A capacitive sensing system may include a fluid cup configured to receive a fluid, and processing circuitry and a capacitive sensor coupled to one another, the capacitive sensor is a distance separated from and in parallel with a top surface of the fluid in the fluid cup, the distance the capacitive sensor is separated from the top surface of the fluid being variable with a fill level of the fluid in the fluid cup. The capacitive sensor and the fluid in the fluid cup may form elements of a capacitor with a capacitance that is a function of at least the distance the capacitive sensor is separated from the top surface of the fluid. The processing circuitry may be configured to measure a change in signal corresponding to a change in capacitance of the capacitor and determine the fill level based on a magnitude of the change in signal.

Capacitive sensing system and related method

A solid-production system for producing a solid on demand is provided herein. In some aspects, the solid-production system includes a conveying mechanism; a fluid-dispensing mechanism; a pressure plate arranged to urge the fluid mold into interaction with a cooling block to form a solid; a solid-dispensing mechanism arranged to dispense the solid loosened by a solid ejector to a user; and processing circuitry configured to implement a master state machine, and slave state machines for respective ones of the fluid-dispensing mechanism, conveying mechanism, pressure plate and solid-dispensing mechanism, wherein the master state machine is configured to send commands to the slave state machines based on states of the slave state machines, and the slave state machines are configured to execute the commands to control the respective ones of the conveying mechanism, fluid-dispensing mechanism, pressure plate, and solid-dispensing mechanism.
