     DESCRIPTION OF THE PRESENTLY PREFERRED EXEMPLARY EMBODIMENTS 
     While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detailed preferred embodiment of the invention with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the broad aspect of the invention to the embodiment illustrated. 
     The numerous innovative teachings of the present application will be described with particular reference to the presently preferred embodiment, wherein these innovative teachings are advantageously applied to the particular problems of a personal safety device system and method. However, it should be understood that this embodiment is only one example of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed inventions. Moreover, some statements may apply to some inventive features but not to others. 
     The present invention includes a personal safety device ( 101 ) or apparatus which may be worn by the user for example around the neck or ankle of the user and which may be attached to a band ( 601 ) shown in  FIG. 6  or the personal safety device may be pinned to clothing of the user. In alternate embodiments, the user may be non-human. Thus, where the user is an animal, the personal safety device ( 101 ) may be affixed to the user&#39;s collar, harness, leash, or article of clothing. 
     The present invention may record and or transmit upper or lower exposure temperatures of the user who is using the personal safety device, and the present invention may record and transmit the ambient temperature associated with the user of the personal safety device, the skin temperature of the user who is using the personal safety device and/or the combination of the ambient temperature and the skin temperature of the user. If the temperature recorded by the personal safety device reaches or exceeds an upper or lower exposure predetermined threshold temperature limit for a predetermined length of time, the personal safety device may activate an audible alarm of the personal safety device, send a message such as a text message to a nearby receiver by blue tooth or other network capabilities and send an alert (audio or text) by cellular service to one or more telephone numbers or any combination of the three. 
     The personal safety device of the present invention may include a device to include a global positioning system GPS to provide a physical location of the user of the personal safety device at any time, and the movement of the personal safety device may be disabled during rigorous activity in order to prevent the transmission of a false signal. 
     The personal safety device of the present invention can be reprogrammed by a reprogramming device by the user of the personal safety device, can be reprogrammed remotely by a Bluetooth connection more from a computer or smart phone and can be reprogrammed by a network administrator. The predetermined threshold temperature may be adjusted by the reprogramming device. 
     The personal safety device may be locked onto the user to prevent the personal safety device from being removed from the user so that it can be only removed by a key. 
     The personal safety device of the present invention may be inserted into a body piercing (like an earring) in order to achieve better temperature measurements and may be inserted completely under the skin of the user so that the personal safety device can only read body temperature. 
     The personal safety device of the present invention may be incorporated into a watch such as a wrist watch or other type of band. 
     The personal safety device of the present invention may include an electronic display in order to display information such as the current skin temperature. 
     The personal safety device of the present invention may be formed with a sports helmet such as a football helmet or other types of clothing in order to monitor the temperature of the helmet or clothing in an effort to prevent hypothermia. 
       FIG. 1  illustrates a circuit diagram of the personal safety device ( 101 ) which may include a controller ( 103 ) to control the personal safety device ( 101 ). The controller ( 103 ) may be connected to a multitude of temperature sensors which may include a first temperature sensor ( 105 ) and may be connected to a second temperature sensor ( 107 ) which may be placed on different locations on the user of the personal safety device ( 101 ) in order to provide a diversity of temperatures. 
     The controller ( 103 ) may be additionally connected to an audible alarm device ( 109 ) which may be activated by the controller ( 103 ) if the first temperature sensor ( 105 ) or the second temperature sensor ( 107 ) exceeds a range either plus or minus from a predetermined threshold temperature. Furthermore, the controller ( 103 ) may be additionally connected to a wireless communication device ( 111 ) (transmitter) which may form a Bluetooth connection or wireless connection from the controller ( 103 ) to a wireless receiver and transmitter (a remote device) ( 113 ) to receive temperature information including alarm information from the first temperature sensor ( 105 ) and or the second temperature sensor ( 107 ) and location information obtained from the location sensor ( 115 ) which may be a GPS device. The wireless receiver and transmitter ( 113 ) may transmit information to the controller ( 103 ) in order to change values such as the predetermined threshold temperature. In addition, the controller ( 103 ) may receive motion information from the motion sensor ( 117 ) in order to deactivate the alarm information from being sent to the remote device ( 113 ) when the motion sensor ( 117 ) detects motion which exceeds a predetermined motion value which may correspond to vigorous exercise which may naturally raise the temperature of the user. 
