Abstract:
A security device paired with a user&#39;s cell phone is operable by either a trigger or an accelerometer. The device includes visual and audio alarms, a prerecorded message and an audio recording of the ambient noise. Depression of the trigger will spray mace onto an attacker, activate the alarms and alternately send the message and recording to 9-1-1 or other security monitor. Alternatively, the accelerometer will so activate the device. The alarms and transmissions are synchronized so as to not interfere one with the other. Direct communication with 9-1-1 via the Bluetooth®/cell phone interface is immediately established either by a push-to-talk button or at the termination of a predetermined alarm and message transmission period.

CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of provisional application Ser. No. 61/075,089, filed Jun. 24, 2008, entitled “Improved Physical Security Device.” 
    
    
     BACKGROUND OF THE INVENTION 
     This invention relates to a security device and, more particularly, to a device presenting countermeasures to defend against personal attacks, including alarms to frighten the attacker and/or alert others, as well as audio and visual communications advising others of the incident. 
     The desire for personal security is a burgeoning one resulting in personal security devices being available on the marketplace. Such devices range from weapons designed to inflict harm on an attacker to alarms designed to call attention to the situation at hand so as to dissuade an attacker from further aggression. 
     Although such devices are assumably effective in operation, it is desirable to have a device which presents a plurality of security functions which allows the user to defend against dangerous situations and communicate the impending situation in various audio and visual forms to others. 
     In response thereto we have invented a personal security device which presents a plurality of security features including weapon-type functions, visual and audio alarms and audio and visual recordings for transmission to 9-1-1 or other preselected numbers. Such functions may either be initiated by the user or automatically activated during physical confrontations. The device is in the form of a pistol configuration which enables the user to better manipulate the device and control the available functions. 
     It is therefore a general object of this invention to provide a security device presenting a plurality of security functions. 
     Another object of this invention is to provide a device, as aforesaid, which can inflict physical harm upon an attacker. 
     Still another object of this invention is to provide a device, as aforesaid, which activates audio and/or visual alarms so as to call attention to the altercation and/or frighten the attacker. 
     Another object of this invention is to provide a device, as aforesaid, which enables the user to accurately direct mace upon the attacker and mark the attacker with a tracer substance to assist in subsequent identification. 
     A still further object of this invention is to provide a device, as aforesaid, which links with a cell phone so as to automatically alert 9-1-1 and/or send prerecorded audio messages as well as audio and visual recordings of the altercation to 9-1-1 or other preselected numbers. 
     Another object of this invention is to provide a security device, as aforesaid, which repeatedly transmits the audio/or visual recordings. 
     A still further object of this invention is to provide a security device, as aforesaid, which provides a direct voice communication link with 9-1-1 or other preselected numbers. 
     A further object of this invention is to provide a device, as aforesaid, which can be user activated or automatically activated if the item is thrown at the attacker or jostled during an altercation. 
     Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawings, wherein is set forth by way of illustration and example, a now preferred embodiment of this invention.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Turning more particularly to the drawings,  FIGS. 2 and 16  show the device as utilizing a pistol-shaped housing  11  for containing the various to-be-described components therein. Such components include a power board  38  ( FIGS. 4-4A ) and an electronics PC board  41  as shown in  FIGS. 3-3  B. Various functions are shown in  FIG. 24  with the basic logic, as programmed into the microprocessor, being shown in  FIG. 20 .  FIG. 25  shows the timing relationship among the various components. Battery  23 , releasably insertable within the main housing  100 , provides DC power for the PC power board  38 . The battery  23  can be recharged by aligning the contacts  32 ,  33  with the charging cradle  27  contacts as shown in  FIGS. 21-23 . A transformer  29 , as connected to a voltage source, may be connected to the cradle or directly to the power board at jack  36  ( FIG. 4A ). 
     To initially power the security device the slide switch  35  is moved from a first OFF position to a second ON or armed position. A blue indicator  48  advises the user the device is armed ( FIG. 19 ). Red/green indicator  49  advises the user of the extent of battery power with red showing low battery power. At this position ready power is provided for components on board  41 , the activation of such components by the microprocessor  53  (Toshiba 32 bit MCU) to be subsequently described. 
     At the ON position the user initially establishes a communication channel between the Bluetooth® module  51  (Laird Technology-BISMII) and the user&#39;s cell phone ( FIG. 26 ). This pairing is established by depression of the push to talk (“PTT”) button  57  ( FIG. 15 ) so as to pair/interface the cell phone or other communication device with the Bluetooth® module. The depression of the PTT button  57  is just one example to let the microprocessor recognize that a Bluetooth® pairing routine is to be established. It is understood that after this initial pairing routine that Bluetooth® communication will automatically occur upon subsequent arming ( FIG. 20 ,  100 ). 
     Upon pairing, the microprocessor initiates operation of the RECORD module  52  so as to automatically record the ambient noise as picked up by the microphone  50  (Ventromic-OB4010). This recording is on a loop basis, i.e., a continuous 30-second loop recording of the ambient noise is being made. 
