CLAIM OF PRIORITY 
       [0001]    This application claims priority to U.S. Provisional Application 61/207,540 filed Feb. 13, 2009, U.S. Provisional Application 61/281,096 filed Nov. 12, 2009 and US Design Application 29/354,639 filed Jan. 27, 2010, the contents of which are fully incorporated herein by reference. 
     
    
     FIELD OF THE INVENTION 
       [0002]    The invention relates to an infant supervision device, in particular, to an infant theft prevention device. 
       BACKGROUND OF THE INVENTION 
       [0003]    The invention relates to a surveillance system preferably for tracking and preventing theft of infants and newborns at neonatal facilities. Infant abduction from hospitals remains an ever present threat, forcing infant care facilities to implement elaborate anti-theft safeguards that range from staffing additional nursing and security personal to installing sophisticated surveillance equipment, such as electronic tags, motion sensors and closed circuit cameras. Additionally, most locations have implemented a form of label matching technique, where all authorized individuals, including the parents, possess a randomly generated number, typically on their wrist band, which matches the random number on an infant&#39;s ankle or wrist band. All of the techniques mentioned above are well known in the art. 
         [0004]    However, despite the much improved state of theft detection and prevention, abductions still occur. One of the weaknesses of the presently available systems is that they are highly noticeable and readily perceptible as security devices. A thief&#39;s best strategy may be to alertly and quickly be able to perceive an apparent anti-theft system or procedure. Advance notice or awareness may give a thief the time and opportunity to plan or implement a circumventive technique. 
         [0005]    The present invention attempts to address this problem by taking a device that is presently being used for the medicinal needs of an infant, and enhancing it by adding integrated and discrete security features that are not readily perceived, and once perceived are difficult to circumvent. Specifically, the present invention accomplishes this by adding security features to the umbilical cord clamp of a newborn., which will not be removed for any routine treatment by hospital personal since it is needed to prevent bleeding and infections of the navel and abdominal area of an infant. Therefore, its unauthorized or unexpected removal will immediately raise an alarm with the nursing and security staffs. For this reason also, a thief, who likely desires to keep an infant alive and healthy, will be reluctant to remove the present invention, or will replace it with an umbilical cord clamp of his or her own. In any event, once the present invention is attached to the umbilical cord or its stump, it cannot be removed without cutting or otherwise breaching the claimed device. Such tampering will set off an external sensor, which may also be capable of locating the breached device. The external sensor will also be able to detect whether someone is trying to remove an infant from the care facility while the infant is still wearing the claimed device. 
       DESCRIPTION OF THE RELATED ART 
       [0006]    U.S. Pat. No. 4,899,134 discloses a detectable element inconspicuously disposed in an umbilical cord clamp used to clamp the umbilical cord a newborn child allows the detection of unauthorized movement of the newborn child and prevents the possible abduction of the newborn child. 
         [0007]    U.S. Pat. No. 5,006,830 teaches a method and device for deterring unauthorized removal of a newborn from a defined area has a locking umbilical clamp with an attached identification mark and an attached triggering device capable of triggering a detection system upon removal of the umbilical clamp from the defined area and a wristband with an identification mark thereon corresponding to the identification mark on the umbilical clamp for attachment to the wrist of a person authorized to remove the newborn from the defined area. 
         [0008]    U.S. Pat. No. 6,144,303 concerns a tag for monitoring the security of a patient, the tag comprising, a housing having a wall, the wall having an inner surface and an outer surface, an electronic circuit located in the housing, the electronic circuit including an alarm circuit, including a capacitance measuring circuit, the capacitance measuring circuit having first and second electrodes, the first and second electrodes located adjacent the inner surface and in spaced relation from one another to form a capacitor, the alarm circuit having means for generating an alarm signal upon the capacitance measuring circuit detecting a level of capacitance corresponding to an alarm condition, whereby the outer surface of the housing is placed in contact with the patient, with the first and second electrodes capacitively coupled to the patient, but without the first and second electrodes in physical contact with the patient, the capacitance measuring circuit detects an alarm condition when the patient is no longer in contact with the outer surface of the tag. 
         [0009]    U.S. Pat. No. 6,753,781 discloses, in one aspect of the invention, a dual-mode infrared/radio frequency (IR/RF) transmitter is secured within a wristband worn by the mother and within an ankle and/or wristband worn by the infant. In a matching mode of operation, IR signals are received by infrared receivers located within the various rooms of the hospital to precisely and automatically determine by proximity that mother and infant arc correctly united. In a presence detecting mode, RF signals from the infant&#39;s badge are detected by RF receivers located throughout the maternity ward of the hospital or throughout the hospital generally. It a security mode, RF receivers located proximate exits of either of the maternity ward and/or the hospital detect RF signals from the ankle and provide a signal to generate an alarm. 
