Abstract:
A power closing assembly operates a closure panel hingedly secured to a motor vehicle. The power closing assembly includes an actuator mounted to the motor vehicle, a movable striker also mounted to the motor vehicle to receive the closure panel's latch, and a rotary power cable connecting therebetween. The actuator has a closure cable on a spooling drum extending to the closure panel for closing from an open position when the actuator operates. The movable striker moves between a nominal inboard position and an outboard position. A rotary power cable connects between a provided output on the actuator and an input on the striker so that the striker's movement is powered and synchronized by the actuator. With the closure panel open, the actuator begins a closing cycle by driving in a direction to spool in the closure cable extending to the closure panel. The actuator's direction, using the rotary power cable, simultaneously causes the striker to move outboard. When the closure panel is pulled completely closed, the striker has also moved to its outboard position whereupon the closure panel's latch readily receives and engages the striker. Upon engagement, the actuator reverses its drive direction. This reverse direction causes both the actuator to reset with respect to its closure cable spooling drum and the rotary power cable to turn in the other direction causing the striker to return to its inboard position and fully close the closure panel against its seal load.

Abstract:
A drive assembly moves a vehicle closure panel from an open to a closed condition. The drive assembly has a housing and a motor mounted on the housing. A drum and gear assembly is rotatably mounted on the housing. The drum and gear assembly has a drum having a helical groove, a gear in driving engagement with the motor, and a spring biasing the drum in a winding direction relative to the gear. The drum and gear have a lost motion connection therebetween. A cable has an end connected to the closure panel and an opposite end connected to the drum about the helical groove in the winding direction. The drum rotates in the winding direction relative to the stationary gear as the closure panel is manually moved from the open to the closed condition with the spring maintaining a cable tension. The drum and gear rotate together in the winding direction upon energizing the motor effecting powered movement of the closure panel to the closed condition. The motor is afterwards energized in an opposite direction counter-rotating the gear relative to the drum back to a start position.

Abstract:
A notebook computer hinge with spring opener is provided. The shaft has a C-shaped stopper ring with an offset notch in the middle section, which allows the coupling block of the rotatable bracket to be engaged by the notch. A spring is mounted on the outer edge of the rotatable bracket through a common shaft. As the display panel is lowered towards the computer body, the coupling block presses against the stopper ring and a torsional force is accumulated by the spring. The force will be released once the notebook computer is opened, enabling the display panel to be separated from the computer body with an appropriate angle, thus providing extra convenience for notebook computer users.
