Abstract

A method, apparatus and system is disclosed for automatically opening and closing a garage door without user intervention. A vehicle-mounted mobile transmitter autonomously and continuously transmits a repeating signal pattern when power is applied to the transmitter as a vehicle is started by a user. A movable barrier gateway device receives the signals from the mobile transmitter and compares an identification code contained in each of the signals to an identification code stored in memory. When a match is found, the movable barrier gateway device sends a signal to a movable barrier controller to open the garage door, and keep the door open as long as the movable barrier gateway continues to receive the signals from the mobile transmitter.

First claim

I claim:

1 . A method, performed by a movable barrier gateway device in communication with a garage door controller, for automatically opening and closing a garage door without user intervention, comprising:
receiving a plurality of wireless signals transmitted autonomously from a mobile transmitter located on or within a vehicle when the mobile transmitter is within range of the movable barrier gateway device, each of the wireless signals comprising an identification code identifying the mobile transmitter; determining that the identification code in at least one of the wireless signals matches an identification code stored in a memory of the movable barrier gateway device; and sending a command to the movable barrier controller that causes the movable barrier controller to open the garage door when an identification code in at least one of the wireless signals matches the identification code stored in the memory.

2 . The method of claim 1 , wherein sending the command to the movable barrier controller when an identification code in at least one of the wireless signals matches the identification code stored in the memory comprises matching at least two identification codes in at least two received wireless signals.

3 . The method of claim 1 , further comprising:
after identifying at least one wireless signal that comprises an identification code matching the identification code stored in the memory, determine that no further wireless signals are being received that comprise the identification code stored in the memory; and in response to determining that no further wireless signals are being received that comprise the identification code stored in the memory, sending a second command to the movable barrier controller that causes the movable barrier controller to close the garage door.

4 . The method of claim 3 , further comprising:
determining that the garage door did not close after sending the second command to the movable barrier controller; retrieving contact information pertaining to a user of the movable barrier gateway device from the memory; generating a message indicating that the garage door failed to close; and wirelessly sending the message to the user using the contact information stored in the memory.

5 . The method of claim 1 , further comprising:
maintaining the garage door in the open position so long as the wireless signals from the mobile transmitter comprising the identification code stored in the memory continue to be received.

6 . The method of claim 1 , further comprising:
receiving input from a user of the movable barrier gateway device to perform a calibration of the movable barrier gateway device when the vehicle is located at a predetermined distance from the garage, the calibration causing the movable barrier gateway device to send the command to the movable barrier controller when the vehicle is located at the predetermined distance from the garage.

7 . The method of claim 1 , wherein the mobile transmitter autonomously and repeatedly transmits the wireless signal at a power level that limits reception of the wireless signals to a predetermined distance from the movable barrier gateway device.

8 . The method of claim 1 , wherein the plurality of wireless signals begins to be transmitted by the mobile transmitter when power is applied to the mobile transmitter as the vehicle is started.

9 . The method of claim 1 , wherein the plurality of wireless signals cease to be transmitted by the mobile transmitter when power is removed from the mobile transmitter when the vehicle is turned off.

10 . A system for automatically opening and closing a garage door without user intervention, comprising:
a mobile transmitter installed on or in a vehicle, wherein the mobile transmitter autonomously and repeatedly transmits a wireless signal comprising an identification code identifying the mobile transmitter; a movable barrier gateway device coupled to a movable barrier controller inside a garage, the movable barrier gateway device configured to receive at least one of the wireless signals transmitted autonomously and repeatedly from the mobile transmitter when the mobile transmitter is within range of the movable barrier gateway device, determine that the identification code in at least one of the wireless signals matches an identification code stored in a memory of the movable barrier gateway device, and send a command to the movable barrier controller that causes the movable barrier controller to open the garage door when an identification code in at least one of the wireless signals matches the identification code stored in the memory.

11 . The system of claim 10 , wherein sending the command to the movable barrier controller when an identification code in at least one of the wireless signals matches the identification code stored in the memory comprises matching at least two identification codes in at least two received wireless signals.

12 . The system of claim 10 , wherein the movable barrier gateway device is further configured to:
after identifying at least one wireless signal that comprises an identification code matching the identification code stored in the memory, determine that no further wireless signals are being received that comprise the identification code stored in the memory, and in response to determining that no further wireless signals are being received that comprise the identification code stored in the memory, send a second command to the movable barrier controller that causes the movable barrier controller to close the garage door.

13 . The system of claim 12 , wherein the movable barrier gateway device is further configured to:
determine that the garage door did not close after sending the second command to the movable barrier controller; retrieve contact information pertaining to a user of the system from the memory; generate a message indicating that the garage door failed to close; and wirelessly send the message to the user using the contact information stored in the memory.

14 . The system of claim 10 , wherein the movable barrier gateway device is further configured to maintain the garage door in the open position so long as the wireless signals from the mobile transmitter comprising the identification code stored in the memory continue to be received.

15 . The system of claim 10 , wherein the movable barrier gateway device is further configured to:
receive input from a user of the system to perform a calibration of the movable barrier gateway device when the vehicle is located at a predetermined distance from the garage, the calibration causing the movable barrier gateway device to send the command to the movable barrier controller when the vehicle is located at the predetermined distance from the garage.

16 . The system of claim 10 , wherein the mobile transmitter autonomously and repeatedly transmits the wireless signal at a power level that limits reception of the wireless signals to a predetermined distance from the movable barrier gateway device.

17 . The system of claim 10 , wherein the mobile transmitter is configured to begin transmitting the wireless signals when power is applied to the mobile transmitter as the vehicle is started.

18 . The system of claim 10 , wherein the mobile transmitter is configured to cease transmitting the wireless signals when power is removed from the mobile transmitter as the vehicle is turned off.
