A charger incorporated in a vehicle wheel supporting rolling bearing unit detects an output voltage of an electric generator and calculates a rotation speed of a hub. When a rotation speed of the hub is in a low speed state where a sensor and a wireless communication device are operated by electric power supplied 5 by a battery, a frequency of wireless communication performed between the wireless communication device and a calculator disposed on a vehicle body side is changed according to the rotation speed of the hub or a traveling speed of a vehicle.

A comprehensive tire pressure maintenance system for use with motor vehicles that includes a TPMS with an externally mounted battery, tubular battery configured for deployment on a valve stem configured to accommodate deployment of the tubular battery, a self-inflating pressure-optimizing tire arrangement, and a self-inflating run-flat tire arrangement and a wireless tire pressure gauge.

A packaging method for a tire pressure monitoring sensor includes a step of placing, a step of pouring, and a step of hardening. In the step of placing, a sensing transmission module is put into a cavity of a modeling unit, and a positioning portion in the cavity restricts the sensing transmission module from moving transversely and toward an inner bottom of the cavity. In the step of pouring, a rubber compound is poured into the cavity and fills the cavity. The sensing transmission module is coated by the rubber compound to form a case on the outer surface of the sensing transmission module. In the step of hardening, the case is hardened and integrally formed with the sensing transmission module to form a tire pressure monitoring sensor which is removed from the cavity.
