Abstract: The present invention is to provide an image analysis method for sensing moving ball, and sensing device using same significantly improving the speed of image processing by performing image analysis by applying an analysis object area set immediately before each acquired image to the current image according to a method that setting an analysis object area, which is a partial area, without analyzing the entire image in analyzing an image for sensing a moving ball in sports with balls, detecting the ball within the set analysis object area, calculating the physical quantity of the ball movement, and setting another analysis object area to include the position where the ball will appear on the image to be analyzed based on the position of the ball detected on the image being analyzed.

Abstract: Disclosed is a hot stamping device and method for preventing plating from sticking to a die. The hot stamping device may include a die that receives a heated plating material, presses the received plating material, and rapidly cools the pressed plating material in a constrained state. Before the plating material is pressed, an anti-sticking layer may be formed on the surface of the die disposed in contact with the plating material.

Abstract: Disclosed are a pilot operated safety and relief valve (POSRV) performance evaluation test apparatus, which can test performance evaluation of a POSRV in a structurally stable state, and cope with various sizes of a lift cylinder or a spring-loaded pilot valve, and a control system of the POSRV performance evaluation test apparatus, which can prevent an inside of the lift cylinder from being suddenly pressed and thus damaged and at the same time more precisely evaluate the performance of the POSRV.

Abstract: In a method of controlling transmitting and receiving buffers of a network controller and a network controller operating under such a method, at least one request for access to a system bus from the transmitting buffer and the receiving buffer is received, and the occupancy level of data in the receiving buffer and the vacancy level of data in the transmitting buffer are determined. Access to the system bus is granted based on the determination result. Buffers in the transmitting and receiving paths are treated as a single virtual transmitting buffer and a single virtual receiving buffer, respectively. Bus priority is determined by the data occupancy level in each virtual buffer and any change in the occupancy level. Therefore, it is possible to prevent or reduce underflow of the transmitting buffer and overflow of the receiving buffer, thereby impartially arbitrating which of the buffers can access the memory.

Abstract: A transceiving network controller that controls memory allocation of a buffer memory according to data flow and a method for controlling memory allocation and data flow.

Abstract: In a method of controlling a transmitting buffer and a receiving buffer of a network controller and in a network controller operating under such a method, at least one request for access to a system bus from the transmitting buffer and the receiving buffer is received, and the occupancy level of data in the receiving buffer and the vacancy level of data in the transmitting buffer are determined. Access to the system bus by the transmitting buffer or the receiving buffer is granted based on the determination result. According to the method and system, buffers in the transmitting path and buffers in the receiving path are treated as a single virtual transmitting buffer and a single receiving virtual buffer, respectively, and bus priority is determined in consideration of the occupancy level of data in each virtual buffer along with any increase or decrease in the occupancy level.
