Abstract: This invention provides a method and process for the facile extraction of selected gases by means of a permeable membrane module, also known as a permeator, with effective and beneficial control of temperature the apparatus allowing temperature gradients or isothermal operation.The isolation and removal of subject gases, particularly those arising from combustion, i.e., combustion gases, is usually accomplished by means of absorber and stripper towers containing various packings to facilitate gas-liquid interaction. The inlet temperature has to be controlled but the temperature varies along the length of the tower height. In contrast, a membrane-based separation device, whether it is a permeator design or a traditional two body absorber and stripper, operates better, particularly if driven by a catalyst, under a controlled temperature regimen. This is because, unlike a traditional absorber stripper where liquids may evaporate or condense with little impact on the system operation, evaporation of one phase will cool the other phase resulting in condensation that will slow the diffusion of the combustion gasses of interest.Attempts to provide internal temperature homogeneity by use of an external heat sink have been found wanting due to insufficient transfer of heat between the internal and external sites of the permeator as well as logistic and corrosive concerns with scale-up modules.The use of an internal construct to provide temperature control within the permeator is the subject of this invention. More specifically it is the use of internal transport constructs to precisely control the internal temperature of the permeator without the attendant loss of selectivity caused by employing a rapid flooding with temperature control liquids or gases.

Abstract: A method of passivating the surface of a substrate to protect the surface against corrosion, the surface effects on a vacuum environment, or both. The substrate surface is placed in a treatment environment and is first dehydrated and then the environment is evacuated. A silicon hydride gas is introduced into the treatment environment, which may be heated prior to the introduction of the gas. The substrate and silicon hydride gas contained therein are heated, if the treatment environment was not already heated prior to the introduction of the gas and pressurized to decompose the gas. A layer of silicon is deposited on the substrate surface. The duration of the silicon depositing step is controlled to prevent the formation of silicon dust in the treatment environment. The substrate is then cooled and held at a cooled temperature to optimize surface conditions for subsequent depositions, and the treatment environment is purged with an inert gas to remove the silicon hydride gas. The substrate is cycled through the silicon depositing step until the surface of the substrate is covered with a layer of silicon. The treatment environment is then evacuated and the substrate cooled to room temperature.

Abstract: An optical cross connect, especially a wavelength cross connect, using free-space optics, a diffraction grating, and a micro electromechanical systems (MEMS) array of movable mirrors. A concentrator receives light from widely separated optical fibers and brings the beams together into a more closely spaced linear array. Free-space optics process all the beams. Front-end optics collimate the beams from the fibers and flatten their fields. The diffraction grating spectrally separates each beam into sub-beams. A long-focus lens focuses the sub-beams onto the 2-dimensional MEMS array. A fold mirror reflectively couples two such mirrors, whereby the switched signals propagate back through the same optics and are spectrally recombined onto the fibers. Other embodiments include white-color cross connects, multiple MEMS arrays, and parallel optics. Power dividers or wavelength interleavers can divide signals from the fibers, and multiple cross connects switch different wavelength groups.

Abstract: An improved low profile transformer is disclosed. The transformer has desirable characteristics for switch mode power supplies such as minimum high frequency resistance, improved coupling of primary and secondary windings, and reduced eddy current losses. The transformer has a primary winding comprised of an insulated conducting foil that is folded into a staircase-shaped winding. One or more secondary winding segments comprised of U-shaped conducting sheets are interleaved with the primary winding to form a minimally separated primary and secondary winding. The windings are substantially surrounded by an E-shaped magnetic core to facilitate the magnetic coupling of the windings.

Abstract: A three-dimensional texture is mapped onto a graphically-displayed surface by interpolating locations for elements of the texture using an associated distance relationship which locates the element with respect to the surface and a reference location spaced a distance apart from the surface. A first array of points representing the surface are stored, each of the points having an element of the three-dimensional texture and a distance to the element associated therewith. Upon a command to move the displayed surface, a new location for each point of the first array is computed, to obtain a second array representing the moved surface. A location for each element of the three-dimensional texture associated with each point of the first array is interpolated from the corresponding point in the second array and a reference location spaced apart from the moved surface.

Abstract: A three-dimensional space may be rendered in a computer graphics system by representing the three-dimensional space as a plurality of convex polyhedra and representing the containment relationships among the plurality of convex polyhedra. Connection relationships among the convex polyhedra, including the location of holes in the connected surfaces, are also preferably represented. Containment and connection relationships are preferably represented using a containment logical tree and a connection logical graph. Three-dimensional graphics representations can thereby be rendered in a real time using a low cost, graphics processor. Efficient movement through three-dimensional space along all six degrees of freedom is also provided by using a two-dimensional pointing device, preferably a mouse, in combination with a function selector, preferably a pair of keys on the mouse. Use of the mouse without the function selection keys allows movement in a first plane in the three-dimensional space rendition, and use of the mouse in combination with the first function selection key allows movement in a second plane in the three-dimensional space rendition. Use of the mouse in combination with the second function key allows rotation in three-dimensional space rendition. Preferably, the six degrees of movement are implemented using predetermined combinations of mouse movement and function key selection to provide user intuitive movement through the three-dimensional space rendition along all six degrees of freedom.
