       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of the Invention  
           [0003]    The invention relates generally to an improved motion detector and alarm system for actuating an alarm device in response to movement of an object, and more particularly to a portable motion detector and alarm system which is easy to install and operate and is capable of detecting motion relative to a variety of predetermined positions.  
           [0004]    2. Prior Art  
           [0005]    The problem of protecting homes, businesses and other premises against unauthorized intrusions is becoming increasingly important due to the increase in vandalism, theft and even physical attacks upon the inhabitants. Various prior art systems have been developed to address the problem and numerous examples exist of alarm or warning devices. One commonly used protective system involves wiring doors and windows in such a manner that an unauthorized opening of the door or window activates an electric circuit which in turn produces an alarm.  
           [0006]    For example, U.S. Pat. No. 4,271,405 to Kitterman discloses an alarm control system for protecting a premises including a four conductor bus line leading from a master control station and extending about the interior perimeter of the premises. Sensors positioned near each port of entry to be monitored are connected in parallel relationship to the bus line. Each sensor carries a biased reel carrying line secured to a window, door, screen or the like. Disturbance of a sensor causes a magnetically responsive switch therein to generate a pulse triggering circuitry within the control station to activate the desired alarm device.  
           [0007]    While effective, this system requires extensive wiring of the premises as a bus line must be routed about the interior perimeter of the premises between a master control station and the ports of entry at which the motion sensors are to be located. Hence, this system is time consuming and complicated to install, and installation may require expertise beyond that of the average home or business owner. Once installed, the sensors of this system are not easily relocated. Further, the system may be defeated by cutting the wires extending between the sensors and the master control station.  
           [0008]    U.S. Pat. No. 3,781,836 to Kruper et al discloses an alarm system including a magnetic pulse generator for producing an output pulse in response to a change in magnetic flux in response to an intrusion of a designated area. A radio transmitter circuit responds to the pulse from the magnetic pulse generator by transmitting a signal to a remote receiver circuit which in turn generates a pulse for actuating an intrusion alarm circuit. The system requires a complex linkage assembly to translate motion of the object to motion of a magnet. In addition a relatively bulky pick-up coil assembly is necessary to generate the pulse to be applied to the transmitter circuit.  
           [0009]    U.S. Pat. No. 3,696,380 to Murphy discloses a portable alarm device with a battery or low voltage operated sound signal triggered by a magnetic reed switch which is closed to complete the circuit by a magnet attached to a movably mounted arm, the poles of the magnet being positioned perpendicular to the longitudinal dimension of the contact strips of the reed switch to cause the reed switch to close when the magnet is in either of two positions relative to the switch.  
           [0010]    A need remains for a motion detection and signal generating system which is small in size, easily transportable, easy to install and which can sense motion relative to any desired initial position of an object. An additional desirable capability of the foregoing system would be to provide information about the detected motion to the owner of the object, or a remote location such as a law enforcement or other security agency It would likewise be desirable to provide identification information about a specific object whose motion has been detected in the event that the motion detection and signal generating system is implemented to detect motion at multiple locations (e.g., doors, windows) within a larger security area (e.g., a residence, an office or otherwise).  
         BRIEF SUMMARY OF THE INVENTION  
         [0011]    Accordingly, it is a principal object of the invention to provide a system for detecting the movement of an object comprising: an object whose movement is to be detected, movable magnet means coupled to the object such that movement of the object results in movement of said movable magnet means, and means for detecting movement of the movable magnet means and providing an indication of the movement. The means for detecting is in communication with the movable magnet means.  
           [0012]    The system further includes radiating means for wirelessly transmitting a predetermined signal in response to the indication of movement, the radiating means being coupled to the means for detecting. The object whose movement is to be detected may be coupled to the movable magnet means by a wire means which can also serve as the radiating means.  
           [0013]    The system further includes means for receiving the predetermined signal, the means for receiving being separate from and located at a distance from the radiating means. The system preferably includes means for generating an alarm signal when the predetermined signal is received by the means for receiving. The alarm signal thus generated may be audible, visual or electronic and may include speakers, warning horns, lamps and the like.  
           [0014]    It is a further object of the invention to provide a method of detecting movement of one or more objects comprising the steps of: a) coupling each object whose movement is to be detected to a corresponding movable magnet such that movement of any object results in movement of the corresponding magnet; b) detecting the motion of the corresponding magnet; c) transmitting a predetermined signal in response to the detected motion, and, d) receiving the predetermined signal at a distance from the object, or objects, whose motion is to be detected.  
           [0015]    The method may include the further step of providing an alarm signal when the predetermined signal is received by the receiver means. The alarm signal may be audible, visible, or may be an electronic alarm signal which is transmitted to a remote alarm center via a telecommunications means such as a telephone line.  
           [0016]    It is a further object of the invention to provide a movement detection and alarm system which may be affixed to a wide variety of objects including inside doors, outside gates, garage doors, children&#39;s barriers such as “baby gates”, valuable wall hangings and paintings, and countless other objects.  
           [0017]    It is a further object of the invention to provide a movement detection and alarm system which is portable and is easily packed in a suitcase and transported with a traveler to be later installed on motel or hotel room doors, windows and/or any objects within the room, whenever additional protection is desired by the traveler.  
           [0018]    It is a further object of the invention to provide a movement detection and alarm system that provides movement information to a remote location, such as a law enforcement or security agency.  
           [0019]    It is a further object of the invention to provide a movement detection and alarm system wherein the movement information includes an indication of the distance that is moved for measuring purposes.  
           [0020]    It is a further object of the invention to provide a movement detection and alarm system that provides object identification information either locally at or near the site of the object or remotely to a designated location such as a telephone number, email address, etc.  
           [0021]    It is a further object of the invention to provide a movement detection and alarm system wherein the object identification information is locally or remotely programmable.  
           [0022]    It is a further object of the invention to provide a movement detection and alarm system wherein the movable magnet means and the radiating means are part of a remotely controllable trigger unit having both a radio transmitter and a radio receiver.  
