20110043335 | METHOD FOR THE OPERATION OF A TRANSPONDER FOR THE RADIO FREQUENCY IDENTIFICATION (RFID) AND RFID TRANSPONDER - The invention relates to a method for the operation of an RFID transponder, which is characterized by the fact that the RFID transponder is operated either in broadcast mode or in bidirectional response mode or simultaneously in both aforementioned modes. The RFID transporter is equipped with a wireless transmitter as well as with a wireless transmission/reception unit for operation in these two modes, said wireless transmitter and wireless transmission/reception unit being operable independently from one another. | 02-24-2011 |
20110037572 | METHOD FOR THE OPERATION OF A TRANSPONDER FOR RADIO FREQUENCY IDENTIFICATION (RFID) AND RFID TRANSPONDER - The invention relates to a method for the operation of an RFID transponder, which is characterized by the fact that the RFID transponder is operated either in broadcast mode or in bidirectional response mode or simultaneously in both aforementioned modes. The RFID transporter is equipped with a wireless transmitter as well as with a wireless transmission/reception unit for operation in these two modes, said wireless transmitter and wireless transmission/reception unit being operable independently from one another. | 02-17-2011 |
20090253439 | METHOD AND SYSTEM FOR CARRYING OUT A TWO WAY RANGING PROCEDURE - The invention relates to a method for carrying out a Two Way Ranging, preferably a Symmetrical Double-Sided Two Way Ranging, between a blind node whose position is unknown and to be determined and at least one reference or mobile node whose position is known in order to determine the location of the blind node, wherein the blind node and the reference or mobile node comprise wireless transceivers for transmitting and receiving radio signals. The invention is characterized in that the Symmetrical Double-Sided Two Way Ranging is initiated by the blind node. | 10-08-2009 |
20090216497 | WIRELESS DATA TRANSMISSION OF A REFRIGERATED CONTAINER UNIT - A system and method for monitoring data associated with a temperature controlled container with a Reefer Unit. The monitored data retrieved from the Reefer Unit is wirelessly transmitted to an evaluation unit via at least one transponder. The transponder is connected via a wireless interface of an antenna with a reader/transmitter. The wireless interface transmits the monitored data via a bus from the reader/transmitter to a converter which then transmits the converted monitored data via a communication interface to the evaluation unit. Aside from retrieving monitored data remotely, the system can also issue remote forward commands to provide full automation and control of such containers. | 08-27-2009 |
20090199317 | Hard hat involving wireless data transmission - The invention concerns a hard hat having wireless protection to monitor human measuring values, such as, temperature, pulse, moisture and other values which are recorded in the head section of a human and transmitted wirelessly to a stationary or mobile reception unit and which monitor the physical constitution of the hard hat user. | 08-13-2009 |
20090027172 | METHOD AND DEVICE FOR THE POWER-SAVING OPERATION OF RFID DATA CARRIERS - A method and a device for power-saving operation of RFID data carriers, whereby the RFID data carrier has a transmission and reception antenna, by way of which data are sent to or received from a transmission/read unit, by means of a radio signal, within a transmission field, whereby the data carrier is configured for a power-saving sleep mode, and switches over to the reception mode by means of a wake-up signal. With the transmission of the wake-up signal, at the same time, a time datum is transmitted to the data carrier, whereby the time datum shows the time that indicates how much time must still elapse until transmission of a command. The data carrier configured with the sleep mode switches over to a reception mode by means of a wake-up signal, whereby the wake-up signal additionally has a time datum that forms a countdown time, and switches the data carrier into the reception mode briefly, after this time has elapsed, thereby causing the data carrier to receive a command. | 01-29-2009 |
20090027171 | METHOD AND DEVICE FOR THE POWER-SAVING OPERATION OF A PLURALITY OF RFID DATA CARRIERS - A method and a device for power-saving operation of a plurality of RFID data carriers, whereby the RFID data carrier has a transmission and reception antenna, by way of which data are sent to and received from a read/write unit, by means of a radio signal, and the data carrier is configured for reception of an energy-saving signal that puts the data carrier into a so-called sleep mode. The read/write unit sends a so-called conditional sleep command to all the RFID data carriers, and the RFID data carriers receiving these data in the transmission field compare the transmitted condition with a status/data detected in the RFID data carrier, whereby the condition detected in the RFID data carrier depends on a sensor input that is connected with the RFID data carrier. The transmission of the signals between the read/write unit and the data carrier is formed by means of a transmission/reception antenna disposed on the read/write device, and a correspondingly disposed transmission and reception antenna disposed on the data carrier. | 01-29-2009 |