     The controller ( 103 ) may be connected to a reprogramming device ( 121 ) to allow the user to reprogram the controller ( 103 ) by changing the predetermined motion value or the predetermined threshold temperature. The reprogramming device ( 121 ) may include a display ( 123 ) to display information from the controller ( 103 ) and may include a keyboard ( 125 ) to input information into the controller ( 103 ). 
     Furthermore, the remote device ( 113 ) may include a transmitter to transmit reprogramming information including the predetermined motion value or the predetermined threshold temperature to the wireless communication device ( 111 ) which will reprogram the controller ( 103 ). 
     The location sensor ( 115 ) may be a GPS device and may provide location information of the user to the controller ( 103 ). 
     The motion sensor ( 115 ) may provide motion information of the user to the controller ( 103 ). When the motion information exceeds a motion threshold value, the controller ( 103 ) may conclude that the user has engaged in heavy activity so that an increase in temperature from the temperature sensors ( 105 ,  107 ) can be safely ignored and will not activate the audible alarm ( 109 ). 
     In operation, the first temperature sensor ( 105 ) and the second temperature sensor ( 107 ) sense temperature data from the user and transmit the temperature data to the controller ( 103 ), and the location sensor ( 115 ) determines the location of the user and transmits location information to the controller ( 103 ). Additionally, the motion sensor ( 117 ) senses the motion of the user and transmits motion information to the controller ( 103 ). If the temperature information exceeds the predetermined threshold temperature, and if the motion information is not exceeding a predetermined threshold motion value, the controller ( 103 ) activates the wireless communication device ( 111 ) to send an alarm to the remote device ( 113 ) to allow a second user to be notified of the temperature change of the user. In addition, the controller ( 103 ) activates the audible alarm ( 109 ) to provide an audible alarm signal. If the motion information exceeds the predetermined threshold motion value, then the controller ( 103 ) will not activate the communication device  111  or the remote device ( 113 ). 
       FIG. 2  illustrates another personal safety device ( 201 ) which may include a battery ( 202 ) to supply power to the temperature sensor and switch ( 203 ) and the wireless transmitter ( 205 ). The temperature sensor and switch ( 203 ) may send a first signal which may be a high level alarm to the wireless transmitter ( 205 ) when the temperature of the user exceeds a first predetermined threshold temperature and a second signal which may be a low level alarm to the wireless transmitter ( 205 ) when the temperature of the user drops below a second predetermined threshold temperature. 
     The wireless transmitter ( 205 ) receives the first signal and or the second signal from the temperature sensor and switch ( 203 ) and transmits the first signal or the second signal to a wireless receiver ( 207 ) which may be remote from the personal safety device ( 201 ). The wireless receiver ( 207 ) may transmit the received signal from the wireless transmitter ( 205 ) to a wireless device ( 209 ) which may receive the first signal or the second signal which may be communicated to a second user. 
       FIG. 3  illustrates another personal safety device ( 301 ) which may include a battery ( 202 ) to supply power to the temperature sensor and switch ( 203 ), the interface receiver ( 216 ) and the cell phone transmitter ( 211 ).

The cell phone carrier ( 213 ) may transmit the received signal from the cell phone transmitter ( 211 ) to a cell phone ( 215 ) which may receive the first signal or the second signal which may be communicated to a second user. 
     The second user may transmit a replacement first predetermined threshold temperature and a replacement second predetermined threshold temperature from the cell phone ( 215 ) to the cell phone carrier ( 213 ), and the cell phone carrier ( 213 ) may transmit the replacement first predetermined threshold temperature and the replacement second predetermined threshold temperature to the interface receiver ( 216 ) which may be positioned within the personal safety device ( 301 ). The interface receiver ( 216 ) may transmit the first predetermined threshold temperature and the second replacement predetermined threshold temperature to the temperature sensor and switch ( 203 ) to replace the first and second predetermined threshold temperature. 
       FIG. 4  illustrates another personal safety device ( 401 ) which may include a battery ( 202 ) to supply power to the temperature sensor and switch ( 203 ), the global positioning satellite device (GPS) ( 216 ) and the cell phone transmitter ( 211 ). The temperature sensor and switch ( 203 ) may send a first signal which may be a high level alarm which may include position data of the personal safety device ( 401 ) to the cell phone transmitter ( 211 ) when the temperature of the user exceeds a first predetermined threshold temperature and a second signal which may be a low level alarm which may include position data of the personal safety device ( 401 ) to the cell phone transmitter ( 211 ) when the temperature of the user drops below a second predetermined threshold temperature. 
