One aspect relates to a frameless glass fencing hinge (10) for a frameless glass fencing installation a first leaf assembly (12) for operative attachment to a first glass panel or building structure. The frameless glass fencing hinge (10) includes a second leaf assembly (14) for operative attachment to a second glass panel. The second leaf assembly (14) is operatively adapted to undergo pivotal movement about a hinge axis (16) so as to move the second glass panel between a closed position an open position. The first leaf assembly (12) and the second leaf assembly (14) define a cam formation (16) operatively adapted to cause the second leaf assembly (14) to undergo axial movement along the hinge axis (16) between a rest position and a biased position when the second leaf (14) assembly undergoes pivotal movement about the hinge axis (16).

A one-way braking hinge capable of self-aligning a shaft and a one-way clutch is provided. The one-way braking hinge (10) includes a first leaf (1), a shaft (3) rotatably supported by the first leaf (1), at least one resistance part (4) that resists rotation of the shaft (3), a second leaf (2) rotatably coupled to the shaft (3), a one-way clutch (12) into which the shaft (3) is inserted, and a position adjusting member (11) to which the one-way clutch (12) is fixed. The position adjusting member (11) is position-adjustably coupled to the second leaf (2).

A rotating shaft device, an electronic device and a control method thereof are provided according to the present application. The rotating shaft device includes a driving component and a rotating component. The driving component is configured to receive a control signal, and adjust a torsion force of the rotating component based on the control signal. In the case that the rotating shaft device is applied on the electronic device, various control signals may be provided to control the driving component to adjust a torsion force of the rotating component by the controller, such that the torsion force of the electronic device in a folding or unfolding process is smaller than the torsion force of the electronic device in a state being maintained, which solves the issue of poor user experience resulted from being difficult to fold or unfold and inconvenient to operate.

A one-way braking hinge capable of self-aligning a shaft and a one-way clutch is provided. The one-way braking hinge (10) includes a first leaf (1), a shaft (3) rotatably supported by the first leaf (1), at least one resistance part (4) that resists rotation of the shaft (3), a second leaf (2) rotatably coupled to the shaft (3), a one-way clutch (12) into which the shaft (3) is inserted, and a position adjusting member (11) to which the one-way clutch (12) is fixed. The position adjusting member (11) is position-adjustably coupled to the second leaf (2).

A variable resistance brake clutch facilitates a rotational coupling of electronic device components, and can include a rotatable shaft, a brake disposed proximate the rotatable shaft, and an actuator coupled to and configured to actuate the brake. The brake applies a braking force against a rotational motion of the shaft, and release of the brake results in low to no frictional resistance against the rotational motion. The braking force can be provided by default, and a capacitive touch sensor or other input component can allow a user to actuate the actuator manually to release the brake when desired. The release can be maintained as long as the sensor detects the touch event or other user input. A processor and solenoid can facilitate actuation by on a touch event, which sensor can be located at a back corner of a laptop upper component.
