Abstract: A vibraphone pickup has a bobbin having two coils, one for outputting an analog signal and one for outputting a digital signal. A plurality of filters and buffers are used to isolate the signals. A rare earth (or neodymium) magnet is used in the center of the bobbin. In one method of use, a vibraphone pickup is used to pick up each note of the vibraphone. The output of each vibraphone pickup is combined and fed into an amplifier.

Abstract: A method of managing leakage of liquid inside a battery system comprises: containing leaking liquid in a non-liquid sensitive region of the battery system so as to protect internal electrical components of the battery system from coming in contact with the leaking liquid; and in direct response to the leakage, expunging the leaking liquid from the battery system. A drain device includes: a body with a port therethrough, the body configured to be positioned in a wall of a container; means for opening the port in response to a first liquid contacting the drain device on an inside of the container; and means for resisting ingress into the container by a second liquid that contacts the drain device on an outside of the container.

Abstract: A vortex separator includes: a housing having a cylindrical chamber therein; an inlet through a mantle of the cylindrical chamber, the inlet positioned at a proximal end of the housing; a pipe that enters the housing at the proximal end and extends axially through the cylindrical chamber toward a distal end of the housing which is closed; an outlet through the mantle, the outlet positioned at the distal end; and a catch basin at the outlet.
