Patent number: 8896712Abstract: A system and method for determining and correcting for imaging device motion during an exposure is provided. According to various embodiments of the present invention, multiple sets of image pixels are defined on an image sensor, where each set of pixels is at least partially contained in the output image area of the image sensor. Signals from each set of image pixels are read out once or more during an exposure, motion estimates are computed using signal readouts from one or more sets of image pixels, and signal readouts from one or more sets of the image pixels are processed to form the final output image.Type: GrantFiled: July 20, 2007Date of Patent: November 25, 2014Assignee: OmniVision Technologies, Inc.Inventors: John N.

Patent number: 8618458Abstract: A back-illuminated image sensor includes a sensor layer disposed between an insulating layer and a circuit layer electrically connected to the sensor layer. An imaging area includes a plurality of photodetectors is formed in the sensor layer and a well that spans the imaging area. The well can be disposed between the backside of the sensor layer and the photodetectors, or the well can be a buried well formed adjacent to the backside of the sensor layer with a region including formed between the photodetectors and the buried well. One or more side wells can be formed laterally adjacent to each photodetector. The dopant in the well has a segregation coefficient that causes the dopant to accumulate on the sensor layer side of an interface between the sensor layer and the insulating layer.Type: GrantFiled: November 7, 2008Date of Patent: December 31, 2013Assignee: OmniVision Technologies, Inc.Inventors: John P.

Patent number: 7571551Abstract: A tool that enables workers to pull up trusses from a stored position to their upright position and then automatically space them correctly. It has a rectangular body that has markings on it for proper spacing and a pair of clamp members attached. One of the clamp members is fixed at the end of the body. The second clamp is adjustable as desired to achieve the correct truss spacing. The clamps can have spring clips on them to ensure a tight hold on the truss. At the rear of the body is an extension handle. This handle is pulled out of the rear of the device to the desired length. The extension handle is used provide workers enough space to be able to easily lever up a truss.Type: GrantFiled: December 11, 2007Date of Patent: August 11, 2009Inventor: Todd J. Anderson
