Abstract: An two-piece, corner framing element is described for connecting two longitudinal swimming pool extrusions having longitudinal pool-liner channels that utilizes the conventional upward projecting liner-anchoring land along a bottom front edge of the pool-liner channels for angularly orienting and securing the longitudinal extrusions together in the field framing a pool corner wall during construction of a swimming pool.

Abstract: An inexpensive, efficient and lightweight integrated small decoy system towed behind an aircraft to power an intense IR emitter for drawing in a missile with an IR sensitive guidance system away from vulnerable parts of a defended aircraft is combined with a system for simultaneously cloaking the aircraft with spectral bands of atmospherically scattered UV solar radiation reflected, and radiated from UV radiant sources mounted on the aircraft to defend against advanced MANPADS missiles with guidance systems sensitive to UV shadows cast by an aircraft in a background sky radiance of atmospherically scattered solar UV. Both the reflected and direct cloaking UV emittance may be spatially and/or temporally modulated to confuse an incoming missile. The UV aspect of this invention may also be combined with other C-MANPADS missiles, such as DIRCM, to provide additional defensive capability.

Abstract: An invented computer curve construction system is described that enables construction of conics more intuitively, predictably, and accurately. Also new constructions of particular cubic Bezier curves and their conic analogs are described.

Abstract: An invented fluidic (hydraulic/pneumatic) actuation system is described wherein bidirectional, hydraulic/pneumatically driven elements of multiple components in a common hydraulic/pneumatic circuit inherently provide increases in pressure upon reaching mechanical end points limiting, arresting or stopping further mechanical movement or travel of the driven element of any particular component that switches a sequencing valve system and/or electro-hydraulic/pneumatic pressure switches for directing hydraulic/pneumatic power to other hydraulically/pneumatically driven components in the hydraulic/pneumatic circuit in a timed, sequenced and velocity controlled manner.

Abstract: A real time fingerprint verification system includes a recording device and a verification device each having a fingerprint scanner for generating a flat, dimensionally undistorted, high contrast, fingerprint image, and an intensity sensitive, spatial light modulator (SLM) for receiving and transforming the flat fingerprint image into a planar, coherent light image. In the recording device, the planar coherent light image beam of the fingerprint from the SLM is Fourier transformed, and input into a microscope objective lens system which expands the Fourier transformed beam image sufficiently to allow mechanical blocking of its central portion or order, whereupon it is directed to interact as an object beam with a reference beam from the particular coherent light source to record a holographic matched filter.
