Abstract: A portable computer unlike conventional computers in that it has no computer base. It functions as and resembles a book. It has two monitor screens that share the central processing unit, video card, ram, hard drive, and other computer related equipment as needed. Each of the two monitors may display content independently of the other. It's target users are aimed primarily, but not limited to those whose passions lie in music creation, recording, performance and private instruction, as well as school and church choirs and instrumentalists. An example of how this may be used; the system enables a user to view both monitors with a teaching instructor on the left monitor while reading sheet music on the right monitor. When not in use it Folds together one monitor on top of the other for a compact overall configuration suitable for storage and transport.

Abstract: A sensor assembly for sensing the level and type of fuel in a reservoir is provided. The sensor assembly includes a pair of electrically conductive plates extending longitudinally between opposite ends and positioned in laterally spaced relationship with respect to one another. The pair of plates are encapsulated within a substrate of a less electrically conductive material to isolate the plates from one another and from their external environment. The substrate is of a spring-like material which is expandable and contractible in order to vary the height of the sensor assembly.

Abstract: This invention relates to a sensor element in a fuel system, and in particular, to an electro-static potential differential level sensor element for measuring fuel levels and fuel type in a fuel system. A sensor element includes two electrode plates mounted on a dielectric material and secured to a shield plate. The sensor element is extruded to form a three dimensional sensor element, such as a spiral coil, that has an increased capacitance detection ability to measure fuel type and level.
