Abstract: A millable bridge plug system includes a mandrel having an upper portion and a lower portion with an interlock, a shearing member attached at the upper portion, a sealing member, ring members, cone assemblies, slip devices, and an interlocking drill member at a lower portion of the mandrel. The interlock of the mandrel and the interlocking drill member are modular so that one bridge plug interchangeably connects to another bridge plug. The interlocks are compatible with interlocking drill members of other bridge plugs and vice versa. The interlocking drill member has rotatable cutting blades to drill through sand and other debris between the interlocking drill member and the next bridge plug to be removed. A milling unit can drive rotation of the interlocking drill member to reach the next bridge plug for removal, until the interlocking drill member engages the adjacent interlock of the next bridge plug to be removed.

Abstract: A traffic information update method includes recognizing, by a terminal, a first traffic sign from a road image; detecting whether traffic information of the terminal includes first alert information corresponding to the first traffic sign; if the traffic information of the terminal does not include the first alert information, generating a traffic sign adding instruction corresponding to the first traffic sign; and sending the traffic sign adding instruction to a server. After finding a new traffic sign, the terminal may report a content indication and a location indication of the traffic sign to the server such that the server can directly update traffic information according to the information reported by the terminal.

Abstract: This invention publishes a fault diagnosis and location system for transformer core looseness, consists of vibration sensors, data collection and computer. It is of power transformer fault intelligent diagnosis technology technical field. Fault diagnosis and location method uses three vibration sensors positioned on the top of transformer tank, to obtain vibration signal, uses signal processing to analyze the signal, and obtains fault characteristics of the transformer core looseness. The characteristics respectively are 50 Hz, 150 Hz and 300 Hz frequency components, in which 300 Hz is main feature. When they reach a certain value at one position, it suggests that transformer core looseness near this position. By the comparison of differences among signals of three positions, fault location can be done. This invention manifests fault characteristics accurately and detects core looseness efficiently.
