Title: Systems and methods for random access in time division multiple access satellite radiotelephone communications
Inventor: MASSINGILL LARRY W
IPC: H04B7/15
Filed: 1997-04-03
Granted: 2002-06-25
Abstract: In a time division mutiple access (TDMA) satellite radiotelephone communications system, a radiotelephone communicates random access channel radiotelephone communications signals to a satellite over a dedicated random access channel uplink carrier frequency band. In response, a time division mutiple access channel on a time division multiplexed uplink carrier frequency band different from the dedicated random access channel uplink carrier frequency band is assigned. The radiotelephone communicates time division multiplexed radiotelephone communications signals to the satellite over the allocated time division multiple access channel. Random access channel radiotelephone communications signals may be communicated to the satellite from a first radiotelephone over a first dedicated random access channel uplink carrier frequency band or from a second radiotelephone over a second dedicated random access channel uplink carrier frequency band different from said first dedicated random access channel uplink carrier frequency band. For a system in which the satellite communicates radiotelephone communications signals to radiotelephones located in a first coverage area and communicates radiotelephone communications signals to radiotelephones located in a second coverage area, random access channel radiotelephone communications signals may be communicated over a first dedicated random access uplink carrier frequency band if the radiotelephone is located in the first coverage area or communicating random access radiotelephone communications signals over a second dedicated random access channel uplimk carrier frequency band different from the first dedicated random access uplink carrier band if the radiotelephone is located in the second coverage area.

Abstract: The present invention relates to a drill string diverter apparatus for reducing surge pressure when lowering a liner into a partially cased wellbore. The diverter apparatus is connected in a pipe string above a liner being lowered into a wellbore. The diverter apparatus comprises a tubular housing with ports defined therethrough to communicate and redirect fluids received in the liner to the annulus between the diverter apparatus and casing previously set in the wellbore.      The diverter apparatus has an open position whereby the ports are open and communication is established and a closed position whereby flow through the ports is prevented. A sliding sleeve is disposed about an outer surface of the tubular housing and engages the casing. The sleeve moves vertically relative to the tubular housing once the diverter apparatus has been lowered into the casing to selectively open and close the flow ports. A J-slot means is provided for locking the diverter apparatus in its closed position.

Abstract: A pulsed power amplifier apparatus and method, for amplifying a pulsed signal, has an input for a pulsed signal; usually this will be a continuous wave RF signal that has been passed through a switch unit to form a basic pulse train. A splitter is connected to the input and has two outputs, for splitting the signal into two subsidiary signals. First and second branches are connected to the outputs of the splitter, each branch being for one of the subsidiary signals. First and second adjustable phase shifters are located in the first and second branches. A combiner is connected to the first and second branches and has an output forming a final output of the apparatus, whereby adjustment of the phase shifts effected by the first and second phase shifters affects the amplitude of the signal at the final output of the apparatus. Rapid variation of the phase shift within each pulse can be used to give a desired pulse shape.

Abstract: The process to which this invention relates is used to manufacture cylindrical sections from tubes, preferably of glass, for use in particular as syringe cylinders. The tubes are first withdrawn from the supply station and are then transferred individually to the processing station . There the tubes are held in such a manner that they can be moved axially forward and rotated about their axis, so that cylindrical sections can be sequentially cut from them by means of a laser. After each section is cut off, it is moved axially forward away from the tube. The opposing end surfaces of the tube and the section are simultaneously or serially melted to form a bulge or lip. Finally, the sections are conducted by means of guiding devices to the transportation unit, which is equipped with receptacles that have low heat-conducting properties, so as to avoid the occurrence of any mechanical stress in the sections as they cool, while the tube is moved forward for removal of the next section.

Title: Echo canceller employing dual-h architecture having variable adaptive gain settings
Inventor: LABERTEAUX KENNETH P
IPC: H04B3/23
Filed: 1998-11-13
Granted: 2008-01-15
Abstract: An echo canceller circuit for use in an echo canceller system is set forth that provides sensitive double-talk detection. The echo canceller circuit comprises a second digital filter having adaptive tap coefficients to simulate an echo response occurring during the call.  The adaptive tap coefficients of the second digital filter are updated over the duration of the call using a Least Mean Squares process having an adaptive gain a. A channel condition detector is used to detect channel conditions during the call. The channel condition detector is responsive to detected channel conditions for changing the adaptive gain a during the call. For example, the channel condition detector may detect the presence of a double-talk condition and set the adaptive gain a to zero. Similarly, the channel condition detector may detect the occurrence of a high background noise condition and set the adaptive gain a to a level less than 1 that is dependent on the detected level of the background noise. Other similar channel conditions and corresponding adaptive gain settings may likewise be utilized.

Abstract: A system for sensing subterranean acoustic waves emitted from an acoustic source includes a plurality of laser sources, a plurality of subterranean optical sensors, at least one optical detector, and electronics. The laser sources each emit light at a different frequency. The subterranean optical sensors receive the light and alter the light in response to the acoustic waves. The optical detector receives the altered light and outputs an electrical signal. The electronics receives the electrical signal and converts it into seismic data format. Preferably, the light emitted from the optical sources is modulated at a plurality of modulation frequencies. The electronics can be used to demodulate the signal. The electronics may demodulate the electrical signal by mixing the signal with periodic waveforms having frequencies corresponding to the modulation frequencies and twice the modulation frequencies. The modulation frequencies are selected such that at least one of the second harmonic frequencies associated with the modulation frequencies is interleaved in a non-interfering manner within the corresponding set of first harmonic frequencies. Preferably, the modulation frequencies are selected such that at least one of the first harmonic frequencies is interleaved in a non-interfering manner within the corresponding set of modulation frequencies. The hydrophone for sensing the acoustic signals is able to operate at pressures of at least 5,000 psi and temperatures of at least 130 degrees Celsius. The hydrophone may be housed in a cable having a diameter of less than about 1.5 inches. The hydrophone's sensor preferably includes a reference mandrel, two sensing mandrels, and a telemetry can, all of which are aligned in a coaxial, end-to- end configuration to reduce the profile of the hydrophone. Flexible interlinks having grooves therein for receiving optical fiber join the mandrels together. The reference mandrel and sensing mandrels advantageously have hemispherically-shaped endcaps, permitting them to operate at high pressure.
