Abstract:
An alarm system for indicating the specific location of an intrusion into an enclosed space, as well as a method for installing the alarm system, are disclosed. The intrusion causes illumination of an indicator light outside the enclosed space and within the outer perimeter zone of the enclosed space, thereby indicating the specific location of the intrusion. At least one interior sensor located within the enclosed space generates a specific intrusion location signal in response to movement therein. A control system responsive to the specific intrusion location signal causes the indicator light to emit light that is visible from outside the outer perimeter zone of the enclosed space. The emitted light can indicate the specific location of an intrusion by directing light towards the specific intrusion location, and/or by surrounding the specific intrusion location, and/or by activating a light display that produces readable output of the specific intrusion location.

     FIELD 
     The invention relates generally to systems and methods for intruder detection, and more particularly to notification of an intruder detection event. 
     BACKGROUND 
     Security systems for protecting buildings and other structures from intrusion are well known in the art. Such security systems generally include one or more alarms to notify others of an attempted or actual intrusion. These alarms can include audible signals and/or lights to indicate when a breach or attempted breach of a structure, such as the prying open of a door or window, has occurred. Such security systems can help to protect building owners and/or inhabitants from would-be intruders and actual intruders, such as burglars. 
     While many of these systems activate alarms to notify others of attempted or successful intrusions, these systems typically do not provide information as to whether there was merely an attempted intrusion, or an actual intrusion. Other systems may activate an alarm only to indicate an actual intrusion, but the alarm may deactivate or may be deactivated before the user of the system arrives upon the scene of the intrusion. 
     Furthermore, without sound, the alarms of known alarm systems are not easily noticeable from outside an enclosed space that was intruded upon. For example, the alarms of some systems are small, inconspicuous, and silent panels of information about an intrusion. Still other alarms that do provide sound do not clearly identify and locate the enclosed space that was intruded upon. Even though a loud alarm may be activated upon intrusion, the general location of the enclosed space being intruded upon may be unclear or ambiguous to observers outside the enclosed space. 
     SUMMARY 
     An alarm system with an indicator light that is external to an enclosed space for indicating an intrusion into an enclosed space and the specific location of the intrusion into the enclosed space, and a method of installing such a system, are claimed. For example, the alarm system will show that the intrusion occurred at a specific wall or corner of the enclosed space, and/or a specific door or a specific window of the enclosed space, and/or some other specific portion of the enclosed space. 
     The system can be purchased and installed inexpensively and easily, and it can provide a signal that does not expire over time, and is easily recognizable and locatable to the user of the system upon the user&#39;s arrival at the enclosed space or the structure. The signal indicates the specific location of an intrusion into the enclosed space, thereby providing information to others regarding where an intruder might be lurking and perhaps lying in wait, within the enclosed space, and/or possibly where the intruder might exit as well. 
     Upon detecting an intrusion into the enclosed space, the alarm system employs an indicator light that is located within an outer perimeter zone that surrounds the enclosed space. Upon activation, the indicator light emits light that extends beyond the outer perimeter zone of the enclosed space as an intrusion alert, thereby reducing the need of a user to enter the outer perimeter zone of the enclosed space to determine the specific location of the intrusion. The alert is conspicuous and easily recognizable to anyone who approaches the outer perimeter zone of the enclosed space for which the external light alert is activated. An indicator light alarm is typically also easier for people to trace to its source than is a sound alarm, particularly if the enclosed space is situated close to other enclosed spaces with which it could be confused. The enclosed space can be a building, or a particular section or room of a building, for example. 
     The alarm system provides alerts regarding the specific location of an intrusion into an enclosed space and/or structure, in addition to alerting a user of an intrusion event generally. The alert provides specific location information regarding only successful intrusions into an enclosed space, as opposed to mere attempted intrusions. 
     The indication of the specific location of an intrusion into an enclosed space is information that can provide an observer with insight as to the nature of the intrusion, without requiring that the observer enter the enclosed space, or even enter the outer perimeter zone of the enclosed space. An alert indicating the specific location of an intrusion can therefore be helpful in a variety of ways, such as enhancing the decision-making process for the user or others investigating the intrusion, regarding how they would respond to the alert. 
     For example, information regarding the specific location of an intrusion can affect the decision-making process of someone investigating the intrusion, such as the police, on how to further investigate or respond to the intrusion. 
     The present alarm system having an indicator light that is external to an enclosed space for indicating the location of an intrusion into an enclosed space, can benefit from use with the invention disclosed in patent application Ser. No. 12/949,734, entitled “Alarm System Having An Indicator Light That Is External To An Enclosed Space For Indicating The Time Elapsed Since An Intrusion Into The Enclosed Space And A Method For Installing The Alarm System,” and filed on Nov. 18, 2010.

