Abstract: A method and system for determining a full open position of a closure member of a motor vehicle that articulates between an open position and a closed position includes a left pinch sensor coupled to the left side of the closure member for sensing a pinch condition on the left side of the closure member and generating a corresponding pinch signal. A right pinch sensor is coupled to the right side of the closure member for sensing a pinch condition on the right side of the closure member and generating a corresponding pinch signal. Left and right gas springs are coupled respectively to the left and right sides of the closure member for assisting in articulating the closure member and each of the gas struts has an extension at an end thereof for compressing their corresponding pinch sensor when the closure member is at its full open position.

Abstract: A compact temperature compensating gas spring including a gas filled hollow cylinder and a piston assembly slidably received in the gas filled hollow cylinder. The piston assembly includes a piston head and a piston rod. The piston rod includes a temperature compensation chamber. The piston head includes an aperture formed therein in communication with the temperature compensation chamber. A temperature activated valve is operably connected to the aperture to control gas flow between the cylinder and the temperature compensation chamber.

Abstract: A powered lift assembly and a method of providing a powered lift. The assembly includes a housing including a gas positioned within a chamber. A first piston is slidably positioned within the housing. A second piston includes a shaft. The second piston is slidably positioned within the housing. A motor is operably attached to the first piston. The motor is positioned substantially within the housing. The motor biases the first piston thereby displacing the gas. The displaced gas biases the second piston and shaft. The method includes providing a housing. A first piston force is generated substantially within the housing. A gas pressure is modulated as a result of the first piston force. A second piston force is generated as a result of the modulated gas pressure.
