Clutch assemblies that can provide variable break-away torques are described. An exemplary multi-state clutch assembly can include a shaft, a first frictional element frictionally engaged with the shaft and a second frictional element that can provide variable friction. When the second frictional element provides a low friction, second frictional element can be rotatable relative to the first frictional element, which can remain stationary relative to the shaft. When the second frictional element provides a high friction, it can be secured to the first frictional element. Hence, the first and second frictional elements can be locked together and be rotatable relative to the shaft. Tightening or loosening the second frictional element can vary the overall break-away torque provided by the clutch assembly. The multi-state clutch assembly can be in communication with a sensor or a switch that can respond to a user to change the friction of the clutch assembly.
A clutch assembly that pivotally couples a first portion and a second portion of an electronic device, the clutch assembly providing an overall break-away torque, the clutch assembly comprising:
A clutch assembly capable of pivotally coupling a first portion of an electronic device to a second portion of the electronic device, the clutch assembly comprising:
A method for operating a clutch assembly that pivotally couples a lid portion to a base portion of a laptop computer, the laptop computer having (i) a sensor, and (ii) the clutch assembly that includes a shaft, a first torque component providing a first break-away torque having a fixed value, and a second torque component providing a second break-away torque having a variable value, the method comprising:
