  • Patent number: 6792288
    Abstract: Analogue interface (24) for an, information exchange circuit by amplitude modulation of a carrier wave, comprising an interface input (102, 104) intended to be connected to the terminals of an antenna (22), a demodulator (150) one output of which is connected to a logical unit (26) in the information exchange circuit, and means (106) of supplying a power supply voltage to the information exchange circuit. According to the invention, the interface also comprises means of rectifying and filtering (116, 118) the carrier wave, connected to one input of the demodulator (150) and a device (120, 122, 132) for regulating the said power supply voltage. Application in particular to the identification and sorting of objects or persons.

  • Patent number: 6493808
    Abstract: The invention relates to a device for testing a reprogramable non-volatile memory having dedicated areas protectable in reading, writing and/or erasing and whose access rights consist of configuration words (MC) saved in a configuration area of the memory, said device comprising message transmission/reception means (10) and a received message logic control unit (11) and access controls to the memory, characterized in that it comprises at least one temporary register ensuring an emulation of these access rights, so as to render access protections reversible or irreversible. The invention also relates to the process performed by said device.
