    Abstract: Various technologies described herein pertain to assembling electronic devices into a microsystem. The electronic devices are disposed in a solution. Light can be applied to the electronic devices in the solution. The electronic devices can generate currents responsive to the light applied to the electronic devices in the solution, and the currents can cause electrochemical reactions that functionalize regions on surfaces of the electronic devices. Additionally or alternatively, the light applied to the electronic devices in the solution can cause the electronic devices to generate electric fields, which can orient the electronic devices and/or induce movement of the electronic devices with respect to a receiving substrate. Further, electrodes on a receiving substrate can be biased to attract and form connections with the electronic devices having the functionalized regions on the surfaces. The microsystem can include the receiving substrate and the electronic devices connected to the receiving substrate.

  • Patent number: 9017526
    Abstract: The disclosed embodiments relate to methods and apparatus for removing material from a substrate. In various implementations, conductive material is removed from a sidewall of a previously etched feature such as a trench, hole or pillar on a semiconductor substrate. In practicing the techniques herein, a substrate is provided in a reaction chamber that is divided into an upper plasma generation chamber and a lower processing chamber by a corrugated ion extractor plate with apertures therethrough. The extractor plate is corrugated such that the plasma sheath follows the shape of the extractor plate, such that ions enter the lower processing chamber at an angle relative to the substrate. As such, during processing, ions are able to penetrate into previously etched features and strike the substrate on the sidewalls of such features. Through this mechanism, the material on the sidewalls of the features may be removed.

Parallel pairs of electrode plates are situated in vertical position in the container or tank and form parallel vertical passages therebetween for the water to be treated. In the pairs of electrode plate at least one electrode plate comprises holes connected to a feed pump for an auxiliary medium. Said pairs of electrode plates are positioned between the inlet and outlet in the container or tank such that in at least part of the flow route between the inlet and outlet the water passes upwards in the vertical passages. The feed pump for the water to be treated and/or the feed pump for the auxiliary medium is a pulsating feed pump.

  • Patent number: 8317985
    Abstract: An electrolyte electrolyzer adapted to create hydrogen and oxygen from electrolyte fluid at or near atmospheric pressure. The electrolyzer is comprised in a preferred form of a plurality of cells which collectively create oxygen and hydrogen chambers separated by an ion permeable membrane. The electrolyzer is further defined by a passive electrode that is electrically interposed between a charged anode and cathode. The chambers defined by the cells are in communication with oxygen and hydrogen supply lines to transfer the hydrogen gas from the unit.

  • Patent number: 8308919
    Abstract: An electrolysis device to separate water into its more economically valuable constituent hydrogen and oxygen gases. A neutral plate is interleaved between every magnetically charged electrode in an electrode stack to provide a means of spark suppression, a physical barrier between the hydrogen gas created at the cathode and oxygen gas created at the cathode, and to reduce deterioration of electrode surfaces caused by alternating polarity from an anode state to a cathode state. Scale of electrolysis cell electrodes are partially cleaned through a cycling of system polarity through a neutral electrode period. A means is provided to isolate and segregate dissociated hydrogen and oxygen gas.

  • Patent number: 8307484
    Abstract: An automated self-propelled pool cleaner having a housing, a water pump for moving water through the housing, drive means for moving the pool cleaner over the surface of the salt water pool to be cleaned, and an integral electrochemical chlorine generator mounted in the housing, includes a processor/controller that is programmed to activate the chlorine generator, the pump and drive means in predetermined operational sequences that minimize wear and tear on the water pump and drive means, while at the same time distribute and maintain a safe level of sanitizing chlorine in the pool, to thereby obviate the need for an in-line chlorinator or other chemical additive treatments; an optional automated sensor device can be provided to activate a secondary maintenance program which enables the pool cleaner to operate over prolonged periods of time as the sole means for filtering and sanitizing the pool water.

  • Patent number: 8303798
    Abstract: The invention is a unit that produces Hydrogen Gas (Browns Gas (HHO)) that can be used as an assist to diesel and gas engines. The gas is produced from distilled water, using our stainless steel plate design. The patent should apply to the internal plate placement and design. The internal design of the unit allows it to produce significantly more hydrogen, drawing significantly less current or electricity from its power source. The internal design is in the placement of positive, negative and neutral plates to produce the gas.

  • Patent number: 8282812
    Abstract: An apparatus for producing hydrogen from salt water by electrolysis. The apparatus includes a cathode plate and an anode plate spaced apart from the cathode plate. The apparatus also includes a cathode end connector for electrically connecting the cathode plate to a negative terminal of a direct current electrical power supply, and an anode end connector for electrically connecting the anode plate to a positive terminal of the direct current electrical power supply. The cathode plate is made from aluminum, and the anode plate is made from zinc. The aluminum cathode plate may have a multiplicity of apertures therein. It has been determined that the aluminum cathode plate and the zinc anode plate tend to provide an effective combination for salt water electrolysis.

  • Publication number: 20120228149
    Abstract: Method and apparatus for electrochemical generation of quaternary ammonium hypohalite salts, which may be combined with the capabilities of free chlorine to form a novel biocidal system. An aqueous solution preferably comprising dissolved quaternary ammonium halide salts is electrolyzed, which converts the halide component of the quaternary ammonium salt to the corresponding halogen. The halogen dissolves in the aqueous solution producing hypohalous acid and hypohalite anion. A combination of one or more quaternary ammonium compounds and a halide salt, surfactant, and/or germicide may be electrolyzed. The solution may be incorporated into a delivery system for example, a spray bottle or hand sanitizer, or as part of a dispensing system whereby quaternary ammonium halide salts absorbed onto wipes can be dispensed as quaternary ammonium hypohalite salts.
