摘要:
The present invention includes an adjustable head set held in place on the back of a patient's head when the patient leans back against a chair head rest. The head set includes self-preparing disposable monitors that provide good contact with the patient's head without prior skin preparation. The monitors include a conductive tube containing conductive wires, the tips of which form a planar cushion surface for contacting thr patient's head through a caratinaceous layer of skin. The monitors are held in adjustable holders that allow the contact force to be adjusted. The adjustable holders are mounted in holder slots of head set springs where the slots also allow adjustment of the placement of the monitors. The springs can include hinges for rotatably adjusting placement of the monitors. The disposable monitors are filled with an electrolyte solution using a disposable applicator including a puncturable film, punctured by a monitor when the electrolyte solution is being applied.

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 network for managing account addresses (such as for credit card accounts) where correspondence and other communications mailed to account holders may have different purposes (e.g., credit card statement, new credit card, marketing correspondence). The network has a database for storing addresses and a database management system for retrieving those addresses. A default address is provided when there is no address stored in the database for the intended purpose of a mailing. The addresses are in categories, with each category associated with a different communication purpose, and with multiple addresses in each category. The multiple addresses within each category may be permanent, temporary or repeating. If temporary or repeating, effective start and end dates are associated with the addresses. There may be multiple cardholders for each account, in which case the address categories (and multiple addresses within each category) are associated with each cardholder.

An LCD projection system, located within a standard color CRT, is used to oject toward the screen decay stimulation patterns that vary dynamically from one frame to the next for each pixel based on the video signals received from external sources. This controls the output light intensity of the phosphors that are excited by a single electron gun. This system eliminates the three-electron-gun configuration of the standard CRT as well as the requirement of a shadow mask. What results is a CRT that is more rugged, easier to manufacture and that produces brighter and sharper images on its screen.

The present invention provides a method of obtaining an organism which has been characterized as having cells containing exogenous genetic material which includes any sequence of DNA that can be distinguished as exogenous by known molecular biological analysis by insertion of genetic material into an animal's genetic makeup. The insertion of the genetic material is done by inserting DNA that has been complexed with molecules that allow the DNA to be inserted into the chromosomes when injected into the cytoplasm, perivitelline space, or placed in surrounding culture media to be taken up and incorporated into the genome. When the DNA is complexed into the polyelectrolyte molecules by electrostatic attraction, the electric charge of DNA of the complex is partially to substantially neutralized. The present method does not require the genetic material to be introduced into the embryo at a particular stage in development.

An optical scanning device for mechanically scanning images at a high scanate over a wide field of view and under low light conditions. The device comprises a first rotating reflecting means such as mirrors for intersecting an input beam of light in a first path and for redirecting the beam of light into a second path. A second rotating reflecting means intersects the second path and reflects the beam of light into a third path, onto a detecting device for detecting the presence of predetermined images in the beam of light. In order to reflect the light beams over an elliptical path the mirrors are mounted on rotating shafts at a slight angle from the perpendicular to the axis of the rotating shaft. The mirrors are rotated at varying speed relationships to each other and varying phase relationships to each other in order to produce a variety of scan patterns.

A regulator is provided in which the bias which urges the unseating of the regulating valve is a piston having a plurality of radial working surfaces, each in its own separate pressure chamber. The chambers are connected to the inlet selectively, singly or in combination, by solenoid valves. The unseating of the regulating valve is opposed by the outlet pressure which works on the entire back side of the piston. In the preferred form a relationship exists between the relative sizes of the individual piston working surfaces so that all the possible outlet pressures attainable by the regulator are equispaced, all the way from 0 psig to the highest regulated pressure.

A laser position sensor system for viewing a wide field of view for detecting the angular position of a remote laser. A laser beam directed toward the sensor from any position within a 90 degree circular field-of-view can be detected to a positional accuracy of less than 0.1 degree in a two-axis coordinate system. The system utilizes two parallel sensors having field-of-view optics that compress the field-of-view. The compressed output from each optics is directed through a polarizer and filter to a phase shifter. The phase shifter, a pair of birefringent crystals, encodes the angle of incidence of the laser beam as a phase shift between the two components of the polarized input beam. These components, the e-ray and the o-ray travel different paths through the phase shifter. Subsequently, an analyzer such as a Wollaston prism decomposes the beam into two linear components. These components are condensed through a reimager lens and coupled to a pair of intensity detectors. The detector outputs from each sensor can then be combined to provide a normalized signal proportional to a trigonometric function of the angle of incidence of the laser beam, indicative of its position in space.
