     BACKGROUND 
       [0002]    1) Field 
         [0003]    The field of the system described herein is security and safety systems for combining a plurality of wearable transceiver devices with cell phones or land-line based phones to establish contact with central monitoring systems. 
         [0004]    2) Description of the Related Art 
         [0005]    According to the National Highway and Traffic Safety Administration, the first 60 minutes of care after a multiple trauma injury are crucial. Trauma experts often refer to this crucial life or death time period as the “Golden Hour.” Experts in the field have determined that during the Golden Hour the likelihood of death increases 1 percent for every minute lost before emergency care arrives. 
         [0006]    Falls are one of the most serious health risks among seniors over the age of 65, affecting more people than stroke and heart attacks combined. More than half of all falls by seniors take place in the home. 50% of people who fall require assistance from someone else to get up. Getting help quickly after a fall reduces risk of hospitalization by 26% and death by over 80%. After a fall or other emergency, 90% of people who get help within one hour will continue independent living, but after 12 hours without help only 10% of people will continue to live at home. (New England Journal of Medicine) 
         [0007]    Senior citizens age 70 and over have the greatest risk of fire death. The fire death risk among seniors is more than double the average population. 
         [0008]    Senior citizens are also subject to Alzheimer&#39;s disease. One feature of this condition is the patient may wander from home and get lost. Another feature is that the patient may not be able to give his or her name and address to strangers so that they may be of assistance. 
         [0009]    Older adults want to use technology to age safely in their homes, but 80 percent of people 65-plus are not willing to pay more than $50 a month for the technology, a new AARP study says. The report found that people 65-plus want to try technology like home security services, sensors to detect falls, and devices to regulate temperature, lights and appliances, but are worried about installation and maintenance costs and technical issues. 
         [0010]    “Almost nine in ten older Americans want to be able to stay in their own homes and they are willing to use technology that can help them do that,” says Eleanor Ginzler, AARP Sr. Vice President for Livable Communities. 
         [0011]    U.S. Pat. No. 5,115,224, granted to Kostusiak et al May 19, 1992, describes a personal security system wherein a portable transmitter sends an emergency signal to several transceivers. One of the transceivers produces an alarm signal and sends the alarm signal to a central station. 
         [0012]    U.S. Pat. No. 5,305,370, granted to Kearns et al Apr. 19, 1994, describes a personal security system having a portable transmitter operable by the user, which transmitter can be operated in an emergency. Activation of the transmitter causes a base unit to operate a telephone line and dial 9-1-1. The telephone line also opens a two-way speaker system to allow voice-to-voice contact between the user and the emergency response monitor. The transmitter contains an emergency activation button to initiate the call and a cancel switch to end the calling process. 
         [0013]    U.S. Pat. No. 5,742,233, granted to Huffman et al Apr. 21, 1998, describes a personal security and tracking system in which a remote alarm switch may be carried by a user. When the user activates the switch a portable signaling unit carried by the user sends a transmission which includes geographical location to a central dispatch station. 
         [0014]    U.S. Pat. No. 6,044,257, granted to Boling et al Mar. 28, 2000, describes a cellular phone containing a large button which, when pressed, establishes voice-to-voice contact with an emergency response center. The cellular phone also carries a GPS system so that the emergency response center becomes aware of the phone&#39;s location. 
         [0015]    U.S. Pat. No. 6,166,639, granted to Pierce et al Dec. 26, 2000, describes a personal emergency response system comprising a sensor to be worn by the user. When the sensor is activated, distress information is transmitted from the sensor to a central monitoring station via a receiver, an auto-dialer, and a telephone line and voice-to-voice communication between the user and the station is established. 
         [0016]    U.S. Pat. No. 6,169,484, granted to Schuchman et al Jan. 2, 2001, describes a personal location system wherein users carry RF transponders provided with digital electronic identification numbers and emergency switches. There is a service center which monitors the location of the users who should remain within prescribed local areas. 
         [0017]    US Published Application No. 2003/0027547 filed by Wade on Jul. 16, 2001 describes an emergency communication system in which the user carries a wireless transceiver which, when activated, signals a base unit which in turn connects the user to a central monitoring station. 
         [0018]    U.S. Pat. No. 7,231,200, granted to Jenkins Jun. 12, 2007, describes a personal emergency communication system wherein a user-carried portable communications unit has a single button which, when depressed by the user, wirelessly sends a call request signal to a base unit. The base unit places a telephone call to an emergency response center and puts an emergency operator in voice-to-voice communication with the user.

       SUMMARY 
       [0020]    The present system addresses the issue of providing rapid emergency response following a vehicle crash and the issue of aiding the elderly to live in their own homes while assuring rapid contact with assistance providers in the event such assistance is needed. 
