Description:
FIELD OF THE INVENTION 
       [0001]    This application relates to devices used in search and rescue of vessels and persons in distress, especially in a marine environment. More particularly, the present application provides an emergency beacon having a high-intensity pattern of light which incorporates both a radially symmetrical and omni directional/beam electrically-powered, LED light emitting electronic visual distress signaling device (eVDSD) incorporating a wireless transmitter and GPS transmitter that can interface with the internet using a cell phone adaptor to enable mobile handheld smartphone application (apps) devices to alert emergency situations and locate vessels and persons in distress. This device can be used as a replacement for pyrotechnic flares utilized in search and rescue of vessels and persons in distress, especially in a marine environment. 
       BACKGROUND OF THE INVENTION 
       [0002]    A vast assortment of signaling lights, including search and rescue devices for the use on vessels in distress, have been used for many years. The use of pyrotechnic flares has been in the past the most commonly used for distress signal devices. Pyrotechnic flares are exceptionally dangerous because they can easily burn the people using them, they can start the vessels on fire if there is a fuel leak and they can even burn under water creating additional problems. Moreover, one cannot overemphasize the potential environmental disaster of flare disposal. Over the next three years it is estimated that approximately 30 million flares will be disposed of improperly or illegally. 
         [0003]    The Coast Guard&#39;s Research, Development, Test and Evaluation (RDT&amp;E) program is working on more than 80 projects that support Coast Guard requirements across all mission areas. The RDT&amp;E program is comprised of the Office of RDT&amp;E at Coast Guard Headquarters in Washington, D.C., and the Research and Development Center (RDC) at New London, Conn. The RDC is the Coast Guard&#39;s sole facility performing applied RDT&amp;E experimentation and demonstrations. 
         [0004]    The RDT&amp;E program pursues technologies that provide incremental improvements as well as those with the greatest potential to strategically transform the way the Coast Guard does business. 
         [0005]    The RDT&amp;E program leverages partnerships with academia, other government agencies and private industry, to proactively anticipate and research solutions to future technological challenges. 
         [0006]    Search and Rescue Distress Notification Methods and Alternatives by the United States Coast Guard reviewed pyrotechnic flares that are commonly used by mariners to signal distress. Flares have drawbacks and present significant storage and disposal problems. The RDC was sought to determine appropriate criteria to evaluate light emitting diode (LED) or other light signals as potential maritime distress signals. 
         [0007]    The project team selected a group of LED, flashtube (strobe) and incandescent-based devices to obtain photometric data. An understanding of the physical and perceptual aspects of these devices allowed the project team to select a subset of devices for further evaluation. 
         [0008]    Following the lab tests, the project team designed and conducted two field demonstrations. The first demonstration assessed individual devices to determine the most effective signal characteristics based on detectable range, ability to attract attention and ability to distinguish the signal against background lighting. A second demonstration used a subset of the devices to compare the most effective characteristics, head-to-head. Finally, a separate evaluation looked at device ergonomics to help understand the physical aspects of the devices that would make them easier to use. 
         [0009]    This project was to determine suitability of potential alternatives to pyrotechnic visual distress signals by: 
         [0010]    Evaluating the effectiveness of presently available LED (and other) devices as Visual Distress Signal Devices. 
         [0011]    Reviewing functional requirements for visual distress signals. 
         [0012]    Investigating and reporting on device characteristics and evaluating them against existing pyrotechnic standards. 
         [0013]    Investigating and reporting on “experimental” or “developmental” technologies and evaluating them against pyrotechnic standards. 
         [0014]    Determining the most effective light-signal characteristics for alternative Visual Distress Signal Devices. 
         [0015]    Additionally, this project will produce recommendations for future non-pyrotechnic requirements and applications. Recommendations will address the feasibility of whether non-pyrotechnic devices could replace pyrotechnics as alert, locate and/or marker devices. Alert and locate specifications for the signal lights differ in the varying peak intensity and the focal height of the LED emitted light, which can be altered by manually adjusting the distance between the LED and the optics. 
         [0016]    Numerous innovations for the Visual Distress Signal Device have been provided in the prior art that are described as follows. Even though these innovations may be suitable for the specific individual purposes to which they address, they differ from the present design as hereinafter contrasted. 
         [0017]    The following is a summary of those prior art patents most relevant to this application at hand, as well as a description outlining the difference between the features of the Visual Distress Signal Device and the prior art. 
         [0018]    U.S. Pat. No. 7,153,002 of Jin Jong Kim describes a lens for light emitting diode (LED) light sources which allows light emitted from an LED light source to exit the lens in a direction perpendicular to a vertical center axis of the lens. The lens of the present invention includes an inner space which is defined in a lens body having both a bottom surface and an upper reflective surface, so that light passing through the inner space is partially reflected by total internal reflection on a portion (selective transmission surface, inner reflective surface, inside reflective surface) of a boundary surface between the inner space and the lens body. Thus, light emitted from an LED light source efficiently exits the lens through a side surface. Accordingly, the lens of the present invention is used in efficient display and illumination of optical systems. 
         [0019]    This patent describes a light emitting diode (LED) light source which allows light emitted from an LED light source to exit the lens in a direction perpendicular to a vertical center axis of the lens used in display and illumination optical systems. This lens does not have the same internal structure and it only describes an LED light source exiting the lens in a direction perpendicular to a vertical center axis of the lens. It does not address the value of a portion of the light to be directed vertically or describe the other unique features of the Visual Distress Signal Device. 
         [0020]    U.S. Pat. No. 6,679,621 of Robert S. West et al. describes a lens that comprises a bottom surface, a reflecting surface, a first refracting surface obliquely angled with respect to a central axis of the lens, and a second refracting surface extending as a smooth curve from the bottom surface to the first refracting surface. Light entering the lens through the bottom surface and directly incident on the reflecting surface is reflected from the reflecting surface to the first refracting surface and refracted by the first refracting surface to exit the lens in a direction substantially perpendicular to the central axis of the lens. Light entering the lens through the bottom surface and directly incident on the second refracting surface is refracted by the second refracting surface to exit the lens in a direction substantially perpendicular to the central axis of the lens. The lens may be advantageously employed with LEDs, for example, to provide side-emitting light-emitting devices. A lens cap attachable to a lens is also provided. 
