An air cleaner is provided that may include a cylindrical case including an inlet through which air is suctioned in a radial direction into the cylindrical case; a filter configured to be detachably provided in the case and having a cylindrical shape; and a filter frame configured to support the filter. The filter frame may include a lower frame provided at a lower portion of the filter; an upper frame provided at an upper portion of the filter; and a plurality of supporting frames that extends toward the upper frame from the lower frame. An entry portion for the suctioned air may be formed between the plurality of support frames, the entry portion being configured to receive the filter.

An air flow controller for an air cleaner and an air cleaner are provided. The air flow controller may include a fan, and a housing, the fan being provided in the housing and the housing being movable from an initial horizontal position in which the air flow controller directs air flow in a vertical direction to an inclined position in which the air flow controller directs air flow in a diagonal direction.

An air cleaner is provided. The air cleaner may include at least one air cleaning module including a fan, a filter and an inlet through which air is suctioned into the filter; an air flow controller configured to be movably disposed on the at least one air cleaning module and including an air flow control fan to control a flow of the air discharged from the at least one air cleaning module. The air flow controller may be movable from a first position at which the air is discharged in an upward direction to a second position at which the air is discharged in a diagonally upward direction.

A liquid dispensing method including steps of: providing a dispensing device having a refill time (RT) and repeatedly energizing the activation elements at a frequency greater than about 1/(RT). The device includes: a plurality of liquid dispensing elements, each element including: a chamber having a height (H), a nozzle having a diameter (D), an activation element having a length (L), and the refill time (RT); a liquid containing reservoir in fluid communication with the liquid dispensing elements; and a control element in electrical communication with the liquid dispensing elements. The ratio of the nozzle diameter (D) to chamber height (H) is between about 3 and about 10.

The present invention generally relates to an x-ray source and specifically to an x-ray source suitable for large area x-ray generation. The invention also relates to a system comprising such an x-ray source.

The present invention relates to a control mechanism (10) for a dispensing device (50). The control mechanism (10) includes a motor (12), a gear arrangement (14) operably connected to the motor (12); and an actuator (15) operably connected to the gear arrangement (14). In use, the actuator (15), under the operation of the motor (12), is configured to actuate an outlet (38) of a container (40) to dispense fluid from within the container (40). The gear arrangement (14) is configured such that a low torque motor (12) may be used to dispense the fluid.

An air treatment device having a flexible air hose, duct or gooseneck member. The air hose, duct or gooseneck member permits an inlet end thereof to be positioned in proximity to a patient so that a negative pressure can be created around the patient so that air can sucked or vacuumed into the system whereupon it is treated as the air flows through the system.

The disclosure herein concerns a method including receiving at a computer at least one target value of a scent parameter for an environment that is remote from the computer, receiving at the computer a sensed parameter of the environment, and controlling, via the computer, diffusion of a liquid from a source of the liquid in fluid communication with at least one scent diffusion device to achieve the target value of the scent parameter, wherein controlling includes setting or adjusting an operation parameter of the at least one scent diffusion device in response to the sensed parameter.

A man-free sterilization system control device, circuits, a method and control modules, including a switch control module, a system control module, the first control circuit, the second control circuit and the third control circuit; the system control module respectively connects with a switch control module, the first control circuit, the second control circuit and the third control circuit; the device judges whether there are people in the room in the order of operation of three control devices set indoors, at the door and outdoors, the UV light turns on when it is confirmed that there is nobody in the room, the device turns off the UV light man-freely when it is judged that there may be people in the room. With the turning-on mode and the man-free turning-off function of the device, the UV light can only be turned on for sterilization when there is nobody in the room.

Introducing ultraviolet (UV) light to interior portions of footwear alters the environment inside a shoe or other footwear to destroy microorganisms or inhibit their growth. Visible light can also be used to prevent further microorganism growth. Introducing forced air flow through the footwear removes dampness in and thereby deodorizes the footwear. A preferred embodiment comprises an adjustable shoe tree equipped with a UV germicidal light source and electronic safeguards that prevent appreciable leakage of UV radiation outside the shoe.
