Abstract: A powering subassembly (1000) for a portable electronic device includes a main battery (1010), a converter (1060), a backup battery (1070), and a controller (1075). The main battery (1010) provides a main voltage and the backup battery (1070) can provide a backup voltage. The converter (1060) receives the main voltage and increases the main voltage to at least one operating voltage. The controller (1075) receives the operating voltage from the converter (1060), monitors the voltage of the main battery (1010), and compares the monitored main battery voltage to a main battery low voltage threshold. The controller (1075) transmits a disconnect signal to decouple the main battery (1010) from the converter (1060) if the monitored voltage from the main battery (1010) is less than the main battery low voltage threshold. The controller (1075) transmits a connection signal to couple the backup battery (1070) to the converter (1060) if the monitored voltage is less than the main battery low voltage threshold. The backup battery (1070) provides the power for a predetermined minimum amount of time.

Abstract: A medical device includes a hub and an adhesive patch coupled to the hub. The adhesive patch is to couple the hub to an anatomy. The adhesive patch defines an edge that extends along a perimeter of the adhesive patch. The medical device includes an anisotropic shim coupled to the adhesive patch along the perimeter of the adhesive patch proximate the edge to resist an uncoupling of the adhesive patch from the anatomy. The shim has an inner periphery spaced apart from an outer periphery and the shim is locally rigid between the inner periphery and the outer periphery.

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. Correction actors, fusion algorithms, EIS, and advanced ASICs may be used to implement the foregoing, thereby achieving the goal of improved accuracy and reliability without the need for blood-glucose calibration, and providing a calibration-free, or near calibration-free, sensor.
