  • Patent number: 7804414
    Abstract: A device for detecting a collision of a vehicle with an obstacle includes an enclosed space positioned behind a front bumper cover. Deformation or displacement of the bumper cover due to a collision is transmitted to the enclosed space. Air pressure in the enclosed space and its temperature are measured by sensors and electrical signals representing the pressure and the temperature are fed to an electronic control unit that determines whether the enclosed space is hermetically closed or not based on the pressure and the temperature of the air in the enclosed space. If the enclosed space becomes non-hermetical due to a collision impact, the air therein leaks and the pressure therein becomes atmospheric pressure irrespective of the temperature of the air in the enclosed space. Therefore, the hermetical condition of the enclosed space is surely detected.

  • Patent number: 7582349
    Abstract: The present invention relates to a morphing cellular structure. The morphing cellular structure comprises a group of unit cells with each unit cell configured to have a cellular geometry. The group unit cells are formed of an active material, where the active material has both a first state and a second state. The active material is responsive to an actuation signal such that when the actuation signal is actuated, the active material is deformed from the first state to the second state, thereby changing the volume of each unit cell affected by the actuation of the actuation signal and morphing the cellular structure. Furthermore, both a passive material and at least one additional active material can be attached with the active material, allowing a user to selectively change the shape of the cellular structure.

  • Publication number: 20090058110
    Abstract: A trailer crash attenuation assembly includes a longitudinal hollow member adapted to act as a hydraulic cylinder at one end, hydraulic fluid disposed in the hydraulic cylinder and a tank connected to the hydraulic cylinder to receive and store said hydraulic fluid expressed from the hydraulic cylinder. A first longitudinal telescopic member is adapted to slide into and out of the longitudinal hollow member and is adapted to act a piston. Two other longitudinal hollow members are positioned substantially parallel to and on either side of the first longitudinal hollow member and are connected to the first longitudinal hollow member. Two telescopic members are adapted to slide into and out of the two other longitudinal hollow members respectively. A casing is connected at its proximal end to all three longitudinal hollow members, is adapted at its distal end to receive a crash cushion; and has a pair of wheels.

  • Patent number: 7472935
    Abstract: An apparatus for impact dispersal of a force applied to a vehicle, such as a motor vehicle or other carrier. The apparatus includes a hydraulic cylinder in fluid communication with a relief valve and a flow restrictor connected in series. The piston rod of each cylinder receives the force of an impact, which causes the fluid in the cylinder to undergo an increase in pressure, which is relieved by multiple relief valves and serially connected flow restrictors. In one embodiment, the relief valves and the flow restrictors are incorporated into a single valve. The system responds to an amount of force caused by an impact and disperses the force accordingly at a controlled rate. Applications for such an embodiment include connection to vehicle bumpers, to a seat back where the cylinder is double-acting, and to landing feet for air-drop carriers.

  • Patent number: 7036844
    Abstract: A multi-chambered bumper airbag for deployment from the bumper of a vehicle in the event of a collision with another vehicle is provided. The airbag comprises a main inflatable portion that, when inflated, absorbs the energy from contact with a structural member of the struck vehicle. The airbag also has one or more secondary inflatable portions concentric with the main inflatable portion. Because the secondary inflatable portions have a lower gas pressure than the main inflatable portion, they are used to cushion the occupant of the struck vehicle should the occupants' head and neck be forced out of the window of the struck vehicle.

  • Patent number: 6988754
    Abstract: A cost effective bumper for a vehicle is provided that develops maximum resiliency of an inflated spare wheel to dampen shock of impacts so as to reduce injury to the occupants and reduce repair cost of the vehicle, without need for additional parts or cost. The bumper is especially suited to increase the safety of small automobiles, and storage of the spare wheel in the bumper assembly gives added room in the luggage compartment. The introduction of Hybrid power plants for small automobiles allows timely opportunities for new placements of engine components, to best accommodate the bumper assembly of the present invention.

  • Patent number: 6942261
    Abstract: A linear actuator with an internal dampening mechanism is disclosed. The actuator has a housing has a first end and a second end and forms an internal chamber. A constricted opening is also added to the actuator at the first end. A piston is disposed within the housing and is capable of sliding along the chamber. The piston has a head portion and a shaft portion. The shaft portion is slidable through the constricted opening whereas the head portion is not slidable through the constricted opening. A fluid is also added to the actuator. The fluid is disposed within the housing. In one embodiment, the actuator is constructed such that the sliding of the shaft portion forces a fluid through the constricted opening such that the movement of the piston is dampened. In an alternative embodiment, the actuator includes one or more second pistons and an orifice.

  • Patent number: 6749218
    Abstract: Externally deployed airbag system for a vehicle including one or more inflatable airbags deployable outside of the vehicle, an anticipatory sensor system for assessing the probable severity of an impact involving the vehicle based on data obtained prior to the impact and initiating inflation of the airbag(s) in the event an impact above a threshold severity is assessed, and an inflator coupled to the anticipatory sensor system and the airbag for inflating the airbag when initiated by the anticipatory sensor system. The airbag may be housed in a module mounted along a side of the vehicle, in a side door of the vehicle (both for side impact protection), at a front of the vehicle (for frontal impact protection) or at a rear of the vehicle (for rear impact protection). Also, the externally deployed airbag can be deployed to cushion a pedestrian's impact against the vehicle.
