     DETAILED DESCRIPTION 
     Reference is made to  FIGS. 1A and 1B , which are simplified pictorial illustrations of a system for monitoring residents of a health care facility, constructed and operative in accordance with a preferred embodiment of the present invention. The system of  FIGS. 1A and 1B  preferably comprises a plurality of tamper-resistant resident monitoring devices, each of the devices being uniquely associated with a resident of the facility, a multiplicity of device detectors operative to communicate with the monitoring devices and a computer subsystem operative to communicate with the plurality of tamper-resistant resident monitoring devices via the multiplicity of device detectors, and to thereby monitor the residents of the facility. It is appreciated that the monitoring devices of  FIGS. 1A &amp; 1B  are typically employed to monitor the whereabouts of residents of a health care facility, and may also be employed to monitor and report health-related parameters of the resident such as, for example, heart rate and blood oxygen levels. 
     As shown in  FIG. 1A , the system resides on a server  100  located at a nursing home  102 . Server  100  is preferably connected to an enterprise-wide network  104  that connects between similar servers  106  located at other health care facilities which maybe managed jointly with nursing home  102 . A multiplicity of resident location detectors  110  are deployed throughout nursing home  102 , which detectors  110  communicate with a plurality of tamper-resistant resident monitoring devices  112  and with server  100 . Devices  112  are typically worn by each of the residents of nursing home  102 , and preferably include a wristband  114  and a monitoring portion  116 . 
     Door controllers  120  are provided for controlling magnetic door locking mechanisms  122  which are associated with doors  124  of nursing home  102 . Locking mechanisms  122  are preferably operative to lock or unlock doors  124  responsive to signals received from server  100  via door controllers  120 . 
     As seen in  FIG. 1A , a resident of nursing home  102  wearing a monitoring device  112  approaches a door  124  which he is not authorized to open. A location detector  110  communicating with device  112  ascertains that the resident is in the vicinity of door  124  and communicates the location of the resident to server  100 . Server  100  ascertains that the resident is not authorized to exit door  124 , and therefore sends a signal to door controller  120  associated with door  124  instructing controller  120  to lock door  124 . 
     As further shown in  FIG. 1A , responsive to receiving the signal from server  100 , controller  120  employs locking mechanism  122  to lock door  124 , thereby preventing the resident from exiting door  124 . 
     It is a particular feature of the present invention that wristband  114  is formed of an electrically conductive material such as, for example, KennElec 9719, commercially available from Kenner Material &amp; System Co., Ltd. of Jhongli City, Taiwan. Wristband  114  is preferably galvanically connected to monitoring portion  116 . Therefore, any breach of wristband  114  or disconnecting of wristband  114  from monitoring portion  116  causes the opening of an electrical circuit and is thereby operative to cause device  112  to signal that it has been tampered with. 
     Turning now to  FIG. 1B , it is shown that a resident of nursing home  102  tampers with a device  112  which is fastened to his wrist, and succeeds in removing device  112  from his wrist by disconnecting wristband  114  of device  112  from monitoring portion  116 . As seen in  FIG. 1B , a detector  110  communicating with device  112  detects that device  112  has been tampered with, and sends a notification to server  100  notifying the system of the tampering. Responsive to the notification, server  100  preferably sends a multiplicity of alarm notifications to the staff of nursing home  102 . 
     As shown in  FIG. 1B , the alarm notifications include, for example, a message which is sent to a computer  130  of a staff member of nursing home  102 , an alert which appears on a console  132  which is readily visible to staff members of nursing home  102 , and a text message which is sent to a mobile device  134  of a staff member of nursing home  102 . It is appreciated that the alerts may be, for example, any suitable combination of audio and visual alerts, and preferably include information pertaining to the identity of the resident and his last known location. 
     Additionally, server  100  preferably sends signals to door controllers  120  associated with all the doors  124  of nursing home  102  instructing controllers  120  to lock doors  124  and to thereby prevent unauthorized exit of the resident from nursing home  102 . 
     Reference is now made to  FIG. 2 , which is a simplified pictorial illustration of a system for monitoring whereabouts of residents of a health care facility, constructed and operative in accordance with another preferred embodiment of the present invention. The system of  FIG. 2  preferably includes a plurality of tamper-resistant resident monitoring devices, each of the devices being uniquely associated with a resident of the facility and a computer system operative to communicate with the multiplicity of monitoring devices, and to thereby monitor the whereabouts of the residents. 
