摘要： La invencion se refiere a un método para sincronizacion mutua del codificador vocal del transmisor y del decodificador vocal del receptor en un sistema de comunicacion que utiliza transmision discontinua entre el transmisor y el receptor. La transmision discontinua comprende periodos de bloques secuenciados temporalmente, algunos de cuyos periodos contendrán bloques transmitidos y algunos periodos no contendrán transmision; por lo cual el método contiene etapas para generar periodos de transmision de informacion (200) que comprenden al menos un bloque y que contiene informacion dada por un usuario a dicho dispositivo transmisor, y periodos de silencio (208, 209) que tienen una duracion de al menos el periodo de un bloque y que contiene informacion distinta a la dada por el usuario. La transmision discontinua comprende adicionalmente un periodo (T) que ocurre irregularmente, que comprende entre el periodo de transmision de informacion (200) y el periodo de silencio (208, 209) siguiente al menos un bloque, formando este periodo irregular un periodo de espera para determinar la informacion relativa al periodo de silencio. En el método de acuerdo con la invencion, el numero de periodos de bloques se contabliliza en el receptor hasta un cierto instante; se detecta el comienzo de dicho periodo de silencio (208, 209); y en base a dicho numero contabilizado de periodos de bloques y al comienzo del periodo de silencio (208, 209) se decide si existe o no un periodo de espera (T) de dicho tipo entre dicho perido de transmision de informacion (200) y el periodo de silencio (208) siguientes al periodo de transmision de informacion.

摘要： A record identification technique includes transmission of a record or audio track in conjunction with identifying or descriptive information in a combined voice and data radio signal. A receiver (14) stores temporarily the identifying or descriptive information. In response to activation of an identify button (460) by the user during a song play, the identifying information is stored in association with a segment of the audio track. The user later activates a review button (462) to listen to stored identifying information in conjunction with the associated stored segment of the audio track of interest. The user thereby more conveniently identifies a given record or audio track both audibly and by use of supporting identifying information.

摘要： An improved remote control system adapted for use with consumer appliances and the like and having improved frequency stability and relatively low cost comprises a ceramic-stabilized r.f. hand-held remote transmitter unit operating in conjunction with a ceramic-stabilized r.f. receiver unit (50) located within the appliance to be remotely controlled. The hand-held transmitter unit includes a negative resistance oscillator which comprises a ceramic resonator and an associated active element and is linked through a suitable matching network to a loop antenna for broadcasting r.f. signals therefrom. Modulation of r.f. signals at the oscillator is accomplished by ON-OFF keying of a switch linked to the oscillator. The remote receiver unit (50) includes an antenna (52) for receiving the broadcast r.f. signals and an associated isolation amplifier (54) for improving signal spectrum radiation and increasing power gain. The remote receiver unit (50) is implemented in the form of a super-regenerative receiver using a self-quenched r.f. oscillator (56) in which the frequency reference is derived from a ceramic resonator tuned to the reference frequency in the transmitter unit.

摘要： An improved proximal cable-less communications system using at least two receivers is described. The system is significantly improved by eliminating the sidetone which can occur in full duplex systems. Components are placed in the receivers, between the mixer components (710, 770) and the components which detect the information encoded in the signal at the intermediate frequency (800), which function to cancel out the detrimental affect of those signals containing information derived from the modulation of the local oscillator (610) of the receiver device.

摘要： The invention relates to an adaptive radio receiver apparatus suitable for use in a base station or a mobile telephone in a telecommunication system or a telecommunication system having radio in the local loop. The radio receiver is controllable for optimising operating parameters of the amplification circuits included in the receiver, in dependence of the traffic situation in which the receiver is located. The radio receiver in accordance with the invention utilises controllable amplifiers and adaptive control logic for controlling the operating parameters. The receiver apparatus comprises at least one controllable amplifier stage which is under control from a control unit for varying the operating parameters of the amplifier stage in dependence of the environment. The amplifier stage preferably includes a controllable low noise amplifier and a variable attenuation attenuator. Preferably the receiver apparatus has the capacity of controlling the operating parameters such as the blocking level, the intercept level, the sensitivity, the noise figure, the power consumption and the gain. The control unit comprises control logic for forming combinations of the operating parameters, each combination corresponding to a specific traffic situation.

摘要： A selective call receiver (100) includes a radio frequency amplifier (202) having an output power level that is controllable. A radio frequency level sensor (500) generates a sensor output signal in response to an input signal level received at the radio frequency amplifier (202). The sensor output signal is conditioned by a filter (401, 402) to generate a control signal representing an effective value of the input signal level received at the radio frequency amplifier (202). The control signal is then coupled to an amplifier output power level adjustment circuit (403) that operates to adjust a power gain of the radio frequency amplifier (202) in an unconditionally stable feed-forward manner such that the output power level remains substantially constant when the input signal level sensed by the radio frequency level sensor (500) substantially reaches or exceeds a predetermined signal overload level.

摘要： A detector (10) which senses the presence of ultrasonic energy and supplies humanly perceptible information representative of the magnitude and frequency. The detector (10) includes a transducer (20) which senses ambient ultrasonic energy and generates a signal (21) which is fed to an amplifier (22), filter (24), and attenuator (28) to produce an output signal (29) having an ultrasonic detected component and a noise background component. The signal (29) is fed through an amplifier (66) to produce an offset signal (67) which is fed to a differential amplifier (84). The same signal (29) is fed through filters (70, 72) and a peak detector (76) to the differential amplifier (84), which produces a noise compensated envelope signal (87). The frequency of the envelope signal (87) is converted to the audio range by a modulator (98) to produce a combined signal (99) having the frequency and intensity characteristics of the ultrasonic energy. This signal is amplified (102) and fed to an audio loudspeaker (104).

摘要： A selective amplifier adapted to exhibit uniform gain characteristics over the entire band of a frequency to be amplified without deterioration of signal-to-noise ratio. The amplifier includes an amplifying element (AMP) and a bandpass filter (BPF). A resister for removing ripples in the transmission characteristics of the filter serves as a feedback resister (Rf) for the amplifying element (AMP). Further, a coil (LB) in a parallel resonant circuit (CB, LB) of the filter (BPF) and a capacitor (CA) in a series resonant circuit (CA, LA) of the filter are composed of, respectively, a boosting transformer and the capacitance of a capacitive antenna, thereby improving signal-to-noise ratio. The amplifier is suitable for use in the first high frequency stage of a radio receiver.
