Abstract: Apparatus and associated methods disclosed herein relate to configuring a light emitter to direct emitted light having a preselected wavelength through a liquid retained by a collapsible reservoir to a light sensor disposed in the collapsible reservoir, determining a distance separating the light emitter from the light sensor across the collapsible reservoir interior based on the amount of emitted light absorbed by the liquid, and determining the volume of the liquid retained by the collapsible reservoir based on the distance. The liquid may comprise an active compound formulation. An excipient may be added to the liquid in an excipient concentration governing a linear relationship between distance and light absorption at the preselected wavelength. The distance may be determined as a function of the linear relationship. The risks of abrupt therapy cessation or premature refill may be advantageously reduced by providing real-time remaining liquid volume measurements as the collapsible reservoir collapses.

Abstract: A flood footprint estimation system that can generate a requested flood footprint is described herein. For example, the flood footprint estimation system can estimate water surface elevations at various points along a stream or river. The flood footprint estimation system can then perform a smoothing operation on the estimated water surface elevations to generate a trend line or curve of the estimated water surface elevations in which each point of the trend line or curve corresponds to a water surface elevation value that is no greater than any of the water surface elevation values of the previous points of the trend line or curve. The flood footprint estimation system can use the trend line or curve to perform an iterative water expansion to determine which geographic locations may flood. Results of the iterative water expansion can be provided to a user device in the form of a user interface.
