Abstract: A cutting length adjustment mechanism for a hair cutting appliance, a hair cutting appliance, a method of operating a cutting length adjustment mechanism for a hair cutting appliance and an adjustment drive for a cutting length adjustment mechanism for a hair cutting appliance wherein the adjustment drive includes an actuator that is configured to actuate a movable portion of the cutting length adjustment mechanism with respect to a housing portion of the hair cutting appliance, and a movement sensor unit that is configured to detect a movement of the hair cutting appliance, the movement involving at least one of an orientation change and a position change. The actuator is further configured to output an adjustment control signal that is derived from the detected movement. In a length adjustment mode, the actuator is operated on the basis of the adjustment control signal.

Abstract: The present disclosure relates to an adjustment drive (50; 150) for a cutting length adjustment mechanism (24; 130) for a hair cutting appliance (10; 110), the adjustment drive (50; 150) comprising an actuator (52) that is configured to actuate a movable portion (40; 120) of the cutting length adjustment mechanism (24; 130) with respect to a housing portion (12; 112) of the hair cutting appliance (10; 110), and a movement sensor unit (66) that is configured to detect a movement of the hair cutting appliance (10; 110), involving at least one of an orientation change and a position change, and to output an adjustment control signal that is derived from the detected movement, wherein, in a length adjustment mode, the actuator (52) is operated on the basis of the adjustment control signal.

Abstract: An adjustment drive is provided for an adjustable spacing comb for a hair cutting appliance. The adjustment drive includes an actuator, a sensor element and a control unit. The actuator actuates a movable comb portion of the adjustable spacing comb with respect to a blade set of the hair cutting appliance. The sensor element detects multi-faceted user inputs applied to the sensor element by a user and to output a user input signal that is derived from the multi-faceted user inputs. The actuator is operated on the basis of the user input signal. The control unit is coupled to the actuator and to the sensor element, and converts the user input signal into an actuator operating signal. The multi-faceted user inputs include detected user input speed of an input stroke by the user.

Abstract: The present disclosure relates to an adjustment drive (50) for an adjustable spacing comb (26) for a hair cutting appliance (10) and to a hair cutting appliance (10) that is fitted with an adjustable spacing comb (26). The present disclosure further relates to a method for operating an adjustable spacing comb (26) for a hair cutting appliance (10). The adjustment drive (50) comprises an actuator (52) that is configured for actuating a movable comb portion (40) of the adjustable spacing comb (26) with respect to a blade set (16) of the hair cutting appliance (10), and a proximity sensitive or touch sensitive sensor element (64), particularly a gesture control user input interface, wherein the sensor element (64) is configured to detect multi-faceted user inputs (70, 72) applied to the sensor element (64) and to output a user input signal that is derived from the multi-faceted user inputs (70, 72), and wherein the actuator (52) is operated on the basis of the user input signal.
