摘要： Apparatus for controlling algae and bio-organisms in bodies of fluids, such as water. The algae control system includes a power unit and a transducer unit that includes a sonic head that radiates in multiple directions. The power unit connects to various power sources, including a mains supply connection, a solar panel array, and/or a battery. The power unit is electrically connected to the transducer unit. The sonic head includes a driver and a transducer subassembly. The driver excites the transducer assembly to emit ultrasonic waves at various frequencies with varying durations of on/off periods. Emissions at a high density of frequencies are enabled by the transducers. The frequencies include the critical structural resonant frequency for each microorganism to be controlled. The power unit and driver each include a processor in communication with each other. The processors store and execute a program for a selected application configuration.

摘要： Apparatus for controlling bio-organisms in bodies of water. The algae control system includes a power unit and a transducer unit that radiates in multiple directions. The transducer unit includes a variable power driver and a transducer subassembly. The power from the driver varies to maintain a maximum, constant transducer sonic output over its bandwidth. The transducer assembly includes at least one transducer that includes a pair of blocks with at least one piezoelectric element therebetween. One embodiment has a single, disc-shaped element adhesively secured between said blocks. The transducer is excited by applying power to the pair of blocks. Another embodiment has at least one ring-shaped elements compressed between the two blocks by way of a fastener. The transducer is excited by applying power, in one embodiment, between the blocks and a conductor between a pair of ring-shaped elements, or in another embodiment, between the pair of blocks.

摘要： Apparatus for protecting submerged equipment from biogrowth. In one embodiment, a submerged, underwater ultrasonic transducer assembly is enclosed in an isolation chamber that contains a zone that is free of bio organisms. The isolating chamber encloses the transducer assembly to provide an outer surface exposed to the body of water where that outer surface is distanced sufficiently from the transducer assembly to ensure algae is inhibited from growing on the outer surface. The isolating chamber is a water-tight enclosure filled with a liquid. In another embodiment, the transducer assembly is surrounded by a light array that directs illumination toward the assembly. The illumination is at a wavelength that inhibits biogrowth. The light array includes a plurality of light strips with spaced apart lights. The light strips are supported by a bracket such that the transducer assembly is fully exposed to the illumination from the light strips.