     DETAILED DESCRIPTION 
       FIG. 1A  is a block diagram showing the main elements of an embodiment of the alarm system. In the embodiment represented by the diagram of the system elements  100 , several interior sensors are placed within an interior space of a building, which in this case is a house. 
     The enclosed space to be equipped with the alarm system can be any building or enclosed portion of a building (such as a section or room of the building) for which a user of the system wishes to receive notice of the intrusion by another into the enclosed space. Such enclosed space can include rooms, sections, levels, or entire internal areas of buildings such as houses, apartments, schools, dorm rooms, office buildings, factories, or any other buildings apparent to one of ordinary skill in the art of intrusion alert systems. 
     In the embodiment shown, the sensors are placed in such a manner so as to detect intrusion of the building. In alternative embodiments, sensors can be strategically placed so as to detect intrusion of a certain particular enclosed space of the building, such as a particular room or group of adjacent rooms, or an entire floor level of the building, for example. The exemplary sensors shown include a door sensor  102 , a window sensor  104 , a chimney sensor  106 , and an internal area sensor  108 . 
     Sensors can be placed in proximity to access points to the building or an enclosed portion of the building, so as to detect intrusion of the enclosed space through the access point. Such access points which the sensor may be placed near can include a door  102 , window  104  or chimney  106 , for example. Another sensor can be placed within a general internal area of an enclosed space  108 , so as to detect movement inside the enclosed space, or so as to employ any other means of detecting intrusion apparent to one of ordinary skill in the art of intrusion detection. 
     The sensors can be any kind of sensor configured to detect intrusion, such as a heat sensor or infrared sensor, for example. One skilled in the art will appreciate and readily acknowledge other possible sensors which can be used. If an intrusion occurs, a sensor will detect the intrusion and send a specific intrusion location signal to a control unit  110 . The control unit  110  will send the specific intrusion location signal to an indicator light located outside the enclosed space and in an outer perimeter zone of the enclosed space. The control unit  110  can serve as a light control system, configured to control the light so as to indicate the location of intrusion. 
     The indicator light will emit light so as to indicate that an intrusion has occurred, and to indicate the location of the intrusion. Other sensors positioned and configured to detect movement within the enclosed space for which intrusion is to be detected will be readily apparent to one ordinarily skilled in the art of intrusion detection. A light control system controls light emitted by the indicator light so as to indicate the location of the intrusion. 
       FIG. 1B  is an elements diagram showing the interaction between the main elements of an embodiment of the alarm system, wherein the main elements are hard wired together with electrical wiring. A house  120  equipped with an embodiment of the alarm system is shown, containing a door sensor  122 , window sensor  124 , chimney sensor  126 , and internal area sensor  128 . 
     As depicted in this diagram, the sensors are hard wired to a common control unit  130 , which in turn is in hard wire communication with an indicator light  132 . In the embodiment shown, the control unit  130  is located outside the structure of the house  130 . Upon receiving a specific intrusion location signal from any of the sensors, the control unit  130  can propagate the signal to the indicator light  132  located in the outer perimeter zone of the enclosed space, which emits light that is visible beyond the outer perimeter zone of the enclosed space, thereby alerting others to an intrusion and the location of the intrusion. In this embodiment, the indicator light  132  is located outside the house but within a curtilage of the house  120 , and produces light that is visible beyond the curtilage. 
     In the embodiment shown, the indicator light  132  emits a light beam  133  that is directed towards the location of the intrusion, so as to indicate the location of the intrusion. In this example, the light  133  is directed towards the front door of the house, so as to indicate that the house was intruded via the front door. 
       FIG. 1C  is an elements diagram showing the interaction between the main elements of an alternative embodiment of the alarm system wherein the main elements are connected together via wireless signaling. A house  120  equipped with an embodiment of the alarm system is shown, containing a door sensor  122 , window sensor  124 , chimney sensor  126 , and internal area sensor  128 . 
     As depicted in this diagram, the sensors are linked via wireless connection to a common control unit  140 , which in turn is in wireless communication with an indicator light  132 . In the embodiment shown, the control unit  140  is located inside the structure of the house  120 . Upon receiving a specific intrusion location signal from any of the sensors, the control unit  130  can propagate the signal to the indicator light  132  located in the outer perimeter zone of the enclosed space, which emits light that is visible beyond the outer perimeter zone of the enclosed space, thereby alerting others to an intrusion and the location of the intrusion. In this embodiment, the indicator light  132  is located outside the house but within a curtilage of the house  120 , and produces light that is visible beyond the curtilage. 
