Abstract:
A vehicle entry/tire pressure management system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. Some antennas can also be configured to transmit a SMART entry LF search field to wake up a portable transmission/reception unit for keyless entry of the vehicle. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals.
Abstract:
An RFID device for tires utilizes a wireless antenna. The antenna is formed of a pair of spaced apart electrically conductive rubber units. The conductive rubber antenna is encapsulated between a pair of non-conductive sheets. A third non-conductive member encircles the conductive rubber antenna and is itself sealed between the first and second sheets of non-conductive material. A microchip is positioned in the slot defined by the space between the units and conductively attached to each of the units.
Abstract:
An antenna coupled to a wireless communication device is comprised of a conductive component, such as a series of conductive elements, that forms a conductor if placed under a threshold force. The conductor is coupled to the wireless communication device so that the wireless communication device is capable of communicating at an operating frequency defined by the length and construction of the conductor. By communicating using the conductor as an antenna, the wireless communication device may provide an indication of force to an interrogation reader. Furthermore, a conductive support element, such as a tuning ring, may be used for communication as well as coupling the conductive component to the wireless communication device. Multiple conductive components may be coupled to the wireless communication device for communicating at multiple frequencies if placed under multiple threshold forces.
Abstract:
A valve-integrated transponder includes an air valve and a casing that are integrated with each other, and is disposed within a tire. The casing houses a substrate having a detecting element mounted thereon, an inverse F antenna element, and a supporting member. The antenna element has a substantially line symmetrical shape where a pair of radiation conductors extend away from each other. A longitudinal direction of the substrate is substantially perpendicular to an axial direction of the air valve, and a lateral direction of the substrate is inclined relative to a well of a wheel rim. The two radiation conductors of the antenna element disposed on the substrate are inclined at a predetermined angle with respect to the substrate, so as to be disposed substantially in parallel to the well that extends at the inner side of the transponder as viewed in the radial direction of the tire.
Abstract:
A sensor mounting assembly for securing a sensor within a pressurized chamber defined between a wheel and a tire, comprises a patch 2 having a fastening surface 2a by a device in which it is securable, in use, to an inner surface of a tire or wheel. A plate 5 having a threaded aperture 4 is embedded in the patch 2. A sensor housing 1 has a threaded shaft 3 extending from it which complements the thread formed in the plate 5, so that the shaft 3 may be screwed into the aperture 4 in order to secure said housing to the exterior of the patch.
Abstract:
A system for wireless data communication between a vehicle and at least one of its tires (10), the system comprising a fixed antenna mounted on the vehicle and an antenna integral with the tire (10), the latter antenna being located in proximity with the tire's (10) belt. The characteristics of the tire belt are chosen in order to achieve an increased transmission distance.
Abstract:
A tire, the tread comprising rubber compounds and including a wear limit surface. At least one wireless temperature measurement system based on surface acoustic wave or bulk acoustic wave technology is embedded in a region of a rubber compound, said region being radially to the outside of a surface radially to the inside of the wear limit surface and the surface radially to the inside of the wear limit surface being, in the unworn state, at a distance from the outer surface of the tread of at most 95% of the thickness of the tread.
Abstract:
A hidden wireless tire pressure monitor, comprising a tire pressure monitor inside a tire, and an air faucet extending out of the tire. A conductive element is provided between the tire pressure monitor and the air faucet. The inside of conductive element electrically contacts the signal transmitting antenna on the monitor PCB in the tire pressure monitor, while the outside of the element connects and communicates with the root of air faucet. The signal transmitting antenna of the tire pressure monitoring system inside tire thereby extends out of the tire through an air faucet to receive a more accurate monitoring signal. Further, the monitor and the air faucet are at the status of pivot joint for adjustment of the installment angle based on the specification of a wheel rim, thereby ensuring the working stability and the tire security when the tire is removed.