           [0023]    The present invention relates to a portable security alarm system which can be installed on a temporary basis and removed from an object whose movement is to be detected comprising a motion detecting and radio signal transmitting member, means for selectively coupling and decoupling said motion detecting and radio signal transmitting member relative to said object whose movement is to be detected, and a combined radio signal receiving and alarm generating member for receiving a signal from said combined motion detecting and radio signal transmitting member and producing an alarm. The alarm system also preferably includes a remote control member for selectively actuating and deactuating said combined radio signal receiving and alarm generating member. The alarm system also preferably includes an information gathering device for gathering movement information and a remote notification device for providing the movement information to a remote location. As an optional feature, the alarm system can be implemented such that the signal from the combined motion detecting and radio signal transmitting member includes an identification code that is used to provide object identification information either locally or to a remote location. Local or remote programmable means can be provided for selectively associating the object identification information with the identification code. As an additional optional feature, the combined motion detecting and radio signal transmitting member can be adapted to provide distance information representing a distance moved by an object whose movement is to be detected. The combined motion detecting and radio signal transmitting member can also include radio signal receiving means and control logic means to facilitate remote control of the device for polling or programming purposes.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0049]    The following detailed description of the embodiments of the present invention, as represented in FIGS.  1 - 10 , is not intended to limit the scope of the invention, as claimed, but is merely representative of the presently preferred embodiments of the invention. The presently preferred embodiments of the invention will be best understood by reference to the drawings, wherein like parts are designated by like numerals throughout.  
         [0050]    [0050]FIG. 1 shows, in pictorial block diagram form, the major components of the movement detecting device and alarm system  10  of the present invention. The system is comprised of at least one movement detecting and signal transmitting means  20 , including a retractable wire means  22 , a receiver means  30  and a remote control means  40 .  
         [0051]    More than one movement detecting and signal transmitting means  20  may be utilized in implementing the system of the present invention. One movement detecting and signal transmitting means  20  may be placed on each object whose movement it is desired to detect. For example, in a room with four windows  25  and two doors  24 , six movement detecting and signal transmitting means  20  may be utilized, one on each window and one on each door. However, only one receiver means  30  is necessary regardless of the number of movement detecting and signal transmitting means  20  used. There is no limit to the number of movement detecting and signal transmitting means  20  which may be used with one receiver.  
         [0052]    Each movement detecting and signal transmitting means  20  is coupled to one object, such as a door  24 , or window  25 , whose movement is to be detected. In a preferred embodiment, the coupling means is a retractable wire  22  which extends from movement detecting and signal transmitting means  20  to the object,  25  or  24 , whose movement is to be detected. One end of retractable wire  22  is affixed to the object and the other is coupled to movable magnets (best illustrated in FIGS. 4,5 and  6 ) located inside casing  31  of movement detecting and signal transmitting means  20 . Typical means of affixing the end of retractable wire  22  to an object include VELCRO tabs, glue, removable tape, and the like.  
         [0053]    Receiver means  30  is configured to receive a predetermined signal which is wirelessly transmitted by movement detecting and signal transmitting means  20  whenever the object whose movement is to be detected, is displaced from a predetermined position. The object whose movement is to be detected need not be in any particular position when the end of retractable wire  22  is affixed thereto. If the object is a window, such as depicted at  25 , the window may be closed, or it may be partially or fully open, when retractable wire  22  is affixed. Any displacement from its position when retractable wire  22  is affixed will be detected and alarmed.  
         [0054]    Accordingly, a window may be left in a partially open position, as for example, to provide fresh air to a room, while the occupant attends to other matters, or sleeps. Any displacement from the partially open position will cause the alarm signal to be generated. Even in a situation wherein an intruder reached into the window and removed movement detecting and signal transmitting means  20  from the window, the predetermined signal would be transmitted and the alarm signal generated, thus warning the occupant of an intrusion.  
         [0055]    Receiver means  30  can be any receiver known in the art capable of receiving the signal transmitted through retractable wire  22 . In response to the transmitted signal, receiver means  30  initiates a local alarm which can be audible or visual. In addition, receiver means  30  may initiate contact with police, medical, rescue or other emergency facilities or agencies. Receiver means  30  can be AC powered and may be equipped with an on/off switch. Receiver means  30  need not be co-located with movement detection and signal transmitting means  20  and can be positioned anywhere within reception distance of the transmitted signal. Receiver means  30  may be positioned anywhere about the room or the area to be protected and may be placed up to a distance of 150 ft. to 200 ft. or greater from movement detecting and signal transmitting means  20 .  
         [0056]    In a preferred embodiment receiver means  30  is powered by alternating current (AC). Therefore, it must be located such that a power cord, or an extension thereof, can be extended to the nearest AC outlet. Alternate embodiments of receiver means  30  may be powered by battery, or may include battery backup means to supply power to receiver means  30  in the event of a power failure.  
         [0057]    In a preferred embodiment, receiver means  30  is a commercially available BLACK WIDOW receiver unit, or similar units, which may be purchased off-the-shelf from various electronics supply companies such as Whitney Electronics or Holsfelt Electronics. An AC adapter such as that depicted at  26  in FIG. 1 may be used to provide the correct operating voltage for receiver means  30 . In a preferred embodiment of the present invention a BLACK WIDOW RF receiver Model #2.CL manufactured by LCD Co. of California was used as a receiver. FIG. 10 shows a schematic diagram, of a type well understood by those of ordinary skill in the electronics arts, of a receiver unit suitable for use in the present invention.  
         [0058]    Returning to FIG. 1, the system of the present invention may also include a remote control unit  40  which may be purchased from the same source as receiver means  30 . Remote control means  40  controls the operating state of receiver means  30 . That is, remote control means  40  may be used to electronically enable or disable receiver means  30  such that the response of receiver means  30  to the signal transmitted by retractable wire  22  can be controlled. Remote control means  40  preferably includes a panic button which, when depressed or otherwise enabled, transmits a signal which instantly activates the alarm function of receiver means  30 . The means for activating can be a switch  27  which may be operated by hand to cause remote control unit  40  to activate the alarm signal, or to discontinue the alarm signal after it has been activated by either the predetermined signal or the remove control unit  40  itself.  
         [0059]    This feature serves as a “panic” button, i.e., a means of triggering the alarm within receiver means  30  to attract attention or call for aid in the presence of other emergencies. When it is desired to discontinue the alarm signal, switch  27  may be set to a position which causes the previously activated alarm signal to stop. Such remote control units and receivers are well known in the electronic arts and are commonly used in other electronics applications. Accordingly, remote control unit  40  is also readily available from commercial sources and may be purchased and utilized in the system of the present invention “off-the-shelf.” The transmitter circuit of remote control unit  40  may be used as a model for transmitter  4  (FIG. 9) of the movement detector and signal transmitting means  20  of the present invention such that both transmit the proper signal for receiver means  30 .  
         [0060]    This feature may also serve as a means of testing the system  10  to determine its operational status, i.e., ready to operate (or armed), or malfunctioning. If switch  27  is manually set by the operator to a position designed to activate the alarm signal within receiver means  30 , and no alarm signal is produced, a malfunction condition is present. If the alarm signal within receiver means  30  is produced, the system  10  may be considered “armed” or ready to operate.  
