Abstract: Stationary UV light therapy apparatus for treatment of vitamin D deficiency, comprising: a daylight and/or sunlight collector for collecting daylight and/or sunlight over a collector square area, a light transmission component for transmitting the light collected by the collector to the interior of a room of a building, an optical filter for transmission of UV-light included in the daylight and/or sunlight, and a light distributor for distributing the UV-light over a square area of the room, wherein the square area is a part or all of the room square area and larger than the collector square area, and building comprising the same.

Abstract: The sequential compression device for treatment and prophylaxis of deep vein thromboses includes a compression sock having a plurality of electromechanical units positioned along the calf muscle of a user's leg. Each of the electromechanical units includes a front housing component and a back housing component. The front housing component of the unit includes a compressor piston positioned in communicating relation with the user's calf muscle and the back housing component of the unit includes a magnet and a copper coil. The magnet is positioned in communicating relation with the compressor piston of the front housing component. Upon activation, the compressor piston selectively compresses the small saphenous vein to simulate the effect of the calf muscle during walking and promote the flow of blood back to the user's heart.

Abstract: The storage tank cleaning machine is a mobile unit mounted on a trailer for towing by a suitable vehicle. The machine is positioned adjacent the access opening of the tank, e.g., a water tank, cistern, or other storage tank, and a support on the bed of the machine is raised to vertical over the opening. A multiple segment articulating arm extends from the support and is lowered through the opening to access the interior of the tank. A motorized rotary brush extends from the distal end of the arm. Distance sensors adjacent the brush detect the interior surfaces of the tank for accurately positioning the brush. An electronic control system is provided. A tank for water and/or other cleaning fluid and a disinfectant tank are also provided. Fluids used during the cleaning operation are suctioned back to the machine, where the fluids are cleaned and recycled.

Abstract: The mattress for relieving pressure ulcers includes a first sponge layer, an air mattress layer over the first sponge layer, an intermediate layer over the air mattress layer, a second sponge layer over the intermediate layer, and a paper sheet layer over the second sponge layer. The sponge layer and the air mattress layer are configured to increase the contact area of the patient's body with the bed, according to a patient's weight. The intermediate layer is a rubber layer configured to provide ventilation for areas of the mattress that contact a patient's body using dry air or dry air mixed with ozone gas, essential/volatile oil, and/or antibacterial vapors. The second sponge layer is designed to distribute the air under the patient's body. The paper sheet layer is configured to provide alarms in the event the mattress gets wet due to sweating or incontinence.
