Abstract: A portable, collapsible video production system includes a case having a top lid connected to a bottom lid, a lift rigidly secured within the case to the top lid or the bottom lid, and a collapsible camera system rigidly secured to a top of the lift. The camera system includes a bottom frame member housing a computer with a screen, a middle frame member housing a transparent substrate that, when angled with respect to the bottom frame member, is configured to project an image of the screen to a user facing the case, and a top frame member housing a camera that, when angled with respect to the bottom frame member, is configured to aim the camera through the transparent substrate at a user facing the case. The bottom frame, the middle frame, and the upper frame are pivotably connected to each other along a hinge axis.

Abstract: Ocean thermal energy conversion plants can include: an operations center located onshore; a bottom-founded structure located offshore, the bottom-founded structure containing plant evaporators and plant condensers; and control cables extending between the operations center and plant machinery in the bottom-founded structure. Methods of providing electricity can include: transmitting signals from an operations center located onshore to an unmanned structure located offshore; and operating evaporators, condensers, and pumps located in the unmanned structure in response to the signals to generate between 0.5 megawatts and 15 megawatts of electricity in the unmanned structure.

Abstract: An power generation structure comprising a portion having a first deck portion comprising an integral multi-stage evaporator system, a second deck portion comprising an integral multi-stage condensing system, a third deck portion housing power generation equipment, a cold water pipe, and a cold water pipe connection. The the evaporator and condenser systems include a multi-stage cascading heat exchange system. Warm water conduits in the first deck portion and cold water conduits in the second deck portion are integral to the structure of the portion of the platform.

Abstract: A chin rest includes a body having opposing sides, a front, a back, a top having a top surface, and a bottom having a bottom surface. The top further defines a top plane between a front and back of the top, and the bottom defines a bottom plane between a front of the bottom and a back of the bottom. The top plane and bottom plane form an angle so that the chin rest can comfortable sit between a user's chin and the user's chest, with the user's chin resting on the top surface, and the bottom surface engaged against the user's upper chest. The user's head can be comfortably supported while the user is seated, allowing the user to relax muscles in the neck and avoid strain and other issues normally associated with resting without support in a seated position.

Abstract: A heat exchanger includes heat exchanger plates in a stacked arrangement such that each heat exchanger plate is spaced apart from the adjacent heat exchanger plate. The space between adjacent heat exchanger plates defines an external fluid passageway, and each external fluid passageway is configured to receive a first fluid. Each heat exchanger plate includes a peripheral edge, an internal fluid passageway configured to receive a second fluid. The internal fluid passageway includes an inlet and an outlet that open at the peripheral edge. The heat exchanger further includes a manifold having a supply chamber in fluid communication with the inlet of each heat exchanger plate and a discharge chamber in fluid communication with the outlet of each heat exchanger plate.

Abstract: A method of assembling a pipe on a water-supported floating platform is provided. The platform includes an open central bay, and a gantry on the platform is arranged so as to surround at least a portion of the bay. The method includes providing a pipe intake assembly and staves on the platform; transferring the pipe intake assembly to the interior space of the bay; assembling the individual staves on the pipe intake assembly in an offset construction; lowering the pipe portion within the bay and into the water until the upper ends of the staves reside within a lower portion of the gantry; increasing the length of the pipe portion by assembling additional staves to the upper ends of the assembled staves; and repeating the step of increasing the length of the portion of the pipe until the pipe has a desired length.