         [0021]    The present system is concerned with security and safety systems. The wearable transceiver devices of these systems refers to devices which may be worn or carried by a plurality of users in the same family or other group in or near their own dwelling areas or while traveling. The wearable transceiver device may take the form of key fobs, pendants, belt clips, and watches. When the user is at a long distance from his or her dwelling area it is necessary that the user also carry a cell phone allowing the person to be directly connected with a central monitoring station, an emergency response dispatcher, or a caregiver. Technically, a cell phone is a wearable transceiver device. However, in the present description and claims cell phones are expressly excluded from the grouping described by this term. The cell phone contains an assisted GPS chip to allow the determination of the geographical coordinates of the cell phone. The cell phone has the ability to establish voice-to-voice contact between the wearable transceivers and the central monitoring station. 
         [0022]    The wearable transceiver devices may be equipped with two 3-axis G-Force sensors, one programmed to be capable of detecting the event of a crash and the other being programmed to be capable of detecting the event of a perceived fall so that the device is capable of sensing a crash or fall. In the event of a crash or fall, the sensor activates a transmitter carried by the wearable transceiver device. Unless the transmitter is deactivated by the pressing of a communication button carried by the wearable transceiver device within a predetermined time, the device will remotely connect with either a cell phone or a land-line based phone to automatically dial a number connecting the wearable transceiver device with a central monitoring station. The cell phone also sends the geographical coordinates of the device via SMS. 
         [0023]    The wearable transceiver devices may connect with the central monitoring station through either a cell phone or land-line based phone if the user presses the communication button. In connecting to the central monitoring station, the cell phone sends the geographical coordinates as well as the ability to begin voice-to-voice communication. A plurality of persons in the same family or other group may be protected by the same system simultaneously. 
         [0024]    In order to insure the existence of battery power the wearable transceiver devices and the cell phone are equipped with reserve batteries which can provide emergency power to the main batteries in the event the main batteries lose their charge.

     DETAILED DESCRIPTION 
       [0031]    With reference to  FIGS. 1-5 , at least one embodiment of a safety and security system  2  is shown which is capable of connecting users  4  to central monitoring stations  6 . The system  2  is made up of wearable transceiver devices  8  which may take the form of key fobs, pendants, belt clips, and watches; a home-based stationary land-line based phone  10 ; a portable cell phone  12 ; cell phone towers  14  having geographical coordinate determining equipment; GPS-determining satellites  16 ; and a central monitoring station  6  having human monitors  18 . 
         [0032]    The wearable transceiver device  8  has a water-tight casing which permits the user  4  to carry it or wear it around the wrist or neck while in the shower. The wearable transceiver device  8  contains a small radio signal transceiver which may be worn or carried on the person. The wearable transceiver device  8  contains a speaker allowing the device  8  to be a speaker phone. The wearable transceiver device  8  has one accelerometer to determine the event of a fall and a second accelerometer to determine the event of a crash. The wearable transceiver device  8  has an audible timer which alerts the user  4  that a crash or fall event message will be sent to the central monitoring station  6  unless the transmitter is inactivated within a given time. The wearable transceiver device  8  has a communication button  20  which may be used to prevent the wearable transceiver device  8  from sending an unnecessary message indicating a fall or crash. The communication button  20  can also be pushed to put the user  4  in voice-to-voice communication with the central monitoring station  6 . The wearable transceiver device  8  communicates with the cell phone  12  or the home-based unit  10  via the well-known Zigbee radio signal transmission. 
         [0033]    In at least one embodiment, one of the features of the wearable transceiver devices  8  is built-in crash or perceived fall detection feature which is a 3-axis G-force sensor accelerometer programmed to report a fall upon a 1-5 G activation and a 3-axis G-force sensor accelerometer programmed to report a crash upon a 5 or more G activation. An example of such a feature is the BMA 150 device provided by Bosch. Another example is the triaxial accelerometer combined with two-way transceiver made available by Zigbee. When sensing a crash or perceived fall, data are calculated in the delta velocity (Delta V), which is the most accurate measurement. The knowledge of this data allows a monitor  18  to determine the severity of a crash and to inform the rescue personnel of what might be expected. Note that the sensor may be activated to send a preprogrammed signal to the land-line based phone  10  or the cell phone  12  by the user  4  falling or by the user  4  simply dropping the wearable transceiver device  8 . The sensor appreciates a sudden change in velocity but does not appreciate the distinction between these two events and in this specification the term “perceived fall” is used to describe both events. An accelerometer may be programmed to be activated by a 1 G force change which would indicate a fall and another accelerometer may be programmed to be activated by a 5 G force change which would indicate a crash. 
