摘要： A brushless DC motor employs a set of coils positioned around the motor axis to respond to an aximuthal pattern of changing eddy current sensitivity. Rf voltage is frequency-multiplexed on the motor power leads at a frequency that does not affect motor operation. Rf voltage measurement circuits located remotely from the motor respond to the changing coil impedance to generate signals representing the azimuthal position of the motor rotor, that control a set of commutation circuits.

摘要： A bearing arrangement for rotatably supporting a generally cylindrical journal having an outer circumferential surface exhibiting out-of-round deviations superimposed on a perfect cylinder that is centered on a longitudinal axis, with the journal acting on the bearing arrangement with a basic radial action force aimed along a reference half-plane extending in a predetermined radial direction from the longitudinal axis, includes a pair of bearing pads situated at respective contact locations that are spaced in opposite circumferential directions from the reference half-plane. Each of the bearing pads extends substantially over the entire length, but at most only over a small fraction of the circumference, of the outer circumferential surface, such that the bearing pads are at most in a very limited area contact with the outer circumferential surface when the journal is supported thereon. The circumferential spacing of the contact locations is by respective half-angles that are so selected in dependence on the character of the OOR deviations as to at least minimize the extent of vibrations of the journal in and opposite to at least one of the predetermined radial direction and a radial direction normal to the half-plane.

摘要： A method and system for automatically aligning a high power laser. The highower laser train includes an unstable resonator cavity and two turning mirrors to direct the pointing of the output laser beam. The autoalignment system is designed to perform two alignment tasks, the maintenance of output beam pointing stability and the establishment of resonator cavity mode control, by precisely adjusting the orientation of the end mirrors of the resonator cavity and the two turning mirrors. A HeNe laser, located at the output end of the high power laser train, propagates an alignment beam back along the laser train, parallel to the high power laser train. The alignment beam is divided into two separate alignment beams by means of a mirror splitter. One of the beams is directed on an optical alignment path which includes the two turning mirrors and is delimited by two null position detectors, one on an end mirror of the resonator cavity and one at the output end of the high power laser train. The other alignment beam is directed along the optical axis of the resonator cavity on an optical alignment path delimited by two more null position detectors, one on each of the two end mirrors of the resonator cavity. Since these two optical alignment paths include all the mirrors of the high power laser train, any misalignments in these mirrors will result in alignment beam deflections. The beam deflections are detected by the four null position detectors and translated, by means of an analog matrix control device, into corrective, correlative tilt adjustments to the mirrors of the high power laser train.

摘要： A commutator arrangement includes a commutator member rotatably mounted on a support and including a plurality of circumferentially adjacent contact pads that are mechanically connected with one another and electrically separated from each other by respective intervening gaps, and a number of commutator brushes that are mounted on the support for only substantially radial movements toward and away from the commutator member and are biased toward the latter to establish contact between their respective contact surfaces and those of the pads. The lateral edges bounding one kind of these contact surfaces circumferentially deviate from those delimiting the other contact surface kind over at least a part of their courses such that different portions of such lateral edges are juxtaposed with their counterparts at different times during the relative rotation of the commutator member.

摘要： An arrangement for chopping a collimated beam of light traveling in an initial path, includes a flexible mirror which reflects substantially all of the light from the initial path into an auxiliary path in a first configuration thereof. The flexible mirror is deformed by a magnetodistortive actuator from its first configuration to a second configuration in which it disperses the light reaching it in such a manner that all but a minute fraction of the dispersed light propagates outside the path. Further propagation of the light that is reflected by the flexible mirror to the outside of the auxiliary path along the auxiliary path is blocked by an aperture plate having an apeture through which all of the light reflected by the flexible mirror passes when the flexible mirror has its first configuration.

摘要： An arrangement for detecting the passage of living beings into and out of a surveillance region includes optics which concentrate thermal radiation energy from the surveillance region into a detection zone where an active area of a pyroelectric detector is situated and converts the thermal radiation energy received thereby into an electrical signal. An evaluating device evaluates the electrical signal of the detector to provide an indication of either the entry of a living being from the outside into, or the exit of a person from, the surveillance region from a change in the total thermal radiation energy received by the active area from the surveillance region. The optics may incorporate a mask which prevents thermal radiation from the outside of the surveillance region from reaching the active area of the detector. The mask includes a marginal portion which peripherally bounds an opening for the passage of the thermal radiation energy from the surveillance region to the detection zone and which may include at least one serration at the opening for controlling the timing of the electrical signal caused by entry of a living being into an area of the surveillance region corresponding to the serration relative to those caused by entry of a living being into the remainder of the surveillance region.
