Smart variable torque display

An electronic device, comprising:

• a chassis comprising a first section and a second section;
• and
• a hinge assembly to connect the first section of the chassis to the second section of the chassis, comprising:
• a shaft rotatable about a first axis;
• a brake selectively engageable with a portion of the shaft;
• and
• an electroactive polymer (EAP) actuator coupled to the brake, wherein the EAP actuator selectively engages the brake with a portion of the shaft in response to a signal from the controller;
• and
• a controller comprising logic, at least partially including hardware logic, to:
• receive a torque/position profile for the hinge assembly;
• store the torque/position profile in a memory communicatively coupled to the controller;
• receive a rotational position of the hinge assembly;
• receive torque information for the hinge assembly;
• determine, from the torque/position profile, a torque corresponding to the rotational position;
• and
• selectively actuate the electroactive polymer (EAP) actuator coupled to a brake assembly to generate the torque corresponding to the rotational position.

A method to manage a torque for a hinge on an electronic device, comprising:

• receiving, in a controller of the electronic device, a torque/position profile for a hinge assembly of the electronic device;
• storing the torque/position profile in a memory communicatively coupled to the controller;
• receiving, in the controller, a rotational position of the hinge assembly;
• receiving, in the controller, torque information for the hinge assembly;
• determining, from the torque/position profile, a torque corresponding to the rotational position;
• and
• selectively actuating an electroactive polymer (EAP) actuator coupled to a brake assembly to generate the torque corresponding to the rotational position.
