Abstract: Various implementations include a method of manufacturing one or more devices. The method includes obtaining a base portion of a non-shape-memory metal, disposing one or more shape-memory metal portions along the base portion, and joining at least a first layer of the non-shape-memory metal to the base portion using ultrasonic additive manufacturing. The shape-memory metal portions are disposed along a first base surface of the base portion. The shape-memory metal portions have a first portion contacting the base portion and a second portion spaced apart from the first portion and extending from the base portion. The first layer is joined to the base portion using ultrasonic additive manufacturing and has a first layer surface that is joined to the first base surface. The first layer surface contacts the shape-memory metal portions when the first layer is joined to the base portion.

Abstract: A physical access control system enables acceptable portal entry codes upon receiving each physical access request by operating on the elapsed time from a previous physical access request to generate a temporal credential. The controller receives a plurality of physical access requests from a plurality of mobile application devices. Upon authenticating the first access request, the controller eliminates repetition from the space of acceptable successor requests from each mobile application device. Monotonic nonces advance the range of temporal code matches. Entry code generation is decentralized to distributed application devices and is inherently unknowable until a successor access request is initiated by the same application device.

Abstract: A transition structure includes a metallic portion, a fiber portion including a plurality of tows embedded within the metallic portion and extending out from the metallic portion forming a fabric, and a binding material forming a matrix surrounding the fiber portion embedded within the metallic portion. The fiber portion may be attached to or form part of a composite vehicle component. The transition structure may join a metallic component and a composite component. The transition structure may be manufactured by creating first channels within a layer of a metallic substrate, inserting fiber tows into the first channels, placing a first metallic layer over the metallic substrate and the fiber tows, consolidating the metallic layer to the metallic substrate, and binding the fiber tows within a resin. Prior to binding, additional layers of channels and fiber tows may be consolidated onto the first metallic layer.

Abstract: A composite component includes a reinforcement bonded to a base component by a bond formed by, or reinforced with, a localized coupling in the base component. The bond may be formed by ultrasonic additive manufacturing. The localized coupling may include a compression of the base component, a weld in the base component, or a heat affected zone of the weld. Where the bond is formed by the localized coupling, the localized coupling encompasses the reinforcement. Where the bond is reinforced with the localized coupling, the localized coupling may encompass the reinforcement, or be arranged at an inside radius of a turn in the reinforcement. The reinforcement results in the composite component having enhanced properties such as lower density, increased strength, stiffness, or energy absorption capabilities.

Abstract: A method of adding a reinforcement to a metal blank prior to a forming process. The reinforcement is attached via ultrasonic additive manufacturing (UAM) to create a composite blank which is then subjected to a forming process to bend and deform the composite blank and form a reinforced vehicle component. The reinforcement is placed on the metal blank such that after being subjected to the forming process, there is reinforcement in key areas of the formed vehicle component. The reinforcement results in the final formed vehicle component having enhanced properties such as lower density, increased strength, stiffness, or energy absorption capabilities.
