    摘要： An improved digital optical compact disc is disclosed which incorporates a further information storage element or area for storage and retrieval of track play selection information. The further storage area is comprised of defined information containing regions whose shading or alteration by the user indicates whether a corresponding track is to be skipped or played. An improved compact disc player reads the information containing defined regions and is capable of automatically selecting particular tracks for play. The information contained in the defined regions is stored in a format which is at-once visually-recognizable, machine-readable and manually-alterable.

    摘要： A light, such as a miniature flashlight, includes a housing adapted to hold a battery, a voltage step-up circuit disposed so as to come into electrical contact with the battery when the battery is placed in the housing and an illumination device, such as a light emitting diode (LED), electrically connected to the voltage step-up circuit. The voltage step-up circuit increases the voltage provided by the battery to drive the LED, to thereby enable the flashlight to use a power source, such as a single standard AA battery, which provides a DC voltage below the turn-on threshold voltage of the LED.

    摘要： A system and method for using a circuit for providing power from one or more battery packs charged by a AC-mains-provided electrical connection and which supply power to a hi-power, non-portable audio amplifier. The system includes a power supply sized to satisfy long time-basis average demands, a battery pack and with a controller which buffers or back-ends a power supply which is not otherwise capable of satisfying the variable load peak demands that an audio source imposes on the amplifier, while still maintaining a substantially constant battery charge over an extended period of time.

    摘要： A lighting fixture is slidably mounted on a track support which may advantageously be secured to any existing or available structure within or around the work space. In one preferred embodiment, it is secured to the side of a computer monitor which is either located on or adjacent to the work surface which is to be illuminated. The track support may be mounted on the computer monitor or other surface at any angle from vertical through horizontal thus providing a wide variety of options for an individual using the improved fixture of the present invention. The lamp fixture socket support is preferably rotatably mounted on a sliding car member which moves along the track support and also provides a first axis of rotation for the fixture. A reflector housing is also rotatably secured to the sliding car or fixture which thus provides a second axis of rotation for the fixture allowing greatest flexibility for positioning the lamp.
