Title of Invention: EMERGENCY DEVICE The applicant applies for the grant of a patent for the invention described in the accompanying complete patent specification: The following is a full description of the invention including the best method of performing the invention, known to us: 2 EMERGENCY DEVICE [0001] The present invention relates to an emergency device and in particular to an emergency device including a location device and a repellent to animal attack. BACKGROUND TO THE INVENTION [0002] Boating can be dangerous, and in the case of an emergency it is desirable to be able to contact help as quickly as possible. Many different problems can occur, an engine can fail, a mast can break, a collision, a fire, or in the case of a storm there may be a serious risk of the boat sinking. In shore, people can be foolish and crash vessels in harbour causing serious damage, particularly if alcohol is involved. In any emergency situation a person may need to enter the water and be rescued. [0003] If a person is lost at sea or even a short distance from shore, no one may know that the person is in difficulty and if they are looked for it may be very difficult to locate them. High seas impair visibility, as do wind and rain, sea spray and of course in low light conditions or at night. In bad weather a person may be separated from their vessel making it even more difficult to find them and bring them to safety. Tragic accidents and loss of life can occur easily in water and it is very difficult, once a person loses consciousness, to locate the person. The longer rescue takes, the less likely successful resuscitation may be, and the result may, sadly to be the death of the person. [0004] On land, a person may be injured, lost in the bush and difficult to see or locate. The person may be vulnerable to animal attack until they are rescued being prone on the ground. Finding a person quickly is very important as is trying to keep them safe from predators, in countries that have wild animals. [0005] For safety, EPIRBs should be carried by all vessels on open water so they can be activated if help is required. Increasingly, similar personal location devices are becoming required for people travelling in remote land locations too, such as surveying mine sites. For EPIRBs, an antenna enables the emergency signal to 3 be transmitted to the relevant authorities. A Global Positioning System ("GPS") allows for location data of the person or vessel in distress to also be available to the authorities. EPIRBs can be attached to a person so that rescuers have the best chance of locating the person and rescuing them as quickly as possible. [0006] In an emergency situation, a person may be forced to enter the water to await rescue. The person should be wearing a life jacket to assist with buoyancy but being in the water can present more immediate dangers. For example, in tropical waters the person in the water can attract sharks, which will pose an immediate and serious threat to the life of the person. If a person in the water is found by the shark and the person is unable to remove themselves from the water there is very little the person can do to prevent a shark attack and probable death. [0007] It would be highly desirable to have an improved emergency device that can send a distress signal and deter animals from approaching. [0008] Throughout the specification the example of use of the emergency device on the sea is given, but clearly the emergency device is applicable to any emergency situation. The emergency situation may include where a person enters the water. For example, estuaries can be hunting grounds of sharks and crocodiles as can river mouths, and so it is not intended that the emergency device invention be limited to use in the sea. Where a person is on land, the location beacon may send a message to the nearest land based emergency centre, to be alerted to an emergency situation and the location of the person. Further sounds issued can assist to deter animals and to locate the missing person in a land emergency. There are numerous variants and forms of the invention which are intended to fall within the scope of the invention herein defined. [0009] For clarity, any prior art referred to herein, does not constitute an admission that the prior art forms part of the common general knowledge, in Australia or elsewhere. [0010] It is an object of the present invention to provide an emergency device that at least ameliorates one or more of the aforementioned problems of the prior art.

