A fluidic lens may include an optical surface configured for deflection dominated by bending stress. An adjustable concentric load may be applied to the optical surface to cause a clear aperture region of the optical surface to deflect with generally spherical curvature. Adjusting the concentric load controls the radius of curvature. An adjustable uniformly-distributed load may be applied to the optical surface by fluid pressure that causes the clear aperture region to deflect with an aspheric shape. Adjusting the pressure controls the asphericity of curvature. First and second fluids having similar densities and different refractive indexes may be disposed on either side of a deflectable optical surface to help balance gravitational loading on either side of the optical surface, thereby reducing gravity-associated aberrations.

An electrophoresis device is disclosed which separates cells, particles, proteins and other separands by collecting samples of decreasing electrophoretic mobility in a train of inverted cavities while an electric field is applied between said inverted cavities and one or more sample cuvettes containing a mixture of cells, particles, proteins or other separands. One circular plate is provided for the one or more sample cuvettes, and one circular plate is provided for the multiple collection cavities. The invention utilizes an innovative purification method that combines free electrophoresis and multistage extraction in an instrument capable of separating living cells, particles, and proteins in useful quantities at high concentrations. The purification method includes a method for dealing with electrolysis products, a technique for controlling the electrical energy input, and an approach for keeping the process isothermal. The invention solves many separation applications problems on earth and also in reduced gravity in space flight.

A test chamber is pivotably suspended in an aircraft, so that the center of gravity of the test chamber always self-actingly orients itself in the direction of the effective residual acceleration. To simulate a selected acceleration greater than 0 g and less than 1 g, the aircraft is flown along a parabolic flight path with a downward vertical acceleration such that the difference between Earth's gravitational acceleration and the aircraft's acceleration corresponds to the selected acceleration to be simulated. To simulate gravitational conditions on Mars, the aircraft is flown with a downward vertical acceleration of about 2 / 3 g, so that the residual acceleration acting on the test chamber is about 1 / 3 g. The atmospheric conditions, such as the gas composition, pressure and temperature, of Mars can also be established in the test chamber.

The invention discloses a suspension type self-adaptive weight reducing device for rehabilitation training and a rehabilitation training robot. The device comprises a foldable mobile training frame, alower limb training assistive device carrying device, a weight reducing vest, a pulley rope system and a self-adaptive weight reducing box, the box is internally provided with a rope winding device and a self-adaptive gravity following device, the rope winding device is connected with a rope roller through a coupling by means of a servo motor cooperating with a speed reducer, and the reduced gravity is provided for a patient by winding or releasing the rope; the rope is led out by the rope roller and winds around a pulley on the side face of a mounting plate to be connected with the weight reducing vest through a pulley block on the self-adaptive gravity following device, the gravity position is calculated by collecting the joint rotation angle of the patient, a motor of the self-adaptivegravity following device is controlled to drive a lead screw to rotate through the coupling, and a shifting board connected with a lead screw nut drives a movable pulley to do liner motion. In this way, the length of the suspension rope in the training process of the patient is adjusted, gravity following is achieved, and the roughly constant reduce gravity is maintained.

The invention relates to a wind power generator of a vertical shaft with gravity and friction reduced by magnetic suspension, which comprises a wind wheel, a generator with a stator, a rotor and a generator shaft, wherein, the permanent stator magnet and the permanent rotor magnet of a magnetic suspension bearing are respectively fixed on the stator and the rotor and arranged top down with the permanent stator magnet under the permanent rotor magnet and the two opposite surfaces have the same polarity. The permanent stator magnet and the permanent rotor magnet of the magnetic suspension bearing are arranged inside the generator with compact structure. The wind power generator has simple integral structure and convenient site installation. The clearance of the upwards running and the downwards running of the generator shaft is less than that of the two opposite surfaces of the permanent stator magnet and the permanent rotor magnet, thus avoiding the contact of the permanent stator magnet and the permanent rotor magnet and protecting the permanent stator magnet and the permanent rotor magnet automatically. After the disappearance of special external force, the generator shaft resetsautomatically.
