摘要： A light emitter is disclosed herein. An embodiment of the light emitter comprises a tube, a first aperture, a second aperture, a lens, a base mechanism, and a light path. The tube has a first end and a second end. The first aperture is located proximate the tube first end and the second aperture is located proximate the tube second end. The lens is located within the tube. The base mechanism is attached to the tube first end and has a cavity formed therein. The light path extends between the cavity and the second aperture and passes through the first aperture and through the lens.

摘要： A motor driver high current protector includes a voltage source, a current sensor, a comparator, a switch, a delay circuit, and an inhibitor. The current sensor is configured to sense current passing through the motor driver and output a voltage responsive to the sensed current. The comparator has an output and is configured to generate a low voltage at its output while the output of the current sensor exceeds a first reference voltage. The switch has an input, an output, and a base. The base is activated by a low voltage at the output of the comparator to close the switch. Closing the switch provides electrical connection between the input and the output of the switch. The input of the switch is connected to the voltage source. The delay circuit is connected to the output of the switch and is configured to delay the voltage at the output of the switch while the switch is open. The delay circuit may include a resistor and a capacitor each connected to the output of the switch. The inhibitor is configured to inhibit the motor driver while the output of the switch exceeds a second reference voltage. The inhibitor may include first and second inhibitor comparators, each of the inhibitor comparators has an output. Each of the first and second inhibitor comparators is configured to generate a low voltage at its output while the output of the switch exceeds a second reference voltage.

摘要： A positioning apparatus and method for assembling the same on a rotating member. An embodiment of the positioning apparatus comprises an encoder having index markings indicative of the rotational position of the rotating member, a decoder for reading the index markings from the encoder when the encoder is mounted to the rotating member at a desired distance from the decoder to determine the rotational position of the rotating member, and at least one spacer for mounting the encoder on the rotating member at the desired distance from the decoder.

摘要： An autochanger has a plurality of media holding bays to hold media pieces. A light emitter and light receiver are placed within the autochanger to establish a light path adjacent the media holding bays. When the light path is disrupted an indication is provided that a media piece is dislodged from its media holding bay. The light emitter has a tube with a light source located adjacent an input end of the tube and a lens located adjacent an output end of the tube. The input end of the tube has a relatively small aperture to limit light passing into the tube and to the lens. The light emitter serves to provide pseudo-collimated light that illuminates a specific light receiver.
