     TECHNICAL FIELD 
       [0002]    The current invention relates to utility outlets and specifically to the use of utility outlets as repeaters for remote control signals. 
       BACKGROUND OF THE INVENTION 
       [0003]    Today, a remote controller can control most devices used in premises. Most of these remote controllers emit infrared signals or radio waves to control the target device. Typically, however, the remote controller has to be in close proximity to the device being controlled or at least be able to “see” the device being controlled i.e. there are no objects in the transmission space between the remote controller and the device being controlled. Consequently, typical remote controllers become ineffective when the device to be controlled is in a different room, from the room in which the user with a remote controller is located. 
       BRIEF SUMMARY OF THE INVENTION 
       [0004]    The present invention is directed to devices, systems and methods of improving the effectiveness of the use of remote controllers in premises in situations where the remote controller is not in proximity to the device being controlled. The present invention takes advantage of utility outlets that are present in most premises rather than using devices with the sole function of operating as a repeater. The use of utility outlets takes advantage of the fact that utility outlets are invariably installed in every room of premises. Further, the utility outlets are connected within the premises by a wire network that serves to deliver power to the premises, and the wire network then can also serve as a conduit for the transmission of signals from one utility outlet to the other. The use of utility outlets, therefore, obviates the cost and the inconvenience of having several stand-alone repeaters plugged into power sockets within premises. 
         [0005]    In embodiments of the current invention, the utility outlet in proximity to the remote controller functions as a receiver of control signals from a remote controller. Other utility outlets may function as a repeater of a remote control signal by sending received signals from one utility outlet to another by the electrical wiring network of the premises. The utility outlet in proximity to the device to be controlled, upon receiving a signal from another utility outlet, transmits a control signal to the device to be controlled. Because the signals are transmitted from utility outlet to utility outlet by wire, the problems of too much distance from the remote controller to the device and interferences between the remote controller and the device are avoided. 
         [0006]    The foregoing has outlined rather broadly the features and technical advantages of the present invention in order that the detailed description of the invention that follows may be better understood. Additional features and advantages of the invention will be described hereinafter which form the subject of the claims of the invention. It should be appreciated by those skilled in the art that the conception and specific embodiment disclosed may be readily utilized as a basis for modifying or designing other structures for carrying out the same purposes of the present invention. It should also be realized by those skilled in the art that such equivalent constructions do not depart from the spirit and scope of the invention as set forth in the appended claims. The novel features which are believed to be characteristic of the invention, both as to its organization and method of operation, together with further objects and advantages will be better understood from the following description when considered in connection with the accompanying figures. It is to be expressly understood, however, that each of the figures is provided for the purpose of illustration and description only and is not intended as a definition of the limits of the present invention.

           [0008]      FIGS. 1 AND 2  illustrate a utility outlet as one embodiment of the current invention; 
           [0009]      FIG. 3  illustrates a plurality of utility outlets being used to remotely control devices; and 
           [0010]      FIG. 4  is a flow diagram illustrating one embodiment of a process involved in using utility outlets as remote control repeaters to control a device. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0011]      FIG. 1  illustrates one embodiment  10  of the current invention. Utility outlet  10  is a power socket used in a premise to allow devices to connect to electrical power. In addition to connecting devices to electrical power, utility outlet  10  also includes receiver  101  for detecting control signals from a remote control device, for example, infrared (IR) sender  11 . Utility outlet  10  also includes communicator  102  for sending a peer-to-peer signal via wire to another utility outlet. Peer-to-peer, in the current application, means a signal from one utility outlet to another and is transmitted, preferably, by the electrical wire network in the premises, such as wire  12 . However, the peer-to-peer signal could also be transmitted wirelessly or by a wire separate from wire  12  connected to terminals (not shown) on device  10 . 
         [0012]    Utility outlet  10  may also be capable of receiving a peer-to-peer signal from another utility outlet via receiver  103  (which could be, if desired, combined with receiver  101 ). In response to the receipt of the remote control signal, receiver  103  communicates with remote control transmitter  104 . Remote control transmitter  104 , in response to the communication from receiver  103 , sends a remote control signal to a device, such as device  13 , to be controlled. To determine whether to send a signal to another utility outlet or to send a remote control signal to a device to be controlled, utility outlet  10  may be equipped with a processor such as processor  105 . Processor  105  is capable, if desired, of allowing a user to preprogram utility outlet  10  to determine whether a received peer-to-peer signal should be retransmitted to another utility outlet or should be converted to a remote control signal that is transmitted to a device in proximity to the utility outlet. Similarly, where utility outlet  10  receives a remote control signal from a remote controller, processor  105  determines whether a peer-to-peer signal should be transmitted in response to the remote control signal or whether nothing should be done. Processor  105  determines whether and which signal is to be transmitted based on user preprogramming of remote control signal codes of the remotely controlled devices in the presence of the utility outlet. 
