    摘要： 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.

    摘要： Methods, algorithms, architectures, circuits, and/or systems for managing POR-less integrated circuits are disclosed. The method of validating code from a wireless device can include: (i) broadcasting a signal from a reader to the wireless device, (ii) reading a code transmitted, re-radiated, and/or backscattered from the wireless device, the code having a predetermined quality, characteristic, and/or property, (iii) comparing the code to a reference quality, characteristic, and/or property, and (iv) validating the code when the predetermined quality, characteristic, and/or property matches the reference quality, characteristic, and/or property. Embodiments of the present invention can advantageously provide a reliable approach for validating integrated circuits that do not incorporate a POR circuit, and which therefore may transmit spurious bits of data upon being energized. In addition, embodiments of the present invention advantageously allow an Aloha-type anti-collision function to be implemented in a reader based on POR-less integrated circuits.

    摘要： Process variation-tolerant diodes and diode-connected thin film transistors (TFTs), printed or patterned structures (e.g., circuitry) containing such diodes and TFTs, methods of making the same, and applications of the same for identification tags and sensors are disclosed. A patterned structure comprising a complementary pair of diodes or diode-connected TFTs in series can stabilize the threshold voltage (Vt) of a diode manufactured using printing or laser writing techniques. The present invention advantageously utilizes the separation between the Vt of an NMOS TFT (Vtn) and the Vt of a PMOS TFT (Vtp) to establish and/or improve stability of a forward voltage drop across a printed or laser-written diode. Further applications of the present invention relate to reference voltage generators, voltage clamp circuits, methods of controlling voltages on related or differential signal transmission lines, and RFID and EAS tags and sensors.

    摘要： The present invention relates to surveillance and/or identification devices having capacitors connected in parallel or in series, and methods of making and using such devices. Devices with capacitors connected in parallel, where one capacitor is fabricated with a relatively thick capacitor dielectric and another is fabricated with a relatively thin capacitor dielectric achieve both a high-precision capacitance and a low breakdown voltage for relatively easy surveillance tag deactivation. Devices with capacitors connected in series result in increased lateral dimensions of a small capacitor. This makes the capacitor easier to fabricate using techniques that may have relatively limited resolution capabilities.
