DETAILED DESCRIPTION

(12) Referring now to FIG. 1, a crowded harbor 10 is shown having a number of mooring balls 12 located throughout the harbor to which sailing vessels 14 are moored. It will be seen that due to the densely packed harbor it is very difficult for an incoming vessel 16 to be able to locate a particular mooring ball, here shown at 18, due to the number of boats in the way and due to the similarity of all of the mooring balls 12.

(13) While the moorings themselves are numbered or provided with other indicia and while if the boater is familiar with the harbor and knows the location of boats adjacent his mooring, it is still nonetheless difficult at times for the boater to ascertain which mooring is his. The problem exacerbated when boats that usually sit around his mooring have left their moorings. Thus there is no visual cue as to which of the many moorings in the crowded mooring field is the boater's mooring.

(14) In order for the mooring beacon 18 to be identified, a boater on a vessel 16 activates the transponder 17 to wirelessly activate the associated mooring beacon 18 through an transmission 20 which causes a high intensity light source 22 to illuminate. This illumination may be visible for at least 100 yards and permits the boater to maneuver his vessel as illustrated by the dotted line 24 towards his mooring beacon 18.

(15) The mooring beacon 18 is of sufficient intensity and omnidirectionality that regardless of the crowding of the harbor and orientation of the mooring beacon, the mooring beacon is easily visible not only at night but also in fog and during the day.

(16) As illustrated in FIG. 2, the mooring beacon 18 is comprised of a shaft 30 that extends through a float 32 in and carries a receiver unit 34 adapted to receive the wireless signals from the wireless transmitter on a vessel entering the harbor. This signal may be coded such that the only mooring beacon 18 that has its high power light source activated is the one that corresponds in code or frequency to the transponder actuated. On top of the receiver housing is a high intensity omnidirectional light source 36 which is visible at large distances due to the high intensity of the light source 36, be it a strobe light in one embodiment or a plurality of LEDs aimed around the compass points to provide 360 coverage. The bottom portion 40 of the shaft 30 is provided with a battery package 42 which will be described hereinafter but whose function is not only to power the mooring beacon 18 but also to provide a ballast to make sure that the shaft 30 is in an upright position as it floats on the surface the ocean or lake.

(17) Referring to FIG. 3, the upper portion of the mooring beacon 18 of FIG. 2 is shown in which at the top of the shaft 30 is a waterproof housing 34 which carries a receiver for receiving coded signals from a transponder. Housing 34 also includes switching circuits for connecting the power from the battery package 42 carried at the base of the shaft 30 to both the receiver within housing 34 and also to the high intensity light source 36 which is illustrated as a flash lamp strobe. The receiver may be a conventional receiver such as found in garage door openers along with conventional switches normally used in such applications.

(18) It be appreciated that the housing and all components are made waterproof so that they will operate at least for a season and longer. The components may be hermetically sealed.

(19) Referring back to FIG. 2, in one embodiment, the shaft 30 and attendant hardware performs the function of a mooring stick which is attached to a mooring ball by a chain. After the boater identifies his mooring and comes up to it, he may pluck the mooring stick out of the water and secure the mooring ball to a bow cleat. Is important to note that the weight of the entire mooring with shaft 30, high intensity light source 36, receiver 34 and battery package 42 is kept under 10 pounds, and preferably lighter so that it may be easily brought aboard the boat.

(20) More particularly, and referring now to FIG. 4, the shaft 30 is shown to pass through the float 32 such that an upper portion 50 extends upwardly from the float 32 by a distance illustrated by arrow 54 of approximately 3 feet in one embodiment. Beneath the float is a portion of the shaft 56 having a battery package 42 secured to the distal end of shaft 30, with shaft portion 56 extending as illustrated by arrow 58 1 to 2 feet below the float 32. In one embodiment, the weight of the battery package is between 4 and 10 pounds to give sufficient righting moment to the mooring such that it remains upright in all sea conditions.

(21) The mooring beacon 18 is provided with an on-off switch 60 such that the mooring beacon can be actuated when placed adjacent a mooring ball. Here it will be seen that the 360 degree high intensity light source 36 may be in the form of a strobe light which is visible for a mile or more. Alternatively, and as shown in FIG. 7, the high intensity light source may be made of a plurality of light emitting diodes mounted around the periphery of a circular support so that they face outwardly and provide 360 degree visibility. If the individual light emitting diodes are not sufficiently intense, they may be located in mini flashlight modules such that the light emitted in one direction is spread out by the number flash light modules. Note that each flashlight module may incorporate a number of LEDs. The LEDs may be programmed to blink in a strobe-like manner to be easily visible. The LEDs may be programmed to blink a finite number of times, such as not more than 5 blinks for a single activation. Controlling the blinking limits light pollution in the harbor.

(22) As illustrated in FIG. 5 a typical transponder 62 is shown with an activation button 64 to cause the transponder 62 to transmit a coded signal which is picked up by the mooring beacon 18.

