A device and method for detecting an absolute multi-turn rotation angle. The device includes a housing, a cover plate and a rotating shaft. The rotating shaft is fixed with a main gear, which is meshed with driven gears including a large driven gear and a small driven gear. The main gear is externally meshed with the large driven gear. The driven gears are connected with a two-stage speed reduction device which enables the rotating shaft to rotate multiple circles to slow down to a circle-number gear and enables the circle-number gear to rotate one circle only. Both driven gears and the circle-number gear are provided with bearings. The bearings have magnets therein, and the two magnets are relatively fixed with the driven gears and the circle-number gear, respectively. The top edges of the bearings fit with a printed circuit board, angle sensing chips which are fixed on the printed circuit.

Device and method for detecting absolute multi-turn rotation angle

The present invention relates to a method or system of data archival using a pattern-based and rule-based data archive manager for a flexible, generic archive solution. The method and system allow for the user to create rules and allow for the system to archive based upon those rules input by the user and to select data to be archived against the facts about the data. The system has a rule based data archive manager having a pattern matcher, a decision scheduler and a rule executor, a fact meta-data storage for storing facts, and a rule library storage for storing user input data about rules.

Pattern-based and rule-based data archive manager

The present invention provides a system and methods for flexible data archival using a model-driven approach. The data archive system and method of the present invention provides the operation of moving data from original data repository into archive data repository. Users can specify archive conditions describing which portions of the data will be moved. The method may have steps such as analyzing application content, defining an archive model, transforming the model by generating an archive specification based upon the modeling result and building an application based upon the archive model and deploying the new model and archive application.
