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： A light delivery technique includes optical configurations as well as the associated methods that generate a ring beam from a linear light source. In one embodiment, a remote light source module delivers illumination light to a fundus camera and/or slit lamp. In another embodiment, an arrangement combines the use of a light pipe homogenizer and a ring beam transformer for efficiently collecting light from a substantially axially linear light source, homogenizing the collected light that lacks low angle flux relative to the optical axis, and transforming the light into a ring beam with a substantially improved low angle flux distribution. In still another embodiment, light emitted from a substantially axially linear light source is directly collected by a curved surface mirror and spatially filtered into a ring beam. The ring illumination beam can be co-axially projected on a sample such as the pupil of a human eye and at the same time the light beam also has a large enough relatively uniform angular flux distribution so that a wide area on the retina of the eye can be uniformly illuminated.

摘要： Proportional-delayed zero-crossing frequency-drift estimator devices are provided. Given N-number of time samples, the current zero-crossing time estimation technique uses only two zero-crossing time samples for repetition-rate estimation. The term “zero-crossing point” refers to the point where a sinusoidal waveform varies from a positive to a negative value and crosses the zero value in the process. The proportional-delayed zero-crossing frequency-drift estimator devices employ four zero-crossing time samples by utilizing both proportional zero-crossing points for current information and delayed zero-crossing points for past information so that the noises in the time samples will be smoothed out making a less noisy estimation. The proportional-delayed zero-crossing frequency-drift estimators are composed of a hysteretic nonlinear converter, a zero-crossing time-difference counter, a group of shift registers and adders, a repetition-rate algorithm, a reciprocal operator and a means for differentiation operation. A number of different embodiments are provided, but all embodiments include a hysteretic nonlinear converter which enhances the zero-crossing features and blocks the signal random noise so that the zero-crossing point is measured more accurately.

摘要： N-sample level-crossing estimator methods and devices are provided that extract more information from given time samples than the current two-sample approach and that are more resistant to interference from noises. The two-mean level-crossing time-interval estimation method extracts more information from given time samples than existing methods, advantageously estimates a level-crossing time interval with a limited number of time samples and is quieter than current noisy estimation techniques. The two-mean level crossing time-interval estimation method for N-sample estimation uses all N time samples by calculating the mean value of the first N/2 time samples and subtracting it by the second N/2 time sample to average out the noises in time samples. The two-mean level crossing time-interval estimation method can be implemented by using a Finite Impulse Response filter to take level-crossing time samples as inputs, take the differential level-crossing time samples as inputs, or take the N/2-step differential level-crossing time-interval as an input. An addition only one-step differential level-crossing time-interval estimator device and a one-step differential level-crossing time-interval estimator device are also provided.

摘要： Passage-separated intake of the present invention refers to that a separate supercharged intake passage and a separate supercharged intake supply apparatus are provided such that natural intake is separated from supercharged intake to implement respective intake without mutual interference. Time-separated intake refers to that in order to avoid a cylinder C from becoming a passage between natural intake and supercharged intake, natural intake is performed first in an intake stroke, and supercharged intake is performed after a bottom dead center of the intake stroke at the end of the natural intake. The efficiency of supercharged intake in this case is
