  • Patent number: 5754688
    Abstract: A method and apparatus for analyzing two-dimensional structures to obtain three-dimensional quantitative information therefrom includes a video camera, a digitizing board for transforming video image output signals from the video camera into digital data, and a computer for analyzing the digitized video image data. Regions of interest or desired objects in the video image corresponding to the video image data are observed by an operator. Thresholding commands are supplied to the computer instructing the computer to manipulate the digitized video image data to enhance or distinguish the regions of interest from other areas in the video image. Once sufficient thresholding is accomplished, the computer executes an algorithm that identifies the regions of interest, draws a solid line around them, and sets all of the video image data defining each region of interest bounded by a solid line to a predetermined threshold value.

  • Patent number: 4614901
    Abstract: A servo power amplifier for driving multiple DC motors (10, 12) employs a load equalization circuit (36) which allows reduction of the overall number of circuit components required to drive the motors. The load equalization circuit is coupled in parallel with each of the motor drive circuits (14, 16) across the power source (46, 48) and controls an inductive load (84) which temporarily stores energy that is returned to the power source from the motors. The equalization circuit is pulse width modulated in accordance with a control signal which is derived by sensing the current flowing through the inductive load and using a sensing circuit (44) to determine the difference in the magnitude of the positive and negative voltages supplied by the power source. The equalization control circuit and the motor drive circuits are each T-configured and employ no more than two switching elements for controlling current flow.
