TECHNICAL FIELD

The present disclosure relates generally to a system for use with digital image capturing devices (DICDs), and, more specifically, to an underwater system for housing such devices.

BACKGROUND

Operating a DICD in an underwater environment may be desirable in a variety of situations. However, contact between the lens(es) of the DICD and the water can create distortion and compromise image quality. To combat this issue, the present disclosure describes various waterproof, underwater systems that are configured to house (or otherwise accommodate) DICDs to not only prevent damage to the DICD, but also increase separation between the lens(es) of the DICD and the water to reduce distortion.

SUMMARY

In one aspect of the present disclosure, an underwater system is described for use with a digital image capturing device (DICD) in underwater environments. The underwater system includes a housing with first and second housing portions, and a base. The first housing portion includes a first dome, and the second housing portion includes a second dome. The second housing portion is directly connectable to the first housing portion such that the housing is reconfigurable between an open configuration, in which the DICD is insertable into and removable from the housing, and a closed configuration, in which the first and second housing portions collectively define a waterproof interior cavity. The base is positioned within the waterproof interior cavity and is configured to receive the DICD such that electrical communication is established between the base and the DICD.

The first and second domes define first and second centerpoints, respectively, that collectively define a first axis. In certain embodiments, the first and second housing portions may be connectable such that the base is separated from the first axis along a second axis that extends orthogonally in relation to the first axis.

In certain embodiments, the first and second housing portions may be pivotally connected to each other. For example, the housing may further include a pivot member that connects the first and second housing portions. In such embodiments, the pivot member may define a pivot axis that extends in orthogonal relation to the first axis (defined by the centerpoints of the first and second domes).

In certain embodiments, the housing may further include at least one closure member that is movable between a first position, in which the first and second housing portions are relatively movable, and a second position, in which the first and second housing portions are fixed in relation to each other.

In certain embodiments, the closure member may be slidable in relation to the first and second housing portions during movement between the first and second positions.

In certain embodiments, the closure member may be configured to approximate the first and second housing portions during movement from the first position to the second position.

In certain embodiments, the closure member may include a clamp.

In certain embodiments, the first housing portion may define a first planar surface and the second housing portion may define a second planar surface. In such embodiments, the first and second planar surfaces may face each other, and may correspond in configuration, such that the first and second planar surfaces form a seal upon movement of the housing into the closed configuration.

In certain embodiments, the housing may further include a plurality of fingers that are configured for engagement with an accessory.

In certain embodiments, the fingers may be movable between a first position, in which the fingers extend from the housing, and a second position, in which the fingers are concealed by (or within) the housing.

In another aspect of the present disclosure, an underwater system is described for use with a DICD in underwater environments. The underwater system includes a housing with first and second housing portions, and a base. The second housing portion is connectable to the first housing portion such that the housing is reconfigurable between an open configuration, in which the DICD is insertable into and removable from the housing, and a closed configuration, in which the first and second housing portions collectively define a waterproof interior cavity. The base is positioned within the waterproof interior cavity and is wirelessly connectable to the DICD to facilitate control over the DICD.

In certain embodiments, the base may include a power source (e.g., a replaceable and/or rechargeable battery).

In another aspect of the present disclosure, a housing is described for a digital image capturing device (DICD) including first and second lenses having respective first and second fields-of-view. The housing is configured to receive the DICD to facilitate use in underwater environments, and includes at least one optically clear component, and at least one optically unclear component (i.e., at least one component that is not optically clear). The housing is configured such that the at least one optically clear component is positioned within the first field-of-view and/or the second field-of-view, and the at least one optically unclear component is positioned outside of the first and second fields-of-view.

In certain embodiments, the at least one optically clear component may include at least one dome. For example, the optically clear component may include a first dome and a second dome. In such embodiments, the first and second domes may define diameters that are substantially within the range of approximately 2″ to approximately 8″ (e.g., 4″), and may each define centerpoints.

In certain embodiments, it is envisioned that the centerpoints may define a first axis that extends in generally parallel relation to optical axes defined by the first and second lenses.

In certain embodiments, the at least one optically unclear component may include at least one external actuator.

In certain embodiments, the actuation mechanism may be configured for movement between an inactive position, in which the actuation mechanism is spaced from the button on the DICD, an active position, in which the actuation mechanism engages the button on the DICD, and an intermediate position, in which the actuation mechanism is positioned between the inactive position and the active position.

In certain embodiments, the actuation mechanism may be configured for movement from the inactive position into the intermediate position upon closure of the underwater system.

DETAILED DESCRIPTION

The present disclosure describes various embodiments of an underwater system that is configured to house (or otherwise accommodate) a variety of DICDs (e.g., DICDs having different configurations). The presently disclosed underwater systems includes a housing with a pair of optically clear domes, which may be configured as discrete structures, or integrally (e.g., monolithically formed), such as via molding. In one particular embodiment, the housing includes discrete housing portions that are relatively movable to transition the housing between an open configuration, in which the DICD is insertable into (and removable from) the housing, and a closed configuration, in which a watertight internal cavity is established within the housing.

In one embodiment, the presently disclosed housing includes a series of external actuators (e.g., buttons) that are configured in correspondence with buttons included on the DICD (e.g., the shutter button, the mode button, etc.) such that the external actuators are usable to control operation of the DICD. Additionally, or alternatively, it is envisioned that the underwater system may include a base in wireless communication with the DICD to allow the DICD to be controlled remotely. For example, by positioning both the DICD and the base within the watertight internal cavity, it is envisioned that wireless communication between the base and the DICD may be supported by Bluetooth or other such wireless communication protocols.

FIGS.1A-2illustrate an example digital image capture device (DICD)100. The DICD100may include a body102having various indicators (such as LEDs, displays, and the like), various input mechanisms (such as buttons, switches, and touchscreen mechanisms), and electronics (e.g., imaging electronics, power electronics, etc.) internal to the body102for capturing images and/or performing other functions. The DICD100may be configured to capture images and video and to store captured images and video for subsequent display or playback.

In the particular embodiment illustrated inFIGS.1A-2, the DICD100is configured to capture spherical images, and accordingly, includes a first image capture device104A and a second image capture device104B. The first image capture device104A defines a first field-of-view106A (FIG.2) and includes a first lens108A that receives and directs light onto a first image sensor110A. Similarly, the second image capture device104B defines a second field-of-view106B (FIG.2) and includes a second lens108B that receives and directs light onto a second image sensor110B. To facilitate the capture of spherical images, the image capture devices104A,104B (and related components) may be arranged in a back-to-back (Janus) configuration such that the lenses108A,108B face in generally opposite directions.

The DICD100may include various indicators, including LED lights112an LED display114. The DICD100may also include buttons116configured to allow a user of the DICD100to interact with the DICD100, to turn the DICD100on, and to otherwise configure the operating mode of the DICD100. In the particular embodiment seen inFIGS.1A-2, for example, the DICD100includes a shutter button116A and a mode button116B. It should be appreciated, however, that, in alternate embodiments, the DICD100may include additional buttons116to support and/or control additional functionality. The DICD100may also include one or more microphones118configured to receive and record audio signals (e.g., voice or other audio commands) in conjunction with recording video. A side of the DICD100may include an I/O interface120. The DICD100may also include an interactive display122that allows for interaction with the DICD100while simultaneously displaying information on a surface of the DICD100.

The body102of the DICD100is configured to encompass and protect the internal electronics which are further described in later sections. In the present example, the body102exterior includes six surfaces (i.e., a front face102A, a rear face102B (FIG.1B), a left face102C (FIG.1A), a right face102D, a top face102E, and a bottom face102F). In the illustrated embodiment, the surfaces102A-102F collectively impart a generally rectangular cuboid configuration to the body102. Other configurations for the body102, however, would not be beyond the scope of the present disclosure. The DICD100may be made of a rigid material such as plastic, aluminum, steel, or fiberglass. Additional features, such as the features described above, may be affixed to the exterior. In some embodiments, the DICD100described herein includes features other than those described below. For example, instead of a single I/O interface120, the DICD100may include additional interfaces120or different interface features.

Although not expressly shown inFIGS.1A-2, in some implementations, the DICD100may include one or more image sensors, such as a charge-coupled device (CCD) sensor, an active pixel sensor (APS), a complementary metal-oxide-semiconductor (CMOS) sensor, an N-type metal-oxide-semiconductor (NMOS) sensor, and/or any other image sensor or combination of image sensors. Although not illustrated, in various embodiments, the DICD100may include other additional electrical components (e.g., an image processor, camera SoC (system-on-chip), etc.), which may be included on one or more circuit boards within the camera body102.

Although not expressly shown inFIGS.1A-2, the DICD100may include one or more other information sources or sensors, such as an inertial measurement unit (IMU), a global positioning system (GPS) receiver component, a pressure sensor, a temperature sensor, a heart rate sensor, or any other unit, or combination of units, that may be included in an image capture apparatus.

