Abstract: A load management system for reducing engine lug during transient conditions is disclosed. The load management system may include a driven component, a power source configured to drive the driven component, and a controller in communication with the driven component and the power source. The controller may be configured to: monitor a current intake manifold pressure of the power source and a current load of the driven component, calculate a ratio based on the current intake manifold pressure and a steady state intake manifold pressure of the power source, and start a predetermined time period based on the ratio and the current load during which the power source builds up power to respond to the current load.

Abstract: One embodiment of the present invention relates to a sealing system having a leakage sensing function. A leakage sensing unit is arranged in a sealed space which is formed between sealing members of a sealing device body so as to sense, in real time, whether the sealing members are leaking, wherein a sensing value of the leakage sensing unit can be transmitted to the outside by using a communication unit.

Abstract: A pressure regulator for a paint ball gun includes a cylinder, a piston unit, an elastic member, a top connector and a switch bolt. The cylinder includes upper and lower chambers. The piston unit includes a ring plate and a tube. The ring tube is disposed in the upper chamber. The tube inserts through the separation plate. The tube has a closed lower end and is provided with a side hole near the lower end. The switch bolt is provided with a cylindrical opening in the upper section. The piston unit and the elastic member are accommodated in the cylinder. The top connector is fastened to the upper chamber. The elastic member holds against the ring plate and the separation plate. The switch bolt is fastened to the lower chamber. The tube slides into the cylindrical opening.
