A fish tank includes a first water chamber for providing living space for fish; a second water chamber in fluid connection with the first water chamber with a grating therebetween. The openings of the grating are sized to keep the first water chamber and the second water chamber fluidly connected but prevent fish or other aquatic animals from entering the second water chamber. In an embodiment, a one-way valve allows water to flow out of the second water chamber and prevents water from flowing back into the first water chamber. A removable syringe with a plunger, a barrel and an orifice is provided such that when the orifice is connected to the one-way valve means and the plunger is pulled out of the barrel, water in the second water chamber flows into the barrel of the removable syringe through the one-way valve means.

An aquarium includes a tank body and a water pump, wherein the water pump includes a stator and a rotor and the tank body includes a tank wall; a rotor chamber arranged at one side of the tank wall close to inside of the tank body and configured to accommodate the rotor; a rotation shaft configured to support the rotor and arranged in the rotor chamber; an impeller configured to connect with the rotor and arranged in the rotor chamber; and a stator chamber configured to accommodate the stator, arranged at one side of the tank wall close to outside of the tank body and arranged corresponding to the rotor chamber so that the stator can drive the rotor.

A device for fish reproduction, hatching and larval culture including an aeration device, a first netted division plate, a second netted division plate, a first water pump, a first net cage, a second water pump, and a second net cage. When in use, the device is disposed in a pond. The pond includes a breeding area, a hatching area, and a nursery area, and each of the breeding area, the hatching area, and the nursery area communicates with the other two. The first netted division plate is disposed between the breeding area and the hatching area, and a first water recirculating loop is formed between the breeding area and the hatching area to drive water to flow from the breeding area to the hatching area, and back to the breeding area. The second netted division plate is disposed between the hatching area and the nursery area.

A filter arrangement for an aquarium is disclosed. The filter arrangement can include a filter housing assembly, a pump assembly, and a transfer tube assembly. In one aspect, the housing assembly and the pump assembly are separately constructed assemblies that are connected to each other via a first dampening member to prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. The filter arrangement can further include a second dampening member connecting the pump assembly with the transfer tube assembly to further prevent vibration and sound from being transmitted from the pump assembly to the filter housing assembly. A third dampening member can be provided at a location where the transfer tube assembly is supported within the filter housing assembly to further isolate vibration and sound from being transmitted from the pump assembly to the filter housing assembly via the transfer tube assembly.

Methods are proposed to define UE behavior for performing synchronization signal block (SSB) based radio link monitoring (RLM) and channel state information reference signal (CSI-RS) based RLM. In a first novel aspect, if CSI-RS based RLM-RS is not QCLed to any CORESET, then UE determines that CSI-RS RLM configuration is error and does not perform RLM accordingly. In a second novel aspect, SSB for RLM and RLM CSI-RS resources are configured with different numerologies. UE perform SSB based RLM and CSI-RS based RLM based on whether the SSB and CSI-RS resources are TDMed configured by the network. In a third novel aspect, when multiple SMTC configurations are configured to UE, UE determines an SMTC period and whether SMTC and RLM-RS are overlapped for the purpose of RLM evaluation period determination.

A fluid pump assembly is used in combination with a container having a wall. The pump assembly comprises a first casing disposed outside the container in contact with the wall, a first magnetic assembly mounted to the first casing and operatively associated with a drive motor, a second casing disposed inside the container in contact with the wall, and a second magnetic assembly mounted to the second casing and operatively associated with an propeller. The first magnetic assembly includes a rotatable magnetic drive member drivingly coupled to the drive motor. The magnetic drive member is magnetically coupled to the magnetic driven member through the wall for imparting a rotary driving force of the drive motor to the propeller. Furthermore, the second casing is detachably connected to the second side of the wall of the container solely by magnetic attraction force between the first and second magnetic assemblies.

The disclosure provides an outdoor device for simulating a pond ecosystem comprising a plurality of simulated ponds connected together by pipelines and including an adjusting pool, a plurality of control groups and a plurality of treatment groups with different concentrations; the plurality of control groups and the treatment groups are randomly distributed in the ponds according to a random draw method or a random allocation method, and the adjusting pool is a transfer station for water inlets and outlets of the ponds. According to the device, the plurality of control groups and treatment groups are arranged in a system, achieving a scale of a middle-scale pond ecological simulation system, which can stimulate an actual complex hydrostatic ecological system including a plurality of aquatic macrophytes, algae, zooplankton, benthos and microorganisms, and evaluate the effects of the complex ecological efficiency caused by chemical pollutants entering an actual water body.

An attachable flow rate controlling device comprising a flow rate control unit and a fastener is disclosed. The flow rate control unit comprises a chamber and an adjustable valve. The adjustable valve is configured to control the rate of water flow by converting the adjustable valve to turn on/off, so that a fish keeper is able to control the rate of water flow from an aquarium. Additionally, the flow rate control unit is fixed securely or pasted around an opening of a bucket or on a flat surface by the fastener. As such, the fish keeper can change the water in the aquarium and control the flow rate of the water from the aquarium. The attachable flow rate controlling device is controlled by rotating the adjustable valve hence enabling the fish keeper to use the attachable flow rate controlling device without repeatedly refilling the siphon hose with water.

Apparatus and method for collecting and decompressing one or more live specimens from a relatively high-pressure environment. The apparatus includes at least one hyperbaric chamber having an inner jar and an outer jar, the inner jar being insertable into the outer jar. A pump is configured to provide a pressurized fluid to the hyperbaric chamber. The inner and outer jars are respectively dimensioned such that an annular gap is created between them when the inner jar is inserted into the outer jar. The annular gap is configured as a return path for the pressurized fluid to travel from a second outer end to a first outer end of the outer jar. At least one pressure control valve is operatively connected to and configured to control an internal pressure of the hyperbaric chamber. The pressure control valve is selectively adjusted to decompress the live specimens.
