  • Patent number: 6501458
    Abstract: An apparatus for transmitting a signal corresponding to a rotation of a spherical body. The apparatus includes a housing having an aperture, and a substantially spherical body having a first portion disposed within the housing so as to have a portion of the body disposed within the aperture, the spherical body operable to rotate within the housing. A first and second permanent magnets are disposed within the spherical body, and are operable to emit a magnetic field. A first magnetic sensing device is disposed within the housing, the first magnetic sensing device being operable to detect the magnetic fields and to generate a first output signal as a function of the strength of the magnetic fields. The first output signal is transmitted via a first conductive path coupled with the sensor.
    Type: Grant

  • Patent number: 4984133
    Abstract: An enclosure is provided for containing the logic elements and ancillary components for computing systems. The enclosure is a unitized central electronics enclosure (CEC) wherein the primary structural element is the enclosure for the logic elements. This enclosure or logic cage includes unitary side plates, a double-sided backplane and top and bottom cast guides. The integrated structural and enclosure functions accommodate the structural needs of a CEC, as well as containing and supporting the logic elements and ancillary equipment.
