Abstract: Systems, methods, and computer-readable media are provided for redundantly storing and authenticating event related video data from one or more cameras using a video recording manager device. Additional copies of event related video data are persisted across various storage devices including any combination of internal camera storage, remote storage, and one or more storage mediums associated with the video recording manager device. The stored video data is augmented with authentication metadata to preserve the authenticity such that the video data is suitable as evidence.

Abstract: A device for coupling a propulsor to a marine vessel. The device includes a mounting bracket configured for attachment to the marine vessel. A support frame has a carriage and is configured for the propulsor to be coupled thereto, where the carriage is configured to slidably engage with the mounting bracket into a fixed position. A member is manually engageable to prevent the carriage from sliding out of the fixed position. The propulsor is coupled to the marine vessel by sliding the carriage into the fixed position and engaging the member, where the propulsor is operable to propel the marine vessel in water when the carriage is in the fixed position, and where the propulsor is configured for decoupling from the marine vessel by disengaging the member and sliding the carriage out of engagement with the mounting bracket.

Abstract: A synchronously deployable tetrahedral truss beam with orthogonally-hinged diagonals, having uniquely-connected transverse members and folding chordal members, where a plurality of bays can extend and retract in a coordinated manner without need for a deployment canister mechanism or other assembling means. The triangular cross-section truss can be adapted to deploy pre-attached panels or nodally-attached payload components. These triangular beams can be mounted side-by-side with a common chord to create a synchronously deployable trapezoidal cross-section beam or space-frame. Both the triangular and trapezoidal configurations can be adapted to deploy with a prescribed curvature of the longitudinal axis, and form perimeter trusses which can be post-tensioned for maximum structural performance.

Abstract: A versatile book is disclosed for hanging pneumatically actuated devices (e.g., airguns or spray guns). In the preferred embodiment, the versatile hook comprises: a hook body having a base with an annular section that defines a through-space corresponding to the shape of the pneumatic device's cylindrical extension tube or barrel; a hook-shaped extension attached to the body; and, positioning-and-mounting means for selectively positioning the hook, around and along the barrel, and thereafter mounting the body in a temporarily fixed position onto the barrel, with the hook-shaped extension facing towards or away from the discharge nozzle. Upon loosening a bolt, the preferred hook can be reoriented.

Abstract: A humidity controller (12) for an outdoor storage container (10) is installed with a clearance fit in an apertured portion of a vertical wall (11) of the container (10). The humidity controller (12) comprises a frame assembly (13) to which a bed of solid desiccant material (14) and a transparent cover (15) are secured. Solar energy incident upon the transparent cover (15) is transmitted into a passageway between the bed of desiccant material (14) and the transparent cover (15), thereby heating air in the passageway and also heating a surface of the bed of desiccant material (14) exposed to the air in the passageway. Moisture adsorbed on bed of desiccant material (14) is vaporized by the solar energy, thereby establishing a concentration gradient for moisture in the bed of desiccant material (14) such that moisture is drawn toward the passageway for vaporization.