         [0021]    This patent describes a side-emitting light-emitting lens that does not have the same internal structure and again does not address the value of a portion of the light to be directed vertically or describe the other unique features of the Visual Distress Signal Device. 
         [0022]    U.S. Pat. No. 6,607,286 of Robert S. West et al. describes a lens mounted to a light emitting diode package internally redirects light within the lens so that a majority of light is emitted from the lens approximately perpendicular to a package axis of the light emitting diode package. In one embodiment, the light emitted by the light emitting diode package is refracted by a saw tooth portion of the lens and reflected by a total internal reflection portion of the lens. 
         [0023]    This patent describes another side-emitting light-emitting lens that does not have the same internal structure and again does not address the value of a portion of the light to be directed vertically or describe the other unique features of the Visual Distress Signal Device. 
         [0024]    U.S. Pat. No. 6,598,998 of Robert S. West et al. describes a lens mounted to a light emitting diode package internally redirects light within the lens so that a majority of light is emitted from the lens approximately perpendicular to a package axis of the light emitting diode package. In one embodiment, the light emitted by the light emitting diode package is refracted by a saw tooth portion of the lens and reflected by a total internal reflection portion of the lens. 
         [0025]    This patent describes another side-emitting light-emitting lens that does not have the same internal structure and again does not address the value of a portion of the light to be directed vertically or describe the other unique features of the Visual Distress Signal Device. 
         [0026]    U.S. Pat. No. 2,492,837 of Eugene Briggs describes an electronically operated signal lights and more particularly to a portable light of the flashing type adapted for emergency or signal use. 
         [0027]    This patent describes a self-contained portable flashing light of the gaseous discharge type energized by a battery that has not been designed to be used in a marine environment and does not float in the water. 
         [0028]    U.S. Pat. No. 5,034,847 of John E. Brain describes a portable light beacon for use on life rafts and the like that has a long life due to a flashing light allowing the battery to recharge and a water sensing switch that once wet remains on. The light beacon comprises a portable battery power source in a water proof container, a flashing light with watertight electrical connections between the flashing light and the power source, and a fluid sensing switch comprising a fluid absorbent composition positioned between two terminals with circuitry to activate the flashing light when an electrical conductive fluid has been absorbed by the fluid absorbent composition to provide an electrical path between the two terminals. 
         [0029]    This patent describes a hand held light beacon for use on life rafts and the like that has a long life due to a flashing light but does not have the lens capability of horizontal or vertical light directing and has not been designed to float vertically or be tied by a lanyard lifted to the top of a mast. 
         [0030]    U.S. Pat. No. 7,182,479 of John f. Flood et al. describes a portable, hand-held, electrically powered, high intensity directed light beam generating device for use as a replacement for a pyrotechnic flare for search and rescue, especially in a marine environment. The light intensity is generated by a xenon strobe flash tube in a covered, mirror reflective housing that allows for a directional beam of light of less than 6 steradians. The limited radiation light direction provides a safe optical solution for the user to prevent eye damage while increasing the beam intensity and range. The light and illumination section surrounding the strobe flash tube includes thermally conductive paths for the heat generated by the flash tube to be transmitted to the outside of the housing. 
         [0031]    This patent describes a hand held electrically powered, high intensity directed light beam generating device but does not have the unique lens capability nor does it float in the water and if you let go of it would sink. 
         [0032]    U.S. Pat. No. 7,703,950 of Jurgen E. Ewert et al. describes a side-emitting lens for use with an LED lamp provides a distribution of emitted light that is substantially normal to an axis of symmetry of the lens; the light can also be symmetrical with respect to a plane normal to the lens axis. The lens has a cavity in which the LED lamp can reside, having a cavity refracting surface with a central section and a stepped cavity sidewall. The lens also has a base external refracting surface surrounding the cavity, an internal reflecting surface spaced apart from the cavity, and a side surface; these surfaces redirect light that enters the lens through the cavity refracting surface. For many applications, the lens axis is vertical in service and the lens is configured to provide a narrow distribution of light in the horizontal plane. 
         [0033]    This patent describes only a side-emitting lens for an LED lamp having a base section with a cavity defined by a cavity refracting surface with a substantially planar central section, which is substantially normal to the central lens axis, and a stepped cavity sidewall having a series of sidewall refracting surfaces, and a base external refracting surface symmetrically disposed about the central lens axis and spaced apart from said stepped cavity sidewall. The Visual Distress Signal Device lens does not have the stepped cavity sidewall but has a concave inner surface while having drain capability of the conical upper cavity. The application additionally provides the complete structure of the Visual Distress Signal Device and its unique floating capabilities. 
         [0034]    U.S. Pat. No. 8,702,256 of Hans Poul Alkaer relates to an emergency light device for marine use comprising a housing accommodating an electronic circuit, at least one transparent dome, and a first and a second housing member, said electronic circuit comprising at least one light emitting diode provided in the one transparent dome, an electrical power supply comprising at least one battery of the AA, AAA or AAAA type, and at least one operating switch, said emergency light characterized in that the housing has a width which is substantially larger than the height, preferably the width is at least double or triple the height. 
         [0035]    This patent describes a light for a life jacket that would sink if it were dropped in the water and does not provides the complete structure of the Visual Distress Signal Device and its unique floating capabilities. 
         [0036]    U.S. Pat. No. 6,805,467 of Edward A. Wolf describes a portable emergency light for long range detection by flight and marine search and rescue personnel which utilizes a battery-powered laser array mounted and sealed within a waterproof housing to increase the effective intensity of a specific class laser. The laser array includes a plurality of laser light generators mounted together to project substantially along a common optical axis producing a signaling light. The search and rescue light may include a rotatable head for directing the signaling lights along a 360 degree plane and a three-dimensional gimbal which maintains the light beams in a level horizontal position so that the signaling lights may be easily projected along the entire horizon relative to the user. Each laser light generator is within US Government safety standards for the specific class laser despite the increased power of the signal. The laser array can be used with optical alignment lenses to form a desired highly visible light pattern. 
