Controllable apparatus and control handle for producing such controllable apparatus

Controllable device comprising:

• a control handle comprising:
• a plurality of detection zones Zi arranged at locations on the handle which allow detection of a correct grip of the handle by a pilot's hand, where the index i is an identifier of the detection zone Zi, each of these detection zones Zi being equipped for this purpose with at least one sensor capable of reversibly switching between:
• an active state in which it detects the presence of the pilot's hand on the detection zone Zi, and alternately
• an idle state in which the presence of the pilot's hand on the detection zone Zi is not detected,
• each sensor in zone Zi being insensitive to the presence and absence of the pilot's hand in a detection zone other than detection zone Zi,
• an actuator actuated in response to receipt of a control command,
• a processing unit configured:
• to trigger the indication of a correct grip of the handle, depending on the state of the control handle sensors,
• in response to an absence of the indication of a correct grip of the control handle, to switch the handle to a deactivated state in which the sending of the control command to the actuator, in response to a movement of the handle or in response to the actuation of a button on the handle, is systematically inhibited and, alternately,
• in response to an indication of the correct grip of the control handle, to switch the handle to an activated state in which, in response to a movement of the handle or in response to actuation of the button on the handle, the control command is sent to the actuator,
• wherein:
• each detection zone Zi comprises a first and a second of the sensors each able to switch to its active state when it detects the presence on the detection zone Zi of the pilot's hand, these first and second sensors of the detection zone Zi being sensitive to, respectively, a first and a second physical characteristic of the pilot's hand in order to detect the presence and, alternatively, the absence of the pilot's hand on the detection zone Zi, the second physical characteristic being independent of the first physical characteristic so that the second sensor is able to detect the presence of the hand on the detection zone Zi in a particular context of use where the first sensor is unable to do so, and
• the processing unit is configured:
• to calculate the number of detection zones Zi which include at least one sensor in its active state and then to check whether this calculated number is greater than a predetermined threshold, this predetermined threshold being greater than one, and
• when this calculated number is greater than this predetermined threshold, to trigger the indication of the correct grip of the handle.
