Patent number: 7794658Abstract: System, circuits, and methods to reduce or eliminate uncompensated voltage drop between an electrode of an electrochemical cell usable for analyte measurement. In one example, a system is provided that includes a test strip, a reference voltage circuit, an operational amplifier connected to the reference voltage circuit to provide a pre-determined fraction of a reference voltage substantially equal to the test voltage applied to the first line, the operational amplifier having an output configured for one of a connected or disconnected state to the first line, and a processing circuit connected to the output of the operational amplifier and the first line such that, during a disconnected state between the output and the first line, the processing circuit remains in connection with the first line.Type: GrantFiled: July 25, 2007Date of Patent: September 14, 2010Assignee: LifeScan, Inc.Inventors: Mahyar Z. Kermani, Edward Docherty, John McInulty

Patent number: 7593097Abstract: A method for determining a test strip calibration code for use in a meter includes inserting a test strip into the meter. The inserted test strip having a substrate with a working surface for receiving the body fluid sample and a reverse surface that is in opposition to the working surface. The test strip also includes a permutative grey scale calibration pattern disposed on either of the working and reverse surfaces, with the permutative grey scale calibration pattern including more than one grey scale region. Moreover, the scale regions of the test strip define a grey scale permutation that uniquely corresponds to a calibration code of the test strip. The method also includes detecting the permutative grey scale calibration pattern with a grey scale photodetector module of the meter and determining a calibration code that uniquely corresponds to a grey scale permutation defined by the permutative grey scale calibration pattern based on permutation matrix stored in the meter.Type: GrantFiled: May 26, 2006Date of Patent: September 22, 2009Assignee: Lifescan Scotland LimitedInventors: Grenville Arthur Robinson, John McInulty, Damian Edward Haydon Baskeyfield, Thomas J. O'Reilly, Anthony J. Cronshaw

Patent number: 7589828Abstract: A system for measuring an analyte in a body fluid sample includes a meter, with a grey scale photodetector module, and a memory module. The system also includes a test strip. The test strip has a substrate with a working surface for receiving the body fluid sample and a reverse surface that is in opposition to the working surface. The test strip also includes a permutative grey scale calibration pattern disposed on either of the working and reverse surfaces, with the permutative grey scale calibration pattern including more than one grey scale region. Moreover, the scale regions of the test strip define a grey scale permutation that uniquely corresponds to a calibration code of the test strip. The grey scale photodetector module is configured to detect the permutative grey scale calibration pattern of the test strip when the test strip is inserted into the meter.Type: GrantFiled: May 26, 2006Date of Patent: September 15, 2009Assignee: Lifescan Scotland LimitedInventors: Grenville Arthur Robinson, John McInulty, Damian Edward Haydon Baskeyfield, Thomas J.

Publication number: 20090027040Abstract: System, circuits, and methods to reduce or eliminate uncompensated voltage drop between an electrode of an electrochemical cell usable for analyte measurement. In one example, a system is provided that includes a test strip, a reference voltage circuit, an operational amplifier connected to the reference voltage circuit to provide a predetermined fraction of a reference voltage substantially equal to the test voltage applied to the first line, the operational amplifier having an output configured for one of a connected or disconnected state to the first line, and a processing circuit connected to the output of the operational amplifier and the first line such that, during a disconnected state between the output and the first line, the processing circuit remains in connection with the first line.Type: ApplicationFiled: July 25, 2007Publication date: January 29, 2009Applicant: LifeScan, Inc.Inventors: Mahyar Z.

Patent number: 7474391Abstract: A method for determining a test strip calibration code for use in a meter includes inserting a calibration strip into the meter, with the calibration strip having a substrate and a permutative grey scale calibration pattern disposed on the substrate. In addition, the permutative grey scale calibration pattern includes more than one grey scale region that define a grey scale permutation uniquely corresponding to a calibration code of test strips in a package associated with the calibration strip. The method also includes: (i) detecting the permutative grey scale calibration pattern with a grey scale photodetector module of the meter, and (ii) determining a calibration code that uniquely corresponds to a grey scale permutation defined by the permutative grey scale calibration pattern based on a permutation matrix stored in the meter.Type: GrantFiled: May 26, 2006Date of Patent: January 6, 2009Assignee: Lifescan Scotland LimitedInventors: Damian Edward Haydon Baskeyfield, Thomas J.
