Abstract

A closure system including a curtain configured to seal an opening, a wireless network having a plurality of channels, at least one transmitter coupled to the curtain and configured to communicate over the plurality of channels, and an operator operatively coupled to the curtain and configured to communicate over the plurality of channels, the operator and the at least one transmitter configured to communicate with each other over a selected one of the plurality of channels based upon communication interference detected on one or more channels.

First claim

What is claimed is:

1. A closure system comprising:
a curtain configured to seal an opening;
a wireless network having a plurality of channels;
at least one transmitter coupled to the curtain and configured to communicate over the plurality of channels; and
an operator, the operator operatively coupled to the curtain and communicatively coupled to a receiver, and the receiver configured to communicate over the plurality of channels, the receiver and the at least one transmitter configured to communicate with each other over a selected channel of the plurality of channels based upon communication interference detected on one or more channels, wherein the receiver is configured to switch to the selected channel from a previously selected channel of the plurality of channels after a new channel detection phase detects the selected channel and the communication interference is detected on the previously selected channel.

2. The closure system of claim 1 , wherein the curtain is disposed between a first guide rail and a second guide rail.

3. The closure system of claim 1 , wherein detection of the communication interference comprises a predetermined amount of communication retries detected on the previously selected channel.

4. The closure system of claim 3 , wherein the predetermined amount of communication retries occurs consecutively within a predetermined period of time.

5. The closure system of claim 1 , wherein the receiver is configured to receive a plurality of first communication retries associated with communication interference on the previously selected channel and a plurality of second communication retries associated with communication interference on the selected channel.

6. The closure system of claim 5 , wherein the receiver is configured to compare the plurality of first communication retries on the previously selected channel with the plurality of second communication retries on the selected channel to detect the communication interference on the previously selected channel.

7. The closure system of claim 6 , wherein the receiver and the at least one transmitter determine the selected channel based on the plurality of first communication retries compared to the plurality of second communication retries.

8. The closure system of claim 5 , wherein the plurality of first communication retries occurs consecutively within a predetermined period of time.

9. The closure system of claim 1 , wherein the at least one transmitter comprises at least one sensor.

10. The closure system of claim 1 , wherein the communication interference originates from a wireless device external to the closure system.

11. The closure system of claim 1 , wherein the communication interference is a physical object disposed between the receiver and the at least one transmitter.

12. The closure system of claim 1 , wherein the communication interference is detected by the receiver.

13. The closure system of claim 1 , wherein the operator is configured to control an operation of the curtain.

14. A method of sealing an opening comprising a curtain configured to seal the opening, the curtain controlled by an operator coupled to a receiver, the receiver configured to communicate with at least one transmitter on a wireless network having at least a first channel and a second channel, the method comprising the steps of:
receiving, via the receiver, a first signal from the at least one transmitter on the first channel;
switching, via the receiver, from the first channel to the second channel when a wireless interference is detected by the operator on the first channel, wherein the switching from the first channel to the second channel comprises the steps of:
determining a number of first communication retries associated with the first channel and a number of second communication retries associated with the second channel;
comparing the number of first communication retries with the number of second communication retries; and
communicating with the at least one transmitter on the second channel if the number of first communication retries is greater than the number of second communication retries by a predetermined amount of retries;

receiving, via the receiver, a second signal from the at least one transmitter on the second channel; and
moving, via the operator, the curtain based on the second signal.

15. The method of claim 14 , wherein the predetermined amount of retries is at least five retries.

16. The method of claim 14 , wherein the number of first communication retries occurs consecutively within a predetermined period of time.
