Zusammenfassung:Techniques for ultrasound-based hinge estimation are disclosed. In the illustrative embodiment, a speaker in a base portion of a computing device generates an ultrasonic sound pulse. The pulse is sensed by a microphone in a lid portion of the computing device. The time-of-flight of the sound pulse from the speaker to the microphone is used to determine the distance between the speaker and the microphone. The angle of the lid portion relative to the microphone portion can then be determined based on the position of the speaker, the position of the microphone, and the distance between the speaker and the microphone
