Abstract

A control mechanism and method for a hybrid hinge for electronic devices are disclosed. A particular embodiment includes: a hybrid hinge for an electronic device, the hybrid hinge comprising: a pivot; and an auxiliary component including one or more electro-magnetic or electro-mechanical devices and a variable electrical power source, the one or more electro-magnetic or electro-mechanical devices being configured to apply a variable degree of torque force to the pivot based on a degree of electrical power supplied by the electrical power source.

a base fixture;

a lid fixture;

a pivot pivotably coupling the lid fixture and the base fixture;

one or more electro-magnetic or electro-mechanical devices to apply at least a first degree of torque force to facilitate pivoting between the lid fixture and the base fixture and to apply at least a second degree of torque force to resist pivoting between the lid fixture and the base fixture; and

a variable electrical power source to supply first power to cause the one or more electro-magnetic or electro-mechanical devices to apply the first degree of torque force when the electronic device is operating in a first mode in which a position of the lid fixture relative to the base fixture is to be changed, the variable electrical power source to supply second power to cause the one or more electro-magnetic or electro-mechanical devices to apply the second degree of torque force when the electronic device is operating in a second mode in which the position of the lid fixture relative to the base fixture is not to be changed.