         [0034]    In at least one embodiment, the cell phone  12  contains an assisted GPS chip (AGPS). The AGPS operates as follows. From a cold boot-up, a regular (non-assisted) GPS receiver requires a strong signal in order to search and discover satellite  16  signals, decode information relating to satellite  16  positioning, and then calculate its position. This process can sometimes take up to several minutes depending on initial signal strength. This startup time is why GPS users don&#39;t like to turn off their GPS receivers. However, an always-on connection is a major problem for battery life in a cell phone  12 . AGPS discovers its position with the help of GPS equipment at cell phone towers  14 , which maintain a constant strong connection to GPS satellites  16 . The cell phone towers  14  use approximate positioning of the cell phone  12  and send pre-decoded ephemeris satellite positioning and clock information to the cell phone  12 . The result is that the cell phone will provide its position quickly, and thus be more conducive to having its GPS turned off and on to save the battery. 
         [0035]    As noted above, the wearable transceiver devices  8  may have accelerometer sensors which detect a perceived fall or a crash. Upon being activated by a perceived fall or crash the appropriate sensor activates a count-down timer in the transmitter. The timer contains a warning means which audibly counts down from a preset number of seconds (preferably 15) to zero. Prior to the time the timer reaches zero, the user  4  may deactivate the transmitter by pressing the below-described communication button  20 . The warning means serves to alert the user  4  that a call will be made unless the timer is deactivated. If the timer is not deactivated within the given period of time, the transmitter will send a signal to the home-based landline-based phone  10  or cell phone  12  by the Zigbee system. The transmitter communicates preferably with a landline-based phone  10 . In the event such a landline-based phone  10  cannot be detected, the notification system will search for a cell phone  12 . If data cannot be sent by one route, the device  8  will automatically select the next best route. Redundant routes which communicate with each other insure high reliability. From any given device  8  there are many different routes the data can take. The dynamic process of polling the network to find the quickest, most reliable, data path is a continual process. If any remote sensor devices in the network are unable to store and forward the data, then the network immediately analyzes and selects an alternate route insuring that the communications gets through to the cell phone  12  or landline-based phone  10 . The signal received by the cell phone  12  or landline-based phone  10  activates the phone  10   12  to dial the preprogrammed number of the central monitoring station  6 . The landline-based phone  10  makes a direct wire connection with the central monitoring station  6 . The cell phone  12  uses the Zigbee system to constantly self-adjust communication routes to connect with and optimize the flow of information to the central monitoring station  6 . This “smart routing” means the network is continually optimizing the pattern of communications to ensure the quickest, most reliable, path to the monitor  18 . Upon being connected with the central monitoring station  6  the cell phone  12  will transmit the AGPS-determined location cell phone  12  to the central monitoring station  6  via SMS and voice-to-voice connection will be established between the user  4  and the human monitor  18 . 
         [0036]    A communication button  20  is a prominent feature of the wearable transceiver device  8 . This button  20  may be the only button on the wearable transceiver device  8  or it may be one of up to three buttons. When there are other buttons on the device, this button  20  is larger than the others and, when appropriate, centrally located. This makes it easier for a visually handicapped user  4  or a user  4  in a panic mode to find the button  20 . To minimize the possibility of false alarms, it is preferred that this button  20  be located at a lower level than the plane of the surface of the wearable transceiver device  8  and to maximize the ease with which the button  20  may be found, it is preferred that there be a raised ring around the button  20 . This button  20  may be pushed while the timer is announcing the time remaining before the transmitter will contact the central monitoring station  6  in order to inactivate the transmitter. This button  20  may also be pushed by the user  4  under normal conditions to transmit a preprogrammed signal to the cell phone  12  or landline-based phone  10  to access the number of a central monitoring station  6  through a home-based landline phone  10  or a cell phone  12  to send the geographical coordinates of the cell phone  12  to the human monitor  18  via SMS and put the user  4  in voice-to-voice contact with the human monitor  18  using the transmitter and receiver of the wearable transceiver device  8 . 
         [0037]    The specification and claims will use the expression “human monitor”  18  to cover someone who is employed by, or otherwise associated with, the provider of the wearable transceiver devices  8  as well as private caregivers or public safety departments. It should be understood that the landline-based phone  10  and the cell phone  12  may be preprogrammed to contact any desired number. The human monitor  18  at the central monitoring station  6  is available at all times and may assist the user  4  in a variety of ways. The human monitor  18  at the central monitoring station  6  is trained in understanding the needs of at-risk individuals and emergency response protocol so that the human monitor  18  is able to handle each situation appropriately and efficiently. The human monitor  18  may dispatch proper help to the user&#39;s  4  location. Since the system  2  uses voice-to-voice technology, the human monitor  18  can determine the needs of the user  4 . Even if the user  4  cannot speak, the monitor  18  has instant access to key details of the user&#39;s  4  health history, a listing of key contacts, a listing of current medications, and a listing of allergies. The human monitor  18  is thus capable of calling the most appropriate source of assistance. This may be the local emergency response team and a neighbor who has a key to the user&#39;s  4  dwelling place to allow the emergency response team to enter the dwelling place of the user  4  without having to break down a door. The human monitor  18  has a prioritized list of caregivers who should be contacted in the event of an incident requiring caregiver assistance. The human monitor  18  stays connected to the user  4  until the proper source of assistance has arrived. 
