System and method for associating items of a set

1. A system for facilitating locating of a first item of a set of items, the system comprising:

a first wireless communication device associated with the first item of the set, the first wireless communication device including an output device and a first wireless receiver;

a second wireless communication device associated with a second item of the set, the second wireless communication device including an input device and a first wireless transmitter;

wherein the second wireless communication device in response to a first input signal provided via the input device transmits a first wireless signal by way of the first wireless transmitter,

wherein the first wireless communication device receives the first wireless signal and provides a first output signal in response to receiving the first wireless signal,

wherein the first output signal is at least one of sufficiently visible and sufficiently audible so as to facilitate the locating of the first item of the set in a circumstance in which the first item is not yet located by a person, so that the first item can be associated with the second item,

wherein the first and second items during an absence of the first and second wireless communication devices would be unable to communicate a wireless signal therebetween from the second item to the first item,

wherein the first and second items are complementary items or identical items; and

wherein the first and second items are first and second socks of a pair of socks.

2. The system of claim 1 , wherein functional purposes of the first and second items during the absence of the first and second wireless communication devices do not include any wireless communication function.

3. The system of claim 1 , wherein the input device is a user-actuatable membrane switch, and the output device is at least one of a sonic output device and a light emitting device.

4. The system of claim 1 , wherein each of following is true:

the second wireless communication device includes a membrane switch that is the input device and the first wireless communication device includes a high-pitch beep generator that is the output device;

the first wireless receiver of the first wireless communication device includes a microstrip patch antenna;

the first wireless communication device includes means for attaching that is selected from the group consisting of an adhesive structure, a Velcro structure, a button, a hook, a clasp, a snap, or a fastener, a sewn link, a tied linkage, a welded portion, and a molded portion;

the first wireless communication device is designed to withstand environmental conditions to which the first item is likely to be subject; and

wherein the first wireless communication device is configured to have sufficient power to last approximately an expected lifetime of the first item.

5. A method of locating a first item of a set of items, the method comprising:

providing an input command to a first wireless communication device associated with a second item of the set in a circumstance in which the first item is not yet located by a person, so that the first item can be associated with the second item;

transmitting a first wireless signal from the first wireless communication device to a second wireless communication device associated with the first item of the set;

outputting at least one of an audible signal and a visible signal front the second wireless communication device,

wherein the first and second items during an absence of the first and second wireless communication devices would be unable to communicate a wireless signal therebetween from the second item to the first item,

wherein the first and second items are complementary items or identical items, and

wherein the first and second items are first and second socks of a pair of socks,

whereby the person searching for the first item is able to sense the audible or visible signal and thereby locate the first item of the set.

6. The method of claim 5 , further comprising:

attaching the first wireless communication device to the second item by way of first means for attaching,

and attaching the second wireless communication device to the first item by way of second means for attaching.

7. The method of claim 6 , wherein the providing, transmitting, and outputting are repeated at least once.

8. The method of claim 7 , wherein each of following is true:

the second wireless communication device includes a membrane switch that is an input device and the first wireless communication device includes a high-pitch beep generator that is an output device;

the first wireless receiver of the first wireless communication device includes a microstrip patch antenna;

the means for attaching is selected from the group consisting of an adhesive structure, a Velcro structure, a button, a hook, a clasp, a snap, or a fastener, a sewn link, a tied linkage, a welded portion, and a molded portion;

the first wireless communication device is designed to withstand environmental conditions to which the first item is likely to be subject; and

wherein the first wireless communication device is configured to have sufficient power to last approximately an expected lifetime of the first item.
