  • Patent number: 10049060
    Abstract: A semiconductor device includes a processor for running a real-time operating system (RTOS). The RTOS causes the processor to update internal time during a first mode and to stop updating in a second mode. A first counter periodically transmits an interrupt signal to the processor that is coordinated with a periodic counting sequence. A second counter counts while the semiconductor device is in the second mode. A first circuit reads a first count value from the first counter at a starting time of a transition from the first to the second mode, masks the interrupt signal, and causes the second counter to start counting. A second circuit unmasks the interrupt signal from the first counter after a starting time of a transition from the second to the first mode and reads a second count value from the second counter.

  • Patent number: 8820154
    Abstract: A transmission device of a tire condition monitoring system comprises a sensor which detects, as tire information, the condition of gas filled into a tire cavity region, a transmitter which transmits the detected tire information by radio, and a housing which covers the sensor and the transmitter. A surface of the housing defines an opening that connects an internal space within the housing and the tire cavity region. The opening extends on the surface of the housing while forming the shape of a straight line, a curved line, or a combination of a straight line and a curved line. The maximum value of the opening width orthogonal to the direction in which the opening extends is 0.8 mm or less. Even if a flat tire is fixed using a puncture sealant, tire information such as tire pressure information can be appropriately measured and acquired by this transmission device.

  • Patent number: 8810386
    Abstract: A collision avoidance method for transmitting data from multiple wireless tire condition sensors on a vehicle is executed by each wireless tire condition sensor having a unique ID and multiple different wake-up times. After the sensor is operated to sense data, the method has steps of reading the ID and computing a determination value with the ID and a variable, selecting one of the wake-up times according to the determination result, and after the selected wake-up time expires, transmitting the sensed data. As the selected wake-up times of the sensors differ from one another, data collision at the receiving end arising from data transmission from the sensors can be avoided. Additionally, besides the wake-up time, a time gap between data transmitted twice consecutively from each sensor can be employed to achieve data collision avoidance.

  • Patent number: 8789412
    Abstract: A tire condition monitoring system includes a transmission device, a receiving device, and a monitoring section. The transmitting device includes a sensor which detects, as tire information, a condition of gas in the tire cavity area surrounded with a tire and a rim, a transmitter which wirelessly transmits the tire information, and a housing having a wall surrounding the sensor and the transmitter and separating an inner space from the tire cavity area. The housing wall defines a communicating through hole which enables communication between the cavity area and inner space and a selectively non-communicating through hole having a member which is movable between blocking and unblocking positions to impede and enable communication, respectively, between the cavity area and inner space. The receiving device receives the tire information, and the monitoring section determines whether a tire anomaly exists based on the tire information and provides a result.

  • Patent number: 8742912
    Abstract: A self-powered tire pressure sensor device. The sensor device includes a power circuit, an air pressure measurement sensor, a signal circuit and a wireless transmission circuit. The power circuit converts mechanical acceleration experienced by the device into electrical potential using an electromechanical transducer. Mechanical acceleration due to collisions between the mobile sensor device and the wall of the tire while the tire is in motion cause the transducer to emit a small electrical charge. An electrical potential storage element in the power circuit accumulates and stores the charge as electrical potential. Alternatively the power circuit receives and converts electromagnetic energy into electrical potential. The electrical potential powers an air pressure measurement sensor within the tire. A signal circuit and wireless transmission circuit transmit the measurement to a chassis-mounted receiver, which makes the tire pressure measurement available to systems remote from the tire.

  • Patent number: 8742915
    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.
