Passive garage door operator system
First Claim
1. A wireless transmitter system for activating from a vehicle a device associated with the security of a dwelling while the vehicle is remote from the dwelling, the system comprising:
- a magnetic field sensor for detecting a magnet having a flux density in the path of the vehicle when it is proximate to the dwelling; and
a transmitter responsive to the detection of said flux density for sending a coded security signal that activates the device without intervention by an occupant of the vehicle.

Abstract
A passive remote garage door operator system including a magnetic field sensor which detects a magnet having a flux density and a transmitter that sends a coded security signal to activate a garage door. A controller determines whether the magnet field sensor detects the magnet from a first direction or a second direction and activates the position of the garage door. The magnetic field sensor is preferably affixed to the underside of a vehicle and the magnets are embedded in a driveway leading to the garage. The system thereby automatically opens a garage door based upon the approach of a vehicle and closes automatically based upon the exit of the vehicle without any intervention by the human vehicle operator.

10. A garage door operator system for operating a garage door of a dwelling from a vehicle, the system comprising:
-
a first magnet for mounting remote from the dwelling and having a first flux density; a first magnetic field sensor for mounting on the vehicle to detect said first flux density; and a transmitter for mounting on the vehicle to send a garage door activation signal in response to detection of said first flux density by said first magnetic field sensor without active intervention by an occupant of the vehicle. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method of transmitting a signal from a vehicle to a device associated with the security of a dwelling while the vehicle is remote from the dwelling, the method comprising the steps of:
-
(a) providing a vehicle having a magnetic field sensor mounted thereon; (b) passing the vehicle proximate to a magnet having a flux density to detect said flux density by said magnetic field sensor; and (c) transmitting a coded security signal in response to the detection of said flux density to activate the device without intervention by an occupant of the vehicle. - View Dependent Claims (19, 20, 23, 24)
