The present invention relates to a variable-torque magnetorheologically actuated prosthetic knee which utilizes a plurality of interspersed and alternating rotors and stators to shear magnetorheological fluid in gaps formed therebetween. Advantageously, by operating in the "shear mode" there is substantially no or negligible fluid pressure buildup or change. Moreover, the multiple MR fluid gaps or flux interfaces desirably allow for the production of a large torque at low speed-eliminating the need for a transmission-and also for a wide dynamic torque range. One embodiment of the invention allows the rotors and/or stators to close the gaps therebetween to create a frictional torque component, thereby forming a "hybrid" braking system which provides a total torque or damping which is a combination of viscous torque and frictional torque.

The objective of this invention, on demand hydrogen enhancement system for internal and external combustion engine, is to develop a continuous non pressurized water electrolyzer from clean water (not pure water or distil water) generator system. The mixed hydrogen gas and oxygen gas called “Oxyhydrogen”. Oxyhydrogen use as catalyse for internal and external combustion engine to increase fuel flame speed. It can use with variety fuels such as Ethanol, Methanol, Gasohol, Gasoline, Diesel, Bio Diesel, LPG, CNG, and LNG. This system can reduce fuel consumption, increase fuel efficiency, increase torque, reduce emissions, and reduce engine temperatures. The system required no cooling fan and electrolytic solution circulating pump. The system has less heat loss and very low electrical consumption. Oxyhydrogen will produce on demand as the engine RPM and load of generator. The control unit detects signal frequency from the alternator. Gas production rate low at low RPM and use less current and gas production will high at high RPM and use higher current. This can save lot of energy for the electrolysis process. In the past, water electrolysis use direct current (D.C.). In this invention the inventor uses D.C. with Frequency Modulate (FM) pulse width modulator (PWM) instead of Amplitude Modulator (AM) to control the electrolyzer (FMPWM). This circuit had current detector for automatic current adjustment and over current protection.

The inventive vibration absorber comprises an execution unit, a control unit and a sensor. The execution unit consists of a magnetic inductor, a coil, a magnetic rheological elastic body, a vibration-absorbing mass block and a base. The above magnetic inductor consists of inner and outer sleeves, or a U-shaped iron-core and an armature or top and bottom plates and a column iron-core. Between inner and outer sleeves, the U-shaped iron-core and the armature or the top and bottom plates are filled the magnetic rheological elastic bodies. By regulating the voltage on the coil, the rigidity and the elasticity of the magnetic rheological elastic body are regulated to make its vibration frequency change, so as to make the vibration frequency of the vibration absorber execution unit is the same as that of the vibration-damping object.

The basic principles of the method for heavy metals electroextraction from technological solutions and wastewater includes pretreating to remove Chromium-6 and high concentrations of heavy metals and periodically treating in a six-electrode bipolar cylindrical electroreactor made of non-conducting material to achieve lower accepted levels of impurities. Six cylindrical steel electrodes form two triode stacks and are fed with three-phase alternating current of commercial frequency (50-60 Hz), which can be pulsed. Each phase of the three-phase current is connected to three electrodes of one triode stack or in parallel to two triode stacks. The parallel connection of three-phase current to two triode stacks is performed so that the same phase of the three phase current is connected in parallel with each two opposite electrodes of six electrodes located along the periphery, or with two adjacent electrodes. A bipolar stationary aluminum electrode is situated in the inter-electrode space. In one of the embodiments, the bipolar electrode is made of a perforated heat-resistant plastic container filled with secondary aluminum and duralumin scrap. In another embodiment, the bipolar electrode of aluminum or duralumin scrap may be made without a perforated container and is placed in the inter-electrode space as a bulk scrap. In this case, to prevent shorts, each of six steel electrodes is placed in isolated perforated plastic shell with holes of 5 mm in diameter. Non-ferrous metals are extracted in a form of ferrite-chromites, and aluminates as well as hydroxyl salts deposited in the inter-electrode space without electrolysis deposits on electrodes. Deposits are separated from solution by known methods of filtration.

An electric toothbrush with a handle and a brush member having a brush head, individual cylindrical bristle holders with tufts of bristles held rotatably in the brush head. They are set into an oscillatory rotating movement by means of a connecting rod executing a reciprocating sliding movement and simultaneously an oscillatory movement about its longitudinal axis, with transverse grooves, disposed therein. In addition, a bristle holder plate in the brush head is held so as to oscillate about a shaft running in the longitudinal direction of the toothbrush. Thus, during the oscillatory movement of the bristle holders the bristle holder plate swivels back and forth in synchronism with the connecting rod.

An optical engine for an image projector comprises a light source, a taper rod, at least one light condenser, a prism module, a Digital Micromirror Device (DMD) and a projection lens set. One end of the taper rod is adjacent to the light source. Light generated by the light source is guided by the taper rod following a light path. The taper rod has increasing sizes of cross-sections along the light path, so as to decrease the dispersion angle of light, make the light more uniform, and increase the brightness of light. The prism module includes a first prism having a right triangle cross-section and a second prism having a wedge cross-section. The prism module receives the light from the condenser, passes the light toward the DMD, receives the light reflected by the DMD, and then passes the reflected light toward the projection lens set. The projection lens set projects the light on an external projection plane.
