  • Publication number: 20160256070
    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: 20150143356
    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.

  • Patent number: 8649997
    Abstract: A system for a meter configured to determine an analyte concentration of a fluid sample includes a housing and a temperature sensor disposed within the housing. The system also includes a processor configured to receive temperature data from the temperature sensor upon the meter entering one of a charge state and a discharge state. The processor is further configured to predict a temperature value that approximates the ambient temperature outside of the housing. The predicted temperature value is based on historical temperature data received from the temperature sensor such that the predicted temperature value remains constant if a recently received temperature value remains within predetermined upper and lower temperature thresholds and the recently received temperature value exceeds the at least one predicted temperature value.
