Abstract: In one embodiment, a spoilboard gasket tile system for increased work-hold vacuum pressure is provided. In particular, a universal work-hold gasketing solution is defined for vacuum table machining processes that can be used in a variety of sizes and applications, where the surface of a porous spoilboard (e.g., MDF/LDF or a porous plastic) is covered by a non-porous gasketing sheet (e.g., an adhesive foam layer) that is configured with a plurality of spaced apertures (holes) sized and located to create a corresponding plurality of focused vacuum passageways to suction clamp any workpiece placed thereon. In one particular embodiment, the spoilboard with gasketing are prepared as an interchangeable tile unit, allowing for dynamic configuration and reconfiguration of an array of spoilboard gasket tiles to cover a vacuum table, as well as for replacement of specific tiles as needed based on localized wear of the tiles.

Abstract: Embodiments of the present invention produce and define a relationship between local voltage and power measurements at a node of an electrical network and system conditions on a remote branch of the network. These local measurements are used to determine an optimal voltage set point at the node that, if realized by a reactive power resource, would affect the flow of reactive power or line current at one or more particular remote branches of the power system in a manner captured by the derived relationship. The change in reactive power required to obtain this voltage set point is also calculated based on local measurements.
