  • Patent number: 7383744
    Abstract: A seat belt tension sensor assembly including magnets oriented to reduce assembly size comprises a pull plate having portions defining a belt loop opening for receiving seat belt webbing and a sensor opening. First and second magnets are coupled to the pull plate on opposite sides of the sensor opening and are oriented with a first pole adjacent the sensor opening and second pole positioned away from the opening toward a side of the sensor assembly. A sensor disposed in the sensor opening is configured to provide an output in response to flux imparted thereto by the magnets. At least one projection extends from the sensor opening of the pull plate generally towards the sensor and is configured to direct magnetic flux from the magnets in a closed-loop path through the sensor. Upon application of tension to the seat belt webbing, the pull plate is configured to move along a first axis of the seat belt tension sensor assembly relative to the sensor.

  • Patent number: 7289041
    Abstract: An absolute position encoder for identifying which of a plurality of loci a moveable member occupies comprises a plurality of data tracks in which binary data is encoded to form a series of n-bit words, each of the plurality of loci being associated with one of the n-bit words. A plurality of the n-bit words is required to uniquely determine which of the loci the moveable member occupies. The absolute position encoder does not use a clock track to resolve the problem of asynchronous bit transitions.

  • Patent number: 7235765
    Abstract: A solar sensor that utilizes a blocking element and curved reflective element between the sun and a photo-sensitive electronic device to provide high signal levels and the ability to shape the angular response of the overall sensor. A particular angular response can be achieved by combining the attenuating affects of the blocking element with the increased response affects of the curved reflector. These two elements may be combined into one physical structure, or may be separate. Further, the present invention contemplates the use of multiple blocking elements and multiple reflectors.

  • Patent number: 7213482
    Abstract: An electro-mechanical actuator is provided that minimizes back drive effort by de-coupling the internal drive train of the actuator from the actuator output using a clutch. The clutch facilitates transfer of power to an output gear stage when the actuator motor is energized, but disengages the output gear stage when the actuator motor is de-energized. When the actuator output is manually operated, the clutch disengages the output gear stage, thereby reducing the number of gears that must be back driven by the manual actuation.

  • Publication number: 20060288968
    Abstract: The present invention includes a system and method for providing assurance and evidence that a particular part has been installed and properly maintained. In particular, automotive sensing systems may be incorporated into two-part sensor assemblies that are disposable within a vehicle. The sensor assemblies are adapted to provide evidence of tampering via mechanical, electrical and temperature-based means. In a preferred embodiment, the sensor assembly is disposed about an automotive heat exchanger and a plurality of thermal sensors measure the temperature of the heat exchanger. Any alteration in the orientation or placement of the sensor assembly causes a variance between the temperatures measured by the thermal sensors, which in turn provides clear indication of tampering to the driver.
