Abstract: A container transportation monitoring system is disclosed, which comprises a wireless transmitting module, a wireless receiving module, and a monitoring center. The wireless transmitting module is located on a container, and the wireless receiving module is located on a container crane or a tractor. Besides, the wireless receiving unit of the wireless receiving unit receives the container information transmitted through the wireless transmitting unit of the wireless transmitting module, and the container information is then transmitted to the monitoring center through the monitoring transmitting unit. When the monitoring transmitting unit receives the container information, the container information is compared with the database container information stored in a database, and the comparing result is output to the monitoring device.

Abstract: A radio communication method and system for using pattern variation to identify a pre-detection signal is provided, which uses a transmitting end and a receiving end to execute communication. The transmitting end outputs a radio signal with the pre-detection signal, which includes at least a first transmitting waveform, a second transmitting waveform and a third transmitting waveform. The cycles of the waveforms are changed according to a first predetermined relation. The receiving end is used to receive the radio signal and calculate the cycle of each receiving waveform. If the cycles of the first receiving waveform, the second receiving waveform and the third receiving waveform of the radio signal are changed according to a second predetermined relation corresponding to the first predetermined relation, the receiving waveforms are used as the pre-detection signal.

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.
