摘要:
There is described an apparatus for providing rotary displacement information indicative of the torque applied to a torsion bar which is rotatable relative to a housing, in which the electromagnetic coupling between a transmit aerial fixed relative to the housing and a receive aerial fixed relative to the housing varies in dependence upon first and second resonators fixed to the torsion bar at spaced axial positions. The first and second resonators have respective different resonant frequencies to enable the signal coupled between the transmit aerial and the receive aerial via the first resonator to be distinguished from the signal coupled between the transmit aerial and the receive aerial via the second resonator.

There is described an apparatus which monitors the orientation of or the rotational movement of a substantially spherical body. The apparatus comprises a substantially spherical body with at least one resonant circuit fixed thereto. A transmit aerial generates an alternating magnetic field in the region of space including the spherical body which induces an electric signal in the or each resonant circuit, and a receive aerial receives an induced sense signal generated in response to said induced electric signal in the or each resonant circuit. The electromagnetic coupling between the transmit aerial and the receive aerial via the or each resonant circuit varies in accordance with the orientation of the spherical body so that the induced sense signal in the receive aerial varies in accordance with the orientation of the spherical body.

A system for providing predictive discovery services to a user. The system includes a mobile, hand-held device having a display for displaying and storing information and a user interface for allowing input of user interest data comprising event and product preferences, user interest criteria, current hand-held device location, and event calendar information about future occurrences and locations for events and products; a database(s) remote from the hand-held device for storing the user interest data; a processing device in data communication with the database that is structured and arranged to identify a proximity boundary near the user's current and future locations; and a data mining device that is adapted to identify factors of discrete interest for the user based on the user's historical, expressed interests input on at least one remote accessible Web site.
