Electrically operated actuator

An electrically operated actuator in combination with a dead bolt assembly, the dead bolt assembly comprising a lock having a drive bar and a bolt, the bolt being operably coupled to the drive bar such that rotation of the drive bar extends and retracts the bolt linearly, the actuator comprising:

• means for rotating the drive bar to extend and retract the bolt;
• means for driving said rotating means, said driving means being responsive to an electrical signal;
• wherein said electrical signal is generated by a circuit comprising:
• a wireless transmitter that transmits a request to actuate the actuator;
• a wireless receiver that receives the request to actuate the actuator;
• a control circuit, operably connected to said wireless receiver, the control circuit providing said electrical signal to said driving means if the request is valid;
• and
• a plurality of sensors positioned around the driving means for sensing the status of the lock.

An electrically operated actuator for operating a lock, the lock having a bolt operably coupled to a drive bar, the actuator comprising:

• means for rotating the drive bar to extend and retract the bolt;
• means for driving said rotating means, said driving means being responsive to an electrical signal;
• wherein said electrical signal is generated by a circuit comprising:
• a transmitter for transmitting a request to actuate the actuator;
• a receiver for receiving the request to actuate the actuator;
• a control circuit, operably connected to said receiver, that generates said electrical signal to said driving means if the request is valid;
• a plurality of sensors positioned around the driving means for sensing the status of the lock;
• wherein said receiver comprises:
• a preamplifier that receives a signal and amplifies said signal to produce a preamplified signal;
• a super-regenerative, self-quenching oscillator coupled to said preamplifier for sensing said preamplified signal and producing a remaining signal;
• a gain and filtering stage coupled to said super-regenerative, self-quenching oscillator to receive said remaining signal and produce an amplified signal;
• and
• a data slicer coupled to said gain and filtering stage to receive said amplified signal and produce a received signal with logic levels.

An electrically operated actuator in combination with a dead bolt assembly, the dead bolt assembly comprising a lock having a drive bar and a bolt, the bolt being operably coupled to the drive bar such that rotation of the drive bar extends and retracts the bolt linearly, the actuator comprising:

• a drive bar attachment that is coupled to the drive bar to extend and retract the bolt linearly;
• a motor being responsive to an electrical signal;
• a gear assembly operably coupled to the motor to respond to rotation of said motor, the gear assembly being coupled to said drive bar attachment to engage said drive bar attachment to extend or retract the bolt linearly;
• wherein said electrical signal is generated by a circuit comprising:
• a wireless transmitter that transmits a request to actuate the actuator;
• a wireless receiver that receives the request to actuate the actuator;
• a control circuit operably connected to said receiver, the control circuit providing said electrical signal to said motor if the request is valid.