         [0061]    Once system  10  is configured as desired, i.e., each movement detecting and signal transmitting means  20  is positioned on a corresponding object whose motion is to be detected, and receiver means  30  is armed, any movement of window  25  or door  24  will cause a predetermined signal to be radiated from movement detecting and signal transmitting means  20  and wirelessly transmitted to receiver means  30 . Receiver means  30  will receive the transmitted predetermined signal and provide an alarm signal in response. In the embodiment shown the alarm signal is an audio signal provided through one or more speakers located within receiver means  30 .  
         [0062]    Turning now to FIG. 2 there is shown a perspective view of movement detecting and signal transmitting means  20 , including casing  31 , switch  33 , retractable wire affixing means  28  and retractable wire  22 . Casing  31  may include an opening  35  for allowing visible light, as from a lamp or an LED  32 , to be seen by the naked eye. The illumination of such a lamp, or light emitting means, gives an operator a visible indication of the operational status of movement detecting and signal transmitting means  20 .  
         [0063]    Casing  32  further includes a slotted opening  41  through which retractable wire  22  and retractable wire affixing means  28  may be disposed. This allows flexibility in positioning retractable wire  22  on an object relative to the position of movement detecting and signal transmitting means  20 .  
         [0064]    [0064]FIG. 3 shows a cross sectional view of the movement detecting and signal transmitting means depicted in FIG. 2, taken along lines  3 - 3  of FIG. 2. Casing  31  surrounds the internal components. The major internal components of movement detecting and signal transmitting means  20  are: an electronic circuit board  52 , a rotatable frame  62  for supporting magnet means  54 , a supporting base means  34  and a rear panel  66 . Rotatable frame  62  includes a channel means  64 , wherein retractable wire means  22  may be disposed, and wrapped around rotatable frame  62 . Also shown is spring means  58  (best illustrated in FIG. 8) for maintaining constant tension on wire means  22  as wire means  22  is pulled closer, or further from casing  31 . The foregoing components are coupled together by pin means  60  (best illustrated in FIGS. 7 and 8).  
         [0065]    As shown in FIG. 4 retractable wire means  22  is in communication at one end with rotatable frame  62 . Rotatable frame  62  includes one or more movable magnets  54 , preferably opposite pole magnets which are spaced from each other and disposed within rotatable frame  62 . The preferred embodiment includes  8  such magnet means  54  spaced equidistantly from each other around rotatable frame  62 . Magnet means  54  may be of a type commonly available commercially from sources such as Radio Shack. One such magnet means suitable for use in a preferred embodiment of the present invention is a common ⅛″ diameter earth magnet available from Radio Shack, part number 64-1895.  
         [0066]    Rotatable frame  62  is preferably a circular supporting frame which is provided with a central opening  70  about which rotatable frame  62  rotates. Rotatable frame  62  is adapted to include a channel  64  for receiving retractable wire  22 . Channel  64  extends about the circumference of rotatable frame  62  and allows retractable wire  22  to be wrapped about rotatable frame  62  in a manner similar to that of a string wrapped around a yo yo. The end of retractable wire  22  is in contact with rotatable frame  62  may be affixed to rotatable frame  62  by traditional means such by knotting the end of retractable wire  22  and inserting it into a notch within channel  64 , or by wrapping and tying one end of retractable wire  22  securely around channel  64 . Retractable wire  22  must be secured such that slippage of retractable wire  22  within channel  64  is avoided. Other means of securing one end of retractable wire  22  within channel  64  will be readily apparent to those skilled in the art.  
         [0067]    Magnet means  54  may be inserted into openings (not shown) in rotatable frame  62  and held in place by means of glue, or other suitable affixing means. The openings into which magnet means  54  are inserted should provide a snug fit for magnet means  54  such that movable magnet means  54  will remain securely in place throughout the life of system  10 .  
         [0068]    [0068]FIGS. 7 and 8 show exploded views from the top and bottom, respectively, of movement detecting and signal transmitting means  20 . As shown in the figures, case  31  and rear panel  66  enclose the components of movement detecting and signal transmitting means  20 . On/off switch  33  provides a means for connecting and disconnecting power from battery  44  from the components residing on electronic circuit board  52 . Battery  44  may be a common  9 V battery of a size suitable for disposition within case  31 . Other battery means, such as miniature batteries, may be utilized to construct smaller embodiments of the present invention. Such means will be readily apparent to those skilled in the art.  
         [0069]    Electronic circuit board  52  includes means  56  for detecting movement of movable magnet means  54 . Means  56  for detecting movement of movable magnet means  54  may be a magnetic field sensor such as a KMZ10B available from Phillips Semiconductors. A schematic diagram of a type readily understood by those skilled in the electronics arts illustrating a preferred circuit connection for means  56  for detecting movement, is provided in FIG. 9.  
         [0070]    The circuit depicted in FIG. 9 operates generally as follows. When the object whose movement is to be detected moves in any direction, retractable wire  22  either extends or retracts (as best depicted in FIG. 1). When the object moves toward movement detecting and signal transmitting means  20 , retractable wire  22  recoils toward movement detecting and signal transmitting means  20 , and vice versa.  
         [0071]    As retractable wire  22  moves, movable magnets  54  rotate. When movable magnet means  54  are displaced from their resting position, a change in the magnetic field surrounding movable magnet means  54 , with respect to magnetic field sensor  56  occurs. FIG. 6 shows two rotatable magnet means  54  in one possible resting position with respect to magnetic field sensor  56 . FIG. 5 shows movable magnet means  54  as they move in direction  45 , as shown by the arrow, past magnetic field sensor  56 . It is the change of the position of movable magnets relative to magnetic field sensor  56  which is detected by magnetic field sensor  56 .  
         [0072]    Returning to FIG. 9, magnetic field sensor  56  senses the change in the magnetic field and provides a signal representing the change, to comparator  1 , in this case a common LM 741. The output of comparator  1  causes relay  2  to energize closing contact  3  and enabling battery power to operate radiating means, i.e., transmitter  4 . The circuitry of transmitter  4  can be any available transmitter configuration known in the art which is capable of transmitting a signal through retractable wire  22  and which can be configured to fit on transmitter circuit board  52 .  
         [0073]    Transmitter  4  generates a predetermined signal which is in turn radiated and wirelessly transmitted to receiver means  30 . In a preferred embodiment, the output of transmitter  4  is coupled to wire means  22 , which serves as a transmit antenna. Retractable wire  22  can be a suitable length of wire, cable, or any other electrically conductive material.  
