform sitting area adjustment.

Abstract: Systems and methods are provided for maintaining a live state of a virtual function during VM fast save and fast restore operations. A computing system performs the fast save operation, by disabling network optimizations, while maintaining allocation and assignment of a VF to a VM and maintaining a VPCI bus connection between a VF device and hardware resources of a host device. The VPCI VSP is caused to save a VF device state to a runtime repository, while VF information is also saved to the runtime repository. A VM switch saves a synthetic network adapter, while a VM synthetic network adapter is torn down. The computing system subsequently performs the fast restore operation, by initializing the VM synthetic network adapter, retrieving the VF information from the runtime repository, causing creation of a VPCI bus interface, assigning the VF device, restoring the VF device state, and resuming the synthetic network adapter.

Abstract: A heating arrangement for a cooking appliance, such as a toaster or oven. Heating elements can be exposed in a cavity of the appliance and can have a shield that permits infrared energy to pass but blocks microwaves and/or provides physical support for internal components such as a quartz tube or resistance element. The shield can be grounded to one or more cavity walls by grounding elements that engage with the shield and a portion of the cavity wall. The heating element can emit a greater amount of infrared radiation in one direction than an opposite direction, e.g., due to a convex or other shape of the resistance element. Sets of heating elements can be controlled so that a second element begins to emit visible light at a same time that a first element stops emitting visible light. Convection air can be directed at one or more heating elements, which diffuse the air flow or otherwise prevent flow of air directly to food in the cavity.
