| 20090096587 | Transponder Actuatable Switching Device - The present invention relates to a switching device for generating a switch signal, a reading device with the switching device and a method for the communication between a reading device and a transponder (T). The switching device includes an antenna ( | 04-16-2009 |
| 20090199206 | DATA STORAGE MEDIUM AND METHOD FOR CONTACTLESS COMMUNICATION BETWEEN THE DATA STORAGE MEDIUM AND A READER - The present invention relates to a method and an accordingly set tip data carrier for contactless, in particular parallel, communication of a reading device ( | 08-06-2009 |
| 20090236414 | METHOD AND APPARATUS FOR PERSONALIZING PORTABLE DATA STORAGE MEDIA - A method is suggested for the simultaneous personalization of several portable data carriers ( | 09-24-2009 |
| 20100014207 | DEVICE FOR ACTUATING AN ACTUATOR - The invention relates to an apparatus ( | 01-21-2010 |
| 20100308957 | DEVICE FOR CONTROLLING AN ACTUATOR - An apparatus includes an energy store for supplying an actuator, an antenna device for receiving, by contactless communication, energy for charging the energy store and one or more control signals comprising a command for triggering the actuator, and a control unit for controlling the supply of energy to the actuator on the basis of the control signals. After the triggering command has been received, the state of charge of the energy store is determined. When this state is less than a state of charge threshold value that is sufficient for triggering the actuator, a response signal to continue contactless communication is transmitted to the transmitting device via the antenna device. When this state is greater than or equal to the state of charge threshold value, the control unit controls the supply of energy from the energy store to the actuator so that it is possible to trigger the actuator. | 12-09-2010 |
| 20110205015 | METHOD FOR CHALLENGE RESPONSE AUTHENTICATION BETWEEN A READING DEVICE AND A TRANSPONDER USING CONTACTLESS DATA TRANSMISSION - A method for challenge-response authentication between a reading device and a transponder based on a contactless data transmission, according to which challenge data (CH) are transferred within an anti-collision loop from the reading device to the transponder by means of one or several commands (AC) of an anti-collision method, with the command or commands (AC) serving to determine transponder identification data. In the command or commands (AC) respective challenge data (CH) are contained in a data field (D | 08-25-2011 |