The DICD100may interface with or communicate with an external device, such as an external user interface device, via a wired or wireless computing communication link (not shown). The user interface device may, for example, be the personal computing device described below with respect toFIG.3B. Any number of computing communication links may be used. The computing communication link may be a direct computing communication link or an indirect computing communication link, such as a link including another device or a network, such as the Internet. In some implementations, the computing communication link may be a Wi-Fi link, an infrared link, a Bluetooth (BT) link, a cellular link, a ZigBee link, a near field communications (NFC) link, such as an ISO/IEC 20643 protocol link, an Advanced Network Technology interoperability (ANT+) link, and/or any other wireless communications link or combination of links. In some implementations, the computing communication link may be an HDMI link, a USB link, a digital video interface link, a display port interface link, such as a Video Electronics Standards Association (VESA) digital display interface link, an Ethernet link, a Thunderbolt link, and/or other wired computing communication link.

The DICD100may transmit images, such as panoramic images, or portions thereof, to the user interface device (not shown) via the computing communication link, and the user interface device may store, process, display, or a combination thereof the panoramic images.

The user interface device may be a computing device, such as a smartphone, a tablet computer, a phablet, a smart watch, a portable computer, and/or another device or combination of devices configured to receive user input, communicate information with the DICD100via the computing communication link, or receive user input and communicate information with the DICD100via the computing communication link.

The user interface device may display, or otherwise present, content, such as images or video, acquired by the DICD100. For example, a display of the user interface device may be a viewport into the three-dimensional space represented by the panoramic images or video captured or created by the DICD100.

The user interface device may communicate information, such as metadata, to the DICD100. For example, the user interface device may send orientation information of the user interface device with respect to a defined coordinate system to the DICD100, such that the DICD100may determine an orientation of the user interface device relative to the DICD100. Based on the determined orientation, the DICD100may identify a portion of the panoramic images or video captured by the DICD100for the DICD100to send to the user interface device for presentation as the viewport. In some implementations, based on the determined orientation, the DICD100may determine the location of the user interface device and/or the dimensions for viewing of a portion of the panoramic images or video.

The user interface device may implement or execute one or more applications to manage or control the DICD100. For example, the user interface device may include an application for controlling camera configuration, video acquisition, video display, or any other configurable or controllable aspect of the DICD100.

The user interface device, such as via an application, may generate and share, such as via a cloud-based or social media service, one or more images, or short video clips, such as in response to user input. In some implementations, the user interface device, such as via an application, may remotely control the DICD100, such as in response to user input.

The user interface device, such as via an application, may display unprocessed or minimally processed images or video captured by the DICD100contemporaneously with capturing the images or video by the DICD100, such as for shot framing, which may be referred to herein as a live preview, and which may be performed in response to user input. In some implementations, the user interface device, such as via an application, may mark one or more key moments contemporaneously with capturing the images or video by the DICD100, such as with a tag, such as in response to user input.

The user interface device, such as via an application, may display, or otherwise present, marks or tags associated with images or video, such as in response to user input. For example, marks may be presented in a camera roll application for location review and/or playback of video highlights.

The user interface device, such as via an application, may wirelessly control camera software, hardware, or both. For example, the user interface device may include a web-based graphical interface accessible by a user for selecting a live or previously recorded video stream from the DICD100for display on the user interface device.

The user interface device may receive information indicating a user setting, such as an image resolution setting (e.g., 3840 pixels by 2160 pixels), a frame rate setting (e.g., 60 frames per second (fps)), a location setting, and/or a context setting, which may indicate an activity, such as mountain biking, in response to user input, and may communicate the settings, or related information, to the DICD100.

With reference now toFIG.2in particular, the fields-of-view106A,106B of the lenses108A,108B are shown above and below boundaries124A,124B, respectively. Behind the first lens108A, the first image sensor110A may capture a first hyper-hemispherical image plane from light entering the first lens108A, and behind the second lens108B, the second image sensor110B may capture a second hyper-hemispherical image plane from light entering the second lens108B. One or more areas, such as blind spots126,128, may be outside of the fields-of-view106A,106B of the lenses108A,108B so as to define a “dead zone”130. In the dead zone130, light may be obscured from the lenses108A,108B and the corresponding image sensors110A,110B, and content in the blind spots126,128may be omitted from capture. In some implementations, the image capture devices104A,104B may be configured to minimize the blind spots126,128.

The fields-of-view106A,106B may overlap. Stitch points132,134, proximal to the DICD100, at which the fields-of-view106A,106B overlap may be referred to herein as overlap points or stitch points. Content captured by the respective lenses108A,108B, distal to the stitch points132,134, may overlap.

Images contemporaneously captured by the respective image sensors110A,110B may be combined to form a combined image. Combining the respective images may include correlating the overlapping regions captured by the respective image sensors110A,110B, aligning the captured fields-of-view106A,106B, and stitching the images together to form a cohesive combined image.

A slight change in the alignment, such as position and/or tilt, of the lenses108A,108B, the image sensors110A,110B, or both, may change the relative positions of their respective fields-of-view106A,106B and the locations of the stitch points132,134. A change in alignment may affect the size of the blind spots126,128, which may include changing the size of the blind spots126,128unequally.

Incomplete or inaccurate information indicating the alignment of the image capture devices104A,104B, such as the locations of the stitch points132,134, may decrease the accuracy, efficiency, or both of generating a combined image. In some implementations, the DICD100may maintain information indicating the location and orientation of the lenses108A,108B and the image sensors110A,110B such that the fields-of-view106A,106B, stitch points132,134, or both may be accurately determined, which may improve the accuracy, efficiency, or both of generating a combined image.

The lenses108A,108B define optical axes XA, XB (FIG.1A), respectively, which may be substantially antiparallel to each other, such that the respective axes may be within a tolerance such as 1%, 3%, 5%, 10%, and/or other tolerances. In some implementations, the image sensors110A,110B may be substantially perpendicular to the optical axes XA, XB through their respective lenses108A,108B, such that the image sensors may be perpendicular to the respective optical axes XA, XB to within a tolerance such as 1%, 3%, 5%, 10%, and/or other tolerances.

The lenses108A,108B may be laterally offset from each other, may be off-center from a central axis of the DICD100, or may be laterally offset and off-center from the central axis. As compared to DICDs with back-to-back lenses, such as lenses aligned along the same axis, DICDs including laterally offset lenses may include substantially reduced thickness relative to the lengths of the lens barrels securing the lenses. For example, the overall thickness of the DICD100may be close to the length of a single lens barrel as opposed to twice the length of a single lens barrel as in a back-to-back configuration. Reducing the lateral distance between the lenses108A,108B may improve the overlap in the fields-of-view106A,106B.

Images or frames captured by the image capture devices104A,104B may be combined, merged, or stitched together to produce a combined image, such as a spherical or panoramic image, which may be an equirectangular planar image. In some implementations, generating a combined image may include three-dimensional, or spatiotemporal, noise reduction (3DNR). In some implementations, pixels along the stitch boundary may be matched accurately to minimize boundary discontinuities.’

With reference now toFIGS.4-11, one embodiment of an underwater system for the DICD100, which is identified by the reference character400, will be discussed. The underwater system400is configured for use in underwater environments, and includes a housing402defining an internal, watertight cavity404(FIG.5) that is configured to receive the DICD100. The housing may include (e.g., may be formed partially or entirely from) any suitable optically clear material (i.e., any material that does not interfere with, or negatively impact, the capture or quality of digital images), and may be formed through any suitable manufacturing process (e.g., molding). For example, in one particular embodiment, it is envisioned that the housing402may include (e.g., may be formed partially or entirely from) polycarbonate.

The housing402includes discrete (first and second) housing portions406A,406B that are connected via an engagement structure408, which allows for reconfiguration of the housing402between open and closed configurations (e.g., for insertion, removal, and use of the DICD100). In the illustrated embodiment, for example, the engagement structure408includes a hinge410that connects the housing portions406A,406B in a clamshell-style arrangement and allows for pivotable relative movement between the housing portions406A,406B. To establish the watertight cavity404, and guard against the unwanted intrusion of moisture in the closed configuration, it is envisioned that the housing portions406A,406B may include corresponding structures and/or surfaces that are configured for engagement so as to define a sealed interface412(FIG.5). For example, the housing portions406A,406B may include corresponding flanges414A,414B defining planar surfaces416A,416B, respectively, as seen inFIG.4. Additionally, or alternatively, it is envisioned that the housing402may include a sealing member (e.g., a rubberized gasket, O-ring, etc.) at the interface412.

To maintain the closed configuration, it is envisioned that the housing402may include one or more locking members418. In the illustrated embodiment, for example, the housing402may include one or more sliders420that are slidably connected to the housing portion406A (and/or the housing portion406B) for movement between a locked position, in which the slider(s)420are configured and positioned to maintain the closed configuration, and an unlocked position, in which the slider(s)420are configured and positioned to allow for movement of the housing402into the open configuration. Additionally, or alternatively, it is envisioned that the locking member(s)418may include a latch, clamp (e.g., an over-center clamp), or other such mechanism, structure, or member to secure the housing portions406A,406B in relation to one another. It is further envisioned that the locking member(s)418may facilitate reconfiguration of the housing402between the open and closed configurations. For example, in the context of the slider(s)420(and/or the clamp), the slider(s)420(and/or the clamp) may be configured to approximate the housing portions406A,406B during movement from the unlocked position to the locked position, and to cause (or otherwise facilitate) separation of the housing portions406A,406B during movement from the locked position to the unlocked position.

