Abstract

An intelligent door lock and remote access system includes a mobile device with a controller that transmits a first signal. A lock device has a controller and an accelerometer. In response to a receipt of the first signal the mobile device begins a process for locking and unlocking a door where the lock is located. The lock device includes a controller and an accelerator, with the accelerator acting upon processing of the first signal and in response causing a rotation of an element coupled to the accelerator to unlock the door.

Claims

1. An intelligent door lock system, comprising:

an existing door lock system at a dwelling, including;

an existing door lock system with a lock device with a lock, and a drive shaft;

an intelligent door lock system configured to be retrofitted to the existing door lock system to create a retrofitted intelligent door lock system to lock and unlock the door, the intelligent door lock system including;

a door status device configured to be coupled to the drive shaft of a lock device, the door status device determining lock or unlock status of a lock device in response to determining a position of the drive shaft;

an engine that provides power to lock and unlock the lock and coupled to the door status device, the engine coupled to at least one wireless communication device at the dwelling;

a circuit coupled to the engine, an energy source coupled to the circuit and providing power to lock or unlock the door, the energy source coupled to the circuit, the intelligent door lock system coupled with a server, wherein a user communicates with the server to grant a third party service provider limited and defined access rights to the dwelling to lock or unlock the door; and

a mobile device including a controller that transmits a first signal, the mobile device configured to be in communication with the intelligent door lock system;

wherein the mobile device includes audio circuitry, a speaker, and a microphone that provide an audio interface with the mobile device, the audio circuitry configured to receive audio data from a peripherals interface, converts the audio data to an electrical signal, and transmits the electrical signal to the speaker, the speaker configured to converts the electrical signal to human-audible sound waves, the audio circuitry configured to receive electrical signal converted by the microphone from sound waves and convert the electrical signal to audio data.

2. The system of claim 1, wherein the intelligent door lock system includes a bridge in communication with a Bluetooth device or an equivalent device.

3. The system of claim 2, wherein a signal strength between the bridge and the Bluetooth device is used to identify a person.

4. The system of claim 2, wherein the bridge is configured to provide real time conductivity to one or more servers.

5. The system of claim 2, wherein the one or more servers are at a cloud infrastructure.

6. The system of claim 2, wherein the one or more servers are at a back-end of the system.

7. The system of claim 1, wherein the system is configured to provide an identity of a person entering or exiting a dwelling.

8. The system of claim 2, wherein the Bluetooth device is any device that associates a person with a person'"'"'s identity.

9. The system of claim 2, wherein facial/body motion recognition is utilized for identification.

10. The system of claim 2, wherein the equivalent device is selected from at least one of a mobile device, a key fob and a wearable device.

11. The system of claim 1, further comprising:

using an identification of a person to determine an intent of the person entering or exiting from the dwelling.

12. The system of claim 1, wherein the system has a back-end that continuously monitors the air for identification of a person.

13. The system of claim 2, wherein the bridge uses detection of a Bluetooth device that is associated with a person to track signal strength between the bridge and the Bluetooth device to determine where the person is relative to the dwelling.

14. The system of claim 2, wherein the bridge or the mobile device determines how far the person is from a dwelling.

15. The system of claim 2, wherein the bridge tracks signal strength over time between the bridge and the Bluetooth device to determine if known or unknown people are at the exterior of the dwelling.

16. The system of claim 2, wherein the bridge tracks signal strength over time between the bridge and the Bluetooth device when to determine if the person is approaching the dwelling.

17. The system of claim 2, wherein the bridge tracks signal strength over time between the bridge and the Bluetooth device to determine if the person is entering the dwelling from the exterior.

18. The system of claim 2, wherein the bridge tracks signal strength over time between the bridge and the Bluetooth device to determine when the person enters the dwelling.

19. The system of claim 2, wherein the bridge tracks signal strength over time between the bridge and a Bluetooth device to determine if the person is moving towards the dwelling.

20. The system of claim 2, wherein the bridge tracks lock operations of an intelligent door lock system.
