Abstract: A releasable fastening system for retaining two surfaces at each other or disengaging the two surfaces from each other comprises a first electrode disposed at a first surface, a second electrode disposed at a second surface, and a polymer film disposed between the first and second electrode, and an electrolyte disposed in electrical communication with the first electrode, the polymer film, and the second electrode. A volume of the polymer film is controllably variable to cause the retention of the first surface at the second surface. A method of releasably fastening adjacently-positioned surfaces comprises disposing a first electrode at a first surface, disposing a second electrode at a second surface, and increasing the volume of an electrolyte disposed in electrical communication with the first electrode and the second electrode to cause the retention of the first surface at the second surface.

Abstract: A method for achieving a constant average deceleration of a vehicle is disclosed. In an exemplary embodiment, the method includes comparing an effective load mass of the vehicle to a baseline load mass. If the effective load mass differs from the baseline load mass by at least a designated percentage, then upon detection of a vehicle impact, energy absorbing structures within the vehicle are adjusted so as to alter crush forces of the vehicle, thereby resulting in a desired average deceleration of the vehicle.

Abstract: A mechanical, active crash pulse management structure for providing modification of crash pulse, wherein the structure has a dormant (initial) state volume, but then in the event of a crash, timely expands into a much larger deployed volume for providing management of an expectant crash energy. The preferred crash energy management structure is a before expansion honeycomb celled material brick, wherein expansion of the honeycomb brick is in a plane transverse to the cellular axis of the cells thereof, and crash crush is intended to be parallel to the cellular axis. In the event of a crash, either an active or passive activation mechanism is provided for causing expansion of honeycomb celled material.

Abstract: Identifying an object includes the steps of using a sensor onboard a subject vehicle to identify an imminent impact between the subject vehicle and an object, directing and transmitting an elicitation signal to the object from the subject vehicle, receiving onboard the subject vehicle a response signal from the object providing information that positively identifies the object, using the positive identification information to predict a severity level of the imminent collision, and selectively deploying at least one responsive device onboard the subject vehicle according to the predicted severity level. Also, a system for implementing the method is provided.

Abstract: A knee bolster system is capable of automatic extension and retraction during specified scenarios that are determined based on sensor input. A microprocessor electrically controls an actuator capable of extending at least one telescoping mechanism which is rigidly engaged to a knee bolster pad located in the lower portion of an instrument panel at knee height to an occupant. Each telescoping mechanism houses a plowing mechanism. This plowing mechanism generates reaction forces during actuation.

Abstract: A method of pre-crash prediction of the severity of an imminent crash of road vehicles is disclosed using a pre-crash sensor, a computer system coupled with pre-crash vehicle condition signal sources and a vehicle communication system onboard each of two vehicles involved in a crash. The method includes the steps of determining that a collision of the vehicles is imminent, exchanging vehicle crash-related information between the vehicles when an imminent collision is determined, computing crash-defining information onboard each vehicle and predicting onboard each vehicle the severity of the imminent collision whereby occupant protection devices of the vehicles may be deployed in accordance with the predicted severity.

Abstract: A motor vehicle body including a plurality of vertical pillars defining therebetween a plurality of door frames for access to a passenger compartment of the vehicle body, a plurality of doors supported by pairs of hinges on the front vertical pillar of each door frame for pivotal movement between closed and open positions, and a light weight side impact protection barrier characterized by high elongational stiffness and high strain-at-failure. The light weight barrier may be employed alone or in combination with a horizontal door beam and includes a synthetic cable in the door made from a plurality of helically braided bundles of fibers selected from a group of fibers consisting of aramid fibers and liquid crystal polymer fibers characterized by a strain-at-failure exceeding about 3%. The synthetic cable includes attachments to the front and rear pillars of the door frame when the door is closed.

Abstract: A crush control system for controlling the crush of spaced vehicle side composite structural rails in the event of either a full frontal impact or an offset frontal impact includes a crush controller for each side rail. An actuator is provided to move crush initiators between an inoperative position, which will cause an uncontrolled crush of the rail, and a deployed operative position, which will cause a controlled crush of the rail at half the crush force as an uncontrolled crush. In one embodiment each crush controller is normally inoperative and is controlled by a sensor for each located on the opposite side of the vehicle to become operative when the sensor is impacted. The crush initiators may take the form of a radiused wedge or a knife cutter, and the actuator maintains the crush initiators in deployed position to sustain the controlled crush.

Abstract: A multi-fabric layer, resin matrix laminated composite tube is disclosed having an end portion adapted for crush initiation by the provision of slits in the fabric of at least the innermost fabric layers of said tube, the lengths of said slits preferably decreasing in progressively outer fabric layers of the laminated material.