         [0010]    Various implements are known in the art, but fail to address all of the problems solved by the invention described herein. One embodiment of this invention is illustrated in the accompanying drawings and will be described in more detail herein below. 
       SUMMARY OF THE INVENTION 
       [0011]    The present invention relates to an infant supervision device featuring an umbilical cord clamp having a hinge, jaws and a locking mechanism.

     DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0028]    The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals. 
         [0029]    Reference will now be made in detail to embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto. 
         [0030]      FIG. 1  shows a clamp  10 , clamp top  12 , clamp bottom  13 , a first end  30 , a second end  40 , serrated edge  50 , a first jaw  51 , a second jaw  52 , a hinge  60 , a dimple opening  62 , an inner hinge  63 , an opening  65 , a locking mechanism  69 , a first locking mechanism  70 , an additional locking mechanism  72 , a clasp  73 , V shaped hooks  73   b,  a latch  74 , inwardly facing hooks  74   a,  a gap  74   b,  a recessed opening  74   c,  a hook  75 , a catch  76 , a wire  110 , a first terminal  111 , a second terminal  112 , sensor  113 , and a sleeve  130 . 
         [0031]    The clamp  10  functions as a conventional umbilical cord clamp and as a security device. The clamp  10  may be manufactured with the jaws  51  and  52  as an integral device or they may be fused together during manufacturing. The serrated edge  50  is placed around the umbilical cord of a newborn infant just before the umbilical cord is cut off from the placenta and is used to stop the bleeding and prevent infection in the remaining stump. The opening  65  is optional and is present as a backward compatibility feature, to accommodate the presently available wire or plug sensors (not shown). The opening  65  may be used to store the present invention on a ring threaded through the opening  65 . 
         [0032]    The hinge  60  and the inner hinge  63  are shown in an embodiment where the present invention is made as a sleeve  130  over a conventionally available clamp. Alternatively, only a single hinge  60  may be included together with an optional opening  65 . If an opening  65  is not present it is still preferable to have the dimple opening  62  for a tighter locking of the jaws  51  and  52 . The jaws  51  and  52  rotate around both the inner hinge  63  and the hinge  60 . Although the hinge is shown as a specific configuration, this is for illustrative purposes and any type of hinge device may be employed. 
         [0033]    The sensor  113  can be removable or permanently attached to the present invention and is preferably placed on the second end  40  of the clamp  10 . In this configuration it blends in with the locking mechanism  70 , and is not obstructing other functionalities of the clamp  10 . The preferred method of closing the present invention is a locking mechanism  69  that locks permanently, such as the first locking mechanism  70  together with an additional locking mechanism  72 , both located substantially at the second end  40 . The number and complexity of various locking mechanisms and features may vary as long as there is at least one locking mechanism  70  that achieves a permanent coupling. 
         [0034]    Still referring to  FIG. 1 , the locking mechanism  69  is shown having a first locking mechanism  70  and an additional locking mechanism  72 . The first locking mechanism  70  has a clasp  73 , shown as a two opposite facing V shaped hooks  73   b,  and a latch  74 , shown as two inwardly facing hooks  74   a  on either side of a gap  74   c.  To operate this closing mechanism  70 , V shaped hooks  73   a  are forced into the gap  74   c  between the inwardly facing hooks  74   a.  The V shaped hooks  73   a  are strongly biased to take a V shape form. To get past the inwardly facing hooks  74   a,  the V shaped hooks  73   a  are forced together and then snap back into the shape of a V once permanently encased inside the recessed space  74   b.  The recessed space  74   b  does not afford any movement by V shaped hooks  73   a,  and the contour of the inwardly facing hooks  74   a  and of the V shaped hooks  73   b  is uniformly interlocking and snug, reinforcing the locking mechanism  69 . 
         [0035]    To further enhance the permanent nature of the locking mechanism  69 , the opening  74   c  and the recessed space  74   b  may be enclosed by a side wall  15  ( FIGS. 4 &amp; 5 ) on both sides, which may or may not have additional inwardly facing hooks. A side wall  15  would completely block any access to the V shaped hooks  73   b,  once these are inside the recessed space  74   b.  If sidewalls have additional inwardly facing hooks  74   a,  the clasp  73  may have additional corresponding V shaped hooks  73   a.  These, together with the V shaped hooks  73   a  that are shown would then form an inverted tip of a spike, while the gap  74   c  with additional inwardly facing hooks  74   a  would form an opening with inwardly facing flaps. 
