    Abstract: A communication method transmits a detection signal including a valve ID, which is a fixed data string, and detection information, which is a variable data string, performs error detection on the received detection signal, and uses the detection information when there is no error. The communication method generates third data corresponding to the detection information in accordance with a predetermined rule to increase redundancy of the detection information, generates computed data by performing an exclusive disjunction logic operation with the valve ID and data including the detection information and the third data, transmits the detection signal that includes the computed data, receives the detection signal, restores the detection information and the third data by performing an exclusive disjunction logical operation with the received detection signal and the computed data, and determines whether the detection information conforms to the third data.

The device registration capture associated with this event is compared with other device registration captures associated with other, similar events to create the electronic device directory. The electronic device directory entries are preferable filtered to select the devices most likely to be associated with the actual events in question.

    Abstract: In a system for monitoring the pressure of the tires of a vehicle, it is proposed to compensate the raw data of the parameters of the tires only if the comparison of the successive raw data of at least one reference parameter exhibits a deviation, in absolute value, greater than a determined threshold of variation. In a TPMS monitoring system, each wheel unit includes sensors for measuring the parameters of pressure, temperature and acceleration, and elements of storage and autonomous power supply, in conjunction with a processor. The raw data provided by the sensors are stored, compensated and transmitted as finalized data by a radiofrequency emission circuit to a central unit. It is proposed that the wheel unit also includes, in a processing module, comparison elements, external to the processor, for comparing between successive raw data of one and the same parameter that are provided by the measurement sensors.

The antenna may be mounted on the outer surface of the sidewall or embedded within the body of the sidewall. The antenna is connected to the monitoring device with a connector. The connector may be electrically coupled to the monitoring device or may be connected to the monitoring device with a plug and socket connection. When the antenna is outside the body cord, the connector may extend from the antenna through the bead filler, over the top of the turn up, or under the bead ring.

    Abstract: A device for monitoring the tire of a wheel of a vehicle is configured for detecting and transmitting to a receiver, through a wireless connection, information regarding at least one characteristic quantity of a state of the tire, in particular its inflating pressure. The monitoring device has a body for housing a circuit designed to transmit the information to the receiver. The body includes a first body part, made of a first material, and a second body part made of a second material, the first and second body parts defining between them a housing for the circuit. At least the second material is a synthetic material having an electrical permittivity that is substantially constant at the at least one predetermined frequency. Preferably the first and second body parts are rigid and are fixed together by clinching or local mechanical deformation of the first body part on the second body part.

  • Patent number: 8213973
    Abstract: A method for transmitting data is applied to a receiver and a plurality of transmitters. The steps comprise respectively transmitting a data to the receiver at different first transmission times within a transmission interval by the transmitters. Next, the different first transmission times are respectively added with different accumulated values to become the different second transmission times. The different accumulated values are respectively added with a multiple of the different first transmission times. Finally, the transmitters respectively transmit a next data to the receiver at the different second transmission times within a next transmission interval.

  • Patent number: 8212663
    Abstract: A wheel electronic system and a method for operating a wheel electronic system. The wheel electronic system interacts with a tire secured to a vehicle and produces and emits, based on a captured trigger signal, a message containing information on at least one tire parameter measured with the wheel electronic system. The wheel electronic system is operated in an operational mode in which the system is configured to periodically capture the trigger signals in a first time period. Based on a predetermined first operational ratio of the vehicle, the wheel electronic system automatically switches to a test mode, in which the wheel electronic system is configured to periodically capture the trigger signals in a second time period which is substantially shorter than the first time period.

  • Patent number: 8212664
    Abstract: A data communication device includes: an antenna resonance circuit; a detection circuit; an arithmetic processing device; and a first switch. The antenna resonance circuit receives a signal in the ASK (Amplitude Shift Keying) format. The detection circuit demodulates a digital baseband signal based on the reception signal. The arithmetic processing device detects an appearance time of an edge in the demodulated digital baseband signal based on a preamble part of the reception signal. The first switch short-circuits both end of the antenna resonance circuit at first timing in synchronization with the appearance time of the edge.

  • Patent number: 8198993
    Abstract: Described is a procedure for controlling the transmission operation of a tire pressure monitoring device (1) arranged in a pneumatic tire of a vehicle, whereby data telegrams are transmitted in a normal mode of operation (13) in first time intervals, and there is a changeover from the normal mode of operation (13) to a pressure drop mode, if an inspection of the pressure signals indicates a drop in the pressure of a drop speed exceeding a pre-defined threshold value, and data telegrams are transmitted in the pressure drop mode in second time intervals, which are shorter than the first time intervals, and the tire pressure monitoring devices (1) are put into a travel starting mode (10, 11, 12) at the beginning of the travel by activation a roll sensor. Data telegrams are transmitted in the travel starting mode in shorter third time intervals as compared to the normal mode of operation.

  • Patent number: 8193927
    Abstract: In a tire air pressure detection system, a trigger device is caused to transmit a notification trigger signal to notify wheel position detection in advance of outputting a detection trigger signal for signal magnitude measurement. After confirming reception of the notification trigger signal by a transceiver device, the trigger device is caused to transmit a detection trigger signal for wheel position detection. The detection trigger signal is transmitted after the transceiver device is set in a signal reception wait condition. The transceiver device is thus enabled to receive the detection trigger signal to measure a signal magnitude of the detection trigger signal.

  • Publication number: 20120133498
    Abstract: The changing of the azimuth of directivity in which the azimuth of directivity of the antenna that achieves the maximum gain thereof is switched to the azimuths of tires is performed repeatedly for a plurality of cycles during a transmission duration of information. The output value of the antenna whose azimuth of directivity is controlled is sampled separately for each of the azimuths of directivity subjected to the switching. The sampled values are sorted into groups separately for each azimuth of directivity, and are accumulated separately for each group. The position of the tire shown by the azimuth of directivity of the group whose accumulated value is the largest is determined as being the position of the tire equipped with the transmitter that is transmitting the information.