         [0074]    As will be readily appreciated by those skilled in the art, electronic circuit board  52 , as embodied in the circuit diagram circuit of FIG. 9 has many equivalents. It is not intended that the invention be limited to the particular circuit depicted in FIG. 9.  
         [0075]    Returning now to FIGS. 7 and 8 electronic circuit board  52  may also include a lamp  32  which illustrates when switch  33  is turned to the “on” position and power from battery  44  is applied to the electronic components residing on circuit board  52 . Electronic circuit board  52  is adapted to include openings  47  through which fastening means  43 , which may be conventional screws, are passed as shown.  
         [0076]    Rotatable frame  62 , including retractable wire channel  64  and magnet means  54  is located beneath electronic circuit board  52 . Rotatable frame  62  includes a central opening  70  through which central fastening means  60  is passed. Beneath rotatable frame  62  lies supporting base means  34  which is adapted to include a central threaded opening  72  for receiving the threaded end of central fastening means  60 . Threaded nuts  42  receive fastening means  43 , and act as spacers to hold rotatable frame  62  sufficiently distant from supporting base means  34  to allow rotatable frame  62  to rotate. In this manner circuit board  52 , rotatable frame  62 , and supporting base means  34  are coupled together such that rotatable frame  62  may rotate freely about central fastening means  60 .  
         [0077]    [0077]FIG. 8 shows spring means  58  as it appears coiled around the interior of rotatable frame  62 . Spring means  58  is secured at one end to supporting base means  34  by means of pin  48 . Spring means  58  is thereby positioned to maintain tension on retractable wire means  22 , as rotatable frame  62  rotates. Thus spring means  58  provides the retraction mechanism for retractable wire means  22 .  
         [0078]    In accordance with the portability aspect of the present invention, the above-described structure has been modified as follows. First of all, rear panel  66  of casing  31  (FIGS. 3 and 8) has pressure-sensitive adhesive strips  70  thereon which can be pressed into firm engagement with a window sill or door jamb (FIG. 1) and which will leave no marks when removed. Strips 70 are marketed under the trademark COMMAND of the 3M Company. The 3M COMMAND strips 70 have pressure-sensitive adhesive on both surfaces. One surfaces adheres to rear panel  66  and the other surface adheres to the fixed surface proximate the object whose movement is to be detected. Tabs 80 of strips 70 extend outwardly beyond panel  66  and they do not have any adhesive on their opposite sides. After the panel  66  has been adhesively secured to a surface and it is desired to demount the movement detecting and signal transmitting means  20 , it is merely necessary to grasp each tab 80 and pull it away from panel  66  in the direction of the longitudinal axis of each strip and substantially parallel to the surface of panel  66 . This will release the strips 70 from the surface on which member  20  is mounted and it may also release them from panel  66 . Strips 70 preferably are applied to the rear panel  66  every time the member  20  is to be mounted. Any other suitable pressure-sensitive adhesive may be used. The main objective is that the mounting causes the signal transmitting means  20  be firmly mounted in a manner such that it will not move while mounted but which permits it to be removed so that it can be transported to another location.  
         [0079]    In accordance with the present invention, the retractable wire-affixing means  28   a  of FIG. 11 includes a disc  71  affixed to the outer end of wire  22  and an anchor member in the form of cup member  72  having pressure-sensitive adhesive  73  mounted on its underside which is covered by release paper  74 . Cup member  72  also includes a cover  75  which is connected to cup member  72  by a molded hinge  76 . The cover has a disc-like protrusion  77  having an outer edge which fits in tight engagement with the inner wall  78  of cup-like member  72  when the cover is in a closed position. The cup member  72  is a commercial product sold under the trademark CROWN BOLT of the Crown Bolt, Inc. company of Cerritos, Calif., except that it does not have the pressure-sensitive adhesive thereon, which has been added in accordance with the present invention. It will be appreciated that other types of anchor members can be used instead of a cup member  72 . Such devices may include a small hook or post mounted on a base having pressure-sensitive adhesive thereon in an analogous manner similar to adhesive  73 . Also, as an alternative, disc  28  may have a hole therein so that it is essentially a ring which may be mounted on a simple post having a base with pressure-sensitive adhesive thereon, as noted above. Also, the post may have a bulbous outer end so that it looks like a collar button. Also, if desired, the outer end of wire  22  may be formed in a loop which may be placed on a post or hook. In fact, any suitable arrangement can be used wherein a small unobtrusive member, such as the foregoing anchor members, may be securely fastened to the member whose movement is to be detected and an attachment member may be formed on the end of the wire  22  which can be removably fastened to the small unobtrusive member.  
         [0080]    In use, the cup anchor member  72  is securely adhesively affixed to an object whose movement is to be detected, such as a window or door, as shown by wire-affixing means  28  of FIG. 1, after the release paper  74  has been removed from pressure-sensitive adhesive  73 . Thereafter, while the cover  75  is in the position shown in FIG. 11, the disc  71  at the end of wire  22  is inserted into the cavity of cup  72  and the lid  75  is closed. The other types of anchor members can be used as alternates to the cup anchor member. Thus, the system is in a position to operate as described above.  
         [0081]    When the person who has temporarily used the portable system desires to leave the place where the system has been installed and take the portable system with him, he need merely deactivate the system and thereafter open lid  75  to remove disc  71  and permit wire  22  to retract disc  71  back to a position wherein it abuts the casing  31 . The cylindrical cup  72  is merely left in position on the window or door jamb, and it is substantially unobtrusive inasmuch as its overall diameter is only about ⅜″ and its height is about ¼″. The other types of anchor members described above may also be left where they were adhesively secured to the movable member.  
         [0082]    As noted above, the system of the present invention can be carried in a brief case, purse or overnight case from place to place. In this respect, the total weight of a preferred embodiment is approximately 20 ounces, and it has a volume which occupies a very small portion of a brief case, suitably sized purse or a suitcase.  
         [0083]    While the foregoing portion of the specification has designated wire  22  as being an antenna, it will be appreciated that a suitable antenna may be incorporated within housing  31  and the element  22  may be a suitable high strength string-like member made of suitable plastic or any other suitable material.  
         [0084]    Turning now to FIG. 12, an enhanced version of the movement detecting device and alarm system  10  is shown wherein motion detection information is collected in response to the detection of movement and provided to a remote facility, such as a law enforcement or security agency. FIG. 12 functionally illustrates several of the components discussed above relative to FIGS.  1 - 11 ; namely, the above-described movement detecting and signal transmitting means  20 , the retractable wire  22 , the retractable wire affixing means  28 , and the receiver means  30 . FIG. 12 further illustrates an information gathering device  90  and a remote notification device  92 . Also shown is an optional computer platform  94 . A remote network computer host is further represented at  96 . It will be seen that the remote notification device  92  communicates with the network computer host  96 , either directly or through the optional computer platform  94 , via communication links  98 .  
