A method of forming a three dimensional object using a low pressure cold spray process for is disclosed. Powdered material is delivered at a temperature below the melting point of the powdered material. A nozzle of a cold spray gun is aligned at an angle &#x3b8;to the substrate. The powdered material is delivered at a supersonic speed to the substrate causing the powdered material to adhere to the substrate for forming a first layer of material. An amount of optical distortion caused by the first layer of material adhered to the substrate is determined relative to the substrate and the nozzle is reoriented to an angle &#x3b8;being offset from an axis defined by the first layer of material. A second layer of material is deposited onto the first layer of material with the nozzle being oriented at the angle &#x3b8;to the first layer of material.

A nozzle element for applying powder material to a substrate is provided. The powdered material is applied from the nozzle element onto the substrate generating a coating of the powder material defined by a first film thickness and a first particle size of the powder material. A deformation nozzle element is provided for spraying shot toward the coating of powder material disposed upon the substrate deforming particles of the powder material disposed in the coating forming a second particle size being smaller than the first particle size and deforming the coating to define a second film thickness being less than the first film thickness.

Apparatus and method for cold spraying and coating processing

A reactive hopper assembly for feeding a low pressure cold spray applicator for applying powder coatings is disclosed. A powder feed cartridge provides powder feed to a reaction chamber. An impeller housing is interconnected with the reaction chamber for receiving powder feed from the reaction chamber for metering powder feed received from the reaction chamber. A hopper vessel receives metered powder feed from the impeller housing for providing powder to the low pressure cold spray applicator. The reaction chamber is fluidly connected to a source of a reactive gas for chemically modifying the powder feed for in situ reducing surface oxidation of the powder feed.

A method and apparatus is disclosed for slow wave sleep improvement. The method includes recording a biosignal from a skin area of a patient using an electrode system. The slow wave stage of NREM sleep is detected by analyzing an oscillation rate of the biosignal. If the slow wave stage is detected, threshold electrocutaneous stimulation is applied to improve the quality of sleep. The described embodiment relates to an apparatus for slow wave sleep improvement comprising an electrode system, a measuring unit, a therapy unit and a processor. The processor is coupled to the measurement unit for receiving the biosignal corresponding to the electrodermal activity. The processor proceses the biosignal to determine the slow wave sleep stage and activates the therapy unit to deliver threshold electrocutaneous therapy to the patient with the purpose of improving the slow wave sleep stage.

A method of fabricating ultrasound bone phantom material compatible with magnetic resonance imaging (MRI) is provided. The bone phantom material has ultrasound and physical parameters that are characteristic of human cortical and trabecular bones, and is well suited for the fabrication of bone phantoms intended for the development and testing of ultrasound medical diagnostic imaging techniques as well as high-intensity focused ultrasound (HIFU) therapy methods and other MRI imaging applications.

A portable gas dynamic cold spray gun eliminates many of the inherent limitations of the prior art by minimizing a scatter of operating parameters and improving its efficiency. According to one feature of the present invention, the powder flow rate is continuously measured so that the powder flow rate and/or the flow rate of the pressurized gas can be adjusted accordingly in order to control the deposition efficiency of the spray gun.

A method and apparatus for making carbon-encapsulated ultrafine metal particles, in which metal powder intended for encapsulation is injected at a rate up to 25 grams per minutes into a plasma arc so that the metal powder is vaporized. The vaporized metal powder is then mixed with an active gas flow, which consists of hydrocarbons, filled in the surrounding area of the plasma arc, and thereby the vaporized metal powder and the active gas interact continuously producing carbon encapsulated ultrafine metal particles that are remarkably predictable in particle size, distribution of sizes and atomic composition.
