Patent number: 8652037Abstract: A data collection system is formed from an analyte detection meter and a base station. The meter and the base station are operatively connected to one another to transfer data from the meter. The base station is able to communicate transferred data to a data receiving server, and the transfer of data occurs in response to a defined stimulus such as the proximity of the meter and base station or an alarm set at a predetermined time of day. The data collection system can be used in combination with a system interface that provides a data management system (DMS) resident on a device such as a personal computer. The DMS can recognize a particular meter and may incorporate into the displayed information not only the data resident on the meter but also information previously transferred from the meter. The DMS may be launched on the computer as soon as connection with a meter is detected.Type: GrantFiled: June 8, 2006Date of Patent: February 18, 2014Assignee: AgaMatrix, LLCInventors: Neel Bakarania, Joseph Flaherty, Timothy Golnik, Robert F.

Patent number: 8591722Abstract: A method is provided for determining analyte concentrations, for example glucose concentrations, that utilizes a dynamic determination of the appropriate time for making a glucose measurement, for example when a current versus time curve substantially conforms to a Cottrell decay, or when the current is established in a plateau region. Dynamic determination of the time to take the measurement allows each strip to operate in the shortest appropriate time frame, thereby avoiding using an average measurement time that may be longer than necessary for some strips and too short for others.Type: GrantFiled: August 9, 2011Date of Patent: November 26, 2013Assignee: AgaMatrix, Inc.Inventors: Steven Diamond, Ian Harding, Sridhar G.

Patent number: 8030942Abstract: An electrochemical cell has two terminals. One of the terminals is connected to a pulse-width-modulated (PWM) power supply and to a voltmeter. The other terminal is connected to circuitry capable of switching between amperometric and potentiometric measurement modes. A sequence of successive approximations permits selection of a PWM duty cycle giving rise to a desired voltage at the terminal connected with the power supply. In this way a stable excitation voltage is supplied to the cell even in the face of supply voltage instability or drift or instability in electronics coupled with the cell.Type: GrantFiled: November 8, 2007Date of Patent: October 4, 2011Assignee: Agamatrix, Inc.Inventors: Steven Diamond, Martin Forest, Baoguo Wei

Publication number: 20100308837Abstract: A test strip and analytical apparatus have pin connections permitting the definition of geographic regions or of particular customers. A test strip made for use in a particular region or for a particular customer will have pin connections matching features of the apparatus made for use in that region or by that customer. Insertion of the strip into the apparatus does not merely turn on the apparatus, but provides the regional or customer coding. Analog switches within the apparatus allow coding of a larger number of distinct regions or customers than would otherwise be possible, all without degrading the quality of the measurements made of the fluid being tested. Conductive paths in the strips permit testing the strips during manufacture so as to detect quality lapses regarding the printing or deposition of the paths.Type: ApplicationFiled: May 11, 2010Publication date: December 9, 2010Applicant: AGAMATRIX, INC.Inventors: Steven Diamond, Martin Forest, Baoguo Wei, Ian Harding, Sridhar Iyengar

Publication number: 20090095623Abstract: The present invention provides a method and apparatus for creating test strips that may be identified based on differences in electrical conduction or resistance between contact point on the test strip. This is achieved by creating a base test strip with contact points that may be connected to other contact points by an electrical connection. These base test strips may be modified to create a difference in electrical conductivity between contact points, or a contact point may be eliminated. This modification can be used to distinguish different types of test strips based on electrical signature. Additionally, the base test strip may be created such that multiple modifications are possible to distinguish numerous characteristics of test strips.Type: ApplicationFiled: October 9, 2008Publication date: April 16, 2009Applicant: AGAMATRIX, INC.Inventors: Charles Boiteau, Martin Forest, Sridhar Iyengar, Baoguo Wei
