摘要： A laser light projector includes a laser beam generated by a laser light source, a scanner associated with the laser light source and having one or more moving mirrors capable of scanning the laser beam along X-Y coordinates, a scan-fail monitor and a safety-lens. The safety-lens includes at least one optical power, and is positioned and arranged for increasing the safety of the projected light within audience areas by increasing beam divergence in the audience, while keeping beam divergence low above the heads of the audience, thus allowing mirror targeting to occur.

摘要： An electromechanical rotary actuator includes a rotor and a stator having one or more slots into which one or more coils are placed. The stator includes a rotor position restoring means which overcomes cogging outside a desired rotation range. The rotor position restoration means may include one or more restoring magnets or optionally include a contoured cavity within the stator proximate the rotor. One stator includes teeth having contoured ends forming a portion of the aperture within which the rotor operates. Distal ends of the teeth form a relatively large gap compared to typical actuators, wherein the gap is sized to the rotor magnet. An actuator desirably having a high torque constant, low coil resistance and a low coil inductance is provided.

摘要： A rotary position detector includes a housing having an inner space having a reflective element therewithin. A light source emits light rays upwardly. A base supports a light detector assembly having a first number of toroidal-sector-shaped light sensors disposed in pairs about a motor shaft axis, one “A” detector element and one “B” detector element alternately disposed. A light blocker rotates with the shaft above the light detector assembly and the light source and includes a second number of opaque, equal-surface-area elements arrayed about the axis, the second number equal to one-half the first number. A circuit measures a signal from the “A” and “B” detectors relating to an amount of light falling thereon, a difference related to an angular position of the motor shaft.

摘要： A rotary position detector includes a housing and a light source positioned to emit light rays onto a light detector assembly having a first number of toroidal-sector-shaped light sensors, which are disposed in “A,B” pairs about a motor shaft axis so that each “A” detector is circumferentially positioned between two “B” detectors. A light blocker is affixed for rotation with a motor shaft between the light detector assembly and light source and has a second number of opaque, pie-shaped elements arrayed about the shaft, the second number equal to one-half of the first number. An angular subtense of the light blocker elements is greater than that of a detector element. A signal connection between the light detector elements and a circuit measures a signal from the “A” and “B” detectors relating to an amount of light falling thereon, a difference therebetween related to an angular position of the shaft.

摘要： A scanning mirror includes a reflective surface having a preset width dimension measured orthogonally to its axis of rotation. The preset width dimension accommodates a maximum angle of incidence of a beam being scanned by the reflective surface. A length dimension of the reflective surface, as measured along the axis of rotation, is at least equal to a diameter of the beam being scanned. A bottom portion of the reflective surface has an effective width dimension greater than the preset width dimension, and a top portion of the reflective surface has an effective width dimension less than the preset width dimension, such that a greater inertia is provided to the bottom portion of the scanning mirror that to the top portion. One shape for the reflective surface comprises a trapezoid.

摘要： An electromechanical device includes a rotor and a stator, wherein the stator includes multiple teeth excitable by a coil. The stator is formed from multiple stator sections with one section having a protrusion in spaced relation with a first tooth and a second section having a second protrusion in spaced relation with a second tooth. The protrusions have voids for receiving opposing protrusions in an overlapping manner to integrally form the first stator section with the second stator section. The electrical coil is extended around at least a portion of one tooth before mating the multiple stator sections. The rotor has a diametral magnetized magnet extending into the aperture.

摘要： A fault protector for an opto-electronic device includes a MOSFET having an integral body-diode. A capacitor is connected between a drain and a gate of the MOSFET, and a resistor is connected between the gate and a source of the MOSFET. The drain of the MOSFET is connectable to a first terminal of an opto-electronic device, and the source of the MOSFET is connectable to a second terminal of the opto-electronic device. The device overcomes problems of previously known techniques by preventing a reverse-bias voltage from exceeding an absolute maximum specified by a manufacturer, and also prevents ESD or other power-related faults from exceeding the maximum forward-bias voltage of the laser diode, while not adding significant resistance or capacitance to the laser diode, thereby not complicating the task of driving the laser diode.

摘要： An apparatus for rapidly varying the spot size of a scanned imaging laser beam comprises a focusing device (e.g. focussing and collimating lens arrangement) and a beam displacement control device (e.g. a rotary actuator scanner mirror or linear actuator). The beam displacement control device is operative to cause relative displacement between the laser beam and a selected one of a plurality of reflector element positions. Respective ones of the plurality of reflector positions are located at respectively different separation distances from the focusing device. As a result, in the course of traveling along an laser beam path, the laser beam is incident upon the focusing device and the reflector element, so as to be directed to a given spatial location along the path, whereby the laser beam has a resultant beam width that is dependent upon the separation distance between the selected reflector element position and the focusing device.
