  • Patent number: 7377156
    Abstract: A tire pressure monitor system is provided including a sensor housing forming an internal housing mount chamber. An air inlet port is formed on a housing side surface and is orientated parallel to the wheel rim rotational axis. A sensor assembly including an air pressure sensor element is mounted within the internal housing mount chamber. A filter element and a gasket element are positioned between the air pressure sensor element and the air inlet port. A potting material fills the internal housing mount chamber. The filter element and the gasket element creating an air pressure flow path from the air inlet port to the air pressure sensor element.

  • Patent number: 7064506
    Abstract: A method for controlling a vehicle power seat motor including the steps of generating at least one control signal using a controller, and adjusting the speed of the motor in response to the at least one control signal such that speed of the motor is maintained to a predetermined curve. Maintaining the speed of the motor to the predetermined curve reduces at least one of mechanical wear, erratic motion, and noise of a respective seat mechanism.

  • Publication number: 20040173565
    Abstract: A wide-mouth blow-molded plastic container capable of accommodating, without undesirable distortion, super-baric pressures when filled with volatile food products and pasteurized, and sub-baric pressures after cooling to ambient temperatures. A method of packaging a food product in the container is also disclosed.

  • Patent number: 6131436
    Abstract: A method and system for wear testing a seat by simulating human seating movement are disclosed wherein load distributions and histories experienced by the seat are more accurately simulated. The system utilizes a robot and a robotic human body simulator including a pelvic girdle mounted at a distal end of an arm thereof wherein a seat back surface as well as a seat bottom surface are wear tested. The simulator includes a plurality of drives which receive drive control signals from a robot controller for moving a thoracic cage and femurs of the simulator relative to and independent of one another and the pelvic girdle to test wear characteristics of the seat bottom surface and the seat back surface of the seat under test for a plurality of cycles.

  • Patent number: 5753834
    Abstract: A method and system for wear testing a seat by simulating human seating movement utilizing a robot and a robotic human body simulator mounted at a distal end of an arm thereof wherein a seat back surface as well as a seat bottom surface are wear tested without the need of video tape interpretation by a user of the system. Measured data is obtained by measuring 3-D locations of parts of a human during ingress of the human onto a calibration seat and egress of the human from the calibration seat. The measured data represents locations of the parts of the human. A control program is generated on the measured data by transforming the measured data to control program targets. Load and/or pressure feedback is provided for control program verification.

  • Patent number: 5706991
    Abstract: A holder for tool transport and method for transporting tools is provided. The holder includes a compartmentalized top section with an optional handle. A securable cover may be included to protect tool during transport. The base of the holder includes both a contiguous edge that provides suitable support during placement on a flat surface and a curved cavity that provides suitable support during placement on a component of mobile machinery to be serviced. The component can be a wheel and the cavity can be configured to allow for placement on substantially all wheel types and size.

  • Patent number: 4096749
    Abstract: A core sampling device of the type utilized in forming concrete test cores in situ including a double-walled sleeve which is placed into the wet, fluid concrete in combination with an insertion tool whereby the sleeve, due to its configuration, may be pressed or "screwed" into the fluid concrete. By virtue of the double-walled construction of the sleeve, once the concrete has cured, the test core may be easily removed therefrom.
