Abstract

An intelligent door lock system includes a position sensing device configured to be coupled to a drive shaft of a lock device. The position sensing device senses position of the drive shaft to assist in locking and unlocking a lock of a lock device. A processor is coupled to a wireless communication module that utilizes audio and RF communication to communicate. Audio is used to communicate a security key to the wireless communication device and the RF increases a wireless communication range to and from the wireless communication device. A circuit is coupled to the engine and to an energy source. A device converts energy into mechanical energy and is coupled to the circuit, positioning sensing device and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source.

First claim

The invention claimed is:

1. An intelligent door lock system at a dwelling, comprising:
a position sensor configured to be coupled to a drive shaft of a lock system, the position sensor sensing position of the drive shaft to assist in locking and unlocking a lock of the lock system, the position sensor configured to know its current position even if it has been moved since it has been turned off;
a processor coupled to a wireless communication apparatus that utilizes audio and RF communication;
a circuit coupled to an engine;
an energy source coupled to the circuit;
an apparatus that converts energy from an energy source into mechanical energy coupled to the circuit, position sensor and the drive shaft, the apparatus that converts energy being coupled to the energy source to receive energy from the energy source, and
wherein a mobile device at an interior or exterior of the dwelling is configured to provide locking or unlocking of the lock, the intelligent door lock system configured to allow controlled access to the dwelling that includes an occupant of the dwelling as well as a designated third person granted access rights by the occupant.

2. The system of claim 1 , wherein the system includes first and second wireless communication apparatus, wherein the first wireless communication apparatus communicates audio and the second wireless apparatus communication communicates RF.

3. The system of claim 1 , wherein the lock is included in the intelligent door lock system.

4. The system of claim 1 , wherein audio communications initial set up information is from a mobile device or a key fob to the intelligent door lock system.

5. The system of claim 4 , wherein an initial set up information includes at least one of, SSID WiFi, password WiFi, a Bluetooth key, a security key and door configurations.

6. The system of claim 1 , wherein the apparatus that converts energy is coupled through the circuit to the energy source.

7. The system of claim 1 , wherein the intelligent door lock system is installed to an existing lock system already mounted at a door.

8. The system of claim 1 , wherein the intelligent door lock system is installed at a door without a pre-existing lock system.

9. The system of claim 1 , wherein the position sensor is an accelerometer.

10. The system of claim 9 , wherein the accelerometer determines position of the drive shaft and at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

11. The system of claim 9 , wherein accelerometer does not require additional power than that required for determining the at least one of, door knocking, picking of the lock, break-in and unauthorized entry, door open and closing motion.

12. The system of claim 1 , wherein the position sensor in operation is coupled to the apparatus that converts energy that provides for moving a bolt of the lock device to at least one of a locked or unlocked positioned.

13. The system of claim 1 , wherein the lock can be manually locked and unlocked.

14. The system of claim 1 , wherein the position sensor is selected from at least one of, an accelerometer, optical encoder, magnetic encoder, mechanical encoder, Hall Effect sensor, potentiometers, contacts with ticks and an optical camera encoders.

15. The system of claim 1 , wherein the lock system can be locked or unlocked from a server in a cloud system in communication with the intelligent door lock system.

16. The system of claim 1 , wherein the circuit is coupled to at least one of, the processor, the power source, the position sensor, a speaker, a temperature sensor, a battery, voltage sensor, a current sensor that determines how hard the apparatus that converts energy is working, a protection circuit to protect the apparatus that converts energy from overheating and an LED array.

17. The system of claim 1 , further comprising:
wing latches coupled to a chassis of the intelligent door lock system.

18. The system of claim 17 , wherein the wing latches attach to a mounting plate of the door.

19. The system of claim 1 , further comprising:
an intelligent door lock system cloud based server in wireless communication with the intelligent door lock system.

20. The system of claim 1 , wherein the position sensor is positioned on the drive shaft.

21. The system of claim 9 , wherein the accelerometer provides at least one of, a number of times a door is closed or opened, a degree of door physical swing, of the door, and distance of door swing.

22. The system of claim 21 , wherein tile accelerometer in operation provides a determination as to whether or not someone successfully swung the door.
