  • Publication number: 20110038882
    Abstract: A method for treating or alleviating allergic disease in a mammal in need thereof having administering to the mammal a therapeutically effective amount of a pharmaceutical composition having phycocyanin is provided. A method for modulating balance between Th1 and Th2 immune response in a mammal in need thereof, having administering to the mammal an effective amount of phycocyanin, wherein immune response of the mammal is skewed toward the Th1 immune response is also provided. Phycocyanin from Bangia atropupurea (Ba-PC) is identified to regulate mammalian immunological response indicating that Ba-PC can direct skewed immune response toward Th1 response through modulating DC function, increase proliferative activity of antigen-specific T cells and alleviate airway inflammation, confirming that phycobiliproteins are effective in treating allergic disease.

  • Patent number: 7224718
    Abstract: A wireless system broadcasts data in frames, each frame having F slots. Output from a matched filter is used to combine K slots to generate profile data, where K is less than F. N peak values respectively from n peak positions are selected from the profile data, where n is greater than one. A correlator is employed, together with the n peak positions and S slots subsequent the K slots, to generate n×S correlation values. Respective combination values for the n peak positions are generated by coherently combining the correlation values, and combining the coherent combination results with the non-coherent n peak values. The combination values are respectively used to generate SNR values for each of the n peak positions. The peak position having the best respective SNR value is then selected as a slot synchronization position.

  • Publication number: 20060228102
    Abstract: A photographing apparatus includes an image sensor for capturing first and second images sequentially, the first image including a reference image part; a calculation module for calculating average brightness degree of the reference image part for serving as a reference brightness value, wherein a brightness difference between the reference image part and an adjacent part succeeding the reference image part is greater than a threshold, brightness of the first image and the reference brightness value cooperatively defining a compensation ratio; and a compensation module for compensating brightness of the second image according to the compensation ratio.

  • Patent number: 6632097
    Abstract: The present invention relates to a memory card connection arrangement primarily including a top cover, a side frame and a bottom plate. The top cover contains a plurality of joint flanges and locking grooves, the side frame a plurality of joint holes at the position opposite to the joint flanges and the bottom plate a plurality of hooks at the position opposite to the locking grooves. In assembly, the joint flanges are engaged into the joint holes so that the top cover and the side frame are attached to each other while the hooks are hooked in the locking grooves so that the bottom plate and the side frame are connected to each other. Accordingly, a stable state in whole is achieved and the rims thereof are overlapped to avoid the electromagnetic interference.
