The cork-pulling sleeve includes inner threads that mate with external threads on the neck of the bottle, and rotation of the cork-pulling sleeve in relation to the bottle extracts the cork.

Abstract: An on/off valve for a paintball gun comprises a valve body. The valve body includes a gas inlet to receive a gas from a compressed gas source and a gas outlet to transmit the gas to the paintball gun The valve body also contains a plug cavity for receivingly engaging a plug. The plug includes a flow aperture for transmitting the gas from the inlet aperture to the outlet aperture. An actuator controls the plug position and, hence, a supply of gas through the flow aperture. An o-ring is seated within an exit port of the gas inlet in contact with the valve body and the plug. In operation, the gas has a pressure that exerts a force on the o-ring to maintain it in a sealing engagement with the plug. Movement of the actuator between an “oi” position and an “off” position opens and closes the on/off valve. In an open position, the flow aperture is positioned in communication with the inlet aperture and permits a flow of gas from the inlet aperture to the outlet aperture.

Abstract: A first remote vocoder receives analog voice and produces packetized vocoder data which is transmitted over a wireless link. A first local vocoder receives the packetized vocoder data from the wireless link. The first local vocoder converts the packetized data to a multibit PCM output. The first local vocoder also adds a detection code to one of the least significant bits (LSB) of the PCM output. The first local vocoder passes the PCM signal to the PSTN from the second end user. The first local vocoder also receives PCM input over the PSTN. The first local vocoder constantly monitors the least significant bit of the PCM input for a detection code indicating that a second local vocoder is connected at the receiving end. If the first local vocoder detects the detection code from the second local vocoder, it begins to substitute packetized data and a redundancy check for a second one of the LSB's of the outgoing PCM. The first local vocoder also begins to monitor the second one of the LSB's of the incoming PCM.

Abstract: A method and apparatus for separating and removing distortion from interfering co-channel signals and suppressing adjacent-channel interfering signals of the Gaussian Minimum-Shift Keyed (GMSK) or other MSK type with filtering structures that exploit the cyclostationarity of the received GMSK or other MSK signals in order to accommodate a greater number (or the same number, but with greater quality) of transmitted signals received by one or more antennas than can be accommodated by existing filters. The parameters in these filtering structures are adapted by either of two adaptation apparatus that exploit both the known training sequence that is transmitted in most wireless communications systems, and the constant modulus property exhibited by each of the transmitted GMSK or other MSK signals.

Abstract: A sound environment control apparatus which allows a user, by operating a remote control unit, to selectively suppress any or all of multiple noises in his or her environment, or selectively listen to any of these while suppressing all other sound. One or more "primary" sound detectors are located in the user's sound domain to acquire all sounds that the user desires to hear as well as interfering sounds, and one or more "reference" sound detectors are placed at each interfering sound source that the user may wish to be able to control. Signals from the sound detectors are sent to a central processing unit/multiple sound controller where the interfering sounds are adaptively cancelled from the total audio provided by each primary sound detector or, when enhancement of a particular sound, rather than suppression, is desired, the audio from a reference sound detector is amplified and added to the total sound from the primary sound detector or used to replace the total sound from the primary sound detector.

Abstract: A method and apparatus for active cancellation of vibrational noise produced by a medical instrument in the head of a patient. Vibrations from the instrument, as well as vibrations in the bone structure in the head of the patient, are sensed and processed to generate cancelling noise waves which are then fed into the inner ear through vibrators placed on the head of the patient. An equalizer shapes the magnitude and phase spectrum of the vibrational signal picked up from the drill and delivers the equalized vibrational signals to the patient. An automatic adaptive controller adjusts the equalizer using control signals consisting of vibrations from the bone structure and the drill.

The carrier includes a main frame joined by a bottom frame structure to form the nacelle. Wheel assemblies are pivotally mounted on the main frame and may be attached or detached from the bottom frame structure for use or for storage.

Abstract: A processor and method for extracting or estimating directions of arrival of signals from a received data vector x(t) which has been corrupted by interfering signals and noise is described. The processor extracts signals by forming the scalar product of x(t) and a weight vector which is chosen such that the spectral self-coherence or conjugate spectral self-coherence of the processor output is maximized. The processor estimates the directions of arrival of signals by spectral self-coherence-selective performance surfaces for maxima.

Abstract: A method and apparatus for spatial multiplexing of spectrally overlapping communications signals which does not require use of a training signal, computationally intensive direction-finding methods, or antenna calibration is presented. An adaptive antenna array at a base station is used in conjunction with signal processing through self coherence restoral to separate the temporally and spectrally overlapping signals of users that arrive from different specific locations within the locale and to mitigate multipath fading and shadowing at the base station and, by reciprocity, to transmit directively to minimize interfering signals arriving at the mobile (or portable or stationary) units and to mitigate multipath fading and shadowing at the mobile units. The radiation pattern of transmitted signal is matched to the adapted reception pattern of the signal received at the base station.BACKGROUND OF THE INVENTIONThe Government has rights in this invention pursuant to Grant No.

Abstract: An improved powder delivery system for use in dispensing powder to a printing press. The improvements include an agitator system for the powder reservoir, a wiper block for use with a curved feed roller, a split air flow amplifier which is openable for cleaning, a flow-through rotary manifold for distributing powder to press and an improved powder spray block. The foregoing elements minimize the flow restrictions and enhance air and powder flow through the system. A control panel is provided at the operator's console which is remote from the mounting position for the powder delivery apparatus. The control panel provides for, among other things, the delivery of powder at a fixed rate regardless of press speed or in accordance with variations in press speed. For example, in accordance with a factory determined linear relationship or an operator entered relationship. Such data can be stored for future reference and use.

Abstract: An uninterruptible power supply derives regulated power from either a primary power source or a reserve power source. A power flow control unit derives the output power as needed from either one or both power sources. Its operating characteristics are selected so that complicated transfer and disconnect circuitry is eliminated.
