  • Patent number: 7059201
    Abstract: The present invention provides a pressure sensing device that includes at least one TMR sensor, and preferably an array of TMR sensors, with each TMR sensor having an insulating spacer layer interposed between a pinned and a free ferromagnetic layer. In an unbiased state, the magnetization vector of each of the ferromagnetic layers is preferably parallel to each other. Upon application of a small voltage, the magnetization vectors remain unchanged. Upon application of stress, the magnetization vector of the free magnetic layer will rotate, thus causing a corresponding and proportionally related change in the resistance of the sensor. This change in resistance can be sensed and used to calculate the stress applied thereto.

  • Patent number: 6881972
    Abstract: A media processing system retrieves a sheet of media and transports it to an imaging process. Misalignment of media from retrieving and transporting is removed by a media realignment process which wedges the leading edge of the media into stopped rollers while additionally advancing the trailing edge of the media for a predetermined distance. The media flexes and forms an arching buckle which aligns parallel to the leading edge of the media with the stopped rollers, thereby removing the skew of the media in relationship with the stopped rollers. The amount of over-advancement of the trailing edge of the media is modified according to the stiffness of the media. A media stiffness sensor measures the media stiffness by quantifying the deflection of the media when a portion of the media is cantilevered into deflection-measuring sensors. Imaging processes are also improved by employing media stiffness measurements to modify imaging processes.

  • Patent number: 6823744
    Abstract: A six-axis force sensor 1 consists of a sensor chip having a six-axis force sensor function formed using a semiconductor substrate 2 and film-forming technology. Connecting parts 5A to 5D are each made up of a high-rigidity bridge part and a low-rigidity elastic part. Semiconductor strain resistance devices Sya1-Sya3, Syb1-Syb3, Sxa1-Sxa3, and Sxb1-Sxb3 consisting of active layers are disposed on the front sides of the connecting parts. The elastic parts of the connecting parts absorb excess strains acting on the connecting parts and suppress the occurrence of strain spread over the whole semiconductor substrate. Because forces and moments of six specified axis components cause strains to occur selectively in corresponding strain resistance devices, by suitably combining measured results from selected resistance devices it is possible to effectively separate an applied external force into six components of force and moment and greatly suppress other axis interference in the measured results.

  • Patent number: 6725734
    Abstract: A rotation sensor functioning as both a rotation-angle sensor and a torque sensor is provided which, when applied to a steering sensor for an automobile, for example, permits reduction in the number of components and thus in the weight of the automobile and contributes to conservation of global environment. The rotation sensor has slip rings covered with conductive synthetic resin having small coefficient of friction, allowing the contact pressure of brushes disposed in sliding contact with the slip rings to be kept low and the life duration of the slip rings to be prolonged. Further, no metal powder is produced when the brushes slide on the respective slip rings, and it is therefore possible to prevent the formation of unwanted insulating film.

  • Publication number: 20030220766
    Abstract: Method and apparatus for identifying and categorizing the weight and characteristics of the occupant currently occupying a vehicle seat. The method for identifying and categorizing the occupant or object involves measuring the deflection of the upper surface of the seat cushion at several points and therefore the weight distribution of the occupant. The system contains multiple weight sensors arrayed for detecting the distribution of the load causing the seat deflection. The system also includes a sensor to measure ambient temperature, preferably for temperature compensation due to the effects extreme temperatures may have on the compression properties of the seat cushion material and the weight sensors. A system processor interprets the data acquired by the sensors, and utilizes an algorithm and weight tables to simulate a neural network in providing an output a control signal indicative of the categorization of the occupant or object.
