  • Patent number: 10481013
    Abstract: A system and method for rapidly determining ambient temperature in a fluid-analyte meter. The meter includes a housing defining an interior space and an area for receiving a fluid sample. A processor and a first temperature sensor are disposed within the interior space of said the housing. A second temperature sensor is disposed on the housing. One or more processors are configured to determine a first temperature value from temperature data received from the first temperature sensor. The processor(s) are also configured to apply a variable current to a temperature-adjustment source such that the second temperature sensor is adjusted to a predetermined steady-state temperature value different from the first temperature value. The processor(s) are further configured to determine an ambient temperature of an exterior space of the housing based on the applied variable current, pre-determined steady-state temperature, and received first temperature values.

  • Patent number: 10478103
    Abstract: Embodiments of the invention provide apparatus, systems, and methods wherein pre-event and post-event analyte concentration readings associated with an event are collected and processed to determine a numerical delta. The numerical delta may be displayed on a visual display to aid in a ready determination of the affect that the event (alone or in combination with medication and/or insulin dosages) had on the analyte concentration levels. Medication and/or insulin dosages may be displayed alongside the numerical delta to gauge immediate relationships between numerical delta, dosage, and/or an associated event. Apparatus and systems for calculating and displaying the numerical delta are described, as are other aspects.

  • Patent number: 10468127
    Abstract: 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.

  • Patent number: 10444178
    Abstract: A sensor system including devices and methods for determining the concentration of an analyte in a sample is described. Input signals including amperometric and voltammetric duty cycles of excitations and relaxations may provide a shorter analysis time and/or improve the accuracy and/or precision of the analysis. The disclosed system may reduce analysis errors, thus improving measurement performance, by adjusting the potential and/or scan rate in response to output currents obtained from voltammetric scans. The disclosed system also may determine the concentration of more than one ionizable species in the sample by adjusting the potential and/or scan rate in response to output currents obtained from voltammetric scans. The multiple, determined concentrations may be used to determine the concentration of multiple analytes or to correct the concentration determined for an analyte, thus improving the measurement performance of the system.

  • Patent number: 10416110
    Abstract: The present invention relates to systems, methods, and devices for determining the concentration of an analyte in a sample. The use of linear, cyclic, or acyclic voltammetric scans and/or semi-integral, derivative, or semi-derivative data treatment may provide for increased accuracy when determining the concentration of an analyte in a sample. Hematocrit compensation in combination with the data treatments may reduce the hematocrit effect with regard to a glucose analysis in whole blood. In another aspect, fast scan rates may reduce the hematocrit effect.

  • Patent number: 10345255
    Abstract: A sensor system, device, and methods for determining the concentration of an analyte in a sample is described. Input signals including multiple duty cycles of sequential excitation pulses and relaxations are input to the sample. One or more signals output from the sample within 300 ms of the input of an excitation pulse may be correlated with the analyte concentration of the sample to improve the accuracy and/or precision of the analysis. Determining the analyte concentration of the sample from these rapidly measured output values may reduce analysis errors arising from the hematocrit effect, mediator background, and other error sources.

  • Patent number: 10330629
    Abstract: During analyte analysis, errors may be introduced into an analysis by both the biosensor system used to perform the analysis and by errors in the output signal measured by the measurement device of the biosensor. For a reference sample, system error may be determined through the determination of relative error. However, during an analysis of a test sample with the measurement device of the biosensor system, true relative error cannot be known. A pseudo-reference concentration determined during the analysis may be used as a substitute for true relative error. The present invention introduces the determination of a pseudo-reference concentration determined during the analysis as a substitute for the true relative error and uses an anchor parameter to compensate for the system error in the analysis-determined pseudo-reference concentration.

  • Patent number: 10330666
    Abstract: A test sensor (100) for determining an analyte concentration in a biological fluid comprises a strip including a fluid receiving area (128) and a port-insertion region (126). A first row of optically transparent (132) and non-transparent positions forms a calibration code pattern (130) disposed within a first area of the port-insertion region (126). A second row of optically transparent (142) and non-transparent positions forms a synchronization code pattern (140) disposed within a second area of the port-insertion region (126). The second area is different from the first area. The synchronization code pattern (140) corresponds to the calibration code pattern (130) such that the synchronization code pattern (140) provides synchronization of the serial calibration code pattern (130) during insertion of the port-insertion region (126) into the receiving port of the analyte meter.

  • Patent number: 10320212
    Abstract: A system and method is described for rapid charging and power management of a battery for a meter. A charger component is operably associated with the meter and is capable of executing a rapid charge algorithm for a rechargeable battery. The algorithm includes monitoring for a connection to an external power source and implementing a charging routine of a battery at a first charge rate and then at a second charge rate. The second charge rate is lower than the first charge rate. A temperature rise in the rechargeable battery due to the first charge rate has a negligible heat transfer effect on the fluid sample. The meter can also include a power switch for controlling current flow to a battery fuel gauge. The power switch is open when the meter enters into a sleep mode. The state of battery charge is determined after the meter exits the sleep mode.

  • Patent number: 10267679
    Abstract: A testing system configured to determine an analyte concentration has a user interface that includes a number of visual indicators on its exterior housing. The visual indicators convey different types of information to a user of the testing system when illuminated. Additionally, the indicators are independent of one another in that they can each be illuminated in different colors from one other and turn on and/or off independently of one another. Further, the visual indicators are illuminated using a common lighting element (e.g., a single light emitting diode (“LED”)) in combination with one or more waveguides and one or more filters located inside the testing system.
