Abstract
According to the present disclosure, a controller includes a base and a continuous sealing layer connected to the base forming an environmentally sealed compartment between the base and a lower surface of the continuous sealing layer. A circuit board is positioned within the compartment, and a rotary knob encoder is positioned on an upper surface of the continuous sealing layer. Movement of the rotary knob encoder is detectable by the circuit board through the continuous sealing layer.
Claims20
A controller comprising:
- a base;
- a continuous sealing layer connected to the base to form a compartment between the base and a lower surface of the continuous sealing layer;
- a circuit board positioned within the compartment;
- and
- a ring-shaped rotary knob encoder positioned on an upper surface of the continuous sealing layer, movement of the rotary knob encoder being detectable by the circuit board through the continuous sealing layer.

A controller comprising:
- a base;
- a continuous sealing layer connected to a periphery of the base to form a compartment between the base and a lower surface of the continuous sealing layer;
- a circuit board positioned within the compartment;
- and
- a rotary knob encoder positioned on an upper surface of the continuous sealing layer, movement of the rotary knob encoder being detectable through the continuous sealing layer.
2 more elements
A controller comprising:
- a base;
- a continuous sealing layer connected to a periphery of the base to form an environmentally sealed compartment between the base and a lower surface of the continuous sealing layer, the continuous sealing layer comprising a pedestal support formed in an upper surface of the continuous sealing layer, the pedestal support comprising a cylindrical shaped body having semi-cylindrical accommodations formed in an outer surface thereof;
- a plurality of cylindrical pins disposed within the semi-cylindrical accommodations;
- a ring-shaped rotary knob encoder positioned about the outer surface of the pedestal support, the ring-shaped rotary knob encoder including:
- an inner surface engaging the cylindrical pins of the plurality of cylindrical pins, the inner surface comprising a plurality of detents;
- and
- a plurality of magnets disposed within the ring-shaped rotary knob encoder at a lower rim thereof and associated with detents of the plurality of detents;
- and
- a circuit board positioned within the compartment, the circuit board comprising at least two Hall switches positioned under the rotary knob encoder and configured to change states when in proximity to the magnets of the plurality of magnets as the rotary knob encoder rotates to detect rotation of the rotary knob encoder;
- wherein the circuit board is configured to generate a control signal indicative of the direction and distance of rotation of the rotary knob encoder.