         [0037]    This patent describes an emergency laser array signal light that utilizes a battery-powered laser array mounted and sealed within a waterproof housing to increase the effective intensity of a specific class laser but does not have any floating capability. 
         [0038]    In this respect, before explaining at least one embodiment of the Visual Distress Signal Device in detail it is to be understood that the design is not limited in its application to the details of construction and to the arrangement, of the components set forth in the following description or illustrated in the drawings. The Visual Distress Signal Device is capable of other embodiments and of being practiced and carried out in various ways. In addition, it is to be understood that the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting. 
       SUMMARY OF THE INVENTION 
       [0039]    The principle advantage of the Visual Distress Signal Device is to be used to locate marine vessels and or persons in distress, with a high-intensity portable LED signaling light that is compliant within current and future published governmental regulations for devices utilized in search and rescue operations. 
         [0040]    Another advantage of this Visual Distress Signal Device to provide a LED signaling device that eliminates the use of pyrotechnic flares especially in marine environment. 
         [0041]    Another advantage of this Visual Distress Signal Device is that the primary light source is not only directed in a horizontal plane, for radial symmetry, but a portion is directed vertically through a transitional angle of divergence between horizontal and vertical planes. 
         [0042]    Another advantage of the Visual Distress Signal Device is that it has one or more intermittent LED lights that can be provided in varying colors and can replicate one or more preprogrammed approved distress signal flash sequences such as an SOS signal or other defined flash patterns. 
         [0043]    Another advantage of the Visual Distress Signal Device is changes to the vertical position of the LED changes the aiming direction of the beam from both the first and second parts of the lens. This allows the peak intensity of the lens to be varied as needed for specific applications. Raising the position of the LED within the lens will lower the beam angle from the first section of the lens and raise the beam angle from the second total internal reflection (TIR) section of the lens. So this allows the total beam angle to be widened or split into 2 beams if desired. This is particularly helpful in switching from the alert to the locate signal status during a search and rescue operation. 
         [0044]    Another advantage of this Visual Distress Signal Device to provide a LED signaling device that eliminates the problems of storage and disposal of old or damaged pyrotechnic flares. 
         [0045]    Another advantage of the Visual Distress Signal Device is to provide a very high-intensity portable light signaling device that is safe for the user in any environment. 
         [0046]    Another advantage of the Visual Distress Signal Device is that it will float in an upright position. 
         [0047]    Another advantage of the Visual Distress Signal Device is that in a lower compartment it can house either a die marker, a Coast Guard approved distress flag or a non-pyrotechnic smoke generating device. 
         [0048]    Another advantage of the Visual Distress Signal Device is that the conical central element of the lens has a means to drain water that collects in the center. 
         [0049]    Yet another advantage of the Visual Distress Signal Device is being portable, floatable and can be hoisted aloft for optimal visual range and effectiveness and also be tethered to the vessel, a life raft or person in the water. Additionally, with the flag or dye marker removed from the chamber housing same, a pole or boat hook can be inserted into the empty chamber to elevate the device. In this regard, the lower chamber is sized for display in a standard cup holders or fishing rod holders commonly found on most boats. 
         [0050]    The Visual Distress Signal Device provides a high-intensity, radially symmetrical, omni directional beam electrically-powered, LED light generating signal locating device for use as a replacement of pyrotechnic flares. 
         [0051]    The Visual Distress Signal Device has a lens with a conical upper reflective cavity with the capability to drain any moisture out to the side by the means of one or more vertical slits or one or more slanting drain holes at the bottom of the conical cavity. The device also incorporates a snap on lower section to house either a die marker, or an internationally recognized distress signaling flag used to aid search and rescue personnel or a non-pyrotechnic smoke generating device. The LED&#39;s timing and control of the pulsating flashes is electronically controlled by electrical circuitry that will use a programmable microcontroller. 
         [0052]    The marine application includes a waterproof housing with sealing O-rings employing an exterior magnet on the optical lens cap which will be rotated for activation of the LED light reed switch without compromising the housing structure. 
         [0053]    The light intensity distribution generated by the Visual Distress Signal Device is greater than 75 candelas in the horizontal plane and greater than 15 candelas along the vertical axis. The light is generated by one or more pulsating light emitting diodes (LEDs) and is distributed by three distinct sections of an optical lens. Light entering the first section of the lens is refracted through the outer lens surface into the horizontal plane. Light entering the second section of the lens is refracted toward a total internal reflection (TIR) feature, which then reflects light toward the horizontal plane. Light entering the third section of the lens, directly above the LED, is allowed to pass through the inner and outer surfaces relatively unaffected, thus maintaining its original direction toward the vertical axis. The unit is powered by one or more batteries, preferably lithium or alkaline batteries. 
         [0054]    A feature of the Visual Distress Signal Device is that changes to the vertical position of the LED changes the aiming direction of the beam from both the first and second parts of the lens. This allows the peak intensity of the lens to be varied as needed for specific applications. Raising the position of the LED within the lens will lower the beam angle from the first section of the lens and raise the beam angle from the second total internal reflection (TIR) section of the lens. So this allows the total beam angle to be widened or split into 2 beams if desired. 
         [0055]    The operational instructions for the Visual Distress Signal Device are:
       Snap the lower compartment to the upper housing.   Insert batteries in battery holder board assembly.   Place supplied EDPM O-ring seals in grooves below thread group on upper housing.   Insert complete battery holder board assembly in opening of upper assembly. Lower into place, rotate to align board for proper switch operation position.   Thread optical lens cap on upper housing clockwise until it bottoms out. Magnet will line up with the word “ON” and the device will be operating. Rotate lens cap counterclockwise to the word “OFF” Your device is now at the ready. A third setting for “TEST” is also anticipated, as well as a battery strength signal switch, for when the light is tested and the batteries checked with turning on the light.       
 
         [0061]    When the magnetically activated reed switch is first turned on to power the circuit pass element, in this example the MOSFET Q 1  is turned on. The current through the LED and inductor ramps up until the current through the current sensor element matches the reference. Then pass element, in this example a MOSFET Q 1  is turned off and an inductor L 1  continues to supply the current through zener D 3  until its stored energy is exhausted. After some delay, the MOSFET Q 1  is turned on again and the cycle repeats. This cycle repeats during the time the light source is intended to be on and effectively generates the maximum light with the most efficient use of the battery power. Various patterns can be constructed by turning this cycle on and off. For example an S-O-S pattern for a marine beacon. Other color combinations are anticipated, such as cyan-cyan-cyan, red/orange-red/orange-red/orange and numerous other combinations of these colors, chosen from all wavelengths of the visible light spectrum, with white LED emitted light mixed in. 
