    摘要: Techniques for reducing biofouling on optical equipment, using minimum power in a marine environment are provided. An example apparatus for reducing biofouling in a marine environment includes a housing including a cavity and a convex ultraviolet transparent window disposed over the cavity, an optical device disposed in the cavity and directed towards the convex ultraviolet transparent window, one or more ultraviolet light emitting diodes disposed in the cavity and directed toward the convex ultraviolet transparent window, and a controller operably coupled to the one or more ultraviolet light emitting diodes and configured to provide at least one lamp power function to the one or more ultraviolet light emitting diodes, wherein the at least one lamp power function is based on at least a flash power value, a flash duration, and a rest duration.

    摘要: The motor vehicle camera housing assembly comprises first and second housing parts that define an inner space and joining means for joining housing parts together including a sheet material wound more than one turn around the housing assembly. The sheet material has a support layer and at least one adhesive layer adhered to respective outer surfaces of the housing parts at least partially filling a gap formed in an overlapping portion defined by two edges of the sheet material when wound on the housing parts such that they are sealingly joined together.

    摘要: The invention relates to an underwater digital video camera having an auto record system for automatically starting and stopping video recording at predetermined depths. The camera receives a current depth from a depth gauge and holds a sequence of recent currents depths and auto record settings such as a start trigger depth and a stop trigger depth, wherein the auto record system is adapted to, after the start/stop trigger depth is arrived at or passed for increasing/decreasing depths, start/stop video recording.
