A method and apparatus for electrically interfacing between two or more distinct environments. The method and apparatus are directed to an electrical feedthru with exterior traces traversing a core. The electrical feedthru may be very small, facilitating its use in MEMS devices. The electrical feedthru may also include an over-mold shaped to create a mechanical seal between the two or more distinct environments without the use of an O-ring. The electrical feedthru is not limited to any particular geometry, it may be adapted to fit between any two environments, and thus the traces are not necessarily parallel to a central axis of the core.

Method of fabricating an electrical feedthru

A method of making a fiber optic accelerometer includes (a) drawing an optical fiber through a resin; (b) winding the resin coated fiber onto a disc mounted on an assembly having a central shaft; and (c) curing the resin-coated fiber. The optical fiber may be drawn through a resin by providing a container filled with a resin having an orifice therethrough and drawing the fiber through the orifice. The resin may be cured such that the fiber is bonded to the disc by curing the resin to the fiber and the disc at the same time.

Electrical feedthru

A winterizing seal for a pool skimmer includes a cover plate dimensioned to overlap the margins of the skimmer opening and having a support portion on its rear surface which extends into the skimmer passageway. A resiliently deformable gasket is provided on the support portion and is configured and dimensioned to bear on the side walls of the skimmer passageway to provide a leak-proof seal between the cover plate and the skimmer passageway. The gasket is pressed against the side walls of the skimmer passageway by a compression plate which is coupled to the cover plate by a nut.

Skimmer seal

A skimmer guard has first and second brackets configured to bear against opposite walls of a skimmer passageway, and a plurality of resiliently deflectable ribs extending between the first and second brackets for blocking objects from passing into the skimmer. The ribs are configured and dimensioned to bias the first and second brackets against the second wall of the skimmer passageway to hold guard in a fixed position.
