  • Patent number: 9183846
    Abstract: A method and device for adaptively adjusting sound effect, and the method comprises: obtaining an energy value of the current ambient noise; receiving a first trigger instruction and adjusting the current output volume based on the energy value of the current ambient noise; while judging that the energy value of the current ambient noise is bigger than a first threshold, processing treble enhancement; while judging that the energy value of the current ambient noise is less than a second a sound threshold, processing bass enhancement. By collecting the voice data and detecting the speech activity on the voice data, when the first trigger instruction is received, the method can adjust the current volume and adjust the frequency response by the treble enhancement or the bass enhancement based on the energy value of the current ambient noise, thereby obtaining the better sound effect and easy to achieve.

  • Patent number: 8345985
    Abstract: In an electronic device and method of matching an image A and an image B, grayscale centers of the image A and the image B are computed. The image A is divided into n equal parts Dk(k=1˜n) according to the grayscale center, and a grayscale density Vk of each part Dk is computed, to acquire n grayscale densities Vk(k=1˜n) which are regarded as feature data u of the image A. Feature data v of the image B is extracted in the similar way. A similarity of a grayscale density Vak selected from the feature data u and the grayscale density Vbk selected from the feature data V, is computed. Thus, n similarities are computed. A similarity ?(n, u, v) of the image A and the image B is computed according to the n similarities.

  • Publication number: 20120204274
    Abstract: A myeloid-specific c-fms-rtTA/(TetO)7-CMV-MMP12 bitransgenic mouse model was created. Induction of MMP12 abnormally elevated frequencies and numbers of common myeloid progenitor (CMP) and granulocyte/macrophage progenitor (GMP) populations, and decreased the frequency and number of the megakaryocyte/erythrocyte progenitor (MEP) population in bone marrow. CD11b+/Gr-1+ immature cell population increased in multiple organs. An immunosuppressive function on T cell proliferation and function by CD11b+/Gr-1+ immature cells was seen in vitro and in vivo from MMP12 over-expression. MMP12 stimulated (Lin?) progenitor cells to differentiate into CD11b+/Gr-1+ immature cells showing immunosuppression on T cell proliferation and function in vitro. Regulatory T cells were increased. In the lung, concentration of interleukin (IL)-6 was increased, which activated oncogenic signal transducer and increased expression of Stat3 downstream genes in epithelial tumor progenitor cells.