         [0062]    The foregoing has outlined rather broadly the more pertinent and important features of the present Visual Distress Signal Device in order that the detailed description of the application that follows may be better understood so that the present contribution to the art may be more fully appreciated. Additional features of the design will be described hereinafter which form the subject of the claims of this disclosure. It should be appreciated by those skilled in the art that the conception and the disclosed specific embodiment may be readily utilized as a basis for modifying or designing other structures and methods for carrying out the same purposes of the present design. It should also be realized by those skilled in the art that such equivalent constructions and methods do not depart from the spirit and scope of this application as set forth in the appended claims.

       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0105]    Referring now to the drawings, wherein similar parts of the Visual Distress Signal Device  10 A and  10 B are identified by like reference numerals, there is seen in  FIG. 1  a perspective of the Visual Distress Signal Device  10 A with the protective lens cover  12  and a bottom cap  14  with drain orifices  15 . This view illustrates the transparent lens  16  with the magnet protrusion  18  and the on and off positioning indicators  22  and  24  on the bulbous top portion  26  of the water tight light housing  28  above the cylindrical grip portion  30  with nonslip ribs  32 . The removable snap-on lower compartment  34  has orifices  41  on the top surface to allow air to escape or water to get in to maintain the vertical positioning of the device. The Visual Distress Signal Device is specifically configured and designed to float with the same characteristics with or without the lower chamber attached. Thus, the lower chamber is optional. 
         [0106]      FIG. 2  depicts a perspective of the Visual Distress Signal Device  10 A illustrating the location of the upper lanyard attachment orifice  42  attached to the bulbous top portion  26 , the cylindrical grip portion  30  having nonslip ribs  32  and the snap on storage compartment  34  with the distress flag lanyard orifice  43  on the lower edge. 
         [0107]      FIG. 3  depicts a top view of the Visual Distress Signal Device  10 A illustrating the conical upper surface  46  of the transparent lens  16  with the magnet protrusion  18 . The ON and OFF positioning indicators  22  and  24  are on the bulbous top portion  26  of the water tight light housing  28 . 
         [0108]      FIG. 4  depicts a cross section of the Visual Distress Signal Device  10 A illustrating the transparent lens  16 , with the two O-ring seals  47 , and the location of the battery tray/circuit board perch assembly  48  within the water tight light housing  28 . The bottom of the battery tray/circuit board perch assembly  48  is incased with a soft cushioning material  29  within the cylindrical grip portion  30 . The water line  45  is shown along the bulbous top portion  26  of the water tight light housing  28 . The battery tray/circuit board perch assembly  48  is shown with the battery compartment  49  and the extended perch legs  50  with the electronic reed switch  51  attached. The extended perch legs  50  are connected to the circuit board mounting plate  52 . The snap-on storage compartment  34  shown with a flag lanyard orifice  43 , can house a Coast Guard approved distress flag  36 , a dye marker pack  38  or a non-pyrotechnic smoke generating device  40 . 
         [0109]      FIG. 5  a perspective view of the battery tray/circuit board perch assembly  48  illustrating the battery compartment  49  and the extended perch legs  50  with the electronic reed switch  51  attached is shown connected to the circuit board mounting plate  52 . The circuit board mounting plate  52  has on the upper surface two banana plugs  54 , two alignment pins  56  and two snap-on couplings  58 . 
         [0110]      FIG. 6  depicts a cross section through the upper section of the transparent lens  16  defining the drain slots  66  and the general positioning of the ray patterns  60 ,  62  and  64  vertically and three hundred and sixty degrees through the transparent lens  16  from the LED light  65 . The inner lens surface  68  directs light onto the upper internal reflection surface  70  of the conical segment  72 , forming the light in a ray pattern  60  toward the horizon. The rays are not all perfectly parallel due to the faceted outer surface to add a bit of spread to the beam to help improve the tolerance due to manufacturing variations. The ray pattern  62  is directed through the inner concave surface  74  and in a horizontal direction through the outer convex surface  76  of the transparent lens  16  while the ray pattern  64  is directed at approximately fifteen degrees through the two flat surfaces  78  and  80  in the transparent lens  16  in a vertical direction. This image is from a real ray trace of a polar array of collimated beams put through the transparent lens  16 . 
         [0111]      FIG. 7  depicts a cross section through the upper section of the transparent lens  16  defining the light ray patterns  60 ,  62  and  64  and reflection surface  70  of the conical segment  72 . The alternate embodiment of the transparent lens  16  will have a plurality of drain holes  84  slanting to the lower circumference of the conical segment  72  to drain water from the conical segment  72 . 
         [0112]      FIG. 8  depicts a side view of the circuit board  88  with a single LED light  65 . 
         [0113]      FIG. 9  depicts a top view of the circuit board  88  with a single LED light  65  with the large alignment tab  90  and the small alignment tab  92 . Four holes in the circuit board  88  align to secure the circuit board  88  to the circuit board mounting plate. Electrical connectivity is made from the battery pack to the circuit board with two banana pins. Alignment tabs  90  and  92  on the board  88  allow the board  88  to be indexed to the upper watertight housing  28 . 
         [0114]      FIG. 10  depicts a top view of the circuit board  88  with a three LED&#39;s lights  65  and the large alignment tab  90  and the small alignment tab  92 . 
         [0115]      FIG. 11  depicts an exploded perspective view of the Visual Distress Signal Device  10 A illustrating the large alignment slot  94  and small alignment slot  96  for the positioning of the battery tray/circuit board perch assembly  48  (shown in  FIG. 4 ). The slots are in the outer rim  98  of the water tight light housing  28  for the mating of the large alignment tab  90  and the small alignment tab  92  on the circuit board  88  in relation to the electronic reed switch  51  (shown in  FIG. 4 ). 
