20100259216 | CONTACTLESS BATTERY CHARGING DEVICE AND PROCESS - To recharge the battery of a portable object communicating with a reader establishing communication over a modulated electromagnetic field, a recharging process is proposed. The portable object sends at least one waiting message to the reader. The said waiting message tells the reader a waiting time WTXM before the next message. The portable object uses energy from the electromagnetic field to recharge its battery during the waiting period. | 10-14-2010 |

20110189967 | METHOD AND SYSTEM FOR COMMUNICATING DATA WITH AN INACCESSIBLE ELECTRONIC DEVICE - The invention relates to a method of communicating data with an electronic device, comprising the step of receiving signals conveyed by an electrical lead. The method is distinguished in that it comprises the following steps: fitting an RF radiofrequency interface with electrical contacts in the device, extracting signals from the electrical lead, and injecting signals resulting from the extracted signals, in the form of frames of radiofrequency signals in the RF interface with electrical contacts. The invention also relates to a radiofrequency communication device, a system comprising the device and a machine using the device. | 08-04-2011 |
20120185622 | MATCHING METHOD, SYSTEM AND DEVICE FOR DATA EXCHANGE BETWEEN A COMMUNICATION OBJECT AND A PROCESSING UNIT - A matching device carries out data exchange between a processing unit and a wireless peripheral device and/or a communication object associated with the peripheral device. The matching device includes a communication interface with the processing unit; a wireless communication interface with the wireless peripheral device; information stating means for stating technical capacity information to the processing unit, enabling the latter to select an appropriate driver/communication means; and data-processing means. The data-processing means is capable of carrying out a matching of an exchange protocol and/or formats of data to be exchanged between the processing unit and the communication object. The technical capacities stated by the stating means pertains to the wireless peripheral device and/or to the communication object associated therewith, the technical capacities being considered to pertain to the matching device by the processing unit. The invention also pertains to a system and method for implementing the matching device. | 07-19-2012 |

20140030986 | METHOD, CIRCUIT AND CONTACTLESS COMMUNICATION DEVICE WITH ACTIVATED EMITTING - An activated contactless communication circuit includes a device for receiving and transmitting a data-carrying electromagnetic field; a first circuit resonating with a first antenna for receiving data; and a second circuit resonating with a second antenna for transmitting data, the first and second resonating circuits being separate from each other. The transmission is carried out at a frequency phase-synchronized with the frequency of the electromagnetic field for reception. | 01-30-2014 |
20140045442 | ELECTROMAGNETIC FIELD TRANSMITTING AND RECEIVING ANTENNAE ARRANGEMENT - A method for minimizing an interfering current induced in an antenna receiving an electromagnetic field, where the field is generated by a transmitting antenna located near the receiving antenna. The receiving antenna is arranged relative to the transmitting antenna such that the induced current is at least partially cancelled out in the receiving antenna. The invention also relates to an antenna arrangement and to a device comprising the same. | 02-13-2014 |
20140159870 | CONTACTLESS COMMUNICATION METHOD WITH NEGATIVE MODULATION - The present invention concerns a method of radio-frequency communication between a contactless transponder and a reader, in which at least one sideband of the carrier frequency is used for communicating a response from the transponder by modulation of the amplitude of this carrier frequency. The method is distinguished in that the modulation at least partly applies a modulation level greater than 100%, which causes a negative modulation. The invention also concerns a corresponding communication circuit. | 06-12-2014 |