[0032] The emergency device may include a Sound Emitting Device ("SED") to assist to locate the person. The SED may assist to locate a person in water, including under the water. The SED may make any suitable detectable noise. Preferably, the emergency device includes one or more of: Personal Locating Beacon; animal deterrent; and Sound Emitting Device. The function of each of these features may overlap and could be produced by a single article within the device. Where the device is used out of the water the SED may produce a sound suitable to deter land animals who may present a danger. A PLB, SED light or 11 combination may be included in the device. The animal deterrent may produce a high, loud or otherwise unpleasant noise suitable to deter the target animal or animals. [0033] Preferably, in one form of the invention, the emergency device provides locating data and shark protection to a person in an emergency who has needed to enter the water. Preferably, the emergency device is suitable for use in tropical waters where a person may be in the water for a considerable length of time and sharks pose a greater risk, than dying of exposure. [0034] Preferably, a sound or "ping" is emitted by the device. The sound or "ping" may be part of a personal location beacon or part of the animal deterrent or both. The sound or "ping" may be useful to locate a person in an emergency. The sound or "ping" may be continuously emitted. The sound or "ping" may be continuously emitted after activation. The sound or "ping" may be the animal deterrent signal. Repeated sounds are useful for echo location or use of radio location devices as would be readily understood. [0035] A quiet sound or "ping" may be continuously emitted from the device, on activation, to provide a sound that emergency services can listen for when locating a person. The sound may act as a personal location device, whereby the sound or regular "ping" can assist to locate a person though use of radio equipment. [0036] The sound or "ping" may assist to find a person who is underwater. Use of a regular sound may enable a person to be found underwater who cannot be seen due to low visibility. [0037] The sound or "ping" may be used to locate a person on land by use. The sound may be a repeated noise readily detectably by receiving equipment of emergency services. The sound may be a regular "ping" of 600 Hrz. In other forms of the invention the sound may be a very loud noise of a suitable high frequency useful to deter warm blooded animals due to the discomfort to their ears of the 12 loud, high frequency sound. Preferably, the animals deterred are chosen from the group: shark; crocodile; dingo; wild dog; wolf; lion; tiger; wild cat; hippo; rhino; kangaroo; bear; and large bird species including emu and cassowary. Preferably, a combination of signals are emitted to deter the target animals. In one form of the invention a sound may be emitted and the sound is a deterrent to animals. Preferably, the animal deterrent is chosen from the group: sound; smell; light; movement or combination thereof. [0038] The form of the invention may be varied to suit the location of use and the nature of the animals to be deterred. It is envisaged that a number of variants to the device will be available for sale which may be used by different people in different situations. In one form of the invention, the device itself may include a range of deterrents operable by the person for use to deter different types of animal. Other options could also be included such as varying the volume of sounds, and the pitch to deter different animals, in different situations.

DETAILED DESCRIPTION OF THE DRAWINGS INCLUDING A BEST METHOD [0058] Referring to Figures 1 to 3, a first preferred embodiment of the invention will be described, where emergency device 1, has housing 10 within which the EPIRB electronics are enclosed, as well as a power source, neither shown. The power source is one or more rechargeable batteries, as would be well understood in the art. Use of rechargeable batteries improves the usability of the device for both recreational boaters as well as people who work on the water or the emergency services. [0059] Housing 10 as shown is made of strong plastic but metal or other strong waterproof materials could be used instead. Housing 10 is formed so that when closed housing 10 is waterproof and prevents water getting into the electronics and power source of the invention. Housing 10 is shown as somewhat cylindrical but other shapes including a square or box shaped may also be used. [0060] The EPIRB electronics are of a standard form, with a GPS for sending locating data on activation in the case of an emergency. Housing 10 has top 12 and base 14. Top 12 is used mostly for the EPIRB transmission whereas base 14 includes the parts necessary for deterring sharks, as described further below. Other emergency devices can be included in the invention, such as a PLB personal locating beacon or SED sound emitting device to further improve the emergency data provided to the emergency services but are not illustrated for this form of the invention. [0061] Attachment 16 includes a spool of cord on a bracket, neither labelled, for attaching emergency device 1 to the person, or an object. In use the cord can be 15 used to tie emergency device 1 securely around the person, or to their clothes or life jacket, for example. Base 14 is made up of shark deterrent antenna 18, and brackets 20 and 22, with part 24 between them. Brackets 20, 22 and part 24 as shown are made of steel bent to form a leg shape. Other suitable shapes or materials may be used. The particular shape of brackets 20 and 22 are useful to wind shark deterrent antenna 18 around as the flared shape acts against unravelling. [0062] Shark deterrent antenna 18 is an electronic wire through which a charge can be caused to pass. Power is supplied by being wired to batteries stored within housing 10. The electric charge is generated from the power source between two electrodes, creating an electric pulse. The mild electric pulse is emitted into the water which sharks find unpleasant. The electric charges is too mild to cause discomfort to the person using the device. [0063] On off switch 26, on part 24 enables shark deterrent antenna 18 to be turned on and off as desired, to save the battery when not in use. Similarly, lever 28 enables activation of the EPIRB to send the distress signal through EPIRB antenna 30. Lever 28 for activation of the EPIRB can be opened by accessing switch 32, through use of hinge 34 lifting away from part 36. The requirement to lift lever 28 to access activation switch 32 assists to prevent accidental activation of the EPIRB. The EPIRB should only be activated in an emergency as activation will cause a distress signal and location data to be transmitted to the emergency services. A search and rescue team should be sent as soon as the signal is received and so it is imperative that the EPIRB is not activated accidently, only in a genuine emergency. A light, in the form of Light Emitting Diode ("LED") 38 is included on top 12 which is illuminated when the EPIRB is activated. [0064] Screws 40 and 42 between top 12 and housing 10 enable access to the batteries and EPIRB electronics, not shown. Screws 44 and 46 similarly allow access between base 14 and housing 10. Screws 40, 42, 44 and 46 are standard screws but could be replaced with other suitable fixings. Importantly housing 10 is waterproof when screws 40, 42, 44 and 46 are closed.

