摘要： A control system having a source of control signals and a multi-window electrical signal tracking filter. The signal tracking filter includes an operational amplifier operating in the non-inverting mode as a high impedance load, with a plurality of input stages cascaded at the input to the operational amplifier, each input stage having both a frequency determining filter portion and an amplitude determining threshold detecting portion. Each input stage defines a "window" of operation, such that the portion of a control signal or the like inputted to the filter which falls within the "window" will be filtered or attenuated thereby, while the portion of the control signal which falls outside of the "window" will pass unaffected through the filter. Cascading of the input stages allows one to customize the portions of the signal to be filtered for any particular application.

摘要： A fluid cushion is comprised of a top material layer having a first preformed cell pattern formed therein, and first seal lines pattern between cells, respectively, and a bottom material layer having a second preformed cell pattern formed therein. The second preformed pattern is congruent and complementary to the first preformed cell pattern and has a seal line matching the first seal lines, respectively. A first middle material layer has a third preformed cell pattern formed therein, with second seal lines between cells, respectively, the cells in the third preformed cell pattern being a fraction of the size of cells in the first preformed pattern. A second middle material layer has a fourth preformed cell pattern which is congruent and complementary to the third preformed cell pattern and has seal lines between cells matching and joined to the second seal lines to form small center cells, respectively, there being a cluster of small cells bounded by the larger outer cells. A fluid medium is confined in said cells, respectively, the top material layer and the bottom material layer being joined to the first and second middle material layers, respectively, along the first seal lines. Fluid flow passages are formed between selected ones of the small center cells to permit fluid to flow laterally in a common plane for the small center cells formed between said first and second middle layers.
