## Background
CROSS REFERENCES TO RELATED APPLICATIONS
The present application is a non-provisional patent application claiming benefit under 35 U.S.C. §119(e) from U.S. Provisional Application Ser. No. 61/476,577, filed on Apr. 18, 2011, the entire contents of which are hereby expressly incorporated by reference into this disclosure as if set forth fully herein.


BACKGROUND OF THE INVENTION
I. Field of the Invention
The present invention relates generally to anchoring maritime vessels and, more particularly, to anchor surveillance for maritime vessels involving underwater video surveillance.
II. Discussion of the Prior Art
Anchors have been used to secure sailing vessels for hundreds if not thousands of years, and more recently for powered maritime vessels such as motor yachts, cruise ships, and fishing boats. A major challenge in anchoring such maritime vessels is ensuring the anchor has adequate purchase in the sea or lake floor to withstand the various forces acting upon the vessel, such as wind and water, and thus maintain the vessel in a safe and secure state in the given anchored location. Without adequate and sustained anchor purchase, the vessel may slide and move from the given anchored location into other vessels, out to sea, or into the shoreline. In any such case, the unwanted movement of the vessel may cause significant damage if not out-and-out catastrophe for the vessel and potential loss of life for the occupants of the vessel, occupants of nearby vessels, and those on shore.
The present invention is directed at addressing this long-felt challenge to improve the ability to safely and securely anchor maritime vessels.
SUMMARY OF THE INVENTION
The present invention accomplishes this goal by providing anchor surveillance involving underwater video monitoring during and/or after deployment of an anchor to ensure adequate anchor purchase to safely and securely maintain a maritime vessel in a given anchor location. The anchor surveillance of the present invention includes a video camera system capable of capturing video images of an anchor and transmitting them to a remote video display. The video camera system may be coupled directly or indirectly to the anchor and/or anchor rode. The remote video display may be located on the maritime vessel itself and/or a location other than the maritime vessel. Communication of the video images between the video camera system and the remote video display may be accomplished via hard-wire (cables) and/or wireless technology. The video images provide the ability to perform indirect visual inspection of an anchor and/or anchor rode to ensure proper purchase in the sea or lake floor. In so doing, the anchor surveillance of the present invention avoids the need to perform direct visual inspection, which involves physically diving to the anchor to view in person. More importantly, the anchor surveillance of the present invention provides a manner of inspecting an anchor when direct inspection is not desired and/or possible (e.g. during inclement and/or dangerous conditions).
If upon review by an occupant of the vessel the video images are deemed inadequate or otherwise of concern, the anchor may be raised and re-deployed or simply re-set without raising by causing the maritime vessel to move and thus drive the anchor into the sea or lake floor from the previously unset location. Importantly, the occupant(s) of the vessel need not guess as to whether the anchor has been adequately set, and thereby risk having the vessel move in an undesirable and/or unsafe manner. Moreover, an occupant of the vessel need not physically venture into the water in order to directly assess the purchase of the anchor, thereby removing attendant risks of doing so, particularly in inclement or otherwise unsafe conditions (e.g. heavy seas, current, rain, darkness, sharks, etc. . . . ).

DESCRIPTION OF THE PREFERRED EMBODIMENT
Illustrative embodiments of the invention are described below. In the interest of clarity, not all features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual embodiment, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming, but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure. The anchor surveillance systems and related methods disclosed herein boast a variety of inventive features and components that warrant patent protection, both individually and in combination.
FIG. 1 illustrates a maritime vessel 10 having an anchor 12 deployed and set in the sea or lake floor 14 and coupled to the vessel 10 via an anchor rode 16. According to one aspect of the present invention, a floating video camera system 18 is coupled directly to the anchor 12 via a tether 24, in this instance at or near the proximal end which is attached to the anchor rode 16. With reference to FIGS. 1-2, the video camera system 18 has a field of view 20 (shown in dotted lines) sufficient to capture video images which are suitable upon transmission to a remote video display 22 for a user to assess the physical condition and/or position of the anchor 12 (e.g. to ensure the anchor 12 has an adequate purchase in the sea or lake floor 14). The video camera system 18 may also include a light source 21 to provide a field of illumination 23 (shown in dotted lines) to augment or improve the ability to obtain suitable video images, particularly at night and/or if otherwise hard to visualize (e.g. murky water, deep water, etc. . . . ). The video images may be transmitted to the remote video display 22 in any number of suitable manners, including but not limited to hard-wired communication (e.g. via cables, not shown) and/or wireless communication between the video camera system 18 and remote video display 22.
