Abstract: A mask for a patient and a method for reducing exposure of aerosol particles emitted from the patient to other individuals. The mask may have an inner chamber configured to enclose a nose and a mouth of the patient. The mask may further have a negative pressure chamber fluidly connected to the inner chamber. The negative pressure chamber may have an outer opening and a suction opening. The outer opening may be covered by a seal. The seal may be configured to be cut or opened to form a device opening providing access to the nose of the patient. The device opening may receive a medical device and form a seal around the medical device. The suction opening may be configured to couple to a suction device for removing the aerosol particles located within the inner chamber and the negative pressure chamber.

Abstract: Systems and methods for improved fluid dispensing process control using a machine learning tool are disclosed. In an example method, successive portions of viscous fluid are dispensed by a dispensing device according to operating parameters to train a machine learning tool to associate defect classifications with images of dispensed portions and/or operating parameters associated with dispensing the dispensed portions. The trained machine learning tool is then used in a closed loop fashion in production to detect and correct for defects associated with the dispensed portions to improve quality and production efficiency.

Abstract: A differential emissivity imaging device (200) for measuring evaporable particle properties can include a heated plate (204), a thermal camera (206), a memory device (208), and an output interface. The heated plate (204) can have an upper surface (212) oriented to receive falling evaporable particles (202). The evaporable particles (202) have a particle emissivity and the upper surface (212) has a plate surface emissivity. The thermal camera (206) can be oriented to produce a thermal image of the upper surface (212). The memory device (208) can include instructions that cause the imaging device (200) to calculate a mass of the individual evaporable particle (202) via heat conduction using a calculated surface area and an evaporation time.
