Abstract: A vehicle includes a propulsion system having multiple electric motors. A battery system is connected to the electric motors via a direct current to direct current (DC-DC) converter and an inverter. The battery system includes a battery assembly having a plurality of battery modules. Each of the battery modules has multiple individual battery cells arranged in battery packs, a set of sensors configured to monitor a set of parameters of each battery pack, and a plurality of battery pack mounts. Each battery pack mount includes a base plate and a top plate and an actuator configured to alter a distance between plates. A monitoring unit is configured to monitor a value representative of a battery pack pressure, determine whether the value falls within a pressure threshold window, and maintain the value within the pressure threshold window by actively altering the battery pack pressure.

Abstract: A system and method for personalization of adjustable features of a vehicle. The system includes a processor and an actuator. The processor detectors key points of a person from a two-dimensional image and predicts a pose of the person. The processor translates a respective position of the key points from a two-dimensional coordinate system to a three-dimensional coordinate system based in part on the pose and measurements of distances between the key points. The processor determines a baseline configuration of an adjustable feature of the vehicle based in part on measurements between the key points in the three-dimensional coordinate system. The processor causes an actuator to adjust the adjustable feature to conform to the baseline configuration.

Abstract: One general aspect includes a system having one or more heat pads installed at a vehicle, the one or more heat pads configured to provide infrared energy transmissions to a vehicle component to defrost, defog, or both defrost and defog a surface of the vehicle component. The system may also carry out the following steps: (a) determining that ice or fog or both ice and fog has accumulated on the surface of the vehicle component; and (b) based on the determination made in step (a), activating the one or more heat pads to defrost, defog, or both defrost and defog a surface of the vehicle component.

Abstract: A fluid bypass valve includes a valve member disposed within a valve chamber of a housing. A temperature based actuating mechanism moves the valve member between a first position and a second position in response to a temperature change. A temporary flow control device undergoes a one-time only shape change between a first shape and a second shape. The temporary flow control device enables fluid communication between a first port and a second port when exhibiting the first shape, and does not enable fluid communication between the first port and the second port when exhibiting the second shape. The temporary flow control device exhibits the first shape when having an initial temperature less than or equal to a second pre-defined temperature, and exhibits the second shape in response to a first heating of the temporary flow control device to a temperature that is greater than the second pre-defined temperature.

Abstract: A thermal bypass valve includes a housing defining a bore along a longitudinal axis and having two inlet ports and two outlet ports; a cap disposed within the bore; a shuttle disposed within the bore and reversibly translatable towards and away from the cap along the longitudinal axis between a first fill position, a cooling position, and a bypass position; and an actuator configured for translating the shuttle along the longitudinal axis between the cooling position and the bypass position. The actuator is formed from a shape memory alloy and is transitionable between a first state and a second state in response to a temperature of the fluid.

Abstract: A vibration welding system for joining a wire to a substrate includes a welding pad attached to a sonotrode and an anvil. The welding pad includes first energy directors that are disposed in a first region and second energy directors that are disposed in a second region. A channel is formed between the substrate and the first energy directors when the second energy directors are in contact with the substrate. The channel is configured to accommodate a portion of the wire, and has a depth that is less than a cross-sectional diameter of the wire. The wire and the substrate are clamped between the welding pad and the anvil during operation of the sonotrode. The first energy directors urge the wire towards the substrate during the operation of the sonotrode to effect joining of the wire to the substrate.

Abstract: A climate control device includes a radiant heater for radiating heat and a porous material attached to the radiant heater. The porous material desorbs a plurality of water molecules, in response to the porous material receiving heat from the radiant heater and raising a temperature of the water molecules in the porous material to a boiling temperature threshold. The porous material adsorbs the water molecules in response to the temperature of the water molecules falling below the boiling temperature threshold.
