An apparatus, system and method for providing spot lighting for observing a gemstone is presented. In particular, the spot lighting provided by the invention allows for observing of the fire of a gemstone, i.e. the visible effects of light dispersion into separate colors. The apparatus includes a tube for receiving a portion of a multi-spectral light source, and a mask coupled to the tube for blocking other portions of the light source. By selecting the proper tube dimensions and aligning the tube with both the light source at an inlet and a gemstone at an outlet, the spot lighting source provides direct lighting for isolating and accentuating the effects of fire.

A first embodiment of the present invention comprises a fully functional portable computer with central processing unit, hard disk drive data storage, and liquid crystal display and a docking station having at least a floppy disk drive, video random access memory and video controller. A motorized docking/undocking mechanism automatically docks and undocks the portable computer and docking station after the user has inserted the portable computer into the docking station or after the user has requested that the units be undocked. Numerous mechanical and electrical safeguards prevent the docking or undocking of the units if such docking or undocking is likely to lead to the loss of data or damage to the components of either unit. The internal mechanical construction of the docking station allows the user to place a large cathode ray tube display monitor directly atop the docking station without hindering the docking or undocking of the portable computer.

The gurney cover and optional heating system comprises a container, a body cover spool, a body cover, a head cover spool, a head cover, a plurality of container clips, one or more body cover clips, and one or more head cover clips. The container may couple to a first side of a gurney via the plurality of container clips. The body cover and the head cover may be adapted to be deployed from within the container by pulling them across the gurney to cover a patient. The body cover may couple to a second side of the gurney via one or more body cover clips. The head cover may couple to the second side of the gurney via one or more head cover clips. The body cover, the head cover, or both may comprise battery-powered heating elements that are adapted to warm the patient.

Recombinant Factor IX characterized by a high percentage of active protein can be obtained in the milk of transgenic animals that incorporate chimeric DNA molecules according to the present invention. Transgenic animals of the present invention are produced by introducing into developing embryos DNA that encodes Factor IX, such that the foreign DNA is stably incorporated in the DNA of germ line cells of the mature animal. Particularly efficient expression was accomplished using a chimeric construct comprising a mammary gland specific promoter, Factor IX cDNA that lacked the complete or any portion of the 5′-untranslated and 3′-untranslated region, which is substituted with a 5-′ and 3′-end of the mouse whey acidic protein gene. In vitro cell cultures of cells explanted from the transgenic mammal of the invention and methods of producing Factor IX from such said culture and methods of treating hemophilia B are also described.

A system and technique for generating a graphical representation of a gemstone is used to generate a scaled profile view of a gemstone representation. The scaled gemstone graphic includes a first portion that contains scaled graphical representations of facets and a second portion that contains no facets. The gemstone graphic is scaled in accordance with a set of cut proportions obtained for the gemstone representation. The gemstone graphic can be rendered for printing or display in connection with a gemstone grading report.

Of the “four C's,” cut has historically been the most complex to understand and assess. This application presents a three-dimensional mathematical model o study the interaction of light with a fully faceted, colorless, symmetrical round-brilliant-cut diamond. With this model, one can analyze how various appearance factors (brilliance, fire, and scintillation) depend on proportions. The model generates images and a numerical measurement of the optical efficiency of the round brilliant-called DCLR—which approximates overall fire. DCLR values change with variations in cut proportions, in particular crown angle, pavilion angle, table size, star facet length, culet size, and lower girdle facet length. The invention describes many combinations of proportions with equal or higher DCLR than “Ideal” cuts, and these DCLR ratings may be balanced with other factors such as brilliance and scintillation to provide a cut grade for an existing diamond or a cut analysis for prospective cut of diamond rough.

摘要:
An optically addressed, optical relaying device placed between crossed polarizers utilizes an array of pixels made up of photodetectors, circuitry, and modulating pads, and an analog liquid crystal to modulate the intensity of an optical signal on a pixel by pixel basis. The photodetector generates a current proportional to the light detected. Once the current exceeds a certain level, the circuitry stores a charge on the modulating pad proportional to the photo-induced current. This stored charge rotates the molecules of the liquid crystal thereby rotating the polarization of the light signal. The output polarizer then attenuates the light beam according to the change in polarization.

The beverage container cover is a disposable security cover that is placed over an open beverage container that contains a beverage. The beverage container cover is placed over the open beverage container for the purposes of: 1) protecting the contents contained within the open beverage container from being tampered with while the open beverage container is unattended; 2) provide a visual indication that indicates that an attempt was made to tamper with the contents contained within the beverage container. The beverage container cover comprises a shell and a locking mechanism. The shell is wrapped around the beverage container to prevent tampering with the contents of the beverage container. The locking mechanism is a permanent lock that once engaged cannot be disengaged. The beverage container cover is removed by removing a perforated tab that is formed within the shell of the beverage container cover.