         [0116]      FIG. 12  depicts a schematic for Visual Distress Signal Device  10 A with a single LED (D 4 ), that details that the circuit is controlled by a microcontroller or processor (U 1 ) that is controlled by software. The circuit is energized by a power source supplied to Bat+ and Bat−. The circuit has inputs TP 1  through TP 4  that enable “In circuit programming”. The power source is controlled by reed switch (S 1 ). R 1  acts to limit the inrush current going to the storage capacitor (C 2 ). Reverse power source protection is provided by (D 1 ). Since the power source can be variable, the zener (D 2 ) regulates the voltage supplying power to the microcontroller (U 1 ). Frequency control is provided by a crystal (X 1 ) in this example, but can be provided by any frequency regulating device. The output of the microprocessor controls a pass element, in this example a MOSFET (Q 1 ), which is driven by a MOSFET Driver (U 2 ). This pass element allows current to flow through a light emitting source, in this example an LED (D 4 ), an inductor (L 1 ), and a current sense element, in this example, a resistor (R 5 ). When Q 1  is turned on, the current builds up a magnetic field in the inductor (L 1 ) storing energy. When Q 1  is turned off, inductor (L 1 ) supplies current through D 3 , continuing to power the LED (D 4 ), until the field in inductor (L 1 ) collapses. 
         [0117]    The microcontroller senses the current, in this example by using an internal comparator (ACMP+ and ACMP−) to compare the voltage across R 5  that represents the current, to a voltage supplied by a reference, in this example a voltage provided by a voltage divider R 3  and R 4 . This controls the peak current. Points “A” and “B” are for wiring an alternate electronic switch to the reed switch shown and described above (see  FIG. 19 ). 
         [0118]      FIG. 13  depicts a schematic for Visual Distress Signal Device  10 B with similar characteristics except having the option of having multiple LED lights  65 . 
         [0119]    Referring now to  FIG. 14 , there is shown a similar schematic for Visual Distress Signal Device  10 C with multiple LED&#39;s and an embedded beacon transmitter. A circuit controlled by a microcontroller or processor (U 1 ) that is controlled by software. The circuit is energized by a power source supplied to Bat+ and Bat−. The circuit has inputs TP 1  through TP 4  that enable “In circuit programming”. The power source is controlled by a switch. In this example, this is a reed switch (S 1 ). R 1  acts to limit the inrush current going to the storage capacitor (C 2 ). Reverse power source protection is provided by (D 1 ). Since the power source can be variable, the zener (D 2 ) regulates the voltage supplying power to the microcontroller (U 1 ). Frequency control is provided by a crystal (X 1 ) in this example, but can be provided by any frequency regulating device. The output of the microprocessor controls a pass element, in this example a MOSFET (Q 1 ), which is driven by a MOSFET Driver (U 2 ). This pass element allows current to flow through a light emitting source, in this example an LED (D 4 ), an inductor (L 1 ), and a current sense element, in this example, a resistor (R 5 ). 
         [0120]    The light source can be a single element like an LED or multiple elements represented by “Dn” and placed in series illustrated by the dotted line trace. When Q 1  is turned on, the current builds up a magnetic field in the inductor (L 1 ) storing energy. When Q 1  is turned off, L 1  supplies current through D 3 , continuing to power the LED until the field in L 1  collapses. The microcontroller senses the current, in this example by using an internal comparator (ACMP+ and ACMP−) to compare the voltage across R 5  that represents the current, to a voltage supplied by a reference, in this example a voltage provided by a voltage divider R 3  and R 4 . This controls the peak current. 
         [0121]    Another embodiment would have multiple additional drivers and light sources, represented by the example additional circuit in the dotted box within for Visual Distress Signal Device  10 C as shown in  FIG. 14 . This allows lighting separate light sources in different patterns and at different times. 
         [0122]    The Algorithm for Visual Distress Signal Device  10 C would function as follows: the switch is first turned on to power the circuit. Then Q 1  is turned on. The current through the LED and inductor ramps up until the current through the current sense element matches the reference. Then Q 1  is turned off and L 1  continues to supply the current through D 3  until its stored energy is exhausted. After some delay Q 1  is turned on again and the cycle repeats. This cycle repeats during the time the light source is intended to be on. Various light patterns, random and defined, can be constructed by turning this cycle on and off. For example an S O S pattern for a marine beacon. 
         [0123]    An additional embodiment would provide additional drivers allowing multiple circuits to use this algorithm independently. 
         [0124]      FIG. 15  depicts a communications flow diagram  100  of an additional controller in communication with a WiFi module and a radio module, with a light source controller present. An additional controller  102  is in communication with a WiFi module  104 , and a radio module  106 . A light source controller  108  is also present. 
         [0125]      FIG. 16  depicts a communications flow diagram  110  of an additional controller in communication with a WiFi module and a radio module. An additional controller  112  is in communication with a WiFi module  114 , and a radio module  116 . 
         [0126]    The alert system functions as follows: either an additional micro-controller or an enhanced version of the micro-controller that blinks the light source can be used to interface with an alert system. It can be interfaced with a WiFi Module such as a Freescale TWR-WIFI-AR4100 or a Radio Module such as a Maxim SKY77555 or a conventional transmitter circuit to transmit the information. The WiFi module could be setup as a WiFi hotspot with a web-page displaying an alert. Anyone in range looking for this hotspot would see the alert for example in a cellphone application. It could display the name of the vessel and the location for example. See  FIGS. 15 and 16 . 
         [0127]    Another embodiment would allow the application to contact a server which monitors the GPS coordinates of its users. Users within an appropriate distance, or land based contacts which are user defined, would be notified by an alert in the form of a text, email, or any combination of these. See  FIGS. 15 and 16 . The alert can also be in the form of a phone call or an alert message sent to a server through the mobile application. The server can also send alerts to the Coast Guard or equivalent agency, a towing or vessel assist service, search and rescue (SAR) personnel, emergency medical systems (EMS) personnel, the cloud, the Rescue Coordination Center, and/or other land-based resources as necessary. 
         [0128]    A third embodiment would use a radio module to send out the alert or contact the Coast Guard. See  FIGS. 15 and 16 . 
         [0129]    Any combination of these could be used together. See  FIGS. 15 and 16 . 
