     TECHNICAL FIELD 
       [0002]    The current invention relates to utility outlets and specifically the use of utility outlets in a security system. 
       BACKGROUND OF THE INVENTION 
       [0003]    Security systems are commonplace in commercial and residential premises. A security system typically includes a central processing control unit connected to several sensors around a premises. The sensors may be contact sensors installed at windows or doors or sensors that can detect motion. Retrofitting an existing building with a security system can be expensive if the new system is to be hard wired because it usually involves the alteration of existing structures such as walls. Consequently, there is a need for products and methods that allow the retrofitting of an existing building with minimal alteration to the building&#39;s structure. With regard to security systems for new construction, there is potential for reducing the number of devices that need to be installed in a premises. 
       BRIEF SUMMARY OF THE INVENTION 
       [0004]    The present invention is directed to the use of utility outlets in a security system. Utility outlets are pervasive in modern premises. Because most security systems require sensors to be located throughout a premises to detect security breaches and utility outlets are pervasive in most premises, it is advantageous to make utility outlets capable of detecting security breaches. The current invention uses utility outlets such as light switches, power sockets and permanently mounted light sockets to replace stand-alone security sensors. Because the utility outlets of the present invention have multiple functions, the use of these outlets would reduce the number of devices that need to be installed in a premises. Additionally, the use of utility outlets as security devices provides an opportune means of transmitting security related signals via electrical wiring of the premises. Transmission via the electrical wiring of the premises avoids the need for installing a separate wiring system solely for security purposes. This is particularly important in retrofitting an existing building with a security system. Further, the electrical wiring of the premises also supplies the utility outlet with the power required to operate the security system. 
         [0005]    An additional benefit of using utility outlets as a security system is that the utility outlet, if desired, may be made to detect changes in the connectivity status of electrical devices in relation to the utility outlet or the premises&#39; electrical supply. The connectivity status of a device to a utility outlet refers to whether the device is connected or not to the utility outlet. In the case of a power socket, this would mean whether the device is plugged into the power socket or not. Connectivity status of a device, such as a light bulb, to the premises&#39; electrical supply would mean whether the light bulb is on or off. 
         [0006]    When a change in connectivity status of a device to the utility outlet or power supply is unexpected, it may serve as an indicator of a security breach. For example, if a burglar unplugs a television set in a home, a contact sensor or other sensor in the utility outlet may detect this change. Further, a burglar who has turned a light switch on has connected the light to the electrical power and, if unexpected, this indicates a security breach. Accordingly, utility outlets provide an inconspicuous means of detecting a security breach by monitoring electrical devices&#39; connectivity to the utility outlets or premises&#39; power supply. 
         [0007]    Additionally, the detection of a breach based on the connectivity status of devices to utility outlets or power supply provides a “second tier” detection of a security breach where the detection of unauthorized entry to a premises is considered “first tier.” For example, an entity may not want a security system that detects unauthorized entry because the premises is open to the public continuously. However, that entity may consider it a security breach if certain devices are moved from a utility outlet or operated during certain periods. Accordingly, the current invention provides a way of detecting security breaches at a level typically not monitored by security systems—that is, security breaches that do not involve unauthorized entry within the premises. 
         [0008]    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. 
     
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         [0009]    For a more complete understanding of the present invention, reference is now made to the following descriptions taken in conjunction with the accompanying drawings, in which: 
           [0010]      FIG. 1  shows a light switch as one embodiment of the current invention. 
           [0011]      FIG. 2  shows a system using utility outlets in a security system as one embodiment of the current invention. 
       
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
       [0012]      FIG. 1  shows a light switch as one embodiment of the current invention. Light switch  10  includes an actuator  101 , a sensor  102  and a transmitter  103 . Actuator  101  switches a device on or off a premises&#39; electrical power. Sensor  102  is capable of detecting a security breach condition. A potential security breach condition is a condition that the security system detects and analyses to determine if in fact there has been a security breach. Sensor  102  may be a motion sensor that involves the use of any of the following: infrared light, high frequency sound emission and microwave signal emission. When sensor  102  detects motion, for example, transmitter  103  sends a signal to central processing unit (CPU)  107 . It should be noted that CPU  107  may be located in the utility outlet  10  but may also be located outside of and remote from the utility outlet  10 . CPU  107  determines whether the motion detected (the potential security breach) is a security breach based on preprogramming by a user, i.e. whether the user ‘armed’ the security system. If CPU  107  determines there is a security breach, CPU  107  sends a signal to an alarm device  104 , causing device  104  to alarm. Alarm device  104  may be located within utility outlets  10  or may be outside of and remote from utility outlets  10 . Alarm device  104  may be a microphone or an illuminating device that emits a squealing sound or a flashing light, respectively. Power cable  105  is a conduit for the premises&#39; power supply and is connected to utility outlet  10  by a terminal (not shown). Transmitter  103  may transmit signals via power cable  105 , communication cable  106 , or wirelessly. 
         [0013]    Utility outlet  10 , if desired, may also include sensors that detect changes to the connectivity status of a device with the utility outlet  10  or electrical power. When a device is unplugged from a power socket or when a light switch has been turned on or off, the utility outlet detects this and sends a signal to CPU  107 . Here, the invention takes advantage of the fact that in some scenarios the removal of electrical equipment from the premises and/or the operation of electrical devices on the premises, such as lights, garage openers etc. indicate a security breach. 
         [0014]      FIG. 2  shows a system using utility outlets in a security system as one embodiment of the current invention. The system includes a central processing unit (CPU)  201 . CPU  201  could be a personal computer, a control panel, or a processor located in some other device including one of the utility outlets. CPU  201  includes a memory  201 - 1 , a processor  201 - 2  and communication flow control  201 - 3 . CPU  201  is communicably connected to utility outlets  202   a - 202   n  via power line network  204 . Utility outlets  202   a - 202   n  are capable of connecting devices  203 - a - 203 - n  to the premises&#39; electrical power. A user, through an input device  206 , can “arm” the security system. 
         [0015]    Light switches are typically located close to the entrance of a room. Consequently, a light switch is ideally positioned to detect a security breach such as unauthorized entry into a premises. Light switch  202   a,  for example, may be located near a door in a premises. When light switch  202   a  detects motion, light switch  202   a  sends a signal to CPU  201 . If the system has been armed by a user, signals from a utility outlet will be processed by CPU  201 , which then sends a signal to another device such as a siren or a strobe light to cause an alarm. In some embodiments, the utility outlets  202   a - 202 - n  are equipped to emit a sound or to illuminate to create the alarm. In the latter scenario, CPU  201  would send a signal, to some or all the devices in the premises, that causes the utility outlets to alarm. 
         [0016]    Considering further examples, illustrated is power socket  202   b  which has a plug for a television  203 - b  plugged into power socket  202   b.  If someone disconnects television  203 - b &#39;s plug from power socket  202   b,  power socket  202   b  would send a signal to CPU  201 . CPU  201  would determine if this signal indicates a security breach. If the signal does indicate a security breach, then CPU  201  would send a signal to another device to create an alarm. 
         [0017]    Similarly, if hand drill  203 - c  is plugged into power socket  202   c,  power socket  202   c  would send a signal to CPU  201 . As described above, CPU  201  would process the signal and initiate the creation of an alarm if necessary. The communications between the CPU  201  and the utility outlets may be via cable network  204 . Cable network  204  may be a power cable network in the premises or other cable network within the premises. However, in some embodiments, communication by cable may be replaced or supplemented by wireless communication. It should be noted that CPU  201 , if desired, may be connected to an electronic network such as Internet  205  for sending a signal to a remote device.
