| 20110076904 | Buoy for Automated Data Collection and Transmittal - A buoy for automated collection and transmittal of data. Select embodiments allow calculation of mass balance using data collected from an ice floe. The buoy is adapted to be inserted into the water through an opening in ice so that the buoy floats with the ice floe, the top of the buoy protruding above the surface of the ice floe. The buoy walls are constructed of white PVC. One section of the buoy incorporates closed cell foam for maintaining buoyancy and a bottom section houses a counterweight for maintaining proper orientation of the buoy in the water, the buoy requiring no support from its surrounds while minimally impacting response of the surrounding ice to it. Multiple sensors are incorporated for gathering data and a satellite transmitter transmits the data to a remote user. | 03-31-2011 |
| 20120208414 | PLATFORM FOR COLLECTING MARINE ENERGY SOURCES - The invention relates to a platform for collecting marine energy sources, which comprises solar energy collecting devices, wind energy generating devices and tidal generating devices. The platform also comprises electric energy gathering devices for gathering and outputting electric energy output by the collecting devices or the generating devices. The devices are arranged on the platform on the sea surface. The platform comprises a support partially submerged under the sea surface, a table arranged on the support, and a mounting bracket arranged on the table and used for placing the solar energy collecting devices and the wind energy generating devices. | 08-16-2012 |
| 20140302732 | OCEANOGRAPHIC INFORMATION COLLECTION SYSTEM - An oceanographic information collection system includes an anchor arranged on a sea bottom, an intermediate buoy connected to the anchor and floating in a sea, a mooring cable connected at one end to the intermediate buoy and at another end to an observation buoy. The observation buoy includes a main body whose longitudinal direction is arranged in a flowing direction of an ocean current. A specific gravity adjuster is arranged in the main body and includes an expandable and shrinkable buoyancy bag, an antenna arranged on the main body and transfers data, and an observation unit arranged in the main body and acquires prescribed oceanographic information. The observation buoy floats upward by expanding the buoyancy bag of the specific gravity adjuster, and sinks by shrinking the buoyancy bag in order to stand by in the sea. The buoy can easily float, sink and stand by in the sea. | 10-09-2014 |
| 20220135187 | ADJUSTABLE AQUACULTURE APPARATUS - An adjustable aquaculture assembly including a container having a plurality of open sides and defining a retention space. The open sides are configured to allow flow through the retention space. A plurality of buoyancy members are positioned on the container. Each buoyancy member may be configured to be selectively filled with and emptied of air. A pump is coupled with the plurality of buoyancy members and is configured to control airflow to and from at least one of the plurality of buoyancy members. | 05-05-2022 |

| 20090286432 | Apparatus Having A Buoyant Structure That Resists Rotation - Apparatus includes a buoyant structure having a central vertical axis when floating in water and having at least one feature to reduce a rotation of the buoyant structure about the central vertical axis when floating in the water. The apparatus further includes an electronic camera assembly coupled to the buoyant structure. The electronic camera assembly is configured to generate an electronic image signal. The apparatus further includes a tubular structure coupled to the buoyant structure and configured to remain under the surface of the water. The tubular structure includes a watertight compartment and an electronic circuit assembly disposed within the watertight compartment. The electronic circuit assembly is coupled to receive the electronic image signal and is configured to generate an optical image signal representative of the electronic image signal. The apparatus further includes a fiber optic cable configured to carry the optical image signal. | 11-19-2009 |
