Abstract: Disclosed is a system for detecting and displaying airplane and/or vehicular activity on an airport runway or its intersecting taxi ways and providing an indication of such activity to the crew of an on-ground aircraft operating upon or approaching the same active runway or taxiway. The system relies on a plurality of LCD, LED, or other electronic monitors which display a video image of the runway, taxiway, or intersection immediately adjacent to the location of the monitor. Any discernable aircraft or vehicular traffic operating on the subject runway or taxiway is displayed by icons (mechanical or electronic image) against the runway/taxiway background on the monitor. The monitor is powered by instantaneous feeds from any combination of all or a variety of sources, including ground control radar returns. Airport Surface Detection Equipment (ASDE-X), Automatic Dependent Surveillance-Broadcast (ADS-B), aircraft transponders, air traffic controller stations, satellite transmissions, and other equipment.

Abstract: For musicians playing an electric or acoustic guitar, there is disclosed a re-designed plectrum having an orthogonally-protruding handle and a snubber extending from the handle. The handle and snubber allow the plectrum to be inserted into the channel of a flexible, primarily longitudinal strap-retainer. The plectrum and strap-retainer, thus connected, form a one-piece handled plectrum assembly, with the strap-retainer being fastened about one, two, or three fingers of the user. The disclosed plectrum assembly provides an improvement in the gripping surface available to the user, in addition to providing more comfort and more reliable thumb and forefinger gripping orientation. The assembly also permits a rapid release of the plectrum for finger-plucking or strumming style of play.

Abstract: A device for playing a stringed musical instrument, comprising a tabbed plectrum with an enhanced feature, consisting of an extended gripping surface, or tab, which allows the attachment of a variety of grasping devices to the plectrum. Thusly, a musician is provided a secure and comfortable method for holding the plectrum while playing a stringed musical instrument. Both the plectrum and the grasping devices are used in conjunction with each other to facilitate the ergonomic playing of such instruments. Additionally disclosed is a method for the efficient movement of a musician's forearm and wrist muscles while playing a stringed instrument with the tabbed plectrum with any of the grasping devices.

Abstract: A plectrum with an enhanced design feature, primarily consisting of an extended gripping surface, or “tab,” said tab facilitating the attachment of a variety of grasping devices to the plectrum. A musician is thereby provided a secure and comfortable method of grasping and retaining the plectrum while playing a stringed musical instrument. Both the tabbed plectrum and the grasping devices disclosed are further used in conjunction with each other to facilitate the ergonomic playing of such instruments. Additionally disclosed are methods for the efficient movement of a musician's forearm and wrist muscles while utilizing the combination of a tabbed plectrum and grasping device during the playing of a stringed musical instrument.
