Abstract: A method for self-calibrating a sound pickup process that uses a microphone array in a wearable device that also includes a loudspeaker, where the microphone array being in a physical arrangement with respect to the loudspeaker. The method obtains, for each of several microphones of the microphone array, one or more transfer functions that each represent a response of the microphone to sound from a position in an acoustic space. The method determines whether a physical arrangement of the microphone array with respect to the loudspeaker has changed and adjusts the transfer function, for at least one of the microphones of the several microphones, in response to determining that the current physical arrangement of the microphone array with respect to the loudspeaker has changed.

Abstract: A thermal management system having a first mode of operation configured to transfer heat from a first plurality of components of a vehicle in the first fluid flow path and to selectively transfer heat to at least one of a second plurality of components in a second fluid flow path; a second mode of operation configured to transfer heat from the first plurality of components in the first fluid flow path and selectively transfer heat from the second plurality of components in an alternative second fluid flow path; and a third mode of operation configured to transfer heat from both the first plurality and the second plurality of components of the vehicle in a third fluid flow path. A controller is operable to selectively change the mode of operation between the first mode of operation, the second mode of operation and the third mode of operation based on operating conditions of the vehicle.

Abstract: A battery pack assembly for a vehicle includes a tray assembly fixed under a floor panel in a vehicle height direction and on which a battery pack-associated component is placed. The tray assembly has a base with a first edge portion and a second edge portion opposite the first edge portion. Each of the first and second edge portions is extended upward relative to the height direction from the base and secured to a frame assembly. A deformation feature is provided at a transition area between the base and the second edge portion. During a crash event the second edge portion is adapted to bend toward the base via the deformation feature allowing a displacement of the base in one of a vehicle front-back direction and a vehicle width direction and also downward in the height direction.

Abstract: A chiller/heater combination system for electric vehicles. The system includes a heat exchanger for 3 fluids. A first fluid is a high-temperature heat exchange fluid that cools components that generate heat, a second fluid is air conditioning refrigerant, and a third fluid is low-temperature heat exchange fluid used to heat or cool the motive unit. The heat exchanger may be a stacked plate design for three fluids. The low-temperature heat exchange fluid is cooled or heated in the three-fluid heat exchanger.
