First Claim
Patent Images
1. An electronic digital governor assembly, comprising:
- a case;
a polycarbonate plate;
a gasket intermediate said case and said polycarbonate plate;
a keypad containing at least one button;
a printed circuit board housed within said case, said printed circuit board having control circuitry configured for controlling at least one parameter of an energy production device; and
a user interface including a digital display for displaying a value of said at least one parameter and said at least one button for selectively adjusting said value;
wherein said polycarbonate plate, said keypad and said printed circuit board define a substantially air-tight and moisture-tight cavity; and
wherein said digital display is contained within said cavity.