To offset the buoyancy resulting from the capture of air within the watertight cavity404, it is envisioned that the underwater system400(e.g., the housing402) may be weighted, or, alternatively, that the underwater system400(e.g., the housing402) may be configured to support a weighted accessory. Additionally, or alternatively, it is envisioned that the underwater system400(e.g., the housing402) may include a tether (e.g., a wrist strap) to connect the housing402and the DICD100to the user in the underwater environment.

The housing portion406A includes a pedestal422A supporting a dome424A, and the housing portion406B includes a pedestal422B supporting a dome424B. In certain embodiments of the disclosure, it is envisioned that the housing portions406A,406B may be identical in configuration (e.g., to reduce costs and/or the complexity associated with manufacture and assembly of the housing402).

The domes424A,424B define diameters that lie substantially within the range of approximately 2″ to approximately 8″ (e.g., 4″). During use of the DICD100in underwater environments, however, an increase in the distance between the lenses108A,108B (FIGS.1A,1B) of the DICD100and the water results in a corresponding increase in the quality of the digital data collected by reducing distortion that would otherwise be caused by the water, thus increasing the quality of the images generated by the DICD100(e.g., by stitching together the individual images captured by the image capture devices104A,104B). As such, larger diameter domes424A,424B would not be beyond the scope of the disclosure. The presently disclosed housing402thus functions not only to protect the DICD100, but to increase the quality of the images captured and generated by the DICD100by reducing distortion.

In the illustrated embodiment, the domes424A,424B are generally hemispherical in configuration. In alternate embodiments of the disclosure, however, it is envisioned that the configuration of the domes424A,424B may be varied. For example, the domes424A,424B may be configured as quasi-hemispheres, raised hemispheres including hemispherical and cylindrical portions, shortened hemispheres including a less than 180° portion of a circular arc, or parabolic or other such convex (lens shaped) members.

Although illustrated as being centrically aligned in the embodiment illustrated inFIGS.4and5(i.e., such that an axis XC extending between respective centerpoints CA, CB of the domes424A,424B is oriented in generally parallel relation to the optical axes XA, XB of the lenses108A,108B, respectively, in alternate embodiments of the disclosure, the domes424A,424B may be eccentrically positioned (i.e., the domes424A,424B may be offset such that the axis XC extends transversely in relation to the optical axes XA, XB), as seen inFIG.6.

The housing402is configured such that, upon insertion of the DICD100, the lenses108A,108B of the DICD100are generally aligned with midlines (e.g., equators) of the domes424A,424B, respectively. The lenses108A,108B, however, are laterally offset such that the optical axes XA, XB are misaligned, whereby the optical axes XA, XB are spaced distances DA, DB, respectively, from the axis XC. In various embodiments of the disclosure, it is envisioned that the distances DA, DB may be either equivalent or dissimilar.

To improve operability and/or extend the usable life of the housing402, it is envisioned that the housing402may include one or more internal and/or external coatings (e.g., on inner and/or outer surfaces of the housing portions406A,406B). For example, the housing402may include an anti-fog coating and/or an anti-reflective coating to mitigate glare (e.g., from the various indicators, LEDs, or displays included on the DICD100). It is also envisioned that the housing402may include an anti-scratch coating and/or a hydrophobic coating.

With reference now toFIGS.4,7, and8, the housing402further includes one or more manually-accessible external buttons (actuators)426that are configured in correspondence (e.g., in dimensions and location) with the button(s)116included on the DICD100such that actuation of the external button(s)426causes corresponding actuation of the button(s)116. In the particular embodiment seen inFIGS.4,7, and8, for example, the housing402includes a first external button426A that is configured to actuate the shutter button116A, and a second external button426B that is configured to actuate the mode button116B. It should be appreciated, however, that, in alternate embodiments, the housing402may include additional external buttons426depending on the number of buttons116included on the DICD100.

The external button(s)426are located within the dead zone130(FIGS.2,5) (i.e., outside of the respective fields-of-view106A,106B of the lenses108A,108B) so as not to interfere with image capture. It is envisioned that the external button(s)426may each be included on the same housing portion (e.g., the housing portion406A or the housing portion406B), or, alternatively, that the housing portion406A may include the external button426A and that the housing portion406B may include the external button426B.

It is envisioned that the external button(s)426may be in direct contact with the buttons116on the DICD100such that the user can depress (or otherwise actuate) the buttons116on the DICD100via depression or operation of the external button(s)426. Alternatively, it is envisioned that the external button(s)426may facilitate depression/operation of the buttons116on the DICD via an intervening structure. For example, the external button(s)426may include plungers428(or other such structures) that are movable to depress (or otherwise actuate) the button(s)116. More specifically, with reference toFIG.7, the first external button426A includes a first plunger428A extending along an axis XPA, and the second external button426B includes a second plunger428B extending along an axis XPB. Depending upon the particular location of the buttons116, it is envisioned that the axes XPA, XPB may extend in transverse (e.g., intersecting) relation, as seen inFIG.7.

In various embodiments, it is envisioned that the external button(s)426(e.g., the plunger(s)428) may be in direct alignment with the button(s)116on the DICD100, as shown inFIGS.4,7, and8, or, alternatively, that the external button(s)426(e.g., the plunger(s)428) may be out of direct alignment with the button(s)116on the DICD100. As shown inFIG.8, for example, the plunger(s)428may be operatively connected to an actuation mechanism430that is movable via a rocking motion to actuate the buttons(s)116upon the application of force to the external button(s)426.

As seen inFIG.4, in certain embodiments, the housing402may also include a mount432(e.g., to facilitate use with and/or connection to an accessory, such as a stand or a tripod). The mount432may be movable between a retracted (first) position, in which the mount432is concealed within or by, or is flush with, an outermost external surface of the housing402, and an extended (second) position, in which the mount432is deployed and extends from the housing402(e.g., to facilitate use with the aforementioned accessory). Although the mount432is illustrated as including a series of foldable fingers434(or other such structure(s)) in the particular embodiment seen inFIG.4, it should be appreciated that the configuration of the mount432may be varied in alternate embodiments of the disclosure.

The system400is configured, and the various components thereof are oriented, such that optically clear components, such as the domes424A,424B (FIGS.4,5), are located within the respective fields-of-view106A,106B (FIG.2) of the lenses108A,108B of the DICD100, whereas optically unclear components (i.e., components that are not optically clear or would otherwise interfere with image capture, for example, semi-transparent components, opaque components, etc.), such as the locking member(s)418(FIG.4), the external button(s)426, the mount432, etc., are outside of the fields-of-view106A,106B.

With reference now toFIGS.4,9, and10, the underwater system400may further include a base436that is configured for removable connection to the DICD100when the DICD100is positioned within the housing402. It is envisioned that the base436may include electronics and/or other circuitry to support functionality of the DICD100. For example, the base436may support wireless connectivity of the DICD100to the housing402, as discussed in further detail below, and/or may include a power source (e.g., one or more batteries).

To facilitate connection and disconnection of the DICD100and the base436, the DICD100and the base436may include corresponding engagement structures136,438, respectively. For example, in the embodiment illustrated inFIGS.4,9, and10, the DICD100includes a series of projections138(e.g., fingers) that are configured for receipt within corresponding openings440formed in the base436. It is envisioned that the projections138may be either movably or fixedly connected to the DICD100and that the projections138may be configured to facilitate use with and/or connection to an accessory, such as a stand or a tripod. For example, the projections138may be pivotably connected to the bottom face102F of the body102such that the projections138are repositionable between extended and retracted positions. It is envisioned that the openings440may be configured to receive the projections138in an interference (e.g., snap-fit) arrangement. Additionally, or alternatively, as seen inFIG.10, it is envisioned that the base436may include a locking member442that is configured for engagement with the projections138. More specifically, in the illustrated embodiment, the locking member442includes a key444that is configured for insertion into corresponding apertures140formed in the projections138.

To connect the DICD100to the base436, the locking member442is moved from a locked (first) position, in which the locking member442is positioned within the openings440such that the locking member442is insertable into the apertures140, to an unlocked (second) position, in which the locking member442is withdrawn from the openings440. Once the locking member442is in the unlocked position, the DICD100can be connected to the base436via insertion of the projections138into the openings440, and the locking member442can be moved into the locked position such that the locking member442extends through the apertures140to thereby securely engage the DICD100and the base436. To remove the DICD100from the base436, the locking member442is moved into the unlocked position, during which move, the locking member (e.g., the key444) is withdrawn from the apertures140and the openings440to disengage the locking member442from the DICD. The DICD100can then be separated from the base436by removing the projections138from the openings440.

As illustrated inFIG.10, it is envisioned that the locking member442may include a spring446(or other such biasing member) to bias the locking member442towards the locked position, and a tactile member448(e.g., a handle or ring) to facilitate manual manipulation of the locking member442between the locked and unlocked positions.

