Abstract: A method of fabricating a porous or partially porous three-dimensional metal article for use as a tissue ingrowth surface on a prosthesis. The porous article is formed using direct laser remelting in a cross section of a layer of metallic powder on a build platform without fusing thereto. The power, speed, spot size and beam overlap of the scanning laser is coordinated so that a predetermined porosity of the metallic powder can be achieved. Laser factors also vary depending from the thickness of the powder layer, type of metallic powder and size and size distribution of the powder particles. Successive depositing and remelting of individual layers are repeated until the article is fully formed by a layer-by-layer fashion. In an additional embodiment, a first layer of metallic powder may be deposited on a solid base or core and fused thereto.

Abstract: A floor care appliance such as a vacuum cleaner is provided having a traction wheel powered edge cleaner comprised of a vertical axis rotary agitator which is affixed to either the right or left side of the suction nozzle. The agitator is rotated by the traction wheel when the vacuum cleaner is disposed along a wall surface and moved relative to the wall surface. The rotating action of the agitator sweeps dirt particles off of the wall surface and along the edge of the wall surface into the path of the suction nozzle for pickup. When not in use the edge cleaner is stored in the accessory storage rack like other accessory tools. The agitator can have differing agitator elements such as bristles or a fluff wheel.

Abstract: Method for detecting partial discharges and diagnostic system for electrical apparatus. The invention provides a method of detecting partial discharges in an electrical appliance insulated in a receptacle and a system of diagnosing the state of the appliance using this method. With the help of an UHF antenna placed in the receptacle of the appliance, the method consists of analysing the spectrum (RS1) of the electromagnetic signal picked up by the antenna and of identifying within the spectrum one or more frequencies of interest (B1, B2), for each of which the signal has an amplitude greater than a predetermined threshold value. To identify the frequency/frequencies of interest, the spectrum of the signal received by the antenna is compared with a reference spectrum (RS2).

Granted: 2012-05-29
Abstract: The two plates (2, 3) have the same corrugated profile and are fixed together in linking zones defining a plane of symmetry (P) for the tubes (4) defined by the plates. The crests and valleys of the corrugations are inclined with respect to a first edge of the plate by a non-zero angle and which surrounds with the other plate inclined decantation tubes : The angle of inclination alpha is between 45 and 65 degrees., preferably between 55 and 60 degrees. The crests and valleys are trapezoidal in form so the decantation tubes have a hexagonal section. The crests (2A, 3A) and valleys (2B, 3B) have identical shapes and the two plates are symmetrical with one another about the plane of symmetry of the tubes. The two plates are identical and are rectangular, with the tubes rectilinear over their whole length. An independent claim is made for a decantation block made of several plates of which at least one pair are as described above. The block has at least two modules joined together so the modules together define other tubes of the same section as the tubes in each module. The modules are identical. The block is in the form of a rectangular parallelepiped, with the plates parallel to one of the faces of the block. The plates extend perpendicular to the smallest dimension of the block and the block is arranged so that the plates are vertical and the first edge horizontal. The block has seating elements by which the block can be held suspended from or rested on a fixing system. At least two identical blocks can be juxtaposed so the tubes of one block are the extension of the tubes in the other. The block is placed near a vessel wall to which the plates are perpendicular, leaving a space between the wall and the block. The tubes have a hydraulic diameter of between 40 and 100 mm and their length is between 15 and 30 times their diameter.

Granted: 2014-04-15
Abstract: Methods and apparatuses for detecting radial flows of conductive fluid are provided. In an embodiment of the present invention, shields are used to prevent or reduce circulating electrical currents from causing a voltage difference that would adversely affect the measured voltage difference between two adjacent electrodes. The shields may be a conduit through which conductive fluid may flow. Groups of sensors, e.g., two or more, may be placed within the shield. The shields may have any cross-section shape. Generally, once the circulating electrical current flow between the electrode pairs is substantially reduced or eliminated, only the voltage difference from the localized induced electric field remains. This way, a true induced voltage may be measured, and thus an accurate value for the fluid velocity may be determined.

Abstract: A mobile station has a processor and a user input mechanism such as a button that is operable to cause the processor to extract at least one feature from a digital media sample. The feature, such as a spectral centroid, is descriptive of an identity of a content of the media sample. Preferably, the same user input that causes the feature extraction also causes a transmitter to establish a link and to send a message to a network address, the message having a plurality of extracted features from which the digital media sample may not be reconstructed. Where a reply message identifies a media file that matches the media sample, another user input at the same or a different button causes an authorization message to be sent so that a copy of the media file, identified in the reply message and having features that exactly match the plurality of extracted and transmitted features, is downloaded to the mobile station.
