    摘要： A high speed digital static shift register includes a series-connected pair of resonant tunneling diodes (RTDs) 22, 24 to achieve a bistable operating state. A clocked switch 20 provides the means of setting the binary state of this bistable pair. In order for one bistable pair to drive a following pair, a method of providing isolation and gain using a buffer amplifier 26 between the two pairs of RTDs is also provided. In one embodiment, the buffer amplifier comprises enhancement FET 30 and depletion load FET 28.

    摘要： A disclosed method identifies a subject matter expert in an online community for a business entity. The method is performed at a server having one or more processors and memory. The method identifies a plurality of subject matter areas for postings on a website for an online community, and each posting is assigned to one or more of the subject matter areas. For a first subject matter area a set of users is identified, each of whom has authored a plurality of postings assigned to the first subject matter area. A first user of the set of users is identified as a subject matter expert for the first subject matter area based on a determination that the first user's postings assigned to the first subject matter area have consistently been highly relevant to the first subject matter area over a predefined period of time.

    摘要： A method for auto-cropping includes, creating a saliency map corresponding to a digital image, the saliency map indicating a relevance of pixels within the digital image with saliency values within a number range, a lower end of the number range being less than zero and an upper end of the number range being greater than zero. The method further includes, analyzing the saliency map to find a potential cropping rectangle, the potential cropping rectangle having a maximum sum of saliency values within borders of the rectangle.

    摘要： Systems and methods provide for mixed use of physical documents and a computer, and more specifically provide for detailed interactions with fine-grained content of physical documents that are integrated with operations on a computer to provide for improved user interactions between the physical documents and the computer. The system includes a camera which processes the physical documents and detects gestures made by a user with respect to the physical documents, a projector which provides visual feedback on the physical document, and a computer with a display to coordinate the interactions of the user with the computer and the interactions of the user with the physical document. The system, which can be portable, is capable of detecting interactions with fine-grained content of the physical document and translating interactions at the physical document with the computer display, and vice versa.
