An electronic device comprises a rotational operation member and a control unit that controls an angle of rotation at which to generate a clicking sensation in the rotational operation member. The control unit controls the angle of rotation based on a division of a setting to be changed in accordance with a rotational operation of the rotational operation member.

In an embodiment a magnetorheological fluid-based haptic knob apparatus includes a housing, a solenoid coil mounted inside the housing, the solenoid coil configured to generate a magnetic field thereby providing magnetic flux, a shaft connected to the housing and including a rotational rod, wherein the shaft is configured to generate a plurality of modes and a magnetorheological fluid accommodated inside the housing, the magnetorheological fluid configured to form a magnetic chain in response of the magnetic flux.

A system for a two-step activation for a valve includes at least one valve control selector having an output representative of a valve position and a touch sensor having an output representative of a permission to operate said valve.

A vehicle function control apparatus and method control various vehicle functions. A control method of an integrated manipulation unit may include: establishing a first data path with a first detachable knob attached to a first attachment position among at least one attachment position provided in an attachment unit; transmitting information on a first function to be controlled corresponding to the first attachment position to the first detachable knob through the first data path; establishing a second data path with a second detachable knob stacked on the first detachable knob; and transmitting information on a second function to be controlled corresponding to the first attachment position to the second detachable knob through the second data path.

A hair appliance includes a handle, an electrical component coupled with the handle, and a switch mechanism in electrical communication with the electrical component and a power source. The electrical component has a plurality of settings. The switch mechanism includes a switch and a rotatable adjustment member. The switch has multiple positions and includes a sliding actuator. Each position corresponds to a respective setting for the electrical component. The rotatable adjustment member includes a contact surface operatively coupled with the sliding actuator such that rotational movement of the rotational adjustment member results in translational movement of the sliding actuator.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.
