Abstract:
A tire-pressure monitoring device includes a detecting unit that detects tire pressure information of a tire for outputting a detection signal, a signal processing unit that includes a modulator block and a mixer block to process the detection signal so as to selectively output one of a first band output having a frequency within a first frequency band, and a second band output having a frequency within a second frequency band, an antenna, and an impedance matching network coupled between the signal processing unit and the antenna. The impedance matching network is configured such that an output impedance of the signal processing unit and an input impedance of the antenna are matched.
Abstract:
A tire pressure sensor includes a sensor device providing a first mounting hole and a second mounting hole in different angles and adapted for detecting the pressure of a tire at a wheel rim, an air valve mountable in a through hole at the wheel rim to guide the air pressure of the tire into the sensor device for sensing, and a fastener for selectively fastening the air valve to the first mounting hole or second mounting hole of the sensor device subject to the type of the wheel rim.
Abstract:
A tire pressure monitoring device with an inclinable valve stem is disclosed. The tire pressure monitoring device includes: a main body having a channel, wherein the channel includes a socket segment near one end thereof; the valve stem being movably fixed to a wheel rim and having a domed end movably received in the socket segment wherein the domed end has a threaded hole axially passing therethrough; and a positioning bolt being positioned in the channel from an opposite end of the channel and coupled with the threaded hole, so that the domed end of the valve stem is movably positioned in the socket segment and when the domed end moves, an angle between the connected valve stem and the main body is changed, thereby allowing the main body to abut against the wheel rim.
Abstract:
A smart tire-pressure sensing system and an automatic matching method thereof are disclosed. The smart tire-pressure sensing system has a tire-pressure sensor compatible to multiple encoding systems. The tire-pressure sensor is configured to select one of the encoding systems according to a code identification signal so as to have signal communication with a host. The automatic matching method includes: a) installing the tire-pressure sensor compatible to multiple encoding systems to a tire to be monitored; b) inflating the tire to make its tire pressure greater than a preset threshold; c) entering the tire-pressure sensor into an installing process; d) sending a code identification signal to the tire-pressure sensor; e) making the tire-pressure sensor receive the code identification signal and select one of the encoding systems according to the code identification signal; and f) establishing the signal communication between the tire-pressure sensor and the host.

Abstract:
A smart tire-pressure sensing system with a protection mechanism and a protection method thereof are disclosed. The smart tire-pressure sensing system has at least one host and at least one tire-pressure sensor preprogrammed with multiple encoding systems. The tire-pressure sensor is configured to select one of the encoding systems during an installation period according to a code identification signal so as to establish a signal communication with the host, and to be locked from switching among the encoding systems after a signal locking period since the establish a signal communication is established, so as to prevent the installed tire-pressure sensor from being interfered with or getting reset unintentionally, thereby securing the signal communication between the tire-pressure sensor and the host.

Abstract:
A photocatalytic fabric products and a manufacturing method thereof uses a plasma polymerization process and a sputtering process under the vacuum environment. The protective layer is deposited on the surface of the fabric product. Then, it uses the sputtering process to excite the photocatalytic material. The atom of the photocatalytic material is excited and forms the photocatalytic thin-film on the surface of the fabric substrate. The thin-film has hydrophilic and anti-bacterial properties thereto can enhance the hydrophilic and anti-bacterial functions in the fabric product. Further, it can widely apply to the medical, upholstery, and other fiber-related field.
