20100041066 | NON-PRECIPITATING BODILY FLUID ANALYSIS SYSTEM - A bodily fluid analyzer including a dry test strip impregnated with a reagent providing a non-precipitating reaction to exclude non-desired analytes. The reagent complexes the non-desired analytes so they remain in solution but cannot participate in the test reaction. Red blood cells are removed from the detection area by slowing their vertical movement and stopping flow when the detection membrane is saturated. | 02-18-2010 |
20100205797 | APPARATUS AND METHOD OF MANUFACTURING BODILY FLUID TEST STRIP - There is a dry test strip holder having a test port and a retainer defining a well about the test port, and a sheet of test strip material. A test element that is 50% or less greater than the size of the test port is cut from the sheet using a die and punch. The punch drives the test element through a channel in the die while the cone-shaped outer surface of the die spreads the retainer, allowing the test element to drop into the well. A cap is snapped over the retainer to capture the test element. | 08-19-2010 |

20100191718 | COMPLEX RELATIONAL DATABASE EXTRACTION SYSTEM AND METHOD WITH PERSPECTIVE BASED DYNAMIC DATA MODELING - The present invention involves a computer for implementing a complex database management system. A processor has at least one complex database with extraction software. The database extraction software is capable of creating a perspective based data model from a user selected data table of the database. A query is specified by user selection of attributes from a data table of the database. A perspective based data model is created from the user selected data base table of the database and related tables. The extraction software creates a query structure defining a plurality of paths providing a selected portion of the information in the database, which is presented to the user based on the perspective based data model. The query structure defines a plurality of paths and having a plurality of nodes, each of the nodes having a corresponding operand. A downward evaluation of the query structure is performed, proceeding from a starting object down downwardly through the paths. An upward evaluation of the query structure is performed, proceeding upwardly from the bottom of each path. The operands are resolved according to predetermined rules so that the number of evaluations of the nodes is less than the number of instances of each operand in the query structure. | 07-29-2010 |
