  • Patent number: 8773450
    Abstract: Arrangements and methods are provided that modulate various display device outputs in response to detected changes in environmental conditions affecting a display screen. The arrangement responds to changing environments to maximize the quality of the display. A sensor that is responsive to the changing environment, such as changes in ambient light, is provided to modulate the display accordingly. The arrangement contains logic for utilizing the sensing input and user preferences to provide the best display under the prevailing conditions.
    Type: Grant

  • Patent number: 7874819
    Abstract: A tube is provided for use in a peristaltic pump, with the tube including a cylindrical wall defining a hollow interior and a cylindrical outer surface. The tube further includes a longitudinal centerline axis and a plurality of indicia applied to the cylindrical outer surface, with the indicia including first and second indicium extending transversely to the longitudinal centerline axis. The second indicium is longitudinally spaced from the first indicium by a predetermined distance.

  • Patent number: 4865144
    Abstract: A closed-loop torque demand power steering system suitable for large off-highway and other vehicles has no mechanical linkages or hydraulic connections entering into the driver's cab. A torque demand signal is produced electronically without any separate electromechanical torque sensor. Upon starting, the system provides synchronization between steering and steering wheels without initial corrective motion of either member. During operation the direction of the steered wheels does not drift relative to the position of the steering wheel. The circuit includes protection against spurious steering signals that might otherwise occur if the steering is moved back and forth mechanically on a transition boundary of a position sensor. In the event of certain types of failure of its primary steering system it automatically changes over to an open-loop secondary steering system that is controllable by the same steering wheel, and that has components in common with the primary system.