         [0036]    The additional locking mechanism  72  has a hook  75  and a catch  76  and may provide a supplemental locking strength to the present invention. One skilled in the art will appreciate that other embodiments of permanent locking means are possible and may be used to enable to present invention. 
         [0037]    The placement of the latch  74  and the clasp  73  is variable and either may be disposed on the first jaw  51  or on the second jaw  52 . Once the clamp  10  is attached and locked around an umbilical cord or an umbilical stump of an infant, the serrated edge  50  makes it virtually impossible to remove it by either sliding the jaws  51  and  52  off the umbilical cord or stump or by opening up the locked mechanism  69 , without having to cut the clamp  10 . The serrated edge  50 , although illustrated as serrated, may be other shapes. The edge may be any shape or functionality that achieves the desired purpose, such as, but not limited to, a flat surface, or an interlocking surface using any shape or pattern. 
         [0038]    Still referring to  FIG. 1 , the sensor  113  may be located at the second end  40 , as shown, or anywhere else throughout the clamp  10 . The sensor  113 , the first and second terminals  111  and  112 , together with the wire  110  form the preferred integrated circuitry that enables the present invention to function as an active or passive security device. The wire  110  is discretely enclosed or embedded within the entire length of the first jaw  51 , the second jaw  52 , the hinge  60 , the sensor  113 , and within the first and second terminals  111  and  112 . The sensor  113  contains a power source  120  (shown in later figs.) which may preferably be a battery, such as but not limited to a long life Lithium or Zink miniature battery, common in wrist watches and other small electronic devices. Alternatively, the power source  120  may be a rechargeable battery, such as but not limited to a nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), or lithium ion polymer (Li-ion polymer), in which case, the clamp  10  would include a charging terminal (not shown) that would connect to a charging device. 
         [0039]      FIG. 2  discloses the clamp  10  shown in  FIG. 1  in a closed position with the current now flowing along the wire  110 , along the first and second jaws  51  and  52 , the hinge  60 , through the first terminal  111  and the second terminal  112 , and into the sensor  113 . Also shown in this figure are a first end  30 , a second end  40 , a clamp top  12 , a clamp bottom  13 , a serrated edge  50 , a dimple opening  62 , an opening  65 , a clamp locking mechanism  69 , having a first locking mechanism  70 , an additional locking mechanism  72 , a clasp  73 , V shaped hooks  73   b,  a latch  74 , inwardly facing hooks  74   a,  a gap  74   b,  a recessed opening  74   c,  a hook  75 , a catch  76 . The clamp locking mechanism is preferably disposable, but may be reuseable. 
         [0040]    In an embodiment where the sensor  113  is a magnet, or rather contains an electromagnet, the current that flows through the wire  110  and into the sensor  113 , would be wrapped around a segment or a plug of material capable of becoming a magnet. When the clamp  10  is closed, the magnetic field created by such a magnet causes a small amount of current to flow within the external detection device. This current flow within the external detection device is then detected as an intact clamp  10 . If the clamp is cut during a security incident the sudden disappearance of this electrical current may trigger an alarm or other alerts. If a thief attempts to leave without removing the clamp  10 , a set of sensor gates at entrances and exits will be able to detect a strong magnetic field passing within a close proximity, and trigger an alarm. 
         [0041]    The sleeve  130  surrounds the first jaw  51  and the second jaw  52 , as well as the inner hinge  63  and the first locking mechanism  70 . It preferably affords resistance to tampering with the clamp  10 . The sleeve  130  may be manufactured from any material, but preferably from a polymer, including but not limited to, plastic, silicone, or another hard, non-brittle polymer, or a vinyl polymer, such as PVC, or any other type of strong polymer. All materials used may be additionally tempered or reinforced. The sleeve  130  may also be manufactured out of a metal alloy that is non-conducting and non-oxidizing so as to avoid interference with various security devices and medical equipment, and to avoid exposing infants or others to by-products of oxidation, which may be toxic. A specific material used may additionally be non-magnetic and fire retardant. A material having memory may be utilized, so as to alert medical or security staff of any attempted tampering, for example, some plastics may begin to fragment into fibers that are difficult to remove or acquire scratches and other easily perceived signs of damage. The materials for the first and second jaws  51  and  52  may be any material, but should be preferably hypoallergenic, with plastic being the commonly used material. 
