    摘要: Various technologies for mitigating distortion in coherent image products generated from SAR data are described herein. Synthetic aperture radar (SAR) datasets generated based upon SAR returns from first and second passes of a SAR platform over a scene are received. The SAR datasets can be co-notched at matching sample indices to improve coherence of SAR images generated from the datasets. Windowed SAR data is generated by applying independent windows to subsets of each of the datasets to reduce sidelobe levels of their image impulse responses. Coherent image products are generated based upon the windowed SAR data, wherein an image quality of the coherent image products is improved as compared to coherent image products generated based upon the SAR datasets.

    摘要: A digital programmable timing device to control the acquisition of data by a computer from high response probes in periodic flows. Synchronized sampling of probe measurements uses a phase-locked-loop and counting circuits so that the moment of A/D conversion always corresponds to a programmable displacement of a stationary probe with respect to moving rotor blades independent of RPM. The rotor speed also is measured digitally in one revolution of the rotor shaft.

    摘要: A patient transport device for transporting a patient secured to a secured area thereof may include a first restraint arm disposed about a first longitudinal side of the secured area and a second restraint arm disposed about a second longitudinal side of the secured area opposite the first longitudinal side of the secured area. A head-cage restraint arm may further be disposed about a third leading end of the secured area between the first and second longitudinal sides of the secured area. The first restraint arm, the second restraint arm and the head-cage restraint arm may be operable to transition between an open configuration and a restrained configuration relative to the secured area.

    摘要: An improved poly(vinyl acetate) which on hydrolysis and reacetylation has an intrinsic viscosity of at least about 5 dL/g and an improved poly(vinyl alcohol) which on acetylation yields poly(vinyl acetate) having an intrinsic viscosity of at least about 5 dL/g. Such poly(vinyl acetate) can be prepared by photo-initiated free radical bulk polymerization of vinyl acetate with controlled low initiator concentration, polymerization temperature and reaction time. Such poly(vinyl alcohol) can be prepared by conventional alcoholysis of the poly(vinyl acetate).

    摘要: A split casing (10) of low, coefficient of expansion material, has internal upstream facing slots (12). A semicircular shroud ring (16), of high coefficient of expansion material, carries the vanes (18), and has a tongue (20) sliding within casing slot (12). Casing stop lugs (14) and shroud stop lugs (22) have mutually abuttable surfaces (70,72) to antirotate the shroud within the casing. The distance between abuttable surfaces of the casing is greater than the distance between abuttable surfaces of the shroud ring at room temperature, but the distance are the same at the long time operating temperature.
