Title: Procede et dispositif pour detecter des ondes electromagnetiques partant d'une masse en fusion
Inventor: FRITZ ERNST
IPC: G01N33/20
Filed: 1996-12-19
Abstract: Selon un procédé pour détecter des ondes électromagnétiques partant de l'intérieur d'une masse en fusion (3), notamment d'une masse métallique en fusion, on forme une cavité (26) remplie de gaz dans la masse en fusion (3) en y insufflant du gaz. On observe et on évalue les ondes électromagnétiques qui sont émises par la masse en fusion (3) et qui traversent le gaz insufflé en dirigeant les ondes électromagnétiques vers un détecteur (22), par l'intermédiaire d'un système optique (20), afin de déterminer la température et/ou la composition chimique. Pour éviter toute altération des valeurs mesurées, les ondes électromagnétiques émises sont débarrassées des ondes électromagnétiques dirigées obliquement par rapport à l'axe optique (38) du système optique (20) et présentes en dehors d'un rayon limite (41) tiré depuis l'axe optique (38) du système optique (20), cela en faisant dévier ces ondes électromagnétiques de l'axe optique (38) dans un dispositif de dispersion des ondes (42) du système optique (20), seules les ondes électromagnétiques quasiment parallèles à l'axe optique (38) du système optique (20) venant alors frapper un détecteur (22) implanté en aval du système optique (20), et/ou en déplaçant le système optique (20) pour aligner son axe optique (38) par rapport à la cavité (26) jusqu'à ce que l'intensité des ondes électromagnétiques émises donne une valeur maximale lors de son évaluation.

Title: Dual clutch reverser actuating mechanism
Inventor: HAMBY GLENN MARKHAM
IPC: F16H63/08
Filed: 1998-12-09
Abstract: A dual clutch forward/reverse unit includes a pair of spring engaged clutch units and a pair of lifter pins, each pin operable to disengage a corresponding one of the clutches. An actuator mechanism for the forward/reverse unit includes a housing, a shaft rotatably mounted in the housing, and a hollow cylindrical sleeve rotatably mounted on the shaft. The shaft and the sleeve are operatively coupled to the lifter pins. The shaft has a pair of cam surfaces formed on an outer periphery thereof. The sleeve has a pair of openings through which the cam surfaces are exposed. A pair of lifters are pivotally supported in the housing. Each lifter has one side engaging a corresponding one of the lifter pins, and has another part engagable with one of the cam surfaces through a corresponding one of said openings. Each cam surface is thus operatively coupled to one of the lifter pins by a lifter. The sleeve is rotatable to a position wherein a wall of the sleeve acts to uncouple the lifters from the shaft so that the shaft can be rotated while both clutches are disengaged. The shaft is then rotatable to selectively engage one or the other of the clutches.

Title: Coin validation apparatus
Inventor: HEATHERSHAW EUGENE GRAY
IPC: G07D3/12
Filed: 1997-07-29
Abstract: A coin validation mechanism for evaluating coins and the like inserted therein and for validating acceptable coins includes a coin chute defining a coin path and a sensor for evaluating the type of material of which the object in the coin chute is made of. The sensor for evaluating includes a coil sensor positioned adjacent the coin path and a non-resonant electrical circuit for operation of the coil sensor. The coin validation mechanism also includes a light source for directing light across the coin path and a light sensor for sensing light directed across the coin path. An electronic unit is provided for evaluating an electromagnetic pertubation caused by an object moving past the coil sensor and for determining the amount of light blocked by the object in the coin path by comparing the amount of light sensed by the light sensor with the object in the coin with the amount of light sensed by the light sensor in the absence of an object in the coin path. The electronic unit further compares the amount of light blocked by the object in the coin path and the electromagnetic pertubation with known values for valid coins to evaluate whether the object in the coin path is a valid coin or not.

Title: Composite joint configuration
Inventor: EHRLICH RODNEY P
IPC: B62D25/02
Filed: 1999-03-17
Abstract: A sidewall of a trailer is formed from at least two composite panels joined together by a novel joining configuration. Each panel is formed from inner and outer thin metal skins and a plastic core sandwiched between the skins. In several embodiments, at least one of the skins has at least one end coined to as to compress the core between the skins to define a coined end section. A logistics plate and a splicing member are used to join the panels together and are secured thereto by rivets.      The logistics plate and/or the splicing member may sit against the coined end sections. The splicing member may have flat top and bottom portions to facilitate in the attachment of the panels to the top and bottom rails of the trailer. In other embodiments, a logistics plate is secured by rivets to the panels for joining them together. The splicing member is eliminated and instead, the outer skin of at least one panel is extended to lie behind the logistics plate. In yet another embodiment, the inner skin may have rolled or formed grooves to provide a smooth transition from a logistics plate having rolled edges. An insert may be used between the skins where the rivets are inserted in any of the embodiments to substantially prevent compression of the panels.

Title: Transform domain image watermarking method and system
Inventor: RICHARDSON THOMAS J
IPC: G06T1/00
Filed: 1999-04-22
Abstract: A method and system for watermarking and recovering a watermarked digitized image for subsequent authentication. The digitized image comprises spatial domain data signals reproduced from an original image. A transformer transforms the spatial domain data signals into frequency domain data signals, including respective magnitude and phase data signal components. Information is embedded into the magnitude data signals to develop modified data signals and the modified data signals are converted from the frequency domain to the spatial domain to generate the watermarked digitized image. For recovery, a second transformer transforms the spatial domain data signals comprising the respective original digitized image and watermarked digitized image into respective frequency domain dataset signals. A comparator responsive to the two transformer outputs compares the respective frequency domain dataset signals to identify the watermark and verify the authenticity of the image reproduction.

IPC: A61M25/00
Filed: 1998-01-20
Abstract: L'invention concerne un système permettant d'accéder à une lumière corporelle par l'intermédiaire d'une canule d'accès distal et d'une canule d'accès proximal. La canule d'accès distal est fixée à la lumière corporelle ou placée à l'intérieur de celle-ci, la canule d'accès proximal étant reliée à une chambre à injection implantable ou disposée sous la peau avant d'être fixée à une seringue Luer ou à tout autre raccord extérieur. Ces canules d'accès distal et proximal sont généralement implantées séparément, coupées dans le sens de la longueur, et fixées l'une à l'autre sous la peau. De préférence, la lumière dans laquelle est destinée à s'introduire la canule d'accès proximal présente un diamètre supérieur à celui de la canule d'accès distal, ce qui permet de réduire la résistance vasculaire à l'intérieur desdites canules. Les canules d'accès distal et proximal peuvent parfois former une seule canule.
