Disclosed is a controlling method for an unmanned aerial vehicle (UAV) that includes an image device. The controlling method includes transmitting, by a remote controller when a dial of a dial structure of the remote controller is rotated, a first control signal for changing imaging device information of an imaging device of the UAV via a signal transmitting device of the remote controller. The imaging device information comprises at least one of an operating mode of the imaging device, a shutter speed of the imaging device, an aperture size of the imaging device, a light sensitivity of the imaging device, or a preview image of the imaging device. The controlling method further includes transmitting a second control signal for confirming imaging device information via the signal transmitting device by the controller when the dial is slid with a displacement,?

An input assembly for inputting a control command for an operator control apparatus is provided, comprising a pushbutton head manually displaceable along a longitudinal axis and a movable signal transmitter which is coupled to the pushbutton head via a coupling mechanism. The input assembly comprises at least one latch element having a latch head which has associated therewith at least one latch depression which the latch head enters when the pushbutton head has reached a predetermined stroke position. The at least one latch element has associated therewith a travel groove oriented parallel to the longitudinal axis, which travel groove the latch head of the latch element enters permanently. The at least one latch depression associated with the latch element is arranged in the travel groove. An operator control apparatus having such an input assembly is also provided.

Exemplary embodiments provides a camera, having a first camera sub-assembly, a hub coupled to the first camera sub-assembly, a second camera sub-assembly coupled to the hub and rotatable relative thereto and a third camera sub-assembly coupled to the hub and rotatable relative thereto. The third camera sub-assembly can be in electrical communication with the first camera sub-assembly and/or the second camera sub-assembly via the hub. The hub can include a slot to guide electrical cable(s). Net torque acting on the camera can be zero such that one of the first rotational coupling or the second rotational coupling when rotated to a new position via an applied torque remains in the new position when the applied torque is released.

A rotational operation device that is capable of setting an operation mode corresponding to a user's intention even when rotation of a rotational operation member stops on the way during a rotational operation. A rotational operation member is rotatable around a rotation axis. A click force application mechanism applies click force to the rotational operation member according to its rotational operation. A detection unit detects rotation of the rotational operation member. A setting unit sets one operation mode from among a plurality of predetermined operation modes in response to a detection output of the detection unit. The setting unit switches the operation mode according to a rotational operation of the rotational operation member before a position where the click force applied to the rotational operation member by the click force application mechanism becomes zero in a case where the rotational operation member is rotated in a first direction.

Example control devices for operating bicycle components are described herein. An example control device includes a housing having an opening to receive a handlebar of the bicycle and a rotating member rotatably coupled to the housing. The rotating member is rotatable about a first axis. The rotating member is configured to rotate between a first position and a second position to change an operating state of a component. The example control device includes a securing mechanism configured to lock the rotating member in the second position. The example control device also includes a release actuator coupled to the housing. The release actuator has an actuating surface to be engaged by a user and moved along a second axis that intersects the first axis. The release actuator is configured to, when actuated, unlock the securing mechanism to enable the rotating member to rotate back to the first position.

A dial structure, a remote controller employing the dial structure, and a controlling method are provided. The dial structure comprises a carrying member and a dial movably connected with the carrying member. The dial is slidable with respect to the dial structure along a sliding direction and rotatable around a rotation shaft. An axial direction of the rotation shaft intersects with the sliding direction. The dial structure further comprises a rotation sensor configured to obtain rotating state information of the dial and a sliding sensor configured to obtain sliding state information of the dial.
