20090000370 | TREAD DEPTH SENSING DEVICE AND METHOD FOR MEASURING SAME - A tread depth measurement system for measuring a depth of a tread provided to a tire on a vehicle. The system includes an energy source for emitting a wireless signal to be transmitted to the tire; a sensor for detecting a return wireless signal emitted from the tire to be transmitted in response to the wireless signal from the energy source; and a housing over which the tire is to roll while attached to the vehicle, said housing separating the sensor from the tire while the tread depth is being measured. A control unit is operatively coupled to the sensor for determining the depth of the tread as a function of at least the return wireless signal detected by the sensor. | 01-01-2009 |

20090195373 | INITIATOR SYSTEM AND METHOD FOR A TIRE PRESSURE MONITORING SYSTEM - An initiator system and method is provided for a tire pressure monitoring system. The initiator system includes a service station through which the vehicle passes. While situated within the service station, an initiation signal is generated prompting data transmission from wheel unit based tire pressure monitoring device to a receiver. An output device may be employed to visually display information responsive to the transmitted data. | 08-06-2009 |
20100090819 | INTEGRATED READ STATION FOR A WHEEL-MOUNTED VEHICLE - A read station and method for a vehicle includes a support pad for admitting and exiting a vehicle onto an upper pad surface; two or more data-receiving systems, one or both of such systems receiving a data transmission from a vehicle situated on the read station pad surface. The data-receiving systems include an identification-data transmission system and a monitored parameter-data transmission system. One or more of the read station data-receiving systems may be configured to effect data transmission from the vehicle as the vehicle moves across the support pad. The information-data transmission system couples a vehicle wheel unit based RFID tag with an electric field established by one or more system antennae disposed on the support pad. The monitored parameter-data communication system includes one or more wheel-unit mounted monitoring device(s) transmitting data to one or more receivers disposed within the read station and an initiator sub-system that transmits a signal from pad based antenna(s) to initiate a data transmission sequence. | 04-15-2010 |
20100122757 | TIRE AND ELECTRONIC DEVICE ASSEMBLY - A tire and electronic device assembly includes an electronic device in which a transponder tag is coupled to a dipole antenna formed by first and second elongate antenna segments. The transponder tag and at least a portion of the dipole antenna are at least partially embedded within a compound having compatible permittivity and conductivity with operation of the dipole antenna and the electronic device is mounted to the tire apex in a position between the tire apex and the tire sidewall at a predetermined distance above an ending of the tire ply and in an orientation placing a longitudinal axis of the dipole antenna perpendicular to the cords of the tire ply. | 05-20-2010 |
20100123584 | METHOD OF EMBEDDING AN ELECTRONIC DEVICE IN A TIRE - A method for embedding a RFID tag in a tire includes: selecting a compound having compatible permittivity and conductivity with operation of a tag dipole antenna; embedding a tag transponder device and at least a portion of the dipole antenna within the compound; orienting the tag to place a longitudinal axis of the dipole antenna perpendicular to cords of a tire ply in an uncured tire; and placing the tag between a tire apex and a tire sidewall of the uncured tire, at a predetermined distance above an ending of the tire ply. The tag may be positioned axially between a tire chafer ending and a tire apex ending and mounted to the tire apex a distance of at least 10 mm above the ply ending. The method may include substantially encapsulating the transponder device and coupled ends of the dipole antenna in the compound; and extending from the encapsulated dipole coupled ends compound-free dipole end segments. | 05-20-2010 |
20100156641 | RFID ENABLED TIRE CONTROL SYSTEM AND METHOD - A tire control system for a vehicle is provided includes an RFID tag mounted to the tire and having a unique tire serial number stored within tag memory accessible to an external reader; a pass-through portal operatively entered and exited by the vehicle; one or more tire-directed antenna positioned within the portal for operatively receiving one or more one data transmissions of the unique tire serial number from the tire-based RFID tag; and one or more tire-directed RFID reader coupled to the tire-directed antennas for operably reading and storing within a tire-based database the unique tire serial number data. A vehicle-based RFID tag is mounted to the vehicle having a unique vehicle serial number stored within tag memory and transmitted to an external reader as the vehicle moves through the portal. A data processing computer is coupled to receive the portal-read unique tire serial number and vehicle serial number and conducts of the portal-read unique tire serial number data and the unique vehicle serial number data against prestored reference tire serial number data and prestored reference vehicle serial number data, respectively. | 06-24-2010 |
20120291936 | EMBEDDED TRANSPONDER AND TIRE ASSEMBLY AND METHOD OF CONSTRUCTION THEREOF - A tire carcass has one or more radially inner ply components extending around an annular bead member to a ply turnup portion, the ply turnup portion extending radially outward from the bead member to a ply turnup end. A carcass barrier layer component is positioned axially inward from and adjacent to the ply component and an electronic tag device is embedded within the tire carcass between the barrier layer component and the ply component in a lower sidewall region of the tire carcass. The electronic tag is positioned at a radial tag distance from a lower sidewall toe location greater than 10 percent of the tire section height distance from the lower sidewall toe location. A radial tag distance is preferred within 15 percent and less than 35 percent of the tire section height as measured with reference to the lower sidewall toe location. The tag is transmission-operative when embedded within the tire carcass between the barrier layer component and the ply component during green tire construction. | 11-22-2012 |
