Abstract: A system includes a repeater and a data processor. The repeater is for relaying data between a base station and a handset. The repeater is configured to receive data from a plurality of cells in a network and relay at least a portion of the received data to a handset on a first channel. The data processor is coupled to the repeater. The data processor is configured to extract, from the received data, network information characterizing different channels in a network being utilized by neighbor cells. The data processor is configured to determine, from a set of supported channels that the repeater is capable of utilizing for relaying data and using the extracted network information, a set of monitor channels. The repeater is configured to monitor a channel characteristic of channels contained in the set of monitor channels. Related apparatus, systems, techniques and articles are also described.

Abstract: A repeater system for relaying wireless communications between a base station and one or more devices having: a repeater to relay network information from a base station to one or more devices; a donor antenna configured to receive and/or transmit network information between the repeater and the base station; a power supply external to the repeater; and, a server antenna integrated with the power supply, the server antenna configured to receive and/or transmit network information between the repeater and the one or more devices.

Abstract: A performance testing device for acid fracturing fluid includes: two semiterete rock core holders, the flat face sides of the two semiterete rock core holders being arranged opposite to each other; the two semicircle sides of the two semiterete rock core holders being provided with a rotation member which is opened with a first groove; the two semiterete rock core holders being able to rotate about a first rotation axis formed corporately by the two rotation members; a pressure applying shell having a recessed portion that matches with the curved face side, the recessed portion being able to cooperate with the curved face side, the pressure applying shell being able to apply a pressure to the two rock core holders to bring the two flat face sides thereof together.

Abstract: An antenna system includes a donor antenna sub-system, a server antenna sub-system, and a processor to optimize the gain of the repeater in the system. The gain in the antenna system is increased by optimizing the isolation between the donor and/or server antenna sub-systems according to a cost function.

Abstract: The present invention relates to viscoelastic fracturing fluids comprising one or more zwitterionic surfactants having multiple hydrophobic and hydrophilic groups. The viscoelastic fracturing fluids can be used to stimulate reservoir and increase oil and gas production.