         [0130]      FIG. 17  depicts a communication system  120  wherein a GPS device can interface with the Internet using a cell phone transmitter adaptor with mobile application software  122  to provide a connected Visual Distress Signal Device unit  126  on board a vessel  124 . The cell phone transmitter adaptor with mobile application software  122  connected Visual Distress Signal Device unit  126  includes a PCB having an integrated electronic beacon with capability for GPS, cell phone, WiFi and Internet connectivity through a common server  130  in communication with cell phone towers  128  and  132 . 
         [0131]    For enabling an Internet link, a unit with a GPS can interface with the Internet using a cell phone adaptor such as the ones available from most cell phone companies to connect to a laptop (see  FIG. 17 ). The information describing the location and vessel identification and nature of the distress can be sent to a server on the Internet. The server can compare the location of the vessel in distress with the database of locations of other vessels in the area. This database can be derived from the cell phones of users of the software application in the area. This software application would periodically transmit the location and nature of distress or other predefined message content from of the user&#39;s phone. The server would alert the vessels in the area or land based contacts (user defined i.e. contact list in phone or assistance resources, for example commercial towing, vessel assist or Coast Guard by sending a text an alert in the software mobile application on the phone, a text message, a phone call, an email, or some combination of these alert forms. 
         [0132]      FIG. 18  depicts a communication system  140  wherein a GPS device can interface with the Internet using a radio transmitter  144  to provide a connected Visual Distress Signal Device unit  146  on board a vessel  124 . The radio transmitter  144  connected to the Visual Distress Signal Device unit  146  on board a vessel  124 , includes a PCB having an integrated electronic beacon with capability for GPS, cell phone, WiFi and Internet connectivity through a common server  130  in communication with radio tower  142  and cell phone tower  132 . 
         [0133]    For enabling a radio link, a unit with a GPS can interface with the Internet using a radio transmitter (see  FIG. 18 ). The information describing the location and vessel identification can be sent to a server on the Internet. The server can compare the location of the vessel in distress with the database of locations of other vessels in the area. This database can be derived from the cell phones of users of the software application in the area. This software application would periodically transmit the location and nature of distress or other predefined message content from of the user&#39;s phone. The server would alert the vessels in the area or land based contacts (user defined i.e. contact list in phone or assistance resources, for example commercial towing, vessel assist or Coast Guard by sending a text an alert in the software mobile application on the phone, a text message, a phone call, an email, or some combination of these alert forms. 
         [0134]    Another embodiment of the alert system anticipates a cellphone application. This application would present a web page to enter the vessel&#39;s information. The GPS present in the cellphone would pass the location information to the application. Periodically, this information would be sent by the cellphone via the internet to a central server. This would allow a program on the server to know the location of all of the cellphones using the application. A person on the vessel could activate the alert function of the application. The cellphone would send the alert to the server which would compare the location of the cellphone that issued the alert and the location of the other cell phones in the area. The server would relay the alert the alert to all of the cellphones using the application within a given radius of the cellphone that issued the alert. 
         [0135]    Referring now to  FIG. 19  there is illustrated an electronic version of the reed switch in the form of a SM353LT electronic switch which is activated by a magnetic field. This electronic version of the reed switch is wired to the schematic shown in  FIG. 12  by way of the “A” point to the circuit ground, and the “B” to the circuit (see the “A” and the “B” points clearly shown in  FIG. 12 ). The SM353LT is an off the shelf available electronic switch activated by a magnetic field. In an alternate embodiment, using the SM353LT, the magnet that would control the reed switch would instead control the SM353LT. D 5  is a zener diode and regulates the voltage across U 3 . R 6  limits the current to U 3  and to the zener. U 3  turns on when subjected to a magnetic field. This turns on Q 2  through R 7 , a current limiting resistor. The rest of the circuit works as in the previous version. Alternatively, a mechanical switch for activation of the circuit in an on/off or test mode could be utilized. 
         [0136]      FIG. 20  depicts a lens configuration having an array of LED&#39;s mounted on a centrally located post, illustrating the light distribution. The lens assembly  200  is comprised of a lens body  202  having a central cavity  204 . The inner surfaces are comprised of an upper portion  206  having a bell shaped inner chamber  208 , and a lower conical inner surface  210 . A centrally located beacon heatsink post  212  has an array of LED&#39;s  214  mounted thereon, such that light diffraction rays  216  and  218  are generated. 
         [0137]      FIG. 21  depicts a lens configuration having a flashtube mounted on a centrally located post, illustrating the light distribution. Similar to the lens configuration in  FIG. 20 , the lens assembly  220  in  FIG. 21  is comprised of a lens body  222  having a central cavity  224 . The inner surfaces are comprised of an upper portion  226  having a bell shaped inner chamber, and a lower conical inner surface  230 . A centrally located beacon heatsink post  232  has a flashtube  234  mounted thereon, such that light diffraction rays  236  and  238  are generated. Another light source could be a flash tube. The importance of another light source being a flash tube, or one or more flashtubes, is that it can be very bright. A flash tube such as shown in  FIG. 21  is driven by a high voltage supply and is triggered by an electrode on the side of the glass. The two electrodes at each ends of the flash tube  234  are presented with a high voltage that is just short of arcing through the tube. The electrical discharge through the flash tube is triggered by presenting the center electrode with a high voltage. Moreover, this flash tube  234  could be coated with a conversion phosphor; one that takes the smaller wavelength light and converts it to higher wavelength light, changing the color distribution of the light. Another embodiment would use a filter that would be placed over the flash tube to select certain colors and/or wavelengths within the fill range of visible and invisible light, such as infrared (IR) and ultraviolet (UV). These circular flash tubes would be supported by clips that are attached to a central post placed in the center of the lens assembly  220 . The novelty of this approach is that the light from the flash tubes can be evenly distributed around the ring as opposed to the light distribution from individual sources such as LEDs. 