     As shown in  FIG. 2 , an emergency situation, such as a fire at a nursing home  200  forces residents  202  of nursing home  200  to evacuate nursing home  200  to an evacuation area outside of nursing home  200 . Tamper-resistant resident monitoring devices  210  associated with each of residents  202  are preferably fastened to a wrist of each of residents  202  and preferably communicate resident whereabouts with a portable monitoring system  220 . Communication between devices  210  and system  220  is typically of a wireless nature. 
     It is a particular feature of this embodiment of the present invention that each of devices  210  located within a predefined range from system  220  is operative to communicate with system  220  and to notify system  220  of the presence of the resident  202  associated therewith within the predefined range. Devices located outside of the predefined range from system  220  will fail to communicate with system  220 , and residents associated therewith are therefore marked by system  220  as being unaccounted for. In the example of  FIG. 2 , two residents of nursing home  200  are reported by system  220  as being unaccounted for. 
     Reference is now made to  FIGS. 3A and 3B , which are simplified pictorial illustrations of a system for monitoring whereabouts of residents of a health care facility, constructed and operative in accordance with a further preferred embodiment of the present invention. The system of  FIGS. 3A and 3B  preferably comprises a plurality of tamper-resistant resident monitoring devices, each of the devices being uniquely associated with a resident of the facility, a multiplicity of resident location detectors operative to communicate with the monitoring devices, and a computer system operative to communicate with the multiplicity of resident location detectors, and to thereby monitor the residents of the facility. 
     As shown in  FIG. 3A , the system resides on a server  300  located at a nursing home  302 .

A multiplicity of resident location detectors  310  are deployed throughout nursing home  302 , which detectors  310  communicate with a plurality of tamper-resistant resident monitoring devices  312  and with server  300 . Devices  312  are typically worn by each of the residents of nursing home  302 . 
     Server  300  also preferably communicates with a central elevator control system of nursing home  302 , and is operative to thereby control elevator doors  322  of elevators  324 , in particular to prevent the closing of elevator doors  322  when a resident who requires accompaniment when riding an elevator  324  enters an elevator  324  without suitable accompaniment. 
     As shown in  FIG. 3A , a resident of a nursing home  302  wearing a monitoring device  312  enters an elevator  324 . A location detector  310  located inside elevator  324  and communicating with device  312  ascertains that the resident has entered elevator  324  and communicates the presence of the resident in elevator  324  to server  300 . Server  300  ascertains that the resident is currently the sole occupant of elevator  324  and that he is not authorized to ride elevator  324  without suitable accompaniment. Server  300  therefore sends a signal to the central elevator control system of nursing home  302  instructing the central elevator control system to prevent closure of elevator doors  322 . 
     Turning now to  FIG. 3B , it is shown that a resident of nursing home  302  wearing a monitoring device  312  enters elevator  324  together with a member of the nursing home staff who is wearing an electronic tag  326 . A location detector  310  located in elevator  324  and communicating with device  312  ascertains that the resident has entered elevator  324  and communicates the presence of the resident in elevator  324  to server  300 . Location detector  310  also ascertains that the staff member has entered elevator  324  and communicates the presence of the staff member to server  300 . 
     Server  300  ascertains that the resident is currently accompanied by the staff member and is therefore authorized to ride elevator  324 . Server  300  therefore sends a signal to the central elevator control system of nursing home  302  instructing the central elevator control system to allow closure of elevator doors  322 . 
     Reference is now made to  FIG. 4A , which is a simplified pictorial illustration of a tamper-resistant monitoring device which is part of the system of  FIGS. 1A-3B .

     Upon insertion into recesses  498 , resilient retaining flaps  494  of brackets  492  are preferably lodged into an upper portion of recesses  498  which portion is not aligned with recesses  496 , thereby preventing removal of brackets  492  from recesses  496  and  498 , and thereby tamper-resistantly locking wristband elements  404  and  406  to monitoring portion  402 . It is appreciated that brackets  492  provide a galvanic link between wristband elements  404  and  406  and monitoring portion  402 . 
