Abstract: A bolus that communicates with an external transceiver by way of radio waves produced by an electrically small H-antenna is described. The electrically small H-antenna is connected to a conductive cylindrical antenna that houses a battery and chipset that includes a transceiver, identification information and at least one sensor. The H-antenna and the conductive cylindrical antenna are arranged so that electrical currents that produce the radio waves are essentially always aligned to work together. The bolus is essentially a hermetically sealed capsule containing the antennas that is meant to be ingested by a cow or other ruminant animal. The bolus is configured to transmit radio waves in essentially an omnidirectional pattern more efficiently when the boluses inside of a cow stomach than when the boluses outside of the cow.

Abstract: A method for using an RFID tag to retain information of an environment, such as high temperature, that is beyond the operable limits of the RFID tag. The method generally comprises providing an RFID tag that has nonvolatile RFID memory that can communicate with an RFID interrogator system. Exposing the RFID tag to a first environment (such as a high temperature) that renders the RFID tag inoperable. Collecting a first sensor value of the first environment and storing the first sensor value in nonvolatile memory accessible by the RFID interrogation system. Later, exposing the RFID tag and the sensor to a second environment that renders the RFID tag operable (such as room temperature). Wirelessly transmitting the first sensor value to the RFID tag via the RFID interrogator system while the first sensor is in the second environment, and storing the first sensor value in the nonvolatile RFID memory while the RFID tag is in the second environment.

Abstract: An RFID apparatus is disclosed generally comprising an RFID reader antenna attached to a microprocessor, the RFID reader antenna adapted to receive a first digital signal from a first RFID sensor and a second digital signal from a second RFID sensor. The RFID apparatus further possesses a converter that converts the first digital signal to a first analog output, such as electrical current, and the second digital signal to a second analog output. The apparatus can further possess a first electrical wire adapted carry the first analog output to a control system when the first electrical wire is connected to the control system. Also the apparatus can possess a second electrical wire adapted to carry the second analog output to the control system when the second electrical wire is connected to the control system. The control system is external to RFID apparatus and independent of the RFID apparatus.

Abstract: A tamper-evident labelling material includes a base layer of synthetic paper that is printable on its upper surface, and an adhesive layer on the lower surface of the base layer. The base layer includes a layer of biaxially-oriented and voided high density polyethylene (HDPE) that has a density of not more than 0.6 cm?3.