         [0038]    A push of the communication button  20  connects the user  4  with a central monitoring station  6  when roadside assistance is needed and the human monitor  18  can direct appropriate assistance personnel to the vehicle. In the event of a widespread disaster, a push of the communication button  20  connects the user  4  with a human monitor  18  who can reestablish contact between the user  4  and other users  4  in the family, help guide the user  4  out of danger, and help to obtain water, food, etc. 
         [0039]    The human monitor  18  may supply the user  4  with local weather reports, local traffic reports, and current stock quotes. 
         [0040]    The human monitor  18  can keep track of the speed of a vehicle and the location of a vehicle. The user  4  may be notified when predetermined limits are exceeded. These services may be of value to owners of a stolen vehicle or parents of teenage drivers. 
         [0041]    The geo-fence  24  will be discussed with reference to  FIGS. 4 and 5 . The user  4  may establish a geo-fence  24  in a conventional manner. If a user  4  having a wearable transceiver device  8  moves outside the range of the cell phone  12  or the landline-based phone  10  an alarm event will be triggered. If the user  4  having a wearable transceiver device  8  but not having a cell phone  12  starts to go from inside to outside the alarm boundary  26  which is set a predetermined distance, e.g., 75 yards inside of the perimeter of the geo-fence  24 , the device  8  starts to beep for 15 seconds, warning the user  4  that the user  4  will not be protected outside of the geo-fence  24 . If the user  4  having a wearable transceiver device  8  but no cell phone  12  moves outside the geo-fence  24  the human monitor  18  would automatically be notified. In this way a user  4  with dementia can be alerted that he or she should not continue to stray from a pre-defined area. Also, the GPS function of the cell phone  12  can be used to locate the user  4  in the event the user  4  carrying a cell phone  12  happens to get lost. 
         [0042]    In at least one embodiment, a plurality of users  4  may carry and operate a plurality of wearable transceiver devices  8  associated with the same home-based land-line phone  10  or cell phone  12 . The cell phone  12  and the land-line based phone  10  can work either independently or in conjunction with each other; however if an emergency event is triggered either phone  10   12  can independently call the central monitoring station  6 . Thus, if there are two users  4  living together and they both require a wearable transceiver device  8  they would both be protected by the same home-based landline phone  10  or cell phone  12 . 
         [0043]    The wearable transceiver devices  8  contain small transceivers which send and receive radio signals via the Zigbee system. These devices  8  communicate directly with the home-based landline phone  10  or cell phone  12 . The home-based phone  10  and cell phone  12  have RF receivers and transmitters which allow them to use the Zigbee radio system to communicate with the wearable transceiver device  8  and with cell phone towers  14  using radio signals. The cell phone towers  14  can communicate with the satellite  16  of the GPS system using radio signals and with the cell phones  12  or home-based phones  10  using the Zigbee system radio system. Each of the cell phone  12  and the landline-based phone  10  contains a memory which allows it to store phone numbers the user  4  might wish to contact, including that of the central monitoring station  6 . 
         [0044]    A single user  4  or several users  4  may utilize the same system  2  at any given time. Each user  4  can be identified because the wearable transceiver device  8  has an RFID signature that allows the central monitoring station  6  to know which wearable transceiver device  8 , and therefore which user  4 , is making a call. For instance, if several users  4  are in a retirement home they can all be protected on the landline-based phone  10  and if for some reason two users  4  send alarms to the central monitoring station  6  at the same time, the central monitoring station  6  would search for the cellular system  2  protecting more than one person  4  at the same time. The RFID identifies a particular user  4  and the central monitoring station  6  has medical information such as allergies, medical history, present medical condition, and present medications on file. Thus, in notifying an emergency response team, useful information concerning the patient  4  may be known by the team before they reach the patient  4 , saving valuable time. 
       Example 1 
       [0045]    Person One  4  leaves the house with his wearable transceiver device  8  and cell phone  12  and goes outside the geo-fence  24  but still within range of the wearable transceiver device  8  of Person Two  4 . Because of the cell phone  12 , he is protected as long as the cell phone  12  can contact the central monitoring station  6 . Person Two  4 , who is at home, slips and falls while wearing a wearable transceiver device  8  and person One  4  is unaware of this. However, the fall sensor in the wearable transceiver device  8  detects a fall and contacts the central monitoring station  6  via the landline-based phone  10 . 
         [0046]    Even if the landline-based phone  10  became unavailable because of cut or downed wires the cell phone  12  would still be available to contact the central monitoring station  6 .
