  • Positioning System, Method, And Stage Serial Interface Board
    Publication number: 20190056710
    Abstract: Disclosed is a positioning system having at least one axis of movement and a serial interface board and method for use therewith. The system includes at least one controller and at least one positioning stage. The at least one positioning stage is in communication with the at least one controller and includes a first positioning stage. The first positioning stage includes a first carriage and a first motor configured to displace the first carriage along a first positioning axis or rotate the first carriage about the first positioning axis. The first positioning stage also includes a first serial interface that is configured to connect to a source of power and receive first-stage sensor signals from one or more stage sensors associated with the first positioning stage. The first serial interface is also configured to communicate at least a portion of the first-stage sensor signals to the at least one controller.

  • Calibrated encoder multiplier
    Patent number: 6501403
    Abstract: A device for receiving first and second analog signals consisting of two sinusoidal signals shifted in phase from an encoder and outputting digital pulses corresponding to the approximate number of equal steps the system of which the encoder is a part has advanced or retreated comprising flash memory storing a table relating total value counts to the precise value as previously determined by calibration and that adds or subtracts counts to or from a difference register so that the count in the difference register corresponds to the calibrated value moved by the system.
