Abstract

Disclosed is one or more monitoring systems and methods for monitoring opening events for a door of an enclosure. Disclosed is a sensor device configured to be specifically calibrated to sense when the door is at a predetermined open position relative to the enclosure, the sensor device providing sensor output and a telemetry output system configured to transmit the sensor output. Also disclosed is sensor device that may include an arm wherein when the door opens, wherein the arm slides against the door resulting in a switch event when the door is opened to the predetermined open position relative to the enclosure, the switch event resulting in sensor output. The present disclosure further relates to making predictions of the number of units within an enclosure based upon data gathered by one or more suitable sensors.

Claims

1. An electro-mechanical adjustable monitoring system configured to monitor door opening events of a door connection system, the system being configured to allow a door to open to a predetermined open position relative to the enclosure wherein the door is capable of being opened to a more fully opened position beyond the predetermined open position, the monitoring system comprising:

at least one sensor device configured to be adjustably calibrated when the sensor device is installed on the enclosure proximal to the door to sense when the door is at the predetermined open position relative to the enclosure the predetermined open position adjustably specifically calibrated by the sensor as a position of the door between a closed position and the more fully opened position beyond the predetermined open position, so that the sensor device is configured to detect when the door has been opened to at least the predetermined open position relative to the enclosure based upon the adjustable calibration mechanically set when the device is installed proximal to the door, the sensor device providing sensor output.

2. The monitoring system as claimed in claim 1, further comprising a telemetry output system configured to transmit the sensor output.

3. The monitoring system as claimed in claim 1, wherein the sensor output provides at least one of a count of when the door has been opened to at least the predetermined open position relative to the enclosure and a time stamp of when the door has been opened to at least the predetermined open position relative to the enclosure.

4. The monitoring system as claimed in claim 1, wherein the sensor output is provided at predetermined time intervals.

5. The monitoring system as claimed in claim 1, wherein the sensor device comprises an arm such that when the door opens, the arm slides against the door resulting in a switch event when the door is opened to the predetermined open position relative to the enclosure, the switch event resulting in sensor output.

6. The monitoring system as claimed in claim 5, wherein the sensor device is configured to be calibrated during installation proximal to the enclosure by fixing the arm in a position relative to the enclosure.

7. The monitoring system as claimed in claim 1, wherein the sensor device provides image sensor output.

8. The monitoring system as claimed in claim 1, wherein the sensor device is configured to be calibrated during installation proximal to the enclosure.

9. The monitoring system as claimed in claim 8, wherein the sensor device comprises an arm and at least one housing member wherein during installation, the arm and the housing member are loosely bound prior to calibration, and then tightly bound upon calibration.

10. A method to automatically audit the number of units within an enclosure having at least one door, comprising:

receiving from a remote telemetry device data indicating the number of times within a predetermined period of time a door has been opened to a predetermined open position relative to the enclosure, the predetermined open position of the door being specifically calibrated by a sensor device being mechanically set when the sensor device is installed on the enclosure proximal to the door as a position of the door between a closed position and a more fully opened position beyond the predetermined open position, to generate a door opening count, wherein the remote telemetry device includes a sensor configured to be adjustably calibrated to sense when the door is at the predetermined open position relative to the enclosure based upon the adjustable calibration, to generate the door opening count.

11. The method as claimed in claim 10, further comprising:

receiving a number of the units positioned with the enclosure at a prior particular time; and

determining a current count of the units based on the data indicating the number of times within a predetermined period of time a door has been opened to a predetermined open position relative to the enclosure and the number of units positioned within the enclosure at a prior particular time.

12. The method as claimed in claim 11, further comprising:

applying an historical correlation factor to the current count to generate a prediction of when the units in the enclosure will reach a predetermined inventory.

13. The method as claimed in claim 11, further comprising:

applying a characteristic correlation factor to the current count to generate a prediction of when the units in the enclosure will reach a predetermined inventory number.

14. The monitoring system as claimed in claim 10, wherein the remote telemetry device comprises an arm such that when the door opens, the arm slides against the door resulting in a switch event when the door is opened to the predetermined open position relative to the enclosure, the switch event resulting in sensor output.

15. A remote telemetry device for automatically auditing the number of items within an enclosure having at least one door for removal and restocking of the items, comprising:

a remote telemetry device in communication with at least one sensor device configured to be calibrated, the calibration of the sensor device being set when the sensor device is installed based upon the size of an item, the sensor configured to detect the door opening to a calibrated door open position, data indicative of the number of items within the enclosure to determine a current count.

16. The device as claimed in claim 15, wherein the device is mechanically set during installation.

17. The device as claimed in claim 15, further comprising applying a historical correlation factor to correct the current count to generate a prediction of when the items in the enclosure will reach a predetermined inventory.

18. The device as claimed in claim 15, further comprising:

applying a characteristic correlation factor to the current count to generate a prediction of when the items in the enclosure will reach a predetermined inventory number.

19. The device as claimed in claim 15 wherein the item is a gas cylinder.

20. The remote telemetry device as claimed in claim 15, further comprising an arm such that when the door opens, the arm slides against the door resulting in a switch event when the door is opened to predetermined open position relative to the enclosure, the switch event resulting in sensor output.
