Abstract

An intelligent door lock system includes components, a drive shaft of a lock device, a processor coupled to a wireless communication device, and an energy source coupled to a circuit. A device that converts energy into mechanical energy is coupled to the circuit and the drive shaft. The device that converts energy is coupled to the energy source to receive energy from the energy source. A ramp-up speed, a steady state speed and a ramp down speed are applied to the device that converts energy into mechanical energy. The ramp-up speed is applied when a first component initially engages with a second component. The steady state speed is applied following the initial engagement and is an operational speed that the device which converts energy uses during a standard operation mode. The ramp down speed is applied as the first and second components begin a state of non-engagement.

Claims

1. A wireless access control system in communication with a first door at a dwelling and a second door at a user'"'"'s vehicle, comprising:

a user remote access device transmitting a first command signal and a command second signal;

a first intelligent door lock system, located in the first door, including;

a drive shaft of a first lock device;

a first processor coupled to a wireless communication device, the first intelligent door lock system including a sensor to determine a position of the drive shaft;

a first energy source coupled to a first circuit; and

a device that converts energy into mechanical energy coupled to the first circuit and the first drive shaft, the device that converts energy being coupled to the first energy source to receive energy from the first energy source, the first circuit providing an electrical pathway between the energy source and the first processor;

wherein the first processor is configured to cause the energy source to apply a first, a second and a third speeds to the device that converts energy into mechanical energy to provide greater control of inertia applied to the device that converts energy into mechanical energy in response to the first command signal received from the wireless communication device, the first and the thirds speeds being slower than the second speed to reduce inertia which can cause damaging to the first intelligent door lock system, to lock or unlock the first lock device, the intelligent door lock system configured to allow controlled access to the dwelling that includes an occupant of the dwelling;

a second intelligent door lock system, located at the second door, including;

a second drive shaft of a second lock device;

a second processor coupled to a second wireless communication device;

a second energy source coupled to a first circuit; and

a second device that converts second energy into mechanical energy coupled to the second circuit and the second drive shaft and the second circuit providing an electrical pathway between the second energy source and the second processor,

wherein the user remote access device configured to provide the second command signal, different from the first command signal, to a second lock device to cause the second lock device to lock or unlock; and

wherein the remote access device has a controller for generating the first and second signals.

2. The system of claim 1, wherein the second speed is a steady state speed that occurs when the energy source has an output energy that is sufficient to operate the intelligent door lock system.

3. The system of claim 2, wherein the positioning sensing device in operation is coupled to the motor that provides for moving the bolt of the lock device to at least one of a locked or unlocked positioned.

4. The system of claim 1, wherein the second speed is a steady state speed that occurs when the energy source has an output energy less than 100%.

5. The system of claim 1, wherein the second speed is a steady state that occurs when the energy source has an output energy that is at a maximum energy output sufficient to operate the intelligent door lock system.

6. The system of claim 5, wherein the maximum energy output is less than 100%.

7. The system of claim 1, wherein the second speed is a steady state speed that occurs when the intelligent door lock system is subjected to a temperature range sufficient to operate the intelligent door lock system.

8. The system of claim 1, wherein the intelligent door lock system can only operate between a minimum and a maximum temperature.

9. The intelligent door lock system of claim 8, wherein the second speed is a steady state speed that occurs when the intelligent door lock system is at the temperature from the minimum to the maximum temperature range.

10. The system of claim 1, wherein the first speed is a ramp-up speed that includes a first speed and a second speed.

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

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

13. The system of claim 1, further comprising:

a positioning sensing device.

14. The system of claim 13, wherein the position sensing device 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 position sensing device is an accelerometer.

16. The system of claim 15, 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.

17. The system of claim 15, 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.

18. The system of claim 1, wherein a lock of the intelligent door lock system can be manually locked and unlocked.

19. The system of claim 1, wherein the lock device of the intelligent door lock system can be locked or unlocked wirelessly remotely.

20. The system of claim 19, wherein the lock device can be locked or unlocked using a mobile device.
