Abstract

A system allows binding in a one-way wireless transmission. The system includes a transmitting wireless device having a button and a receiving wireless device having a signaling mechanism. The second wireless device receives a code transmitted from the first wireless device when the button is pressed, determines if the code has been previously received, and accepts the code if not previously received. If the code is accepted, the second wireless device signals acceptance.

Claims

1. A system, comprising:

a transmitting wireless device having a button to allow transmission of a channel access code to allow communication with the transmitting device;

a receiving wireless device having a signaling mechanism, the receiving wireless device to;

receive the channel access code transmitted from the transmitting wireless device when only the button on the transmitting wireless device is pressed;

determine if the channel access code has been previously received;

accepting the channel access code if not previously received;

signal as to a status of acceptance of the channel access code; and

use the channel access code to communicate with the transmitting device.

2. The system of claim 1, the receiving wireless device further comprising a button.

3. The system of claim 1, the transmitting wireless device further comprising a signaling mechanism.

4. The system of claim 1, the signaling mechanism further comprising one of the group comprised of:

a single LED, a pair of differently colored LEDs, an audible signaling mechanism, and a display.

5. The system of claim 1, the transmitting wireless device further comprising a wireless peripheral.

6. The system of claim 1, the receiving wireless device further comprising a wireless host.

7. A device, comprising:

a receiver;

a signaling mechanism; and

a processor to;

receive a channel access code upon a pressing of a button only on a wireless device, wherein the channel access code allows communication between the wireless device and the device;

determine if the channel access code has been previously received;

accept the channel access code if the access code had not been previously received;

activate the signaling mechanism to indicate acceptance; and

use the channel access code to communicate with the wireless device.

8. The device of claim 7, the signaling mechanism further comprising one of the group comprised of:

a single LED, a pair of differently colored LEDs, an audible signaling mechanism, and a display.

9. The device of claim 7, the device further comprising a personal computer.

10. The device of claim 7, the processor further to activate a second signaling mechanism to indicate rejection of the channel access code.

11. The device of claim 7, the device further comprising a memory having a look up table to store previously received channel access codes.

12. The device of claim 7, the device further comprising a button to allow it to initiate a binding process.

13. A method of binding a wireless device, the method comprising:

receiving a channel access code from a wireless device only when a button on the wireless device has been pressed;

determining if the channel access code has been previously received;

if the channel access code has not been previously received, accepting the channel access code;

indicating acceptance of the channel access code; and

using the channel access code to communicate with the wireless device.

14. The method of claim 13, determining if the channel access code has been previously received further comprising accessing a memory to determine if the channel access code has been previously stored.

15. The method of claim 13, indicating acceptance of the channel access code further comprising activating a signaling mechanism.

16. The method of claim 15, activating a signaling mechanism further comprising one of the group comprised of:

lighting an LED, producing an audible signal, and displaying a binding indicator on a display.

17. The method of claim 13, the method further comprising rejecting the channel access code.

18. The method of claim 17, rejecting the channel access code further comprising activating a signaling mechanism to indicate rejection.

19. The method of claim 18, activating a signaling mechanism to indicate rejection further comprising one of the group comprised of:

lighting an LED, producing an audible signal and displaying a binding indicator on a display.
