Abstract: Nowadays many electronic devices, such as LCD projector, computer servers, and air fresher etc. require reliable air cooling system to reduce the risk of electronics damage caused by overheating. The present invention disclosed an apparatus integrated with air flow sensor as an alarm apparatus for air flow clog detection. The major prior approach for air flow circulation failure detection is based on an indirect measurement method of temperature monitoring on surrounding environments, which method is suffering from the slow response and poor identification of real-time situation. The present invention will demonstrate the advantages by directly monitoring air flow over by indirectly monitoring the surrounding temperature as for the purpose of preventing air flow path clog.

Abstract: An all-electronic utility gas meter using with micromachined (a.k.a. MEMS Micro Electro Mechanical Systems) silicon sensor to measure gas metrology data for custody transfer or tariff in city gas metering application is disclosed in the present invention. The meter has two separate metrology units. One of the units is located in the main flow channel with the insertion probing configuration while the other is configured as a bypass unit assembly with the main metrology unit. The bypass metrology unit can perform independent metrology tasks and can be exchanged onsite during service, maintenance or repair without dismantle the meter from the service pipeline. The bypass metrology unit also can be used to compare the measured data from time to time and performance self-diagnosis that shall help the performance and data authentication during the meter field service. Both of the units can be powered by battery or external sources. The units can be connected to network as well as provide internal plural storages for data transmission and safety.

Abstract: With increasing demands on data communication and remote control in current industrial processes or gas measurement applications, development of new technologies would be necessary. The current invention presents a MEMS mass flow meter that are cost compatible with conventional variable area flow meters while providing all digital data process including accumulated flow rate measurements, user programmable flow rate alarm and flow data storage. These in-line meters provide packages in pipe diameter from 4 mm up to 100 mm. It is powered with battery and can be used as a stand-alone hand-held option. The meter is also equipped with the industrial standard RS485 Modbus communication interface for easy network and remote management.