         [0042]      FIGS. 3-5  show an alternative embodiment of the present invention. Shown are a clamp  10 , a clamp top  12 , a clamp bottom  13 , an enlarged section  14 , sidewalls  15 , a cover  16 , a sensor dish  17 , a first end  30 , a second end  40 , a large section  45 , a small section  47 ,  45  &amp;  47  look the same size a first jaw  51 , a second jaw  52 , a hinge  60 , a dimple opening  62 , an inner hinge  63 , an opening  65 , an additional locking mechanism  72 , a hook  75 , a catch  76 , sensor  113 , a power source  120 , a circuit board  122 , a sleeve  130 , a receiver  140 , a transmitter  150 , and a memory chip  152 . In this embodiment the first and second jaws  51  and  52  form the small section  47 , whereas the cover  16  and dish  17  that contain and cover the sensor  113  form the large section  45 . Note that the clamp top  12  is shaped in a way that is convenient for pressing by a human finger. The dimensions of the small section  47  for alternative and preferred embodiments are preferably between 0.3 and 0.5 of an inch in height and between 0.24 and 0.34 of an inch in width. The dimensions of the large section  45  for alternative and preferred embodiments may be between 0.6 and 0.91 of an inch high with the diameter of the enlarge section between 0.5 and 1 inch in width. The overall length of the clamp  10  may be between 2 and 4 inches. The appearance of the clamp  10  or of the large and small sections  45  and  47  may be varied. The clamp  10 , may be substantially straight without any pronounced curves or sectional bending. 
         [0043]    In  FIGS. 3-5 , only the additional locking mechanism  72  is shown, (the clamp locking mechanism  70  is not shown) and may serve as the primary locking mechanism  69  for this particular embodiment. Alternatively a first locking mechanism  70  may have been used instead. Additionally, the locking mechanism  69  may be enhanced by a magnetic locking mechanism that would attract the cover  16  to the sensor dish  17 . This magnet may be activated when the clamp  10  is closed, with the current flowing through the closed circuit via the wire  110  and terminals  111  and  112  (not shown in this figure). In this embodiment the sidewall  15  surrounds the dish  17  and either conceals the additional locking mechanism  72  entirely, or forms a catch  76 . 
         [0044]    The sensor  113  may transmit and/or receive a variety of signal types such as, but not limited to radio frequency identification (RFID), ultrasound identification (USID), wireless network signals or (Wi-Fi), microwaves, or an electric current from a strong magnetic field. The type of signal transmitted or received directly impacts the type of an external detection device that may be used with the present invention. In the present invention, the clamp  10  may begin emitting signals or other types of electromagnetic radiation, as soon as the clamp  10  closes and the first terminal  111  and the second terminal  112  are in physical connection with each other. Thus the closing of the locking mechanism  69  enables the direct current from the power source to flow through the wire  110  and provide power to the other components of the sensor  113 . 
         [0045]    In an embodiment where the sensor  113  is an RFID device, the external detection device will need to be able to transmit, receive and interpret radio signals. The sensor  113  would typically have an internal memory chip  152 , that can be written to once or many times. The memory chip  152  may be the same no matter what type of electromagnetic radiation is being processed by the sensor  113 . The external detection device would obtain all information contained on this internal memory chip  152 , once the sensor  113  and the external detection device have an established communication. This information may include, but is not limited to, a unique identifier of the particular clamp  110 . In security records of the infant care facility this unique identifier will likely associated with a particular infant carrying this particular clamp  10 . Additionally the sensor  113  may be able to detect an infant&#39;s body temperature and communicate this information to the external detection device  170 . This may be important in helping to prevent SIDS. For example, a sudden drop or rise of body temperature, or a drop or rise of temperature below or above a certain point, may be a sign of distress, which can be acted on by the medical staff. The medical staff may be alerted to this distress by the sensor  113 . 
