Abstract: A wireless power transfer system including a driver coil array, a hexagonally-packed transmitter mat, a receiver coil, and a load coil for powering a medical implant. The magnetically coupled resonance between two isolated parts is established by an array of primary coils and a single small secondary coil to create a transcutaneous power link for implanted devices as moving targets. The primary isolated part includes a driver coil array magnetically coupled to a mat of hexagonally packed primary coils. Power is injected by the driver coils into the transmitter coils in the transmitter mat to maintain resonance in the presence of losses and power drawn by the receiver coil from the magnetic field. The implanted secondary isolated part includes a receiver coil magnetically coupled to a load coil. A rectification/filter system is connected to the load coil supplying DC power to the electronic circuits of the implant.

Abstract: A method for detecting spectral characteristics of multi-band moving objects. The method includes: 1) dividing a full field of view into several subfields of view, and scanning and extracting suspected objects in each subfield one by one; 2) correlating interrelated suspected objects in adjacent subfields via coordinates to determine objects of interest that exist in the full field of view; 3) calculating the speeds of the objects of interest; 4) calculating average speed of all of the objects of interest and classifying the objects of interest according to their average speed; 5) compensating and rectifying the objective spectrum obtained from calculation; and 6) matching the compensated and rectified objective spectrum with a spectrum fingerprint database whereby realizing recognition of the multi-band moving objects.

Abstract: A method for manufacturing parts and molds by: 1) slicing a three-dimensional CAD model of a part or mold; 2) planning a modeling path according to slicing data of the three-dimensional CAD model, whereby generating numerical control codes for modeling processing; and 3) performing fused deposition modeling of powders or wire material of metal, intermetallic compounds, ceramic and composite functional gradient materials by layer using a welding gun on a substrate layer via a numerical control gas shielded welding beam or laser beam according to a track specified by the numerical control code for each layer. A micro-roller or a micro-extrusion unit is installed at a contact area between melted and softened areas. The micro-roller or the micro-extrusion unit synchronously moves along with fused deposition area, which results in compressing and processing of the fused deposition area during the fused deposition modeling.

Abstract: A water treatment reactor, including: a reaction vessel; an electrode; a pulsed power supply; and a regulating assembly, the regulating assembly including a fixation cylinder, an insulation sleeve, and a copper cap. The pulsed power supply is in electric connection with the electrode. The fixation cylinder is fixed on a vessel wall of the reaction vessel. The insulation sleeve is disposed between the electrode and the fixation cylinder. The copper cap is disposed outside the insulation sleeve. An inner flange is disposed on one end of the copper cap. A protrusion is disposed on a middle part of the insulation sleeve and is sandwiched between the vessel wall and the inner flange of the copper cap. The protrusion includes at least two sections; and a rubber ring is disposed between two adjacent sections. The copper cap and the fixation cylinder are in a threaded connection.

Abstract: A method for restoring and enhancing a space based image of point or spot objects. The method includes: 1) dividing a space-variable degraded image into multiple space-invariant image sub-blocks, and constructing a point spread function for each of the image sub-blocks; 2) correcting each of the image sub-blocks via a space-invariant image correction method whereby obtaining a corrected image {circumflex over (f)}i for each of the image sub-blocks; and 3) stitching the corrected image sub-blocks {circumflex over (f)}i altogether via a stitching algorithm whereby obtaining a complete corrected image {circumflex over (f)}.

Abstract: A laser including a semiconductor laser stack group, a beam compositor, a pump beam collimator, a thin-disk laser crystal, a first and a second parabolic reflectors with the same facial contour function, a corrective reflector, an output mirror, and a jet-flow impact cooling system. The thin-disk laser crystal and the output mirror form a laser resonant cavity. The first parabolic reflector, second parabolic reflector, thin-disk laser crystal, and corrective reflector form a multi-pumping focus cavity. The jet-flow impact cooling system is used for cooling the thin-disk laser crystal. The pump light produced by the semiconductor laser stack group is composited by the beam compositor, collimated by the pump light collimator, and enters the multi-pumping focus cavity. Within the multi-pumping focus cavity, the pump light is focused, collimated, and deflected to converge on the thin-disk laser crystal. The laser resonant cavity produces and outputs a laser beam.