FIG.11illustrates a variation on the locking member442(identified by the reference character542), which includes a pair of pins550that are configured for insertion into the apertures140formed in the projections138. In such embodiments, to connect the DICD100to the base436, the pins550are moved from a locked (first) position, in which the pins550are positioned within the openings440in the base436such that the pins550are insertable into the apertures140, to an unlocked (second) position, in which the pins550are withdrawn from the openings440. To guard against inadvertent disconnection of the DICD100from the base436, it may be required to move the pins550in concert from the locked position to the unlocked position. Once the locking member542is in the unlocked position, the DICD100can be connected to the base436insertion of the projections138into the openings440, and the locking member542can be moved into the locked position such that the pins550extend through the apertures140to thereby fixedly secure the DICD100to the base436. As illustrated inFIG.11, it is envisioned that the locking member542may include springs546(or other such biasing members) to bias the pins550towards the locked position. To remove the DICD100from the base436, the locking member542is moved into the unlocked position, during which move, the pins550are withdrawn from the apertures140and the openings440to disengage the locking member542from the DICD. The DICD100can then be separated from the base436by removing the projections138from the openings440.

As mentioned above, it is envisioned that the base436may include electronics (or other such circuitry) that supports wireless connectivity between the DICD100and the base436(e.g., Wi-Fi, Bluetooth, 4G data, and the like). In such embodiments, the sealed, watertight cavity404defined within the housing402allows for wireless communication between the base436and the DICD100such that the base436may be utilized to control operation of the DICD100(e.g., shutter and mode operation), thereby obviating the need for the external buttons426discussed above.

In certain embodiments, it is envisioned that the DICD100and/or the base436may recognize when the DICD100is connected to the base436, and, thus, when the DICD100is positioned within the housing402(e.g., via the incorporation of one or more sensors or other such detection means). In such embodiments, operability of the DICD100may be automatically altered. For example, external lights or indicators may be dimmed or turned off to reduce or eliminate glare and/or reflections off the domes424A,424B. To signal to a user that operation of the DICD100has been altered, it is envisioned that the housing402may include a suitable indicator (e.g., an LED light).

Referring now toFIGS.12and13, to support use with a variety of DICDs (e.g., a DICD100′ having a configuration different from that of the aforementioned DICD100), it is envisioned that the base436may be connectable to an adapter600. For example, the adapter600may be configured to ensure that the DICD100′ is properly positioned within the housing402(FIG.4) so as not to distort (or otherwise compromise) the quality of the images and/or data captured by the DICD100′ (e.g., the adapter600may be configured to support the DICD100′ such that the DICD100′ is properly aligned with the midlines (e.g., equators) of the domes424A,424B in the manner discussed above).

With reference now toFIGS.14-25, alternate configurations for the underwater system400and the housing402will be discussed. The systems and housings discussed below are similar to the aforedescribed underwater system400and housing402, and accordingly, will be discussed only with respect to differences therefrom.

With reference toFIGS.14-16, a system700is illustrated that includes a housing702including discrete first and second housing portions706A,706B, respectively, an internal frame752, and a base736. The frame752is positioned between, and secured to, the housing portions706A,706B. It is envisioned that the frame752and the housing portions706A,706B may be secured together using any method suitable for the intended purpose of creating a watertight connection therebetween, including, for example, the use of an epoxy or ultrasonic welding.

The frame752includes a brace754that supports external buttons726, and a foot section756. In the particular embodiment seen inFIG.14, the brace754supports a first external button726A that is configured in correspondence with the shutter button116A on the DICD100, and a second external button726B that is configured in correspondence with the mode button116B on the DICD100such that the buttons116A,116B can be actuated via the external buttons726A,726B, respectively. The frame752is configured such that the frame752is positioned within the dead zone130(FIG.2) (i.e., outside of the fields-of-view106A,106B of the lenses108A,108B) upon assembly of the system700and the DICD100so as not to interfere with image capture. As seen inFIG.14, the housing portions706A,706B include cutouts758(e.g., recesses) that are configured to accommodate the external buttons726such that the external buttons726are manually accessible by the user.

As seen inFIGS.15and16, in certain embodiments, it is envisioned that the frame752may include a generally I-shaped cross-sectional configuration that includes extensions760defining channels762that are configured to receive the housing portions706A,706B. More specifically, the frame752may define a first channel762A that is configured to receive the housing portion706A, and a second channel762B that is configured to receive the housing portion706B. Upon assembly of the frame752and the housing portions706A,706B, the extensions760are positionable on opposing (internal and external) surfaces of the housing portions706A,706B, as seen inFIG.16.

The foot section756of the frame752defines an opening764(FIG.14) that is configured to allow the DICD100to pass therethrough during loading of the DICD100into the system700. The foot section756intersects the brace754and provides one or more sealing surfaces to mitigate the intrusion of unwanted moisture into the housing402during use of the system700in underwater environments. To enhance sealing between the housing702, the frame752, and/or the base736, it is envisioned that the system700may include one or more sealing members (e.g., rubberized gaskets, O-rings, etc.).

To assemble the system700, it is envisioned that the frame752may be connected to the base736in any suitable manner. For example, the frame752may engage the base736in an interference (e.g., snap-fit) arrangement. Alternatively, it is envisioned that the base736may be pivotably connected to the frame752(e.g., via a hinge or other such structure), and that the base736may be secured in relation to the frame752and the housing702through the use of a clamp, latch, or other such structure.

It is envisioned that the system700may be used in connection with a variety of DICDs100having different configurations. To facilitate such use, the system700may further include the aforementioned adapter600(FIGS.12,13,18) to properly position the DICDs100within the housing702in the manner discussed above. Additionally, it is envisioned that one of the external buttons726(e.g., the external button726B) may include a universal design so as to accommodate for different locations of the buttons116on the DICDs100. For example, as seen inFIGS.17-19, the DICD100may include a button116B positioned in one location (e.g., at a first height) within the housing702(FIG.17), whereas the aforementioned DICD100′ may include a button116B′ positioned in an alternate location (e.g., at a second, different height) within the housing702. To facilitate use with the DICDs100,100′, the external button726B may include the aforedescribed actuation mechanism430such that the plunger428B is positioned to actuate both the button116B on the DICD100and the button116B′ on the DICD100′. More specifically, as seen inFIG.19, the actuation mechanism430may include a plate450with respective first and second toggles452,454that is pivotably connected to the plunger428B such that the plate450can be displaced (e.g., rocked) to cause contact between the toggle452and the button116B on the DICD100and between the toggle454and the button116B′ on the DICD100′ such that the external button726B may be used in connection with either of the DICDs100,100′.

FIG.20illustrates an alternate embodiment of the frame752, which is devoid of the aforedescribed foot section756. In such embodiments, it is envisioned that the brace754and/or the housing702may be directly connected to the base736.

With reference now toFIGS.21-25, another embodiment of the system, which is identified by the reference character800, will be discussed. The system800includes a housing802with a pair of domes824A,824B that are integrally (e.g., monolithically) formed, such as via molding, to define a generally globe-shaped configuration, as well as a base836. The housing802is connected to the base836so as to create a watertight cavity804therebetween. For example, in various embodiments, it is envisioned that the housing802may be inserted into the base836so as to form a seal therebetween, that the base836may be inserted into the housing802so as to form a seal therebetween, or that the housing802and the base836may be configured for rotational engagement via corresponding structures (such as threads) to allow the base836to be rotatably secured to (e.g., screwed onto) the housing802.

With reference toFIGS.22and23, to facilitate the formation of a watertight seal between the housing802and the base836, it is envisioned that the housing802and/or the base836may include one or more sealing members (e.g., gaskets or the like). For example, the base836may include an integral rib866that engages an inner surface of the housing802in a watertight manner. Following connection of the housing802to the base836, it is envisioned that the engagement between the base836and the housing802may be further secured through the use of a clamp, latch, or other such mechanism or structure.

To assemble the DICD100and the system800, it is envisioned that the DICD100may be connected to the base836(in the manner described above), and that the housing802may be lowered onto the base836, as seen inFIG.22. It is also envisioned that the housing802may define an internal compartment868that is configured to receive the DICD100, as seen inFIG.23, and that the base836can be connected to the DICD100after the DICD100is lowered into the housing802(in an inverted orientation).

As discussed above in connection with preceding embodiments, the system800may further include one or more of the aforedescribed adapters600(FIGS.12,13,18) to support use with a variety of DICDs. For example,FIGS.21-24illustrate use of the system800and the DICD100, which is configured for use with the system800without an adapter600.FIG.25, however, illustrates the aforementioned DICD100′, which differs in configuration from the DICD100. To facilitate use of the system800with the DICD100′, the adapter600is positioned between the DICD100′ and the base836such that the DICD100′ is properly positioned within the housing802so as not to distort (or otherwise compromise) the quality of the images and/or data captured by the DICD100′ (e.g., such that the DICD100′ is properly aligned with the midlines (e.g., equators) of the domes824A,824B in the manner discussed above).

