  • 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: 10398343
    Abstract: A moisture sensor includes a pair of electrode plates separated by a moisture absorbent material that forms the dielectric of a capacitive sensor. As the absorbent dielectric material absorbs moisture, such as perspiration, the capacitance of the sensor changes reflecting a quantitative measure of perspiration absorbed. The sensor can be stabilized by capacitively coupling the dielectric material to the skin of the user to improve sensor stability and noise rejection. The sensor can include a capacitive sensing integrated circuit that measures the capacitance of the sensor in close proximity to the electrodes to limit the introduction of noise.

  • Publication number: 20190145837
    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: 10277386
    Abstract: An on-body sensor system includes a hub configured to be attached to a surface of a user. The hub being further configured to transmit electrical power and/or data signals into the surface and to receive response data signals from the surface. The system further including at least one sensor node configured to be attached to the surface. The sensor node being further configured to receive the electrical power and data signals from the hub through the surface and to transmit the response data signals into the surface. The electrical power from the hub can power the sensor node and cause or enable the at least one sensor node to generate sensor information that is transmitted back to the hub within the response data signals.

  • Publication number: 20190103176
    Abstract: 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.
