    摘要: In heating and cooling apparatus, molecules of working gas are excited by light irradiation and thereby cooled as the gas flows through a mirrored cooling cell. In a closed loop embodiment, the gas then flows by means of a fan or compressor to a first heat exchanger where heat from the matter being cooled is transferred to the gas; and, then to a second heat exchanger where heat is transferred from the gas to a heat sink. The apparatus may be used either like a heat pump or air conditioner. In an open-end cooling apparatus embodiment, the gas flows from the cooling cell, through the first heat exchanger, and to atmosphere. The light source may be a 10.6 micron laser; or a 9-11 micron electric arc, a hot filament or the Sun. Working gases comprise N2 and C02; exhaust gases of engines or fuel cells; and gases which comprise different molecular composition gases or different isotopic species of the same molecular composition gas.

    摘要: The present invention is a method of finding range and velocity of a target in a radar system using a time scale factor. Specifically, sending at least one signal from at least one transmitter to a target. A return signal is then received from the target at each transmitter and the elapsed time is recorded. The range to the target and velocity of the target are calculated based on a time scale factor of the recorded elapsed times. These values are appropriately output to the user.

    摘要: Remotely-adjustable support apparatus and methods are disclosed. In one embodiment, an apparatus includes a primary support and a secondary support moveably coupled to the primary support. The secondary support includes a cradle member adapted to engage the workpiece. The apparatus further includes a drive assembly operatively coupled to the secondary support and adapted to move the secondary support relative to the primary support. A control device is remotely positionable with respect to the drive assembly and operatively coupled to the drive assembly. The control device is adapted to transmit at least one control signal to the drive assembly to move the secondary support relative to the primary support.

    摘要: The present invention is a device for and method of detecting voice activity by receiving a signal; computing the absolute value of the signal; squaring the absolute value; low pass filtering the squared result; computing the mean of the filtered signal; subtracting the mean from the filtered result; padding the mean subtracted result with zeros to form a value that is a power of two if the result is not already a power of two; computing a DFFT of the power of two result; normalizing the DFFT result of the last step; computing a mean of the normalization; computing a variance of the normalization; computing a power ratio of the normalization; classifying the mean, variance and power ratio as speech or non-speech based on how this feature vector compares to similarly constructed feature vectors of known speech and non-speech. The voice activity detector includes an absolute value squarer; a low pass filter; a mean subtractor; a zero padder; a DFFT; a normalizer; and a classifier.

    摘要: A three wheeled carriage supports an air compressor, a container for reflective glass beads and a primary hose enclosing secondary hoses delivering plural paint components to a spray gun. The three wheeled carriage has a handle bar operable by one person with three switches, one to control the flow of reflective glass beads to a bead spray gun, another to control the flow of paint components to form a stripe by external mix of the paint components and a third to control an angle of turn for a front wheel. A trailer follows the three wheeled carriage, the trailer containing an air compressor and receptacles for two paint components and input into the secondary hoses. Wheeled dollies support the primary hose between the trailer and the three wheeled carriage.
