Abstract

Drowning happens in swimming pools during sudden unexpected events like heart attack, leg cramp or stroke or Sinking of an entertainment boat into the lakes. usually there is no skillful lifeguard in the place of the incident, when a person swimming alone in a private swimming pool or in lakes beyond the eye of a lifeguard. and Even if there is, the process of rescuing takes time and may be harmful for both the drowned person and also the lifeguard. also, rescuing more than one person at the time may not be possible. Coil remote lifeguard is a mobile lace which placed under the water on some compressed coils. By pressing one bottom outside the pool or by swimmer himself using a remote-control device on his wrist, the lace moves upward by release of the coils and shift the person to the surface of the water. Controlling of the coils is via electromagnetic energy which keeps the coils compressed or released.in the lakes this device would be able to rescue all the victims at one moment together. The remote is also sensitive to movement, so that if there is no movement in the hand of the swimmer or boat rider, it starts alarming and if the swimmer/boat rider do not respond because of loss of consciousness, then it automatically starts the process of rescuing. Also, by adjusting the level of the lace, it can prevent falling of people into water or make it in a safe height for kids.

Description

Coil remote lifeguard

The invention generally relates to self – rescuing and, more specifically, emergency dispatch of a drowning person above water.

Swimming in swimming pools and boat riding in the lakes is a desirable entertainment but sometimes It leads to unfortunate accidents. sometimes swimming alone or boat riding for fishing when no one is around, makes it even more risky to take. So lifeguarding has been always an issue.

Rescue device, United States Patent 6475047. An improved rescue device includes a floatation material, a flexible mesh disposed about the floatation material wherein the flexible mesh is in contact with an outer surface of the floatation material, and a bonding material covers the flexible mesh and the floatation material. The floatation material is a closed cell foam material, the flexible mesh is a nylon mesh, and the bonding material is a polyvinyl chloride paint. The rescue device may also include a tow line affixed to one end thereof and a plurality of rings arranged along the length of the tow line. A harness may be coupled to one end of the tow line and a securement device may be coupled to the tow line to retain the tow line in a compressed state. The securement device may be a collar which fastens upon itself by hook and loop fasteners.

Multiple victim rescue device. United States Patent 5480332. A multiple victim rescue device made of at least three elongate buoyant members each of them contain two ends and at least one planar out of the surface. The elongate members can be connected together at their outer planar surface so that one of the elongate members is arranged centrally between the remaining members. A tow line is fixed to one end of the central member and the other end of the central member as well as the ends of the remaining members are provided with either hooks or rings so that the ends can be connected together.

Robotic Drowning Rescue System. United States Patent Application 20150307172. 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 coordinators 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.

Lifeguard alarm system for detecting the state of a swimmer. United States Patent Application 20150116116 A lifeguard alarm system for swimmers, capable of detecting whether a swimmer is moving forward or drowning. The system includes a detecting device, an accelerometer disposed on the detecting device and a computing unit; the accelerometer configured to output respective acceleration values along X, Y, and Z axes of the detecting device and of gravity, the computing unit configured to calculate sum of the squares of the X, Y and Z acceleration values of the accelerometer as a first value and square of an acceleration of gravity as the second value to compare the first value with the second value. The relationship between the first value and the second value can be used to control the warming unit.

Lifeguard alarm system for a swimming pool. United States Patent 8022830. A lifeguard alarm system for a swimming pool contains a sensor device, at least one electromagnetic wave receiver and a host, the sensor device capable of attaching onto a user; wherein the said device detects more than two conditions, a microprocessor in the said device sends a signal to at least one electromagnetic wave receiver disposed around the swimming pool and wirelessly connected to the host, and the host sends out an alarm. Furthermore, it includes a fail-safe mechanism; therefore, when the first detecting mechanism of the device detects that the user is not in the corresponding predetermined dangerous state, to prevent malfunctioning of the first detecting mechanism from creating problems.

