Abstract: In a high pressure gas charging system and method, the system includes a charging container, a fluid supply part and a high pressure charging part. A high pressure gas is charged in the charging container. The fluid supply part is connected to a first side of the charging container, and is configured to supply incompressible fluid into the charging container before charging the high pressure gas. The high pressure charging part is connected to a second side of the charging container, and is configured to charge the high pressure gas into the charging container in which the incompressible fluid is already supplied. The incompressible fluid is supplied to the charging container until an inner pressure of the charging container reaches a predetermined pressure, and the incompressible fluid is removed to outside through the fluid supply part as the high pressure gas is charged into the charging container.

Abstract: An apparatus for controlling object tracking and a method therefor are provided. The apparatus includes an object detector configured to detect an object in an image, an object tracker configured to track the object, a learning device configured to learn whether to enable the object detector based on features of the object and tracking results of the object tracker, and a controller configured to determine whether to enable the object detector by interworking with the learning device.

Abstract: A battery module includes a first member and a second member that are coupled in directions that cross each other, wherein the first member and the second member are weld-coupled; a welding portion of the first member and the second member includes a first welding portion formed on the first member and a second welding portion formed on the second member, based on a coupling surface of the first member and the second member; and the first welding portion and the second welding portion have shapes that are asymmetric to each other.

Abstract: A polyp detection apparatus and a method of operating the same are provided. The method of operating a polyp detection apparatus includes: generating an image of an object; detecting a polyp candidate region based on the generated image; detecting a reflected light region within the detected polyp candidate region; and displaying a final polyp region by excluding the detected reflected light region from the polyp candidate region.

Abstract: A method for controlling anomalous dual state of duplicated processors for a fault-tolerant system having a first and a second processors that are connected to each other through network, comprising: a first step of transmitting its own state information of either the first or the second processor to mutually another processor (twin) by using different transmission period to each other; a second step of receiving the heartbeat applied from the other processor and recognizing state information of the twin; and a third step of performing duplication states according to the state information of the twin. By doing that, when the two processors start, the seeds for random numbers are differently allocated to generate different random numbers, and the heartbeat transmission period is continuously changed by using the random numbers to differentiate the transmission and receiving time of the heartbeat between the two processors.

Abstract: A booster for a transmission gear box has an actuating rod cooperating with a gearshift lever and a hollow piston rod movably penetrating the pneumatic cylinder and cooperating with the actuating rod. A connector is mounted to the piston rod and introduces and discharges pressurized air into and from the piston rod. A striker is coupled to the actuating and piston rods through a pin and is coupled to a connecting lever of the gear box to allow the connecting lever to be operated in conjunction with the actuating and piston rods. The booster prevents a relative rotating motion between the actuating and piston rods, simplifies the gearshift part of the gear box, smoothly engages and disengages gears to the gear box with a small force and provides an easily-machinable hollow piston rod.
