Abstract: The present disclosure relates to a device configured to move within a body cavity, such as the gastrointestinal tract, in particular, the small intestine, and methods of using the device. The presently disclosed device may be self-driving, e.g., through the use of one or more traction-motion element, and the articulation of a tip of the device may be controlled and fine tuned. The presently disclosed device may be used in a variety of body cavities such as a vascular body lumen, a digestive body lumen, a respiratory body lumen, or a urinary body lumen, for example, for endoscopic purposes, for delivering a substance into the body cavity, for removing a substance or tissue from the body cavity, for capturing an image of the body cavity, and/or for performing an operation of a tissue or organ using the device.

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: 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.
