A query processing method includes decomposing an SQL into logical plans based on data source feature information, to obtain a logical plan set, where the data source feature information is stored in an internal data source feature library of a query engine, and the internal data source feature library is stored in cache space of the query engine; generating physical plans for the logical plan set based on the data source feature information, to obtain a physical plan set; determining query costs of the physical plan set based on the data source feature information, to obtain a physical plan with a highest priority; and executing the physical plan with the highest priority, to obtain a query result queried by a user. A data source registration method and a query engine is further disclosed.

Embodiments of the present invention disclose a network packet loss processing method and apparatus. The method in the present invention includes: comparing a value of a current congestion window of a network with a buffer threshold when a packet loss event is detected, where the buffer threshold is used to indicate a data bearing capability of the entire network, where the data bearing capability is obtained by adding a data bearing capability of a link in the network and a data bearing capability of a buffer of a node in the network; if the value of the current congestion window is smaller than the buffer threshold, not performing backoff processing on the current congestion window; and if the value of the current congestion window is greater than or equal to the buffer threshold, performing backoff processing on the current congestion window.

Network packet loss processing method and apparatus

A test method includes the steps of providing a test optical disc stored data that is reproduced to display a plurality of images having a plurality of single colors, the plurality of single colors comprising a plurality of first single colors; providing a first timer that begins counting for a first predetermined time when the disc player begins to read the test optical disc; displaying test images according to the video signals generated by the disc player that read the test optical disc. The test method further includes the steps of detecting the color of the test images, determining whether the currently detected color is substantially the same as one of the first single colors after the first timer has timed out; determining that the read performance of the disc player is unsatisfactory if the currently detected color is substantially the same as one of first single colors.

Device and method for testing disc player

An auto focusing camera includes a lens unit () including a barrel () and a lens () received in the barrel, a permanent magnet () being fixedly mounted around the barrel of the lens unit and moving with the lens unit when the lens unit undergoes telescopic movement during operation, and a coil seat () with a coil () wound thereon arranged at a side of the permanent magnet. An interlocking device () is formed on the barrel and the coil seat for guiding the telescopic movement of the lens unit.

Auto-focusing camera

A two-step auto-focusing camera includes a lens unit (); a permanent magnet () being fixedly mounted around the lens unit to move with the lens unit; first and second coil seats () with first and second coils () wound thereon being mounted around the lens unit at two opposite sides of the magnet. When electric currents are supplied to the first and second coils, one of the coil seats generates an attraction force to the lens unit, and the other coil seat generates a repulsion force to the lens unit. A flange () extends outwardly from an outer periphery of each coil seat at an end near the magnet to limit the magnet to move between the flanges of the first and second coil seats during movement of the lens unit.

Two-step auto-focusing camera

An auto-focusing camera includes a lens mount (), a lens unit () received in the lens mount, and a motor for driving the lens unit. The lens mount has a pair of connecting pins () extending therethrough for electrically connecting to a printed circuit board arranged under the lens mount. The motor includes at least one coil seat () with coil () wound thereon, and a permanent magnet () being fixedly mounted around the lens unit to move with the lens unit. The at least one coil seat includes a pair of mounting pins () for guiding two ends of the coils to be connected to the two connecting pins of the lens mount.
