  • Publication number: 20140166039
    Abstract: A hair styler and its heating device which can heat the thermal storage piece inside the hair roller quickly to a desired temperature by electromagnetic heating. The thermal storage piece is made of high thermal conductivity material which absorbs heat quite quick and disposed inside the hair roller to prevent the hair from directly contacting the thermal storage piece during hair styling, consequently preventing the hair from being burned. Then a low thermal conductivity isolating layer retains the heat within the hair roller and enables the heat to be uniformly and constantly transmitted to the outer surface of the hair roller, providing an effect of low energy consumption and long-lasting heat. A temperature sensing piece is used to detect and indicate the temperature of the hair styler by using different colors, making it easier for the user to know the temperature of the hair styler.

  • Publication number: 20140116461
    Abstract: A heating apparatus for heating hair curlers is disposed in a housing and clamped by at least one hair clip. The heating apparatus comprises two assembling members and two thermal conductive members which are coupled one another and disposed on a base. Each of the thermal conductive members includes a heating member and an elastic piece for fixing the heating member. Above the assembling members and the thermal conductive members is disposed a cover. The two heating members are closely pushed against the thermal conductive layers of the hair clip, so as to reduce the length of heat transferring route, and consequently improving heating efficiency and enhancing temperature control accuracy. Furthermore, the heating apparatus has a simple structure and can be easily assembled at a low manufacturing cost.

  • Patent number: 8255775
    Abstract: The present invention discloses a candidate list augmentation apparatus with dynamic compensation in the coded MIMO systems. The proposed path augmentation technique in the present invention can expand the candidate paths derived from the detector to a distinct and larger list before computing the soft value of each bit. Consequently, the detector is allowed to deliver a smaller list, leading to reduction in computation complexity. Moreover, an additive correction term is introduced to dynamically compensate the approximation inaccuracy in the soft value generation, which improves the efficiency and performance of the coded MIMO systems.
