Abstract: The present power amplifier linearizing module linearizes operation of a power amplifier and operates in parametrizing mode and operation mode. A processing module executes a feed-forward transfer functions set, which includes at least: a transfer function P and a summing function. The transfer function P derives a change signal ΔVa relative to the control signal component received and the summing function summing the incremental change signal ΔVa to an input signal to generate an adjusted input signal. A transfer function G uses the adjusted input signal to generate an RF signal representative of the amplifying of the adjusted input signal based on the control signal component. The processing module determines a linearizing control signal component based on the generated RF signal representative.

Abstract: A duplexer for a communication device having a transmission unit, a reception unit and a shared antenna is disclosed. The duplexer comprises a first signal path between the transmission unit and the reception unit, the first signal path comprises a filter unit filtering the reception signal, the filtering unit provides a filtered signal to the reception unit. The duplexer further comprises a second signal path between the transmission unit and the reception unit. The second signal path comprises a cancellation unit which receives a sample of the transmission signal and produces a compensation signal. The injection of the compensation signal to the first signal path reduces the leakage signal, thereby producing a substantially leakage-free reception signal.

The second input channel is adjacent in time to the first channel input. The second channel further comprises a second adder which adds the first output with the second channel input in order to produce a second output, adjacent in time with the first output. This configuration can be generalized to n inputs and m outputs.

Abstract: There is described a method of assessing severity of a respiratory distress of a patient. The method generally has, using a three dimensional (3D) camera, generating at least a 3D image encompassing at least a thorax region and an abdomen region of the patient; and using a computer, accessing said 3D image; identifying thorax coordinates indicating coordinates of at least a point of the thorax region of the patient in the 3D image; identifying abdomen coordinates indicating coordinates of at least a point of the abdomen region of the patient in the 3D image; determining a thoraco-abdominal distance based on the thorax coordinates and on the abdomen coordinates; comparing the thoraco-abdominal distance with a threshold; and generating a signal based on said comparison, said signal being indicative of a degree of severity of the respiratory distress of the patient.

Abstract: There is described a system for measuring energy consumption of individual electrical devices amongst a plurality of electrical devices. The system is adapted to determine in real time energy consumption while reducing its own consumption of energy by adjusting a transmission rate to between status sensing devices and a consumption evaluation device. The transmission rate is adjusted as a function of learned energy consumption habits and/or consumption characteristics of individual electrical devices.
