  • Publication number: 20130041278
    Abstract: A method for diagnosis of diseases adopted on an electronic stethoscope which includes at least two sound receiving portions, a noise control portion, a processing portion, a data portion and an output portion. The method includes: first, the sound receiving portions receive sound signals issued from a patient's lungs included external noises; next, the sound signals are sent to the noise control portion which eliminates the external noise, and the processing portion to be overlapped and intensified; then characteristic values are retrieved from the sound signals to be compared with disease sound signal data in the data portion; finally the output portion outputs a diseases judgment result. Thus the electronic stethoscope can perform automatic interpretation of diseases to reduce human erroneous diagnostic judgment. Users also can get preliminary understanding of their body conditions when doctors are absent.

  • Patent number: 8369565
    Abstract: In some aspects, message data is generated from a first representation of a message and a reference image. The message data is generated to hide the message such that generating a second representation of the message from the message data requires processing of a second image that is perceptually similar to the first image. In some examples, a degree to which the second representation of the message is perceptually similar to the first representation of the message is related to a degree to which the second image is perceptually similar to the first image.

  • Patent number: 8242519
    Abstract: A package structure of a light emitting diode for a backlight comprises a long-wavelength LED die and a short-wavelength LED die. The lights emitted from the two LED dies are mixed with the light emitted from excited fluorescent powders for serving as the backlight of a liquid crystal display. A partition plate is disposed between the two LED dies for separating them from each other. The effective light output of the package structure is increased because each of the two LED dies cannot absorb the light from the other.