     In the embodiment shown, the indicator light  132  emits a light beam  133  that is directed towards the location of the intrusion, so as to indicate the location of the intrusion. In this example, the light  133  is directed towards the front door of the house, so as to indicate that the house was intruded via the front door. 
       FIG. 2A  is an aerial view of a house equipped with an installed version of an embodiment of the alarm system, showing the light output indicating a specific location of an intrusion. In this embodiment, the house  200  is equipped with an indicator light  202  that emits a continuous light beam  203 . 
     In the embodiment shown in this figure, the light beam  203  is a window light  113  directed at a window through which the house has been intruded upon. Therefore, in this embodiment the indicator light  202  indicates the location of intrusion by directing the light beam  203  towards the specific intrusion location. 
       FIG. 2B  is an aerial view of a house equipped with an installed version of the embodiment shown in  FIG. 2A , showing the light output indicating a more general location of an intrusion. In this embodiment, the house  200  is equipped with an indicator light  202  that emits a continuous light beam  204 . 
     In the embodiment shown in this figure, the light beam  204  is a general area light  115  directed at a corner section of the house. The light beam  204  indicates that intrusion occurred within one of the entry points illuminated by the light beam  204 , including a front-facing window and a side-facing window. Such general information can be the result of an internal area sensor  108 , for example. The specific intrusion location signal will therefore provide more general information, than a specific intrusion location signal sent by a sensor dedicated to detecting intrusion of a specific access point, such as the embodiment shown and discussed in  FIG. 2A . 
       FIG. 3  is an aerial view of a house equipped with an embodiment of a combination of indicator lights of the alarm system. A house  200  is equipped with an indicator light  202  that emits a continuous light beam  300 . In addition, this embodiment also includes a light display  302  capable of producing a readable output of the location of the intrusion, wherein the light control system is configured to control the readable output that is produced by the light display  302 . In the embodiment shown, the light display  302  is located on a wall near a doorway into the house  200 . The light display  302  is indicating that intrusion occurred through a kitchen window of the house  200 . 
       FIG. 4  is an aerial view of a house equipped with an alternative embodiment of a combination of indicator lights of the alarm system. A house  200  is equipped with an indicator light  400  that emits a beacon light  400 , such as light emitted omni-directionally from a bulb, as opposed to a focused beam. The beacon light  400  can be light of continuous output, or alternatively, it can be light of non-continuous output, such as a blinking light. The beacon light  400  is installed at the top of the house  200 . 
     In addition, this embodiment also includes a light display  402  capable of producing a readable output of the location of the intrusion, wherein the light control system is configured to control the readable output that is produced by the light display  402 . In the embodiment shown, the light display  402  is located on a wall around the corner from a doorway into the house  200 . The light display  402  is indicating that intrusion occurred through a kitchen window of the house  200 . 
       FIG. 5  is an aerial view of a house equipped with another alternative embodiment of a combination of indicator lights of the alarm system. In this embodiment, the house  200  is equipped with a rotating light beam  500 , which is installed at the top of the house  200 . The light beam  500  is projected substantially horizontally from a rotating light source. In the embodiment shown, the rotating light beam  500  is a focused light beam which rotates about the vertical axis of its light source. This rotating light  600  can potentially alert others in all directions beyond the curtilage of the house  400 , potentially including those located within neighboring dwellings. 
     In addition, this embodiment also includes a light display  500  capable of producing a readable output of the location of the intrusion, wherein the light control system is configured to control the readable output that is produced by the light display  500 . In the embodiment shown, the light display  500  is located on a walkway towards a doorway of the house  200 . The light display  500  is indicating that intrusion through a kitchen window of the house  200 . 
       FIG. 6  is side view of a house equipped with another alternative embodiment of a combination of indicator lights of the alarm system. In the embodiment shown, a house  600  includes a light display  602  comprised of a plurality of lights surrounding the perimeter of a possible location of intrusion. In the embodiment shown, a series of lights surround the perimeter of a window. The lights are illuminated, thereby alerting others that the house  200  has been intruded upon, via the window that is illuminated by the light display  602 . 
       FIG. 7  is an illustration of a component of an embodiment of the alarm system, wherein a specific intrusion location message is produced on a mobile device. In the embodiment shown, a mobile device  700  receives a specific intrusion location message  702 , in addition to an indicator light signal being projected from the outer perimeter zone of the enclosed space with which the indicator light is associated. Such a mobile device specific intrusion location message  702  can supplement the indicator light, providing an enhancement to the alarm system. For example, if an intrusion is detected, the alarm system can alert those for whom the intruded enclosed space is in sight. In addition, a user of the alarm system can receive an alert  702  on their mobile device  700 , which can be an important and useful supplemental alert if and when they are not near or approaching the enclosed space. In the embodiment shown, the specific intrusion location message  702  indicates that intrusion occurred through a kitchen window of the house. 