     The cell phone transmitter ( 211 ) receives the first signal and or the second signal from the temperature sensor and switch ( 203 ) and transmits the first signal or the second signal to a cell phone carrier ( 213 ) which may be remote from the personal safety device ( 301 ). The cell phone carrier ( 213 ) may transmit the received signal from the cell phone transmitter ( 211 ) to a cell phone ( 215 ) which may receive the first signal or the second signal which may be communicated to a second user. The second user not only receives the high or low level alarm signal but receives the location data of the user of the personal safety device ( 401 ). 
       FIG. 5  illustrates another personal safety device ( 501 ) which may include a battery ( 202 ) to supply power to the switchboard ( 231 ), the temperature sensor bank ( 233 ) to measure the temperature of the body from a multitude of sensors and the cell phone transmitter ( 211 ). The switchboard ( 231 ) may send a first signal which may be a high level alarm to the cell phone transmitter ( 211 ) when the temperature of the user exceeds a first predetermined threshold temperature and a second signal which may be a low level alarm to the cell phone transmitter ( 211 ) when the temperature of the user drops below a second predetermined threshold temperature.

     Preferred Embodiment Personal Safety Device System in an Automobile Block Diagram ( 0700 ) 
     The present invention may be seen in more detail as generally illustrated in  FIG. 7  ( 0700 ), wherein a user wearing a personal safety device ( 0702 ) is positioned in an automobile ( 0703 ). The personal safety device ( 0702 ) may be paired with an automobile electronics system (AES) ( 0701 ). According to a preferred exemplary embodiment, the personal safety device detects unsafe temperature conditions and communicates a signal to the AES ( 0701 ) which reacts and alleviates the unsafe temperature conditions. The AES ( 0701 ) may start the engine and turn on air conditioning, turn on hazard lights, unlock the door or inform a third party provider. 
     Preferred Embodiment Personal Safety Device System Block Diagram ( 0800 ) 
     The present invention may be seen in more detail as generally illustrated in  FIG. 8  ( 0800 ), wherein a user ( 0833 ) wearing a personal safety device ( 0832 ) is positioned in an automobile ( 0830 ). The safety device ( 0832 ) may be paired with automobile electronics system (AES) ( 0831 ) via generally available wireless protocols such as Bluetooth. The safety device ( 0832 ) may also be connected with the AES ( 0831 ) using a wired connection and paired using networking protocols such as Ethernet. A more detailed illustration of the device in communication with AES ( 0831 ) is shown below in  FIG. 9  ( 0900 ). The safety device ( 0832 ) may also be connected to a remote third party provider that may monitor the safety device. The third party provider may send/receive commands/data to/from safety device ( 0832 ) through a network ( 0801 ). The network ( 0801 ) may include a wired protocol such as Ethernet or wireless protocol such as 3G, 4G, WIFI, NFC, WLAN, and LTE. The safety device ( 0832 ) may connect to the network ( 0801 ) through a network connection ( 0850 ). The network connection ( 0850 ) may include wireless protocol such as 3G, 4G, WIFI, NFC, WLAN, and LTE. 
     Third party providers/administrators may connect to the safety device ( 0832 ) through a network ( 0801 ) and configure parameters in the device such as threshold temperature, monitoring period, and/or monitoring frequency using a safety computing device (SCD) ( 0820 ). A controller in the safety device senses a user&#39;s body temperature. The controller also calculates a temperature delta (difference) between the sensed temperature and the threshold temperature. In one preferred exemplary embodiment, the safety device transmits the temperature delta information at the set monitoring frequency to SCD ( 0820 ) for a set monitoring period. The third party provider may monitor the temperature delta information and maintain a log. In another exemplary embodiment, the third party provider may detect unsafe temperature conditions in the received temperature delta and react accordingly. In one example, the threshold temperature may be set at 104° F. for human body temperature, the monitoring frequency may be set to 15 minute intervals, and the monitoring period may be set to 24 hours a day. In this scenario, if the human temperature is detected to be 105° F., the temperature delta is greater than zero which may be considered an unsafe condition for the user. The provider may then alert an emergency official ( 0811 ) such as police/EMR/Hospital or a remote user ( 0841 ) with a mobile computing device ( 0842 ). The remote user may be connected to safety device ( 0832 ) and to the network ( 0801 ). In one exemplary embodiment, the remote user may be a parent monitoring a child with the device traveling in an automobile. In another example, an elderly person with the device traveling in an automobile may be monitored by a remote user. 
