Abstract: A battery-less tire pressure monitoring system is disclosed, which is installed in a tire to monitor the status of the tire, such as the air pressure of the tire. The battery-less TPMS has a tire pressure sensor, and a power generation device, wherein the tire pressure sensor is installed on the fixture in the tire, in order to monitor the status of the tire. Besides, the power generation device of the battery-less TPMS is also installed on the fixture of the tire, and is electrically connected with the tire pressure sensor to provide electrical power for the operation of the tire pressure sensor.

Abstract: The present invention relates to a patch-type tire status monitoring apparatus, which comprises a flexible substrate having an adhering side and a signal processing circuit; a tire status monitoring unit that is affixed to the non-adhering side of the flexible substrate; an antenna; and a wireless transmitting unit that is configured to transmit the signals sent by the tire status monitoring unit. The patch-type tire status monitoring apparatus of the present invention can be easily installed by utilizing the flexibility of the substrate to be firmly affixed to a rim. Since the apparatus does not require any exterior cover, the overall weight can be significantly reduced, which ultimately avoids any potential imbalance and misalignment problems on the wheels.

Abstract: This invention disclosed a corona discharge apparatus composed of a plurality of substrate deposited with matrix of carbon nanotubes. By using ventilation device, the airflow can pass through the corona discharge apparatus, and the electric charge produced due to the corona discharge on the carbon nanotubes. The electric charge impacts oxygen molecular is divided two oxygen atoms. The reaction of oxygen molecular and oxygen atom can produce ozone. Furthermore, by performing corona discharge, at least part of the particle of gas will become charged particle, and the present invention further comprises a particle collector used to collect the charged particle. When the particle in the air followed by airflow pass through the corona discharge apparatus, the electric charge produced due to corona discharge on the carbon nanotubes can attach to the particle to achieve the charging.

Abstract: A micro-electromechanical (MEM) process for fabrication of integrated multi-frequency communication passive components is fused into co-fired ceramics by way of “flip chip” for fabrication of a low-cost, high-performance, and high-reliability hybrid communication passive component applicable in the frequency range of 0.9 GHz˜100 GHz. The basic structure of the passive component is a double-layer substrate comprising a low-loss ceramic or glass bottom-layer substrate and a glass or plastic poly-molecular top-layer substrate and an optional ceramic substrate at the lowest layer. As the materials used and the processing temperature in the MEM process is compatible with the CMOS process, thus this invention is fit for serving as a post process following the CMOS process.
