The present invention relates to a portable HIFU skin care device. The portable HIFU skin care device (1) of the present invention is divided into three portions. Firstly, a main body (100) has a rechargeable battery embedded therein, a power button and a step button installed therein for adjusting the intensity of an ultrasonic wave, and a display for displaying the operation states of the device, including the number of shots. In addition, a cartridge (200) is used by being mounted on a head part of the main body (100) and has a HIFU transducer embedded therein. A cradle (300) has a charging part which is installed therein, is capable of charging by being connected with the cartridge (200) and an adaptor, accommodates the main body (100) through a placement groove while the cartridge (200) is mounted to the main body (100), includes a UV lamp for disinfecting the head part of the cartridge (200) when accommodating the main body (100), and charges an internal battery of the main body (100). In an operation state, while the HIFU transducer is linearly moved for each one shot by a piezoelectric motor, a plurality of ultrasonic waves are emitted so as to form a plurality of ultrasonic focal point regions on an object, thereby achieving a skin care effect. In the present invention, the piezoelectric motor (216) is particularly installed inside the cartridge (200).

Pathogens (e.g., viruses or bacteria) within a volume of air can be killed or deactivated using RF energy. A plurality of phase shifters input an RF signal and output a phase-shifted version of the RF signal at their respective outputs, wherein an amount of phase shift introduced by each of the phase shifters is controllable. A phased array antenna has a plurality of microwave radiators, and each of the respective outputs of the phase shifters drives a respective one of the microwave radiators. A controller controls the phase shifters to drive the phased array antenna such that a beam of RF energy emanates from the phased array antenna and sweeps through a volume positioned in front of the phased array antenna, and the beam of RF energy kills or deactivates the pathogens.

The present disclosure provides on-demand agent dispensing patches, kits and related methods. A flexible patch is configured to provide on-demand dispensing of the agent via compression of the patch. The patch comprises: an adhesive layer to removably couple the patch to a surface; at least one reservoir layer overlying the adhesive layer configured to absorb and retain the agent therein; at least one dispenser layer overlying the at least one reservoir layer comprising a plurality of solid portions and an array of a plurality of openings configured to inhibit evaporation of the agent and control a flow of the agent therefrom upon the compression of the patch; and at least one backer layer between the adhesive layer and the at least one reservoir layer being substantially impervious to the agent. The at least one reservoir layer may be void of the agent, which may be provided in a container.

A foot sanitizing assembly includes a housing defined by an outer wall. The outer wall includes a top wall, a bottom wall, and a perimeter wall is attached to and extending between the top and bottom walls. A reservoir is positioned within the housing and contains a fluid. The fluid is a sanitizing agent. A pump is positioned within the housing. A supply conduit is fluidly coupled to the reservoir and to the pump and draws the fluid from the reservoir. A plurality of apertures extending through the top wall. A plurality of dispersant tubes is positioned within the housing. Each of the apertures is fluidly coupled to one of the dispersant tubes and each of the dispersant tubes is fluidly coupled to the pump. The pump receives fluid from the reservoir and ejects the fluid outwardly of the apertures when the pump is turned on.

A sterilization method includes irradiating flexible bags, in particular, bags of the type that can contain solutions of human plasma proteins for therapeutic use. The sterilization method includes electron beam irradiation. An in-line method for filling flexible bags of the type that can contain solutions of human plasma proteins for therapeutic use can use the sterilization method.

An article is provided. The article comprises a nonwoven substrate having a copolymer grafted thereto, and a dried coating adhered to the substrate. The copolymer comprises interpolymerized monomer units of a quaternary ammonium-containing ligand monomer, an amide monomer, and an oxy monomer. The coating comprises a plurality of test microorganisms. Optionally, the coating further comprises a water-soluble or water-dispersible polymeric binding agent. A process challenge device comprising a body having a hollow channel with said article fixed disposed therein is also provided. Methods of using the article or the process challenge device for determining the efficacy of a disinfection process are also provided.

An image forming apparatus includes: sheet feeding trays; an image forming part that includes a fixing part and forms an image on a sheet fed from each of the sheet feeding trays based on a print job; and an acquisition part that acquires information indicating “presence” or “absence” of a possible carrier having a possibility of virus infection in a region where an apparatus main body is installed; and a hardware processor that is able to select an operation mode of the print job from a normal mode and a virus removal mode, and sets an operation mode of the print job to the virus removal mode, wherein in the virus removal mode, a fixing temperature of the fixing part is set to a predetermined temperature, and a heating time for the sheet in the fixing part is made longer than a heating time in the normal mode.

The present invention provides systems and methods for treating agricultural particulates, such as buds, Cannabis buds, herbs, leaves, and the like, with a treatment agent, such as steam, as the agricultural products move forward along a pathway created by a conveyer, in a chamber, enclosed by an aligned ceiling and floor, and oppositely disposed lateral walls. The exposure times to the steam, created by the intervals and lengths in which steam enters the chamber results in the elimination (destruction) and/or neutralization of the pathogens on the agricultural particulates, while the agricultural particulates remain undamaged and active.

A method for generating atmospheric pressure cold plasma inside a hand-held unit discharges cold plasma with simultaneously different rf wavelengths and their harmonies. The unit includes an rf tuning network that is powered by a low-voltage power supply connected to a series of high-voltage coils and capacitors. The rf energy signal is transferred to a primary containment chamber and dispersed through an electrode plate network of various sizes and thicknesses to create multiple frequencies. Helium gas is introduced into the first primary containment chamber, where electron separation is initiated. The energized gas flows into a secondary magnetic compression chamber, where a balanced frequency network grid with capacitance creates the final electron separation, which is inverted magnetically and exits through an orifice with a nozzle. The cold plasma thus generated has been shown to be capable of accelerating a healing process in flesh wounds on animal laboratory specimens.
