  • Publication number: 20080072663
    Abstract: A method of extracting and analyzing bodily fluids from a patient at the point of care for the patient is provided. The method comprises establishing fluid communication between an analyte detection system and a bodily fluid in the patient. A portion of the bodily fluid is drawn from the patient. A first component of the bodily fluid is separated from the drawn portion, while the analyte detection system remains in fluid communication with the patient. The analyte detection system analyzes the first component to measure a concentration of an analyte in an accurate and timely manner.

  • Publication number: 20070180264
    Abstract: A case-grounded flash-memory drive has a printed-circuit board assembly (PCBA) with flash-memory chips and a controller chip. The PCBA is encased inside an upper case and a lower case, with a Serial AT-Attachment (SATA) connector that fits through an opening between the cases. The cases can be assembled with the PCBA by a screw-together or thermal-bond adhesive method. Triple-axis case-grounding tabs draw any electro-static-discharges (ESD) current off the upper case along a primary axis and onto a PCBA ground through a secondary axis that is screwed into the PCBA. An intermediary axis between the primary and secondary axes fits around a PCBA notch while the secondary axis passes through a metalized alignment hole on the PCBA for grounding. When the SATA connector is inserted into a host, the host ground sinks ESD currents collected by the triple-axis case-grounding tabs.

  • Publication number: 20050264815
    Abstract: A sample element configured to hold a material sample for determining a concentration of an analyte in the material sample. The sample element comprises a first window, a sample chamber partially defined by the first window, and a second, moveable window substantially aligned with the first window and the sample chamber. The second window is moveable from a first position in which the second window is spaced from the sample chamber, to a second position in which the second window covers and at least partially encloses the sample chamber.

  • Publication number: 20050250217
    Abstract: Disclosed is a sample element for use in analyzing a concentration of an analyte in a material sample. The sample element comprises a sample chamber having at least one window, and a supply passage extending from the sample chamber. The supply passage defines a supply axis. The sample element further comprises a vent opening in fluid communication with the sample chamber. The vent opening is offset from the supply axis as the sample element is viewed orthogonal to the window.

  • Publication number: 20050036146
    Abstract: A sample element includes first and second substantially parallel faces separated by an intermediate member. The parallel faces and the intermediate member at least partially define a sample chamber configured to hold a volume of fluid. The sample element further includes an optical path extending through the parallel faces and the intermediate member, such that electromagnetic radiation can propagate through the sample chamber. The sample element further includes an identifying compound disposed within or on at least one of the parallel faces. The identifying compound has at least one indexed optical absorbance feature, such that spectral analysis of electromagnetic radiation propagated through the sample chamber yields the indexed optical absorbance feature. Detection of the indexed optical absorbance feature in electromagnetic radiation propagated through the sample chamber indicates to an analyte detection system whether the sample element is configured for use with the analyte detection system.

  • Publication number: 20030122081
    Abstract: An analyte detection system for non-invasively determining the concentration of an analyte in a sample is described. The detection system includes a window assembly consisting of a main layer adapted to allow electromagnetic radiation to pass therethrough, and a heater layer adapted to exchange heat to the sample. The system also includes a detector adapted to detect electromagnetic radiation emitted by the sample and passed through the window assembly. The analyte detection system also includes a control system in electrical communication with the heater layer and adapted to cause the heater layer to exchange heat to the sample. The main layer of the window assembly may be made from a variety of materials such as germanium, silicon, and chemical vapor deposited diamond.
