Abstract: A ballistic resistant protective garment having a ballistic resistant pad which has at least three panels including a first panel constructed of a plurality of overlying layered sheets in which each sheet is constructed of a first type of high tensile strength woven fiber, a second panel constructed of a plurality of overlying layered sheets in which each sheet is constructed of lyotropic liquid crystal polymer material, and a third panel constructed of plurality of overlying layers of composite body armor material positioned at a body side of the pad in which the first, second and third panels are in overlying relationship to one another to form the pad. The employment of the panel of layered sheets of lyotropic liquid polymer fibers introduces a synergistic effect with the ballistic resistant materials of the other panels.

Abstract: A system and method to measure channel quality in terms of signal to interference plus noise ratio for the transmission of coded signals over fading channels in a communication system. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure for coherent and non-coherent transmission schemes. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes speeds. The filtered metric is mapped to the signal to interference plus noise ratio per symbol using a threshold based scheme. Use of this implicit signal to interference plus noise ratio estimate is used for the mobile assisted handoff in a cellular system, power control and data rate adaptation in the transmitter.

Abstract: A telephone with an automatic muting circuit that mutes the microphone in response to detection of speaking pauses of the local user to reduce noise due to acoustical feedback that are detected by comparing the waveforms from the microphone and the audio speaker after being amplified by amplifiers with automatic gain control circuits to the same level with speech subtractor. During pauses when the signals compared are substantially the same, then automatic muting circuit is activated by the speech subtractor to mute the microphone but when the local user speaks into the microphone the subtraction of the waveforms does not yield a null result and the microphone is unmuted.

Abstract: An automatic channel responsive television input source selection switch couples output signals from a selected one of a plurality of input television input source interface circuits to a television in accordance with a user channel selected with a user channel selector manually controlled through one of a remote control unit and interface and a manual interface. A look-up table memory stores each of the possible user channel numbers along with an associated input signal source channel and an indication of signal source identity, such as indication of a direct broadcast satellite television signal source, a public television broadcast source and a security camera source. The switch based on the associations stored in the look-up memory selects the associated video input signal source and provides an indication of the associated source channel number to a tuner included in the selected interface.

Abstract: An invalid mobile telephone call made within the service area of a vendor monitored by a vendor computer is detected by RF fingerprinting or the like results in transmission of a kill-call command over a TCP/IP network to a kill-call server that is interfaced with a mobile service center through a data link interface. The kill-call server determines whether the kill-call command is valid and, if so, then it transmits a message tear down request over the data link interface to an executive cellular processor which, if the kill-call capability is active, conveys a call termination message to the associated administrative call processing database node to effect the call termination.

The body is secured in a position relative to the electrical circuit component enabling the accelerated air stream to communicate with the thermal energy generated by the electrical circuit component.

Abstract: A system and method for echo cancellation in a communication system having a digital echo canceller and an analog echo canceller for analog reduction of cross coupling echo components in an analog output signal when in analog form before digital processing by the digital echo canceller. An analog cancellation signal is generated which is substantially the same as the acoustic coupling echo component in the analog output signal before digital processing by the digital echo canceller. The analog echo cancellation signal is combined with the analog output signal to reduce the cross coupling echo component before digital processing by the digital echo canceller.

Abstract: An annular insulator is positioned around a compliant contact section of a replacement contact pin for a header contact pin connector prior to insertion of the replacement contact pin through a header pin mounting hole and then both the replacement pin and the annular insulator being carried by the replacement pin are simultaneously pounded into snug received relationship within an associated pin receptor connector hole. A header contact pin repairing fixture has a plurality of size reducing holes for reducing the cross sectional dimension of the compliant section, one of which has an insulator end receiving opening for nesting receipt of a tapered wall at the end of the insulator to hold it in an upright orientation above and in alignment with the smallest sizing hole during insertion of the replacement pin into the insulator bore.