16 [0065] In an emergency, a person may be on a boat which starts to sink, the person quickly makes sure they are wearing a life jacket and locates emergency device 1. Emergency equipment is generally kept in a predetermined location on a vessel and labelled accordingly so it can be readily found in an emergency without undue delay. On getting hold of emergency device 1, the person will activate the EPIRB by lifting lever 28 and use of switch 32. On activation LED 38 will be lit to show that the EPIRB signal is being transmitted to the emergency services via antenna 30. The person can then attach emergency device 1 to himself preferably, by use of the spool of cord of attachment 16. Alternatively, if the person is going to cling to an object he could attach emergency device 1 to the object and then himself to the object. Preferably, though emergency device 1 is attached to the person so as to minimise the risk of the person and emergency device becoming separated. The person could attach emergency device 1 to themselves before activating, whichever in more convenient in the particular circumstances. [0066] At this point, if the person is forced into the water and it is suspected that the water may contain sharks, action can be taken to try to deter the sharks from approaching. Shark deterrent antenna 18 can be unwound from brackets 20 and 22 to float down into the water close to the legs of the person. Shark deterrent switch 26 can then be turned on so that a mild electric signal is sent out. Sharks find this interferes with their Ampullae of Lorenzini which ordinarily they use to detect the weak electric charges given out by other sea creatures allowing the shark to find and probably eat them. To avoid this happening to the person the mild electric signal sent out by shark deterrent antenna 18 is unpleasant to the shark and confuses it so the shark is deterred from staying within the range of the signal. Sharks will therefore be deterred from approaching, despite the attractant of the splashing in the water of the person. [0067] Referring to Figures 4 to 7, a second most preferred embodiment of the invention is described, with additional and beneficial features to the first. Using similar reference numerals to the first emergency device 101, has housing 110 within which the EPIRB electronics are enclosed, as well as a power source, 17 neither shown for clarity of illustration. Housing 110 as shown is made of strong plastic but metal or other strong waterproof materials could be used instead. Housing 110 is a generally a cuboid shape as illustrated but other forms and shapes could be used instead. Housing 110 is formed so that when closed housing 110 is waterproof and prevents water getting into the electronics and power source of the invention. The waterproof nature of housing 110 is important to maintain the functionality of emergency device 101 in the water. [0068] The EPIRB electronics are of a standard form, with a GPS for sending locating data on activation in the case of an emergency, as described for the first embodiment. Housing 110 has top 112 for the EPIRB transmission. A PLB personal location beacon should be included and or a SED sound emitting device in emergency device 101 to further improve the emergency data available to the emergency services. [0069] An attachment may be included although not shown here, as for emergency device 1, including a spool of cord on a bracket, for attaching emergency device 101 to the person, or an object. In use the cord can be used to tie emergency device 101 securely around the person, or to their clothes or life jacket, for example. The attachment part can be omitted or changed in format to suit the person using the emergency device. [0070] Housing 110, different to the first preferred embodiment, includes door 121 in base 114 leading to a waterproof area within the housing, not labelled. Door 121 is important as it is through door 121 that arm 123 can extend on activation, from the arm part of the housing. Door 121 as illustrated is formed in the rounded corner of base 114. It is particularly convenient to have arm 123 extend straight down through door 121 but other positions could, possibly, be used, in other forms of the invention. Door 121 is hinged (not labelled) to flap open to allow 123 to be pulled out, and move under gravity out of housing 110. Other forms of closure could be used instead. As illustrated arm 123 is telescopic and the three sections 123a, 123b and 123c which can be pulled out to extend into the water on activation. Tip 123d of telescopic arm 123 is discussed further below.

