Abstract:
An actuation assembly adapted for driving a load and protecting against overloading and overheating conditions, includes an actuator defining a stroke when exposed to an activation signal, and further includes a protection device comprising a superelastic shape memory alloy element connected in series to and cooperatively configured with the actuator, and operable to both produce a secondary work output path for the actuator and discontinue the signal.
Abstract:
A camera system includes a body defining a cavity therein, and a camera attached to the body within the cavity and including a lens. The camera system also includes a shape memory alloy transitionable between a first state and a second state in response to a thermal activation signal, and a wiper configured for wiping debris from the lens. The wiper is attached to the camera and is actuatable by the shape memory alloy. The shape memory alloy transitions between the first state and the second state to actuate the wiper so that the wiper contacts and translates across the lens and thereby wipes debris from the lens.
Abstract:
A method of achieving a target activation parameter, such as a predetermined response time and/or consistency when thermally activating at least one active material element, such as a shape memory alloy actuator or shape memory polymer hinge, includes deciding whether to prime the element based on energy efficiency and/or overall system costs/performance.

Abstract:
Presented herein are active textile structures with selectively variable surface friction characteristics, methods for making/using such structures, and vehicle components fabricated with electronically controlled textile structures with modifiable surface friction characteristics. An active textile system for governing frictional force levels at an interface with a user or object is presented. The system includes a textile structure that is fabricated from interlaced first and second textile filaments. Each textile filament has a respective texture that exhibits a distinct coefficient of friction. The textile structure has an outer and/or upper contact surface at the interface with the user/object. An actuating element, which is connected to the textile structure, is operable to selectively transition the textile structure between first and second states. The first state includes the first textile filament defining the textile structure's outer contact surface, whereas the second state includes the second textile filament defining the outer contact surface.

Abstract:
A trim component for attachment to a vehicle seat includes a first portion and a second portion. The first portion is disposed on a first side of the trim component and defines a first knit. The second portion is disposed on a second side of the trim component and defines a second knit distinct from the first knit. The first and second portions are integrally knitted. The trim component is configured to be installed on or more support members of the seat. The first side is configured to face the support member. The second portion is configured communicate with an occupant of the seat. In various aspects, the first portion includes a first yarn and the second portion includes a second yarn that is distinct from the first yarn with respect to one or more of density, thickness, and material. In various aspects, the first yarn is a heat-activated yarn.
Abstract:
A knitted seat trim cover for attachment to a vehicle seat includes a knitted trim panel configured to be installed over at least one foam support member of the vehicle seat and a fastener member integrally knitted in the knitted trim panel. The fastener member is configured to connect the knitted trim panel to the vehicle seat and at least a portion of the fastener member is made of a heat-activated yarn.
Abstract:
A textile assembly includes a knitted or woven textile panel of non-conductive fibers, and defines a first delimited area. A first conductive filament is knitted or woven into the textile panel in the first delimited area, and is arranged to form an electronic device, such as a sensor or a switch, in the first delimited area. The textile assembly may further include a third conductive filament that is knitted or woven into the textile panel in a second delimited area. The third conductive filament is arranged to form a second electronic device, such as a sensor or a switch, in the second delimited area. A controller may use a signal from the first electronic device and the second electronic device to execute a function, such as generate a pressure map of the textile panel.
Abstract:
A vehicle includes at least one image capture device and a user display configured to display images receive from the at least one image capture device. The vehicle also includes a controller programmed to generate a user prompt to set a home vehicle position in response the vehicle entering a first parked state. The controller is also programmed to store at least one reference image indicative of an area in a vicinity of the vehicle corresponding to the home vehicle position. The controller is further programmed to collect a current image corresponding to a current vehicle position in response to a subsequent approach toward the vicinity, and compare the current image to the reference image. The controller is further programmed to generate a user display depicting the vicinity, the current vehicle position, and the home vehicle position.
