    摘要: Low power non-volatile non-charge-based variable supply RFID tag memory devices and methods for reading and writing predetermined ID values for a RFID tag are described. The RFID tag memory device includes a reference/bias generator that receives and provides voltages and currents for write and read operations, a clocked comparator that provides a voltage comparison with a reference voltage, a shift register that receives a non-charge-based memory component value saved in the shift register, a memory cell that includes non-charge-based memory components to store corresponding predetermined ID values, a ring counter that provides ring signals to enable sequential writing and reading of the predetermined ID values to and from the memory cell, a write decision component that receives ring signals to enable the write operation, an output select/isolation component for reading and a read/write component to enable reading or writing the predetermined ID values in response to received ring signals.

    摘要: A tracking and location system having an applicator including a syringe with a needle, a tracking unit having a chip, a wireless transponder, and a power supply configured to power the tracking unit. The syringe includes the needle configured to be inserted into and through skin and eject the tracking unit therethrough. The tracking unit includes the chip and the wireless transponder which are in communication with a software application hosted on a mobile device. A location of an animal with the tracking unit implanted, preferably a pet, is viewable on a display of the mobile device.
