Abstract: A welding block for a welding system secures together first and second components of a workpiece for a motor vehicle to reduce distortion of the first and second components during a welding process. The welding block includes a jig mechanism that has a proximal surface for receiving a load from an arm of the welding system. The jig mechanism further includes a distal surface for engaging the first component and securing the first and second components to one another during the welding process. The jig mechanism defines a passage, such that heat flows from the distal surface to a coolant flowing through the passage. The welding block further includes a sensor coupled to the jig mechanism for detecting a measured variable associated with at least one of the first and second components.

Abstract: A thermal management device for dissipating heat from an electrical component includes a volume of working fluid configured to change from a liquid state to a vapor state in response to being heated by the electrical component. The thermal management device also includes a working fluid chamber configured to move the working fluid. The working fluid chamber includes an impermeable outer portion and a porous inner portion integrally formed with and connected to the impermeable outer portion. The inner portion is configured to move the working fluid when in the liquid state toward the electrical component. The impermeable outer portion is made of a first material and the porous inner portion is made of a second material. The first material is different from the second material.

Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

Abstract: A fluid flow control device includes a resilient substrate translatable between a first flattened position and a second extended position, and an actuator attached to the resilient substrate. The actuator is configured for translating the resilient substrate from the first flattened position to the second extended position. The actuator is formed from a shape memory alloy transitionable between a first state and a second state in response to a change in temperature of the shape memory alloy. A fluid flow control system includes a rotor shield and the fluid flow control device attached to the rotor shield.

Abstract: Systems and methods are provided for locating a pair of components relative to one another using complex surfaces. One component has a complex surface, where the complex surface is smoothly contoured. Another component is shaped to be connected with the first component. A fixture locates the first component relative to the second component. The fixture includes a locator with a complex surface region shaped to mate with the complex surface of the one component to locate the fixture relative to that component. The fixture includes another locator to locate the fixture relative to the second component.

Abstract: A system and method for additive manufacturing are provided. The system includes a structure defining a chamber for manufacturing parts via additive manufacturing. A powder metal applicator is configured to deposit layers of powder metal material to build a part on a build platform. A laser source is configured to direct one or more laser beams onto each layer of powder metal material to fuse the powder metal material, wherein metal condensate is created by the laser beam(s) contacting the powder metal material. An element spaced apart from the layers of powder material has a temperature different than the chamber temperature, so that the element is configured to attract or repel the metal condensate by virtue of the temperature differential between the element and the chamber. The method includes using the element having the different temperature to attract or repel the metal condensate within the chamber.

Abstract: Systems and methods are provided for gripping of a workpiece with a layer jamming structure having rigid datum structures. A system includes a layer jamming structure configurable in an inactivated conformable state, with a membrane defining an internal cavity containing a number of overlapping material layers. The rigid structures engage the layer jamming structure. A pressure system includes a pump coupled with the internal cavity to change a pressure therein to transform the layer jamming structure from the inactivated conformable state to an activated rigid state disposed around the workpiece. The rigid structures help conform the layer jamming structure to the workpiece during transformation to the activated rigid state and to present datum fixturing surfaces in the activated rigid state.

Abstract: An occupant support structure and a method of customizing an occupant support structure. The occupant support structure may comprise a base and a reconfigurable cushion carried by the base. The reconfigurable cushion may include an occupant support surface and a bladder. The bladder may include an outer wall that defines an inner cavity underlying the occupant support surface and two or more overlapping material layers disposed within the cavity. The overlapping material layers may be adapted to selectively transition from a compliant state to a rigid state and vice versa by selective control of a pressure condition across the outer wall of the bladder to reconfigure or conform the occupant support surface of the cushion to a contour of a portion of an occupant supported by the cushion.
