Abstract: An apparatus with rotor input detection includes: a first reactance element disposed at a rotor configured such that at least a part of the rotor rotates around a rotation axis, and disposed at the rotor such that reactance of the first reactance element varies depending on relative rotation between a first portion of the rotor and a second portion of the rotor; and a second reactance element disposed at the rotor such that reactance of the second reactance element varies depending on a contact or a force applied to a side surface of the rotor. The first and second reactance elements are configured to detect inputs of different areas of the rotor.

Abstract: An apparatus for sensing a rotating body includes a rotating body including a detection target portion; a pattern portion disposed in the detection target portion in a direction in which the rotating body rotates; a frame that rotatably supports the rotating body; a first sensor disposed to oppose a first region of the detection target portion; a second sensor spaced apart from the first sensor and disposed to oppose a second region of the detection target portion; and a holder portion coupled to the frame to hold the first sensor and the second sensor.

Abstract: A rotating device sensing apparatus includes: a rotating device comprising a detection target unit; a pattern portion formed in the detection target unit in a direction of rotation of the rotating device; a first sensor disposed to face one region of the detection target unit; and a second sensor, spaced apart from the first sensor, and disposed to face another region of the detection target unit, wherein the pattern portion comprises a first pattern portion and a second pattern portion having different widths.

Abstract: An apparatus for processing rotor movement information includes a processor configured to: receive movement information of a rotor disposed on one surface of an electronic device and having a rotation axis formed in a direction of the electronic device; receive touch information of a sensor configured to sense a touch on another surface of the electronic device; and produce operating information of the electronic device based on the movement information of the rotor. The operating information of the electronic device has variable correlation of the operating information to the movement information, in accordance with the touch information.

Abstract: A channel searching method may include setting a first channel in a broadcast signal, determining signal strength of the broadcast signal and generating an automatic gain control signal for the first channel, and when the signal strength satisfies a preset first requirement and the automatic gain control signal satisfies a preset second requirement, skipping demodulation of the first channel.
