摘要： In a method of making a generating device, a plurality of spaced apart elongated seed members are deposited onto a surface of a flexible non-conductive substrate. An elongated conductive layer is applied to a top surface and a first side of each seed member, thereby leaving an exposed second side opposite the first side. A plurality of elongated piezoelectric nanostructures is grown laterally from the second side of each seed layer. A second conductive material is deposited onto the substrate adjacent each elongated first conductive layer so as to be coupled the distal end of each of the plurality of elongated piezoelectric nanostructures. The second conductive material is selected so as to form a Schottky barrier between the second conductive material and the distal end of each of the plurality of elongated piezoelectric nanostructures and so as to form an electrical contact with the first conductive layer.

摘要： A system, method and apparatus implementing a multiple-row concurrent readout scheme for high-speed CMOS image sensor with backside illumination are described herein. In one embodiment, the method of operating an image sensor starts acquiring image data within a color pixel array and the image data from a first set of multiple rows in the color pixel array is then concurrently readout. Concurrently reading out the image data from the first set of multiple rows includes concurrently selecting a first portion of the image data from the first set by first readout circuitry and a second portion of the image data from the first set by second readout circuitry. The first and second portions of the image data from the first set are different and the first and second readout circuitries are also different. Other embodiments are also described.

摘要： Feature vectors used in discrimination of images include information on feature blocks of images in an image-document retrieving apparatus of the present invention. Text areas of a page image document are combined to form rectangular images. On the basis of information on the rectangular images that are extracted, a geometric structure of the page is analyzed, the page image document is divided into plural blocks, and then a plurality of feature blocks describing features of the page document image are selected from the plural blocks. The feature vectors are constituted of information on the feature blocks thus selected. This makes it possible to provide an image-document retrieving apparatus and a method of retrieving image documents, by which retrieval of image documents containing mainly text and a graphic is improvable in accuracy.
