A floating humidifier using a vertical power transmission scheme according to an embodiment of the present disclosure includes: a wireless power transmitting unit including a substrate and a vertical structure vertically arranged on the substrate, and configured to transmit electric power in a magnetic induction scheme through the substrate and the vertical structure; a water container including an accommodation portion in which water is accommodated and a fastening portion protruding from a center of the accommodation portion and fitted in the vertical structure above the wireless power transmitting unit; and a humidification generating unit inserted into the fastening portion of the water container through a vertically penetrated fastening hole and configured to generate a current using a magnetic force induced by the wireless power transmitting unit to drive a humidifier.

A fluidized bed coating apparatus for coating liquid onto the surfaces of particles directed into a coating chamber. A liquid spray nozzle assembly disposed below a hollow separator within the coating chamber includes an ultrasonic atomizer for atomizing coating liquid into a fine liquid particle cloud and a pressurized air directing air cap for forming the ultrasonically atomized fine liquid particle cloud into a cone shaped spray pattern and propelling the liquid particles through the separator into an upbed region of the coating chamber for recirculation in an outbed region, and through the separator. A cooling air passageway system is provided within the spray nozzle assembly for cooing the ultrasonic atomizer during operation.

A feeding mold is provided with a charging runner for coating, a feeding runner connected to the charging runner, and a mold base adjacent to the feeding runner. The feeding runner is provided with a splitting manifold communicated with the charging runner, a discharging end face located at the end of feeding runner and apart from an atomizing knife edge of ultrasonic oscillating element by a gap, and a slit channel connected to the splitting manifold and discharging end face. The mold base is connected at a side edge thereof to the bottom of discharging end face, and inclined at a first angle toward the discharging end face. The side edge is located at the lowest position. Accordingly, the backflow of coating on the discharging end face to the mold base from the side edge and formation of trickle are impossible, so as to use coating adequately and avoid pollution.

A sprayer that senses the presence or character of a surface to be sprayed includes one or more sensors configured to detect a presence or character of a surface to be sprayed; and a dispenser assembly including one or more components configured to modify at least one spray characteristic of a formulation based on an input from at least one of the one or more sensors indicative of the presence or character of the surface to be sprayed.

A method and apparatus for applying a bone attachment coating to a prosthetic component, the bone attachment coating being formed from a plurality of particles applied to a surface of the prosthetic component. The method comprising: locally exciting the particles so as to increase the kinetic and/or thermal energy of the particles; and applying pressure to the particles by virtue of a press arranged so as to press the particles against the surface of the prosthetic component at an interface between the press and the prosthetic component. The kinetic and/or thermal energy of the particles causes localised heating of the component such that the particles may be embedded into the surface of the prosthetic component.

An assembly includes: a first component; a second component enclosed by the first component; a diaphragm that covers a radial gap between the first and second components and is fixed in each case in a sealed manner; and a volume of a medium that is enclosed by the first and second components and the diaphragm. For the purpose of achieving a simple filling process of the assembly with the medium at a reliable sealing of the enclosed volume, even in the case of high, swelling pressures acting upon the assembly, in one of the components a filling valve is situated that opens towards the volume, which filling valve is situated as a check valve having spring resetting in a filling channel running in the component.

A secondary ultrasonic nebulisation device is disclosed comprising: a liquid sample delivery capillary; a sample receiving surface arranged for receiving a liquid sample from the capillary; and an ultrasonic transducer configured for oscillating the surface so as to nebulise the liquid sample received thereon, wherein the device is configured such that the oscillations of the surface by the ultrasonic transducer cause charged droplets and/or gas phase ions to be generated from the sample.

A washer nozzle for a vehicle is provided. The washer nozzle improves an ejection disorder due to external freezing of a washer ejection port that ejects washer fluid. The washer nozzle, removes ice and foreign substances frozen onto the surface of a washer ejection port by utilizing an ultrasonic vibration generated by an ultrasonic transducer disposed within an interior of the washer nozzle. The washer nozzle includes a nozzle cover with washer ejection ports and a nozzle body with washer fluid passages. The ultrasonic transducer is configured to generate an ultrasonic vibration disposed within the nozzle body. The ultrasonic transducer disposed beneath the lower portion of the washer ejection ports is configured to provide ultrasonic vibration toward the washer ejection ports.

Disclosed is an ultrasonic spray coating system wherein (1) the surface of the feed blade of the ultrasonic spray head has been modified to add a series shallow channels to redirect the ultrasonic surface wave system that exists on the surface; (2) the internal passageway of the liquid applicator has been modified to add a series of channels to uniformly feed the liquid from the liquid applicator to the spray-forming tip; (3) a positive displacement pump is utilized to deliver the liquid to the spray head at a precise flow rate independent of the associated resistances of the liquid delivery system components; and (4) the output orifice of the primary gas director is extended to impinge the directed gas stream at a position closer to the spray-forming tip.

A unit dose capsule for use with a sonic generator includes a deformable membrane adapted to releasably engage the distal end of the elongate horn, a nozzle including at least one delivery opening; a nozzle including at least one delivery opening; and a reservoir containing a liquid composition disposed therebetween. When the unit dose capsule is engaged to the distal end of the elongate horn, the nozzle is disposed in an outwardly facing orientation, and the reservoir is in liquid communication with the at least one nozzle. The unit dose capsule can be included in a kit with a handheld misting device comprising a housing having a dispensing window arranged and configured to contain a sonic generator and a power source.
