  • Optical input device
    Patent number: 7652563
    Abstract: One aspect is a device for displaying an indication of a system parameter. The device includes an input circuit, an optical sense circuit, a control circuit, and an output circuit. The input circuit is configured to receive input signals that are indicative of a measured system parameter. The optical sense circuit is configured to receive sense signals indicative of a sensed level of light and to receive programming signals related to a system parameter. The control circuit is configured to correlate the input and programming signals and to produce control signals dependant thereon. The output circuit is configured to display an indication of a system parameter that is based upon the control signals.

  • Wireless tram gauge assembly
    Patent number: 7275335
    Abstract: The present invention relates to a digital tram gauge assembly having an extendible elongate tram bar having a first height rod at a first end and a second height rod at a second end. A digital measuring device is positionable about the tram bar and is capable of digitally sensing, displaying and wirelessly transmitting measurement data from the digital tram gauge. The digital measuring device further includes a digital level sensor that functions as a digital level comparator to indicate whether the tram gauge assembly is oriented substantially parallel to a user-defined reference datum plane.
