Latest Patents
One of Gallagher's latest patents is titled "Anticollision protocol with fast read request and additional schemes for reading multiple transponders in an RFID system." This invention addresses the arbitration of multiple transponders, such as RFID tags, within an interrogation field. The arbitration process is tailored for specific applications and is controlled by software in the transponder or tag reader. The system calculates different wake-up slots for each tag during transmission cycles based on the tag ID and cycle number. Additionally, the tag reader can send a special command to read data from a tag, allowing it to become decoupled from its environment. The tags can operate in either a tag-talk-first mode or a reader-talk-first mode, and the reader can issue a fast read command that includes a read request and communication control parameters. This innovation also introduces methods to reduce the number of active tags in each cycle, improving tag discrimination in the interrogation field.
