摘要： A method of selecting groups of radio frequency RF transponders (tags) for communication between a base station and the tags. The tags are selected into groups according to a physical attribute of the signal sent by the tags to the base station, or according to the physical response of the tags to a physical attribute of the signal sent from the base station to the tags. Communication with the tags is thereby simplified, and the time taken to communicate with the first tag is markedly reduced.

摘要： An RF tag has an enable/disable circuit connected to a critical part of an electronic object/circuit, e.g. a computer mother board. The critical part of the circuit is any circuit component and/or connection that can enable and/or disable the electric circuit operation. Signals are sent to the tag to change data in the tag memory which causes the enable/disable tag circuit to control the critical part to enable and disable the electric circuit. A system checks the status of the tag, e.g. the electronic circuit was paid for, before enabling the electronic circuit.

摘要： The present invention provides an RF tag having an antenna that can be selectively tuned to achieve optimal performance. The RF tag comprises an RF transponder integrated circuit and an antenna connected to the RF transponder integrated circuit. The antenna includes components such as tuning stubs and loading bars that are physically alterable to selectively vary the performance characteristics of the antenna. The tuning stub and loading bar may each further comprising a variably selectable length having elements that may be removed by punching, cutting, etching, laser trimming or other process. The antenna may further comprise a leadframe or a flexible substrate.

摘要： A method, system, and apparatus for sending data from a base station to an RF tag, whereby the RF tag comprises an "intention to write to memory" field, and the "intention to write to memory" field is written before writing the data and cleared after the data is successfully written. If the data transmission is interrupted and partial data is written to the tag, the "intention to write to memory" field will not have been cleared when the tag is checked at a later time through interrogation by a base station.

摘要： A system and method is disclosed for selecting certain subgroups of radio frequency (RF) tags for querying, communicating, and/or identifying by a base station. The base station sends commands to a group tags within a RF field of the base station. The tags use control logic to determine whether or not they meet certain criteria sent out by the commands. This may cause the tags to change state which either prevents or allows a given tag to participate in an identification process. In this way, a given subgroup(s) of tags meeting certain criteria can be selected for querying, communicating, and/or identifying.

摘要： A method of sending data from a base station to a passive RF tag and writing the data to a tag non-volatile memory which detects a “partial write”, where the tag voltage falls during the write process under the voltage sufficient to reliably write the tag non-volatile memory, is presented. The tag voltage is compared to a stable reference voltage during the time the tag memory is being written, and if the tag voltage falls below an acceptable level, a flag in the tag non-volatile memory is cleared.
