Abstract: A system includes: a water reservoir configured to store water; a brew chamber extending below and contiguous with the water reservoir; a piston configured to run in the brew chamber, defining a base of the water reservoir, defining a port extending between the water reservoir and the brew chamber, and including a valve coupled to the fill port and operable in a) a closed position during downward advancement of the piston and b) an open position during upward retraction of the piston; a heating element configured to heat water occupying the brew assembly; and an actuator configured to retract the piston to transfer water from the water reservoir, through piston via the port, and into the brew chamber and to advance the piston by a target piston travel distance—corresponding to a piston swept volume that yields a target brew volume—to displace liquid from the brew chamber.

Abstract: A system for evaluating breast cancer risk in a user includes: a temperature-sensing brassiere including: a first sensor mesh comprising: a first flexible mesh defining a mesh pattern and extending across a first breast region of the user; a first set of temperature-sensing assemblies arranged at intersections in the first flexible mesh; and for each temperature-sensing assembly in the first set of temperature-sensing assemblies, an electrical trace in the first mesh electrically coupling the temperature-sensing assembly to a controller; a brassiere structure configured to locate the first sensor mesh across the first breast region of the user; and the controller configured to: sample each temperature-sensing assembly in the first set of temperature-sensing assemblies during a data collection period to generate a series of temperature data; and store the series of temperature data.
