Abstract: A method to detect, identify and determine the position of laser points from infrared laser emitters in a firearm training simulation system. The method consists of two steps. This first step combines some common tools such as a camera with a filter switcher and edge and corner detecting algorithms in image processing to provide a fast automatic screen calibrating method. The second step is to detect laser point objects in each frame continuously captured by the camera, and then further process these objects to identify laser shots, filter out noisy objects, and eventually detect simulated shots from different laser emitters and determine the final mapped position of the shot.

Abstract: A gas turbine storage container is composed of a horizontal cylindrical shell with openings at two opposite ends of the cylinder, outside is designed with frames to keep it fixed and has straps to install ropes when hoisting. The inside of the cylindrical shell is pumped with inert gas and contains desiccant. The engine is housed in a mount that can be fixed to the inside of the box, and has wheels to make it possible to move it out of the box. A sensor system that measures the temperature and humidity status inside the cylindrical shell can provide information about the quality of the gas stored in the cylindrical shell in real time without opening.

Abstract: The invention is referred to as a flush toilet with a toilet bowl (1), which has an elliptical shape, with an arbitrary size, large and small, on the outside of the toilet bowl (1) with a trip lever (9), trip lever (9) connected to the connection wire (4) in a fixed plastic tube (3), the connection wire with the flapper (10), a closed clamping mechanism (5) and a opened clamping mechanism (7), the mouth (16) of the toilet bowl (1) has a main water outlet hole (12) and many auxiliary water holes (13) in around the mouth bowl (16) of the toilet bowl (1), below is the toilet seat (2) is made of porcelain, the inside of the toilet seat (2) has the chicken guts exhaust tube (14) attached to the toilet bowl (1), the chicken guts exhaust tube (14) have two segments made from a soft rubber plastic tube, shaped like as chicken guts, with an optimal length from 15 cm to 20 cm and a diameter from 6 cm to 9 cm, two segments of the chicken guts exhaust tube (14) are connected by a connection tube (6b) and fixed vertically
