Patent number: 11190056Abstract: A method and device for transmitting (20) to an electrical element (4) the power of a radio frequency type signal received by a radio frequency receiver (1), e.g., a radio frequency identification (RFID) chip, the receiver (1) having a receiving antenna (2) and a voltage rectifier (3) of the signal received by the antenna (2), the transmission device (20) including a voltage converter (30) connected to the rectifier (3) of the chip and to the electrical element (4). The device includes a control system (40) configured to momentarily derive the signal from the rectifier (3) in order to define an optimal input voltage of the converter (30) for which the input impedance of the converter corresponds to the output impedance of the rectifier (2), and to redirect the DC signal to the voltage converter (30) by providing the converter with an input voltage setpoint corresponding to the optimal voltage.Type: GrantFiled: March 31, 2020Date of Patent: November 30, 2021Assignee: EM MICROELECTRONIC-MARIN S.A.Inventors: Jerome Saby, Maeve Petit, Thomas Coulot

Patent number: 10964184Abstract: An integrated circuit chip (2), an antenna (3) and a tamper loop (4), and in addition to this, a light emitting diode (LED) (20), configured to be activated, i.e. supplied with current, upon a signal received by the antenna (3). The LED (20) is integrated in the device in such a way that when the LED is activated in the above-described way, the LED lights up so as to become visible by the naked eye, on the condition that the tamper loop (4) is in a predefined state, either open or closed. The LED (20) is coupled between the same terminals (8,9) of the integrated circuit chip (2) as the tamper loop (4).Type: GrantFiled: April 2, 2020Date of Patent: March 30, 2021Assignee: EM MICROELECTRONIC-MARIN SAInventors: Christophe Entringer, Thomas Coulot, Fritz Mbumb-Kumb, Matteo Contaldo
