摘要： A dynamic power amplifier advantageously employed in a wireless terminal for transferring and receiving signals from a base terminal includes an input amplifier adapted to receive an input signal having a given power signal level corresponding to the distance of said wireless terminal to the terminal and adapted to provide an amplifier output signal having a given power output signal level. The dynamic amplifier further includes a power sensor configured to receive the power output signal and to generate a power indication signal corresponding to the power output signal, and a converter adapted to receive the power indication signal in order to generate a biasing signal corresponding to the power indication signal. The biasing signal is applied to the input amplifier so that the operating bias point of the power amplifier varies as a function of the power indication signal.

摘要： A circuit that increases the efficiency of a radio frequency mobile telephone unit is disclosed. When the signal strength between the base station and the mobile unit is below a predetermined signal strength level, the power amplifier is turned on and the transmitter circuit of the mobile unit fully amplifies the RF signal. However, when the signal strength between the mobile telephone unit and the base station is above a predetermined signal strength level, the power amplifier is deactivated and bypassed from the transmitter circuitry, thereby conserving the battery power of the mobile unit.

摘要： An indoor wireless communications system using two-way active-antenna repeaters to distribute signals received from external signal sources within an office, and to extend the range of cordless phone units in use there, is disclosed. The repeaters provide menu-selectable phase-shifting, selectable receiver sensitivity and transmitter power, and selectable signal format conversion to provide added privacy and to prevent interference with communication links in use by third parties within the building. Pattern selection is done by empirical adjustment of an antenna pattern suited to the general floor plan of the area served.

摘要： In accordance with one embodiment of the present intention, an adaptive feedback controller is configured to substantially reduce an error control signal defined by the difference between a command signal and the output signal of a controlled device. The adaptive controller comprises a step generator circuit configured to provide a control signal which is employed to vary the input signal received by the controlled device, The control signal is substantially in the shape of a ramp signal having a given slew rate. An adaptive slew rate computation circuit is coupled to the step generator so as to provide a slew rate compensation signal to the step generator to increase the slew rate of the control signal, when the controlled device is responding to a substantially fast varying input signal. The slew rate compensation circuit decreases the slew rate of the control signal, when the controlled device is responding to a slow varying input signal.

摘要： A method and system for cancelling body movement effect for non-contact vital sign detection is described. The method begins with sending on a first electromagnetic wave transceiver a first electromagnetic signal with a first frequency to a first side of a body, such as a person or animal. Simultaneously using a second electromagnetic wave transceiver a second electromagnetic signal is sent with a second frequency to a second side of a body, wherein the first frequency and the second frequency are different frequencies. A first reflected electromagnetic signal reflected back in response to the first electromagnetic wave on the first transceiver is received and a first baseband complex signal is extracted. Likewise a second reflected electromagnetic signal reflected back in response to the second electromagnetic wave on the second transceiver is received and a second baseband complex signal is extracted. The first baseband complex signal is mathematically combined with the second baseband complex signal to cancel out a Doppler frequency drift therebetween to yield a periodic Doppler phase effect.

摘要： Exemplary embodiments provide a self-powered wireless gas sensor system and a method for gas sensing using the system. The system can be used to detect and constantly track a presence of various gases including hydrogen, ozone and/or any hydrocarbon gas, and remotely transmit the sensing signal. The system can include a low power gas sensor that consumes less than about 30 nano-watts of power. As a result, the system can detect the presence of hydrogen at about 10 ppm. The sensor can also provide a fast response time of about 1-2 seconds. In various embodiments, the system can be physically small and packaged with all components assembled as a single compact unit.
