  • Patent number: 9398972
    Abstract: A posture correction girdle comprises a body wrapping shell, a plurality of pockets and a plurality of paddings is disclosed. The paddings are configured to be inserted into pockets at predetermined positions. Thereby, when the posture correction girdle is worn by the user, pressure is exerted onto a corresponding predetermined section of the user's spine for posture correction purpose. The posture correction girdle further comprises a pair of elastic shoulder straps, an elastic waist strap and a plurality of elongated bones to provide additional support to the user's spine. A micro-system comprising a processor, an output device and a plurality of sensors can also be embedded into the posture correction girdle to provide information regarding the efficiency of the posture correction girdle and the progression of the treatment. Such information is provided to the users using the output device.

  • Patent number: 7510745
    Abstract: Polypyrrole (PPy) is one of the most commonly studied conducting polymers due to its good stability, high conductivity, ease of preparation and non-toxicity. The stability of the conductivity of polypyrrole films depends on the choice of dopant anion, the method of preparation, and the conditions of aging. Most of the existing methods only improve stability by sacrificing conductivity, as well as sensitivity. This invention provides a method for coating conducting polymer onto a substrate by first applying an anionic dopant and an oxidizing agent onto the substrate. The monomer is then allowed to form the conducting polymer at about ?10 to ?80° C. for a sufficient period of time. After storage for a long period of time (nearly a year), the conductive polymer coating still retains almost the same strain sensitivity and at least up to 85% of its initial conductivity.

  • Publication number: 20060174420
    Abstract: A solution for treating fabrics or fibres consists of between 0.1 and 10 percent natural fibre material suspended in distilled water. The solution is used to wet fabrics or fibres for a period of between 1 and 60 minutes. After wetting the fabrics or fibres are dried at a temperature of between 80 and 160 degrees Celsius for between 1 and 10 minutes.
