Abstract: An imprint lithography stamp includes a stamp body having a patterned surface and formed from a fluorinated ethylene propylene copolymer. The imprint lithography stamp further includes a backing plate with a plurality of through-holes with portions of the stamp body extending into the through-holes to adhere the stamp body to the backing plate. The patterned surface of the stamp body has a plurality of protrusions extending from the stamp body, which are used to form high aspect ratio features at high processing temperatures. A mold design for forming the imprint lithography stamp and an injection molding process for forming the imprint lithography stamp are also provided.

Abstract: An improved switch for bilge and sump pumps which allows a manual override switch to be connected in the positive side of the power supply and which uses a reed switch actuated Darlington type circuit both of which are protected from reversed polarity connection by a current limiting resistor which is buffered with the protective resistor.
