  • 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.

  • Publication number: 20120116770
    Abstract: A speech data retrieving and presenting device applied with an electronic device through a network includes a data receiving unit, a processing unit and a speech presenting unit. The data receiving unit connected to the network receives data of the electronic device through the network. The processing unit coupled to the data receiving unit receives speech data and retrieves a speech presenting signal from the speech data. The speech presenting unit coupled to the processing unit receives the speech presenting signal and outputs a speech according to the speech data. This device can assist a user to obtain network information, and provide the user a more flexible application according to the property that the device can be operated independently by a simple motion.

  • Patent number: 8035930
    Abstract: A side shield structure for a PMR write head is disclosed that narrows write width and minimizes adjacent track and far track erasure. The side shield structure on each side of the write pole has two sections. One section along the ABS and adjacent to the pole tip has a height (SSH1) defined by SSH1?[(0.6×neck height)+0.08] microns. There is a non-magnetic gap layer between the first section and a second section that is formed adjacent to the flared sides of the main pole layer and serves to suction leakage flux from the flared portion and prevent unwanted flux from reaching the first side shield sections. A fabrication method is provided that includes electroplating the first side shield sections, depositing the non-magnetic gap layer, and then electroplating the second side shield sections. Subsequently, a main pole layer and a trailing shield are formed.
