Abstract: A nasal device (10-16) for obesity prevention and treatment and its method of use are disclosed. The device comprises a check valve (20, 20?) and a cylindrical or conical airtight tube (30, 32?, 33, 34, 34?/36?) with an opening at each end. The valve is so fastened or connected to the tube at one end as to form a one-way air channel/passage. The tube conforms to or fits the interiors of different nostrils air-tightly in a variety of ways (32?, 34, 38, 40, 34?, 40?, 46). A pair of such devices can be connected with a flexible strip (42) or a band (44). Inserting the device into the nostril, a wearer can inhale through the nose but has to exhale through the mouth. This reduces the wearer's appetite for food and slows down eating. The wearer can easily remove the device after eating or whenever desired.

Abstract: A system and method for online monitoring partial discharge of a generator are disclosed.

Abstract: An internal valve (10, 10? or 10?) and its methods of use for stabilizing and reinforcing inflatable objects are disclosed. The internal valve is a novel, simple modification to conventional check valves with the addition of a discharging means for external control (14, 22 or 28). An internal supplemental chamber comprises one or more partitions that are secured, directly or by I-beams (40?), to main chamber's walls (40) of an inflatable object and stretched when the main chamber is inflated. With the internal valve as the passage to and from the main chamber, the enclosed or isolated supplemental chamber (30, 30?, 32, 34, 36 or 38) functions as a stabilizing or reinforcing component. A plurality of chambers 36 can form cylinder beams for an inflatable mattress.

Abstract: An inflatable device (10, 11, 12, 13, 14, 15, 16, 17 or 18) both for vaginal cleaning and hygiene and for sexual aid and its methods of use are disclosed. The device comprises a pouch or bladder (30 or 30?) with an open-end or opening (34 or 34?) and in substantial shape and size of the condom and a standard valve (20 or 20?) or the like (20?) with a base (22, 22? or 22?). The bladder is made of a layer of flexible and inelastic airtight durable material. The opening is air-tightly sealed with the base. The inflated device functions as dildos and, when enclosed in a micro-vibrator, as vibrators. The poked device is used for delivering medication to appropriate areas of the vagina and for washing the vagina with water. The device is packed in a small sealed package before use and is disposable after use.
