InactiveUS6988026B2Low costPrecise positioningVehicle testingRegistering/indicating working of vehiclesCapacitanceRadio frequency energy
Arrangement and method for monitoring a tire mounted to the vehicle in which a thermal radiation detecting device detects the temperature of the tire at different circumferential locations along the circumference of the tire. The detected temperatures of the tire are analyzed to determine, for example, whether a difference in thermal radiation is present between the circumferential locations of the tire, and if so, an action is effected in response to the analysis. The thermal radiation detecting devices are preferably supplied with power wirelessly, e.g., through an inductive system, a capacitive system or a radio frequency energy transfer system.

System for obtaining vehicular information
InactiveUS20050273218A1Low costPrecise positioningVehicle testingVehicle seatsDirectional antennaRadio frequency
System for obtaining information about a vehicle or a component therein includes sensors arranged to generate and transmit a signal upon receipt and detection of a radio frequency (RF) signal and a multi-element, switchable directional antenna array. Each antenna element is directed toward a respective sensor and transmitter RF signals toward that sensor and receive return signals therefrom. A control mechanism controls transmission of the RF signals from the antenna elements, e.g., causes the antenna elements to be alternately switched on in order to sequentially transmit the RF signals and receive the return signals from the sensors or cause the antenna elements to transmit the RF signals simultaneously and space the return signals from the sensors via a delay line in circuitry from each antenna element such that each return signal is spaced in time in a known manner without requiring switching of the antenna elements.

Tire with low hydrocarbon emission rubber combination of tread and sidewall components with compositional limitations
InactiveUS7214731B2Eliminate emissionsEmission reductionSpecial tyresInflatable tyresElastomerHydrophobic silica
The invention relates to a tire of a structural combination of tire tread and sidewall components with compositional limitations containing minimal, if any, of in situ formed alcohol and methyl isobutyl ketone byproducts. The tread component rubber composition contains pre-hydrophobated silica reinforcement. The sidewall component contains low unsaturation EPDM or brominated copolymer of isobutylene and p-methylstyrene and may contain pre-hydrophobated silica reinforcement. The silica reinforcement for said tread and sidewall components is a pre-hydrophobated precipitated silica. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or a combination of an alkoxyorganomercaptosilane and a substituted alkylsilane or with a bis-3(trialkoxysilylalkyl) polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof. The alcohol byproduct therefrom is removed from the composite prior to its introduction into the rubber composition(s). In another aspect of the invention, the connecting sidewall rubber composition, and optionally the tread composition is free of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine antidegradant (referred herein to as 6PPD) in order to prevent in situ formation of methyl isobutyl ketone byproduct from the reaction of 6PPD with atmospheric oxygen and / or ozone.

Pneumatic tire having tread including pairs of sipes
InactiveUS6571844B1Rigid enoughImprove propertiesTyre tread bands/patternsNon-skid devicesEngineeringCommon line
Sipes extending from one end of a block to the central area of the block and sipes extending from the other end of the block to the central area of the block (sipes 24, 28, 32 and 36) are inclined in directions opposite to each other. The sipes extending from one end of the block and the sipes extending from the other end of the block intersect a common line extending along the circumferential direction of the tire. Due to this structure, the number of portions of the sipes, which portions are located in the central area of the block, is made greater than that in the peripheral area of the block. The density of sipes is thus increased in the central area of a block where water tends to form when driving on ice, for improving braking and traction properties on ice.
