Abstract: A method is provided for monitoring a communication between a transmitting equipment item and a receiving equipment item, the transmitting equipment item transmitting control frames (TC_i) toward the receiving equipment item. The method makes it possible to optimize the frequency of transmission of diagnostic frames (TDx_i), thereby making it possible to avoid saturating the communication link and causing an overconsumption of electrical energy, while guaranteeing a high reliability concerning the state of the communication.

Abstract: A method for monitoring a communication between a transmitting equipment item and a receiving equipment item, said transmitting equipment item transmitting control frames (TC_i) to the receiving equipment item. The method makes it possible to take account of the fact that the control frames (TC_i) are not necessarily transmitted at fixed frequency and to adapt the transmission of the diagnostic frames (TDx_i) to the frequency of transmission of the control frames. Upon a significant variation of this transmission frequency, if no diagnostic frame has been transmitted between the two control frames, the instant of transmission of the next diagnostic frame will take account of this aspect.

Abstract: The invention relates to a method for monitoring a communication between a transmitter entity and a receiver entity. It consists of the transmission of diagnostic frames D dedicated to the monitoring of the communication. The objective of the monitoring is to ascertain the state of the communication before the next data communication frame C so as to be able to ensure that the latter has the maximum chance of taking place. Accordingly, at least one diagnostic frame D must be transmitted before the probable next transmission of a data communication frame C. The instant of transmission Tdiag[0] of the first diagnostic frame D is determined from the minimum period to be complied with between the transmission of two communication frames C. The instants of transmission Tdiag[i] of the diagnostic frames D which follow the first diagnostic frame transmitted at the instant Tdiag[0] are determined on the basis of an increasing function.

Abstract: A proximity detector having a power switch 30 which is switched as a function of the approach of an object. The detector includes a MOS depletion transistor T1 which connects one of the terminals 15 of the detector to a control input of a power switch 30 through a control switch T2. A regulator stage 45 is coupled to T1 in order to keep T1 saturated in the closed condition of the detector and to regulate the gate voltage of T1 when the detector is in a open state.
