  • Publication number: 20190357814
    Abstract: The double layer capacitance of a working electrode of a sensor may be measured with minimal disruption to the sensor equilibrium by open circuiting the working electrode and measuring the voltage drift on a periodic, or as-needed, basis. The values of the double layer capacitance may be monitored over time to determine, e.g., sensor age and condition.

  • Publication number: 20190357816
    Abstract: A blood glucose sensing system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes stabilization circuitry. The stabilization circuitry causes a first voltage to be applied to one of the electrodes for a first timeframe and causes a second voltage to be applied to one of the electrodes for a second timeframe. The stabilization circuitry repeats the application of the first voltage and the second voltage to continue the anodic—cathodic cycle. The sensor electronics device may include a power supply, a regulator, and a voltage application device, where the voltage application device receives a regulated voltage from the regulator, applies a first voltage to an electrode for the first timeframe, and applies a second voltage to an electrode for the second timeframe.

  • Patent number: 10387337
    Abstract: An apparatus includes a communication interface, a controller, and a power section. The communication interface is configured to receive power from an external host to the apparatus. The controller is configured to limit a current drawn by the communication interface to a predetermined value when the apparatus is powered through the external host. The power section is configured to generate a first voltage from a portion of the limited current drawn by the communication interface. The first voltage powers a data storage circuitry. The power section is further configured to store electrical charges received from another portion of the limited current drawn by the communication interface. The power section is further configured to generate a second voltage from the stored electrical charges in response to a signal from the controller. The second voltage supplements the first voltage during high power events by the data storage circuitry.

  • Patent number: 10288578
    Abstract: A sensor system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes a connection detection device, a power source, and a delay circuit. The connection detection device determines if the sensor electronics device is connected to the sensor and transmits a connection signal. The delay circuit receives the connection signal, waits a preset hydration time, and couples the regulated voltage from the power source to an electrode in the sensor after the preset hydration time has elapsed. Alternatively, the sensor electronics device may include an electrical detection circuit and a microcontroller. The electrical detection circuit determines if the plurality of electrodes are hydrated and generates an interrupt if the electrodes are hydrated. A microcontroller receives the interrupt and transmits a signal representative of a voltage to an electrode of the plurality of electrodes.