     It is a particular feature of the present invention that brackets  492  are lodged into recess  498  and are thereby tightly retained in wristband elements  404  and  406 . This feature is operative to guarantee that upon attempting to disconnect either of wristband elements  404  and  406  from monitoring portion  402 , at least one of flaps  494  will be torn from corresponding bracket  492 , thereby disconnecting the galvanic link between wristband elements  404  and  406  and monitoring portion  402 , and thereby opening an electrical circuit embodied therewithin. The opening of the electrical circuit is operative to create an electronic signal notifying of the disconnecting of either of wristband elements  404  and  406 . This electronic signal is then preferably transmitted by main circuit board  466  to an external monitoring receiver, such as location detectors  110  of  FIGS. 1A &amp; 1B . 
     Reference is now made to  FIGS. 5A and 5B , which are simplified pictorial illustrations of the operation of the system of  FIGS. 1A-4C  in registering a new resident at a health care facility. The system preferably resides on a server  500  located at a nursing home  502 . Server  500  is preferably connected to an enterprise-wide network  504  which preferably connects between servers  506  located at other related health care facilities. It is appreciated that the registration of a resident at the health care facility includes, inter alia, registering a monitoring device to the resident. It is imperative that each monitoring device be uniquely assigned to one particular resident. 
     As shown in  FIG. 5A , John, a new resident at nursing home  502 , is introduced to an administrator of nursing home  502 . The administrator initially records John&#39;s personal details, such as John&#39;s full name, date of birth, and an identification number on the system. The identification number may be any unique identification number, such as a U.S. Social Security number. 
     As further shown in  FIG. 5A , the administrator then selects a monitoring device  510  and attempts to register device  510  in the system by first pressing a registration button  512  on device  510 . A first registration signal is then emitted by device  510  and received by at least one of location detectors S 20  which are mounted throughout nursing home  502  and which are connected to the system residing on server  500 . 
     Turning now to  FIG. 5B , it is shown that upon receiving the first registration signal, the system notifies the administrator that registration of a particular monitoring device having a particular serial number, such as #6, has been attempted. The administrator then reviews a device registration table  530  provided by the system to verify that device #6 is not registered to any other resident of nursing home  502  or any other related health care facilities. Upon verifying that device #6 is available, the administrator assigns device #6 to John by entering John&#39;s personal details into table  530 . 
     To complete the registration process of device  510  to John, the administrator once again presses registration button  512  on device  510 . A second registration signal is then emitted by device  510  and received by at least one of location detectors  520  which are mounted throughout nursing home  502  and which are connected to the system residing on server  500 . Upon receiving the second registration signal, the system notifies the administrator that registration of monitoring device #6 to John has been completed. 
     It is a particular feature of the present invention that the registration process described hereinabove, by which the assignment of a monitoring device to a resident is coupled with physical registration signals that are emitted by the device and received by the system, is operative to guarantee that each monitoring device be uniquely assigned to one particular resident. 
     It is appreciated that upon discharge of a resident from nursing home  502 , the resident&#39;s details are deleted from table  530 , thereby making the device registered to the discharged resident available for reassignment to a new resident. 
     Reference is now made to  FIG. 6 , which is a simplified flowchart indicating steps in the execution of a method for uniquely registering a resident of a health care facility which employs the system of  FIGS. 1A-4C . The method of  FIG. 6  preferably includes designating a tamper-resistant resident monitoring device to be associated with the resident, employing the device to send a first registration signal to a resident registration system, responsive to receiving the first registration signal, ascertaining that the device is not associated with a resident other than the resident, employing the resident registration system to associate the device with the resident and employing the device to send a second registration signal to the resident registration system. 
     As shown in  FIG. 6 , upon initializing the registration process of a new resident in step  600 , the personal details of the new resident are typically entered into the system in step  602 . A monitoring device is then selected in step  604  to be registered to the new resident. To initiate the registration of the device to the new resident, a registration button on the selected device is pressed in step  606 , resulting in a first registration signal being emitted from the device and received by the system in step  608 . 
     Thereafter, in step  610 , it is verified that the device is not registered to any other resident. If the device is not registered to any other resident, the device is assigned to the new resident in step  612 . Thereafter, in step  614 , the device registration button is pressed once again, resulting in a second registration signal being emitted from the device and received by the system in step  616 , thereby completing the registration of the device to the new resident in step  618 . 
     It will be appreciated by persons skilled in the art that the present invention is not limited by what has been particularly shown and described hereinabove. Rather the scope of the present invention includes both combinations and subcombinations of the various features described hereinabove as well as modifications thereof which would occur to persons skilled in the art upon reading the foregoing description and which are not in the prior art. 
     While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
