Abstract: A mobile camera crane unit includes a camera crane having a column mounted on the chassis of a vehicle or mobile base. A drive system is configured to move the column linearly on the chassis between a use position at or near the back end of the mobile base, and a transport position further forward on the mobile base. A method of operating a camera crane unit of the type having a camera crane on a mobile base includes operating the mobile base to move the camera crane unit to a filming location with the camera crane in a transport position on the mobile base, moving the camera crane linearly to a use position spaced apart from the transport position and behind the transport position on the mobile base, and operating the camera crane.

Abstract: A telescoping crane has an adjustable, pivoting payload, and a counterbalance mechanism that automatically compensates for the position of the telescoping crane and movement of the payload relative to the crane.

Abstract: Underwater LED lights with enhanced cooling to allow the use of substantial numbers of high power LEDs. In all embodiments, the majority of the heat given off by the LEDs is transferred to the housing of the underwater light by heat transfer techniques other than by convection of the air or other gases within the enclosure, providing direct heat conveyance from the LEDs to or through the light enclosure walls, by conduction through a thermal conductor or by or as augmented by heat pipes to the inside wall of the enclosure or through the wall of the enclosure to the water. Various embodiments are disclosed.
