    摘要： A frequency selective differential amplifier (400) consistent with certain embodiments of the invention has a plurality of N amplifier stages (401, 402, 403 through 404) that collectively drive load (410). The plurality of N amplifier stages (401, 402, 403, . . . , 404) have input nodes and output nodes. A plurality of N−1 output phase shift circuits (421, 422, . . . , 423) connect the output nodes of the plurality of amplifier stages in a manner that causes output signals from the plurality of output nodes to add together for delivery to the load (410), the plurality of output phase shift circuits (421, 422, . . . , 423) have a plurality of phase shifts of &thgr;(f)={&thgr;(f)1,2; &thgr;(f)2,3; . . . ; &thgr;(f)N−2,N−1}. A plurality of N−1 input phase shift circuits (431, 432 through 433) are coupled to the plurality of input nodes and provide input signals thereto. The plurality of input phase shift circuits (431, 432, . . . , 433) have a plurality of phase shifts of &PHgr;(f)={&PHgr;(f)1,2; &PHgr;(f)2,3; . . . ; &PHgr;(f)N−2,N−1}. To achieve the frequency selectivity of the current invention, &thgr;(f) is not equal to &PHgr;(f), so that output signals from the plurality of N amplifier stages (401, 402, 403, . . . , 404) are added with a frequency dependent phase relationship.

    摘要： A system for the formation of a thick robust transparent floor finish layer from a high solids formulation with an applicator device utilizing micro fiber technology. A micro fiber applicator device can be configured to apply a sufficient amount of an aqueous high solids floor finish to obtain a thick robust finish layer in a single application. One system for applying the floor finish can comprise a source of aqueous floor finish and an applicator wand comprising an application nozzle and application surface. Application surface can comprise micro fiber technology in a pad structure comprising a reservoir foam and a micro fiber applicator surface.

    摘要： A laser diode includes a junction surface configured to interface with an integrated optics slider. Cathode and anode electrical junctions are disposed on the junction surface. The cathode and anode electrical junctions are configured for electrical and mechanical coupling to the integrated optics slider. At least one test pad is disposed on the junction surface that is physically separate from and electrically coupled to one of the cathode and anode electrical junctions. The test pad is configured to be contacted by a test probe and is not configured for electrical or mechanical coupling to the integrated optics slider.
