Abstract: System and methods for correlating members with clusters of online course content are disclosed. A server system accessing a plurality of course records associated with a plurality of courses from a database. The server system identifies, for each particular course in the plurality of courses, a list of members of the server system that have accessed content associated with the particular course. The server system applies a clustering algorithm to each course to create a third group of courses. The server system determines member demand for courses included in the third group of courses. In accordance with a determination that the member demand for courses in included in the third group of courses is equal to or greater than a member demand threshold, the server system transmits a request for additional course content to a content provider.

Abstract: The present invention relates to a two-phase stepper motor driven toy comprising a toy body having at least one movable member; a transmission mechanism operatively coupled to said at least movable member; an electric drive means for driving said at least movable member which includes a motor control circuitry for generating electrical signals and a two-phase stepper motor operating in response to the generated electrical signals; and a battery power unit.

Abstract: The invention provides an apparatus and method for aligning a bonding tool. A force sensor having a plurality of force sensing sections is configured to measure a force generated by the bonding tool on the force sensor. Each sensing section is adapted to individually detect an amount of force from a part of the bonding tool acting on that sensing section, so that an alignment of the bonding tool may be determined.

Abstract: A modular door access control system incorporates a plurality of wireless door modules. Access request signals are transmitted to a remote access control unit. The control unit transmits access authorizing control signals to a respective one of the modules. A newly installed module, in a selected mode, enters into communication with the unit. The unit in turn transmits an identifier to the module for use in identifying itself to the unit subsequently in response to a received access request.