     A controller in the safety device senses ambient temperature. The controller may also calculate a temperature delta (difference) between the sensed temperature and the threshold temperature. In one preferred exemplary embodiment, the safety device transmits the temperature delta information at the set monitoring frequency to SCD ( 0820 ) for a set monitoring period. The third party provider may monitor the temperature delta information and maintain a log. The log may be stored in a local safety database SDB ( 0824 ). In one example, the threshold temperature may be set at 100° F. for human body temperature, the monitoring frequency may be set to 15 minute intervals, and the monitoring period may be set to 24 hours a day. In this scenario, if the ambient temperature is detected to be 110° F. inside the automobile, the temperature delta may be calculated to be 10° F. which may be considered an unsafe condition for the user. 
     The SCD ( 0820 ) is configured for enabling third party providers to interact the safety device ( 0832 ) via network ( 0801 ). The SCD ( 0820 ) may further comprise a microprocessor executing instructions read from a computer-readable medium ( 0821 ) and a graphical user interface (GUI) ( 0822 ) with a pointing device. The providers may open GUI ( 0822 ) and select a safety database (SDB) ( 0824 ) for updating/retrieving records. The administrators may receive data through the SCD ( 0820 ) or manually. 
     According to a preferred exemplary embodiment, the third party provider via SCD ( 0820 ) may receive device status information periodically at a set interval to determine if the device is functioning. If the safety device does not send a signal indicating its status, the third party provider may consider it to be device malfunction and notify concerned officials and stakeholders. For example, if the device fails to send status information for three consecutive intervals, the third party provider may alert concerned officials to assist the user with malfunctioning device. 
     Preferred Embodiment Personal Safety System Block Diagram ( 0900 ) 
     The present invention may be seen in more detail as generally illustrated in  FIG. 9  ( 0900 ), wherein a personal safety device ( 0902 ) is in network communication with an automobile electronic system AES ( 0901 ). The personal safety device ( 0902 ) may comprise a device transmitter ( 0914 ), a device receiver ( 0913 ), a device controller ( 0930 ), a temperature sensing unit ( 0931 ), an alarm ( 0932 ), a motion sensor ( 0933 ), a GPS module ( 0934 ), and a network port ( 0935 ). The automobile electronic system (AES) ( 0901 ) may comprise an automobile transmitter ( 0912 ), an automobile receiver ( 0911 ), an automotive controller ( 0920 ), a door control unit ( 0923 ), a hazard control unit ( 0924 ), and an Air Conditioned control unit ( 0925 ). 
     A network connection (“data link”) may need to be established between personal safety device (PSD) ( 0902 ) and the AES ( 0901 ) before communicating with each other. The network connection may be a wired connection using a copper wire or a wireless connection using such protocols as Bluetooth. The wired connection may be established by a generally available protocol such as Ethernet. The device transmitter ( 0914 ) transmits data/signal to automotive receiver ( 0911 ) and conversely device receiver ( 0913 ) receives data from automotive transmitter ( 0912 ). A threshold temperature may be programmed into the PSD ( 0902 ) via a graphical interface or through the network port ( 0935 ). When the PSD ( 0902 ) is enabled to sense an ambient temperature or a user&#39;s temperature, the PSD calculates a temperature delta between the sensed temperature and the programmed threshold temperature. For example, when the calculated temperature delta is greater than  0 , the device transmitter ( 0914 ) may transmit data/signal to automotive receiver ( 0911 ) indicating unsafe conditions. According to an exemplary embodiment, the automotive controller reacts to the unsafe conditions and may direct an air conditioned unit ( 0925 ) to turn on or switch on hazard lights through hazard control unit ( 0924 ) or unlock automobile doors through the door control unit ( 0923 ). The automotive controller may also sound a horn to seek attention when unsafe conditions are detected. The PSD ( 0902 ) may also alert a remote user or a third party provider through network port ( 0935 ) when unsafe conditions are detected.

           After the personal safety device is coupled to a user, it may be programmed on an interface or remotely through network port.   
           (2) sensing a temperature with the temperature sensing unit ( 1002 );   (3) calculating the temperature delta between the sensed temperature and the threshold temperature ( 1003 );   (4) determining if the temperature delta identifies unsafe conditions ( 1004 );   (5) transmitting a signal to concerned authorities ( 1005 ); and
           the device may send a notification to authorities such as emergency personnel, law enforcement or to a person responsible for the device user.   
           (6) reacting to the unsafe conditions and taking necessary action to alleviate the unsafe conditions ( 1006 ).