         [0085]    In preferred embodiments of the invention, as shown in FIG. 13, the information gathering device  90  comprises a D.C. power supply  100 , a camera  102 , an RF transmitter  104 , and an RF receiver  106 . The power supply  100  can be constructed using any suitable constant voltage source, including a rechargeable battery or an AC/DC transformer. A voltage level of 12 Volts should be sufficient to power the information gathering device  90 . The camera  102  preferably has low lumen capability and the ability to capture live video images or sequential still images at a selectable frame rate. The camera  102 , moreover, should be small and unobtrusive. For video images, the camera  102  will typically be an analog device. For still images, the camera  102  can be implemented as a digital device. In that case, the camera will include a memory implemented using a conventional RAM (Random Access Memory) or flash memory chip (or plug-in card). A memory size of about 16 MB (MegaBytes), expandable to 256 MB, should be sufficient for this purpose. The RF transmitter  104  is adapted to transmit image information captured by the camera  102 . If the camera  102  is an analog device, such as an analog video camera, the RF transmitter  104  will transmit analog RF signals. If the camera  102  is a digital device, such as a digital still camera, the RF transmitter  104  will transmit digital RF signals or analog RF signals following digital-to-analog conversion of the camera images.  
         [0086]    It will be appreciated that there are a number of commercially available surveillance products that can be used to implement the power supply  100 , the camera  102  and the RF transmitter  104 . One such product is the Xcam2™ video camera kit available at the www.X10.com Internet website. This product integrates a color analog video camera that can transmit live color video (and audio) signals up to 100 feet, a microphone (for audio signal generation), and a 2.4 GHz. transmitter into a single device of relatively small size.  
         [0087]    The RF receiver  106  can be implemented using the RF receiving circuit components of the previously-described receiver means  30  (see e.g., FIG. 10). It is tuned to receive RF transmissions from the signal transmitting means  20 , and in particular, the predetermined signal sent by the signal transmitting means  20  in response to movement of the retractable wire affixing means  28 .  
         [0088]    The remote notification device  92  can be implemented in several ways according to preferred embodiments of the invention. In one embodiment, shown in FIG. 14A, the computer  94  is used. The remote notification device of this embodiment, designated by reference numeral  92 A, is a unit that includes an RF receiver  112  and a suitable output  110  (e.g., a USB port, serial connector, or other suitable interface) for feeding information received from the information gathering device  90  to the computer  94 . Power may be received from the computer  94  via a suitable power input (not shown), or the device  92 A may include its own power supply  114 . The latter may be a rechargeable battery or an AC/DC transformer. The RF receiver  112  operates at the frequency of the RF transmitter  104  in the information gathering device  90 . It is adapted to receive and process either analog or digital transmissions, depending on the nature of the RF transmitter  104 .  
         [0089]    In the embodiment of FIG. 14A, the computer  94  includes a network interface (e.g., an analog or digital modem, an Ethernet card, or other suitable device) and appropriate control software. In particular, the software must be capable of establishing/maintaining a connection to the remote host  96  and forwarding information thereto that is received from the information gathering device  90 . The XRay Vision Internet Kit™ available at the aforementioned www.X10.com Internet website is one product that can be used to implement the remote notification device  92 A according to the instant embodiment. This product includes an integrated RF receiver and USB converter to capture and manage images received from the X10™ wireless video camera referred to above. Software that is provided with the product is adapted to operate on the computer  94  and forward the images received by the remote notification device  92 A to any suitable remote network host, either in real time if the remote host is so equipped, or via e-mail.  
         [0090]    In a second embodiment of the remote notification device  92 , shown in FIG. 14B, the device, referred to by reference numeral  92 B, is a stand-alone unit that does not require the computer  94 . It includes a D.C. power supply  120 , a memory  122 , an RF receiver  124 , and a network interface  126 . The power supply  120  can be constructed using any suitable constant voltage source, including a rechargeable battery or an AC/DC transformer. A voltage level of 12 Volts should be sufficient to power the remote notification device  92 . The memory  122  can be implemented using a conventional RAM or flash memory chip (or plug-in card). A memory capacity of about 4 to 16 MB, expandable to 256 MB or more, should be sufficient for the remote notification device  92 . The RF receiver  124  operates at the frequency of the RF transmitter  104  in the information gathering device  90 . It is adapted to receive and process either analog or digital transmissions, depending on the nature of the RF transmitter  10 . The network interface  126  can be implemented using a conventional analog modem, a digital modem (e.g., ISDN), or an Ethernet card, any of which are connected or connectable to a data network, such as the public Internet. A wireless interface such as a cellular transmitter/receiver adapted to communicate cellular digital packet data could also be used. The interface might alternatively comprise a Bluetooth or Home RF (e.g. Wi-Fi (IEEE 802.11b)) device that communicates over an air interface with another local device (e.g., a computer or cellular telephone) containing any of the foregoing network interface devices.  
         [0091]    In a third embodiment of the remote notification device  92 , shown in FIG. 14C, the device, referred to by reference numeral  92 C, comprises various functional devices that plug in as modules to a suitable base interface  130 . If the base interface  130  is a computer, the plug-in modules could be implemented as PC or PCMIA cards. Other base interfaces include the DVi family of set top devices from Motorola Corporation. In either case, the plug-in modules could include a memory module  132 , an RF receiver module  134 , and a network interface module  136 . Power for these modules would be typically provided by the base interface  130 . The memory module  132  can be implemented using a conventional RAM or flash memory chip (or plug-in card). A memory capacity of about 4 to 16 MB, expandable to 256 MB or more, should be sufficient for the remote notification device  92 C. The RF receiver module  134  operates at the frequency of the RF transmitter  104  in the information gathering device  90 . It is adapted to receive and process either analog or digital transmissions, depending on the nature of the RF transmitter  104 . The network interface module  136  can be implemented using a conventional analog or digital modem, an Ethernet card, or any other suitable device.  
         [0092]    Referring now to FIG. 15, the operation of information gathering device  90  and the remote notification device  92  will now be described. In step  140 , the information gathering device  90  is notified of a movement event by receiving (at the RF receiver  106 ) a predetermined signal from the movement detecting and signal transmitting means  20 . The information gathering device then activates its camera  102  to begin acquiring pictures in step  142 . The camera  102  is preferably aimed at the vicinity of the retractable wire affixing means  28 , such that the cause of the movement will be viewable. In step  144 , the RF transmitter  104  begins sending image information to the remote notification device  92 . If the information gathering device also includes a microphone, the RF transmitter  104  will also send audio information to the remote notification device  92 .  
