Abstract
A system remotely monitors a potential drowning victim and remotely and passively detects one or more drowning indicia. Upon detecting one or more drowning indicia, the system acquires location coordinates of the victim and activates a self-propelled robotic submersible, which travels to the victim's location and uses one or more sensors to position itself directly below the victim in the body of water. When the sensors have confirmed the position of the submersible directly below the victim, the submersible initiates the rescue operation by lifting or floating the victim above the surface of the water. The submersible then transports the victim to an area where he/she can be resuscitated and receive medical attention.
Description
- The present invention relates to the field of devices and methods for detecting and responding to situations in which individuals are or may be drowning in a body of water. More particularly, the present invention relates to an apparatus and method by which drowning prevention measures are passively deployed—that is, deployed without any action or involvement on the part of either the potential drowning victim or a bystander.
- According to the Centers for Disease Control and Prevention (CDC), about ten people die from accidental drowning every day. Drowning ranks fifth among the leading causes of unintentional injury death in the United States. Even when drowning incidents are non-fatal, more than half of drowning victims require hospitalization or further care. Non-fatal drowning injuries often include brain damage with associated long-term disabilities, such as memory problems, learning impairments, and/or permanent loss of motor functions.
- The prevention of drowning and effective intervention in potential drowning situations involve two technical challenges: (1) early detection of potential drowning circumstances, with minimal “false alarms,” and (2) rapid and effective responsive measures to re-enable the victim's respiration by either lifting/floating the victim above the water or draining the water body in which the victim is drowning.
- With respect to drowning detection, the art in this field has focused on four types of methods: (a) detection of a victim's subsurface motions by microwave, optical and/or sonic sensors, (b) detection of failing vital signs, such as cardiac arrest, through a special wristband worn by the victim, (c) activation of a distress signal by the victim him/herself, and (d) observation of the distressed victim by a bystander. Of these methods, only the first can truly be considered a “passive” detection system, since the other three methods require one or more active steps or precautions by the victim or a bystander. In circumstances where a solitary drowning victim has become non-responsive or panic-stricken, these “active” methods of drowning detection will prove ineffective.
- Furthermore, the “passive” drowning detection methods known in the art erroneously target frantic subsurface motions as supposed indicia of drowning. As experts in maritime safety have documented, however, a drowning victim is typically nearly motionless, upright in the water and not kicking his/her legs to keep him/herself afloat. Since the victim's energy and attention is totally absorbed in gasping for air each time his/her mouth bobs up above the water, he/she is often unable to call out, wave for help or even reach for a lifeline.
- With respect to rapid and effective responsive measures once a drowning situation is detected, one type of method is to quickly drain the body of water in which the victim is drowning. This type of method is taught in our co-pending U.S. application Ser. No. 14/058,979, the disclosure of which is incorporated herein by reference. While rapid drainage methods can be effectively implemented in relatively small bodies of water, such as shallow wading pools for small children, they are not suited for larger water bodies.
- Several U.S. patents, including U.S. Pat. Nos. 4,129,905, 4,747,168, 6,127,930, and 7,479,891, disclose swimming pool rescue systems based on an inflatable float and/or netting rising from the bottom of the pool to lift/float the victim above the water. Since these systems lack a means of localizing the rescue float/net below the drowning victim, the inflatable component must encompass the entire pool surface, as well as lifting other objects and/or persons in the pool, resulting in an inflation/deployment time interval likely to exceed the critical window for effective rescue before the victim stops breathing. Also, at the finish of the supposed “rescue” by these systems, the victim is left, with his/her lungs full of water and in respiratory distress, lying helpless on a huge mattress too bulky to be dragged out of the water by a single bystander.
- Moreover, with one exception, none of the patented “whole pool” inflatable rescue systems are passively deployable, because each requires activation by the victim, a bystander or by a wristband worn by the victim. While U.S. Pat. No. 6,127,930 does describe a “whole pool” mattress inflated in response to microwave motion sensors disposed around the pool perimeter, its system is designed to be triggered by any motion within the pool, and so is usable only as a monitor during pool “downtime” and must be disabled during normal pool use (column 4, lines 24-26).
- Consequently, the art in this field is distinctly lacking in a system which:
-
- Detects documented indicia of drowning remotely—that is, without contact or interaction with the victim and/or bystanders—and passively—that is, without the aid of active steps, measure or precautions taken by the victim and/or bystanders;
- Rapidly, effectively and passively responds to a detected drowning situation by lifting or floating the victim with a lift/floatation means localized to the victim's position, such that the lifted/floated victim can be moved out of body of water to a place where he/she can be given medical attention.
