Abstract: Systems, methods, and computer media for efficiently processing user log data are provided. The log data is progressively processed in variable sized windows based on a specified time period. The log data may be anonymized to protect user privacy. A log server processes the windowed log data in phases. The first phase includes fast data like page view log data. Subsequent phases include slow data like session data which may build on the page view data processed in the first phase. The log server identifies metrics based on the log data processed at each phase. Based on the identified metrics, the log server may identify interests across a community of users or for specific users.

Abstract: The present invention discloses a frame boundary detection system and a synchronization system for a data stream received by an Ethernet Forward Error Correction layer. The frame boundary detection system includes a shifter, two descramblers, a syndrome generator and trapper. The error trapper includes a big-little endian mode controller for controlling the big-little endian conversion of the error trapper. If the error trapper operates in the big endian mode, the error trapper implements the function of the syndrome generator, operates at the same time with the syndrome generator, and performs a second FEC check, wherein when the shifter performs the FEC check by intercepting data with a length of one frame plus A bits, two start positions of the frame can be verified, where A is a positive integer less than a length of one frame. The invention can improve the frame boundary detection speed and the frame synchronization speed, and increase only a few hardware overheads.

The processing unit uses the real-time information and information about a waypoint as a basis to generate a safety speed range, and uses a navigation route and the positioning information as a basis to determine whether a distance between the navigation device and the waypoint is smaller than a preset distance range. If yes, the processing unit provides a speed limit message based on the safety speed range. A navigation device control method as well as a program-storing computer-readable storage medium and a computer program product enabling implementation of the control method are also disclosed.
