Abstract:
A ventilating system for a garage is provided. The ventilating system comprises an automatic garage door opening mechanism and a hazardous gas detector. The automatic garage door opening mechanism is configured for wireless communication and to move a garage door between an open position and a closed position. The hazardous gas detector is configured for wireless communication and to sense the presence of a hazardous gas within the garage. The hazardous gas detector wirelessly instructs the automatic garage door opening mechanism to move the garage door to the open position when the hazardous gas reaches a predetermined level in the garage. As such, the garage is ventilated.
Abstract:
A sliding window panel assembly for a motor vehicle. The assembly includes a stationary window panel having an opening formed therein, at least one guide rail coupled to the stationary window panel below the opening and above a bottom edge of the stationary window panel, a shoe slidably received within the guide rail and configured to slidably move within the guide rail, a movable window panel mounted onto the shoe such that the movable window panel slidably moves with the shoe. The movable window panel can slidably move with respect to the stationary panel along a movable panel path. The lead screw drive unit engages the shoe and is adapted to move the shoe and the movable panel along the movable panel path within the guide rail.
Abstract:
A releasable seal assembly for selectively removing a component from an other component, wherein the component and the other component are in sealing engagement with the releasable seal assembly. The releasable seal assembly includes a seal structure comprising an active material, wherein the active material is effective to undergo a change in at least one attribute in response to an activation signal, wherein the change in the at least one attribute changes a shape and/or modulus property of the seal structure; an activation device adapted to provide the activation signal in operative communication with the active material; and a controller in operative communication with the activation device. Also disclosed herein are methods for the releasable seal assembly.
Abstract:
Active seal assemblies employing active materials that can be controlled and remotely changed to alter the seal effectiveness, wherein the active seal assemblies actively change modulus properties such as stiffness, shape orientation, and the like. In this manner, in seal applications tailored for vehicles such as in a vehicle door application, door opening and closing efforts can be minimized yet seal effectiveness can be maximized.

Abstract:
Door closure assist assemblies that assist in providing a final closing motion generally includes an extender portion comprised of an active material adapted to linearly expand in response to an activation signal and a releasable fastener having one component in movable communication with the extender portion and a second component attached to the other selected one of the door and doorframe. During operation, the door closure assist assembly provides the final closing action.
Abstract:
A rolling door error-start prevention device, comprising: a base plate provided at a lateral side of the upper rolling shaft accommodating chamber of rolling door; a rolling machine having a housing-base and a sprocket which drives said rolling shaft of the rolling door through a chain rolling, and which is fixed on the drive shaft; wherein said housing-base of the rolling machine is pivoted, in a swingable manner, to its upper position, at a base plate through a shaftpin, one or two slot(s) is (are) formed at a position below said base, and a guiding rod loosely passes through said slots and slidably pivots to said base; a tension spring, positioned oppositely to the direction of rotation of the rolling shaft, and applying a tension force onto lower portion of the housing-base of the rolling machine to maintain the base in a balanced condition; a sensor device, provided at the lower portion of the housing-base of the rolling machine, and used to detect the position of the base in such a manner that the sensor can switch off the power supply for a delay circuit and supply a reverse current to the rolling machine to rotate in reverse direction to cause the rolling door to descend back to its original position, when a deflection of the base due to the exceeding of torque load beyond a critical point is detected.
Abstract:
A vehicle-based door opening system for opening a door at a building includes a vehicle-based transmitting unit, a control and an actuating device. The transmitting unit is positioned at the vehicle and operable to transmit a first signal, and the actuating device is positioned at the building and receives the first signal from the vehicle-based transmitting unit. The control is operable to control at least one vehicle-based accessory, such as a door lock mechanism, in response to the first signal. The actuating device receives a domestic hand held garage door opener transmitting unit associated with a door opening device at or near the door and actuates the domestic hand held garage door opener transmitting unit in response to the first signal. The domestic hand held garage door opener transmitting unit transmits a second signal to actuate the door opening device to open or close the door.
Abstract:
A conductive hinge is made of a superelastic shape memory alloy such as nitinol (NiTi) having a large elastic strain limit for enabling the hinge to bend around a small radius during stowage and flexible return to a trained rigid hinge position. The hinge is conductive enabling use of the hinge as a conductor for routing power through multiple solar cell panels interconnected by the hinges forming a hinged solar cell array that is deployed when the hinges are released from the bent stowed configuration to the rigid deployed configuration when the hinges further function as latches to lock the panels in place.
Abstract:
A conductive hinge is made of a superelastic shape memory alloy such as nitinol (NiTi) having a large elastic strain limit for enabling the hinge to bend to a small radius during stowage for flexible return to a trained rigid hinge position by training the shape memory alloy to assume a predetermined deployed configuration when released from a stowage configuration. The hinge is trained by forging at a temperature above a training temperature. The hinge is released to deploy solar cell panels as the hinges unfold to the forged trained deployed configuration.
