An indirectly heated capillary aerosol generator comprises a capillary tube adapted to form an aerosol when liquid material in the capillary tube is heated to volatilize at least some of the liquid material therein and a thermally conductive material in thermal contact with the capillary tube. The indirectly heated capillary aerosol generator provides substantially even and uniform heating across the heated length of the capillary tube.

A method of manufacturing an orifice is provided to make the orifice capable of spraying a very small amount of fluid in an ultra-high pressure and very low temperature environments. The method also makes it possible to provide the orifice with reduced volume and mass. More specifically, the method effectively realizes a desired hydraulic performance through a simple manufacturing method in which a part of a capillary pipe is pressed to form a channel region having a cross section close to a rectangular shape.

A wireless charging air compressor includes a housing having a motor operably connected to an air pump, which forces air into a cavity, and an actuator operably connected to the cavity for selectively discharging air through a nozzle secured to the housing. A rechargeable battery is operably connected to the motor for providing power to the motor. A wireless charging receiver mechanism is operably connected to the rechargeable battery. The wireless charging receiver mechanism is configured to recharge the rechargeable battery upon interacting with a wireless charging transmission mechanism. This allow the rechargeable battery to be recharged without the need for a hardwired connection.

In one arrangement, a vibration system includes a vibratable plate, a support member surrounding the vibratable plate, and a vibration-inducing member surrounding the support member. The vibration-inducing member is configured to radially expand and contract against the support member so as to produce axial vibration of the vibratable plate. In another arrangement, the vibratable plate has an outer circumference; a tubular member is concentrically disposed about the outer circumference of the plate, and an annular vibration-inducing member is concentrically disposed about the outer circumference of the tubular member. The vibration-inducing member is preferably a piezoelectric ring that is radially expandable and contractable against the wall of the tubular member to cause the plate to vibrate in the axial direction.

Devices, systems, and methods are directed to applying magnetohydrodynamic forces to liquid metal to eject liquid metal along a controlled pattern, such as a controlled three-dimensional pattern as part of additive manufacturing of an object. Electric current delivered to a meniscus of the liquid metal in a quiescent state can be directed to exert a pullback force on the liquid metal. The pullback force can be sufficient to draw the liquid metal, in the quiescent state, in a direction toward the nozzle to reduce the likelihood of unintended wetting of surfaces of the nozzle between uses of the nozzle.

Aspects of the invention include a device for fluid delivery to the ocular surface having a self-alignment system. The fluid delivery device includes a fluid package having a reservoir and one or more apertures, an actuator component configured to eject fluid from the reservoir through the one or more apertures and an image-based self-alignment system configured to align fluid ejected through the one or more apertures with a target location on the eye of a user. Also provided are methods of using the devices in fluid delivery applications, as well as a kit that includes components of the devices.

A liquid atomizing system electrically charged in a wireless manner: a liquid, a wireless charger, and an atomizer including a wireless charging receiver. The liquid is filled in the atomizer, and the wireless charger is electrically connected with a power source so that an electric power is inputted to the wireless charger from the power source to produce a magnetic field and to send an electromagnetic signal, thus transmitting energy by using the magnetic field. The wireless charging receiver of the atomizer is close to the electromagnetic signal sent by the wireless charger so as to receive the electromagnetic signal and to convert the electromagnetic signal into the electric power for driving the atomizer to atomize the liquid to micro water molecule and to deliver the micro water molecule to an external environment.
