    摘要： Systems and methods for implementing anti-collision features while providing a wireless asymmetric network are disclosed herein. In one embodiment, a system includes a hub having a wireless control device that is configured to control communications in the wireless asymmetric network architecture and nodes each having a wireless device with a transmitter and a receiver to enable bi-directional communications with the wireless control device of the hub. The wireless control device of the hub is configured to detect a communication from a first node of the nodes, determine whether at least a portion of the communication is unintelligible to circuitry of the hub or circuitry coupled to the hub, and determine whether a collision of communications transmitting at approximately the same time from the first node and a second node has likely occurred when the at least portion of the communication is unintelligible.

    摘要： Frequency divider circuits and architectures, and methods of implementing and using the same, are disclosed. In one embodiment, the frequency divider circuit includes a dynamic section that receives an input signal and outputs an intermediate signal that has a frequency lower than that of the input signal; and a static section that receives the intermediate signal and outputs a signal having a frequency that is lower than that of the intermediate signal. Stages in the dynamic and/or static section can be implemented using thin film transistors (TFTs). Embodiments of the present invention advantageously provide an approach that takes overcomes problems associated with the leakage and speed characteristics of TFTs.

    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.
