Patent ID: 8889986

Claim:
A kit comprising: a first group of components comprising: a first filter housing section extending around a first space with a first central axis and having axially spaced first and second ends; a second filter housing section extending around a second space with a second central axis and having axially spaced first and second ends; a first coupler defining an opening; a first cable end fitting; and a second cable end fitting, the first group of components configured to selectively combine to define a plurality of different filter housings having different axial lengths, the different filter housings including: i) the first filter housing section having the first cable end fitting connected to the first end of the first filter housing section, and the second cable end fitting connected to the second end of the first filter housing section, the first space configured to receive a first circuit board having a first length; and ii) the first end of the first filter housing section and the first end of the second filter housing section connected to the first coupler to define a combined space configured to receive a second circuit board between the second ends of the first and second housing sections, the second circuit board being longer than the first circuit board, the combined space configured to receive the second circuit board, and to enable the second circuit board to extend into and continuously between the first and second spaces through the opening defined by the first coupler, the first cable end fitting being connected to the second end of the first filter housing section, and the second cable end fitting being connected to the second end of the second filter housing section.
