Systems configured to provide illumination of a specimen during inspection are provided. One system includes catoptric elements configured to direct light from a light source to a line across the specimen at an oblique angle of incidence. The catoptric elements include positive and negative elements configured such that pupil distortions of the positive and negative elements are substantially canceled. Another system includes a dioptric element and a catoptric element. The dioptric element and the catoptric element are configured to direct light from a light source to a line across the specimen at an oblique angle of incidence. The dioptric and catoptric elements are also configured such that pupil distortions of the dioptric and catoptric elements are substantially canceled.

The present invention is a method and system for deriving histograms for neighborhoods of pixels in an image that uses subtractive image regions to increase the size of overlapping regions of regions of series of adjacent image pixels to a size equal to the size of a full neighborhood. Each neighborhood (except for a central neighborhood) is viewed as a combination of the central overlapping neighborhood and one or more additional regions, at least one of which comprises a “subtractive” region, and which vary in size depending on the distance of a pixel from the pixel that is the basis for the central neighborhood. The histogram for each neighborhood is derived by adding the histograms of the central neighborhood and the histograms for the relevant additional region or regions, which may have one or more negative element values. The method and system of the invention allows the processing time for implementing a median filter to be improved to approximately the order of log(r), where r is the “radius” of the median filter being applied.

The invention discloses an automatic control method for making a line film. The automatic control method comprises the steps as follows: 1, determining all parameters and layer names when the line film is made; 2, conceiving and designing a simplified interface to form an input interface; 3, identifying and copying a set of external line layers; 4, optimizing the line layers in line copying layers to remove negative elements; 5, correspondingly compensating and expanding lines, anti-welding plates and copper sheets according to the production capacity in the line copying layers; 6, comparing with plug hole layers, removing holes required to be filled with anti-welding oil in drill layers; 7, compensating and expanding the residual holes in the drill layer, and copying to the line copying layers; 8, automatically generating a set of finished line film tools; and 9, automatically repeating the steps 3 to 8 to form another set of external line films. According to the automatic control method, the tool making time is shortened to be 1-2 min, the working efficiency is greatly improved, the steps are simple and convenient, the making time is short, and the efficiency is high.

This embodiment relates to a lithium-ion secondary battery, which is used to avoid damage to the battery due to overcharging and improve safety and reliability. Inside the battery can are built an electrode assembly formed by winding a positive electrode, a separator, and a negative electrode, and an overcharge prevention mechanism. case; a fuse body provided on the positive lead wire or the negative lead wire; and a switch part, the fuse body and the switch part are connected in series to form a short-circuit circuit of the electrode assembly, when charging When the voltage between the positive and negative electrodes becomes equal to or greater than a predetermined value, the voltage detection unit closes the switch member, thereby blowing the fuse body by energy accumulated in the electrode assembly.

The self-alkylation reaction of isomerized alkane includes making C4-C6 isomerized alkane as material contact with solid catalyst under self-alkylation reaction condition. It features that there is compound containing strong electric negative element in 10-8000 ppm as reaction assistant. The self-alkylation reaction process needs no addition of olefin, and the alkylated product has high branch chain degree and high octane number. No olefin in the reaction makes the catalyst less deactivated.