18 [0071] Activation of emergency device 101 can occur by lifting activation lever 128 to access and operate the switch below (not shown). The requirement to lift lever 128 to access the activation switch assists to prevent accidental activation of the EPIRB. The activation can also be used as a backup to other forms of activation should they develop a fault for some reason. The EPIRB should only be activated in an emergency as activation will cause a distress signal and location data to be transmitted to the emergency services. A search and rescue team should be sent as soon as the signal is received and so it is imperative that the EPIRB is not activated accidently, only in a genuine emergency. A light, Light Emitting Diode ("LED") is included on top 112 which is illuminated when the EPIRB is activated. [0072] EPIRB antenna 130 is adapted to send out the emergency signal on activation which can be detected by the authorities so that search and rescue can be initiated. Antenna 130 and the EPIRB electronics for transmitting the location data from the GPS are of a known form as would be readily understood by a person skilled in the art. Where other locating devices are included the information will can be communicated directly to the emergency services. [0073] On activation, the person can open door 121 so as to be able to pull out arm 123, by use of the telescopic parts 123a, 123b, and 123c. Spring 150 assists arm 123 to leave the waterproof housing (not labelled) once door 121 is opened. Sprint 150 is bias to uncoil once the pressure of closed door 121 is removed to push arm 123 through the opening below base 114. Tip 123d therefore extends below the level of open door 121 which allows for telescopic arm 123 to readily be extended so that parts 123a, 123b, and 123c are fully extended. Arm 123 can also be used in the partially extended state as the electrodes extend the full length in the contracted or extended state. Shark deterrent arm 123 would therefore work at least to some extend to deter sharks in the retracted state provided tip 123d is in the water. The shark deterrent part of emergency device 101 may not be activated until needed, to save battery when not in the water or not in danger from sharks. Or in another form of the invention pulling out of arm 123 causes activation of the EPIRB and or any other emergency beacons, and or the shark deterrent itself. An 19 automated device is preferred, however, there may be different forms to save battery use, for example for use by weekend sailors. In the illustrated invention on activation the mild electrical pulse is generated from within the device and emitted through arm 123. Electrodes are included in parts 123a and at the tip 123d and a charge passes between these two points. As can be seen in particular in Figure 7 three dimensional electric fields are generated in this way about the electrodes to extend around the person, in the water. Wires 152 and 154 conduct the electrical charge from shark deterrent batteries, represented by label 155. Batteries 155 are intended to be rechargeable batteries. [0074] Wires 156,158 and 160 likewise provide power from EPIRB batteries represented by label 162. Wire 156 provides power from EPIRB batteries 162 to antenna 130. Wire 158 runs between batteries 162 to EPIRB on/off switch 128 and wire 160 runs to an LED light (not shown) which illuminates when emergency device 101 is activated. [0075] Water level 164 illustrates emergency device 101 floating due to the integral buoyancy and generating the electric field into the water. The person (not shown) would be close to emergency device 101 and as such would be close to our within the strongest electrical charge. It is this point that the sharks will most avoid and so should not investigate the person with their inviting legs dangling in the water but instead will move on to another part of the water. [0076] Again in an emergency, a person may be on a boat which starts to sink, the person quickly makes sure they are wearing a life jacket and locates emergency device 101. Emergency equipment is generally kept in a predetermined location on a vessel and labelled accordingly so it can be readily found in an emergency without undue delay. On getting emergency device 1, the person will activate the EPIRB by lifting activation lever 128 and use of the waterproof activation switch. On activation the activation the LED will be lit to show that the EPIRB signal is being transmitted to the emergency services via antenna 130. The person can then attach emergency device 101 to himself preferably, by use of the spool of cord as described for the first embodiment above.

