Abstract: A wireless power transmitter includes a sampling controller setting different retrieval sampling points of time for each section, among candidate sampling points of time, in each section of a carrier frequency signal; and a sampling unit configured to sample points of the carrier frequency signal at the different retrieval sampling points of time. The sampling controller compares values sampled by the sampling unit with each other, and determines a determined sampling point based on a comparison result.

Abstract: An actuator includes an oscillating unit including two or more oscillation circuits each configured to output an oscillation signal including a frequency, which is changed in response to movement of a detection target, a frequency down-converting unit configured to down-convert frequencies of two or more oscillation signals respectively output from the two or more oscillation circuits, and a determining unit configured to calculate a position of the detection target in response to two or more down-converted oscillation signals output from the frequency down-converting unit.

Abstract: An actuator including a detection target disposed on a surface of a lens barrel, and a position detecting unit including two or more sensing coils and configured to detect a displacement of the detection target in a first direction perpendicular to an optical axis, wherein when the detection target moves in a second direction perpendicular to the optical axis, an area of overlap between each of the two or more sensing coils and the detection target is maintained constant.
