摘要： A position sensor comprises a capacitive transducer and an inductor connected in series with the transducer. The transducer is a differential capacitor whose total admittance is essentially independent of changes in the sensed position. The total capacitance and inductance resonate at the fundamental frequency of a generator that provides a drive voltage and the resulting voltage across the sensor is thus substantially greater than the drive voltage. This increases the current through the transducer, and consequently increases the sensitivity of the sensor.

摘要： A reciprocating rotary action actuator consisting of a rotor and stator that can be added to a bi-directional rotary motor or galvanometer scanner, where the stator has a ring magnet and a pair of soft iron pole pieces that concentrate the flux of the ring magnet into a concentric set of narrow, uniformly spaced, axially oriented, magnetic flux fields intersecting the rotor's field of travel. The rotor has small permanent magnets embedded in the periphery of a nonconductive, nonmagnetic rotor core. The rotor magnets have the same number and spacing as the stator's magnetic flux fields. The magnet poles are oriented opposite the flux fields of the stator pole pieces, so that upon rotation, the rotor magnets encounter the stator flux fields at each end of rotor travel, creating an opposing force that reverses the angular direction of the rotor with minimal requirement for actuator current and generation of thermal losses.

摘要： A capacitive sensing system for detecting the angular position of a rotatable member of a motor. The position detection system includes a cylindrical excitation pin attached to the housing of the motor and a tubular signal plate, having a plurality of sensing surfaces symmetrically arranged about the axis of rotation of the rotatable member, which surrounds the cylindrical excitation pin and, which is also attached to the motor housing. A lobed dielectric is attached to the rotatable member of the motor and inserted between the cylindrical excitation pin and the tubular signal plate. An electric circuit connected to the sensing surfaces of the tubular signal plate calculates the relative angular position of the rotatable member from the amount of energy detected at each of the sensing surfaces.

摘要： A limited rotation motor optical scanning system is disclosed that includes a limited rotation motor scanner, a digital controller servo system, a position feedback unit, a wide angle compensation unit, a digital processor, and an adjustment unit. The limited rotation motor scanner element is adapted for directing an energy beam to at least one location within a field of view. The digital controlled servo system is adapted for controlling motion of the limited rotation motor scanner element in accordance with a servo command waveform. The position feedback unit is for providing a position feedback signal indicative of a rotational position of the limited rotation motor scanner element. The wide angle compensation unit is for receiving the position feedback signal and for providing a boost signal that is representative of a boost factor that compensates for torque constant variation with the rotational position of said limited rotation motor scanner element. The digital processor is for providing a set of control parameters for use during the command waveform in conformance with which the command waveform will be employed to control motion of the limited rotation motor scanner element. The adjustment unit is for providing an adjusted output signal responsive to the control parameters and responsive to the boost signal to control the motion of the limited rotation motor scanner element while compensating for torque constant variation with the rotational position of the limited rotation motor scanner element during the command waveform.

摘要： The invention provides a method and apparatus for directing a radiation beam (504, 606) in a desired direction. There is provided a movable member (10) supported for movement by a fixed member (40) and the movable member has an optical element, e.g a flat mirror (30) fixedly attached thereto. In one embodiment the mirror scans a radiation beam incident thereon in one plane. In a second embodiment, the radiation beam is scanned in two mutually perpendicular planes. A magnetic element (50) having a north and a south magnetic pole is fixedly attached to the movable member (10). A magnetically permeable stator element (70) that is stationary with respect to the movable member (10) and the magnetic element (50) is placed in the field of the magnetic element such that the stator element and said magnetic element mutually generate a magnetic traction force between them. A current coil (60) is wound around a portion of the stator element (70) and a current driver (400) is provided for driving a current in the current coil (60). The current induces an electromagnetic force in the stator element (70) and the electromagnetic force acts on the magnetic element (50) for controlling movement of the optical element (30) with respect to the fixed element (40). A radiation beam source (502) may be directed onto the movable mirror surface (30) and scanned by the movement of the mirror to direct the radiation beam in a desired propagation direction. Alternately, a radiation source (604) may be attached to the movable member (10) and pointed in a desired direction.