         [0138]    The lens body  202  is composed of two sections: the bottom section is angled toward the horizon and angled up 15 degrees. The top section is aimed 15 degrees to straight up. It is intended to be used to configure the distribution of light from a ring of LED&#39;s placed in a radial direction. The lenses  202  and  222  have the novelty of being able to distribute more light in the horizontal direction gradually dimming as the angular elevation increases (see the light distribution graph in  FIG. 22 ). This lens configuration also cuts back on the light going below the horizon. The radii and dimensions can be varied to accommodate the number and type of light source required, whether it is in the form of an array of LED&#39;s or a flashtube, or the like. 
         [0139]    Thus, the novelty of the lens shape (bell shaped inner chamber) is in the fact it directs the light from a ring or array of LEDs or other light source such as a flash tube preferably but not limited to in a radial pattern with the intensity concentrated from the horizontal plane to some angle; 30 degrees for an example. This is important because the power required for a beacon is proportional to the total light (see  FIG. 22  below). 
         [0140]      FIG. 22  depicts a chart graphically illustrating the light distribution by candela and vertical degrees of angle. It shows the distribution of light from the beacon lens in relative intensity (candela) and vertical angle in degrees for the entire 0 degrees straight down to 180 degrees straight up. 
         [0141]      FIG. 23A  depicts a beacon housing including a mechanical power recharge mechanism that works by wave motion. Within the beacon there can be located this wave motion power supplying mechanism  250  for generating power to be stored or to charge a battery. The beacon housing  252  has a centrally located generator  254  and a swing support arm  256  including a roller weight  258  and spacer  260 . During wave action, the sing support arm  256  moves along the indicated arrow within the beacon housing  252 , and with the aid of the roller weight  258 , that swinging rolling motion is transmitted to the generator  254  to generate power directly from wave motion. 
         [0142]      FIG. 23B  depicts an induction charging system  280  where a beacon housing  282  having a beacon unit coil  284  coupled to a printed circuit board (PCB)  286  in contact with an energy storage device  288 , here a battery, through a spring  290 , can be placed in a base  292  to be charged inductively. The base  292  includes a base coil  294  wired to a printed wiring assembly  296  which is connected to a power generation source  298 . The power generation source could be AC, DC, solar or mechanical. In this way, the charging elements for the energy storage elements can be inductively coupled to the energy storage devices. The base  292  would contain a printed wiring assembly  296  which would interface with the charging element; solar cells, AC voltage from the mains, etc. This assembly would contain an oscillator circuit which would drive a base coil  294 . The bottom of the beacon housing  282  could be inserted in the coil in the base. The device would also contain a beacon unit coil  284  which would be inductively coupled to the coil  294  in the base. This beacon unit coil  284  would be connected to a printed (PCB) wiring assembly  286  that would rectify the induced current, and regulate the voltage charging the energy storage device  288  housed within the beacon unit  282 . This would allow the beacon unit to be charged without having to physically connect the device to the base. 
         [0143]      FIG. 24  depicts a circuit schematic of solar cells used to power and recharge the energy storage elements, here a battery, within the beacon. Therefore, the beacon&#39;s energy storage element can be recharged in a number of ways: (1) since the waves in the ocean rock floating objects, a mechanism using this principle can be used to charge the energy storage element (see  FIG. 23  above). A regulator circuit such as shown in  FIGS. 24 and 25 , where this mechanism replaces the solar cell, can be used to prevent overcharging; and (2) solar cells can also be used to charge energy storage elements as shown in  FIGS. 24 and 25 . In  FIG. 24 , the solar cells can charge the battery, with the regulator limiting the voltage to prevent overcharging the battery. Another embodiment charges another energy storage element; a group of capacitors. Again, the solar cells can charge the capacitor array, with the regulator limiting the voltage to prevent overcharging the array. 
         [0144]      FIG. 25  depicts a circuit schematic of solar cells used to power and recharge the energy storage elements, here a capacitor array, within the beacon. The energy equivalent of capacitors is (½C (V 1 ×V 1 ))−(½C(V 2 ×V 2 )) where C is the total capacitance, V 1  is the higher (charged) voltage and V 2  is the lower (discharged) voltage. Capacitors have the advantage over batteries in that they can often be recharged hundreds of thousands of times. They can be recharged very quickly. 
         [0000]    Different regulators can be used to limit the voltage and/or current charging the energy storage element. A switching regulator or a linear regulator can be used.
 
The regulating circuit prevents overcharging the storage element. The voltage from the regulator is determined by the following formula:

         [0145]      FIG. 26  depicts a circuit schematic in which the beacon is powered by a battery, capacitor array or fuel cell. 
         [0146]    Energy storage devices such as these batteries and capacitive arrays, in addition to fuel cells (such as Brunton Hydrogen Reactor Portable Power Pack F-REACTOR-YL) could power a distress beacon. An example of such a circuit is shown in  FIG. 26  where U 1  would be a microcontroller and U 2  would be an LED switching regulator. Another circuit without a microcontroller is shown in  FIG. 27  below. 
         [0147]      FIG. 27  depicts another circuit schematic in which the beacon is powered by a battery, capacitor array or fuel cell, here illustrated without a microcontroller element present. 
         [0148]      FIG. 28  depicts a circuit schematic of a beacon including a wireless module, a microcontroller and an LED regulator. This beacon can include light sources of different colors and individual controlled flash patterns. It can include light sources such as flash tubes, LEDs or other infrared emitters within either the horizontal or vertical directions within the near IR wavelength and or far IR wavelength; from 700 nm to 1 mm wavelength. This will offer added detection of the Distress Light. Manned aircraft utilizing military or commercial grade Monocular Night Vision Devices (MNVD) with supplemental IR illumination greatly increases the distance at which the distress light can be located. Also, /drones/surface craft or satellites with IR detection systems will be effective. 
         [0149]      FIG. 29  depicts a circuit schematic of a beacon including a Bluetooth module in place of, or in addition to, a wireless module, a microcontroller and an LED regulator.  FIG. 28  shows an embodiment of the beacon that includes a wireless module (U 1 ), a microcontroller (U 2 ) and an LED regulator (U 3 ). This can be used with the Come Quick Distress Application mobile smartphone application as described in  FIGS. 30 through 39  below. Another embodiment uses a Bluetooth module as shown in  FIG. 29  that can be used in place of, or in addition to, the wireless module. 
