Abstract: A receiver of a signal communication apparatus; the apparatus including a transmitter adapted to transmit coded signals, the receiver for receiving the signal and a wireless interface interposed between the transmitter and the receiver and having a transmitting antenna and a receiving antenna. The receiver includes a decoder configured to decode the received signal and circuitry coupled to the receiving antenna and capable of triggering the decoder if the value of the received signal is outside a logical hysteresis having a first logic threshold having a value smaller than the value of the direct current component of the received signal and a second logic threshold having a value greater than the value of the direct current component of the received signal.

Abstract: A method is to detect a message compatible with the OTA (Over The Air) standard and affected by a wrong ciphering. The method may include receiving the ciphered OTA message; deciphering the OTA message; and reading a counter field of padding bytes in the deciphered OTA message and reading corresponding padding bytes in the OTA message deciphered. The method may also include detecting at least one bit in at least one of the padding bytes of the OTA message deciphered, with the at least one bit being indicative of the wrong ciphering.

Abstract: A method for testing a memory device. The memory device includes a matrix of memory cells having a plurality of rows and columns; the matrix includes a plurality of rows of operative memory cells each one for storing a variable value and at least one row of auxiliary memory cells each one storing a fixed value. The memory device further includes writing circuitry for writing selected values into the operative memory cells, and reading circuitry for reading the values being stored from the operative or auxiliary memory cells. The method includes reading output values from the row of auxiliary memory cells, determining a malfunctioning of the memory device in response to a missing match of the output values with the fixed values, determining a cause of the malfunctioning according to a pattern of reading errors between the output values and the corresponding fixed values, and providing a signal indicative of the cause of the malfunctioning.

Abstract: A method of sensing an amplitude and a phase of a varying electrical signal representing an impedance of an electrically conductive tissue through which an AC stimulation current is forced may include measuring a first amplitude value of the varying electrical signal corresponding to an arbitrary initial phase offset value and assuming the first amplitude value corresponds to the amplitude and assuming the arbitrary initial phase offset value corresponds to the phase. The method may include measuring a second amplitude value of the varying electrical signal at a phase offset different from the phase. The method may further include comparing the second amplitude value with the amplitude, and updating the amplitude and the phase to correspond to one of a maximum and a minimum amplitude value and to a corresponding phase offset.
