Filed: 1999-04-01
Abstract: A telepresence system (100) uses an array of cameras (14) to provide a first user (22-1) with a first display (24-1) of an environment and a second user (22-2) with a second display (24-2) of the environment. Each camera has an associated view of the environment. A first user interface device (24-1) has first user inputs associated with movement along a first path, and a second user interface device (24-2) has second user inputs associated with a second path. A processing element interprets the first and the second inputs and independently selects output of the cameras (14), allowing the first user (22-1) and the second user (22-2) to navigate simultaneously and independently through the environment.

Title: Fuel cell system shutdown with anode pressure control
Inventor: CLINGERMAN BRUCE J
IPC: H01M8/04
Filed: 2000-12-05
Abstract: A venting methodology and pressure sensing and vent valuing arrangement for monitoring anode bypass valve operating during the normal shutdown of a fuel cell apparatus of the type used in vehicle propulsion systems.      During a normal shutdown routine, the pressure differential between the anode inlet and anode outlet is monitored in real time in a period corresponding to the normal closing speed of the anode bypass valve and the pressure differential at the end of the closing cycle of the anode bypass valve is compared to the pressure differential at the beginning of the closing cycle. If the difference in pressure differential at the beginning and end of the anode bypass closing cycle indicates that the anode bypass valve has not properly closed, a system controller switches from a normal shutdown mode to a rapid shutdown mode in which the anode inlet is instantaneously vented by rapid vents.

Title: Apparatus for use in a pipe bending machine and method for bending pipe
Inventor: DUNN CHRISTOPHER F
IPC: B21D11/00
Filed: 2000-12-15
Abstract: A pipe bending machine, a segmented bending die for use in a pipe bending machine, and a method for bending pipe are disclosed. The pipe bending machine includes a frame, a segmented bending die, a support structure, a stiffback, and a pin up shoe. A pipe is inserted in the pipe bending machine, over the pin up shoe, between the segmented bending die and the support structure, and onto the stiffback. By raising the stiffback upwardly and securing an end of the pipe with the pin up shoe, the pipe is bent against the segmented bending die. The segmented bending die and the support structure conform to the external surface contours of the pipe to support the walls of the pipe, thereby preventing distortion, buckling, flattening, or collapsing of the pipe during bending.

Filed: 1999-05-27
Abstract: Un écran de projection (30) pour la visualisation d'images par rétroprojection comporte plusieurs éléments opto-holographiques (10) disposés dans un plan. Ces éléments opto-holographiques sont éclairés par un projecteur (14) possédant trois systèmes de projection (22, 24, 26). Chaque système de projection (22, 24, 26) produit un faisceau lumineux (16, 18, 20) contenant respectivement les extraits de couleur d'une image à projeter. Chaque élément opto-holographique (10) comporte au moins une lentille et un réseau de diffraction permettant de diffracter les différents faisceaux lumineux (16, 18, 20) de telle manière que l'élément opto-holographique (10) délivre un faisceau de sortie lumineux (28) présentant le même angle de sortie (.beta.) en direction d'un observateur (12). Avec un tel écran de projection, la lumière dispersée est très faible, de sorte que l'écran de projection peut s'utiliser également avec la lumière du jour et pour des projections d'image sur grande surface.

Abstract: L'invention concerne un procédé permettant de récupérer un flux de gaz à haute pression riche en hydrogène dans un gaz de purge issu d'un hydrotraiteur. Pour former un mélange gazeux, ce flux de gaz de purge est mélangé à un gaz de synthèse qui constituait la principale source d'hydrogène. Pour un meilleur résultat, ce gaz mélangé constitué de gaz de purge et de gaz de synthèse est traité afin d'en éliminer les gaz acides et d'autres impuretés éventuelles. Le gaz mélangé est ensuite traité afin d'en extraire un gaz riche en hydrogène et un gaz pauvre en hydrogène au moyen, par exemple, d'une membrane. Au moins une partie du gaz riche en hydrogène est ensuite chauffée et comprimée selon qu'il sera nécessaire, puis elle est remise en circulation dans l'hydrotraiteur.

Title: Gas discharge lamp and associated method of production
Inventor: ILMER MICHAEL
IPC: H01J61/36
Filed: 2000-07-28
Abstract: A gas discharge lamp having a discharge vessel, for example composed of a base plate, front plate (2) and frame (3), has at least one closure element (6) which closes a discharge vessel opening in a gas-tight fashion by virtue of the fact that the closure element (6) was inserted into the discharge vessel opening and subsequently fused. The closure element (6) consists of a material which is low-melting by comparison with the remainder of the discharge vessel, for example sintered glass. It is possible to dispense with an additional connecting means between the closure element (6) and the adjacent wall of the discharge vessel (2).

Abstract: In-line manual razor blade shaving devices (1000, 1200) feature an elongated frame (1002, 1202) having an elongated front cutter support portion (1004, 1204) arranged in-line with an elongated handle portion (1006, 1206). The cutter support portion has first and second opposed sides upon which elongated razor blade structures, such as dual razor blade cartridges (1010, 1012, 1210, 1212), are mounted. The elongated razor blade structures each feature at least one razor blade strip (1022, 1324) spaced from and arranged generally parallel to elongated front (1008, 1344) and rear (1014, 1016, 1316, 1318) guard portions. The guards define a working plane (1344, 1346) into which the razor blade edges (1066, 1336) of the razor blade structure project. The new in-line safety straight razors of the present invention may be utilized in a manner very much like the old unguarded in-line straight razor devices long used by barbers, except that front and rear guard portions help shield the exposed razor-sharp edges so as to minimize the occurrence of minor cuts, nicks and scrapes.

Abstract: An exterior automotive trim product, and method of making the same. In certain embodiments, a color pigmented thermoplastic layer (75) is provided. A transparent clear coat (77) is calendared to the color pigmented layer (75) to form a composite or laminate. The laminate is subsequently vacuum-formed into a three dimensional shape approximating the desired shape of a final trim product.  The vacuum-formed laminate (91) is then inserted into an injection molding device, and semi-molten resin (119) injected into the mold cavity behind the laminate (91). The resin fuses with the vacuum-formed laminate (91) with the result being the final automotive trim product. Thus, no spray painting or spraying of solvents is required, and burdensome dry paint transfer techniques may be avoided.

Abstract: A snap-in, tamper proof LED lamp includes a lens and a rear housing and can be easily installed within a aperture of a vehicle. The real housing of the LED lamp provides flexible tabs which are compressed as the lamp is mounted. If upon mounting the flexible tabs are accessible, a ring shaped lock can be affixed to prevent compression of the tabs and therefore prevent removal of the lamp from the aperture. Recesses are provided between the lens and the housing. If an attempt is made to remove the LED lamp from the aperture without depressing the tabs, the recesses cause the lens of the LED lamp to break. The irreparable damage caused to the LED lamp serves to deter future attempts to steal the LED lamps.
