Abstract: A system for processing information requests associated with mobile devices comprises an evaluation module configured to determine at least one performance measure for each of a plurality of information documents using at least data in one or both of a requests database and events database. The at least one performance measure includes at least one of an impression-based performance measure, a click/call-based performance measure, and an off-line site-visit-based performance measure. The system further comprises an information server configured to select a first information document for transmitting to a first mobile device to fulfill a first request.

Abstract: The present disclosure provides method and apparatus for measuring effect of information delivered to mobile devices. In certain embodiments, a method performed by one or more computer systems coupled to a packet-based network comprises receiving a first plurality of request data packets via the packet-based network, receiving panel data packets via the packet-based network, and selecting a set of calibration mobile devices from the first plurality of mobile devices, each of the set of calibration mobile device having transmitted at least one of the panel data packets. The calibration mobile devices are used to derive a calibration factor.

Abstract: An extensible metallic tube structure has a big hollow tube, an engaging head, a small hollow tube, a locating column, an O-shaped ring, a washer, a C-shaped fixing device, and a controlling sleeve. The big hollow tube having an inwardly indented groove at the upper periphery is engaged with the engaging head at one end. The small hollow tube fixed with locating column is led through the other end of the big hollow tube. In sequence, the O-shaped ring, the washer, the C-shaped fixing device and the controlling sleeve are led through the upper end of the small hollow tube. The controlling sleeve is screwed up to the engaging head via threads. An inner protruding flange defining the other side of the inwardly indented groove of the big hollow tube will prevent the small hollow tube from coming off when it being extended to the extreme.
