反射型光センサーを用いた多用途コントロールパネル
This paper describes electrical device control panels featuring rotatable knobs, buttons, sliders and a touchscreen, implemented using a single Neonode® Touch Sensor Module (TSM) to detect all of the different panel inputs.
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals. An incremental rotary encoder converts the angular position or motion of a shaft to digital output. In a control knob, a knob shaft is inserted into a control panel and the rotary encoder is placed underneath the panel. Each knob has a dedicated rotary encoder. In optical rotary encoders a photodiode detects light shining through slits in a metal disk surrounding the knob shaft to determine an angle of rotation. Electromechanical systems need to be protected, particularly from moisture, without hindering the system’s operation.
