Patent number: 9334718Abstract: Automatic detection and accurate time picking of weak events embedded in strong noise such as microseismicity induced by hydraulic fracturing is accomplished by: a noise reduction step to separate out the noise and estimate its spectrum; an events detection and confidence indicator step, in which a new statistical test is applied to detect which time windows contain coherent arrivals across components and sensors in the multicomponent array and to indicate the confidence in this detection; and a time-picking step to accurately estimate the time of onset of the arrivals detected above and measure the time delay across the array using a hybrid beamforming method incorporating the use of higher order statistics. In the context of hydraulic fracturing, this could enhance the coverage and mapping of the fractures while also enabling monitoring from the treatment well itself where there is usually much higher and spatially correlated noise.Type: GrantFiled: January 5, 2010Date of Patent: May 10, 2016Assignee: Schlumberger Technology CorporationInventors: Henri-Pierre Valero, Sandip Bose, Qiuhua Liu, Ramachandra Shenoy, Abderrhamane Ounadjela

Patent number: 9310401Abstract: A power monitoring device for identifying the state of an electric appliance based on user feedbacks and a power monitoring method thereof are provided. The power monitoring device includes a measurement module, a variation detection and search module, and an electric appliance signature database established based on user feedbacks. When the measurement module detects a variation of a power consumption feature, the variation detection and search module searches the electric appliance signature database according to the variation to obtain electric appliances similar to the variation and the states thereof. A user contributes data to the electric appliance signature database by confirming the search result, or selecting the correct electric appliance and the state thereof. When the user confirms the search result, the power monitoring device establishes an association between the electric appliance and its electric appliance signatures and updates the electric appliance signature database.Type: GrantFiled: June 27, 2011Date of Patent: April 12, 2016Assignee: National Chiao Tung UniversityInventors: Shiao-Li Tsao, Yi-Sheng Lai, Ming-Chun Lin, Yung-Chi Chen

Patent number: 9291477Abstract: Disclosed is an energy metering system, apparatus and method that enables an energy meter to reduce power consumed in communication when remotely inspecting the energy meter under an energy pricing system changed depending on time. To this end, the energy meter transmits information on energy consumption at only a changed time of energy price, and operates in a power saving mode except the changed time. If the information on the energy consumption is transmitted at the changed time, the information on the energy consumption in each period having the same energy price is secured, and therefore, a central server has no difficulty in calculating an energy consumption rate. Thus, it is possible to minimize power consumed in communication while transmitting all the information on the energy consumption, required in the central server. Particularly, a battery is used longer in an environment using the battery, thereby reducing maintenance/repair cost.Type: GrantFiled: August 25, 2011Date of Patent: March 22, 2016Assignee: LSIS Co., Ltd.Inventors: Dong Min Son, Jung Hwan Oh, Jae Seong Park
