摘要： This invention improves the precision and reliability with which rolling resistance can be measured. This rolling-resistance testing method includes a rolling-resistance measurement stage and a determination stage. In the rolling-resistance measurement stage, a component force meter is used to measure the tangential axial force that occurs in a tire axle when the tire is rotated under load. In the determination stage, the axial force is measured in a no-load stopped state in which the tire has been separated from a drum, said axial force is compared to a threshold, and if the axial force is greater than said threshold, a determination that an anomaly has occurred in the test is made.

摘要： A conductive terminal structure for a piezoelectric device used as part of a tire mountable apparatus is provided. Unlike known electrical connection structures which include a plurality of conductive terminals that are all exposed through a single insulating layer of the piezoelectric device, such as a top layer of the piezoelectric device, the electrical connection structure can be arranged in a one up, one down configuration. In this configuration, at least one conductive terminal is exposed through a top insulating layer of the piezoelectric device. In addition, at least one conductive terminal of a piezoelectric component is exposed through a bottom insulating layer of the piezoelectric device. The electrical connection structure can be used in combination with a connector assembly design to preserve the integrity of the electrical connection between the electrical and mechanical connection structure and a printed circuit board.

摘要： A vehicle positioning system using RFTD tags. HF RFTD tags are mounted in a vehicle wheel, more particularly a tire and an RFID antenna is provided in proximity to the wheel. A controller causes interrogation of RFID tags as the wheel turns and on the basis of the received identifiers ascertains a distance traveled, for example based on known distance between RFID tags on the wheel.

摘要： A pressure gauge of which the presence or absence of a measurement error can be easily checked is provided. A pressure gauge includes: a piston; a first conversion mechanism converting a linear motion of the piston against an elastic force of a spring into a rotating motion about a first rotation shaft, the linear motion being caused by the pressure transmitted from a target to be measured; an index that is fixed to one end side of the first rotation shaft; a dial; momentum detecting means for detecting momentum indicating an amount of movement of the piston; and a pressure sensor measuring a pressure value of the pressure acting on the internal space of the cylinder. Determining means determines whether a difference between a first measurement value and a second measurement value exceeds a predetermined value, the first measurement value being estimated from the momentum detected by the momentum detecting means, the second measurement value being measured by the pressure sensor. Notifying means notifies a user if the difference between the first measurement value and the second measurement value exceeds the predetermined value.