With reference now toFIG.26, another embodiment of an underwater system for the DICD100will be discussed, which is identified by the reference character900.FIG.26provides an exploded, perspective view of the underwater system900, which encloses and protects a DICD (e.g., the DICD100) during image/video capture in underwater environments. The underwater system900includes a housing902with respective front (first) and rear (second) housing portions904,906; a center band908that supports the housing portions904,906; a cradle910; and a latching mechanism912. Throughout the discussion that follows, reference will be made to the DICD100. It should be appreciated, however, that the underwater system900may be utilized and adapted for use with any suitable DICD. For example,FIG.27provides a front, plan view illustrating that the underwater system900may include (or may be used with) an adapter914that is configured for reception by (or connection to) the cradle910to allow for use of the underwater system900with a variety of DICDs100having different configurations, profiles, etc.

With reference again toFIG.26, the housing portions904,906collectively create a pressure vessel for the DICD100during underwater image/video capture and collectively define a watertight internal cavity916that receives the DICD100. The housing portions904,906may include (e.g., may be formed partially or entirely from) any material suitable for this intended purpose such as, for example, one or more optically clear plastic materials and may be formed through any suitable manufacturing process (e.g., molding), as discussed above. For example, in one particular embodiment, it is envisioned that the housing portions904,906may include (e.g., may be formed partially or entirely from) polycarbonate. As described in further detail below, the housing portions904,906are configured to allow light to enter the underwater system900in a manner that facilitates proper image/video capture so as to inhibit (if not entirely prevent) underwater distortion during use of the DICD100.

In certain embodiments, such as that shown throughout the figures, the housing portions904,906may be identical in configuration. More specifically, the housing portions904,906respectively include domes918,920and generally planar extensions922,924that extend from the domes918,920so as to conceal and protect the cradle910, the latching mechanism912, etc. To reduce (if not entirely prevent) the entry of water and potential leakage paths during underwater use, the housing portions904,906may be unitarily (e.g., monolithically formed) such that the domes918,920are integrally connected to the respective planar extensions922,924.

As seen inFIG.28, which provides a side, plan view of the underwater system900and the DICD100, the domes918,920define respective fields-of-view926,928each of which spans at least 180° to allow the images/video captured by the DICD100(e.g., by the lenses108A,108B) to be stitched together. In underwater environments, however, light entering the underwater system900is refracted as it transitions from the water to the domes918,920to the air retained within the internal cavity916defined by the domes918,920, which effectively reduces the fields-of-view926,928. To compensate for such refraction, it is envisioned that the respective fields-of-view926,928defined by the domes918,920may be extended beyond 180° to increases the overlap to more than 360°. For example, in the illustrated embodiment, the dome918includes opposite ends930i,930iithat are laterally separated from corresponding opposite ends932i,932iiof the dome920by the center band908such that the ends930i,930ii,932i,932iiof the domes918,920are laterally offset from (i.e., positioned outwardly of) a geometrical midpoint M of the DICD100. In the particular embodiment shown throughout the figures, for example, the underwater system900is configured such that the ends930i,930iiof the dome918are laterally separated from the ends932i,932iiof the dome920by approximately 24 mm. The lateral separation created by the center band908allows for less offset between the ends930i,930iiof the dome918and the lens108A and between the ends932i,932iiof the dome920and the lens108B and attributes a generally spherocylindrical profile (e.g., an “egg” or “pill” shaped configuration) to the portion of the housing902including the domes918,920and the section of the center band908therebetween. This geometry individually optimizes the optics of the domes918,920relative to the lenses108A,108B, respectively, to thereby reduce bending in any incoming light, which allows the respective fields-of-view926,928defined by the domes918,920to span more than 180°. In the illustrated embodiment, for example, the geometry of the domes918,920allows the respective fields-of-view926,928to span approximately 188°. It should be appreciated, however, that both larger and smaller fields-of-view926,928are contemplated herein which may be realized by varying the particular geometries of the domes918,920and the center band908and/or the specific mounting locations of the dome domes918,920to the center band908.

Referring now toFIGS.26and29A-30B, the center band908includes respective front (first) and rear (second) support bands934,936.FIGS.29A and29Bprovide front and rear perspective views of the support band934, respectively, andFIGS.30A and30Bprovide front and rear perspective views of the support band936, respectively. The support bands934,936provide mounting locations for the domes918,920and may include (e.g., may be formed partially or entirely from) any material suitable for this intended purpose, such as, for example, one or more plastic materials. The support bands934,936are pivotally connected via a hinge pin938(FIG.26), whereby the underwater system900is repositionable between open and closed positions, as described in further detail below.

The front support band934includes an upper, arcuate section940that is configured in correspondence with the918,920of the housing portions904,906and a lower, planar section942that extends from the upper section940and is configured in correspondence with the extensions922,924of the housing portions904,906, respectively. The upper section940includes a series of mounts944and a series of receptacles946, and the lower section942includes a mounting member948. In certain embodiments, such as that illustrated throughout the figures, it is envisioned that the front support band934may be unitarily (e.g., monolithically) formed, whereby the mounts944and the receptacles946may be integrally formed with the upper section940and the mounting member948may be integrally formed with the lower section942.

The mounts944are configured to support the connection of one or more latches950to allow for movement of the latches950(FIG.26) between open (unlocked) and closed (locked) positions and, thus, repositioning of the underwater system900between the open and closed positions. In the illustrated embodiment, for example, each of the mounts944is configured to receive a wireform952that pivotally connects the latches950to the mounts944. As seen inFIG.31, which provides a horizontal, cross-sectional view of the underwater system900and the DICD100, so as not to interfere with image/video capture, the mounts944and the latches950may be oriented within the blind spots126,128, outside of the fields-of-view106A,106B of the lenses108A,108B, within the “dead zone”130. Although shown as including three mounts944and three latches950in the illustrated embodiment (e.g., a top latch950tand a pair of side latches950si,950sii), it should be appreciated that the particular number and/or orientation of the mounts944and the latches950may be varied without departing from the scope of the present disclosure. As such, embodiments including both greater and fewer numbers of mounts944and latches950are contemplated herein.

The receptacles946included on the front support band934are configured to receive (or otherwise accommodate) one or more actuation mechanisms954(FIG.26), which facilitate the operation of various features on the DICD100. For example, in the particular embodiment illustrated throughout the figures, the front support band934includes a first receptacle946ithat is configured to receive (or otherwise accommodate) a first actuation mechanism954ithat is configured to facilitate operation of the shutter button116A (FIG.1A) on the DICD100and a second receptacle946iithat is configured to receive (or otherwise accommodate) a second actuation mechanism954iithat is configured to facilitate operation of the mode button116B (FIG.1A) on the DICD100, as described in further detail below.

The mounting member948(FIGS.29A,29B) includes a plurality of fingers956and is configured to facilitate use of the underwater system900with (and/or connection to) an accessory, such as a stand or a tripod. Additionally, the mounting member948is configured for engagement (contact) with the rear support band936during movement of the underwater system900from the closed position to the open position to define a range of (pivotable) movement for the underwater system900. In the illustrated embodiment, for example, the mounting member948is configured to restrict the range of movement of the underwater system900to approximately 60°. It should be appreciated, however, that the configuration of the mounting member948may be altered in various embodiments of the disclosure to adjust the range of movement of the underwater system900as necessary or desired. Thus, ranges of movement larger and smaller than 60° are also contemplated herein.

The rear support band936includes an upper, arcuate section958that is configured in correspondence with the domes918,920(FIG.26) of the housing portions904,906and a lower, planar section960that extends from the upper section958and is configured in correspondence with the extensions922,924of the housing portions904,906, respectively. The upper section958includes a series of clasps962and the lower section960includes a platform964that is configured to support the cradle910. In certain embodiments, such as that illustrated throughout the figures, it is envisioned that the rear support band936may be unitarily (e.g., monolithically) formed, whereby the clasps962may be integrally formed with the upper section958and the platform964may be integrally formed with the lower section960.

The clasps962each include an engagement member966(FIG.30A) that is configured for mating contact with the latches950to allow for connection and disconnection of the latches950and the clasps962during movement of the latches950between the open (unlocked) and closed (locked) positions, and, thus, repositioning of the underwater system900between the open and closed positions. So as not to interfere with image/video capture, in certain embodiments, such as that illustrated inFIGS.26-31, as discussed with respect to the mounts944and the latches950, the clasps962may be oriented within the blind spots126,128(FIG.31), outside of the fields-of-view106A,106B of the lenses108A,108B, within the “dead zone”130.

With reference toFIG.32, which provides a top, perspective view of the cradle910and the platform964, to facilitate proper connection and orientation of the cradle910with respect to the rear support band936, the platform964includes one or more alignment features968that are configured for receipt within corresponding slots970(or other such openings) in the cradle910. More specifically, in the illustrated embodiment, the platform964includes a pair of alignment features968i,968iipositioned on opposite sides of the platform964that are configured for insertion as upstanding (vertical) ribs972. It should be appreciated, however, that the particular configuration of the alignment features968may be varied in alternate embodiments without departing from the scope of the present disclosure.

