Abstract: A method for manufacturing hemi-cylindrical and hemi-spherical micro structures is provided.

Abstract: An optical data storage medium includes a superstructure of micro-lenses defining first and second repeating periods. One of the periods is longer than the other, and the presence of the longer repeating period allows the medium to be used in an optical drive that is configured to use light diffracted by the longer period for tracking purposes. The micro-lenses may be configured such that adjacent lenses have different heights, widths, or shapes. In some embodiments, the spacing between adjacent data tracks is varied to provide the first and second repeating periods.

Abstract: An adaptive predictor for use with a control system to predict error contributions due to harmonic distortion in a error signal such that the prediction signal may be fed back and added to the error signal to compensate for the harmonic distortion. The adaptive predictor takes the error signal representative of misposition error and performs a discrete Fourier analysis to determine contributions due to individual harmonics. It then adjusts the results and tallies a running total thereby adapting to a mechanical system in which it is contained. The running total is combined with a carrier signal which is clocked to produce a predictive signal representing harmonic distortion at a given time. The predictive signal is then added back with the original error signal to produce a harmonic distortion compensated signal.

Abstract: In an electronic image printing apparatus of the type in which a light sensitive image recording layer is exposed by a light beam, an apparatus is provided for determining and controlling the position of the light beam which comprises one or two alternating pluralities of diffraction grating patterns disposed in a corresponding relationship with at least a portion of the light sensitive image recording layer to produce a diffraction grid which when irradiated by the light beam provides a diffracted beam which is representative of the position of the light beam on the diffraction grid. The position of the diffracted beam is detected to provide the requisite signal for controlling the position of the light beam.

Abstract: A preferred position detection system for accurate one-dimensional operation is realized using a diffractive encoder which provides two digital output signals 90.degree. out of phase. The two output signals correspond to relative movement between two objects. The diffractive encoder includes: a light source; a collimating lens; a mask; a diffractive grid; four photodetectors; and two comparators. Light from the light source is collimated through the collimating lens, selectively passed through the aperture in the mask, diffracted by the diffractive grid, sensed by the four photodetectors, then compared by the comparators to produce the two digital output signals which represent relative movement between the mask and the diffractive grid.

Abstract: An apparatus and a method are provided which can control an intensity level of an exposing device so that a desired pixel density is consistently disposed on a correct location on an image recording medium. Specifically, within a printing apparatus, even channel circuitry controls the intensity level of the exposing device during exposure of even numbered pixels on the image recording medium and an odd channel circuitry controls the intensity level of the exposing device during the exposure of odd numbered pixels on the image recording medium.

Abstract: A scanning system includes a scanner mirror driven in a substantially linear pivoting movement by a galvanometer excited with a substantially sawtooth current waveform, the mirror directing a pilot beam in a scanning movement along a photographic film located upon a diffraction grid which forms a part of a holder of the film. The film is transparent to the pilot beam, and is encircled by a frame defining a window for viewing the film. The grid is composed of a repeating sequence of groups of rulings oriented in different directions resulting in correspondingly different directions of the diffracted beam, upon illumination of the grid by the pilot beam. An array of detectors detects the direction of the diffracted beam, which is employed as a feedback signal to accurately locate the pilot beam, to provide fine position data of the pilot beam.

Abstract: A magnetic data storage system for use with a double sided disk in which a prerecorded pattern of opaque optical lines is used to define the tracks in which magnetic data is to be stored. A separate optical system including an illumination source and a photosensitive detector is provided on a read/write assembly for each side of the disk. Each detector is designed also to serve as a reference grating. The illumination source is designed to image the prerecorded pattern of optical lines on the reference grating as an indication of the alignment of the read/write head of the assembly and a desired data rack and any misalignment of the head and track generates a servo signal. The detector uses four separate photocells interleaved in a prescribed fashion to form a quadrature detector that is adjustable to compensate for various non-uniformities. One form of illumination source uses a surface-emitting light emitting diode and optics for forming a multiple beam source.

Abstract: A verification device has a transparent sheet including parallel rows of lenticules and rows of colored lines in registration therewith. Verification is accomplished by observing optical effects presented by patterns of irregularly positioned rows of lenticules and corresponding colored lines viewed against a surrounding background area of regularly positioned rows of lenticules and corresponding colored lines.

Abstract: A trajectory calculator receiving data indicating initial values of golf ball flight angle, velocity and spin, calculates the apparent elevation and deflection angles at which the golf ball would be seen by an observer at the launch point. An optical object projector projects an image representing the golf ball on a screen. The size of the image decreases with time to yield the apparent perspective size decrease with range. An optional exerciser console enables input of changeable environmental quantities.

Abstract: A video data acquisition system takes at least two snapshot views of selected points on a golf ball in the immediate post-launch time period. Analog video data are converted to digital data for analysis in an external system.A trigger generator, of a type well known in the art, senses the existence of a certain set of conditions associated with the launch of the golf ball and thereupon generates a set of precisely timed impulses which trigger the following sequence of events:(a) prepare TV camera to receive data(b) trigger first flash(c) trigger second flash(d) read out data from TV camera.

Abstract: A measurement system obtains and stores digital data on the positions of golf club and significant human body parts during a golf club swing. An interactive display allows later display of the measured performance for use in instruction or review. A coordinate transformer allows the viewing of a displayed simulated golfer from any aspect and at variable speeds and stop action. A generator such as an alphanumeric or graphic generator displays suggested display options, graphics, informative labels, and alphanumeric tabular data. Permanent copies of any displayed picture can be made for later home study.

Abstract: Electro-optical sensors measure the location of a plurality of spots on the surface of a golf club head or a golf ball at a minimum of two precisely spaced points in time. The two time points for the club head are just prior to impact with the golf ball. The two time points for the golf ball are just after impact by the club head. From the apparent displacements of the plurality of spots between measurements, the apparatus determines in substantially real time the velocity of the club head or ball and the spin about orthogonal axes.

Abstract: A photographic projection screen formed of separate parallel filaments having a center-to-center spacing equal to their diameters allows a projectile to be driven through it with minimal disturbance to image projected upon it.
