  • Patent number: 7967127
    Abstract: The present invention relates to an adjustable star wheel and guide rail assembly for use with containers being processed on an automated handling line between machines such as rotary packaging machines. Star wheels derive their name from their general shape. The star wheels of this invention have fingers that support containers, such that they convey the containers as the star wheel rotates. Conveniently, the fingers of the present invention may be set in any position within their range of movement. In addition, a supporting guide rail may be adjusted, for example by rotation on cams. Thus, the fingers and the guide rail may be set to convey containers of varying sizes while keeping the container's centers travelling along the centerline of the conveyor.

  • Patent number: 7892752
    Abstract: One can identify and quantify one or more glycosylation markers of cancer by utilizing quantitative HPLC analysis of glycans which have been released from unpurified glycoproteins. The unpurified glycoproteins can be total glycoproteins or a selection of the total glycoproteins. The identified glycosylation marker can be a native glycan or a digestion product which has been segregated and amplified by exoglycosidase digestions. One can utilize the identified glycosylation marker, for example, for diagnosing and/or monitoring cancer in a subject. One can also use the glycosylation marker to identify glycoprotein biomarkers that carry the glycosylation marker. Such biomarkers can also be used for monitoring and/or diagnosing cancer. The biomarker may also be a subset of glycoforms of a glycoprotein that are separated in trains of spots on 2D gel.

  • Publication number: 20100239861
    Abstract: A first method comprises: dissolving a polymer in a terpene, terpenoid, or aromatic solvent to form a polymer solution; dissolving a salt in a polar organic solvent to form a salt solution; and mixing the salt solution and the polymer solution to form a mixture. The salt and the polar organic solvent do not cause substantial precipitation of the polymer upon mixing with the polymer solution. A resulting terpene, terpenoid, or aromatic solvent phase of the mixture is suitable for forming fibers by electric-field-driven spinning from one or more spinning tips onto a target substrate. A composition comprises the terpene, terpenoid, or aromatic solvent phase of the mixture resulting from the method. A second method comprises forming fibers by electric-field-driven spinning of the first composition from one or more spinning tips onto a target substrate. A second composition comprises the fibers formed by the second method.

  • Patent number: 7755685
    Abstract: A pixel for an imager is disclosed that includes at least one electron multiplication (EM) gain stage configured in a loop and electrically coupled to a charge collection region and a charge readout region, the charge collection region being configured to generate a charge packet, the EM gain stage being configured to amplify the charge packet by impact ionization and to circulate the charge packet a predetermined number of times in one direction around the loop, the charge readout region being configured to receive the amplified charge packet and convert the amplified charge to a measurable signal. The at least one EM gain stage, the charge collection region, and the charge readout region can be formed monolithically in an integrated circuit. The pixel can be manufactured using a CMOS process. The pixel can further include a second EM gain stage formed in the integrated circuit to increase the amount of amplification around the loop.

  • Patent number: 7748523
    Abstract: An automated handling line guide rail assembly. The automated handling line guide rail assembly comprises a guide rail that defines the perimeter of a path of a container when conveyed along part of an automated handling line. The path and hence the perimeter are arcuate about a center and positioned at a radius from the center. The guide rail is movable radially to define the perimeter at a plurality of different radii from substantially the same center and the guide rail comprises at least three segments. The first segment is driveable in a substantially radial direction; the second segment is connected to the first segment by a link and the third segment is connected to the second segment by a link such that the second and third segments follow movement of the first segment.

  • Publication number: 20100071619
    Abstract: An electrohydrodynamic spraying or spinning deposition system, which includes a common source of pressurized liquid within a manifold, and an array of 2 or more spraying tips, each tip being fed from the common source of pressurized liquid to create a liquid flow path. An individual flow impedance device is disposed within each tip's individual liquid flow path from the pressurized liquid source into each spraying tip. The individual flow impedance devices are disposed within a replaceable sheet, which can be easily cleaned or changed to accommodate the instance liquid viscosity and composition. A high voltage source is applied to create a high voltage potential applied between the tip array and a deposition surface.

  • Publication number: 20100013859
    Abstract: Disclosed is the presentation of text data on a high-resolution display screen using an image, which includes nonlinear (3D) surface undulation and viewing perspective. This presentation results in variations of character size, rotation, and aspect across the screen. Additionally, positional cues, and coloration gradations may be added. As will be shown, all of this assists human readability and reduces fatigue.

  • Publication number: 20090318539
    Abstract: A process for preparing a particle comprising a biological molecule typically a DNA plasmid, and a carrier polymer, typically poly-lactic acid (PLA), in which an organic solvent solution of the biological molecule and the carrier polymer in an organic solvent medium, nearly saturated with the biological molecule, is prepared, then this solution is contacted with an antisolvent substance, typically supercritical carbon dioxide to separate a particle comprising the biological molecule and the carrier polymer. High loadings of the biological molecule in the particle can be achieved.

  • Patent number: 7565547
    Abstract: A system and method for providing ad hoc controlled user access to wireless and wireline IP communication networks while maintaining privacy for users and traceability for network providers. The method includes an authentication interface accepting user credentials, and a validation entity for credential verification and access authorization. The credentials include a unique identifier and a system generated password. The unique identifier is associated with a personal entity of the user such as a cellular telephone. The password is transmitted to the user through a SMS message to his cellular telephone. The user's Internet session is monitored by the system and all records are indexed by his cellular telephone number. The system and method therefore permit fast and traceable access for guest users at networks where they are were not previously known. Alternatively, users do not provide their unique identifiers such as cellular telephone numbers which are instead already stored in the system.
