A system (1) for the management of data pertaining to a wheel service comprises: a database (2) including, for each tyre of a plurality of tyres, a tyre identification code; at least one tyre measurement parameter representing a physical quantity linked to the tyre or to the use thereof, and a related time mark, which indicates the time the tyre measurement parameter was captured; a knowledge dataset (3) containing reference data; a processor (4) having access to the database (2) and to the knowledge dataset (3) and programmed to process the at least one tyre measurement parameter and the reference data and to generate derived data.

A method of operation of a compute system includes: capturing an image of a surface of a tire; identifying a tire wear in the image; categorizing the tire wear as a bald region, a crack, a foreign object, low tread, or a combination thereof; generating a wear report includes identifying the tire wear as the bald region, the crack, the foreign object, low tread, or the combination thereof; and transferring the wear report for displaying on a display.

A wear computing system (100, 200, 300) for computing a wear of a wheel (3) of a vehicle (2) comprises a revolution sensor (48) configured to detect a number of revolutions of the wheel (3), an acceleration sensor (49) configured to detect an acceleration of the vehicle (2) in a travel direction thereof, and a control unit (7) configured to compute a travel distance of the vehicle from the acceleration of the vehicle, and compute the wear from the travel distance and the number of revolutions of the wheel (3).

A drive-through vehicle inspection system acquiring information from engraved markings on the tire sidewalls of a moving vehicle. Optical imaging sensors disposed on opposite sides of the vehicle acquire images of the sidewall surfaces for each passing wheel assembly. The acquired images are evaluated by a processing system configured to identify, within the acquired images, visible markings engraved into the tire sidewall surfaces which include at first portion having a first optical reflectivity, and a second portion having a second optical reflectivity which is different from the first optical reflectivity. Each identified marking is decoded to retrieve data stored therein, representative of the tire, wheel assembly, and/or associated vehicle onto which the wheel assembly is installed. The retrieved data is incorporated into an inspection report and/or utilized by the vehicle inspection system to access vehicle-specific information contained within an indexed database.

A component life prediction system configured to predict the remaining life of a consumable component installed on an aircraft. The system includes a processor configured to: receive wear information indicative of a current wear state of the component; receive schedule information indicative of a future flight schedule for the aircraft; and determine the remaining life of the component based on the received wear information and the received schedule information.

A method of manufacturing a test tire and a method of setting a tread removal shape include, moving an outline of a tread surface to set a remaining groove outline, setting a point B at the intersection of a line segment extending radially from a point A, on the tread surface at a position corresponding to 70% to 80% of the tread width, and the remaining groove outline, setting the remaining groove outline farther inward than point B as a first removal reference line, setting a line passing through point B and a point L, where a straight line yielded by a tangent to the tread surface at point A being translated to point B as a second removal reference line, and removing a portion of the tread, with reference to a tread removal shape defined by the first removal reference line and the second removal reference line.

A tire comprising an electronic circuit for measuring tread depth of a tread of the tire, wherein a groove is associated with the tread, the electronic circuit comprising a first conductive portion embedded in the tire and comprising a first conductive wire portion which extends in the tread and terminates open at an outer peripheral portion of the tread, a second conductive portion embedded in the tire and comprising a second conductive wire portion which extends in the tire and terminates open at an outer peripheral portion of the groove, and an electronic connection portion, wherein the first and second conductive portions are electrically connected via the electronic connection portion and extend from the electronic connection portion to the outer peripheral portions of the tread and groove, respectively.

A tire management apparatus includes a remaining tread amount acquisition unit configured to acquire a remaining tread amount of tires, a traveling information acquisition unit configured to acquire traveling information of moving objects to which the tires are attached, a replacement time calculation unit configured to calculate a replacement time of the tires in accordance with the remaining tread amount and the traveling information, and a notification unit configured to notify a particular notification target of information on the number of the tires to be replaced at the replacement time when the number exceeds a threshold.

A method of measuring a tread depth of a tire includes transmitting at least one radio wave from a transmitter through a tread of the tire. The at least one radio wave reflected from a road surface is received with a receiver. The tread depth of the tire is determined based on comparing the at least one radio wave reflected from the road surface with the at least one radio wave from the transmitter.

A wear state detection device includes an element configured to generate voltage based on deformation of a tread portion during tire rotation, a voltage detection unit configured to detect the voltage generated by the element, a speed detection unit configured to detect vehicle speed or tire rotation speed, a storage area configured to store waveform data over time of the voltage detected by the voltage detection unit together with the vehicle speed or the tire rotation speed detected by the speed detection unit, a calculation unit configured to calculate frequency of exceedance of a predetermined threshold value based on the waveform data in a predetermined speed range and a predetermined time period stored in the storage area, and a determination unit configured to determine a progress condition of wear of the tread portion based on the frequency of exceedance of the predetermined threshold value calculated by the calculation unit.
