With general reference to
The sensor data transmitted from the personal modules 100 to the fixed communications center 202 is used by emergency services to execute an appropriate and effective response. Upon receipt of information from the personal modules 100, the fixed communication center 202 notifies emergency services and relevant government agencies of the particular toxic substance and the exposure to the substance that has caused, or is likely to cause, harm to humans.
Using the inputs from the databases 101, the sensors 104-109, the RF receiver 110, and the GPS receiver 120, the CPU and software 110 first interpret the raw sensor output data using a sensor output interpretation algorithm 111. Once interpreted, the data from the accelerometer 104, the fluid submersion sensor 108, and the pressure sensor 109 are sent to the injury probability algorithm 112 where it is compared with the reference values from the human injury tolerances database 102. If the injury probability algorithm 112 determines that injury to the wearer of the module 100 is probable, the information is sent first to the recommendation algorithm 114 and then to the module's memory 115. The recommendation algorithm 114 evaluates the type and severity of the probable injury, and outputs a signal to the video screen 121 and speaker 122 that provides the wearer with instructions as to what actions should be taken to mitigate injury. Once the data is stored in the random access memory (RAM) 116 and permanent (i.e. FLASH) memory 117 of the personal module 100 it is wirelessly sent by the RF transmitter 118 to nearby personal modules 100 and the fixed communications center 202. The information can also be downloaded through the hardware output port 119 to a laptop or palmtop computer (not shown).
Once interpreted, the data from the chemical threat sensor 105, the biological threat sensor 106, and the radiological threat sensor 107 are sent to the CBR agent harm probability algorithm 113 where it is compared with the reference values from the human susceptibility to CBR agents database 103. If the CBR agent harm probability algorithm 113 determines that the wearer of the module 100 has been exposed to a harmful dose of a chemical, biological, or radiological agent, the information is sent first to the recommendation algorithm and then out to the module's memory 115. The recommendation algorithm 114 evaluates the type of harmful agent to which the wearer has been exposed, as well as the dose to which the wearer has been exposed, and outputs a signal to the video screen 121 and speaker 122 that provides the wearer with instructions as to what actions he/she should take. For example, depending on the specific threat, the video and audio instructions could indicate if any commonly available substances can be used for decontamination, if the agent should be scraped or washed from the skin or left alone, if the agent is likely to accumulate near the ceiling or near the floor, or a variety of other situation specific recommendations. The recommendation algorithm 114 also takes into account information received from nearby personal modules 100, information received from the fixed communications center, and location data from its internal GPS receiver 120 to provide the wearer with directions for relocation to a less harmful environment. In the case of a chemical release, chemical threat data from nearby modules will allow the recommendation algorithm 114 to direct the wearer to a location with a lower density of the harmful chemical. Data stored in the module's 100 RAM 116 and permanent memory 117 is wirelessly sent by the RF transmitter 118 to nearby personal modules 100 and to the fixed communications center 202. The information can also be downloaded through the hardware output port 119 to a laptop or palmtop computer.
Turning now to
An example of how the RADNS of the present invention can be used as a tool for victims of a disaster and first responders is illustrated in
It can be seen from the map 300 that in the event of such a disaster the various personal modules 100 will each sense, interpret, record, and transmit environmental data that is unique to the grographic coordinates of the particular personal module. With access to a collection of information provided by the sensors in each personal module sensors, the sensors of nearby personal modules 100, and that transmitted from the fixed communications center 202, each personal module 100 will direct its wearer in a direction radial to, and away from the estimated epicenter of the attack.
The map 300 is also representative of one that could be created by overlaying the location and severity data from the individual personal modules 100 over a map of the affected area. Such a map 300 would offer emergency groups 203-206 an improved method for determining the locations of victims and the geographical area covered by the disaster, and would also allow for the implementation of efficient triage. Because emergency response services have access to the probable severity of injury to each wearer of a personal module 100, they can efficiently categorize the victims of the disaster according to medical need prior to arriving at the scene. Responders will immediately seek out the locations of victims whose personal modules 100 have indicated probable, but treatable, injuries, and give lower priority to the areas where signals from personal modules 100 indicate that there is no possibility of human survival. With respect to map 300, emergency responders may be able to treat the wearers of personal modules 100 that lay outside severity ring 302 first, with the understanding that there are likely no survivors residing within severity ring 302. This prospect of advanced triage may ultimately lead to a minimization of victim deaths, and an improvement of rescued patient outcome, when compared to the currently used methods of triage.
The map 300 may also be used by non emergency services 207-209 in order to initiate a long term response to the disaster, or in order to better plan for similar future situations. For example, the FAA 209 may be able to use such information to immediately redirect flights around the site of the disaster, or determine if the occupants and structures of nearby airports have been compromised. Insurance providers 207 may also be able to use the information to immediately begin evaluating damage, and possibly to prevent the payment of fraudulent claims from person's who were near, but not actually affected, by the disaster.
The system (RADNS) can detect, transmit, and interpret information regarding many types of physically or biologically harmful disasters, including those that are man-made, natural, intentional, or accidental. The system is intended to quickly and efficiently transmit useful information to response teams, thereby minimizing both the total number of disaster victims as well as the expenditure of community resources. The personal modules 100 are small devices that can be stowed in a person's pocket, similar to a cell phone or a digital music player. As the miniaturization of sensors and integrated circuits progresses, the personal modules 100 may eventually be worn on the arm, in the manner of a wristwatch.
While particular embodiments of the present invention have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the spirit and scope of the invention. It is therefore intended to cover in the appended claims all such changes and modifications that are within the scope of this invention.
