  • Patent number: 8678255
    Abstract: A personal portable devices keeper (10) and its method of use are disclosed. The keeper mainly comprises a housing formed by a shell (12) and a base (14), a spool assembly (16) controlled by a spiral spring (18) and a ratchet mechanism consisting of a ratchet plate (32) in the spool, a ratchet bead (20), and a straight slot (50) in the base, a clip (22), and a length of cord (24) with a bob (72) securing a strap loop (90). The shell has a cord port (28) and is rotatable independently from the spool so that the cord remainder is adjustable even after the cord is fully retracted by the spring. The strap loop ties a personal portable device directly through its strap holder or the like. The keeper is fully operable through the cord dragged by the portable device that is normally held and operated by one hand.

  • Patent number: 8271213
    Abstract: A system and method for online monitoring partial discharge of a generator are disclosed. The system is connected in parallel with a busbar between the generator and electric network, includes: a near-end circuit on a generator side, which includes a near-end capacitive coupling sensor connected to the busbar and a near-end impedor connected in series with the near-end capacitive coupling sensor; a far-end circuit on an electric network side, which includes a far-end capacitive coupling sensor connected to the busbar and a far-end impedor connected in series with the far-end capacitive coupling sensor; and a detection device, which has a near-end input terminal connected to a connection point between the near-end capacitive coupling sensor and the near-end impedor through a near-end cable, a far-end input terminal connected to a connection point between the far-end capacitive coupling sensor and the far-end impedor through a far-end cable, and a processing unit.

  • Publication number: 20110100369
    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.

  • Publication number: 20090014072
    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.

  • Publication number: 20090005635
    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.
