Smart variable torque display

摘要

In one example an electronic device comprises a controller, 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. Other examples may be described.

主权项

1. A controller for an electronic device, comprising logic, at least partially including hardware logic, to:
receive a torque/position profile for a hinge assembly of the electronic device; 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 an electroactive polymer (EAP) actuator coupled to a brake assembly to generate the torque corresponding to the rotational position.