- The following definitions apply to the present invention as described and claimed herein:
-
- “drowning” means a condition in which a person in a body of water is unable to maintain their body in an orientation allowing for sustained respiration;
- “victim” means a person in a body of water whose behavior is indicative of drowning;
- “bystander” means a person able to observe the victim in the drowning condition, either by direct visual contact or remote monitoring;
- “drowning indicia” means any one or more of the following signs of drowning: (i) victim not using his/her legs to support his/her head above the water, (2) victim's arms pressing down on the water surface to leverage his/her head above the water, (3) victim's nose and mouth at water level bobbing up and down, (4) victim's body floating nearly motionless upright or leaning back in the water, (5) victim's eyes staring, glassy, unfocused or closed, (6) victim's hair covering their forehead or eyes, (7) victim trying to swim but making no progress through the water, (8) victim in respiratory distress with hyperventilation or gasping for air, (9) victim in cardiac distress, with elevated heartbeat, (10) victim verbally unresponsive, or (11) victim's mouth open or gulping water;
- “active” describes a system or device, the operation or deployment of which requires one or more affirmative steps, measures or precautions taken by a victim or a bystander;
- “passive” describes a system or device, the operation of deployment of which does not require any affirmative steps, measure or precautions taken by a victim or a bystander;
- “passively” describes an action or operation of a system or device which does not require any affirmative steps, measures or precautions taken by a victim or a bystander;
- “remote” or “remotely” describes an action or operation of a system or device in which the action or operation does not involve contact with or interaction with a victim or a bystander;
- “biometric” describes physiological characteristics of a person, including facial features and patterns, size, shape and patterns of body parts, heart rate, breathing rate, DNA, and voice patterns;
- “biometric identification” and “biometric tracking” mean, respectively, the identification and tracking of an individual based on biometric data, including the use of computer implemented algorithms or software to match an individual's measured biometric data with one or more biometric databases;
- “behavioral” describes the actions and behavior of a person, including movements, bodily orientations, gestures, signals, sounds, speech, and facial expressions;
- “localized” describes an action, operation or device within a distance of two feet around the perimeter of a victim's body:
- “self-propelled” means capable of locomotion either on land or in the water and having one or more sources of power to effect and sustain such locomotion.
- The present invention is a system which remotely monitors a potential drowning victim and remotely and passively detects one or more drowning indicia, which may be behavioral indicia, biometric indicia, or a combination of both. Upon detecting one or more drowning indicia, the system acquires location coordinates of the victim and activates a self-propelled robotic submersible, which travels to the victim's location and uses one or more sensors to position itself directly below the victim in the body of water. When the sensors have confirmed the position of the submersible directly below the victim, the submersible initiates the first stage rescue operation by lifting or floating the victim above the surface of the water.
- The first stage rescue operation is effected by the submersible in a floating mode or a lifting mode. In the floating mode, the submersible deploys an inflatable floatation device, which is stored folded and uninflated within an internal float compartment of the submersible prior to deployment. Upon initiation of the first stage rescue in the floating mode, the access doors to the float compartment are opened, and compressed air/gas is injected into the inflatable floatation device so as to expand and unfold it. The inflated floatation device rises beneath the victim to the water surface and supports the victim above the water. The floatation device is tethered to the submersible, so that the submersible can tow it with the victim aboard through the water.
- In the lifting mode of the first stage rescue operation, the submersible uses a platform on its upper surface to lift the victim by ascending from directly beneath the victim to the water surface, so that the platform supports the victim above the water. The ascent of the submersible in the lifting mode can be effected either by upward propulsion and/or by the expulsion of ballast from one or more ballast tanks within the submersible.
- After the first stage rescue operation is accomplished, in the second stage rescue operation the victim is either towed on the floatation device by the tethered submersible or carried on the submersible's platform out of the body of water or a border thereof where the victim can receive resuscitation and medical attention.
- The drowning detection component of the system remotely and passively acquires victim data, comprising behavioral data and/or biometric data, which are compared with a compiled set of documented drowning indicia. This comparison can be implemented by a computer or microprocessor using algorithms or software to match the victim data with the drowning indicia. The detection component remotely and passively acquires the victim data using microwave, infrared, optical, sonic, or ultrasonic observations and measurements, or a combination thereof
- In situations in which the present system is monitoring a body of water in which there are multiple persons, the system can use biometric data to distinguish different individuals and separately track them. In this way, even if a potential drowning victim is surrounded by other swimmers, the system can pick him/her out of the crowd and detect drowning indicia on an individualized basis.
