DETAILED DESCRIPTION

[0034] In general, the terms and phrases used herein have their art-recognized meaning, which can be found by reference to standard texts, journal references and contexts known to those skilled in the art. The following definitions are provided to clarify their specific use in the context of this description.

[0035] A “device” is a combination of components operably connected to produce one or more desired functions.

[0036] A “component” is used broadly to refer to an individual part of a device.

[0037] “Proximal” and “distal” refer to the relative positions of two or more objects, planes or surfaces. For example, an object that is close in space to a reference point relative to the position of another object is considered proximal to the reference point, whereas an object that is further away in space from a reference point relative to the position of another object is considered distal to the reference point.

[0038] The terms “direct and indirect” describe the actions or physical positions of one object relative to another object. For example, an object that “directly” acts upon or touches another object does so without intervention from an intermediary. Contrarily, an object that “indirectly” acts upon or touches another object does so through an intermediary (e.g., a third component).

[0039] FIG. 1 is a photograph of a light source comprising a male connector configured to thread into a light bulb socket, a body extending from the male connector that emits electromagnetic radiation in a 360 degree cylindrical pattern, and a mounting device, shown as a threaded rod, at an opposite end of the body from the male connector. In FIG. 1, the body of the light source comprises a plurality of light emitting diodes (LEDs) that emit electromagnetic radiation (EMR), which is directed outward in a 360 degree cylindrical pattern by one or more reflectors. Alternatively, EMR may be emitted from a fluorescent or halogen bulb. As shown, a blackout disk is disposed between the body of the light source and the mounting device. The blackout disk prevents flares from appearing in images, due to light reflecting from a non-absorbitive (e.g., bright or white) surface, when a camera attached to the mounting device has a very wide field-of-view (e.g., a 3D camera or video recorder).

[0040] FIG. 2 is a photograph showing a side view of the light source of FIG. 1 attached to a distal end of a device for capturing virtual tour data, according to an embodiment. The male connector of the light source is threaded into a custom end piece comprising a light bulb socket and a pivot joint. In the embodiment shown, a cable is configured for connection to a camera (not shown) that will be attached to the mounting device. The cable is routed through the device and operably connected to an external hard drive, which may for example be housed in a mobile device (see, e.g., FIG. 10). In other embodiments, a camera may contain local data storage (e.g., a memory card of the camera), or the camera may communicate wirelessly with local or remote data storage (e.g., a server on location or cloud storage). FIG. 3 is a photograph showing a side view of the light source of FIG. 1, with internal cabling running through the device, except at pivot points (see also FIG. 11).

[0041] FIG. 4 is a photograph showing a perspective end view of the light source of FIG. 1 attached to a distal end of a device for capturing virtual tour data. The blackout disk and mounting device are visible in the foreground. The mounting device, in the form of a threaded rod, may thread directly or indirectly into the base of a camera or video recorder. Other mounting device configurations, such as a clamp, with or without a quick release feature, may directly or indirectly grasp the camera or a base plate attached to the camera.

[0042] FIG. 5 and FIG. 6 are photographs showing side views of a device for capturing virtual tour data, according to an embodiment. FIG. 7 is a photograph showing a front view of the device of FIGS. 5 and 6. The device comprises a swing arm mounted to a mobile unit (e.g., a vest to be worn by a user), a light source mounted at a distal end of the swing arm, and a camera (not shown) attached to a mounting device of the light source. In the embodiment shown, the mounting device (e.g., threaded post) extends substantially horizontal to a ground surface when the device is in use. Although more or fewer pivot points may be used, the swing arm shown comprises four pivot points (see FIGS. 11, 12, 13, 14 and 15). Two of the four pivot points rotate around axes oriented perpendicular to one another (see FIG. 9), and three of the four pivot points rotate around axes substantially perpendicular to a ground surface when the device is in use. In an embodiment, the device may further include a battery pack providing power to the light source, the camera and/or a data storage system. The battery pack may be housed in a mobile device (see, e.g., FIG. 10).

[0043] FIG. 8 is a photograph showing details of the front of a vest having a device for capturing virtual tour data mounted thereon. In the embodiment shown, the vest comprises a plurality of pads to be secured to a user and a mechanism for adjusting the torso length, such as a bar with adjustment holes and a locking pin. A base plate of the swing arm is mounted to a plate on the chest area of the vest. FIG. 9 is a photograph showing details of the base plate attachment mechanism and two proximal pivots rotatable perpendicular to one another.

[0044] FIG. 10 is a photograph showing details of the back of a vest having a device for capturing virtual tour data mounted thereon. As shown, cables from the camera and/or light source extend to the back of the vest where a battery pack and/or hard drive may be housed in a pocket or container. Positioning the pocket/container on the back of the vest allows it to be out of the way of the swing arm, but other locations for placement of the pocket/container are possible.

[0045] FIG. 16 is a photograph of a device for capturing virtual tour data in a compact configuration, according to an embodiment. The compact configuration allows for easy stowage, and illustrates the extensive range of motion provided by the swing arm.