(23) Referring now to FIG. 6, a dual battery pack 70 includes a pair of batteries 72 connected in series, the output of which is 3 V and a number of batteries 74 connected in series to produce a combined output of 9 V. The output from the low voltage source over is coupled to a switch module 80 which is activated by a receiver 34 (not shown in this figure) so that under normal operation the low-voltage 3 V is applied to a receiver 34 mounted atop the shaft 30.

(24) When the mooring is actuated by a remote RF signal, switch module 80 connects the high-voltage from batteries 74 to power the high intensity light source 36. When this light source 36 is a strobe as illustrated, its power drain is significant and requires the higher voltage to sustain his high power output.

(25) However, as illustrated in FIG. 7, if the high intensity light source 36 may be comprised of LED modules 86 each pointed in a different direction around a periphery, then the drain on battery 74 may be significantly reduced while at the same time providing for the required high intensity omnidirectional output. As mentioned above, if individual light emitting diodes mounted around the periphery of a support, for instance support 90, are insufficiently bright to provide visibility over long ranges, aggregates of LEDs may be mounted in modules to provide high intensity light in one direction. In this case a number of these modules may be arrayed around in a circle on support 90 such that while the beam width is relatively narrow for each of these modules, the use of multiple modules pointing in different directions permits omnidirectional high intensity light to be propagated out across the harbor.

(26) Referring now to FIG. 8A, in one embodiment, a housing 100 houses a number of cylindrical batteries 102 in a triangular configuration. The batteries are kept in place by spacers 104 so as to make sure they do not become dislodged. Referring to FIG. 8B, housing 100 is shown with batteries 102 mounted vertically within the housing and connected by contacts 106 and 108 to keep the batteries in place. The batteries may be replaced through a lower portion 110 of housing 100 which is anchored in place through a pin or screw 112. In another embodiment, a single battery may be utilized to power the mooring beacon 18, if sized properly. The battery or batteries forming the ballast of the mooring beacon 18 may be rechargeable and may be recharged from a connection port (not shown) mounted at an upper portion 50 of the shaft 30.

(27) It will be appreciated that what is provided is a mooring beacon which floats next to a mooring ball and is tethered thereto such that the mooring beacon is actuated remotely by transponder and is provided with a high intensity omnidirectional light source visible over large distances, thus to be able to identify the particular mooring for the boater seeking to moor his boat. In one embodiment, the receiver utilized to activate the high intensity light source turns off the high intensity light source after predetermined time so as to minimize battery drain.

(28) With the batteries located at the distal end of the shaft of the mooring beacon and since these batteries must of necessity weigh enough to keep the mooring shaft vertically oriented, these batteries are designed not only to ballast the mooring beacon but also to permit season-long usage of the mooring beacon without replacement. It is noted that for marine use, all of the above components are waterproof and sealed such that corrosion is avoided as well as internal shorting for the components of the mooring beacon.

(29) While the above operation has been described in connection with mooring balls, it will be appreciated that this floating device may be anchored to a pier or dock slip to indicate to an incoming boater where he or she is to dock his vessel. The actuation of the mooring beacon is the same as discussed hereinbefore. Moreover, these mooring beacons can be actuated for instance by a dockmaster or harbormaster to indicate which of the slips is available for use. In this case, the remote control unit is utilized to actuate a particular mooring beacon, which actuation is under the control of the harbormaster or dockmaster instead of the operator of the vessel.

(30) More particularly, and referring now to FIG. 9, it will be seen that a dock house 120 is provided with a number of transponders 122. These transponders correspond to docks 1-5, with the transponders forming a head end control system and actuated to actuate a corresponding high intensity light source at the end of the appropriate dock. Here a number of docks 124 are illustrated as being Docks 1, 2, 3, 4, 5. At the end of each of these docks is an illuminable remote-controllable light source on a pole such as indicated at 126, 128, 130, 132 and 134. When the dockmaster wishes to indicate that the that Dock Number 2 is available, he activates the transponder 122 corresponding to Dock Number 2, at which point the high intensity light source at 128 is illuminated to indicate the dock to which a boater is to tie up. Thus, the vessel travels along dotted line 140 to the near side of Dock Number 2 as illustrated.

(31) In this manner the dockmaster or harbormaster can indicate which dock is available for an incoming vessel. In this case either the mooring beacon can be floated at the end of the dock or the shaft portion merely physically attached to the end of the dock, with the operation of the beacon being as mentioned hereinbefore.

(32) While the present invention has been described in connection with the preferred embodiments of the various figures, it is to be understood that other similar embodiments may be used or modifications or additions may be made to the described embodiment for performing the same function of the present invention without deviating therefrom. Therefore, the present invention should not be limited to any single embodiment, but rather construed in breadth and scope in accordance with the recitation of the appended claims.
