摘要： A method for controlling welding forces of a weld tip to a work piece during a vibration-welding process includes positioning an Active Material (AM) element adjacently to a welding interface, and varying a property of the AM element to regulate the welding force. The AM element may be disposed between the weld tip and a weld face thereof, or between the work piece and an anvil. The property may be varied as a function of heat generated by the welding process. A property of each of a plurality of AM elements may be independently and selectively varied via an energy source, or passively. A vibration welding system includes a weld tip and an AM element connected adjacently to a welding interface. The system regulates a welding force applied by the weld tip to a work piece during the welding process by varying a property of the AM element.

摘要： Active material actuator assemblies are provided that enable simplified control systems and faster actuator cycle times. A movable member is provided that has multiple active material components operatively connected to it. The active material components are separately selectively activatable for moving the movable member. Movement of the movable member via activation of a first of the active material components triggers activation of the second active material component to further move the movable member. Alternatively or in addition, previously activated active material components are protected from undesired stretching during activation of another active material component or, when desired, an active material component may be reset via activation of another of the active material components in order to prepare it for subsequent activation.

摘要： A screen apparatus includes a screen assembly and structure. The structure defines a cavity having an opening to a vehicle passenger compartment. The screen assembly includes a frame and a video screen mounted with respect to the frame. The screen assembly is selectively movable between a retracted position in which the screen is inside the cavity and concealed from view, and a deployed position in which the screen is outside the cavity and visible from the passenger compartment. The screen apparatus is configured such that the movement of the screen assembly between the retracted and deployed positions is restricted to substantially linear translation.

摘要： A vent assembly is disposed within an interior space of a vehicle for opening and closing fluid communication between the interior space and an exterior of the vehicle. The vent assembly includes a housing defining a plurality of openings and a plurality of vanes disposed in the openings. An actuator mechanism moves the vanes between an open position and a closed position, and includes a shaped memory alloy (SMA) member for actuating the vanes between the open and closed positions. The SMA member is activated when a hatch of the vehicle is open to move the vanes into the open position and thereby open fluid communication between the interior space and the exterior to alleviate excessive air pressure buildup during closure of the hatch.

摘要： A method for executing mechanical overload protection to prevent commanding a control signal to a linear actuator that may mechanically overload the linear actuator when an overload condition of the linear actuator is detected, the linear actuator utilized for controlling a movable element associated with the linear actuator responsive to the control signal, includes monitoring an overload condition based on position change of the movable element associated with the linear actuator during an integration period and excess energy during the integration period, de-energizing the linear actuator when an overload condition has been detected, monitoring an overload retry counter based on the number of cycles the overload condition is detected, comparing the overload retry counter to an overload retry threshold, an reenergizing the linear actuator when the overload retry counter is less than the overload retry threshold and maintaining de-energizing of the linear actuator when the overload retry counter is at least the overload retry threshold.
