20090171639 | Method to identify modulators for human 3alpha-hydroxysteroid dehydrogenase - 3 α-hydroxysteroid dehydrogenase (3α-HSD) plays a central role in the metabolism and action of steroid hormones and neurosteroids (steroids synthesized in the central nervous system). The high resolution structure of human type III 3α-HSD crystallized in complex with cofactor NADP is determined by X-ray diffraction. Furthermore the active site is determined. The structure coordinates of the enzyme may be used to design and select novel classes of modulators to human type III 3α-HSD. | 07-02-2009 |

20090134954 | DIFFERENTIAL BAND-PASS FILTER HAVING SYMMETRICALLY INTERWOVEN INDUCTORS - One embodiment of the invention relates to a dynamically adjustable differential band-pass filter. This band-pass filter includes a first leg that has an input portion and an output portion with a first inductor therebetween. It also includes a second leg in parallel with the first leg, where the second leg has an input portion and an output portion with a second inductor therebetween. The first inductor is symmetrically inter-woven with the second inductor. In some embodiments, the band pass filter is configured to compensate for losses due to the inductors. Other band-pass filters and methods are also disclosed. | 05-28-2009 |

20150312540 | AUTOMATIC WHITE BALANCING WITH CHROMATICITY MEASURE OF RAW IMAGE DATA - An apparatus and methods for estimating a chromaticity of illumination from raw image data. In an embodiment, one or more image chromaticity weight is determined based on a distance between the raw image data in a sensor chromaticity space and a nearest point within a locus of sensor illumination chromaticities. In a further embodiment, one or more image chromaticity weight is determined based on a disparity among normalized color channel values. In certain embodiments, image chromaticity estimates are utilized to determine a white point estimate for the raw image data. In embodiments, an electronic device including a camera estimates the chromaticity value of raw image data captured by the camera as part of an AWB pipeline. The electronic device may further determine, for example as part of the AWB pipeline, a white point estimate based, at least in part, on the raw image data chromaticity value estimate(s). | 10-29-2015 |
