<p>#CMT# #/CMT# The device has a capacitive sensor detecting operating states of the device. A planar electrode (110) is arranged between a current path input (112) and a current path output (114), where the current path input is provided with an electric input signal for powering the device. The current path output is coupled to a load of the device, and another planar electrode (120) is separated from the former planar electrode by a dielectric medium. A measuring signal terminal (122) is provided with a capacitive measuring signal. #CMT# : #/CMT# An independent claim is also included for a method for controlling an input signal for powering a load of a medical treatment device. #CMT#USE : #/CMT# Medical treatment device e.g. dental-medical, powered instrument such as powered scaling hand-piece. #CMT#ADVANTAGE : #/CMT# The operating state of the device is continuously detected and controlled in a simple and flexible manner, with less loss and compact design. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows schematic view of a medical treatment device. 110, 120 : Planar electrodes 112 : Current path input 114 : Current path output 122 : Measuring signal terminal 145 : Dielectric material.</p> |
