The present disclosure relates to a method, adapted to be implemented in an electronic device adapted to be powered by a power source, the method comprising monitoring a variation of an input voltage and/or an input current received from the power source while the electronic device is powered by the power source; and aborting, according to the monitored variation, a first action performed by a power consuming component of the electronic device. The present disclosure also relates to corresponding device, system, computer readable program product and computer readable storage medium.

Method for controlling a device and corresponding device, electronic assembly, system, computer readable program product and computer readable storage medium

The present disclosure relates to an electronic switch for simulating a mechanical rocker switch having a determined current-interrupting capacity, the electronic switch being configured to supply power to an electronic device using an input voltage, and comprises a tact switch for the generation of a control signal, a bistable circuit whose output state depends on said control signal, a switching circuit adapted to the opening and to the closing of a power supply line supplying power to the device, which device consumes a current less than or equal to said determined interrupting capacity, a memory circuit comprising a reservoir capacitor, the tact switch being configured to control opening and closing of the switching circuit and the memory circuit being adapted to the storage of an 'open' or a 'closed' mechanical position of the electronic switch for a predetermined duration according to the reservoir capacitor.

The invention relates to a method of switching communication channels enabling a card reader to communicate with several card circuits, each circuit having a communication channel. The reader applies a power supply voltage to the card by electrical contacts arranged on a connection button. The reader transmits a control signal for controlling the switching of the communication channel to an electrical contact located in the inserted part of the card but not on the button. Finally, the reader sets up activation signals for at least one circuit to enable said circuit to communicate via the connection button. The invention also relates to a removable device and a receiver for reading said device.

The present invention relates to a method for downloading a binary configuration file in a programmable circuit implemented in a device. The device comprises at least one central processing unit, a plurality of connectors, and a programmable circuit enabling all or a part of the signals received by said connectors to be processed and transmitted to at least one other circuit of the device. The device analyzes the signals present on the connectors in order to define what other devices are connected and whether the connections are operational. Then, a configuration file is selected from among a set of configuration files according to the operational connections and is downloaded from a memory of the device into the programmable circuit. The invention also relates to a device having a component programmed according to the method previously described.

An electronic card is disclosed including circuits of the protected zone include at least one control circuit. The electronic card further includes another zone defining a non-protected environment; the circuits of this zone do not need to comply with the distance constraint. The communication between the circuits of the protected zone and the non-protected environment is carried out by a communication circuit allowing or not allowing the electrical signals to pass. The passage of the electrical signals in the communication circuit is conditioned by an electrical control signal sent by the control circuit. Also disclosed is a method allowing the control circuit to be blocked if the electrical status of the signal controlling the passage of the signals does not correspond to the status imposed by the control circuit.