         [0093]    In step  146 , the remote notification device  92  receives the information transmitted by the information gathering device at its RF receiver  106 / 112 / 124  (see FIGS. 14A, 14B, and  14 C, respectively). If the remote notification device is implemented according to FIG. 14A, it forwards the received information to the computer  94  in step  148 A. The computer  94  then establishes a network connection, as necessary, and forwards the information to the remote host  96  in step  150 A. If the remote notification device is implemented according to FIGS. 14B or  14 C, it buffers the received information in its memory  122 / 132  in step  148 B. In step  150 B, the remote notification device establishes a network connection, as necessary, and forwards the information to the remote host  96 .  
         [0094]    The remote host  96  can be implemented as an Internet host that responds to the information received from the remote notification device  92  as either an information processing point or a store-and-retrieval point. For example, the host  96  might be a server at a security agency that displays the received information on a monitor for viewing by a security agent. Alternatively, the information could be forwarded, via email or the like, to the owner of the premises where the system  10  is located, or elsewhere. Still further, the host  96  might itself be an email server that receives the information from the remote notification device  92  as an attachment to an email addressed to the owner of the premises under surveillance, or elsewhere.  
         [0095]    Turning now to FIGS.  16 - 20 , an optional aspect of the invention will be described that allows object identification information to be provided locally and/or remotely to a designated location, such as a subscriber&#39;s forwarding telephone number, a law enforcement agency, or a security agency. In this way, when a subscriber&#39;s movement detecting and signal transmitting means  20  is triggered, a meaningful description of the object to which the device was attached can be provided.  
         [0096]    In FIG. 16, the motion sensing and transmitting means  20  of FIG. 9 is shown with additional components that allow it to store a unique identifier, such as a digital code word, and then wirelessly transmit the identifier to the receiver means  30  (see FIG. 1) whenever the object whose movement is to be detected is displaced from a predetermined position. In the exemplary design of FIG. 16, the unique identifier is stored in a data store  200  of suitable size. By way of example only, the data store  200  can be implemented using a flash ROM or RAM memory chip (or plug-in card) whose size is based on the required size of the unique identifier. For example, if the unique identifier is a product serial number comprising “n” ASCII characters, the data store can be implemented as an “n×8” memory array, as an “n/2×16” memory array, as an “n/4×32” memory array, and so on. Note that the term “unique identifier” does not necessarily require that the identifier be unique relative all other motion sensing and transmitting means  20  owned by all subscribers. Rather, in view of certain programmability features described in more detail below, the unique identifier need only be unique with respect to the motion sensing and transmitting means  20  owned by one subscriber.  
         [0097]    Closure of the switch  3  (as a result of displacement of the object whose movement is to be detected) activates the transmitter  4  and also provides a sense input to a control logic circuit  202 . The latter can be implemented in fairly straightforward fashion as a data selector with clocking to facilitate selective (e.g., sequential) output from one or more array locations in the data store  200 . Alternatively, to provide a more feature-rich design, the logic circuit  202  could be implemented as a programmable processor. In that event, the data store  200  will preferably contain the processor&#39;s control programming code in addition to the unique identifier. A programmable processor implementation of the logic circuit  202  would also facilitate the implementation of other useful functions in the motion sensing and transmitting means  20 , such as the ability to control the device from the receiver means  30  or some other remote location. Thus, assuming a radio receiver  206  (see FIG. 16) is added to the motion sensing and transmitting means  20 , or combined with the radio transmitter  4  as a transceiver, the control logic  202  could be remotely programmed via radio control to facilitate a variety of operations, such as polling the device to determine operating conditions, battery states or other useful information, and programming the device to set and/or reset its various operational characteristics.  
         [0098]    When the control circuit  202  is activated upon closure of the switch  3 , the unique identifier in the data store  200  is transferred to a D/A (Digital-to-Analog) converter  204  and converted to a corresponding analog signal. The analog signal is used to modulate the RF output of the transmitter  4  (see FIG. 9), such that the unique identifier is wirelessly transmitted to the receiver means  30  as an encoded RF signal. Alternatively, the unique identifier could be transmitted in digital form without D/A conversion.  
         [0099]    In FIG. 17, the receiver means  30  of FIG. 10 is shown with additional components that allow it to process the encoded RF signal received from the motion sensing and transmitting means  20  and convert it to digital form (as necessary) to recover the unique identifier. The unique identifier is then processed (either locally, remotely or both) for conversion to object identification information identifying the object to which the motion sensing and transmitting means  20  is attached. Regardless of where the unique identifier is converted, the object identification information can be output locally at the receiver means and/or it can be provided remotely to a forwarding telephone number designated by the subscriber, or to another location such as a law enforcement or security agency.  
         [0100]    In the exemplary design of FIG. 17, the receiver means  30  includes the antenna and the receiver of FIG. 10. The receiver is tuned to the frequency of the transmitter  4  in the motion sensing and transmitting means  20 . It demodulates the encoded RF signal. If the unique identifier is received in analog form, it is forwarded to an A/D (Analog-to-Digital) converter  220  for conversion to digital form. The unique identifier is then provided to a control logic circuit  222 . The control logic circuit  222  is preferably implemented as a programmable processor that is associated with a related data store  224  that contains programming code for the control logic circuit. The data store  224  can be implemented using a conventional memory component, such as a flash ROM or RAM memory chip (or plug-in card) whose size is minimally based on the required size of the programming code.  
         [0101]    The memory used for the data store  224  may further contain an optional look-up table  226  if it is desired that the receiver means  30  convert the unique identifier locally into object identification information. An exemplary implementation of the look-up table  226  is shown in FIG. 18. This implementation features one or more row entries  228  for matching the unique identifier received from the motion sensing and transmitting means  20  with a descriptive word or phrase. Each entry  228  comprises a data set that contains a unique identifier field  230  and a descriptive word or phrase field  232 .  
         [0102]    By searching the unique identifier field  230  for an entry that matches the unique identifier received from the motion sensing and transmitting means  20 , the control logic circuit  222  can rapidly correlate the unique identifier with a descriptive word or phrase that identifies the object to which the movement detecting and signal transmitting means  20  is attached. As shown in FIG. 17, the control logic circuit  222  can then output this information locally in visual form to a visual display device  234  (e.g., an LCD), or audibly to a speech synthesizer (e.g. wavetable) device  236 , or both. This will permit a person who is physically present within visible or audible range of the receiver means  30  to promptly determine the location of the motion sensing and transmitting means  20  that set off the alarm system  10 .  
