Abstract: Systems and techniques for using a three-dimension (3D) resist profile aware etch-bias model are described. A 3D resist profile aware etch-bias model can be calibrated based on empirical data. Next, the 3D resist profile aware etch-bias model can be used in one or more applications, including, but not limited to, lithography verification, etch correction, optical proximity correction, and assist feature placement.

Abstract: A computer-implemented method includes characterizing, using the computer, a photoresist profile in accordance with a magnitude of a gradient of an inhibitor concentration disposed in the photoresist.

Abstract: A vision based pedestrian and cyclist detection method includes receiving an input image, calculating a pixel value difference between each pixel and the neighbor pixels thereof, quantifying the pixel value difference as a weight of pixel, proceeding statistics for the pixel value differences and the weights, determining intersections of the statistics as a feature of the input image, classifying the feature into human feature and non-human feature, confirming the human feature belonging to cyclist according to the spatial relationship between the human feature and the detected two-wheeled vehicle, and retaining one detection result for each cyclist by suppressing other weaker spatial relationships between the human feature and the detected two-wheeled vehicle.

Abstract: A lighting system including a powering rod and a first lighting unit is provided. The powering rod is used for providing power. The first lighting unit includes a housing, a light source, an inner ring body and an outer ring body. The light source is disposed inside the housing. The inner ring body, disposed in the housing, has a hollowed portion for receiving the powering rod and is electrically connected to the powering rod. The outer ring body, disposed on the inner ring body fixed to the housing. The outer ring body is capable of rotating with respect to the inner ring body for rotating the housing. When the outer ring body is rotated to a first position, the first lighting unit is in a first lighting state. When the outer ring body is rotated to a second position, the first lighting unit is in a second lighting state.

Abstract: A controlling method for an electronic device having a screen is provided. A first GUI element is displayed on the screen. An operation distance and an operation time between a first object and a second object above the screen corresponding to the first GUI element are detected. Operation functions are selectively performed to the first GUI element by the electronic device according to the operation distance and the operation.