       FIG. 8  is an illustration of a room within a building employing an embodiment of the alarm system. In this embodiment, the alarm system is configured to alert others of the location of an intrusion into an enclosed space within a building, in this instance the enclosed space being a room of a house. In this embodiment, a room  800  adjacent to the intruded room is equipped with an indicator light  802 . The indicator light in this example is a light display  802  which indicates readable output concerning the location of the intrusion. 
     The light display  802  shown is capable of producing a readable output of the location of the intrusion, wherein a light control system is configured to control the readable output that is produced by the light display. In the embodiment shown, the light display  802  is located above a doorway  804  which leads from the adjacent room  800  into the intruded room. The light display  802  is indicating that intrusion occurred through the door. 
     The indicator light  802  is located within the outer perimeter zone of the room equipped with the alarm system, and the light display  802  is visible and readable beyond the outer perimeter zone of the room equipped with the alarm system. For example, someone in the adjacent room  800  could easily see the light display and read the output. In some embodiments, several such indicator lights  802  may be placed at various locations within the outer perimeter zone of the enclosed space equipped with the alarm system, so as to alert others in various neighboring rooms, for example. 
     If an unexpected intrusion occurs in one room, the indicator light  802  can alert others in adjacent rooms  800  of the intrusion, for example. In other embodiments, the enclosed space under surveillance may be a group of rooms, or some other portion of a building, for example. The indicator light  802  is located in the outer perimeter zone immediately outside the enclosed space under surveillance. In this case, the outer perimeter zone includes the doorway  804  and wall of an adjacent room  800 . The indicator light  802  is therefore mounted on the adjacent wall of the doorway  804  connecting the intruded room with the adjacent room  800 . 
     The alarm system can be activated through a variety of techniques, some of which are discussed explicitly in this specification, while still others will be readily apparent to one of ordinary skill in the art.  FIG. 9A  depicts a keypad  900  configured to control an activating system in an embodiment of the alarm system. Such a keypad can be installed on an outer wall of a house, near an entrance into the house for example, or somewhere near the house and within the curtilage of the house, for example. The keypad is connected to and capable of communicating with an activator  902  which can activate the system. 
       FIG. 9B  depicts a manual key and lock configured to control an activating system for an embodiment of the alarm system. In this embodiment, a manual key  904  can fit into a manual keyhole  906 , and whereupon the key  904  is inserted into the keyhole  906  and turned, the alarm system can be activated and/or deactivated via communication with an activator  902 . 
     The alarm system can also be activated via remote devices.  FIG. 9C  depicts a dedicated remote device  908  and a receiver  910 , which in combination are configured to control an activating system in an embodiment of the alarm system. A user of the system can activate the system using a remote control  908  which communicates with a receiver  910 , which in turn is linked to an activator  902 .  FIG. 9D  depicts a personal mobile device  912  and reception tower  913  in communication with a receiver  914 , which in turn is linked to an activator  902  and configured to control an activating system for an embodiment of the alarm system. Still other activation systems will be readily apparent to one of average skill in the art. 
       FIG. 10  is a flowchart depicting a sequence of events related to an embodiment of the alarm system in use, in relation to a structure. First, a potential intruder attempts to breach and/or intrude a structure or other enclosed space equipped with the system  1000 , with intent to intrude the structure or enclosed space. In this embodiment, the entire structure is equipped with the system, while in alternative embodiments only a sub-enclosure, such as a room within the structure, might be so equipped. 
     If the intruder succeeds in intruding the structure  10002 , an interior sensor will detect the intrusion  1004  and generate an intrusion signal  1006 , which in the present invention is a specific intrusion location signal indicating the location of the intrusion. If the system includes for the specific intrusion location signal to be sent to a user&#39;s mobile device  1008 , then the mobile device can be alerted  1010 . The specific intrusion location signal is sent to an indicator light  1012 , which then activates and outputs an alarm light  1014  upon receiving the information regarding the intrusion time signal. The indicator light indicates the location of intrusion. This completes the main operation of the system  1016 . 
     Other modifications and implementations will occur to those skilled in the art without departing from the spirit and the scope of the invention as claimed. Accordingly, the above description is not intended to limit the invention except as indicated in the following claims.