As seen inFIG.32, the platform964further includes one or more bosses974and a receptacle976that defines one or more (vertical) openings978(e.g., slots980) and (transverse) apertures982that extend in generally orthogonal relation to the openings978. The boss(es)974are configured to receive one or more corresponding fasteners984(FIG.26) (e.g., screws, pins, rivets, or the like) that extend through corresponding openings986in the cradle910to secure the cradle910to the platform964. The opening(s)978in the receptacle976are positioned in alignment with one or more opening(s)988(e.g., slots990) in the cradle910to accommodate and receive the engagement structure136(FIGS.10,11) on the DICD100(e.g., the projections138). In such embodiments, the projections138may be inserted through the opening(s)988in the cradle910and into the opening(s)978in the receptacle976on the platform964to facilitate proper seating of the DICD100within the cradle910and reception of the DICD100by the underwater system900. As described in further detail below, the aperture(s)982in the receptacle976are configured to receive and accommodate movement of the latching mechanism912during movement between locked and unlocked positions, as described in further detail below.

As mentioned above, the respective front and rear support bands934,936are pivotally connected to one another to allow for repositioning of the underwater system900between the open and closed positions, as seen inFIGS.33and34, respectively, which provides side, plan views of the underwater system900. To facilitate such movement, the respective front and rear support bands934,936include a series of corresponding hinge members992that are configured to receive the aforementioned hinge pin938.

To maintain the integrity of the watertight internal cavity916defined by the housing portions904,906, the underwater system900includes a series of sealed (or sealable) connections between the housing portions904,906and the center band908(i.e., the respective front and rear support bands934,936). For example, as seen inFIG.35, which provides a partial, cross-sectional view of the underwater system900taken through one of the latches950, in the particular embodiment of the disclosure illustrated throughout the figures, the underwater system900includes adhesive joints994to fixedly and sealingly connect the housing portion904to the front support band934and the housing portion906to the rear support band936as well as one or more sealing members996(e.g., gaskets998) to establish and maintain a watertight seal between the support bands934,936. It is envisioned that the sealing member(s)996may include (e.g., may be formed partially or entirely from) a compressible material, such as, for example, an elastomeric material, to facilitate radial (outward) expansion of the sealing member(s)996upon movement of the underwater system900into the closed position (e.g., upon locking of the latches950).

With reference now toFIGS.26and32, the cradle910will be discussed. The cradle910is configured to support the DICD100within the underwater system900and may include (e.g., may be formed from) any suitable material or combination of materials. To facilitate reception of the DICD100, the cradle910includes a body portion1000defining opposite first and second ends1002,1004, respectively, and a seat1006that is configured in correspondence with the body102of the DICD100.

In certain embodiments, the underwater system900may include one or more dampeners1008(e.g., bumpers, cushions, or the like) to facilitate proper location of the DICD100within the underwater system900and further stabilize the DICD100to reduce (if not entirely eliminate) undesirable movement of the DICD100within the underwater system900. In the particular embodiment illustrated throughout the figures, for example, the underwater system900includes one more first dampeners1008ithat are positioned adjacent to the seat1006defined by the cradle910(e.g., to vertically stabilize the DICD100) and one or more second dampeners1008iithat are positioned adjacent to inner surfaces of the housing portions904,906for contact with the faces102A,102B (FIG.1A) of the DICD100(e.g., to laterally stabilize the DICD100).

The cradle910is fixedly connected to the rear support936(e.g., to the platform964) via the fasteners984. In certain embodiments, to increase clearance of the latches950with respect to the fields-of-view106A,106B (FIG.31) of the lenses108A,108B, the seat1006of the cradle910may be positioned eccentrically relative to the body portion1000and the center band908. More specifically, as seen inFIG.36, which provides a top, perspective view of the cradle910, the cradle910may be configured such that a midline MS (shown in a dashed line) extending through the seat1006is angularly offset from a midline M (shown in a solid line) extending through the body portion1000of the cradle910and the center band908by an angle α. In the particular embodiment illustrated, the cradle910is configured such that the angle α is approximately 1°. It should be appreciated, however, that the configuration of the cradle910may be varied in alternate embodiments to increase or decrease the angle α as necessary or desired (e.g., based upon the particular dimensions of the DICD100, the latches950, etc.). As seen inFIG.36, the angular offset of the seat1006may be achieved by varying the thickness T of respective front and rear walls1010,1012of the cradle910. To further accommodate the eccentric orientation of the seat1006and, thus, the eccentric orientation of the DICD100within the underwater system900, it is envisioned that the thicknesses of the extensions922,924(FIG.26) of the housing portions904,906may also be varied, whereby the thickness at one lateral end of the extensions922,924may exceed the thickness as an opposing lateral end of the extensions922,924(e.g., by approximately 1 mm).

In an alternate embodiment, it is envisioned that the aforedescribed angular offset of the seat1006and the DICD100may be achieved by varying the orientation of the cradle910itself. More specifically, it is envisioned that the cradle910may be angularly offset from the midline M by the angle α such that the midlines M, MS are colinear and each extend through the body portion1000of the cradle and the seat1006, thereby obviating the need to vary the thickness T of the respective front and rear walls1010,1012of the cradle910.

With reference now toFIGS.26and37-39B, the latching mechanism912will be discussed. More specifically,FIG.37provides a perspective view of the latching mechanism912;FIG.38provides an exploded, perspective view of rear support band936illustrating positioning of the latching mechanism912between the cradle910and the platform964;FIG.39Aprovides a rear, perspective view of the rear support band936illustrating the latching mechanism912in the locked position; andFIG.39Bprovides a rear, perspective view of the rear support band936illustrating the latching mechanism912in the unlocked position.

The latching mechanism912is received in an undercut1014(e.g., a recess, a chamber, etc.) defined by the body portion1000of the cradle910and includes opposite first and second ends1016,1018, respectively, as well as a locking pin1020and a stop1022that define a gap1024therebetween. The locking pin1020is configured for insertion into and removal from the transverse aperture(s)982(FIG.32) in the receptacle976of the platform964during movement of the latching mechanism912between the locked position (FIG.39A) and the unlocked position (FIG.39B). More specifically, when the latching mechanism912is in the locked position, the ends1016,1018of the latching mechanism912are generally aligned with the ends1002,1004of the cradle910, respectively, and the locking pin1020extends through the transverse aperture(s)982and the apertures140(FIGS.10,11) formed in the engagement structure136on the DICD100to thereby securely connect the DICD100to the underwater system900. When removal of the DICD100from the underwater system900is necessary or desired, the latching mechanism912can be moved in to the unlocked position via lateral movement (sliding) relative to the cradle910and the platform964, whereby the locking pin1020is removed from the transverse aperture(s)982and from the engagement structure136on the DICD100. In the unlocked position, the gap1024defined between the locking pin1020and the stop1022is generally aligned with the receptacle976and the opening(s)988in the cradle910, which allows the engagement structure136on the DICD100to be removed from the receptacle976, from the latching mechanism912via the gap1024, and from the cradle910, thus allowing for separation of the DICD100from the underwater system900. As seen inFIG.39B, in the unlocked position, the latching mechanism912is laterally offset from the cradle910such that the ends1016,1018of the latching mechanism912are spaced laterally (horizontally) from the ends1002,1004of the cradle910, respectively. When so positioned, the latching mechanism912extends laterally outward from the cradle910such that the end1016of the latching mechanism912is positioned between the support bands934,936to interfere with (inhibit, block) closure of the underwater system900, thereby preventing use of the underwater system900until the DICD100is secured in place via the latching mechanism912. In certain embodiments, it is envisioned that the end1016of the latching mechanism912may include a visual indicator1026(FIG.37) (e.g., color variation, different texturing, etc.) to identify the latching mechanism912as being in the unlocked position.

The range of motion for the latching mechanism912is defined by the stop1022, which is configured for engagement (contact) with corresponding structure on the cradle910. More specifically, during movement of the latching mechanism912from the locked position to the unlocked position, the stop1022is brought into engagement (contact) with a wall of the cradle910to thereby restrict continued movement of the latching mechanism912and maintain the assembly of the platform964, the latching mechanism912, and the cradle910.

Although shown as being unitarily (e.g., monolithically) formed inFIGS.26and37-39B(for example), in alternate embodiments of the disclosure, it is envisioned that the latching mechanism912may include a multi-piece construction. For example,FIG.40provides a top, perspective view of an alternate embodiment of the latching mechanism, which is identified by the reference character1028shown with parts separated, andFIG.41provides a top, perspective view of the latching mechanism1028upon assembly. The latching mechanism1028includes respective first and second body portions1030,1032that are configured for releasable connection (e.g., in a snap-fit arrangement). The first body portion1030includes the aforedescribed stop1022and defines a receiving space1034that is configured to receive the second body portion1032. The second body portion1032includes the aforedescribed locking pin1020and is positionable within the receiving space1034defined by the first body portion1030such that the aforedescribed gap1024is defined between the locking pin1020and the stop1022to support functionality in the manner discussed above. To facilitate connection of the respective first and second body portions1030,1032, it is envisioned that the second body portion1032may include an undercut (or other such recess or opening) that is configured to receive the first body portion1030. In the illustrated embodiment, the aforementioned visual indicator1026is included on the second body portion1032, which may include coloration or texturing that differs from that of the first body portion1030.

