Patent ID: 7712213

Claim:
A method of making a finished encapsulated unit, comprising: constructing a circuit board assembly from a plurality of circuit boards, the circuit boards being spaced apart from each other and interconnected via at least one wire or electrical contact; inserting the circuit board assembly into an internal volume of a shell such that an end of the at least one wire or electrical contact extends outside the internal volume of the shell, the shell having a first end and a second end opposite the first end, an input orifice adjacent the first end, and an output orifice adjacent to the second end and on a side opposite the input orifice; angling the shell relative to horizontal to position the shell such that the input orifice is at a first point lower than any other part of the internal volume of the shell, and such that the output orifice is at a second point higher than any other part of the internal volume of the shell; and injecting an encapsulating compound into the input orifice to fill the remaining internal volume of the shell with the encapsulating compound, wherein the finished encapsulated unit comprises the circuit board assembly, the shell, and the encapsulating compound, wherein the finished encapsulated unit is adapted to be coupled to at least one outside device and communicate with the at least one outside device via the at least one wire or electrical contact.
