Modular or cartridge-type membrane units utilize hollow, cylindrical tubular housings or receivers to house strings of removable membrane modules (elements) and normally comprise arrays of pipes that act as membrane module housings. A pseudo header for fluidly interconnecting the array of pipes reduces weight and cost. The pseudo header may comprise portions that are buried within skid components such as the toe bar. An internal low friction coating permits a larger number of membrane cartridges to be utilized in any cylindrical tubular membrane housing. A center feed pseudo header permits flow in two directions through the tubular membrane housing to double hydraulic capacity.

The invention discloses an underwater sub-wavelength resolution ratio three-dimensional imaging method. The underwater sub-wavelength resolution ratio three-dimensional imaging method includes the following steps: (1) a sound signal is emitted; (2) acoustic lens wave beams are formed; (3) the sound signal is received and adjusted; (4) an image is processed and displayed. A two dimensional datum is obtained according to an imaging rule of an acoustic lens, a distance datum is obtained by utilizing an emission time and a receiving time, and a three dimensional underwater sound datum is obtained by combining with an electric signal received by a underwater sound sensor. The three dimensional underwater sound image datum undergoes image enhancement and image segmentation and a three dimensional image of a target is achieved by use of an open-sourcing visualization program library visualization toolkit (VTK). A reflected sound wave is focused through the acoustic lens and forms the wave beam. Hardware circuits of a normal imaging system are greatly reduced. A sub-wavelength image is achieved due to the characteristic of negative refraction of a phonon crystal. The novel underwater sound sensor with a mesoscopic pressure resistance is utilized, the underwater sound sensor responds to an underwater sound signal well, and a faint underwater signal can be effectively transformed.

The invention belongs to the technical field of application of solar power generation grid-connection self-use power supply, and in particular relates to a structure and a method for a solar power grid-connection self-use multi-functional system. In order to endow a solar power generation system with functions of power generation, grid connection and self-use, a technical scheme is changed through a direct current power regulating circuit, a system allocating control circuit, an electronic control switch group and a power on-off controllers, wherein according to technical scheme, the system structure is that solar power generation systems can supply power to alternating loads of users only through storage batteries and inverters, and the internal power path is single. Therefore, when the multi-purpose solar power generation power supply system which can generate power, connect the grids and realize self-use is constructed, the system hardware scale is reduced, the structure of the system and formation of the internal power path are optimized, power consumption and resource waste are reduced, the using efficiency of solar power is greatly improved, and return on investment is greatly increased.

An image recognition apparatus determines whether an image of a pedestrian is captured in a frame of video data captured by a vehicle mounted camera. A pre-processing unit determines a detection block from within a frame, and cuts out block image data corresponding to the detection block from the frame. Block data with a predetermined size that is smaller than the size of the detection block is created from the block image data. A neuro calculation unit executes neuro calculation on the block data, and calculates an output synapse. A post-processing unit determines whether a pedestrian exists within the detection block on the basis of the output synapse. When a pedestrian is detected, the post-processing unit creates result data, which is obtained by superimposing the detection block within which the pedestrian was detected onto the frame.

Moreover, with the shared memory, the speed and stability of data interaction between the main control unit and the execution unit may be improved.

A power amplifier (101) amplifies a high-frequency signal. A coupler (102) monitors the signal power Pmoni amplified by the amplifier (101). A detector (103) carries out linear half-wave rectification of the input above the forward voltage of a diode, integrates it using an RC filter, and produces a detected voltage Vdet. A gain/offset amplifier (104) amplifies the detected voltage Vdet and/or applies an offset voltage to convert the detected voltage Vdet to a desired voltage, and the resulting voltage serves as the gate voltage of the power amplifier (101). As a result, power consumption in a low-power region of a power amplifier is reduced, and hardware is downsized.
