<p>1. Control or measuring unit of the joystick-type, comprising - a control or measuring means, for instance shaped as a handle, subjecting to spring forces biasing said means towards a neutral position, and acting such that the handle has at least two freedom degrees, - a transmitting coil made of electrically conducting paths on a first substrate or conducting sections of said substrate, - a number of receiving coils made by electrically conducting paths on a second substrate or conducting sections of said substrate and positioned at three-dimensionally predetermined locations in relation to the transmitting coil, - one of the substrates is connected to the control or measuring means and is together therewith movable in relation to the other substrate which is located at a fixed position, - the transmitting coil and receiving coils being embodied such that therewith unique combinations of output signals, characteristic for each of the freedom degrees of the control or measuring means, can be generated.</p> |
