Abstract

A first wireless control device may be associated with a second wireless control device in response to the movement of the first wireless control device in relation to the second wireless control device. The second control device may determine whether the signal strength of the wireless signals received from the first wireless control device has changed, and may associate the first wireless control device with the second wireless control device if the signal strength of the received wireless signals has changed. The second control device may be disassociated with the first control device by moving the first wireless control device in relation to the second wireless control device. The second control device may disassociate the first control device when the signal strength of subsequent wireless signals received from the first wireless control device has changed.

First claim

What is claimed is:

1 . An electrical control device couplable to an electrical load comprising:
communication interface circuitry; memory circuitry; and control circuitry communicatively coupled to the communication interface circuitry and to the memory circuitry, the control circuitry to: receive a maintained first input for a period of time responsive to a user actuation of an actuatable element disposed on a handheld device for the period of time; and for the duration of the maintained first input: receive, via the communication interface circuitry, a repeating broadcast signal from the handheld device; determine a respective signal strength of each received broadcast signal; determine a rate of change in the received signal strength of the broadcast signal over the period of time; determine a direction of motion of the handheld device based on the determined rate of change of the received signal strength of the broadcast signal; and perform one of: store data representative of a new control relationship with the electrical control device in the memory circuitry responsive to the detection of a first defined direction of motion of the handheld device; or remove data representative of an existing control relationship association with the electrical control device from the memory circuitry responsive to the detection of a second defined direction of motion of the handheld device.

2 . The electrical control device of claim 1 wherein, to receive the repeating broadcast signal from the handheld device, the control circuitry to further:
receive a repeating broadcast signal that includes a unique identifier associated with the handheld device.

3 . The electrical control device of claim 2 wherein, responsive to receipt of the maintained first input, the control circuitry to further:
enter a configuration mode responsive to receipt of the maintained first input.

4 . The electrical control device of claim 1 wherein, to detect the first defined direction of motion of the handheld device with respect to the electrical control device, the control circuitry to further:
determine whether a rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input indicates a movement pattern that corresponds to the first defined direction of motion of the handheld device with respect to the electrical control device.

5 . The electrical control device of claim 4 wherein, to determine whether the rate of change in the received signal strength of the repeating broadcast signal over the period of time of the maintained first input indicates the movement pattern that corresponds to the first defined direction of motion of the handheld device with respect to the electrical control device, the control circuitry to further:
determine whether an the rate of change in the received signal strength of the broadcast signal is increasing, indicative of the direction of motion of the handheld device is toward the electrical control device.

6 . The electrical control device of claim 1 , wherein, to detect the second defined motion of the handheld device with respect to the electrical control device, the control circuitry to further:
determine whether the rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input corresponds to the second defined direction of motion of the handheld device with respect to the electrical control device.

7 . The electrical control device of claim 6 wherein, to determine whether the rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input corresponds to the second defined direction of motion of the handheld device with respect to the electrical control device, the control circuitry to further:
determine whether the rate of change in the received a decreasing signal strength of the broadcast signal is decreasing, indicative of the direction of motion of the handheld device is away from the electrical control device.

8 . An electrical control device configuration method, comprising:
receiving, by control circuitry disposed in the electrical control device, a maintained first input for a period of time responsive to a user actuation of an actuatable element disposed on a handheld device for the period of time; and for the duration of the maintained first input: receiving, by the control circuitry via communicatively coupled communication interface circuitry, a repeating broadcast signal from a handheld device; determining, by the control circuitry, a respective signal strength of each received broadcast signal; determining, by the control circuitry, a rate of change in the received signal strength of the broadcast signal over the period of time; determining, by the control circuitry, a direction of motion of the handheld device based on the determined rate of change of the received signal strength of the broadcast signal; and performing, by the control circuitry, one of: causing, by the control circuitry, a storage of data representative of a new control relationship with the electrical control device responsive to the detection of a first defined direction of motion of the handheld device; or causing, by the control circuitry, removal of data representative of an existing control relationship with the electrical control device responsive to the detection of a second defined direction of motion of the handheld device.

9 . The method of claim 8 wherein, receiving the repeating broadcast signal from the handheld device, further comprises:
receiving, by the control circuitry via the communication interface circuitry, a repeating broadcast signal that includes a unique identifier associated with the handheld device.

10 . The method of claim 9 , further comprising:
entering, by the control circuitry, a configuration mode responsive to receipt of the maintained first input.

11 . The method of claim 8 wherein detecting the first defined direction of motion of the handheld device with respect to the electrical control device further comprises:
detecting, by the control circuitry, whether the rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input indicates a movement pattern that corresponds to the first defined direction of motion of the handheld device with respect to the electrical control device.

12 . The method of claim 11 wherein determining whether the rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input indicates the movement pattern that corresponds the first defined direction of motion of the handheld device with respect to the electrical control device further comprises:
determining, by the control circuitry, whether the rate of change in the received signal strength of the broadcast signal over the is increasing, indicative of the direction of motion of the handheld device is toward the electrical control device.

13 . The method of claim 8 whereinto detect the second defined motion of the handheld device with respect to the electrical control device further comprises:
determining, by the control circuitry, whether the rate of change in the received signal strength of the broadcast signal over the period of time of the maintained first input corresponds to the second defined direction of motion of the handheld device with respect to the electrical control device.

14 . The method of claim 13 wherein, determining whether the rate of chang