Although shown generically, the maritime vessel 10 is any floating vessel designed to transport people and/or goods by moving the vessel from one point to another. Such floating transport vessels may include, but are not necessarily limited to, a sailboat, a power boat, a combination power/sail boat, a cruise ship, a container ship, and a barge. Although shown as a classic “kedge” type in FIG. 1, the anchor 12 may be any suitable type, including but not limited to a Plow, Danforth, Byers, Hall, Union, D'Hone, ZY-6, AC14, Pool, Bruce, Spek, Stockless, FOB, Klip, CQR, Navy Stockless, and Mushroom, without departing from the scope of the present invention. The anchor rode 16 may be any suitable material for securing the vessel 10 to the anchor 12, including but not limited to a chain, a rope, a combination of chain and rope, cable, etc. . . . The anchor rode 16 is shown in a relatively taut condition, with a relatively high slope and not touching the bottom 14, which may occur while setting the anchor 12 and/or under high winds and/or high current acting upon the maritime vessel 10. Although not shown, it will be appreciated that in the absence of those conditions the anchor rode 16 will typically rest upon the bottom 14 in the vicinity of the anchor 12 before ascending to the maritime vessel 10.
The remote video display 22 may be located anywhere suitable for the occupant(s) of the maritime vessel 10 to perform anchor monitoring depending on their location and desire to perform anchor-monitoring at that location. For example, an occupant may desire to view video images of the anchor 12 during the anchoring process to determine whether the anchor 12 is positioned properly upon deployment and/or during the setting process. “Deployment” describes the process of lowering the anchor 12 to the floor 14 and letting out an appropriate length of anchor rode 16 to achieve a desired scope (i.e. angle of anchor rode 16 between floor 14 and the vessel 10), while “setting” describes the process of dragging the anchor 12 across the floor 14 with sufficient force to drive the purchase element(s) of the anchor 12 to dig into the floor 14 and obtain sufficient purchase to securely maintain the vessel 10 in the desired location.
In either event, the remote video display 22 may be located in the cockpit or elsewhere “above deck” (as shown generally in FIG. 1) such that the occupant can watch the video display 22 during the anchoring process. (Although not shown, other specific “above deck” locations may include, but are not necessarily limited to, the steering pedestal in the cockpit, in or on the cockpit cowling, at or near the bow, at or new the stern, on the mast, boom, etc. . . . ). In this manner, an occupant may contemporaneously determine whether the anchor 12 is positioned to dig and/or is digging into the floor 14 to achieve the desired purchase or, conversely, whether the anchor 12 is fouled up with the anchor rode 16 or other elements on the floor 14 (e.g. rocks, other anchors, etc. . . . ) such that the anchor 12 isn't likely to dig into the floor 14 to establish the desired purchase. If anything other than a desired purchase is obtained, the anchor 12 may be redeployed and/or re-set as appropriate.
The remote video display 22 may also be located “below deck” on vessel 10, which may be particularly useful for monitoring the purchase of the anchor 12 after the anchoring process. Such “below deck” locations may include, but are not necessarily limited to, the navigation station, at or near any secondary steering stations other than in the cockpit (e.g. pilot house), in the stateroom(s), etc. . . . In any case, an occupant can periodically view the below-deck remote video display 22 after the anchoring process to assess the purchase of the anchor 12 and thereby ensure the continued anchor safety of the vessel 10. This may be particularly advantageous and convenient, for example, during inclement weather at night. Rather than go above-deck into the elements, an occupant may simply assess anchor purchase from the convenience and comfort of their below-deck position (e.g. stateroom) periodically throughout the night by viewing the remote video display 22 located below-deck. If a problem is encountered (e.g. the anchor 12 is dragging), only then will they need to go above-deck and redeploy or re-set the anchor 12 as appropriate.
In addition to the “on vessel” locations set forth by way of example above, the remote video display 22 may also be located “off vessel” in accordance with an aspect of the present invention. Such “off vessel” locations may be anywhere suitable for non-occupants to perform anchor monitoring depending on their location and desire to perform anchor-monitoring at that location. Examples of “off vessel” locations, include, but are not necessarily limited to, harbor-master and/or harbor-police stations (on shore and/or on vessels), the home(s) and/or office(s) of the owner of the maritime vessel, etc. . . . In any case, if upon review by a non-occupant the video images are indicative of an anchor problem (e.g. the anchor 12 is dragging) or otherwise of concern, remedial steps may be undertaken or commissioned by the non-occupant (e.g. harbor patrol, owner, etc. . . . ) to re-deployed or re-set the anchor to alleviate the anchor problem or concern.
Whether located on-vessel or off-vessel, the remote video display(s) 12 may take any suitable form according to the present invention. By way of example only, the remote video display 22 may be a dedicated video display device having no other function beyond displaying video information and/or a video display device which is integrated into or used with other instruments or systems. Examples of the latter include, but are not necessarily limited to, computers (e.g. laptops, desktops, etc. . . . ), televisions, chart-plotters, global positioning systems, radar systems, smart-phones (e.g. iPhone, Blackberry, Droid, etc. . . . ) and/or computer tablets (e.g. iPad, etc. . . . ). (As will be described below, if implemented using a smart-phone and/or computer tablet, such devices can be programmed with a software application (or “app”) for controlling aspects of the anchor surveillance system in accordance with an aspect of the present invention.) If combined with a GPS system, the video surveillance system of the present invention may include any number of supplemental alarm features, such as sounding an alarm if the GPS system senses that the vessel 10 has moved more than a predetermined distance, which would be indicative of normal movement and/or swinging of the vessel 10.
The video camera system 18 may be of any suitable type, whether water-proof or within a water-proof housing, and may be equipped with any number of suitable features to improve or facilitate the capture of meaningful video images of the condition and/or position of the anchor 12 when transmitted to the remote video display 22 according to the present invention. The field of view 20 may be either pre-determined or adjustable in order to ensure an optimal perspective of the anchor 12. In the latter case, the field of view 20 may be adjusted remotely by a user (e.g. by an occupant of the vessel) during and/or after the anchoring process, adjusted manually (e.g. by an occupant of the vessel) before the anchor 12 the anchoring process, and/or adjusted automatically during and/or after the anchoring process without the need for user intervention. The view may be panoramic or any other manner (e.g. more focused) without departing from the scope of the present invention.
FIG. 3 illustrates, by way of example only, the video camera system 18 constructed according to one aspect of the invention. The video camera system 18 may include a housing 25 which contains a video camera 27, a power supply 29, a floating element 31, and the light source 21. The shape of the housing 25 may take any number of different forms, including but not limited to generally cylindrical (as shown in FIG. 1), conical, spherical, rectangular and/or any combination thereof, depending upon a variety of factors (e.g. aquadynamics, the manner and extent of the electronics and/or mechanical components forming part of the video camera system 18, etc. . . . ). In this example, the housing 25 includes an upper canister 33 and a lower bulb 35, which may be screwed together or otherwise coupled in any suitably water-tight manner. The canister 33 and bulb 35 may be constructed from any suitable material, including but not limited to plastic for corrosion-resistance, with bulb 35 being translucent or clear to allow the video camera 27 to obtain clear video images according to the present invention. The bulb 35 may also include a water-proof grommet 41 for coupling the tether 24 to the video camera system 18, although it will be appreciated that the tether 24 may be coupled to the housing 25 in any number of suitable manners without departing from the scope of the invention. Though not shown, it is contemplated that the housing 25 may include a spooling mechanism (automated or manual) to selectively retract the tether 24 into the housing 25 to shorten the tether 24 and thereby lower the video camera system 18 towards the anchor 12, as well as selectively pay out the tether 24 from the housing 25 to lengthen the tether 24 and thereby raise the video camera system 18 relative to the anchor 12.
The video camera 27 may include a lens element 37 and a video capture element 37 which cooperate to obtain and transmit video images according to the present invention. The lens element 37 may be non-adjustable and thus provide a predetermined field of view 20 or adjustable (manually and/or automatically) to optimize the field of view 20 and/or change the type of view (e.g. focused, panoramic, etc. . . . ), as described above. The power supply 29 is electrically coupled to the video camera 27 and light source 21 to drive the operation of the associated electronics. The power supply 29 may be any number of suitable power supplies, including but not limited to off-the-shelf batteries and/or a custom, rechargeable battery pack. Although shown by way of example, it will be appreciated that the video camera system 18 may include more or less components than shown in FIG. 3 without departing from the scope of the invention. For example, the power supply 29 may be omitted if the video camera system 18 is hard-wired to the vessel 10, such as will be described below with reference to FIG. 4.
The floating element 31 may be any suitable device or structure which causes the video camera system 18 to be positioned generally above the anchor 12, including but not limited to cork, Styrofoam, a structure having one or more enclosed pocket(s) of air or other gas. Although not shown, as will be described in greater detail below, the video camera system 18 may also be equipped with a water source capable of directing water towards the anchor 12 for the purpose of clearing away debris to improve the ability to capture meaningful video images. In this instance, the water source itself may augment the ability of the video camera system 18 to be maintained generally vertically above the anchor 12, due to the upward forces exerted upon the video camera system 18 by the downward flowing water.
The light source 21 may comprise any type of light source capable of sufficiently illuminating the anchor 12 to obtain meaningful video images according to the present invention, including but not limited to light emitting diode (LED) lights, plasma lights, halogen lights, and HID lights. With reference to FIGS. 2-3, the light source 21 is shown, by way of example only, extending along the perimeter of the housing 25 in a generally circular or “band-like” fashion. This configuration is intended to cause the field of illumination 23 to take a generally conical shape to encompass not only the anchor 12 but also the surrounding region. It will be appreciated, however, that the light source 21 may be provided as a number of individual lights, and that the field of illumination 21 may take any number of additional shapes without departing from the scope of the present invention.
FIG. 4 illustrates another aspect of the present invention, wherein the video camera system 18 is of the type shown and described above with reference to FIGS. 1-3, but communicatively coupled to the vessel 10 via a cable 28. The cable 28 may include the necessary electrical wiring and/or fiber optics to transmit the video images from the floating video camera system 18 to the remote video display 22. The cable 28 may be directly coupled to the remote video display 22 and/or wirelessly linked to the remote video display 22 (e.g. via a wireless router located on the vessel 10 and coupled to the cable 28). The cable 28 may also include the necessary electrical wiring and/or fiber optics to communicate control instructions from the vessel 10 (e.g. adjusting the field of view 20, turning the light source 21 off and on, etc. . . . ), as well as to supply power to the floating video camera system 18 for the purpose of running the on-board electronics (e.g. video camera 27, light source 21, etc. . . . ). As noted above, providing power to the video camera system 18 in this manner may obviate the need for the on-board power supply 29 shown by way of example in FIG. 3.
FIG. 5 illustrates a further aspect of the present invention, wherein a floating communications module 30 may be coupled to the video camera system 18 via a tether 32. The communications module 30 may be communicatively coupled to the video camera system 18 and contain the necessary electronics in order to wirelessly transmit video images to the remote video display 22. The communications module 30 may also include a light 43 in order to alert neighboring vessels as to the location of the anchor 12, which may be particularly advantageous at night so newly arriving vessels avoid anchoring too close to the anchor 12 of the vessel 10. Communications module 30 may optionally include at least one solar cell (not shown) and at least one battery (not shown) configured to at least partially power the light 43 and the on-board electronics. The communications device 30 may be equipped with any suitable device or structure which causes it to float at or near the surface of the water, including but not limited to cork, Styrofoam, a structure having one or more enclosed pocket(s) of air or other gas. The tether 32 may be fixed or retractable without departing from the scope of the invention. If retractable, the tether 32 may automatically adjust to the appropriate length with sufficient tension to keep the video camera system 18 generally above the anchor 12. This may eliminate or minimize the need to have a separate floating element 31 as part of the video camera system 18, shown by way of example only in FIG. 3.
FIG. 6 illustrates a further aspect of the present invention, wherein the video camera system 18 may be indirectly coupled to the anchor rode 16 via a tether 34 to maintain the video camera system 18 generally vertically beneath the coupling point. To facilitate this, the video camera system 18 may include a weight or other ballast to cause it hang generally vertically as shown in FIG. 6. The tether 34 may be coupled directly to the anchor rode 16 at a predetermined location along its length using any number of suitable coupling features, including but limited to snap hooks, shackles, chain links, etc. . . . The video camera system 18 may be positioned along the anchor rode 16 to optimize the field of view 20 to capture and provide the most accurate and meaningful video images of the anchor 12, particularly if the field of view 20 isn't remotely adjustable after the anchor 12 has been deployed and/or set. Of course, the field of view 20 of the video camera system 18 (and field of illumination, as well, although not shown) may be adjustable to be directional, as shown, in order to obtain video images of the anchor 12 which is offset horizontally relative to the video camera system 18.
FIG. 7 illustrates a further aspect of the present invention, wherein the video camera system 18 may be indirectly coupled to the anchor rode 16 via a traveler system 36 to maintain the video camera system 18 generally vertically beneath the coupling point. In this aspect of the present invention, the tether 34 of FIG. 6 is coupled to the traveler system 36 (versus the anchor rode 16 itself). The traveler system 36 is capable of traversing along the anchor rode 16 to selectively position the video camera system 18 at a desired location along the length of the anchor rode 16. The traveler system 36 may be motorized and/or manually movable without departing from the scope of the present invention. If motorized, the traveler system 36 may be powered in any number of suitable manners (e.g. electrical, pneumatic, hydraulic, etc. . . . ) and include any number of suitable purchase features for providing adequate purchase between the traveler system 36 and the anchor rode 16 such that the traveler system 36 can be moved along the anchor rode 16 (e.g. chain rollers, opposed rubber rollers, etc. . . . ). If manually movable, the traveler system 36 may simply include a weighted roller such that the video camera system 18 may descend along the anchor rode 16 under the force of gravity (with or without a weight in the video camera system 18). The traveler system 36 may include a tether 38, which may be multi-purpose in function. In one aspect, the tether 38 may be used to established electrical communications for control if the traveler system 36 is motorized. In another, more basic aspect, the tether 38 may be used to manually control the ascent and descent of the traveler system 36 if it is either not motorized or the motor is malfunctioning.
The traveler system 26 may be provided in any number of suitable fashions without departing from the scope of the present invention. FIGS. 8A-8C illustrate, by way of example only, the traveler system 36 according to one aspect of the present invention. The traveler system 36 includes a roller 40 having a generally circular shape about its periphery and a series of engagement features 42 for engaging with the anchor rode 16. In this example, the anchor rode 16 is a length of chain, such that the engagement features 42 are shaped to receive and engage the links forming the chain (much like a Windlass) and thereby establish sufficient purchase for the traveler 36 to traverse up or down the anchor rode 16. FIGS. 9A-9C illustrate, by way of example only, the traveler system 36 according to another aspect of the present invention. The traveler system 36 includes a pair of opposed rollers 44 disposed on either side of the anchor rode 16. The rollers 44 are preferably biased towards one another in order to provide sufficient purchase between the traveler system 36 and the anchor rode 16. The rollers 44 may traverse up and/or down the anchor rode 16 manually under the weight of the video camera system 18 and/or the traveler system 36 by manually tending the tether 38. The rollers 44 may also be powered to drive the traveler 36 up or down the anchor rode 16, such as if the tether 38 is equipped to deliver electrical, pneumatic, hydraulic or other means of powering the traveler system 36 along the anchor rode 16 according to the present invention.
The anchor surveillance systems of FIGS. 1-9 are all indirectly coupled to the anchor 12 (FIGS. 1-6) or the anchor rode 16 (FIGS. 7-9). It will be appreciated, however, that the video camera system 18 may also be directly coupled to the anchor 12 and/or anchor rode 16 without departing from the scope of the present invention.
FIGS. 10-11 illustrate the feature of directly coupling the video camera system 18 to the anchor rode 16 according to one aspect of the present invention. In this instance, this is accomplished by providing the video camera system 18 with a housing 35 of split-shell construction. As best shown in FIG. 11 (side view) and FIG. 12 (partial cross-section), the housing 25 includes a first half 46 and a second half 48 coupled together via a hinge 50. Due to the hinged relation, the first half 46 and second half 48 may be selectively moved away from one another about the axis of the hinge 50 to “open” the housing 25. With the housing 25 in the open position, it may be positioned at any desired location along the anchor rode 16. The first half 46 and second half 48 may then be moved towards one another about the axis of the hinge 50 in order to “close” the housing 25 about the anchor rode 16.
As best viewed in FIG. 12, to facilitate this direct coupling, the interior of the first half 46 and/or second half 48 may be equipped with a deformable section 52. The deformable section 52 is designed to accommodate anchor rodes of various diameters and/or cross-sectional shapes while still providing a snug fit between the housing 25 and the anchor rode 16. The deformable section 52 may be constructed in any number of suitable manners with any number of suitable materials, including but not limited to a rubber membrane (inflatable or non-inflatable), foam (shape memory or otherwise), etc. . . . If inflatable, the deformable membrane 52 may be selectively deflated in order to move the housing 25 up or down the anchor rode 16 (before or after the anchoring process) and thereafter re-inflated to fix the video camera system 18 in the new position.
