Title: Tooth bleaching compositions and methods for bleaching discolored tooth
Inventor: HIGASHIIZUMI EMI
IPC: A61K8/29
Filed: 2000-07-03
Granted: 2011-09-06
Abstract: The bleaching compositions of discolored teeth comprise titanium dioxide initiating photocatalyst action with light irradiation, chemical compounds generating hydrogen peroxide in an aqueous solution and thickening agents. Further the bleaching methods of discolored teeth comprising applying the bleaching composition onto the surface area of the teeth and then initiating photocatalyst action by irradiating the applied surfaces area with light. Therefore, the present invention shows remarkable bleaching results due to easy application of the compositions onto discolored teeth and keeping the original activity of the photocatalyst without its deterioration.

Title: Surgical stapling instrument
Inventor: LONGO ANTONIO
IPC: A61B17/32
Filed: 2001-07-17
Granted: 2009-11-24
Abstract: A surgical stapling instrument (1) comprises a frame having a body portion (2) and a handle. A staple fastening assembly (4) is provided in the distal region of the instrument (1) and includes a cartridge device (6), which comprises at least one closed row of staples, and an anvil (8). The anvil (8) is movable relative to the cartridge device (6) and is adapted to cooperate with the cartridge device (6) for forming the ends of the staples exiting from the cartridge device (6). A knife, which has a closed cutting edge, is contained within the cartridge device (6) and is positioned such that there is at least one closed row of staples on the outside of the cutting edge. It can be moved towards the anvil (8). The line defining the closed row of staples has a plurality of indentations such that the line defining the closed row of staples has a larger total length than a circle tangent to the outer perimeter of this line. This provides greater flexibility of the anastomotic site and less tension during instrument removal, alleviating the incidence of clinical complications.

Inventor: LHOMME CHRISTOPHE
IPC: G06V30/10
Filed: 2001-06-19
Granted: 2008-06-17
Abstract: The video-coding station for an installation for sorting postal items, in particular packets, steering each packet towards a sorting outlet on the basis of an automatic reading of a postal address (AD) of the packet in a digitized image of the packet, comprises a central processor unit, a screen (EC), and a keyboard (CL), and is programmed so as to display an image (IP) so that a video-coding operator (OV) can perform semi-automatic processing of the reading of the address (AD). The station further comprises a pointing device (JS) for positioning a reticule (RE) on the center of a zone of the image displayed, and a trigger button (BT) for recording the current position of the reticule so that the operator can rapidly identify the location of the postal address (AD). Such a video-coding station enables an operator to identify rapidly a zone of interest comprising the postal address, so that the postal address corresponding to the packet can be identified by applying an automatic character-recognition algorithm to the zone of interest.

Abstract: A method and apparatus for controlling a lamp ballast having a DC-DC converter with first and second MOSFETs acting as switches alternately connecting a DC power source to a power transformer, with an output of the power transformer being connected to a DC-AC inverter driving the lamp. The first and second MOSFETs in the DC-DC converter are alternately opened and closed at a frequency that is swept repeatedly between predetermined minimum and maximum frequencies. A microcontroller-based feedback element determines instantaneous power consumption by the lamp and controls the MOSFETs through a pulse width modulator to continuously adjust a duty cycle of signals driving gates of the MOSFETs to maintain a desired level of power consumption.

Abstract: 2 In a pay-for-placement search system, the system makes search term recommendations to advertisers managing their accounts in one or more of two ways. A first technique involves looking for good search terms directly on an advertiser's web site. A second technique involves comparing an advertiser to other, similar advertisers and recommending the search terms the other advertisers have chosen. The a first technique is called spidering and the second technique is called collaborative filtering. In the preferred embodiment, the output of the spidering step is used as input to the collaborative filtering step. The final output of search terms from both steps is then interleaved in a natural way.

Granted: 2009-05-26
Abstract: This invention provides multi-layered composites, laminates and composite joints in which at least one resin-impregnated, fiber-containing layer is joined or laminated to a core layer having a lower flexural modulus or higher elongation at break, higher toughness, or a combination of all or some of these properties. The multi-layer composite produced by laminating or joining these materials together has improved shearout, impact and cutting resistance, since stresses caused by outside forces can be more widely distributed throughout the composite.

Abstract: The invention relates to calcium phosphate composite layers which are electrochemically deposited on bone implants. Implants which are coated in such a way are implanted without cement and are characterised by improved growing-in behaviour. Said highly porous composite layers on implants are made of at least two calcium phosphate phases of different solubility. The highly porous structure of said layers facilitates the immobilisation of cells from which new bone tissue can be made. The different solubility of the individual layer components ensures local concentration of calcium and phosphate ions which accelerates the incorporation process and which adapts to said process over the course of time.