With reference now toFIGS.42-45, use and operation of the actuation mechanisms954i,954iiin connection with operation of the shutter button116A and the mode button116B on the DICD100. More specifically,FIG.42provides a (vertical) cross-sectional view of the actuation mechanism954iprior to closure of the underwater system900and shown in an inactive position;FIG.43provides a (vertical) cross-sectional view of the actuation mechanism954iupon closure of the underwater system900and shown in an intermediate (pre-loaded) position;FIG.44provides a (vertical) cross-sectional view of the actuation mechanism954iupon closure of the underwater system900and shown in an active position; andFIG.45provides a (vertical) cross-sectional view of the actuation mechanism954iishown in an inactive position.

As mentioned above, the actuation mechanism954iis accommodated within the receptacle946iof the front support band934. The actuation mechanism954iincludes an actuator1036; a post1038that is operatively connected to the actuator1036(e.g., via a threaded connection); and a biasing member1040(e.g., a spring1042).

The actuator1036includes a body portion1044defining outer (bearing) surface1046that is configured for engagement (contact) with a depressible actuation button1048included in the top latch950t. The body portion1044includes a threaded aperture1050that is configured to receive a threaded end1052of the post1038to secure the post1038to the actuator1036such that linear (e.g., vertical) movement of the actuator1036causes corresponding linear (e.g., vertical) movement of the post1038. To stabilize the actuator1036relative to the front support band934, in certain embodiments, such as that shown throughout the figures, the actuator1036may include a leg1054that is configured for receipt within a corresponding opening1056defined in the receptacle946ito reduce (if not entirely eliminate) undesirable movement (e.g., rocking, wobbling, etc.) of the actuator1036.

The post1038is received within a channel1058defined by the receptacle946iand is elongate (e.g., generally tubular) in configuration. The post1038includes a foot1060that is positioned opposite to the threaded end1052of the post1038. The foot1060defines a transverse cross-sectional dimension (e.g., a width) greater than that defined by an end of the channel1058to prevent inadvertent removal (withdrawal) of the post1038from the channel1058. To guard against water intrusion, in certain embodiments, such as that seen inFIGS.42-44, the actuation mechanism954imay include a sealing member1062(e.g., a washer, an O-ring, etc.) that is positioned about the post1038to inhibit (if not entirely prevent) the entry of water into the underwater system900through the actuation mechanism954iand the receptacle946i(e.g., via the channel1058).

When the underwater system900is in the open position, the actuation mechanism954iis in the inactive (extended) position (FIG.42), in which, the post1038is spaced axially from the shutter button116A by a distance D1, which provides sufficient clearance for insertion of the DICD100into the underwater system900and positioning of the shutter button116A beneath the post1038. Subsequent to closure of the underwater system900, upon depression of the actuation button1048in the top latch950t, the actuation mechanism954iis moved from the inactive position into the active (depressed) position (FIG.44), during which, the post1038is brought into engagement (contact) with the shutter button116A via (vertical) depression of the actuator1036to operate the shutter button116A. The biasing member1040is positioned about the post1038within the receptacle946iso as to bias the actuation mechanism954itowards the inactive position. Upon the application of sufficient force to the actuation button1048, the bias applied by the biasing member1040is overcome and the actuation mechanism954iis moved into the active position. Upon release of the actuation button1048, the biasing member1040returns the actuation mechanism954ito the inactive position via outward (vertical) movement of the actuator1036, which is limited via contact between the foot1060and the end of the channel1058and via contact between the actuator1036and the actuation button1048. To restrict outward (vertical) movement of the actuation button1048and resist force applied by the biasing member1040, in certain embodiments, the actuation button1048may define a flange1064(FIG.43) that is received beneath a shoulder1066defined by the top latch950t.

As seen inFIGS.43and44, in certain embodiment, the top latch950tmay include a detent1068(FIG.43) that extends inwardly towards the actuator1036. The detent1068is configured for engagement (contact) with the actuator1036during closure of the top latch950tso as to pre-load the actuation mechanism954ivia movement to an intermediate (partially depressed) position, seen inFIG.43, between the inactive position (FIG.42) and the active position (FIG.44). More specifically, as the top latch950tis closed, the detent1068is brought into engagement (contact) with the bearing surface1046of the actuator1036to partially depress the actuator1036and, thus, the post1038, to reduce the distance D1. By pre-loading the actuation mechanism954i, the overall amount of travel required to actuate the shutter button116A can be reduced. In such embodiments, the actuation mechanism954iis thus movable between three discrete positions: the inactive position (FIG.42); the intermediate (pre-loaded) position (FIG.43); and the active position (FIG.44).

With reference now toFIG.45, the actuation mechanism954iiwill be discussed, which, as indicated above, is accommodated within the receptacle946iiof the front support band934i. The actuation mechanism954iiincludes an actuator1070; a retainer1072(e.g., an E-clip1074); and a biasing member1076(e.g., a spring1078).

The actuator1070includes a first leg1080that is configured for engagement (contact) with the mode button116B such that linear (e.g., horizontal) movement of the actuator1070causes corresponding linear (e.g., horizontal) movement of the mode button116B. As seen inFIG.45, in certain embodiments, the first leg1080may be eccentrically positioned, which allows the actuation mechanism954iito be (vertically) offset from the mode button116B so as to increase clearance with the side latch950si(FIG.26). In such embodiments, to stabilize the actuator1070relative to the front support band934, the actuator1070may further include a second leg1082that is configured for receipt within a corresponding opening1084defined in the receptacle946iito reduce (if not entirely eliminate) undesirable movement (e.g., rocking, wobbling, etc.) of the actuator1070.

To guard against water intrusion, in certain embodiments, such as that seen inFIG.45, the actuation mechanism954iimay include a sealing member1086(e.g., a washer, an O-ring, etc.) that is positioned about the first leg1080to inhibit (if not entirely prevent) the entry of water into the underwater system900through the actuation mechanism954ii. To maintain assembly and positioning of the sealing member1086, it is envisioned that the sealing member1086may be retained in place by a cap1088that is secured with the receptacle946ii.

The retainer1072is fixedly connected to the first leg1080of the actuator1070such that movement of the actuator1070causes corresponding movement of the retainer1072. For example, in the illustrated embodiment, the retainer1072is received within a corresponding (annular) channel1090formed in the first leg1080. The retainer1072extends outwardly from the first leg1080and is configured for engagement with a stop1092defined by the receptacle946iiso as to limit outward linear (e.g., horizontal) travel of the actuator1070away from the DICD100to thereby maintain assembly of the actuation mechanism954iiwithin the receptacle946iiand limit the range of motion of the actuation mechanism954ii, as described in further detail below.

The actuation mechanism954iiis movable between an inactive (extended) position (FIG.45) and an active (depressed) position via the application of force to the actuator1070through the receptacle946ii. In the inactive position, the first leg1080is spaced axially from the mode button116B, which provides sufficient clearance for insertion of the DICD100into the underwater system900and positioning of the mode button116B inwardly of the first leg1080. In the active position, the first leg1080is brought into engagement (contact) with the mode button116B to control operation thereof by depression of the actuator1070. As seen inFIG.45, the biasing member1076is positioned in engagement (contact) with the receptacle946iiso as to bias the actuation mechanism954iitowards the inactive position. More specifically, in the illustrated embodiment, the biasing member1076is positioned about the second leg1082. Upon the application of sufficient force to the actuator1070, the biasing force applied by the biasing member1076is overcome and the actuation mechanism954iiis moved into the active position, whereby the retainer1072is moved inwardly and separated from the stop1092. Upon release of the actuator1070, the biasing member1076returns the actuation mechanism954iito the inactive position via outward movement of the actuator1070, which is limited via contact between the retainer1072and the stop1092.

FIG.46illustrates an alternate embodiment of the actuation mechanism954ii, which is identified by the reference character1094ii. The actuation mechanism1094iiis substantially similar to the actuation mechanism954iiand, accordingly, will only be discussed with respect to any differences therefrom in the interest of brevity. The actuation mechanism1094iiincludes an actuator1096; a trigger1098that is operatively connected to the actuator1096, the aforedescribed retainer1072; and a biasing member1100(e.g., a spring1102).

The actuator1096includes a leg1104that extends into (and is secured within) an opening1106defined by the trigger1098so as to operatively connect the actuator1096and the trigger1098such that such that linear (e.g., horizontal) movement of the actuator1096causes corresponding linear (e.g., horizontal) movement of the trigger1098and, thus, the mode button116B. It is envisioned that the actuator1096and the trigger1098may be connected in any manner suitable for the intended purpose of facilitating such corresponding movement. For example, it is envisioned that the leg1104may be received by the opening1106in the trigger1098in an interference fit, that the leg1104may me adhesively and/or mechanically connected to the trigger1098(e.g., via a set screw or other such fastener), or that the actuator1096and the trigger1098may be unitarily (e.g., monolithically) formed. As seen inFIG.46, the leg1104is centrally positioned within the receptacle946ii, but is (vertically) offset from the mode button116B. The leg1104supports the retainer1072such that movement of the actuator1096causes corresponding movement of the retainer1072, as discussed in connection with the aforedescribed actuation mechanism954ii.

