摘要:
A multi-functional apparatus employs an electromagnetic device. The electromagnetic device selectively causes movement of an intermittent motion mechanism thereby moving a mechanical device coupled thereto. A main driving gear is rotated from the wiper positional range in either direction to access one or another adjacent release positional range, but not necessarily both at the same time.

A multi-functional apparatus employs an electromagnetic device. The electromagnetic device selectively causes movement of an intermittent motion mechanism thereby moving a mechanical device coupled thereto. In another aspect of the present invention, a single electric motor selectively actuates three intermittent motion mechanisms thereby causing three mechanical devices coupled thereto to operate. In a further aspect of the present invention, a clutch mechanism selectively drives a window wiper. A method for operating the multi-functional apparatus of the present invention is also provided.
摘要:
A vehicular, infrared, multiplexing system controlling various vehicular or automotive electrical function loads, such as, for example, lights, window motors, seat motors, door locks, engine start and the like, wherein control and sensing signals are transmitted within the interior of the vehicle by randomly reflected, infrared radiation or similar optical energy carrying electronically intelligible information. The infrared system does not require or rely on direct, light-of-sight or controlled reflection or a continuous optical circuit, but instead relies on randomly reflected, scattered, diffused, infrared radiation reflected from various interior surfaces of the vehicle, including, for example, practically all interior surfaces, such as the windshield, side and rear windows, seats, headliner, instrument panel, rear window, door trim panels, etc. One or more central transmitter/receivers are included in the vehicle's interior, including the instrument panel using the windshield, the rear of the center console using the headliner, and/or in the rear package deck using the rear window. A serial, multiplex transmission with half-duplex, serial data bi-directionally format is used, including a sync code alerting the load devices of transmission start, a unique vehicle code (e.g., the VIN), the central control unit's MUX command, the central unit's cyclic redundancy error checking code, remote unit address, remote's MUX response, and remote's cyclic rendundancy code. Because all system information is transmitted by infrared, only one wire, used for twelve volt DC power, is required to each of the load units, with the vehicular chassis serving as ground return.

An indication system (10) for a vehicle (11) includes a radio frequency circuit (12) with a transponder (84) and an in-vehicle RF tagged element (18). The transponder (84) transmits a status request signal. A first radio frequency identification tag (84) is coupled to the in-vehicle RF tagged element (18). The tag (84) inductively generates a current status signal associated with the in-vehicle element (18) and in response to the status request signal. A method of tracking, identifying, and determining the presence and status of an in-vehicle RF tagged element (18) includes transmitting a status request signal. The status request signal is inductively received via multiple radio frequency identification tags (84, 86) that are associated with the in-vehicle RF tagged element (18). A current status signal is transmitted from the radio frequency identification tags (84, 86). An in-vehicle task is performed in response to the current status signal.

A vehicle seat assembly includes a seat back that is pivotally connected to a seat bottom, a lock mechanism that is configured to inhibit the seat back from pivoting when locked and to permit the seat back to pivot when unlocked, and a release and drive mechanism. The release and drive mechanism includes a mounting member, a drive gear that is rotatable with respect to the mounting member and that is connected to the lock mechanism, and a motor that is connected to the drive gear. The drive gear is rotationally limited to a defined angular range. The motor rotates the drive gear through the defined angular range which moves the lock mechanism to an unlocked state and thereafter causes the seat back to pivot.
摘要:
A linear motion actuator is disclosed in which an actuator shaft is held in a ready position by a latching ring. A spring is attached to the actuator shaft to exert a biasing force on the actuator shaft biasing it toward its actuated position. The latching ring receives one end of the actuator shaft and has locking elements that hold the actuator shaft in the ready position. A latching ring is rotated to selectively release the locking element. A shape memory alloy link extends partially around the latching ring and is secured to the latching ring. The link is shortened when current is applied to the link causing the link to rotate and release the locking element.
摘要:
A shape memory alloy (SMA) system suitable for use in any number of environments, including but not limited to latching and unlatching vehicle seat tracks. The system including any number of configurations to support any number of operations, including but not limited to push-push, pull-pull, push-pull, and pull-push operations.
摘要:
An actuator for a latch assembly for securing a latched member that is linked to a trigger. The trigger may be a shape memory alloy actuating element that is actuated in response to receiving an electrical signal. The trigger may be mechanically reset to a locked state by the latched member. A method of operating the latch is also disclosed wherein the trigger is actuated in response to an electrical signal resulting in a force being applied in a first direction to a cable that connects the trigger to release the latch. The trigger is reset by exerting mechanical force on the trigger in the opposite direction. The latch system may be applied to a vehicle seat having a seat back that pivots relative to a seat base to allow the seat back to pivot over the seat base.

An actuator configured to actuate a member. The actuator optionally including capabilities for storing and releasing kinetic energy. The actuator being suitable for use in any number of environments, including but not limited to facilitating seat folding operations.
摘要:
An electronic trigger assembly for triggering an actuator, the electronic trigger assembly having a trigger member capable of connection to the actuator. The trigger member may be configured for rotation between a first position and a second position and the trigger member may be able to trigger the actuator as the trigger member rotates between the first position and the second position. The trigger member may also include a guide. A shape memory alloy member may be connected to the trigger member and may be received by the guide such that a substantial portion of the shape memory alloy member is disposed in a curvilinear arrangement. The shape memory alloy member may contract when electrified. The shape memory alloy member may be confined by the guide to contract along a path such that the shape memory alloy member exerts torque on the trigger member and causes the trigger member to rotate from the first position to the second position.
