Publication number: 20100309947Abstract: Methods and systems accurately determine an analyte concentration in a fluid sample. In an example embodiment, a receiving port receives a test sensor. The test sensor includes a fluid-receiving area for receiving a fluid sample. The fluid-receiving area contains a reagent that produces a measurable reaction with an analyte in the fluid sample. The test sensor has a test-sensor temperature and the reagent has a reagent temperature. A measurement system measures the reaction between the reagent and the analyte. A temperature-measuring system measures the test sensor temperature when the test sensor is received into the receiving port. A concentration of the analyte in the fluid sample is determined according to the measurement of the reaction and the measurement of the test sensor temperature. A diagnostic system determines an accuracy of the temperature-measuring system. The calculation of the analyte concentration may be adjusted according to the accuracy of temperature-measuring system.Type: ApplicationFiled: June 8, 2010Publication date: December 9, 2010Applicant: BAYER HEALTHCARE LLCInventors: Narasinha Parasnis, Hoi-Cheong Steve Sun, Wu Mu

Publication number: 20080301158Abstract: A portable data-management system may be easily employed with multiple processing devices by eliminating the need to pre-install additional programs, agents, device drivers, or other software components on the hosts. A portable storage device contains software for a data-management application, which receives and processes test data from a meter that measures an analyte. The portable device may employ an interface protocol that makes the portable device immediately compatible with different operating systems and hardware configurations. Once the portable device is connected to the host, the data-management application can be automatically launched. The convenience and portability of a data-management system may be enhanced by integrating advanced data processing and display features with the portable device. The users may access some advanced presentations of health data without having to launch the data-management application on a separate host.Type: ApplicationFiled: May 29, 2008Publication date: December 4, 2008Inventors: Darren Brown, Jun Chen, Igor Gofman, Steven B.

Publication number: 20080301665Abstract: An architecture allows individual system components to be developed and tested individually, i.e., as distinct modules, and to be subsequently combined through standardized electrical and communication interfaces. Any combination of these modules can be implemented to form different products that provide any number of functions, such as an integrated system for monitoring a health condition and/or delivering a medication. The architecture also provides an approach for dynamically updating the product and offering its users the latest generation of technology even after the users have already purchased the product. In particular, the embodiments employ the communication interfaces to also provide connection to a remote network that can update or upgrade the product's software when the product is out in the field.Type: ApplicationFiled: May 29, 2008Publication date: December 4, 2008Inventors: Steven Charlton, Jun Chen, Lin Chen, Qiang Fu, Igor Gofman, Steven B.