         [0046]    An RFID enabled sensor  113 , may have a power source  120  that may be a battery, a receiver  140  for receiving polling and probing signals from an external detection device, a transmitter  150  to respond to such polling or probing requests, and a memory chip  152 . An RFID enabled sensor  113  may also be powered by the probing or polling signal from the external detection device. The receiver  140  may contain an integrated antenna  114  ( FIG. 7 ) for radio signals, or the antenna  114  may be stand alone. A poling or probing request, or an active signal from the sensor  113 , would update the external detection device  170  with all identification information stored on a memory chip  152 . An RFID sensor  113  would preferably be small notwithstanding the size of the battery, receiver, antenna  114  or other components of the present invention. The receiver  140  on the sensor  113  or an equivalent receiver on the external detection device  170  may be paired up with a transmitter  150  or an equivalent transmitter on the external detection device, forming a transponder. U.S. Pat. No. 4,384,288 is referenced in the present application for a more comprehensive overview of an RFID technology. An RFID enabled sensor  113  may be located even when the clamp  10  and the internal wire  110  has been severed or damaged, since the power necessary to drive the transmitter  150  would be supplied by the signal from the external detection device  170 . 
         [0047]    In an embodiment where the sensor  113  is a USID, the external detection device  170  would have a plurality of microphones that would detect and locate the high frequency polling sounds emitted by the sensor  113 . The sensor  113  would then utilize a specialized speaker element (not shown) coupled to a power source  120  to generate ultrasonic ping messages at predetermined intervals. In this embodiment an alarm is triggered when an expected polling sound from the sensor  113  is not detected by the external detection device  170 . This would indicate the device has been cut or damaged, or that the infant has been removed from the monitored area. A microwave enabled sensor would operate in a similar fashion with the difference being the frequency of wavelength being transmitted or received by the present invention. 
         [0048]    An embodiment of a sensor  113  that would connect to a wireless computer network may send out status and informational signals much the same way as in an ultrasound embodiment described above. However, in the Wi-Fi embodiment, the external detection device  170  may likely be a wireless antenna  114  that may be connected to an access point on a computer network that links monitoring equipment to the plurality of clamps  10  that are attached to the infants at the monitored facility. Cutting, damaging or carrying away of clamp  10  would trigger an alarm since the system would fail to receive a timely “I am alive” message at the next expected interval. Additionally, such a wireless antenna  114  may be calibrated to detect an especially strong signal, such as when an infant is being carried through a set of exit or entry gates (not shown) equipped with such an antenna  114 . The strong signal from the claimed invention would be especially strong, when in close proximity with such a gate and would therefore trigger an alarm. 
         [0049]      FIG. 6  shows another alternative embodiment of the present invention. Shown is an enlarged section  14 , sidewall  15 , a cover  16 , a dish  17 , a first end  30 , a second end  40 , a first jaw  51 , a second jaw  52 , a channel  53 , a hinge  60 , a dimple opening  62 , an additional locking mechanism  72 , a hook  75 , a catch  76 , sensor  113 , and a sleeve  130 . In this embodiment a conventional umbilical cord clamp may be slipped into the channels  53  of the sleeve  130 . The cover  16 , the dish  17  and the sensor  113  have been moved to the side of the sleeve, to enable easy insertion of a conventional clamp into the channel  53 . However, the cover  16  and the dish  17  may also be disposed at the second end  40  as in the prior figs. The same signaling technology may be employed in this embodiment as described above. 
         [0050]      FIG. 7  is a schematic representation of the circuitry within the present invention. Shown is a sensor  113 , represented by a dashed line and the components making up the sensor  113 . Also shown are the power source  120 ; a switch that is formed between the first terminal  111  and the second terminal  112 ; a wire  110  that is embedded in within the first and second jaws  51  and  52  and within the hinge  60 ; a receiver  140  and a transmitter  150 , both connecting to an antenna  114 . The antenna  114  is shown sending and receiving signals with an external detection device  170 . 
         [0051]    The present invention may be placed around an umbilical cord or an umbilical cord stump of an infant, and carry on all medically necessary functionality of a conventional clamp. Once the present invention is closed, it is permanently locked. The sensor  113  establishes communication with an external detection device  170 , such as an external antenna, access point or a plurality of these or other types of sensors. Additionally, a transmitter  150  within the sensor  113  of sufficient strength may be able to communicate with a satellite receiver. These types of sensors are well known in the art. There may also likely be some kind of interaction with a tracking technology, most likely a computer running a version of tracking software. The tracking technology may have a connection to the hospital&#39;s alarm or external speaker system or another type of warning or an alert implementation, which is triggered when a security incident is detected. 
         [0052]    It is preferable that the jaws  51  and  52  may be between 1 and 2 inches long. It is also preferable that the total length of the supervision device embodied by the present invention may be between 1 and 4 inches long. 
         [0053]    Although this invention has been described with a certain degree of particularity, it is to be understood that the present disclosure has been made only by way of illustration and that numerous changes in the details of construction and arrangement of parts may be resorted to without departing from the spirit and the scope of the invention.
