  • Patent number: 10989611
    Abstract: 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.

  • Patent number: 10753923
    Abstract: A test meter for analyzing a body fluid sample applied to a test strip includes an outer housing having an opening, an actuator, and a cartridge positioned adjacent the outer housing. The cartridge further includes a dispensing member connected to the actuator, a plurality of stacked test strips biased toward the dispensing member, and a cartridge outer housing that is adjacent at least a portion of the dispensing member. Each time the actuator is actuated, the dispensing member is rotated to cause movement of one test strip from the plurality of stacked test strips through the opening, and another test strip is biased toward the dispensing member.

  • Patent number: 9547005
    Abstract: A test meter system for testing a characteristic of a fluid, the test meter system including a test meter having a housing with an opening adapted to accept a test strip, an interrogation coil within the housing, a pick-up coil within the housing, and a test strip including at least one magneto-elastic-resonance sensor. When the test strip is within the opening, the interrogation coil may utilize magneto-elastic-resonance technology to interrogate the magneto-elastic-resonance sensor and the pick-up coil may be used to sense a resultant oscillation frequency of the magneto-elastic-resonance sensor, the resultant oscillation frequency associated with the characteristic. The test strip may include a plurality of sensors. The sensors may be coated with a coating sensitive to a characteristic of the fluid, where the interrogation reveals information about the fluid characteristic.