         [0150]      FIG. 30  depicts a chart of how the beacon communicates to a smartphone and thereby to land based resources and other nearby cell phones. The distress beacon housing  310  supports the light signal  312 , but is also capable of communicating with a cell phone or smartphone  302  in an emergency situation. The cell phone  302  then sends a call or other information to cell tower  320  which passes that information on to the servers  330  and  332  which represent land based resources. These land based resources servers could then pass the information on to other cell phones  340  and  342 . Or, the cell tower may send information directly to other cell phones of nearby users  350 ,  352  and  354  in the vicinity. The Come Quick application allows someone in distress to send an alert to others requesting assistance. Using a wireless connection, the application on the cell phone sends the GPS location to a land based server via a cell phone network and the internet. This server keeps track of the position of all of the users. When a user is in distress, they send an alert to the server which in turn sends the alert to other vessels in the area. It can also call a tow service, the Coast Guard or other resources specified by the user (see  FIG. 30 ). The user fills out a plan for their voyage, the names and medical information for those passengers on board, the name and type of vessel, along with any other pertinent information such as the GPS locations of the intended positions and waypoints on the voyage. 
         [0151]      FIG. 31  depicts a “message in a bottle” function where information is downloaded to an active RFID card or other memory device on the beacon. This information can be downloaded to an active RFID card or on board memory on the beacon to provide a “Message in a Bottle” option. If the beacon were separated from the user, this information could be retrieved and would tell where the beacon came from. The alert message sent from the application to the network would contain the “Message in a Bottle” information. It would also contain the reason for the emergency. In this regard, the RFID card is connected to the microcontroller on the beacon, and sends information through a WiFi connection directly to the cell phone or smartphone  302 . 
         [0152]      FIG. 32  depicts a chart illustrating how an Ethernet circuit can be employed to remotely control the LED driver on the beacon. An antenna picks up an Ethernet connection, sends control data through an electronic switch to a microcontroller which then activates the LED driver which controls the LED (on/off, flashing, colors, etc.). One such embodiment includes a smaller personal distress signal version ideal for travel aboard aircraft which might if transiting overwater separate from possible wreckage if plane was downed. Distress signal device would separate from wreckage at impact and float to surface aiding in locating survivors and debris. There would also be an option to send a signal to a wireless or Bluetooth module on the beacon. This provides a means of downloading the “message in a bottle” information to the beacon. This could also be used to remotely start the beacon. Also, a wireless rocker switch such as Cherry Switch&#39;s AFIS series can be used to activate the beacon or send a distress signal if the phone and/or the beacon were away from the user in an emergency. These switches require no batteries and harness the energy of the switch&#39;s motion. They could be placed in a key fob on a keychain and used without worry that the battery went dead. 
         [0153]      FIG. 33  depicts a miniaturized version of the beacon having water activation switch and an impact inertia switch. This smaller beacon  380  is comprised of a floating housing  382  having an internal battery  384  or other power source supported by a battery spring  386 , to power a light source  388 . The light is directed outward through the lens  390  which when the smaller beacon unit  380  is floating in water, said lens  390  sticks up out of the water above the water line as shown here in  FIG. 33 . The smaller beacon unit  380  is also equipped with both a water activation switch  392  being activated when water pours though opening  394 , and an impact inertia switch  396 , as well as a conventional mechanical manual on/off switch  398 . This embodiment including a smaller personal distress signal  380  is ideal for travelers aboard aircraft which might if transiting overwater separate from possible wreckage if plane made a water landing or was downed. The distress signal device  380  would separate from the wreckage at impact and float to surface aiding in locating survivors and debris. The beacon light would turn on in the event of water activation or impact activation, or could be manually switched on, in any emergency situation. 
         [0154]      FIG. 34  depicts a detailed chart illustrating the message path taken by the beacon to alert distress to land based resources and nearby vessels with Internet connectivity. The basic function of the Come Quick Distress mobile application is to provide a means of requesting assistance in an emergency. Since most people have a cell phone, and in most cases a smartphone today, this application works on cell phones and smartphones. 
         [0155]      FIG. 35  depicts several screen shots of a mobile application for communication between the beacon and smartphones having a home level and two first levels, a second level and a third level. There are two different home screens; one for motor vessels and one for sailing vessels. There are menus for providing the vessel profile, and the coordinates for the location of the present voyage. 
         [0156]      FIG. 36  depicts a several screen shots of a mobile application for communication between the beacon and smartphones having a second level, a fourth level and a fifth level. There are also menus for describing the passengers on-board, including medical information. To avoid issues stemming from not knowing the menu system, and to accommodate a panicked person in an emergency situation, all menus have a SEND DISTRESS SIGNAL button allowing for immediate navigation to a distress signal menu. From this menu, the user can download the voyage information to the emergency beacon (this is described above as the “message in a bottle” function). If the beacon were separated from the vessel, it would have the pertinent information available to anyone who might recover it. There is also a menu allowing the user to describe the nature of the distress so that the information can be included in the distress signal message and in the “message in a bottle” information. Additionally, there is a button to remotely activate the beacon and thereby control the functionality of the beacon. Weather information would also be available from this menu. 
         [0157]      FIG. 37  depicts a screen shot of the web-based application accessed via the beacon mobile application, illustrating the home level for the dashboard page. Also, another embodiment would use a server to keep track of cell phones using this application that were in range of a cell communications tower. If a user presses the SEND DISTRESS SIGNAL button, the cell phone uses an internet connection to send a distress signal to the server. The server would look for other users that were close to the location of the user that sent the distress signal. The server would then send an alert to those users containing the voyage information. The alert can be in the form of a phone call or an alert message sent through the mobile application. The server can also send alerts to the Coast Guard or equivalent agency, a towing or vessel assist service, search and rescue (SAR) personnel, emergency medical systems (EMS) personnel, the cloud, the Rescue Coordination Center, and/or other land-based resources as necessary. 
         [0158]      FIG. 38  depicts a screen shot of the web-based application accessed via the beacon mobile application, illustrating the distress notifications control page. 
         [0159]      FIG. 39  depicts a screen shot of the web-based application accessed via the beacon mobile application, illustrating the vessel profile page. 
         [0160]      FIG. 40  depicts a screen shot of the web-based application accessed via the beacon mobile application, illustrating the current distress notifications page.
