    摘要: A system and method of enhancing guitar instruction based on Tablature Plus encoding of playing techniques within a MIDI file or other data structure, that may be rendered on an associated player application that provides multimedia output of the piece being played including a number of playing techniques. The system hardware for encoding the information includes string motion monitoring, and optionally a hand motion and finger positioning sensor, such as a data glove or a video motion capture system, for simultaneously registering the actions of the guitarist while playing the piece. The software comprises algorithms for determining note pitch and duration, and for extracting playing techniques from the data being collected. Multimedia player software is also described which renders a visual and audio output for the Tablature Plus encoded file, wherein the encoded playing techniques are represented within the display output. The system is adaptable to instruction for any instrument.

    摘要: A device for generating a plasma includes an enclosed chamber and an antenna positioned adjacent the wall of the chamber. A ceramic shield is mounted on the wall, with the antenna located between the wall and the ceramic shield. There is also a barrier that is mounted on the wall with the ceramic shield being between the barrier and the antenna element. An alternating voltage source is provided to energize the antenna element to generate a plasma in the chamber. In operation, the ceramic shield isolates the antenna from the plasma in the chamber, and the barrier prevents the deposition of material components from the plasma on the ceramic shield.

    摘要: A long plasma formation tube is imbedded in a high magnetic field, with magnetic field lines passing axially through the tube, and with the tube being placed proximate or inside of a resonant cavity. Electromagnetic energy resonates in the resonant cavity representing stored microwave energy. The power density of the stored microwave energy is a function of the cross-sectional area of the resonant cavity. A portion of the stored microwave energy is concentrated to increase its power density, and coupled into the plasma formation tube, which tube has a smaller cross-sectional area than the resonant cavity. The coupled energy excites a whistler wave in the plasma formation tube that forms the plasma within the tube. In one embodiment, the stored microwave power is concentrated by funneling it through a metallic iris that forms one end of the resonant cavity, with a tip of the plasma formation tube being positioned near the metallic iris. In another embodiment, the plasma formation tube is positioned coaxially within the resonant cavity and the stored microwave energy is drawn into the plasma formation tube as plasma begins to form therein because the forming plasma represents a dominant power loss (load) for the stored energy.

    摘要: An adaptive DCPM video encoder operates directly upon a digitized composite video signal to generate a bit reduced serial digital output signal. The encoder has a feed back loop in the form of a recursive filter with zero's at d.c. and the color subcarrier frequency of the digitized encoded video signal that determines a predicted value for subtraction from the digitized composite video signal to produce a difference signal having the color subcarrier frequency nulled out. The difference signal is quantized to produce a quantized difference signal from which the predicted value is derived. An inner loop determines from the quantized difference signal an offset value from which the presence of large step transitions in the digitized encoded video signal are detected. For large step transitions the offset signal is subtracted from the difference signal to produce an offset difference signal for input to the quantizer. All adders and subtractors use modulo summing techniques to reduce the size of their outputs by one bit. The quantization transfer function for the quantizer is non-linear, having fine resolution near zero and coarse resolution away from zero. A plurality of quantization transfer functions are selectable according to the size of the step transitions as determined from the quantized difference signal. For digitized composite video signal samples near the maximum and minimum values when wrap around occurs due to quantization errors, a clip logic circuit selects a clipped quantized difference signal for output from the quantizer.
