Abstract: An optical imaging system includes a first lens, a second lens, a third lens including a concave object side surface, a fourth lens, a fifth lens, and a sixth lens sequentially disposed from an object side toward an image side. The optical imaging system satisfies 0.7<TL/f<1.0 and F No.<2.1, where TL is a distance from an object side of the first lens to an imaging plane, f is a total focal length of the optical imaging system, and F No. is the F No. of the optical imaging system.

Abstract: A depth-wise convolution acceleration device using an MAC array processor structure according to the present invention may include a data output unit, which receives a data of each row of the image from the data buffer and inputs the data into convolution operation blocks while shifting the data N?1 times according to the kernel size (N×N) and a weight output unit, which receives the kernel data from the kernel buffer and sequentially inputs a weight value constituting the kernel data to each of the row convolution operation blocks, and inputs the weight delaying by N clocks if the row increases as N rows.

Abstract: A lens assembly includes a lens barrel, a plurality of lenses arranged inside the lens barrel along an optical axis, and a cover member fixed to an end of the lens barrel on a subject side and fixing a last lens of the plurality of lenses on the subject side, wherein outer diameters of the plurality of lenses decrease from the subject side to an image side, and an outer diameter of the lens barrel is constant or smaller from the subject side to the image side.

Abstract: An electronic device including a touch-enabled display module configured to display a plurality of windows according to a multi-window mode; and a control module configured to displaying on the touch screen a first application window and a second application window according to the multi-window mode, alter the first application window in response to a touchscreen input received via the touch-enabled display, and automatically alter the second application window in response to the alteration of the first application window.

Abstract: A cathode active material for a lithium secondary battery according to an embodiment of the present disclosure includes first lithium metal phosphate particles, each first lithium metal phosphate particle having a secondary particle shape formed by aggregation of primary particles and having an average particle diameter (D50) in a range from 5 ?m to 10 ?m, second lithium metal phosphate particles, each having a single particle and having an average particle diameter in a range from 1 ?m to 3 ?m, and third lithium metal phosphate particles, each having a single particle shape and having an average particle diameter less than 1 ?m.

Abstract: An optical imaging system is provided. The optical imaging system has a first lens, a second lens, a third lens, and a fourth lens disposed in order from an object-side to an image-side. The optical imaging system satisfies the following conditional expressions: F No.?1.5, 0.5<EPD/TTL<0.7, where EPD is an entrance pupil diameter, and TTL is a distance from an object-side surface of the first lens to an imaging plane.

Abstract: A substrate processing apparatus includes a photoresist coater applying a photoresist film on a substrate, a humidifier increasing an amount of moisture in an ambient to which the photoresist film on the substrate is exposed, and an exposer irradiating the photoresist film exposed to the ambient having the increased amount of moisture with light. The humidifier is disposed between the photoresist coater and the exposer.

Abstract: A lens, wherein a first profile in a first direction intersecting an optical axis and a second profile in a second direction intersecting the optical axis are different from each other, and a length of the first profile in the first direction is different from a length of the second profile in the second direction.

Abstract: The present disclosure relates to a work safety management system using a safety belt unit for high-place work, and safety during working at a high place can be enhanced by determining whether a worker has fastened a seat belt to a safety structure, and the location of the worker, whether the seat belt is fastened and whether the work is on progress can be monitored in real time from a remote location to prevent safety accidents.
