Abstract: Provided are a multi-function device for intensive shrimp farming and intensive shrimp farming systems using this device. The system comprises: shrimp ponds (100) with brackish water pumped from rivers or seas then treated with chemicals, sedimentation and micro-organisms; at least one multifunction device (200) to generate water flow, dissolve molecular oxygen, deliver and dispense shrimp feed and provide solution containing minerals, micro-organisms and other additives; pure oxygen supply device (300) capable of generating oxygen from the air to supply oxygen with purity higher than 90% to water in intensive culture pond to achieve consistently higher concentrations of dissolved oxygen saturated dissolved oxygen concentration; a network of porous sheets floats on the water to reduce the diffusion of oxygen molecules from the water to the air; and a network of lights for providing artificial light to change the feeding cycle of shrimp with industrial and natural food.

Abstract: There is provided a smart aquaculture growth and health monitoring system and method for monitoring the growth and health of an aquatic species present in an aquaculture growth habitat. The system comprises a georeferenced location beacon of the growth habitat, a sample container to sample water and aquatic species from the growth habitat and being configured to permit an electronic device having camera such as a smart phone to acquire digital visual data on said sample, a processor is communicatively linkable to the electronic device and optionally to a communications network, the processor being operable to receive the digital visual data; determine, based on the digital visual data, growth and/or health parameters of the aquatic species in the sample; and to retransmit data on the growth and/or health parameters of the aquatic species back to the electronic device.

Abstract: The ANGULAR ROTATION LOCKING MECHANISM (ARLM) is used on cargo transport vehicles such as trucks and ships. The structure has a large load capacity, the ability to open and close easily, flexibly, but ensures the ability to lock the brake during the transport of the vehicle, in all weather conditions. Because of a purely mechanical structure, the maintenance and repair process is simple. The main point of the design is the self-positioning between the front pedestal shaft and the locking blade during operation.

Abstract: A self-balancing Two-Rotation Driving Mechanism (TRDM) uses parallelogram and has low weight, high load, high accuracy, quick response and good adaptation with multi equipment. A longitudinal rotation motor assembly is constrained fully with a base assembly and drives a longitudinal rotation assembly through connecting rod parallelogram. The lateral rotation motor assembly is assembled in the hub of a longitudinal rotation assembly and rotates an equipment clamping assembly in a lateral direction. Generally, the TRDM can drive equipment clamping assembly in two rotations, with longitudinal rotation in the range of ±45° and lateral rotation in range of ±20°. A rotation limitation is reached when limitation shafts touch the end of respective grooves.

Abstract: Integration driving mechanism for fin control assembly applied for UAV, aerial observation equipment, comprises: the control assembly, the fin root assembly, the fin shaft. The control assembly is small size, high temperature operation, waterproof ability, vibration resistance, easily replacement and reparation that is still warrant the operation condition.
