Abstract: A post-build powder removal system includes a work bed, a platform wall having at least one powder evacuation port, and an evacuation port sealing system operable for selectively closing and opening the powder evacuation port. The platform wall cooperates with the work bed to define a powder chamber. The evacuation port sealing system includes an external sleeve slidingly fitted onto the exterior surface of the platform wall such that the external sleeve is slideable in a first direction closing the at least one powder evacuation port and slideable in an opposite second direction opening the at least one powder evacuation port.

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 stretchable adjustable-stiffness assembly includes a casing and first and second friction layers. The casing can be fluidly sealed and includes an interior compartment containing a fluid. The fluid can shift between a first interior pressure and a second interior pressure less than the first interior pressure and an exterior pressure. The first and second friction layers are disposed within the interior compartment. The assembly can shift between relaxed and fixed configurations. In the relaxed configuration, the fluid has the first interior pressure, the casing is stretchable between a first dimension and a second dimension greater than the first dimension, and the assembly has a first stiffness. In the fixed configuration, the first fluid has the second interior pressure, the casing length is fixed, the first and second friction layers are engaged, and the assembly has a second stiffness greater than the first stiffness.

Abstract: A passive airflow regulation system for controlling temperature of a heat-absorbing subassembly is disclosed. The passive airflow regulation system includes a duct configured to provide a conduit for an incident ambient airflow to the heat-absorbing subassembly. The duct is arranged proximate to the heat-absorbing subassembly. The airflow regulation system includes a valve configured to control passage of the incident ambient airflow through the duct. The airflow regulation system also includes an actuator employing a phase-change element configured to selectively store and release energy in response to changes in temperature and stress. The actuator is arranged at the heat-absorbing subassembly and configured to select a position for the valve between and inclusive of fully-opened and fully-closed in response to a temperature of the heat-absorbing subassembly. The airflow regulation system can be arranged on a vehicle having a vehicle body including a first body end configured to face the incident ambient airflow.

Abstract: Malfunction or failure of mechanical, electrical, and electro-mechanical equipment, for example, equipment used in manufacturing operations, is often preceded by an increase in the operating temperature of at least some portion of the equipment. A temperature-sensitive, active material-containing actuator is pre-selected to operate at a pre-determined temperature indicative of impending equipment failure and placed in thermal contact with the equipment. If the equipment achieves the pre-selected temperature the actuator signals this by closing an externally-powered circuit to enable or provide a suitable alarm signal. Additionally, the actuator may close a second circuit connected to a machine controller to alert the machine controller to take some pre-programmed action. Selected actuators are based on shape memory alloys (SMA) adapted to operate over a temperature range sufficient to encompass the expected range of pre-determined temperatures.

Abstract: A closure release device includes a housing fixedly attached to a closure and an actuating lever rotatably disposed on an axis of rotation on the housing. A crank lever is rotatably disposed on the axis of rotation. A coupling member is to selectively couple the actuating lever to the crank lever for rotation together. A shape memory alloy (SMA) actuator is to selectively cause the coupling member to selectively couple the actuating lever to the crank lever. The SMA actuator is electrically actuated. The crank lever is to connect to a latch to selectively release or engage the latch in response to a coupling state of the actuating lever with the crank lever and an actuation state of the actuating lever.

Abstract: A powder bed fusion system includes a powder bed including a build surface and a vacuum system. The vacuum system includes a collection device positioned over the build surface. The collection device includes a body, a pathway defined in the body, wherein the pathway ends in a passageway opening, and a particle retainer connected to the body near the passageway opening. A method of forming a component includes forming a layer of unfused metal powder on a powder bed with a recoater, introducing gas to the powder bed and applying a vacuum with a collection device, fusing a portion of the layer of unfused metal powder on the powder bed with a heat source to form a component layer and generating contaminants, collecting the contaminants from the powder bed with the gas and the vacuum applied by the collection device.