Lifeguard Assistant. United States Patent Application 20150036233. The life guard Assistant is pointed to the bottom of the swimming pool of the zone you are covering, allows you to see the bottom of the pool despite all the factors listed above. Mirrors are used to reflect the area of the pool that you want to see the bottom. The invention floats, then it can be made with mirrors going all around it; so no matter where it floats. You can see the pool area from the place the lifeguard is sitting or standing. What does this invention do? It is designed to save human lives from drowning in water. This device can be used in spa tubs, swimming pools, lakes, on water front beaches, and anywhere people take a bath or swim in water. This device aids to save the person drowning in water in a way they go under water undetected by the lifeguard. The lifeguard is distracted for any reason from watching the patrons in the water; the water is murky (because of the bather oils/lotions and/or dirt of swimmers).

There are still so many reports about drowning when a person is alone and has not any access to lifeguard or when a heart attack happens or leg cramps or even unconscious situations like stroke, and also drowning a group of people together in sinking of a boat into the lake. The aim of this invention is to provide a device which has no need to any one for rescuing; in addition to performing the rescue process at the fastest and safest way of possible and has the ability to automatically start when the person is unconscious. It is made of a lace at the bottom of the swimming pool or lakes and whenever it is needed to rescue a person, the coils under this lace release and shift the person at the top of the water.

Due to the important electromagnetic conducting role of the metal in this invention in addition to the location of latches and frame in the water, this device can't perform perfectly in the case of rusting. In the lakes, it needs bigger lace and more powerful coils and latches.

Stainless metals must be used in the process of producing this device and frequent evaluation for rusting has to be planned. In the lakes, we can use more than one lace and group of coils and latches .so the needed power would decrease.

prior innovations were mainly based on human lifeguarding or a device which facilitates the process of rescuing; but still depends on a skillful person to be accomplished. some of them need complex equipment like special materials or robots. The difference between our invention and mentioned life guards is in its simplicity and independency on human lifeguard.

In comparison to lake lifeguards as mentioned before, our invention benefits from the potential of rescuing more than one person at the same time. The process is fast and safe; without any need for specific qualification. The ability to start, alarm and begin an actual rescue process by itself also can be regarded as its innovative step in comparison to other alarm systems that just inform someone to arrive for the rescue.

One big metal frame at the size of swimming pool placed at the bottom of the water (1). At every corner a coil is fixed (7) which compressed by a spool outside the water (6). magnet source (5) conducts its electromagnetic power to metal frame by a metal mobile connector (4). This will make the metal latches (8) getting absorbed magnetically to the metal frame and keep the coils compressed. A lace (2) fixed at the top of the coils.

shows materials needed for construction, which comprises metal frame, lace, cogwheel, metal connector, handle and magnet source, spool, coil and metal latch.

shows compressed coils held by closed latches because of the connection between magnet and metal frame, which comprises lace, handle, metal connector, compressed coil spool and cogwheel.

shows disconnection of electromagnetic power and opening of latches leads to release of the coils and then shift of the lace to top of water, which comprises spool, rope, cogwheel and coil.

The Process of rescuing a drowning person is always stressful and may take lots of time; when every second is vital for a drowning person. Besides; It needs a qualified lifeguard who may not be present at the time of need or in case of drowning of more than one person such as boat riding in the lakes, rescuing in the proper time for all of them usually is not possible or maybe even nobody notices the incident at all. coil remote lifeguard is designed as a portable lace in the bottom of swimming pool or lake which in the case of drowning, can move to the top of the water by mechanical stored power provided by compressed coils under it; therefore, the drowning swimmer or boat riders will be shifted quickly to the surface of the water with no harm and in the fastest way. the remote refers to the manually option of starting the process of rescuing by the swimmer or boat rider themselves in the situation if nobody is around. rescuing by coil remote lifeguard can easily be started by pressing a bottom or moving a handle from outside of the pool by any one with no specific skill.in the cases of swimming or boat riding alone, the swimmer or boat rider/riders can initiate the rescue process by a remote control from a device placed in their wrist. This feature is helpful in some circumstances such as heart attack, leg cramp or boat overturning. Also, the remote is sensitive to the movement, so that if there is no movement for a few seconds, an alarm sound will inform the swimmer/boat rider to turn it off and if the person fails to respond, it automatically starts the rescuing process. This will be helpful in the case of loss of consciousness. Another feature of the invention is the ability of adjusting the height of the swimming pool or lakes in order to prevent falling into it from outside. This would be possible by letting the coils released.