- The drowning detection component can be incorporated in the submersible, or it can constitute a separate unit which communicates wirelessly with the submersible.
- The foregoing summarizes the general design features of the present invention. In the following sections, specific embodiments of the present invention will be described in some detail. These specific embodiments are intended to demonstrate the feasibility of implementing the present invention in accordance with the general design features discussed above. Therefore, the detailed descriptions of these embodiments are offered for illustrative and exemplary purposes only, and they are not intended to limit the scope either of the foregoing summary description or of the claims which follow.
-
FIG. 1 is a schematic diagram of one of the preferred embodiments of the present invention; -
FIG. 2A is a perspective view of a self-propelled, robotic, submersible in accordance with one of the preferred embodiments of the present invention; -
FIG. 2B is a perspective view of a self-propelled, robotic, submersible in accordance with one of the preferred embodiments of the present invention; and -
FIG. 3 is a flow chart of the operative process of the preferred embodiments of the present invention. - Referring to
FIGS. 1 , 2A and 2B, one embodiment of thepresent invention 10 comprises adetection device 11, which monitors thevictim 12 and remotely and passively acquiresvictim data 13, comprising behavioral and/or biometric data. The detection device compares thevictim data 13 with a compiled set of documented drowning indicia. This comparison is implemented by acomputer system 14 in thedetection device 11, using software to match thevictim data 13 with the drowning indicia. Thedetection device 11 remotely and passively acquires thevictim data 13 using microwave, infrared, optical, sonic and/or ultrasonic observations and/or measurements. - Upon detecting one or more drowning indicia, the
detection device 11 acquires location coordinates of thevictim 12 and wirelessly communicates the victim's location coordinates to a self-propelledrobotic submersible 15. Therobotic submersible 15 thereupon travels to the victim's location and uses apositioning sensor 16 to position itself directly below thevictim 12. Once so positioned, the submersible 15 initiates the first-stage rescue operation by deploying aninflatable float 17, which, prior to deployment, had been stored folded and uninflated within aninternal float compartment 18 of the submersible 15. - The
float compartment 18 is accessed throughaccess doors 19, which open to release thefloat 17 as it is inflated by compressed air/gas from atank 20 within the submersible. As theinflated float 17 rises from thecompartment 18, it remains tethered to the submersible by atether line 27. Theinflated float 17 then rises beneath thevictim 12 to lift him/her to the water surface and support him/her above the water. - The
robotic submersible 15 uses itssensor 16 to determine that thevictim 12 has been secured in thefloat 17, and then initiates the second stage rescue operation by towing thefloat 17 with thevictim 12 out of the body of water or to a border, such as a beach area or pool side, where thevictim 12 can be resuscitated and receive medical attention. - As shown in
FIG. 2A , the submersible 15 can alternately be configured with alifting platform 21 on its upper hull. In this mode, the submersible 15 lifts thevictim 12 by ascending from directly below him/her up to the water surface so that theplatform 21 supports thevictim 12 above the water. The ascent of the submersible 15 is effected by upward propulsion and/or by expulsion of ballast from aballast tank 22 within the submersible. The compressed air/gas tank 20 provides the force to expel ballast from theballast tank 22. - As depicted in
FIGS. 2A and 2B , the submersible 15 can have a propulsion system comprising eitherpropellers 23 orwater jets 24, with the latter using awater inlet 25 in the bow of the submersible 15. Vertical movements of the submersible 15 are controlled by theballast tank 22. An on-board microprocessor 26 contains the submersible's operational programming and interacts with thedetection device 11. - As shown in
FIG. 3 , the drowning detection and rescue process 100 begins with identification and tracking of apotential drowning victim 101. After acquiringvictim data 102, the victim data is compared with the documenteddrowning indicia 103. If no match is found, the process returns to thedata acquisition mode 102. - If a match is found, rescue operations are initiated 104, pursuant to which the victim is lifted or floated above the
water 105. Optionally, alert mechanisms, such as a lights, audible alarms, and/or telephonic/text messaging to emergency contacts, can also be activated. Next the process confirms that the victim has been secured above thewater 106. If not, the lift/float step is repeated 105. If so, the victim is towed to shore or dry-ground 106, where he/she can be resuscitated and receive medical attention as needed. - Although the preferred embodiment of the present invention has been disclosed for illustrative purposes, those skilled in the art will appreciate that many additions, modifications and substitutions are possible, without departing from the scope and spirit of the present invention as defined by the accompanying claims.
