Abstract: Provided is a biometric authentication device that can enhance usability, suppress deterioration of authentication accuracy due to ambient noise, and increase tolerance to wiretapping. A biometric authentication device generates a signal pattern toward a living body by using a signal pattern generating means 11, and transmits the signal pattern to the living body in accordance with the signal pattern by a signal transmitting means 12. Further, the device receives a response signal transmitted through the living body by a signal receiving means 13. The device then calculates transfer feature in accordance with the signal pattern and the response signal by a transfer feature calculating means 14. Further, the device extracts and collates a feature amount in accordance with the transfer features.

Abstract: A device and method for discovering, identification and monitoring of mechanical flaws in metallic structures is disclosed, based on magneto-graphic/magnetic tomography technique to identify stress-related defects. The technique is specifically optimized for extended, not-accessible underground and underwater metallic structures quality control, emergency alarms as well as timeline planning for structural repairs and maintenance work. Examples of the technique implementation include pipes for oil and gas industry, detection of flaws in rolled products in metallurgical industry, welding quality of heavy duty equipment such as ships, reservoirs, etc. It is especially important for loaded constructions, such as pressured pipes, infrastructure maintenance, nuclear power plant monitoring, bridges, corrosion prevention and environment protection.

Abstract: The invention provides a method for configurable ground monitoring of a workbench, and the method comprises the steps as follows. The step of detecting if each of monitored objects of a monitor device is enable should be performed first. A digital value of each of the monitored objects according to detecting result is then calculated and accumulated. The step of detecting if each of the monitored objects reaches a predetermined number of samples is performed, and the step of calculating an average value of each of the monitored objects according to detecting result is followed. The average measured value is compared with a predetermined digital limit-value of each of the monitored objects; furthermore, a corresponding alarm will be sounded when the average measured value exceeds the predetermined digital limit-value. The digital value and a compared result are then sent, and then the step of detecting if the operator ground connection is enabled is performed.

Abstract: A tire pressure monitoring system includes tire sensors mounted in, on or adjacent respective tires of the vehicle, LF antennas mounted on the vehicle, and an ECU. Each tire sensor is configured to transmit an RF signal and to detect an LF field. Each antenna is configured to transmit an LF field to wake up the tire sensors. The ECU is in communication with the antenna, the tire sensors and a radio configured to receive AM broadcast signals. The ECU can communicate with the radio to inhibit speakers in communication with the radio from emitting sound while each LF field to wake up the tire sensors is being transmitted.
