Patent number: 4748600Abstract: An interactive drug dispenser which actively controls the pattern in which doses of one or more pharmaceutical preparations are administered to a patient. The dispenser is programmed with information concerning an initial dosing regimen, and monitors deviations from that regimen. The dispenser is adapted to calculate from the dosage deviation a dosing error correction factor which corrects a patient's measured plasma drug concentration for deviations from a prescribed dosing regimen, so as to distinguish the effects of patients' dosing errors from suboptimal prescribed dosage regimens.Type: GrantFiled: July 31, 1987Date of Patent: May 31, 1988Assignee: Aprex CorporationInventor: John Urquhart

Patent number: 4745074Abstract: A blood fluid composition for use in a complement-mediated cell lysis system. The composition includes a blood fluid, which may be either a serum source of complement, analyte-containing serum, or both, and lipid vesicles capable of reducing the extent of non-specific cell lysis produced when the blood fluid is added to lysable target cells in the system. The vesicles are present in an amount which increases the ratio of ligand-specific to non-specific cell lysis in the system at least 2-fold and preferably 4-fold or more over that achievable in the system in the absence of the vesicles.Type: GrantFiled: February 23, 1984Date of Patent: May 17, 1988Assignee: Cooper-Lipotech PartnershipInventors: Hans Schreier, Francis J.

Patent number: 4745186Abstract: The present invention comprises a new class of 2,3,4-tri-O-acylhexoses and mixtures thereof. Members of the new class of compounds are comprised of a hexose sugar having fatty acids attached at the 2, 3 and 4 positions of the hexose moiety. The fatty acids can be saturated or unsaturated, and can have a relative molecular size of up to C.sub.30. When at least one of the acylating fatty acid groups on the hexose molecule contains more than 7 carbons, the resulting 2,3,4-tri-O-acylhexoses (or mixtures thereof) have a non-bitter taste. On the other hand, when none of the acylating fatty acids have more than 7 carbons, the resulting 2,3,4-tri-O-acylhexoses (and mixtures that contain them) are bitter when tasted.The new 2,3,4-tri-O-acylhexoses can be synthesized using known chemical methods. Alternatively, the new compounds, and especially mixtures thereof, are obtained as the result of selective extraction and purification of the epicuticular exudate from Lycopersicon pennellii plant parts.Type: GrantFiled: February 10, 1986Date of Patent: May 17, 1988Assignee: Plant Cell Research Institute, Inc.Inventors: John B.

Patent number: 4743302Abstract: Fluid, stable glasses that are useful for low temperature sealing applications are made by adding jointly bismuth oxide, zinc oxide, and phosphorus pentoxide to the lead oxide-vanadium oxide binary. The phosphorous pentoxide may be replaced partially or entirely with niobium pentoxide and/or tantalum pentoxide. Additives and fillers may be incorporated into the glass composition to enhance the fluidity or adhesive characteristics of the glass, alter its coefficient of linear thermal expansion or make it suitable for die attach application. Group V metal oxides, particularly niobium pentoxide, are preferred fillers for altering the coefficient of linear thermal expansion. Similarly these Group V metal oxides may also be added as particulate fillers to lead borate, lead borosilicate and zinc borate glasses. Silver metal is a preferred filler for making die attach compositions.Type: GrantFiled: January 20, 1987Date of Patent: May 10, 1988Assignee: VLSI Packaging Materials, Inc.Inventors: Maurice E.

Patent number: 4741211Abstract: A machine and method for conveniently dynamically balancing heavy rotational members such as large vehicle wheels is disclosed. The machine employs a horizontal rotatable shaft that is movable vertically so as to align and engage the center of the member as it stands vertically in the ground. Thereafter the shaft is raised vertically until the member clears the ground and is rotatable for balancing. In preferred embodiments the balancing mechanism is manually powered and detachable from the machine's base for transport and the base is constructed with its vertical member angled so as to preload and stress the base by the weight of the member and eliminate play in the base. The machine offers portability and transport advantages.Type: GrantFiled: November 13, 1986Date of Patent: May 3, 1988Inventors: Willy Borner, Bernie F. Jackson

Patent number: 4739645Abstract: A calibration vial is described for storing and calibrating under sterile conditions a blood gas sensor that comprises an optical fiber whose sensing end carries a sensing element, such as a chromophore or fluorophore. The vial contains a calibrating liquid and, in its preferred embodiment, is structured to keep the end of the filter wet and permit fast calibration of the sensor without spillage of the calibrating liquid. The vial has a tubular inner calibration chamber in which the end of the fiber resides and which has a sterile filter-plugged gas inlet in its bottom and an outer concentric calibrating liquid reservoir chamber. The bottoms of the two chambers are interconnected by one or more liquid reflux ports that are positioned such that the gas coming into the bottom of the calibration chamber aspirates liquid from the reservoir chamber into the calibration chamber. This permits rapid mixing and circulation of the liquid upwardly through the calibration chamber.Type: GrantFiled: October 17, 1986Date of Patent: April 26, 1988Assignee: Kelsius Inc.Inventor: Vladimir J. Drbal

Patent number: 4738451Abstract: A multi-player, multi-character video game where the game rules force the players to cooperate in negotiating the maze at least until the characters reach a portion of the maze where a specific objective is located. Certain limited resources to change the attributes of the characters or to increase their longevity are displayed in a maze. The players may compete to obtain possession of these limited resources when the characters have cooperated in their movements sufficiently to move to the location of the limited resources. Cooperation among the characters is forced by forcing all characters active in the game to remain visible in the displayed window. Players may enter the game at any time, and they may leave the game at any time without affecting the status of the game or the status of the other characters in the game. All active players may simultaneously, independently control their characters so long as they do not attempt to move their characters outside the currently displayed window.Type: GrantFiled: May 20, 1986Date of Patent: April 19, 1988Assignee: Atari Games CorporationInventor: George E. Logg

Patent number: 4738932Abstract: A reaginic agglutination test for syphilis-associated antibodies is disclosed. The test uses an antigen reagent that comprises a buffered aqueous suspension of cardiolipin antigen ionically coupled to latex particles via a polypeptide bridge. Positive sera react with the antigen reagent and yield an agglutination pattern characterized by medium to large aggregates. Negative sera yield no agglutinated particles.Type: GrantFiled: December 3, 1985Date of Patent: April 19, 1988Assignee: Advanced Polymer Systems, Inc.Inventor: Kenichi K. Yabusaki
