A tyre pressure sensor is mounted at the distal end of a valve stem mounted on a wheel. A protective assembly comprises a body which is releasably attached to the wheel, and a cap which is releasably attached to the body. The valve stem and pressure sensor are enclosed within the body and the cap.

The disclosure relates to the field of automobile detection apparatus technologies, and provides a tire pressure sensor including: a sensor body, a valve assembly connected to the sensor body, a locking member, a resilient member, and a button; wherein a fixture block assembly is disposed at a connecting end of the valve assembly; the locking member is disposed within the sensor body, and the locking member limiting the fixture block assembly when the connecting end is inserted into the sensor body; the button is disposed within the sensor body, and when the button receives an external force, the button transmits an external force to the fixture block assembly, so that the locking member relieves limiting of the fixture block assembly. An entire process of installation and disassembly of the tire pressure sensor becomes simpler and faster.

A tire inflation valve associable with a tire pressure monitoring system (TPMS) sensor includes a stem ending in a head equipped with a head body and an adjustable insert associable with the TPMS sensor by a connection element and hinged to the head body to rotate about a transverse axis and allow position adjustment of the TPMS sensor. The adjustable insert allows modifying inclination of the TPMS sensor according to different use conditions.

A pressure sensing assembly configured to be attached to a bicycle wheel having a tire and a rim mounted to the tire. The pressure sensing assembly includes a housing, a pressure transmitting member, a sensing chamber defined by the housing and the pressure transmitting member, and a sensing element. The pressure transmitting member is coupled the housing and has a central portion offset from the plane in a first direction. The sensing element is offset from the plane in a second direction opposite the first direction. The pressure transmitting member is configured to transmit a pressure in the tire to the sensing element via the sensing chamber.

A Bluetooth tire pressure monitoring system (TPMS) includes a sensing host and a receiving host, and the sensing host includes a battery, a control unit, a Bluetooth transceiver unit, a boost/regulation circuit, a pressure sensing unit, an operational amplifier, a gravity sensing unit, a temperature sensing unit and a Bluetooth antenna. The Bluetooth TPMS utilizes low-power Bluetooth wireless communication technology to transmit and receive signals, so as to meet the requirement in low power consumption.

A system for tire pressure monitoring has a tire valve for disposition on a rim of a vehicle and includes a tire valve stem and a tire valve base, a holding means being disposed on the tire valve base and a tire pressure monitoring unit having a housing in which a pressure sensor for measuring the tire pressure and a transmitter for wireless transmission of tire pressure data are disposed. The tire valve and the housing of the tire pressure monitoring unit can be fastened by means of a fastening element which is implemented in one piece or of the same material with the housing and which interacts with the holding means. The holding means and the fastening element are implemented such that a movement of the tire pressure monitoring unit on the tire valve base is only possible in the direction of a rim well.

A housing (4) for a tyre parameter monitoring system is provided. The housing (4) comprises two arms (10, 12) that are shaped and spaced to provide a clamp-in fitting (18) for engaging with a valve stem (34) of a clamp-in type valve (30) such that the valve stem (34) of the clamp-in type valve (30) is pivotably engaged with the housing (4) and such that the angle between the valve stem (34) of the clamp-in type valve (30) and the housing (4) is variable. The housing (4) also comprises a snap connection fitting (16) for engaging a valve stem (8) of a snap-in type valve (6). The snap connection fitting (16) is positioned between the two arms (10, 12).

A stemming system includes a computing device and a stemming device. The computing device includes data processing hardware and memory hardware in communication with the data processing hardware. The data processing hardware includes a transmitter and a receiver. The stemming device is communicatively-coupled to the computing device. The stemming device includes a base portion and a valve-engaging portion. The valve-engaging portion includes a transducer that obtains a measurement communicated to the receiver of the computing device. The measurement includes at least one physical parameter associated with installing a tire-wheel assembly valve to a wheel throughout a process of disposing the valve within a valve hole of the wheel. The processor analyzes a data signature associated with the measurement for determining if the valve has been adequately or inadequately installed by the stemming device.

A tire monitoring apparatus comprises a sensor housing having a connection part integrated with the sensor housing, the connection part having an elongated opening and a corresponding mounting feature in a wheel rim, wherein a screw extends through the elongated opening and connects with the corresponding mounting feature in the wheel rim, thereby when the screw is not tightened fully, the sensor housing can be rotated with respect to the corresponding mounting feature in the wheel rim, and when the screw is tightened fully, the sensor housing is secured in place and does not rotate with respect to the corresponding mounting feature in the wheel rim.
