Abstract: A system and method of automatically tuning a reading device that remotely monitors RFID tags or transponders. The reading device utilizes the phase signal of an antenna signal wherein the harmonic of the antenna signal is filtered through a signal coupling transformer and utilizes the antenna current reading to determine the optimal capacitance setting for the reader by adjusting capacitors and storing the relative phase signal and level of current in a processor. In one embodiment, the method comprises supplying power to the reading device, monitoring the power supply, storing data related to the monitored power supply, emitting a signal from an antenna, filtering the harmonic of such signal, outputting the phase signal to a processor and adjusting capacitors based on the phase signal and monitored current.

Abstract: An animal management system includes a beacon, a radio animal tag configured to monitor the proximity of the animal tag to the beacon, and a reader configured to read information from the animal tag.

Abstract: An RFID system provides a transponder having a power store that can be recharged when located within an electro-magnetic field generated by a transceiver unit. The power store can be a battery and/or a capacitor. In certain embodiments, the transponder can communicate over at least two different frequencies so that the real time performance of the transponder can be improved without losing backwards compatibility. The system provides an ear tag for use on livestock with superior durability and overall performance in the field.

Abstract: The present disclosure relates to an electronic tag, and more particularly to an electronic tag including an insulating cap. When the electronic tag is being made, the insulating cap is arranged adjacent to heat-sensitive electronic components. The insulating cap protects the electronics from the heat generated when injection molding with hot plastic.

Abstract: A radio frequency identification system includes an interrogator for generating and transmitting an interrogation signal to a transponder. One or more transponders of the system receive the interrogation signal and return a data signal which includes identification and/or body characteristic information in one of multiple formats. The interrogator receives the data signal, determines the format of the data signal, and decodes the data signal to obtain the identification and/or body characteristic information. The interrogator operates to decode data signals from transponders not capable of transmitting body characteristic information and transponders which are-capable of transmitting body characteristic information.

Abstract: A passive integrated transponder (PIT) tag comprising an integrated circuit and a unitary core is described. The unitary core comprises a coil-forming portion proximate one end thereof and an integrated circuit support portion proximate an opposite end thereof. The integrated circuit support portion extends beneath and supports the integrated circuit.

Abstract: A remotely testable Passive Integrated Transponder (PIT) tag interrogation system is described. The system comprises a remotely activated test PIT tag fixed within the field of the system antenna. By selectively activating the test PIT tag, and determining successful receipt of the test tag identification signal during such activation, remote confirmation of proper operation of the system is achieved. The system also contains components which permit the remote detection of the antenna field by analyzing signals present in the antenna during operation. Remote detection of the natural frequency to which the antenna is tuned is also achieved by analyzing signals present in the antenna during the collapse of the electromagnetic field in the antenna when the antenna drive signal is removed.

Abstract: An animal tracing system having a parasitic premise information panel for attachment to the stud of an ear tag for use in determining the history and origins of an animal after the animal has been slaughtered, the premise information panel contains a bar code and a numeric code to reveal an animal's history and origin, the panel having sufficient strength to remain attached to the identification panel in day-to-day wear but of sufficient weakness so that a user can remove the premise information panel from the animal ear tag without removing the ear tag from the animal carcass and, along with a blood sample, store the panel therewith until a later date, at which time the premise identification information can be referred to a blood test reveals that the animal has a disease. The tainted carcass can be quickly identified by cross-referencing the premise information panel to the ear tag remaining on the carcass.

Abstract: An interrogator for use with a plurality of identification systems using different frequencies and different methods of demodulation and decoding is provided. Each of the identification systems includes at least one transponder adapted to attached to an article to be identified and each transponder includes an antenna for receiving an interrogation signal from the interrogator and for responding to the received interrogation signal with a responsive signal. The responsive signal includes at least an identification portion. The interrogator includes an antenna assembly for transmitting the interrogation signal from the interrogator to the transponder and receiving the responsive signal from the transponders. A processor is provided for processing the responsive signal received by the antenna assembly and creating an output signal substantially corresponding to the identification portion of the responsive signal. A display is provided for displaying the output signal.

Abstract: An antenna includes a transmitter including a first transmit coil wound in a first direction. A second transmit coil is electrically coupled to the first transmitter and wound in a second direction opposite to the first direction.
