Appl. No.:

09/699157

International Classification:

G06K 936

US Classification:

382242

Abstract:

A method and apparatus for on-the-fly coding digital images using a line scanner, a boundary matcher/follower and a coder, and utilizing a small amount of processing and memory is disclosed. In an on-the-fly digital image coding method and apparatus feature points determining boundaries of regions of adjacent pixels of similar characteristics in each successive scanning line are sequentially detected and efficiently encoded in a chain-link manner, based on information concerned with feature points detected on a preceding scanning line. By this method, additional improvement in compression can be achieved with the use of predictive coding based on spatial stochastic correlation between successive feature points associated with a continuous boundary line. The image coding method of the invention allows a significant reduction of quantity of information needed for image representation without deterioration of image quality and with no requirement of intermediate storing vast amounts of image data at the time of coding.

International Classification:

G02B005/10
F24J002/10

US Classification:

359852, 359853, 126692

Abstract:

A radiant energy collecting and converting device having at least one array of slat-like concave reflective elements and an elongated receiver. The device efficiently concentrates and converts radiant energy, such as sunlight, to other useful types of energy, such as electricity and heat. The mirrored surfaces of reflective elements having appropriate individual profiles represented by curved and/or straight lines are positioned so that the energy portions reflected from individual surfaces are directed, focused, and superimposed on one another to cooperatively form a common focal region on the receiver. The mirrored surfaces are inclined towards one another at their rear ends facing the receiver and can be arranged to provide lens-like operation of the array. The receiver can be arranged in line photovoltaic cells or a tubular solar heat absorber.

US Classification:

126692, 359852, 359853

Abstract:

A radiant energy flux transformation system including a primary linear focus concentrating collector formed by a plurality of cylindrical slat-like reflectors and a secondary elongated collector is described. The reflectors of primary collector generally have concave or planar transversal profiles and are positioned in a stepped arrangement with longitudinal axes being parallel to each other and to the secondary collector. The reflectors are tilted away from the direction to the source of radiant energy at a range of angles being less than 45 to reflect and direct the incident energy flux to a common focal region located below the primary collector where the concentrated flux is intercepted and further transformed by the secondary collector. In addition to efficient concentrating radiant energy such as sunlight, the system can provide uniformity or a desired energy distribution in the concentrated flux.

Abstract:

A light trapping optical cover employing an optically transparent layer with a plurality of light deflecting elements. The transparent layer is configured for an unimpeded light passage through its body and has a broad light input surface and an opposing broad light output surface. The light deflecting elements deflect light incident into the transparent layer at a sufficiently high bend angle with respect to a surface normal and direct the deflected light toward a light harvesting device adjacent to the light output surface. The deflected light is retained by means of at least TIR in the system formed by the optical cover and the light harvesting device which allows for longer light propagation paths through the photoabsorptive layer of the device and for an improved light absorption. The optical cover may further employ a focusing array of light collectors being pairwise associated with the respective light deflecting elements.

International Classification:

H01L025/00

US Classification:

136/246000, 126/569000

Abstract:

A non-imaging energy flux transformation system including a concentrator incorporating a set of nested, ring-like, concave reflective elements, and a receiver. The system efficiently concentrates radiant energy, such as sunlight, by means of focusing the energy striking the entrance aperture of concentrator to the receiver located on the side of concentrator's exit aperture. The mirrored surfaces of reflective elements having appropriate individual non-imaging profiles represented by curved and/or straight lines are positioned so that the energy portions reflected from individual surfaces are directed, focused, and superimposed on one another to cooperatively form a common focal region on the receiver. The receiver can be an energy absorbing device, a secondary energy concentrating transformer, or a flux homogenizer.

International Classification:

G02B 6/32

US Classification:

385 33, 385 36

Abstract:

An apparatus for distributing light from a waveguide through a collimating array, or collecting light over a given area into a waveguide. Light received within a waveguide is propagated transmissively and retained by total internal reflection, except in response to impinging upon deflector elements which sufficiently redirect the light to escape the waveguide into a collimator array that aligns and distributes the light. In a light collector, a collection array collects and collimates the received light and directs it at the surface of a waveguide, within which deflectors properly positioned in relation to each collector of the collector array, deflect the angle of the light so that it propagates through the waveguide in response to total internal reflection. The apparatus can be fabricated into an efficient and compact form.
