摘要: A rotary positioning system includes a prime movement device having a plurality of windings spatially distributed to cause a rotor to assume, upon commanded energization of the windings, different ones of discrete angular positions. The system also includes a temperature variable power supply which compensates for the rotor's temperature-dependent variation in damping.

摘要: An automatic digital light source adjustment procedure is disclosed wherein a computer calculates a correction factor for each of a plurality of light sources and adjusts the light sources such that each of the light sources meets an optimum performance criteria. In one embodiment, a multicolor cathode ray tube is converged automatically utilizing the present invention by sensing the profiles of the amplitudes of the individual color light intensities versus the same light source position relative to the sensor mechanism for each of the three primary colors, calculating the correction factor and inputting the correction factor to a digital memory, and then providing for the correction factor to be applied to the analog output of the beam control thereafter. Alternative embodiments enhance focus, purity, light line width, color composition, and other performance factors. The sensor, in one embodiment, senses the speed of the relative motion between the light and the sensor, as well as simultaneously sensing the amplitudes of the individual colors.
