Abstract:
A method, algorithm, architecture, circuits, and/or systems for EAS, HF, UHF, and RFID designs suitable for multi-tag read applications using TTF anti-collision schemes are disclosed. In one embodiment, a tag for wirelessly communicating with a reader can include: (i) a memory portion with an identifier, the memory having at least one printed layer; and (ii) a circuit for providing a bit string followed by a predetermined silent period, where the bit string is related to the identifier. The tag can include pre-programmed memory bits (e.g., bits the value of which is programmed by printing), or alternatively, memory bits formed by conventional photolithography, but having connections made using printing technology to form the identifier, for example. A unique identifier for each tag or device used in a system under a given set of operating conditions can allow a reader to distinguish between them based on a length and/or value of a bit string, for example. Embodiments of the present invention can advantageously provide a reliable and simplified approach for multi-tag read capable EAS, HF, UHF, and RFID systems using TTF anti-collision schemes.

Claim (Index 9):
A method of making a tag for wirelessly communicating with a reader in a multi-tag read capable system using a tags-talk-first (TTF) anti-collision scheme, comprising:\n a) printing at least one layer of a memory portion of the tag, the memory portion storing a plurality of memory bits encoding an identifier for the tag; and b) forming a circuit on the tag configured to (i) transmit a bit string to the reader, said bit string being related to said identifier, (ii) cause said tag to remain silent for a unique silent period following complete transmission of said bit string, said unique silent period being determined by variations in environmental parameters, physical parameters, and/or electrical performance of components within said tag, including in said printed layer(s) of the memory portion, and (iii) retransmit said bit string after said unique silent period elapses, wherein said circuit comprises:\n i) an antenna configured to receive a radio frequency (RF) signal from said reader; \n ii) a power-up circuit coupled to said antenna, said power-up circuit being configured to provide an enable signal when said RF signal is received by the antenna; and \n iii) control and readout logic configured to perform control and readout functions of the tag, comprising a plurality of thin film transistors (TFTs).
