Konstantin O Aslanidis, Alain Berthon: Method for repeating interrogations until failing to receive unintelligible responses to identify plurality of transponders by an interrogator. Texas Instruments Incorporated, Rebecca Mapstone Lake, Richard L Donaldson, July 27, 1999: US05929801 (122 worldwide citation)

A novel addressing scheme for an RF-ID system or LAN network is presented in which an interrogator(reader) addresses a set of transponders, each transponder in this set having a common addressing scheme, and the addressed transponders respond only upon the matching of their own address with the rece ...

Josef H Schürmann, Konstantin O Aslanidis, Andreas Hagl: Procedure for reading the data stored in a transponder and a transponder system for the execution of the procedure. Texas Instruments Incorporated, Wade James Brady III, Frederick J Telecky Jr, April 10, 2001: US06215437 (102 worldwide citation)

For reading the data stored in a transponder by means of an interrogation device, the interrogation device at first receives the background noise for the purpose of detecting interference frequencies present in this background noise. On the basis of the interference frequencies acquired, coefficient ...

Transponder signal collision avoidance system incudes a reader and wireless HDX or FDX type transponders (A, B) are disclosed, interrogated by the reader (R) by alternately powering and then reading through cycles corresponding to a number of possible transponders in the interrogation field. The cyc ...

Konstantin O Aslanidis, Andreas Hagl: Bit error correction algorithm. Texas Instruments Deutschland, Rebecca Mapstone Lake, Richard L Donaldson, September 7, 1999: US05948116 (84 worldwide citation)

A corrected digital response signal is generated from a corrupted transponder response signal by receiving the response signal an odd number of times, greater than one, and sampling each received response signal a predetermined number of times. Then, the sample values from each transponder response ...

Herbert Meier, Konstantin O Aslanidis: High performance rfid transponder with fast downlink. Texas Instruments Deutschland, Texas Instruments Incorporated, August 6, 2009: US20090195366-A1

A RFID transponder having a high quality factor antenna (LR), and a resonance capacitor (CR) coupled to the high quality factor antenna (LR) for providing a resonant circuit (LR, CR), wherein the RFID transponder is adapted to vary the quality factor of the resonant circuit (LR, CR) such that the qu ...
