Abstract: A navigation device and a method thereof. The navigation device is applicable to a vehicle. The navigation includes an input module, a storing module, a routing module and a display module. The input module is used for inputting a start address, a destination address and a dimension data of the vehicle. The storing module is used for storing a plurality of sections, each of the sections have a geometric bending data, respectively. The routing module filters sections or bending roads consisted of multiple sections, which are passable by the vehicle, from each of the sections in accordance with the dimension data and the geometric bending data, and plans a navigation path in accordance with a filter result, the start address and the destination address. The display module displays each of the sections and the navigation path.

Abstract: A system for resuming downloading from interruption points includes an application server (1), a local database (5), and client computers (3). The client computers are provided for users to set download conditions which define a scope of a download. The application server includes a data downloading module (11), a download record determining module (12), and an interruption point obtaining module (13). The download record determining module determines whether any download record exists in the local database, in which data were downloaded according to the same download conditions as a current download. If such download record exists in the local database, the interruption point obtaining module obtains a serial number of the last data item registered in the download record, and the data downloading module downloads data from said last data item only. The local database is for storing all the data used and generated by the system.

Abstract: A patent family analysis system includes a number of client computers (10), an application server (12), and a database server (14). The application server includes a patent family searching device (120), a patent family analysis device (121), and a controlling device (122). Any of the client computers may receive information of a patent whose patent family needs to be analyzed. The database server searches for corresponding patent family data according to the patent information. The analysis device then analyzes the patent family data according to a selected analysis type for the patent family, and generates patent family analysis results. The patent family analysis results are displayed through the client computer. A related patent family analysis method is also provided.

Abstract: A patent family downloading system includes a plurality of client computes (10) for providing interactive user interfaces for setting patent downloading conditions and displaying patent family downloading statues; an application server (12) comprising a patent downloading module (120) for downloading patent information from at least one remote database server according to patent downloading conditions set by users, a downloading condition generating module (121) for generating one or more patent family downloading conditions according to a patent selected as a patent family downloading object that needs to be downloaded, a patent family downloading module (122) for downloading patent information on a patent family from a patent family database server according to the patent family downloading conditions, and a monitoring module (123) for automatically monitoring patent family downloading statues; and a local database server (15) for storing the patent information.