A metal stainless frame (1) placed in the bottom of the water. In every corner of the frame one big powerful coil fixed (7). Coils must be powerful enough to shift the lace and its contents above to the surface of the water.

A lace (2) is placed on top of the coils. The lace is made of metal, aluminum or compressed plastic. It should be hard enough just not to bend by average weight of the persons using that pool/lake. The size of the lace depends on the size of the place which is using for. Metal Latches(8) are placed next to the coils in the frame in order to keep them closed and compressed , as the mechanism will explained later.

A magnet source is placed outside the water (5). A stainless metal connector (4) which is in the water make the connection between the magnet source and metal frame in the water. This connector is movable and Whenever the connection stablished, the metal frame become a temporary magnet and absorbs magnetically the metal latches for holding the coils. The connector movement is controlled by manual handle outside the pool or by remote control from swimmer’s wrist or any other place like a button in the wall.

After pressing the bottom or moving the handle outside (item number 5 in figures), the metal connector detached from the metal frame and so the latches (because of the magnet is no longer connected). The results in release of the coils and their stored energy move the lace to the top of water with any person or objects above it.

After the end of rescuing process and in order to put the lace back in the bottom of the water, there is a spool (6) which spin manually or by a generator providing the energy for compressing the coils again. a cogwheel (3) inside the water will transfer the spool energy to the coils. Spool’s rope is connected to the upper ring of the coils and spinning of the spool leads to compression of the coils.

Metal connector will be placed in its first place to make the connection with magnet source and metal frame again, so Compressed coils will be held by latches magnetically to the metal frame. Latches are fixed from one side to the upper ring of the coils and the other side moves only in one direction because of their hinge; so, when the magnet is connected, latches fix to their exact holes in metal frame.

In summary, after rescuing, the coils would be compressed again by the spool. then by placing the connector to its first place, the frame reconnects to the magnet and latches would be fixed again and hold the coils compressed for the next attempt of rescue.

The advantage of this innovation would be the fast way of rescuing multiple persons at a single time in both manual and remote-control setting even if there is no skillful human around to help. the simplicity of the materials, provides a flexible design in different sizes for every place with possibility for drowning. human lifeguard is not involved in this innovation which make it even safer for both lifeguards and drowned persons in the rescuing process.

A lace is at the bottom of the swimming pool or lake. The material must be made of compressed plastic or lightweight metal such as aluminum in order to tolerate the weight of the person/persons above it. length of the released coil must be equal to the height of the swimming pool or lake. The strength of the coils must be calculated by the average weight of swimmers. Coils fixed to the metal frame from their bottom. coils, spool and a magnet source put outside the water. a button or a manual handle relate to the connector is placed somewhere reachable and accessible outside the pool.

Examples

The average weight of people using the deep part of a swimming pool is 70 Kg by considering lowering of the weight in the water based on Arashmidos rule. Average number of swimmers is 10 persons. The height of the swimming pool in the deep part is 3 meters and a person usually doesn’t sink into water more than 2 meters. in order to shift these persons to the surface of the water we must first calculate the energy needed to do that.

[Math. 1 W= f.d.cosα Work formula: f=weight(Kg*10) d=distance cosa=1

W= 700*10*2*1=14000 j

After dividing this energy to the number of coils, we calculate the energy that each coil must contain. By using second formula for coils named Hook rule, the needed coils with special K obtained which differ from coils to coils and shows the strength of a coil.

U=1/2 kx2 = U=coil potential energy k=instant x=difference between heights of compressed coils and released

14000/4 = 3500 j each coil

3500=1/2*k*22 K= 1750

In public and private swimming pools as a lifeguard .and also as a preventer of falling down into the water between the swimming sessions by adjusting the height of the lace and letting the coils released.

As lifeguard In the entertainment lakes for boat riding and fishing.

Remote control could be used specially in private swimming pools for swimming alone, and for patients with high risk for sudden medical events and also for boat riders in the lakes.
