US 12,188,789 B2 · Dual mode rotary transducer

Abstract

A rotary transducer is described. The rotary transducer includes a Hall effect sensor, a rotary dial comprising at least two recessed pockets, a first magnet that is positioned within one of the at least two recessed pockets, and a second magnet that is positioned within another one of the at least two recessed pockets. In an acceleration only mode, the rotary dial is rotatable from a center position in a first direction and is not rotatable from the center position in a second direction. This mode is selected when a mode selection screw is inserted into a mode selection orifice. In a bi-directional acceleration/deceleration mode, the rotary dial is rotatable from the center position in the first direction and is rotatable from the center position in the second direction. This mode is selected when the mode selection screw is not inserted into the mode selection orifice.

Dependent claims

A rotary transducer, comprising:

a housing;
a Hall effect sensor;
a rotary dial comprising at least two recessed pockets;
a spring mechanism that interfaces with both the housing and the rotary dial, wherein the spring mechanism centers the rotary dial at a center position with respect to the housing, wherein the spring mechanism provides increasing spring tension that pulls the rotary dial toward the center position when the rotary dial is deflected in a first direction away from the center position, and wherein the spring mechanism provides increasing spring tension that pulls the rotary dial toward the center position when the rotary dial is deflected in a second direction away from the center position;
a first magnet that is positioned within one of the at least two recessed pockets;
and
a second magnet that is positioned within another one of the at least two recessed pockets.
