Abstract:
A body fluid is collected for testing for an analyte contained within the body fluid. The fluid is collected in an apparatus including a reservoir for receiving and collecting a flow of body fluid from a discharge end of a conduit. A capillary test space is in fluid flow communication with the reservoir. The capillary test space is positioned to be in contact with the fluid in the reservoir after the fluid has accumulated to a predetermined transfer volume of fluid. The capillary test space is sized to wick the fluid from the reservoir when the fluid contacts the capillary test space.

A compressor diffuser for a vehicle engine turbocharger, the diffuser comprising: a diffuser housing having a gas flow path having a side wall connecting a gas inlet to a gas outlet; a plurality of pivotally mounted diffuser vanes arranged in the flow path to control gas flow, and a vane angle control device for adjusting the angle of each of the plurality of vanes in the flow path; the control device comprising a unison ring coupled to the plurality of vanes in such a way that rotation of the unison ring pivots each of the vanes by interaction of a cam surface with a respective cam follower.
Abstract:
A method for use in a system for diagnosing the causes of manufacturing defects involves process characterization. A set of forms is identified for a workpiece and for a piece of manufacturing equipment that acts upon the workpiece. The forms for the workpiece are preferably a hierarchic set of geometric forms. Each such geometric form corresponds to an aspect of the action of the manufacturing equipment upon the workpiece. A plurality of measurements is made on a defective workpiece following the hierarchical order of forms. The measurements are compared to a reference datum, and a deviation from the datum is computed. If the deviation exceeds a preselected threshold, an alert condition results, attributable to the action of the manufacturing equipment. Targeted adjustment corresponding to the action that caused the defect can then be made to the equipment.
Abstract:
A computer is programmed to emulate a fixed-point operation that is normally performed on fixed-point operands, by use of a floating-point operation that is normally performed on floating-point operands. Several embodiments of the just-described computer emulate a fixed-point operation by: expanding at least one fixed-point operand into a floating-point representation (also called “floating-point equivalent”), performing, on the floating-point equivalent, a floating-point operation that corresponds to the fixed-point operation, and reducing a floating-point result into a fixed-point result. The just-described fixed-point result may have the same representation as the fixed-point operand(s) and/or any user-specified fixed-point representation, depending on the embodiment. Also depending on the embodiment, the operands and the result may be either real or complex, and may be either scalar or vector. The above-described emulation may be performed either with an interpreter or with a compiler, depending on the embodiment. A conventional interpreter for an object-oriented language (such as MATLAB version 6) may be extended with a toolbox to perform the emulation. Use of type propagation and operator overloading minimizes the number of changes that a user must make to their program, in order to be able to use such emulation.
Abstract:
A medical device package for receiving, and securely and removably retaining, a medical device includes main and minor cap members. The main cap member has a proximal end, a distal end and a cavity with a cavity opening at the proximal end. The cavity is configured to receive, and to securely and removably retain, the medical device at least partially therein. The minor cap member is configured to seal the cavity opening once the medical device has been received in the cavity. Kits further include a connector adapted for engaging the medical device member and breaching the minor cap member. A method for extracting a medical device from a medical device package includes first providing a medical device package as described above, with a medical device therein, and a connector. The method also includes breaching the minor cap member with the connector such that at least a portion of the connector enters the cavity of the medical device package. Next, the medical device is engaged by the connector and extracted from the medical device package.
Abstract:
A packaged medical device includes upper and lower flexible sheets, a lance body and a test strip. The lance body includes upper and lower surfaces, an opening that extends between the upper and lower surfaces and a dermal tissue penetration member that projects into the lance body opening. The test strip has an opening therethrough and is attached to the lance body lower surface such that the dermal tissue penetration member is operatively aligned with the test strip opening. The upper flexible sheet is attached to the lance body upper surface and covers the lance body opening, while the lower flexible sheet is detachably attached to the test strip and covers the test strip opening. The upper flexible sheet, lance body and test strip are configured such that, when the lower flexible sheet has been detached to uncover the test strip opening, the upper flexible sheet, lance body and test strip can be bent to deploy the dermal tissue penetration member from the lance body opening. A kit includes the packaged medical device described above and a deployment device for detaching the lower flexible sheet and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member. A method for deploying a dermal tissue penetration member of a packed medical device includes providing the packaged medical device described above, detaching the lower flexible sheet to uncover the test strip opening and bending the upper flexible sheet, lance body and test strip to deploy the dermal tissue penetration member.
Abstract:
The present invention provides a method and apparatus for handling tubulars and drilling with tubulars such as casing into a formation. In one aspect of the invention, the apparatus comprises a circulating head and a cementing head operatively connectible to a gripping member. The circulating head is used to circulate drilling fluid while drilling with casing, and the cementing head is used to cement the casing string within the formation at a desired depth. The present invention also relates to methods and apparatus for isolating a tensile load from a drilling apparatus rotated by a top drive. In one aspect, the present invention provides a load isolator apparatus having an isolator body operatively connected to the top drive and a torque body at least partially disposed in the isolator body. In operation, the bearing assembly transfers the tensile load from the torque body to the isolator body.
Abstract:
A double containment pipe fitting and method of making same is disclosed. The fitting includes a branch double containment pipe section butt welded to a double containment pipe header, or main section to form a fitting wherein the branch section extends away from the header section. The header and branch section primary and secondary pipe portions contain distinct engagement surfaces which are joined together to form the fitting. A unique, non-planar heating element having opposed heating surfaces is brought into contact with the main and branch pipe sections to soften the plastic for welding purposes which are then joined together in a manner such that the respective centerlines of each pipe section intersect.