To guard against water intrusion, in certain embodiments, such as that seen inFIG.46, the actuation mechanism1094iimay include a sealing member1108(e.g., a washer, an O-ring, etc.) that is positioned about the leg1104of the actuator1096to inhibit (if not entirely prevent) the entry of water into the underwater system900through the actuation mechanism1094ii. To maintain assembly and positioning of the sealing member1108, it is envisioned that the sealing member1108may be retained in place by a cap1110that is secured with the receptacle946ii.

The leg1112of the trigger1098is offset from (eccentrically positioned relative to) both the opening1106and the receptacle946ii, which allows the actuation mechanism1094iito be (vertically) offset from the mode button116B so as to increase clearance with the side latch950si(FIG.26). In certain embodiments, such as that seen inFIG.46, for example, to stabilize the trigger1098relative to the front support band934, the trigger1098may define a recess1114that is configured to receive a corresponding detent1116defined by the front support band934within the receptacle946ii. Reception of the detent1116by the recess1114reduces (if not entirely eliminates) undesirable movement (e.g., rocking, wobbling, etc.) of the trigger1098.

The actuation mechanism1094iiis movable between an inactive (extended) position (FIG.46) and an active (depressed) position via the application of force to the actuator1096. In the inactive position, the leg1112of the trigger1098is spaced axially from the mode button116B, which provides sufficient clearance for insertion of the DICD100into the underwater system900and positioning of the mode button116B inwardly of the trigger1098. In the active position, the leg1112of the trigger1098is brought into engagement (contact) with the mode button116B to control operation thereof by depression of the actuator1096. As seen inFIG.46, the biasing member1100is positioned in engagement (contact) with the receptacle946iiso as to bias the actuation mechanism1094iitowards the inactive position. More specifically, in the illustrated embodiment, the biasing member1100is positioned about the leg1104of the actuator1096.

Referring now toFIGS.47and48, an alternate embodiment of the underwater system will be described, which is identified by the reference character1200. More specifically,FIG.47provides an exploded, perspective view of the underwater system1200andFIG.48provides a partial, (vertical) cross-sectional view of the underwater system1200shown with the DICD100. The underwater system1200is substantially similar to the aforedescribed underwater system900and, accordingly, will only be discussed with respect to any differences therefrom in the interest of brevity. Throughout the discussion that follows, reference will again be made to the DICD100. It should be appreciated, however, that the underwater system1200may be utilized and adapted for use with any suitable DICD.

The underwater system1200includes a front support band1202that is connected to the housing portion904; a rear support band1204that is connected to the housing portion906; a cradle1206that is received within a cavity1208defined by the rear support band1204; and a latching mechanism1210. Throughout the discussion that follows, reference will again be made to the DICD100. It should be appreciated, however, that the underwater system1200may be utilized and adapted for use with any suitable DICD.

The cradle1206includes an upper body portion1212defining a seat1214for the DICD100and a lower body portion1216defining a pair of lateral cutouts1218,1220that are configured to accommodate lateral (sliding) movement of the latching mechanism1210. The cradle1206defines one or more opening(s)1222(e.g., slots1224) that are configured to receive the engagement structure136on the DICD100as well as one or more (transverse) apertures1226that extend in generally orthogonal relation to the openings1222. As discussed in connection with the underwater system900, the aperture(s)1226are configured to receive and accommodate movement of the latching mechanism1210during locking and unlocking thereof.

The latching mechanism1210includes a pair of opposing lateral members1228,1230that are configured for reception (and movement) within the cutouts1218,1220defined by the lower body portion1216of the cradle1206, respectively, as well as a locking member1232that extends between the lateral members1228,1230. In the illustrated embodiment, the lateral members1228,1230and the locking member1232are illustrated as discrete structures. It should be appreciated, however, that the latching mechanism1210may be unitarily (e.g., monolithically) formed in alternate embodiments of the disclosure such that the lateral members1228,1230and the locking member1232are integrally connected.

The locking member1232includes a body1234with pair of struts1236,1238that are connected by a transverse crossbar1240that extends between the struts1236,1238from end portions thereof such that the body1234includes a generally U-shaped configuration. The locking member1232further includes a locking pin1242that extends from the strut1236towards the strut1238in generally parallel relation to the crossbar1240. The struts1236,1238, the crossbar1240, and the locking pin1242are unitarily (e.g., monolithically) formed and may be manufactured using any suitable method. Embodiments in which one or more of the struts1236,1238, the crossbar1240, and the locking pin1242are formed as separate, discrete components, however, would not be beyond the scope of the present disclosure.

The locking pin1242is configured for insertion into and removal from the aperture(s)1226in the cradle1206and the apertures140(FIG.48) formed in the engagement structure136on the DICD100during movement of the locking member1232between locked and unlocked positions to thereby securely connect the DICD100to the cradle1206and, thus, the underwater system1200. The locking pin1242defines a gap1244with the strut1238that is configured in correspondence with the engagement structure136on the DICD100to allow for separation of the DICD100from the locking member1232and the cradle1206when the locking member1232is in the unlocked position.

Referring now toFIGS.49and50, an alternate embodiment of the underwater system will be described, which is identified by the reference character1300. More specifically,FIG.49provides an exploded, perspective view of the underwater system1300andFIG.50provides a partial, rear, perspective view of the underwater system1300shown with the DICD100. The underwater system1300is substantially similar to the aforedescribed underwater systems900,1200and, accordingly, will only be discussed with respect to any differences therefrom in the interest of brevity. Throughout the discussion that follows, reference will again be made to the DICD100. It should be appreciated, however, that the underwater system1300may be utilized and adapted for use with any suitable DICD.

The underwater system1300includes respective front and rear housing portions1302,1304and a center support band1306that is connected to the housing portions1302,1304. In contrast to the underwater system900, the housing portions1302,1304include dissimilar configurations. More specifically, the front housing portion1302includes a dome1308and a generally planar extension1310that extends from the dome1308and the rear housing portion1304includes a dome1312; a generally planar extension1314that extends from the dome1312; and a cradle1316.

The housing portions1302,1304are pivotably connected via a hinge mechanism1318in a clamshell-style arrangement such that the housing portions1302,1304are relatively moveable (pivotable) during opening and closure of the underwater system1300. Whereas the front housing portion1302is fixedly connected to the support band1306, the rear housing portion1304is movable relative to the support band1306via the hinge mechanism1318. To reduce (if not entirely prevent) the entry of water and potential leakage paths during underwater use, the underwater system1300includes one or more sealing members1320(e.g., gaskets1322) that are positioned between, and configured in correspondence with, the rear housing portion1304and the support band1306.

The cradle1316is formed integrally (e.g., monolithically) with the rear housing portion1304adjacent to the planar extension1314and defines a seat1324that is configured to accommodate the DICD100. The cradle1316defines one or more internal chambers (cavities)1326arranged below the seat1324that are configured to receive a locking mechanism1328(FIG.51), which is described below, as well as one or more opening(s)1330(e.g., slots1332) that are configured to receive the corresponding engagement structure136on the DICD100.

Referring now toFIG.51as well, which provides a partial, plan view of the rear housing portion1304, the locking mechanism1328includes one or more buttons1334that are connected to one or more locking members1336such that inward displacement (sliding movement) of the button(s)1334causes corresponding movement of the locking member(s)1336. Although shown as including a pair of buttons1334i,1334iithat are respectively connected to a pair of locking members1336i,1336iiinFIG.51, in alternate embodiments of the disclosure, it is envisioned that the underwater system1300may instead include a single button1334and a single locking member1336.

The buttons1334and the locking members1336are accommodated by the internal chambers1326defined by the cradle1316. Each of the locking members1336includes a first end1338that is fixedly connected to a corresponding button1334and a (free) second end1340that is configured for releasable engagement (contact) with the engagement structure136on the DICD100during locking and unlocking of the locking mechanism1328. More specifically, via movement of the buttons1334, the locking members1336are movable between a locked (first) position (FIG.51), in which the locking members1336extends through the apertures140formed in the engagement structure136on the DICD100to thereby securely connect the DICD100to the underwater system1300, and a unlocked (second) position, in which the locking members1336are separated from the engagement structure136on the DICD100to allow for separation of the DICD100from the cradle1316and removal of the DICD100from the underwater system1300. In certain embodiments, it is envisioned that the locking mechanism1328may include a biasing member (not shown) (e.g., a spring) that is configured to bias the locking mechanism1328towards the locked position.

In the illustrated embodiment, the locking mechanism1328is configured such that the locking members1336are disengaged from the engagement structure136on the DICD100upon inwardly displacement of the buttons1334and movement of the locking members1336towards each other. To facilitate such operation, the locking members1336each include a generally J-shaped configuration, as seen inFIG.51.

To protect the locking mechanism1328and inhibit the collection of dust, debris, etc., in certain embodiments, the underwater system1300may include a cover plate1342(FIGS.49,50) that is configured for connection to the cradle1316to conceal the locking mechanism1328. It is envisioned that the cover plate1342and the cradle1316may be configured for releasable connection to allow for cleaning, component repair and/or replacement, etc.
