The control unit includes a controller, such as a handle, transmitting coil, plurality of receiving coils, and plurality of substrates. The handle may be subjected to spring forces which bias the controller toward a neutral position. The transmitting coil is made of electrically conducting paths on one substrate, and the receiving coils are made of electrically conducting paths on another substrate. One of the substrates is connected to the controller and, together with the controller, is movable in relation to the other substrate, which is located in a substantially fixed position. The controller and interconnected substrate may be moved in a variety of positions such that the controller and attached substrate have at least two degrees of freedom.Field of SearchInduced voltage-type sensorMagnetometers With phase sensitive element Magnetic field detection devices Magnetic test structure elements Control moves in two planes Universally pivoted handle Change of inclination or of rate of motion responsive (e.g., inertia and tilt switches) Rotary motion Tilt responsive All video game accessories WITH CONDITION-RESPONSIVE INDUCTANCE ADJUSTING MEANS (E.G., BY ELECTROMAGNET) ADJUSTABLE BY MAGNETIC FORCE BETWEEN RELATIVELY MOVABLE PARTS OF THE INDUCTOR Adjustable air gap Angularly movable Planar type Electrode arrangement BODILY ACTUATED CODE GENERATOR For handicapped user | |
