Abstract
A joystick has a lever and a housing. The lever is pivotable around a pivot axis. The joystick has a support plate carrying at least one sensor. The sensor has at least one coil generating a magnetic field. An eddy current is induced into the coil. At least one metal flag is movable relative to the coil. The motion of the metal flag coincides with the tilting motion of the lever.
Claims18
A control device adapted and configured to be electrically connectable to a power operated device, the control device comprising
- at least one body,
- at least one haptic profile,
- at least a pair of moveable metal flags with a variable geometry, and
- at least one sensor electronics with planar coils,
- wherein the at least one body is pivotable around a central pivot point with a corresponding angular position (ϕ) and a distance (R) from the central pivot point, the at least one body is linked to the at least one haptic profile such that the haptic profile provides a tactile feedback to a user when the body is actuated around the central pivot point, the at least one body is adapted and configured to return to its neutral state in a repeatable manner, the at least one body is linked to the at least two metal flags such that the combined motion of the flags provides a directional control in an x-direction and a y-direction based upon R=√(x2+y2) and ϕ=tan−1(y/x);
- and
- wherein the sensor electronics with the planar coils are oriented parallel to the at least two metal flags, the sensor electronics with the planar coils are adapted and configured to generate eddy currents, the variable geometry of the at least two metal flags coupling with an oscillating magnetic field of the eddy currents.