     Previously as shown in the set up routine of  FIG. 20 , the user is given the ability to record a personal message, such as the user&#39;s name, location, address, etc. This is provide by the microphone  50 , RECORD switch  45  (Omron), PLAY switch  46  (Omron) and memory  52  (Toshiba-32 MB/64 MB). As such, the user first records the message upon depression of switch  45  and can playback the same upon depression of switch  46 . 
     Also at this time, various other alarms and modules are at a ready position, including the camera module  42  (Toshiba-2MPTCM9200MD), the laser beam unit  43  (Luminex), the LED strobe  44  (Amostech-AL505012AZ) and audio alarm  58  (Ventronic-1.5V). All are awaiting activation as controlled by the microprocessor  53 . 
     Upon movement of the slide switch  35  to its ON/armed position, depression of trigger  17  is possible. Trigger  17  has been pivotally mounted about its lower end within housing  11 . At its  FIG. 2  OFF position the slide lock  37  precludes movement of trigger  17  towards trigger switch  34 . At its ON position the slide lock  37  is displaced from trigger  17  allowing for pivotal movement of trigger  17  into contact with switch  34 . 
     As shown in  FIG. 6 , the free end of trigger is mounted in a spring  24  loaded manner about an elongated nozzle  18 . This tubular nozzle  18  extends into a nozzle housing spray cap  16 . Trigger depression moves the elongated nozzle  18  to its dotted line position as shown in  FIGS. 2 and 6 . As such. valve  23  is opened allowing mace to be discharged from canister  22 , through nozzle  18 . and onto an attacker. The mace may have therein sufficient dye material so as to mark the attacker for subsequent identification. As above, depression of the trigger assembly for mace discharge engages switch  34  which allows the microprocessor to activate a number of components on the component board  41  as shown in  FIG. 20 . 
     As shown in  FIG. 20  the logic circuitry activates the LED strobe module  44 , the laser beam  43 , siren  58  and camera  42  modules. The previously established Bluetooth® pairing enables the microprocessor to connect the user&#39;s cell phone with 9-1-1 or other preselected numbers. The microprocessor then sends the prerecorded voice message to the 9-1-1 dispatcher or other selected number. Concurrently, the last 30 seconds of the ambient audio, having been recorded by module  53 , is saved and subsequently transmitted to 9-1-1 or other selected number. 
     The user can press the PTT button  57  to establish direct communication with the 9-1-1 dispatcher. If not, the messages will be alternately transmitted to 9-1-1 a second time in case the user is disabled ( FIG. 25 ) It is understood that this repeated message transmission also enhances location of the cell phone to be established by known techniques. After this second transmission the alarms are discontinued and an open cell phone communication is maintained with the 9-1-1 police dispatcher. Continuous recording of audio transmitted to the security monitor by the user&#39;s cell phone is established either by the monitor or the record module. It is understood that depression of the PTT button  57  at any time will disengage the alarms and enable direct communication with the police or other security monitor. 
     Included in the power circuitry is an accelerometer  39  (Bosch-BMA150) which will also activate the above alarms in lieu of trigger  17  depression, such when the unit is thrown. jostled or dropped during an altercation. The degree of movement which will activate the accelerometer is chosen as a matter of device design. Accordingly, the device components need not be activated by user depression of the trigger assembly. 
       FIG. 25  illustrates a timing diagram of the various security alarms and components as controlled by the microprocessor  53 . As such the multiple transmissions of the prerecorded message and the ambient audio message will not interfere with each other. The strobe light synchronization will not interfere with the function of the camera module  42  which is taking pictures of the ambient surroundings and storing the same for further recall or transmission to a security monitor. The strobe and siren alarms can also be alternated. As shown in  FIG. 25  and above discussed, the messages are no longer transmitted after 90 seconds as the microphone remains on such that direct communication with 9-1-1 is established without interference with the alarms and messages. Again, these transmissions and alarms can be interrupted by the user by depression of the PTT button  57 . Thus, interference with voice contact or ambient audio is precluded. 
     As shown in  FIG. 26 , the cell phone transmission is linked with at least one cell phone tower. It is understood that the cell phone location can be further established by known techniques as the cell phone is linked with various cell phone towers. Such location is enhanced by multiple transmissions of the prerecorded and ambient messages. 
     Also provided at one end of the housing  11  is a body inflector  14  known as a “Kubaton,” designed to inflect pressure onto sensitive parts of an attacker&#39;s body. Inflector  14  presents threads  15  ( FIG. 12A ) and releasably projects through the aperture  12 A found in the bottom cap  12  housing  11  for threadable engagement with threads in the interior of the housing  11 . As shown, cap  12  includes a battery contact  13  for lower contact with battery  23 . Removal of the Kubaton  14  allows for the housing bottom cap  12  to be removed enabling replacement of the battery and/or mace container  22  within the housing. 
     Accordingly, we have invented a security device which enables the user to establish communication with a security monitor whether purposefully or automatically. The availability of the various weapon type functions, alarms, camera and messages enhances the security afforded by the device. The synchronization among the various devices enhances the effectiveness of the various alarms and message communication with the repeated transmission of these prerecorded and ambient noise messages enhancing the ability to identify and locate the user. 
     It is to be understood that while certain forms of this invention have been illustrated and described, it is not limited thereto, except in so far as such limitations are included in the following claims and allowable equivalents thereof.
