A tire surface managing method, comprising: emitting detecting light to a target object on a surface of a tire; receiving reflected detecting light from the target object and from the surface adjacent to the target object; determining whether the target object protrudes according to a distance calculated according to the reflected detecting light from the target object and a distance calculated according to the reflected detecting light from the surface; determining whether the target object forms a hole on the surface according to the distance calculated according to the reflected detecting light from the target object and the distance calculated according to the reflected detecting light from the surface; receiving the reflected detecting light from the surface to calculate a width of the hole on the tire; and activating a protection mechanism for a vehicle comprising the tire if the width is larger than a width threshold.

A vibration monitoring system includes a plurality of encoders and an analyzer. The encoders are configured to generate multiple pulse train signals for multiple wheels. Each encoder is coupled to a respective one of the multiple wheels and generates a single one of the pulse train signals. The analyzer is coupled to the encoders and is configured to generate multiple pulse per revolution signals and multiple angular velocity signals for the wheels in response to the pulse train signals. Each pulse per revolution signal conveys a single pulse per rotation of the respective wheel. The analyzer is further configured to generate an input phasor array representative of the pulse per revolution signals, generate a response phasor array in response to the angular velocity signals for the wheels, and generate a report that identifies at least one vibrating wheel in response to the input phasor array and the response phasor array.

A method for checking tyres, includes: arranging a tyre in a station for checking tyres; moving a sensor within the tyre; performing first checks on an inner surface of the tyre with the at least one sensor; engaging a radially outer portion of the tyre with grip elements of an overturning device; extracting the sensor from the tyre and spacing the sensor from the tyre; overturning the tyre by 180° by rotation of the grip elements; moving again the sensor within the tyre; performing second checks on the inner surface of the tyre with the sensor; extracting again the sensor from the tyre and spacing the sensor from the tyre; and transporting the tyre outside the station for checking tyres.

A method of detecting degradation of a real tire of a wheel includes the steps of: acquiring at least one first three-dimensional object representative of the shape of the real tire by using an electronic appliance including at least one three-dimensional sensor, the first three-dimensional object being made up of a set of capture points; determining the position of the center point of the real tire from the set of capture points; registering the first three-dimensional object to obtain a second three-dimensional object; transforming the second three-dimensional object in order to obtain one or more two-dimensional objects; and analyzing the two-dimensional object(s) in order to detect degradation of the real tire.

An inflatable device repair kit may include an openable repair packet having a patch surface, a sandpaper surface and a packet interior between the patch surface and the sandpaper surface. At least one tube repair patch may be detachably adhered to the patch surface of the repair packet. An abrasive sanding texture may be provided on the sandpaper surface of the repair packet. A patch cement may be provided in the packet interior of the repair packet. The abrasive sanding texture on the repair packet may be used to smoothen an exterior surface on an inflatable device wall of an inflatable device at a break in the inflatable device wall. The repair packet may be opened and the patch cement in the packet interior applied to the tube repair patch and the tube repair patch applied to the inflatable device wall over the break to seal the break.

An apparatus for detecting a puncture comprises a housing comprising a plurality of compartments. Each compartment comprises an opening for receiving a flow of air into the compartment. Each compartment also comprises a detection element mounted on an axle, the axle having a first end and a second end and being secured at said first end and said second end within the compartment. The detection element is rotatable about the axle and when a flow of air passes through the opening into the compartment, the detection element rotates around the axle in response to the flow of air.

An anti-jet joint structure of a connection hose of a vehicle air compressor contains: an accommodation box, an adhesive supply can, and a connection hose. The accommodation box accommodates the vehicle air compressor started by a power to produce air. The adhesive supply can accommodates chemical adhesive for repairing a tire, and the adhesive supply can includes an open segment and a supply hose. The connection hose includes a first joint and a second joint opposite to the first joint. The first joint is engaged with the supply hose, and the second joint is screwed with a gas nozzle of the tire. The second joint is the anti-jet joint structure and has a first connection assembly and a second assembly. The first connection assembly is connected with or is removed from the second connection assembly having different interior structures and volumes so as to mate with various tires.
