An in-vivo sensing system including an in-vivo sensing device, a data recorder a receiver and a work station. The data recorder receives data signal from the in-vivo sensing device during an acquisition period. Batches of the data signal may be transmitted from the data recorder to a receiver, as soon as a batch has been received by the data recorder. The batches of data signal received by the receiver may be downloaded to the workstation as soon as each batch is received by the receiver. Signals are typically transmitted from the data recorder to the receiver through wireless transmission techniques such as cellular transmission, WLAN (Wireless Local Area Network) transmission, BT (BlueTooth) transmission and Wimax (Worldwide interoperability for Microwave Access) transmission.

Data recorder, system and method for transmitting data received from an in-vivo sensing device

Circuitry for providing improved pulse-type enhancement of the voltage supplied to a power amplifier () that is fed by a power supply that is connected to the power amplifier () at a feeding point through a main supply path that is connected via an inductor (L). A second feeding point is used for enhancement by a capacitor that is discharged. A transformer L, L, M) is formed by mutually coupling an additional inductor (L), through which an additional supply path is connected. Enhancement power is provided partially through the transformer L, L, M) and the remaining part thorough the capacitor (C). This way, the total level of possible enhancement is increased, while minimizing distortion of the envelope of the amplified RF signal.

Transformer-capacitor enhancement circuitry for power amplifiers

Apparatus for detecting the envelope of an RF signal that comprises an RF transistor operating essentially at a non-linear operating point at the RF frequency range; a DC power supply for feeding the RF transistor; a dummy load for terminating the output of the RF transistor; and at lease one impedance, through which the DC power supply feeds the RF transistor, for obtaining an indication signal developed across the impedance. The indication signal represents the envelope, from the fluctuating current drawn by the RF transistor from the DC power supply during the time period when the RF signal is applied to the feeding input.

Methods and apparatus for detecting the envelope of RF power signals

A method for regulating the power supplied to an amplifier by providing the power supply input of the amplifier with a current via a coil or a diode connected to a constant voltage power supply, and with additional current diverted from a controlled current source, wherein the magnitude and direction of the additional current is adjusted according to a modulating signal.

Method and apparatus for dynamically regulating the supply voltage of a power amplifier

Method and circuit for stabilizing the output power of a power amplifier, operated with signals having a large peak-to-average ratio and fed by a DC power supply with fluctuating output voltage. An allowable fluctuating range for the voltage output from the DC power supply and a constant voltage level are determined. A controllable voltage enhancement circuitry that can output an enhancement voltage is provided. The input of the voltage enhancement circuitry and a first DC supply path are connected to the output of the DC power supply. The output of the voltage enhancement circuitry is connected to a second DC supply path. While the instantaneous value of the fluctuating output voltage is lower than the constant voltage level, the voltage enhancement circuitry generates an enhancement voltage that causes the sum of the voltages supplied through the first and the second supply paths, to be identical to the constant voltage level.
