Filed: 1992-01-06
Abstract: A fast, accurate system for manufacturing holographic projection screens. The invention (10) includes a mechanism (28) for moving holographic film (26) along a longitudinal axis thereof in a first direction. A mechanism (12) is provided for directing and maintaining an input beam (22) onto the film (26) as the film (26) is moved.

The mechanism (12) for maintaining the input image at a fixed location on the film includes a polygon shaped mirror mounted to rotate at a rate determined in accordance with the rate of movement of the film. An image stabilization system (40) is also provided which includes a detector (58) for monitoring an interference pattern created by the signal beam and the reference beam. Circuitry (60) is included for providing control signals in response to the detector (58) outputs. A phase shifter (44) induces a phase shift in the reference beam. A phase shifter positioning mechanism (46) adjusts the phase shifter (44) in response to the control signals so that the image is stabilized on the film (26) despite the movement thereof.

Title: Switched reluctance motor position by resonant signal injection
Inventor: GOETZ JAY R
IPC: H02P25/08
Filed: 1992-02-04
Abstract: An apparatus is provided far estimating the position of a rotor of a commutated brushless motor operating without a shaft position sensor. The apparatus includes a tank circuit that incorporates a phase winding of the motor. A low-power signal of a frequency F1 is injected into the tank circuit. The frequency F1 is much greater than the switching frequency F s of the phase winding.     Because the effective inductance (L) of the phase winding incorporated into the tank circuit changes in a cyclic manner in response to changes in the mechanical angle .THETA. of the rotor, the characteristic resonant frequency F0 of the tank circuit varies between maximum and minimum values.      The effect of the variation of the resonant frequency F0 on the output characteristics of the tank circuit are used by a detection circuit to resolve the mechanical angle .THETA. of the rotor and, thereby, control the timing of the phase firing sequence. The two illustrated embodiments detect changes to the amplitude and phase, respectively, of the signal from the tank circuit in response to the changing inductance of the phase winding incorporated into the tank circuit.

Inventor: BLAIS FRANCOIS
IPC: G01S17/06
Filed: 1992-02-14
Abstract: An optical system for tracking a target scans an optical beam across the target in a Lissajous pattern.  The pattern has at least one portion that extends across the target. Return signals reflected from the target are used to calculate the range (and, if desired, also the intensity) of each measured point on the target (and beyond the target if some portions of the pattern miss the target), and to calculate the deviation of a reference location on the pattern, e.g. its center, from a selected location of the target.  This deviation is used to correct the scan to move the reference location on the pattern towards the selected location on the target, thus tracking the target.  The amplitude of the pattern can be changed to adjust the pattern on the target or to search for a target.  By virtue of the range data obtainable for points on the target and on edges of the target, the system can also determine other features, such as the shape, profile, identity and attitude of the target.
