摘要: Presented is a system and method for providing electrical isolation in vehicle power systems. The method comprises placing linear optimized isolation transformers in structures of a vehicle at positions that minimize the propagation of energy spikes into internal electronic systems, for example in the wing root of an aircraft where electrical cables from a generator associated with an engine enter the fuselage. The system includes a linear optimized isolation transformer with a core that has primary side winding isolated from a secondary side winding by an isolation dielectric. The isolation dielectric maintains a high value isolation independent of pressure differences due to operation at different altitudes. In embodiments, linear optimized isolation transformers for each phase of a power distribution system couple power from a generator through a structure of a vehicle thereby increasing electrical isolation of electrical components inside the structure from electrical surges originating outside the structure.

摘要: A document stand to support paper (or other flexible sheet material) for use as a copy holder while typing or for use to display graphic matter. Using a form with a bent slot on the device's top surface, it allows the bottom edge of either a single or multiple sheets of paper to fit into it. The slot engages the paper in an arc which allows the paper to use its own inherent strength to support itself in an upright position. The flexible paper conforms to this slightly curved shape of the slot allowing it to remain upright without additional rear, side or top supports. This upright position of the paper is tilted slightly back to both increase stability and ease of viewing of the document.
