A capacitive sensor including an electrically conductive material, and a single electrode applied with positive potential, wherein the distance between the single electrode and the electrically conductive material determines the spherical radius for a proximity sensing range.

Method and device for controlling the quantity of liquid contained in a cartridge for an aerosol generating device, wherein the cartridge has a container and a liquid contained in the container and wherein, according to which is measured the quantity of liquid contained in the cartridge; and compared the quantity of liquid with a reference quantity of liquid.

One embodiment provides a method for detecting aspiration in a clinical analyzer, including: acquiring, from a sensor, pressure measurement data; transforming the pressure measurement data into frequency domain data; generating a clean version of the frequency domain data by attenuating, using a filter, unwanted frequencies; comparing the cleaned version of the frequency domain data to one or more predetermined data points; and determining, based on the comparison, if an aspiration was properly performed. Other aspects are described and claimed herein.

An autonomous spacecraft propellant-gauging system, the system including a propellant tank, one or more heating devices, at least one temperature sensor and a processor. The heating devices are used to heat up the propellant tank, and the temperature sensors sense the temperature of the propellant content of the propellant tank. The processor controls operations of the heating devices and the temperature sensor. The processor further executes an algorithm to automate gauging of the propellant content of the propellant tank based on a reduced order model (ROM) and a number of parameters, and reports out an estimate of the mass of the remaining propellant of the propellant tank.

A volume measurement system for a fluid processing device includes a fluid container, an imaging unit, and a controller. The container includes a housing defining the structure of the fluid container, and a plurality of fluid chambers. The fluid chambers collect and/or store fluid from the fluid processing device, and each have a port that allows fluid to enter and/or exit the fluid chambers. The imaging unit takes images of the fluid chambers and is positioned to view a level of fluid in each of the chambers. The controller is in communication with the imaging unit and determines the volume of fluid within each of the fluid chambers based upon the viewed level of fluid in the fluid chambers.

A toilet for measuring excreta is disclosed. The toilet is adapted to measure the amount of excreta received by the bowl and then the flush water. A pressure sensor is configured to monitor the pressure exerted by the flush water and any excreta contained therein. Data from monitoring the pressure of the flush water and excreta therein is used to determine the weight or volume of the excreta received by the bowl. This toilet can provide data which may be used to analyze how the volume of flush water changed due to excreta deposit. A volume change feature can be associated with a urination event and the data associated with the event can be used to determine a urine characteristic of the event.
