Abstract: A tire mountable apparatus and a method of fabricating a tire mountable apparatus is disclosed. The tire mountable apparatus includes a first layer, a second layer and a middle layer disposed between the first layer and the second layer. The tire mountable apparatus further includes an electrical device embedded in the middle layer of the tire mountable apparatus. The middle layer of the tire mountable apparatus completely surrounds the electrical device and is formed from a potting compound, The potting compound does not require exposure to heat, air, moisture, or light to clue and does not require solvent evaporation or outgassing of reaction products to cure. The tire mountable apparatus may be constructed by curing the potting compound between the first layer and the second layer.

Abstract: Disclosed is an apparatus for providing an RFID device for integration into a tire. A printed circuit board (PCB) is provided with a pair of asymmetric arms forming notches in opposed ends of the PCB. Helically wound antenna elements are positioned in the notches such that the ends of the asymmetric arms are positioned adjacent the nearest approach of the individual helically wound antenna elements.

Abstract: Disclosed is an apparatus and methodology for providing an RFID device for integration into a tire. A printed circuit board (PCB) is provided with notches in opposed ends of the PCB that are provided with guide portions as a part of the notches that function as threads to guide an end portion of a matching single pitch helical antenna into appropriately placed vias on the PCB. Threading of the helical antenna is assisted by use of an assembly jig having antenna guiding channels and PCB retaining positioning elements.

Abstract: The subject matter relates to methods for communicating with an RFID tag that is positioned out of the line-of-sight of a communications device. A passive reflector is provided corresponding to an antenna resonant at the operating frequency of the tag. The antemia may be supported by an insulative or conductive wand for manual placement within the line-of-sight of both the tag and a communications device wishing to communicate with the tag. The passive reflector receives signals from either or both the tag and communications device and retransmits the signals. In this manner signals are able to “turn a comer” to improve communications capabilities.

Abstract: A new and useful patch (305) that may be used to mount a relatively rigid structure (300) onto the surface of a tire (315) is provided. Such rigid structure (300) may be, by way of example only, an electronics device, printed circuit board, piezoelectric component, or other devices that are relatively more rigid than the material from which the patch (305) or tire (315) is constructed. The present invention helps reduce and control stress concentrations that occur proximate to such structures as the tire experiences repeated deformation during its use.

Abstract: A method of making a mounting patch for mounting an electronic assembly in the inner liner or a pneumatic tire includes the steps of providing a power source, embedding the power source into a quantity of uncured rubber, and curing the uncured rubber by applying sufficient heat and pressure to the uncured rubber such that the power source is secured in the rubber. The provided power source may correspond to one or more batteries. Additional components that may be incorporated with the mounting assembly may include at least one conductive element, which may also be embedded into the quantity of uncured rubber. An antenna may be configured with undulations to allow longitudinal stretching of the antenna and then also embedded into the quantity of uncured rubber. A preferably non-conductive adhesive layer may be applied to selected portion of the power source, conductive element, and/or the antenna before the step of embedding in the uncured rubber.

Abstract: An improved electronics assembly for integration with a tire structure includes an acoustic wave device such as a SAW sensor connected as a feedback element in an active amplifier and further coupled to an antenna element, thus forming an active transmitter configuration. Such a circuit configuration provides for the ability to actively transmit a combination of information from integrated tire electronics to a remote receiver location. The combination of information corresponds to the physical parameters sensed by the acoustic wave device as well as digital data superimposed on the RF signal emitted by the acoustic wave device by selectively switching the amplifier on and off. Optional integrated power sources configure the electronics assembly for operation as an actively transmitting device.
