  • Patent number: 7976466
    Abstract: Embodiments of the present invention improve the accuracy of measurements and/or in vivo calibrations of a biosensor by (1) using more than one sensor signal value and/or more than one directly sampled and measured value, such as a capillary blood glucose value, and/or by (2) delaying the acquisition of a sensor output value that is compared with a directly sampled and measured value, such as a capillary blood glucose value, during a calibration. In an embodiment of the present invention, the median of a series of measured values, or a median or mean of the medians, may be utilized to provide more consistent and accurate measurement data and/or to compensate for error or artifact.

  • Publication number: 20110090275
    Abstract: One aspect is a drop detection arrangement including a light source for projecting a light beam for scattering light off of an ejected drop. The arrangement includes a light collector configured to collect the scattered light off the ejected drop and configured to process scattered light into an output signal. The arrangement includes a controller configured to receive the output signal from the light collector, to calculate the velocity of the ejected drop and to determine the volume of the ejected drop using the output signal and the velocity of the ejected drop.

  • Publication number: 20110056264
    Abstract: Embodiments provide a method and related systems that take into account the difference between a measured glucose value and the calibration level and the amount of elapsed time since the prior calibration. As one or both of these determined differences increases, the desirability of an additional calibration also increases. The methodology described herein thus analyzes the combination of change in glucose level as well as the time since the prior calibration. If the combination exceeds a predetermined value, the system recommends, but does not require, that the subject user perform an additional calibration.

  • Patent number: 7862519
    Abstract: A multiple use analyte sensing assembly that includes a long, thin conductor. A plurality of sensing sites are spaced along the conductor and each sensing site includes a membrane system adapted to create a current when placed into contact with body fluid containing the analyte. The assembly also includes a housing, having an aperture, an uptake spool and a payout spool, the conductor being wrapped about the payout spool before the sensing assembly is used. A sensor positioning actuator turns the uptake spool to move each sensing site, in sequence, to the housing aperture and then to the uptake spool. The assembly also includes a skin broaching assembly, having a multiplicity of lancets and a lancet positioning actuator adapted to move each lancet to the aperture. In addition, a lancet use actuator is adapted to move each lancet at least partially through the aperture and then back again.

  • Publication number: 20100265287
    Abstract: In one embodiment, a drop ejector assembly includes a printhead, a drop zone immediately downstream from the printhead, an array of optical fibers exposed to the drop zone such that light scattered off drops in the drop zone illuminates at least some of the optical fibers in the array, and a photo detector operatively connected to the array of optical fibers for converting light from the optical fibers into an electrical signal. In another embodiment, a drop detector includes a light source for illuminating drops passing through a drop zone and a light sensor for sensing light scattered off drops in the drop zone. The length of drop zone is 3 mm or less and the light sensor has a cross sectional dimension less than the length of the drop zone.

  • Publication number: 20100228710
    Abstract: Described is a search technology in which a search engine constructs a results page for a query that integrates suggested queries with the individual query results (e.g., displayed URLs). When rendered, the proximity of the suggested queries to their corresponding individual query result provides context as to the specific URL to which the suggested query is related. Suggested queries may appear alongside their associated search result, e.g., a displayed URL, and/or in an expandable panel proximate that individual search result. Suggested queries may appear within text accompanying a URL, and/or in a drop down menu following interaction with such text or the like. Related queries may be found by using a search result URL to find a query, by analyzing a search result's text snippet, by accessing historical data, and/or by accessing current user session data.

  • Patent number: 7720878
    Abstract: An improved data compression method and apparatus is provided, particularly with regard to the compression of data in tabular form such as database records. The present invention achieves improved compression ratios by utilizing metadata to transform the data in a manner that optimizes known compression techniques. In one embodiment of the invention, a schema is generated which is utilized to reorder and partition the data into low entropy and high entropy portions which are separately compressed by conventional compression methods. The high entropy portion is further reordered and partitioned to take advantage of row and column dependencies in the data. The present invention enables not only much greater compression ratios but increased speed than is achieved by compressing the untransformed data.

  • Patent number: 7687586
    Abstract: Embodiments of the present invention provide various multipolymers and permselective membranes for use with biosensors and other implantable medical devices and prostheses. Embodiments of the present invention may provide structural strength and integrity, and further may control the influx of glucose, oxygen and/or water. Embodiments of the present invention may, for example, minimize or reduce the influx of glucose by minimizing the percentage of hydrophilic segments, which in turn minimizes the percentage of water uptake and the degree of glucose transport.

  • Publication number: 20090313115
    Abstract: A system that facilitates selecting advertisements that match a search query is described herein. The system includes a search query receiver component that receives a search query including keywords. The system also includes a match component that uses an associative data structure to identify in the associative data structure one or more data nodes that are associated in the associative data structure with respective unique keys corresponding to respective one or more hashes of combinations of the keywords in the search query. For each identified data node, the match component selects advertisements associated with bid phrases stored in the identified data node that respectively only include keywords included in the search query.

  • Patent number: 7536366
    Abstract: Systems and methods that enhance estimate(s) of features (e.g., word associations), via employing a sampling component (e.g., sketches) that facilitates computations of sample contingency tables, and designates occurrences (or absence) of features in data (e.g., words in document lists). The sampling component can further include a contingency table generator and an estimation that employs a likelihood argument (e.g., partial likelihood, maximum likelihood, and the like) to estimate features/word pair(s) associations in the contingency tables.

  • Patent number: 7529574
    Abstract: A method of creating an analyte sensor. The method starts with the step of providing an electrochemically active surface. Then, at least one nub made of dielectric material and extending transversely outwardly from the electrochemically active surface is created. A curable liquid is applied to the electrochemically active surface and the nub and is then cured. In this process, the nub, which could be one of several nubs, serves to support the liquid before and during the curing.
