  • Patent number: 12011293
    Abstract: A sensor assembly for sensing a physiological characteristic includes a power source, a power control switch, and a power latch configured to latch an output of the power control switch. The sensor assembly also includes a power converter coupled to the power control switch. The power converter is configured to step down a voltage of the latched output of the power control switch for delivery of the latched output to one or more components of the sensor assembly. The power control switch is configured to inhibit consumption of power from the power source when the sensor assembly is in a pre-deployment state and output the latched output to the power converter in response to transition of the sensor assembly from the pre-deployment state to a deployed state.

  • Patent number: 11992656
    Abstract: A method of operating an insulin infusion device involves: operating the infusion device in an automatic mode to automatically control delivery of insulin to a user, in accordance with a first target glucose setpoint value; receiving user status data that indicates sleeping status of the user, the user status data generated by a sleep detection system; and determining, from the user status data, that the user is sleeping while the insulin infusion device is operating in the automatic mode. In response to the determining, the method transitions from the first target glucose setpoint value to a second (different) target glucose setpoint value for use during the automatic mode, the transitioning occurring without user input. The method continues to operate the infusion device in the automatic mode to automatically control delivery of insulin to the user, in accordance with the second target glucose setpoint value.

  • Patent number: 11986633
    Abstract: Techniques related to temporary setpoint values are disclosed. The techniques may involve causing operation of a fluid delivery device in a closed-loop mode for automatically delivering fluid based on a difference between a first setpoint value and an analyte concentration value during operation of the fluid delivery device in the closed-loop mode. Additionally, the techniques may involve obtaining a second setpoint value. The second setpoint value may be a temporary setpoint value to be used for a period of time to regulate fluid delivery, and the second setpoint value may be greater than the first setpoint value. The techniques may further involve causing operation of the fluid delivery device for automatically reducing fluid delivery for the period of time based on the second setpoint value.

  • Patent number: 11963768
    Abstract: A continuous glucose monitoring system may utilize externally sourced information regarding the physiological state and ambient environment of its user for externally calibrating sensor glucose measurements. Externally sourced factory calibration information may be utilized, where the information is generated by comparing metrics obtained from the data used to generate the sensor's glucose sensing algorithm to similar data obtained from each batch of sensors to be used with the algorithm in the future. The output sensor glucose value of a glucose sensor may also be estimated by analytically optimizing input sensor signals to accurately correct for changes in sensitivity, run-in time, glucose current dips, and other variable sensor wear effects.