         [0103]    The control logic circuit  222  can also be implemented to forward the unique identifier received from the motion sensing and transmitting means  20  as part of an alarm alert to a remote security administration system (not shown in FIG. 17) so that an object identification look-up can be performed remotely. As described in more detail below, the security administration system can be programmed to respond to the alarm by sending an alert to a subscriber-designated contact location (e.g., a forwarding telephone number), advising that the alarm system  10  has been triggered and specifying the location of the motion sensing and transmitting means  20  that triggered the alert. Additionally, or in the alternative, the security administration system can download the object identification information to the receiver means  30  for output via the visual display device  234  or the speech synthesizer  236 . This feature could be used in implementations where the receiver means  30  does not perform local conversion of the unique identifier to object identification information.  
         [0104]    A modem  238  in the receiver means  30  can be used for transmittal of the unique identifier via a telephone line to a remote computer host implementing the security administration system. Alternatively, the receiver means  30  could be equipped with a data network interface for connection to the remote computer host via a computer data network, such as the global Internet. The connection could further include any of a cable interface, an Ethernet interface, a radio/cellular interface, etc. that physically interconnects the receiver means  30  to the remote computer host.  
         [0105]    [0105]FIG. 19 is a flow diagram showing operational steps performed by the control logic circuit  222  of the receiver means  30  in an exemplary embodiment in which the unique identifier is transmitted to the security administration system for remote conversion to object identification information. Beginning in step  240 , the control logic circuit  222  is placed in a listening mode to await input from one or more motion sensing and transmitting means  20  within RF transmission range. In step  242 , the control logic circuit  222  waits for input from the one or more motion sensing and transmitting means  20 . If such input is received, indicating that one of the motion sensing and transmitting means  20  has been disturbed, an audible alarm is sounded in step  244  via the circuitry of FIG. 10. In step  246 , the modem  220  establishes a connection with the remote computer host. In step  248 , the unique identifier is fed to the modem  220  and transmitted to the security administration system. A stored subscriber authentication code is preferably also sent (in advance of sending the unique identifier), so that the receiver means  30  can be identified and validated. The security administration system may then optionally return object identification information if the receiver means  30  is adapted to locally display such information. Otherwise, such information is not returned by the security administration system. In step  250 , the modem  220  disconnects from the remote computer host. In step  252 , the control logic circuit  222  waits for a reset signal, e.g., from the remote control unit  40  (see FIG. 1). When the reset signal is received, the audible alarm is shut off and the receiver means  30  is reset to standby mode in step  254 .  
         [0106]    In FIG. 20, an exemplary security administration system  260  as described above is shown. The security administration system  260  includes a computer host  261  and a modem pool  262  containing plural modems that allow simultaneous connections with multiple alarm systems  10  associated with multiple subscribers. Although not shown, the security administration system  260  may also include a data network interface for communicating with multiple alarm systems  10  via a computer data network, such as the public Internet.  
         [0107]    There is also connected to the computer host  261  a large capacity data storage resource  264  (such as a storage array, a storage network, etc.) that stores a subscription database containing subscriber information for multiple subscribers. The subscription information includes data sets that correlate the unique identifiers associated with each subscriber&#39;s motion sensing and transmitting means  20  with object identification information specified by the subscriber. The subscription information preferably further includes contact information for use in forwarding the object identification information.  
         [0108]    The computer host  261  further includes a memory  266  that stores a security monitoring control program  267  for implementing the functionality required to receive and respond to incoming alarm alerts from the receiver means  30  of the multiple alarm systems  10 . In addition, the memory  266  preferably further stores a subscriber registration and provisioning program  268  that allows subscribers to register for security service and provision user-specified object identification information to be associated with the unique identifiers associated with their motion sensing and transmitting means  20 . Subscribers are also able to provision contact information that allows the security administration system  260  to contact them in the event of a security breach.  
         [0109]    [0109]FIG. 21 is a flow diagram showing operation of an exemplary implementation of the security administration system  260  in response to an alarm alert sent from a receiver means  30 . Beginning in step  270 , the security administration system  260  receives a modem call from a subscriber&#39;s receiver means  30 . In step  272 , the computer host  261  receives a data burst from the receiver means  30 . The data burst includes an authentication code identifying the receiver means  30  and a unique identifier corresponding to the movement detecting and signal transmitting means  20  that was triggered. In step  274 , an authentication evaluation is made. If the receiver means  30  fails the authentication test, the authentication code can be sent to an administrator in step  276  for verification. If the receiver means  30  passes authentication, the computer host  261  retrieves the subscriber&#39;s subscription information in step  278  from the subscription database of the data storage resource  264 . In step  280 , the computer host  261  matches the unique identifier received in the data burst with the corresponding object identification information provisioned by the subscriber. In step  282 , the computer host  261  obtains the subscriber&#39;s contact information. This could be a forwarding location associated with the subscriber, such as a voice telephone number, a facsimile telephone number, an email address, an IRC (Internet Relay Chat) address, or otherwise. The forwarding location could also be a law enforcement or security agency. Moreover, as stated above, the forwarding location could also be the receiver means  30  itself if local output of the object identification information is desired.  
         [0110]    The computer host  261  then initiates a security alert sequence based on the subscriber&#39;s contact information. This sequence includes step  284  in which communication is established as necessary to the forwarding location and step  286  in which the object identification information corresponding to the activated movement detecting and signal transmitting means  20  is delivered. For example, if the forwarding location is a voice telephone number, the object identification information can be delivered as a live or synthesized voice message. For telephone, IRC, email or any other interactive media, the computer host  261  can prompt and hold for a response. For a telephone, the computer host  261  can prompt and hold for a response that represents the call recipient pressing various buttons on his or her telephone in order to connect to a designated emergency service agency or other entity. For example, the number “1” could be used to connect the call recipient to a police department, the number “2” could be used to connect the call recipient to a fire department, and the number “3” could be used to place a custom call. Some other number, such as the number “4,” could be used to reset the alarm via the computer host  261 .  
         [0111]    If the forwarding location is a telephone or facsimile number, the object identification information can be transmitted via the public switched telephone network to a remote telephone or facsimile machine. If the forwarding location is an email or IRC address, the object identification information can be transmitted via a data network for delivery to a remote computer host. If the forwarding location is the receiver means  30 , the object identification information can be transmitted via the modem pool  262  to the receiver means.  
         [0112]    Following delivery of the object identification information, the remote computer host  260  terminates the security alert sequence in step  288 . This step preferably includes logging the date and time of the security alert into the subscriber&#39;s account records, along with the object identification information. The logging operation can be used to create a security record and also for billing purposes.  
