Title: Method and apparatus for aligning telescopes within a free-space optical communication system
Inventor: PRESBY HERMAN MELVIN
IPC: H04B10/118
Filed: 2001-09-24
Abstract: A free space optical communication system is disclosed whereby a transmit telescope and a receive telescope are aligned such that the point of maximum power of the received light beam is incident upon the optical fiber located at a specific point on the focal plane of the receive telescope. Such incidence is achieved by causing the transmitted beam to diverge by moving the transmit optical fiber to a point in front of the focal plane of the transmit telescope until at least a portion of the beam is incident upon the receive optical fiber. The transmit telescope and/or the receive telescope (or, alternatively, only the respective optical fibers of those telescopes) are then moved such that the point of maximum received power for that degree of divergence is incident upon the receive optical fiber. The transmit optical fiber, in response to received power measurements at the receive telescope, then incrementally moves back toward the focal plane of the transmit telescope thereby reducing the degree of divergence and achieving a greater signal per unit area at the receive telescope. As the divergence is reduced, the position of the either the transmit telescope and/or the receive telescope (or, respectively, the optical fibers) is incrementally adjusted to maximize the received power of the received signal which is incident upon the receive optical fiber for each degree of divergence. By monitoring received signal power this iterative process continues until the transmit and receive telescopes are aligned such that the transmitted beam is focused so as to maximize the received power that is incident upon the receive optical fiber.

Title: Microwaveable sponge cake
Inventor: MCPHERSON ANDREW E
IPC: A21D13/08
Filed: 2001-10-03
Abstract: The present invention relates to microwaveable sponge cakes, which when heated in a microwave oven, rise in a manner similar to conventionally-baked sponge cakes. Such sponge cakes are mesophase gel- containing. Moreover, such mesophase-containing sponge cakes, when microwaved, do not only rise as is observed with conventional sponge cakes, but microwave treatment of these sponge cakes results in highly palatable and light sponge cakes, similar to those that are conventionally prepared. The mesophase gels formed herein for use in sponge cake are highly viscous, even in the absence of polymeric protein or polysaccharide thickening or bulking agents. The mesophase gels is formed using two emulsifiers and an aqueous phase. The addition of the mesophase gel to the other sponge cake components results in a leavening action, and contributes to the palatability and lightness of the resulting sponge cake.

Abstract: Shaped rigid board insulation used in conjunction with structural frame members chosen for preferred qualities used in the system innovatively provides advantages in the manufacture ,assembly and performance of structural insulated panels for walls , roofs and floors of buildings. The structural panels maybe assembled in a factory or field assembled. The physical properties of shaped rigid board insulation make it the more preferred material choice than fibreglass bat insulation in achieving the ultimate strength and thermal value in a structural frame panel system. Rigid board insulation physical properties make it ideal for cutting and shaping using simple hand tools or simple machines that are readily available. Cutting rigid board insulation into such shapes as triangles, rectangular, squares and shaping on one or both faces or one or both sides provides one of the components required in the panel assembly system and jigging system for the manufacture and assembly of structural framed insulated panels using shaped rigid board insulation. The selection of some preferred materials used for structural frame members include steel, reinforced fibreglass, reinforced plastic and aluminum. In the manufacture of preferred structural frame members using steel, reinforced fibreglass, reinforced plastic or aluminum complex shapes are required to enhance the materials physical properties.  Preferred manufactured structural frame members can be made to exacting tolerance and cut to exacting tolerance. Sliding shaped rigid board insulation inside manufactured structural frame members stops the structural frame members from deforming which is preferred comparing to forcing rigid board insulation into structural frame members. Preferred manufactured structural frame members cut to exacting tolerance are preferred structural framing components used in the manufacture, assembly system and jigging system of shaped rigid board structural panels. Shaped rigid board insulation friction fitted into structural frame members allows the structural frame to be more ductile compared to foam injected panels or panels that require structural adhesive to bond the board insulation in place. In a shaped rigid board insulated structural panel building system with preferred structural frame members, with perimeter frame members and interior frame members or just perimeter frame members , the frames structural strength will be greatly enhanced by the rigidity of the shaped board insulation supporting the frame both vertically and horizontally and will have continuity of insulation and better overall performance.

Inventor: INSULL WILLIAM JR
IPC: A61B5/0295
Filed: 2000-03-24
Abstract: The calibrated method for characterizing blood flow in a limb of a patient during reactive hyperemia utilizes a blood pressure cuff (14). The method establishes a predetermined, near diastolic, pressure in the blood pressure cuff (14) during the reactive hyperemic episode, continually senses via a sensor (68) the pressure in the cuff, and periodically changes the internal volume of the blood pressure cuff by a predetermined volumetric amount to calibrate the system. The resultant change in the pressure is a calibration pressure pulse (P-cal), and is used to calculate pulsatile blood volume through the blood vessel. A calibrated method for determining the condition of blood vessels, and endothelium includes determining, for each calibration cycle, a respective peak value (t-P) for the blood volume, and comparing the peak blood volume values with peak blood volume values for healthy blood vessels, and endothelium. The comparison preferably utlizes a waveform (W1).

Title: Detection of chromosome copy number changes to distinguish melanocytic nevi from malignant melanoma
Inventor: PINKEL DANIEL
IPC: G01N33/566
Filed: 2000-04-10
Abstract: The present invention provides for methods of distinguishing melanocytic nev i, such as Spitz nevi, from malignant melanoma. The methods comprise contacting  a nucleic acid sample from a patient with a probe which binds selectively to a  target polynucleotide sequence on a chromosomal region such as 11p, which is  usually amplified in Spitz nevi. The nucleic acid sample is typically from skin tumor cells located within a tumor lesion on the skin of the patient. Using another probe which binds selectively to a chromosomal region such as 1q, 6p, 7p, 9p, or 10q, which usually show altered copy number in melanoma, the method can determine that those tumor cells with no changes in copy numb er of 1q, 6p, 7p, 9p, or 10q, are not melanoma cells but rather Spitz nevus cells. The finding of amplifications of chromosome 11p, particularly the presence of an 11p isochromosome would be an additional indication of Spitz nevus. An increase in copy number of chromosome 11p can also be determined b y detecting the presence of an amplification of the H-RAS gene. The amplified gene can be normal or can be a mutated H-RAS gene.
