First Claim
Patent Images
1. A domestic appliance having a man-machine interface for controlling the operation thereof, the man-machine interface comprising:
- first and second relatively moveable members;
wherein said second member comprises means for generating a signal;
wherein said first member comprises means for sensing the signal generated by said second member and for outputting a signal which varies dependent upon the relative position of said first and second members;
means for controlling the appliance dependent upon the sensed relative position of said first and second members;
wherein the first member is located within a housing of the appliance and the second member is provided external to said housing and being moveable by a user relative to said housing; and
wherein said second member comprises a resonator.

Abstract
A man-machine interface is provided for a domestic appliance in which remotely sensed buttons, slider bars, marker pucks and a knob are used. The sensing coils for remotely sensing the positions of the buttons, slider bars, marker pucks and the knob are formed on a printed circuit board which is located behind a sealed surface such that there is no risk of contaminants accessing the printed circuit board.
