| 20090169699 | METHODS FOR SEPARATING CASEIN FROM SOLUBLE PROTEINS IN A COMPOSITION - Methods for separating casein from soluble proteins in a composition. The method includes: adding a phosphate solution to the composition, mixing to form a mixture, freezing the mixture to obtain a frozen mixture, thawing the frozen mixture to obtain casein-containing aggregates in the mixture, and then centrifuging the mixture to obtain a supernatant traction and a casein-precipitate fraction. The supernatant fraction contains the soluble protein, which may be isolated by subjecting the supernatant fraction to a purification process. The method can be applied to purify a recombinant protein from the milk of a transgenic mammal. | 07-02-2009 |

| 20090002533 | Apparatus of high dynamic-range CMOS image sensor and method thereof - The present invention discloses an apparatus of high dynamic-range CMOS image sensor and method thereof. The present invention utilize a pixel circuit outputting an output signal, wherein the pixel circuit has a photodiode and a plurality of transistors; and utilize a current source as a charge supplement unit to supply current into one end of the photodiode, and providing charges to the parasitic capacitor of the photodiode to delay saturation in the pixel circuit. In addition, a feedback circuit can be further designed connecting the pixel circuit. The feedback circuit receives the output signal from the pixel circuit and then outputs a control signal according to the output signal of the pixel circuit to control status of the charge supplement unit, and thereby increasing the dynamic range of the CMOS image sensor. | 01-01-2009 |
