The single camera can acquire digital images of a retinal region of an eye, and digital images of a corneal region of the eye. The camera includes a first combination of optical elements for making said retinal digital images, and a second combination of optical elements for making said corneal digital images. In a preferred embodiment, a portion of these elements are shared elements including a first objective element of an objective lens combination, a digital image sensor and at least one eyepiece for viewing either the retina or the cornea. Also, preferably, the retinal combination also includes a first changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said retinal region at or approximately at a common image plane. Also, preferably, the retinal combination also includes a retinal illuminating light source, an aperture within said frame and positioned within said first combination to form an effective retinal aperture located at or approximately at the lens of the eye defining an effective retinal aperture position, an infrared camera for determining eye position, and an aperture adjustment mechanism for adjusting the effective retinal aperture based on position signals from said infrared camera. Also, preferably, the cornea combination of elements includes a second changeable element of said objective lens system for focusing, in combination with said first objective element, portions or all of said cornea region at or approximately at a common image plane.

摘要： Methods and computer programs for logic circuit design minimization with Identity cell representation is provided which can simplify logic circuit design by combining and minimizing Identity cells and thereby reducing the number of gates in the logic circuit. All possible Identity cells from a given logic function are generated by combining every possible pair of logic terms, then equivalent Identity cell terms are eliminated and the best subset of Identity cell terms which covers all the minterms of the given logic function is provided.The I-cell term representation is sufficiently broad in its scope to allow representation of sub-functions such as ABC+ABC as a single entity that can be readily used for minimization which may be advantageously used in logic circuit fabrication and design. Since I-cell representation includes sum of products, EXOR, EXNOR and other logic terms, fewer terms will be needed to represent a given Boolean function, and a much more simplified, inexpensive and advantageous optimal logic design structure will be obtained.

摘要： The processing time and memory in converting scanned images to a hardware scription language is significantly reducer by using a "peephole" method to examine only partial images of features of the scanned image that is to be converted. The present method generated minimized feature templates (MFTs) by systematically removing all non-feature image pixels. In particular, the method and apparatus of the present invention establishes pattern estimates from image samples, eliminates unnecessary image pixels using off-line statistical analysis, and extracts feature templates from the larger size image patterns. Pattern recognition is then conducted by processing a few pixels of the unknown image pattern. An application of this technique is to recognize drawing symbols, such as, AND, NAND, OR, NOR, XOR, and XNOR gates, buffers, inverters, registers, and I/O pins from scanned images of electronic drawings.

摘要： A cutting tool includes a body including a connecting end, a cutting end which includes a space for receiving the work piece, at least one projection with a ridge defining at least one cutting edge for cutting the work piece, and at least one slot for allowing pieces trimmed from the workpiece to exit from the body. The space has a top and a bottom and tapers outwardly from the top to the bottom. The at least one cutting edge has a first end adjacent to the top of the space and a second end adjacent to the bottom of the space and extends from the first end to the second end obliquely. The body is rotatable about a first axis, and the first axis extends longitudinally between the first and second ends of the body.

摘要： A rotation control device for a tool is disposed between a handle and a tool head and includes two ratchet wheels, a spring and two C-shaped snap rings. The two ratchet wheels are symmetrically arranged. When pressed, the respective ratchet wheels will be subjected to the same force and move the same distance, thus making the engagement between the ratchet wheels and the tool head more assured while avoiding the stuck fault and improving the convenience in use.
