Modular sealed portable digital electronic controller
First Claim
1. A device, comprising:
- a base;
a first cover bonded to the base to form a watertight first enclosure;
a second cover fastened to the base to form a water resistant second enclosure;
a first circuit board disposed within the first enclosure;
a first connector electrically connected to the first circuit board;
a display electrically connected to the first circuit board, the display being disposed within the first enclosure;
a keypad electrically connected to the first circuit board, the keypad being disposed within the first enclosure;
a second circuit board disposed within the second enclosure; and
a second connector electrically connected to the second circuit board, the first and second connectors being disposed to connect when the second cover is properly positioned on the base.

Abstract
An electronic digital controller, such as a load cell indicator, is disclosed in which a number of components, such as a circuit board, display, and keypad are placed within an enclosure, and the enclosure is bonded closed, such as using an adhesive, to render the enclosure watertight. The keypad is a touch sensitive, capacitive keypad with no moving parts, and it is housed behind a rigid panel. An optoelectronic transceiver allows for data exchange with an electronic memory device housed in the adhesively sealed enclosure and allows for data exchange and for updating or modification of software code housed therein. Other components, such as another circuit board, a power supply, and block connectors, are placed in an adjacent enclosure, and the circuit boards in the two enclosures are electrically connected. The power supply is preferably a potted AC power supply but may also include a battery.

19. A method, comprising:
-
(a) placing a first circuit board, a display, and a keypad in a first housing; (b) bonding the first housing closed to form a first enclosure containing the first circuit board, the display, and the keypad so that a user may not gain physical access to the first enclosure without breaking, cutting, or otherwise piercing the first housing; (c) electrically connecting the first circuit board to a second circuit board; and (d) electrically connecting the second circuit board to a measuring transducer. - View Dependent Claims (20)
