The respiration sensor includes a capacitive electrode assembly that has a varying capacitance correlated to a respiratory airflow from a user, a resonant circuit that generates a resonant signal based on the varying capacitance, a signal analyzing circuit that obtains a detected vital capacity value and a period time data piece related to a breathing cycle of the user based on a frequency variation of the resonant signal, and an atomization adjustment module that generates a cumulative effective inhaled dose value based on the detected vital capacity value and the period time data piece. The atomization adjustment module causes the medication atomizer to stop generation of an aerosol airflow when the cumulative effective inhaled dose value exceeds a predetermined dose threshold value.

Abstract: Examples of syringe assemblies and sets of components are disclosed for transferring a fluid sample for testing. In some examples, the syringe assembly comprises a housing, a barrel, a plunger reciprocally moveable in the barrel, a narrow tube connected to the barrel, and a metering actuator configured to control movement of the plunger at least in a proximal direction relative to the barrel.

Abstract: A microwave heat treatment method for granulated blast furnace slag is provided, which includes the following steps: subjecting the granulated blast furnace slag to microwave heat treatment at a frequency of 900-930 MHz and then cooling the slag. Microwave rapid heating is utilized to remove the moisture in the granulated blast furnace slag, stress is generated inside the granulated blast furnace slag particles to promote the formation of cracks or the decomposition of the granulated slag particles into small particles. After the microwave reaches a certain power, the microwave is turned off, an air blower is turned on, and thermal stress is generated inside the granulated blast furnace slag particles, so that the particles are further promoted to generate cracks or fragmentation; and then the desired fine powder can be obtained by ball milling the granulated blast furnace slag after microwave heat treatment for a short time.