         [0113]    As a result of the security alert sent by the security administration system  260 , the subscriber will be provided with very specific information about the nature of the security breach. In particular, because the object identification information is provisioned by the subscriber, it can be personalized in a way that allows the subscriber to gauge their response to the security alert according to the information provided. For example, a young mother on a warm summer day may wish to attach one movement detecting and signal transmitting means  20  to the baby&#39;s crib during nap time, and another movement detecting and signal transmitting means  20  to a partially open window in the baby&#39;s room. Upon receipt of the security alert, the mother will know from the object identification information that the alert is either the result of the baby waking up and jostling the crib or a potentially serious security breach due to an intruder attempting to raise the baby&#39;s window.  
         [0114]    As will now be described with reference to the flow diagram of FIG. 22, it is very simple for a subscriber to provision each of their movement detecting and signal transmitting means  20  as these devices are attached to different objects. A network-attached computing device and a few moments of time to fill in an online form are all that is required. In step  290  of the provisioning process, the subscriber initiates contact with the computer host  261  and the latter establishes a communication session. In step  292 , the computer host  260  prompts the subscriber for registration information (e.g., user name and password) if they have an existing account, or to set up a new account if the subscriber is not yet registered. If, in step  294 , the subscriber indicates that they need to set up a new account, the computer host  261  engages the subscriber in an account setup dialog in step  296 . This will establish a record of such information as the subscriber&#39;s name, billing address, login name, password, and an authentication identifier associated with the subscriber&#39;s receiver means  30 . The subscriber will preferably also be requested to accept a subscription agreement. The computer host  261  will then create one or more account records in the subscriber database of the data storage resource  264 , and if necessary, reserve storage space for the subscriber&#39;s provisioning information.  
         [0115]    Following registration in step  296 , or if the subscriber previously provided a registration number in step  292 , the computer host  261  initiates a provisioning session in step  298 . The provisioning session can be implemented in a variety of ways, but preferably involves the subscriber filling in fields in an on-line graphical form. Thus, in step  300 , the computer host  260  presents the subscriber with a web page or the like containing a listing of one or more movement detecting and signal transmitting means  20  that can be provisioned. Each line of the listing will include a field specifying the unique identifier associated with the movement detecting and signal transmitting means  20 , and a field containing the device&#39;s object identification information. When the subscriber first registers for service, the listing will be blank. For registered subscribers who have previously provisioned their movement detecting and signal transmitting means  20 , the listing will show the subscriber&#39;s current provisioning information. The subscriber then updates the listing as to suit their current needs.  
         [0116]    In step  302 , the subscriber signifies that they have finished updating their provisioning information by submitting the online form. The computer host  261  then implements a CGI script or the like to process the form information in step  304  and update the subscriber&#39;s database information. Thereafter, the computer host  261  can terminate the provisioning session in step  306 . Alternatively, an optional step  308  can first be performed in which the computer host  261  initiates a communication session with the subscriber&#39;s receiver means  30 . The purpose of this session is to download the subscriber&#39;s provisioning information to the look-up table  226  in the receiver means  30  so that local conversion of unique identifiers to object identification information can be performed.  
         [0117]    It will be appreciated that step  308  could be eliminated in implementations of the alarm system  10  where the receiver means  30  is configured to allow the subscriber to provision the look-up table  226  by hand. In particular, the receiver means  30  could be provided with a data entry interface, such as a keypad and a display (not shown), that allows the subscriber to program object identification information into the look-up table  226  (see FIG. 17) via the control logic  222 . The receiver means  30  could also be provided with an audio recording system (not shown) that allows the subscriber to record object identification information as a series of audio messages that are each associated with a unique identifier in the look-up table  226 .  
         [0118]    Having now described various security functions of the alarm system set forth in the various embodiments above, it is important to note that the alarm system could be adapted for additional purposes, such as industrial process monitoring and measurements. This functionality could be provided by modifying the movement detecting and signal transmitting means  20  so that it produces an output indicating a distance that the retractable wire means  22  moves relative to the movement detecting and signal transmitting means  20  once the device has been set (see FIG. 1). This measurement feature could be for such functions as industrial tank expansion measurement, and the like. The measurement feature could be readily implemented with relatively minimal modification of the movement detecting and signal transmitting means  20 . For example, the field sensor  56  and the closing contact  3  of FIGS.  7 - 9  could be implemented as a reed switch that will open and close as the magnets  54  pass by. Either the control logic  202  of the movement detecting and signal transmitting means  20  or the control logic  222  of the receiver means  30  can be programmed to count the number of pulses represented by each magnet  54  passing by the field sensor  56 . Each pulse would be associated with a distance that the retractable wire means  22  moves relative to the movement detecting and signal transmitting means  20 . The total number of pulses would thus correspond to the total distance moved. The distance could be reset to zero when the movement detecting and signal transmitting means  20  is set, following which distance monitoring would begin. Another implementation option would be to use optical counting by installing an optical source/detector pair in the movement detecting and signal transmitting means  20  and an optical signal modulator. The optical signal modulator could be an optical medium that is encoded with alternating light/dark bars, bar codes, etc. and which moves relative to the source/detector pair in response to motion of the retractable wire means  22 , so as to thereby modulate the optical signal. The components used in a computer mouse pointing device represent one optical technology that could be used. The measurement information can be output locally by the receiver means  30  in audible or visual form, or it can be sent to a remote location using any of the communication modalities discussed above, including telephone, network, cable, radio/cellular communication, etc. Once the receiver means  30  outputs its message to the remote location, the remote location can respond to the message in various ways, including (1) massaging response instructions back to the receiver means  30  for forwarding to the signalling movement detecting and signal transmitting means  20  or any of its counterparts, (2) forwarding a customized message to a designated forwarding location, (3) taking any other appropriate action.  
         [0119]    It should further be noted that a process measuring implementation of the invention may require consideration of environmental factors that lead to a change in the materials used to construct the various components of the alarm system. For example, it may be desirable to water-proof the movement detecting and signal transmitting means  20  for outdoor use. Similarly, will be understood that the retractable wire means  22  can be made from a variety of materials, including thread or string, synthetic line (e.g. fishing line), or more durable materials such as steel, tungsten, or the like for high heat use.  
         [0120]    While the invention has been described in conjunction with various embodiments, they are illustrative only. Accordingly, many alternatives, modifications and variations will be apparent to persons skilled in the art in light of the foregoing detailed description. The foregoing description is intended to embrace all such alternatives and variations falling with the spirit and broad scope of the appended claims and their equivalents.