20 [0077] Referring to Figures 8 to 16 a third embodiment of the invention is disclosed, similar to the first and second with similar reference numerals to the first and second emergency devices, emergency device 201, has housing 210. Housing 210 is made of top 212 and bottom 214 which together form the strong, sleek and waterproof housing for containing the functional parts of device 201. Housing 210 is specialling designed to house all the components of the device is this sleek and smooth way, particularly beneficial during use. The sleek and smooth design is most beneficial to prevent accidents due to tangling of wires or catching of the device on other items, during deployment or use. [0078] Activation button 216 is conveniently positioned on top 212 for ready activation in the case of an emergency. Activation button 216 requires a strong press for activation. Other forms of activation could equally be used. Test buttons can also be included here to test for power or that the other parts of the device are working properly, through testing the circuit in the usual fashion. [0079] The EPIRB electronics as illustrated in Figures 12 and 13 with a GPS for sending locating data on activation in the case of an emergency, as described for the first and second embodiments. The accuracy and nature of the data sent to the emergency services can now be very accurate so that rescue services can be directed to go to the area indicated by the GPS locating data from the emergency device to find the person in an emergency situation. [0080] As shown in Figure 13 the parts of EPIRB printed circuit board ("PCB") PCB Board 230 are installed, sized to fit conveniently within housing 210. Figure 14 shows alert PCB arrangement 240 and batteries 242 to provide power to the device. LED light 244 for activation button 216 is installed in the usual fashion. Clearly, a variety to the arrangement and colour of LED light 244 could be made. For example, in one form of the invention there could be multiple lights to indicate the status and activation of the device. [0081] GPS Chip 246 is of a known form to provide location data from the GPS network. It is envisaged that the GPS network will be replaced in time with another 21 system with a similar function. The device can then be adapted to work with the new system. The location data is transmittable through the internal antenna and the other PCB components 248 and 250 as would be readily understood by a person skilled in the art. [0082] Speaker 260 is further installed with PCB component and a further battery 264 on alert PCB with charge points 270 and 272. Speaker 260 is adapted to produce a regular sound suitable for the application of the device. A regular "ping" is most useful but other sounds could be used instead. [0083] Batteries 242 and 264 are standard rechargeable batteries, other types could be used instead. It is envisaged that a solar recharge system could be used to charge or keep topped up the power of the batteries in some forms of the invention. [0084] All the components fit neatly with housing 210 ready for activation and use when required. [0085] As in the other embodiments in an emergency activation of device 201 through pressing button 216 causes EPIRB 230 to be activated. In this way a distress beacon complete with location information is sent to be received by the emergency services. An internal power supply enables EPIRB 230 to send the signal by means of an internal antenna. At the same time an activation of button 216 also causes the shark deterrent to be activated as created by PCB arrangement to be activated. Whereby, an electrical charge is created between charge points 270 and 272. The localised electrical charge is sufficient to deter the approach of a shark or other similar creates. [0086] At the same time on activation a "ping" of 600Htz is emitted which can be readily detected by the emergency services, even underwater. If a person is lost underwater, the sound device issued by speaker 260 will prove vital to quickly locate the person. It may be possible in this way to locate a person underwater in time to resuscitate them and save their life.

22 [0087] Other forms of the invention are envisaged such as for land use where a high frequency sound emission may be made to deter the approach of animals. A very loud and or high pitched sound will deter many warm blooded animals as they find the sound unpleasant as we do. A very high pitched sound, out of our hearing range could be used to deter some animals. The particular sound, frequency and loudness will depend on the threats in the area a person may wish to use the device. A range of settings can be included a person can chose between these so as to choose the most suitable deterrent for the environment. [0088] If the water is thought to contain sharks, action can now be taken to try to deter the sharks from approaching. Shark deterrent arm 123 can be extended into the water to extend the area into which the electrical pulse is emitted. The shark deterrent switch, a waterproof on and off switch can then be turned on so that a mild electric signal is sent out and again this deters the shark from the area so they move away rather than investigating further. [0089] The inventor has developed a clever means of deterring sharks and alerting emergency services. In particular use of the telescopic arm is a resilient way to deter sharks, that can be varied to extend the zone of protection. It is expected that the device, once available will become the required standard for boat users in hazardous tropical waters to reduce the risk of shark attack of a person waiting to be rescued. INDUSTRIAL APPLICABILITY [0090] The invention is intended to be industrially manufactured and assembled before supply to wholesalers or retailers for sale to the ultimate consumer. [0091] It will be apparent to a person skilled in the art that changes may be made to the embodiments disclosed herein without departing from the spirit and scope of the invention in its various aspects.
