Abstract: The invention provides an angular position sensor (1) comprising two magnets (32, 33) attached to the inside face of a rotor (31) for generating a magnetic field (50) and a magnetism detection device (43) disposed in the magnetic field (50). The magnets (32, 33) are arranged substantially opposite each other with a pole of opposite polarity of each magnet (32, 33) directed towards the centre of the rotor (31). A uniform magnetic field (50) is generated around the magnetism detection device (43) which provides more accurate sensor measurements over both small and large angles of rotation of the rotor (31). Furthermore, the magnets (32, 33) need only be axially magnetised which simplifies construction of the sensor.

Abstract: A controller that provides tactile feedback to an operator comprises a base having force-sensing elements disposed thereon, the base defining a sensing plane having first and second orthogonal axes therein, and a force-transmitting member orthogonally disposed with respect to the base, the force-transmitting member defining a third axis mutually orthogonal with the first and second axes. The force transmitting member moves at least along the third axis in response to an applied force, both to generate an electrically discernible indication and to provide tactile feedback to an operator.
