Multifunctional locking device and servomotor with actuator which can be wound up around an interchangeable reel

A multifunctional locking device comprising:

• a housing;
• a servomotor in the housing;
• an actuator;
• an interchangeable reel in the housing, the reel defining a reel axis, the reel being driven about the reel axis by the servomotor;
• a sliding sheath including an end;
• a funnel-shaped combining head at the end of the sliding sheath;
• a mechanical clamp acting onto the reel and thus on the actuator,
• wherein the actuator is extensible and flexible until the actuator reaches an application point, beyond the application point the actuator becoming stiff so as to either hold steady or become a source of movement for any object or mechanism connected with the actuator, wherein inside the actuator are hidden fiber optics and a multi-core cable or single wires useful for the measurement of environmental conditions, of events, housebreaking and stop limit stress;
• and
• a circuit in the housing, the circuit being driven about the reel axis by the servomotor, the circuit being configured to receive a signal from the actuator and transmit the received signal in a wireless manner.

A multifunctional locking device comprising:

• a housing;
• a motor in the housing;
• an actuator including a distal end, a filament configured to convey a signal between the distal end and the housing, a first actuator section including a first plurality of engagement members, and a second actuator section including a second plurality of engagement members;
• a reel in the housing, the reel defining a reel axis, the reel being driven about the reel axis by the motor, the reel being configured to wind up and store the first actuator section, at a time when the first engagement members are disengaged from the second engagement members, such that the first actuator section completely encircles the reel;
• a circuit in the housing, the circuit being driven about the reel axis by the motor, the circuit being configured to receive the signal from the filament and transmit the received signal in a wireless manner;
• and
• a combining section, the combining section configured to bring the first actuator section together with the second actuator section, to engage the first plurality of engagement members with the second plurality of engagement members, thereby increasing a rigidity of the actuator and enabling the actuator to impart both a pushing force and a pulling force to an object.
