Abstract: A battery electric device includes a battery cell, e.g., a pouch, prismatic, or cylindrical cell, connectable to an electric load, and a direct-to-air thermoelectric assembly (TEA) or another heat pump connected to a surface of the cell. A pressure control device maintains constant pressure on the cell surface when the cell is connected to the load. Connection to the load causes the TEA/heat pump to pump heat from the cell. A sensor, e.g., thermocouple(s) and/or heat flux sensor(s), generate an output voltage signal indicative of the quantity of heat. A battery system includes the device and a processor in communication with the cell, the load, and the power supply. The processor generates an electronic control signal in response to the quantity of heat.

Abstract: A user device may detect speech and use “early exiting” when identifying a potential operational command in the detected speech. The implementation of early exiting may be based on a variable threshold, where variable sensitivity settings for the threshold may be used to control how quickly, and whether, an “early exit” or early prediction of an operational command will occur. An early exit threshold may be adjusted, for example, based on network conditions, to ensure optimal operational command determination from the audio.
