    Abstract: An identification (ID) tag includes a substrate having an input capable of receiving a high frequency signal. For instance, the high frequency signal can be a radio frequency (RF) signal that is generated as part of a radio frequency (RF) ID system. A first charge pump is coupled to the input and is configured to convert the high frequency signal to a substantially direct current (DC) voltage. A data recovery circuit is coupled to the input and is capable of recovering data from the high frequency signal. A back scatter switch is coupled to the input and is capable of modifying an impedance of the input, responsive to a control signal. A state machine is disposed on the substrate and is responsive to the data recovered by the second charge pump, where the state machine is capable of generating the control signal for the back scatter switch in response to the data. The DC voltage from the first charge pump is capable of providing a voltage supply for at least one of the data recovery circuit, the back scatter switch, and the state machine. The data recovery circuit includes a second charge pump that is capable of operating on the high frequency signal simultaneously with the first charge pump. In other words, the first charge pump can generate the supply voltage for the ID tag from the high frequency signal, while the second charge pump simultaneously retrieves the data from the high frequency signal. The first charge pump also includes a means for limiting the amplitude of the DC voltage by reducing the charge pump efficiency, once a threshold voltage is reached.

    Abstract: Methods, systems and apparatuses for RFID readers forming a reader network are described. In an aspect of the present invention, a plurality of RFID readers are configured to interrogate tags. Furthermore, the readers are configured to communicate with one another. Each of the readers include a ID number which identifies that particular reader within a reader network during communications. Each reader includes a network interface module and an optimization module to receive and process statistical data obtained from other readers in the network. Aspects of the present invention include a ‘primary/secondary’ reader network configuration, as well as a ‘distributed elements’ reader network configuration. A set of operational rules for the environment is indicated, and tag interrogations are optimized according to the rules. Readers may communicate according to a “Listen Before Talk” (LBT) protocol to avoid undesirable interference. Individual readers are capable of dynamically establishing and joining a network, and leaving the network in a self-configured and semi-autonomous or autonomous manner.

    Abstract: Dies that are attached to a die plate can be transferred to a substrate. An actuator can be used to cause a die to be released from the die plate and to come into contact with the substrate. For example, the die may cover a corresponding hole in the die plate. The actuator can move a pin into the hole in the die plate, thereby pushing the die from the die plate. The actuator may be actuated by an electromagnetic stimulus. For instance, a solenoid having windings around a tubular core may provide the electromagnetic stimulus to the actuator. Current may be provided to the windings of the solenoid to generate the electromagnetic stimulus that actuates the actuator. The actuator may be provided in the tubular core of the solenoid.

    Abstract: A method, system, and apparatus for interrogating a radio frequency identification (RFID) tag population are described. Tags are interrogated by a reader. The reader and tags engage in communication according to communications algorithms, where data symbols are exchanged between the reader and tags. Furthermore, a reader implicitly controls the operating state of every tag in the tag population by transmitting a single data symbol. Bit patterns may be collected from the tags by the reader, using a variety of interrogation techniques. In a general interrogation, the reader exchanges symbols with the tag population to interrogate the entire tag population. In a specific interrogation, a reader exchanges symbols with the tag population to target a particular tag identification number. Tags may also be placed in a superposition state by the reader, where they respond whenever a received data symbol matches the next bit of their identification number.
