Method for utilizing a wireless connection to unlock an opening
First Claim
1. A method of operating a lock from a portable remote device, the lock controlling access to an area secured by a physical barrier, comprising:
- sending a radio frequency identification signal from the portable remote device to a controller for the lock;
receiving the radio frequency identification signal at the lock controller and identifying the remote device as an authorized user of the lock;
sending a sound frequency identification signal from the portable remote device to the lock controller;
receiving the sound frequency identification signal from the portable remote device at the lock controller;
determining a side of the barrier from which the sound frequency identification signal is sent from the portable remote device;
identifying the portable remote device as an authorized user of the lock; and
authorizing operation of the lock in accordance with the radio or sound frequency identification signal from the portable remote device and only if the sound frequency identification signal is sent from the portable remote device from a desired side of the barrier.

Abstract
A method of operating a lock from a portable remote device includes sending a radio frequency identification signal from the portable remote device to a controller for the lock, and receiving the radio frequency identification signal at the lock controller and identifying the remote device as an authorized user of the lock. The method then includes sending a sound frequency identification signal from the portable remote device to the lock controller, receiving the sound frequency identification signal at the lock controller and identifying the remote device as an authorized user of the lock. The method further includes authorizing operation of the lock in accordance with the radio or sound frequency identification signal from the portable remote device. A system for practicing the method includes a lock controller capable of receiving a radio frequency identification signal and a sound frequency identification signal from the portable remote device.

14. A lock controller for operating a lock for a door from a portable remote device comprising:
-
an antenna for receiving a radio frequency identification signal; a microphone for receiving a sound frequency identification signal from the portable remote device; a microprocessor for processing a radio frequency identification signal received by the antenna and a sound frequency identification signal received by the microphone to determine whether the radio frequency identification signal and the sound frequency identification signal identify the remote device as an authorized user of the lock; and a device driver controllable by the microprocessor for operating the lock upon determination by the lock controller that the radio frequency identification signal and the sound frequency identification signal identify the remote device as an authorized user of the lock, the lock controller capable of and adapted to receive a radio frequency identification signal, use the microprocessor to determine whether the remote device is an authorized user of the lock and, if the remote device is identified as an authorized user of the lock, send a radio frequency signal from the lock controller to the remote device specifying a frequency, duration and/or amplitude of the sound frequency identification signal to be sent from the portable remote device; the lock controller further capable of and adapted to receive the sound frequency identification signal from the portable remote device and use the microprocessor to determine whether the remote device is an authorized user of the lock and, if the remote device is identified as an authorized user of the lock from both the radio frequency identification signal and the specified frequency, duration and/or amplitude of the sound frequency identification signal, send an authorization signal from the processor to the device driver authorizing unlocking of the lock. - View Dependent Claims (15, 16, 17, 18)

19. A lock controller for operating a lock for a door from a portable remote device, the lock controlling access to an area secured by a physical barrier, comprising:
-
an antenna for receiving a radio frequency identification signal; a microphone on each side of the barrier for receiving a sound frequency identification signal from the portable remote device; a microprocessor for processing a radio frequency identification signal received by the antenna and a sound frequency identification signal received by the microphone to determine whether the radio frequency identification signal and the sound frequency identification signal identify the remote device as an authorized user of the lock; and a device driver controllable by the microprocessor for operating the lock upon determination by the lock controller that the radio frequency identification signal and the sound frequency identification signal identify the remote device as an authorized user of the lock, the lock controller capable of and adapted to receive a radio frequency identification signal, use the microprocessor to determine whether the remote device is an authorized user of the lock and, if the remote device is identified as an authorized user of the lock, send a radio frequency signal from the lock controller to the remote device specifying the sound frequency identification signal to be sent from the portable remote device; the lock controller further capable of and adapted to receive the sound frequency identification signal from the portable remote device and use the microprocessor to determine a side of the barrier from which the sound frequency identification signal is sent from the portable remote device and whether the remote device is an authorized user of the lock, and, if the portable remote device is identified as an authorized user of the lock from both the radio frequency identification signal and the sound frequency identification signal and if the sound frequency identification signal is sent from the portable remote device from a desired side of the barrier, send an authorization signal from the processor to the device driver authorizing unlocking of the lock.
