Abstract: An ejector device for ejecting droplets of fluid onto a surface includes an ejector mechanism attached to a fluid reservoir through a fluid loading plate that is configured to pierce the reservoir and channel the fluid to a rear surface of the ejector mechanism by capillary action. The ejector mechanism may have a centro-symmetric configuration with a lead free piezo actuator and may be covered by an auto-closing cover.

Abstract: The present disclosure relates to ejector mechanisms and devices for generating a directed stream of droplets, as well as improved methods for delivering an ejected stream of droplets to a target. The device and methods may be useful for the delivery of fluid for ophthalmic, topical, oral, nasal, or pulmonary use, more particularly, for use in the delivery of ophthalmic fluid to the eye. Certain aspects of the disclosure relate to devices and methods for the delivery of a therapeutically effective low dosage volume medicament composition to a target, e.g., by controlling charge, droplet size and/or droplet deposit parameters of the medicament composition.

Abstract: A method of delivering safe, suitable, and repeatable dosages to a subject for topical, oral, nasal, or pulmonary use and a device for droplet ejection includes a fluid delivery system capable of delivering a defined volume of the fluid in the form of droplets having properties that afford adequate and repeatable high percentage deposition upon application. The method and device include a housing, a reservoir disposed within the housing for receiving a volume of fluid, an ejector mechanism configured to eject a stream of droplets having an average ejected droplet diameter greater than 15 microns, the stream of droplets having low entrained airflow such that the stream of droplets deposit on the eye of the subject during use.

Abstract: Implementations described and claimed herein provide air filtration monitoring. In one implementation, air filtration data is received from one or more air filtration systems over a network. Each of the one or more air filtration systems is configured to provide purified air into an enclosed space by removing ultra-fine particles from air using at least one primary filter. The air filtration data is captured by one or more sensors. The air filtration data is correlated based on at least one monitoring parameter, and air filtration analytics are generated from the correlated data. In another implementation, health data is received from a controller in an air filtration system. The health data is captured using one or more sensors. Health monitoring analytics are generated from the health data, and feedback is generated from the health monitoring analytics.

Abstract: Implementations described and claimed herein provide systems and methods systems and methods for removing ultra-fine particles from air. In one implementation, a low power air purifying respirator is configured for filtering ultra-fine particles using a primary filter having a composite filter media, which may be pleated and may provide no outgassing. The respirator includes at least one fan providing positive pressure air flow to the primary filter at a low face velocity. The at least one fan may comprise a plurality of serially stacked, axial fans configured to increase air pressure without increasing flow. One or more safety valves are disposed along the air flow path to prevent back flow and carbon dioxide buildup during use. A user device may be in communication with a controller in the respirator to control the operations of the respirator. The respirator may be connected to a mask via a hose.