         [0013]      FIG. 2  illustrates utility outlet  20  where the utility outlet  20  is an electrical socket. In this example, the utility outlet  20  has receiver  201  to receive a peer-to-peer signal and transmitter  202  to transmit received peer-to-peer signals to another utility outlet. In this example, utility outlet  20  functions as a repeater of peer-to-peer signals and does not receive or emit remote control signals from or to local devices. Note that while the utility devices shown are power sockets, any utility device, such as a switch, light fixture, or socket can be used. 
         [0014]      FIG. 3  illustrates an example of how a plurality of utility outlets may be used as repeater stations to remotely control a premises&#39; devices. Building  30  has several rooms, including bedroom  301 , family room  302  and garage  303 . Television (TV)  307  is controllable by a remote controller. Even though TV  307  is capable of responding to a remote control signal from a remote controller, such as from device  304 , a user in bedroom  301  may not be able to control TV  307  from bedroom  301  directly from the hand-held device. The inability of device  304  to control TV  307  may be due to the distance from bedroom  301  to family room  302  or because of the walls within building  30  preventing signals, such as IR signals, from device  304  in bedroom  301  from reaching TV  307  in family room  302 . 
         [0015]    In this example the invention solves the problem of not being able to control TV  307  from bedroom  301  by allowing utility outlet  305  in bedroom  301  to receive the signal from remote controller  304 . Utility outlet  305  then transmits a signal over the premises&#39; wiring to utility outlet  306  inside room  302 . In response to the signal received from utility outlet  305 , utility outlet  306 , being in proximity to TV  307 , sends a remote control signal, IR or otherwise, to control TV  307 . This obviates the need for the user to enter family room  302  to remotely control TV  307 . 
         [0016]    In another example depicted in  FIG. 3 , the user may want to close garage door  309  without having to leave bedroom  301 . In this example, the bedroom is far from the garage and there are intervening walls preventing a signal from remote control  304  from directly controlling the garage door. The current invention allows the user to close the garage door by a series of utility outlets operating as either a signal receiver, signal repeater, or signal transmitter, or a combination thereof. 
         [0017]    In this example, from bedroom  301 , user  304  sends a remote signal with the appropriate code to control garage door  309 . Utility outlet  305  detects this code and determines that it does not control a device in room  301 . Device  305  then sends a peer-to-peer signal to utility outlet  306 . Utility outlet  306  receives this peer-to-peer signal, detects that the control of a device in room  302  is not intended and transmits another peer-to-peer signal to utility outlet  308 . Utility outlet  308  receives the peer-to-peer signal, detects that it is for controlling garage door  309  and converts it to a remote control signal with a code to control the closing of garage door  309 . Note that a look-up table (not shown) in device  305  (or in a device accessible by device  305 ) could have been used to route the control signal instead of relaying the signal through device  306 . 
         [0018]    It should be noted that any household device or personal device on the premise may be controlled by this invention. For example, a user may wish, from his or her bedroom to send a signal to open a garage door and then send another signal to start the car to warm up. 
         [0019]      FIG. 4  shows flow diagram  40  illustrating the processes involved in one example of the invention. This example begins with process  401  where the utility outlet determines whether a signal has been received from a remote controller. When a signal has been received from a remote controller, process  402  running, for example, in a utility device local to where the signal is sent from, determines if the received signal is intended for controlling a device in the proximity of the remote controller. If the received signal is for controlling a device in the proximity of the receiving utility outlet, then the utility outlet does nothing. If the received signal is for controlling a device not in the proximity of said utility outlet, process  403  sends a signal to another utility outlet. 
         [0020]    Process  404  determines whether the utility outlet receiving the signal from the sending outlet is in proximity to the device to be controlled. If the receiving utility outlet is not in proximity with the device to be controlled then the process of peer-to-peer signals will be repeated until a receiving utility outlet is in proximity to the device to be controlled. If process  404  determines that the receiving utility outlet is in proximity to the device to be controlled then this example concludes when process  405  emits a remote control signal to control the device.
