Abstract

A system, method and apparatus for monitoring a barrier. The barrier sensor refrains from transmitting an alarm signal to a receiver when the barrier sensor determines that the barrier has been placed into an open position and that a human being is inside the premises in proximity to the human detection device. Further, the barrier sensor transmits an alarm signal to a receiver when the barrier sensor determines that the barrier has been moved from the open position and that a human being is not inside the premises in proximity to the barrier.

First claim

I claim:

1 . A barrier sensor coupled to a barrier, comprising:
a barrier status detection device for detecting when the barrier moves from a closed position into an opened position; an infrared or ultrasonic human detection device for determining when a human being is inside a monitored premises in proximity to the barrier; a transmitter for transmitting an alarm signal to a receiver; a memory having processor-executable instructions stored thereon; and a processor coupled to the human detection device, the barrier status detection device, the transmitter and the memory, the processor for executing the processor-executable instructions that causes the barrier sensor to: determine, via use of the human detection device, that a human being is inside the premises in proximity to the barrier sensor; and in response to determining that the human being is inside the premises in proximity to the barrier sensor, cause the barrier sensor to ignore signals from the barrier status detection device or refrain from transmitting an alarm signal via use of the transmitter.

2 . The barrier sensor of claim 1 , wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to:
determine that the human being is no longer in proximity to the barrier; and in response to determining that the human being is no longer in proximity to the barrier, re-enable the barrier sensor.

3 . The barrier sensor of claim 1 , further comprising:
a movement detector coupled to the processor for detecting when the barrier has been moved from an open position; wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to: determine, based on one or more electronic signals from the movement detector, that the barrier has been placed into the open position; determine, based on one or more other electronic signals from the movement detector, that the barrier has been moved from the open position; and in response to determining that the barrier has been moved from the open position, transmit an alarm signal to a receiver.

4 . The barrier sensor of claim 1 , further comprising:
a barrier status detection device coupled to the processor for detecting when the barrier has been opened; and a movement detector coupled to the processor for detecting when the barrier has been moved from an open position; wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to: determine, based on one or more electronic signals from the barrier status detection device, that the barrier has been placed into the open position; determine, based on one or more other electronic signals from the movement detector, that the barrier has been moved from the open position; and in response to determining that the barrier has been moved from the open position, transmit an alarm signal to a receiver.

5 . The barrier sensor of claim 1 , further comprising:
a movement detector coupled to the processor for detecting when the barrier has been moved from an open position; wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to: monitor the barrier status detection device until the barrier has been opened; and after detecting that the barrier has been opened, begin to monitor the movement detector to determine when the barrier has been moved from the open position.

6 . The barrier sensor of claim 1 , further comprising:
a movement detector coupled to the processor for detecting when the barrier has been moved from an open position; wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to: monitor the barrier status detection device until the barrier has been opened; after detecting that the barrier has been opened, begin to monitor the movement detector to determine when the barrier has been moved from the open position; and after beginning monitoring of the movement detector, stop monitoring the barrier status detection device.

7 . The barrier sensor of claim 6 , wherein the processor-executable instructions comprise further instructions that causes the barrier sensor to:
determine that the barrier has been closed after determining that the barrier was in the open position; and in response to determining that the barrier has been closed, begin to monitor the barrier status detection device to determine when the barrier has been re-opened.

8 . A method performed by a barrier sensor coupled to a barrier comprised of a barrier status detection device for detecting when the barrier moves from a closed position into an opened position, an infrared or ultrasonic human detection device for determining when a human being is inside a monitored premises in proximity to the barrier, and a transmitter for transmitting an alarm signal to a receiver, comprising:
determining, via use of the human detection device, that a human being is inside the premises in proximity to the barrier sensor; and in response to determining that the human being is inside the premises in proximity to the barrier sensor, causing the barrier sensor to ignore signals from the barrier status detection device or refrain from transmitting an alarm signal via use of the transmitter.

9 . The method of claim 8 , further comprising:
determining that the human being is no longer in proximity to the barrier; and in response to determining that the human being is no longer in proximity to the barrier, re-enabling the barrier sensor.

10 . The method of claim 8 , further comprising:
determining that the barrier has been placed into an open position; determining that the barrier has been moved from the open position; and in response to determining that the barrier has been moved from the open position, transmitting an alarm signal to a receiver.

11 . The method of claim 8 , further comprising:
determining that the barrier has been placed into an open position; determining that the barrier has been moved from the open position; and in response to determining that the barrier has been moved from the open position, transmitting an alarm signal to a receiver.

12 . The method of claim 8 , further comprising:
monitoring the barrier status detection device of the barrier sensor until the barrier has been opened; and after detecting that the barrier has been opened, begin monitoring a movement detector of the barrier sensor to determine when the barrier has been moved from the open position.

13 . The method of claim 8 , further comprising:
monitoring the barrier status detection device of the barrier sensor until the barrier has been opened; after detecting that the barrier has been opened, begin monitoring a movement detector of the barrier sensor to determine when the barrier has been moved from the open position; and after beginning monitoring of the movement detector, stop monitoring the barrier status detection device.

14 . The method of claim 13 , further comprising:
determining that the barrier has been closed after determining that the barrier was in the open position; and in response to determining that the barrier has been closed, begin monitoring the barrier status detection device to determine when the barrier has been re-opened.
