Abstract: Ce circuit analogique, destiné à un système de microscope à mise au point automatique, mesure un degré de mise au point d'un objet, directement à partir d'un signal vidéo d'une caméra à dispositif de couplage de charge, du microscope. Ce circuit renvoie ensuite un indice à un ordinateur hôte, dans le but de régler la position de l'objectif du microscope, afin de bien mettre au point l'objet. On obtient la meilleure mise au point en comparant les indices au niveau de plusieurs positions verticales. Le critère adopté pour déterminer le degré de mise au point est dérivé de la distribution d'énergie du spectre du signal vidéo. Ce signal passe à travers un filtre passe-haut, une grille (afin d'enlever les artéfacts du balayage), un conformateur carré et un intégrateur. L'énergie haute fréquence du spectre vidéo est au maximum au niveau de la meilleure mise au point et au fur et à mesure que l'optique supprime la mise au point, la distribution d'énergie se décale vers des fréquences plus basses. Grâce au circuit analogique de l'invention, on obtient une mise au point en temps réel peu coûteuse, ce circuit remplaçant du matériel de traitement d'images en temps réel, spécialisé et plus cher.

Title: Process and device for monitoring the degree of wear of a compression worm conveying plasticized material
Inventor: BACHER HELMUT
IPC: B29C48/74
Filed: 1998-04-20
Granted: 2004-06-22
Abstract: This invention concerns a process for monitoring the degree of wear of a compression worm (8) which conveys a plasticized material, in particular, plastic, against an element that exerts a resistance and is located in a worm housing (4). To this effect, the pressure of the material conveyed is measured at two points disposed at intervals along the direction of travel.     These two points are situated at both sides of a resistance body (12) towards which the compression worm (8) conveys. The difference between the two pressures measured is used to display the degree of wear of the worm (5) and its housing. A device for that purpose has an opening (18) which penetrates the wall (20) of the housing (4) of the worm (5) in the region of its thread or in a region immediately adjacent thereto. An additional opening (19) penetrates the wall of this housing (4); both openings (18, 19) are disposed axially at a distance from each other. A pressure sensor (22, 23) is linked to each opening (18, 19).

Abstract: A retractable roller system has a main channel mounted on the floor of a vehicle into which cargo is to be loaded. A pneumatically actuated bladder is mounted along the bottom of the channel and a roller tray on which a plurality of roller members are rotatably supported is mounted in the channel above the bladder. Flange members extend inwardly from the side walls of the channel at different vertical levels. Flange members extend outwardly at different vertical levels from the opposing side walls of the roller tray. The rollers are raised to handle the loading of cargo by inflating the bladder and lowered to recess the rollers below the level of a cover plate to keep the cargo in a desired location. The cover plate utilizes a minimum number of screws in conjunction with a mating coupler plate and slots and for adjacent units which engage pins on the channel to provide secure retention of the plate yet facilitating ready removal when the roller tray needs to be removed for repair or replacement. Such removal can be readily accomplished by tilting the roller tray sideways to permit the side flanges of the roller tray to clear the side flanges of the channel.

Abstract: An apparatus incrementally reduces pressure in a first volume in response to an increase in pressure in a second volume. A valve body defines a bore that houses a piston and supply and return passages that communicate with first and second ends of the bore, respectively. The valve body also defines a release passage that connects the bore with the first volume and an exhaust passage that connects the bore with atmosphere. An inlet valve opens when pressure in the second volume increases relative to pressure in the supply passage. An outlet valve opens when pressure in the second volume decreases relative to pressure in the return passage. The piston is biased in a closed position against the first end and defines a passageway through which the first and the second ends communicate. When pressure increases in the second volume, the inlet valve opens causing the first end to pressurize and move the piston to an open position in which the release and exhaust passages communicate. This allows the first volume to vent gradually to atmosphere. As the pressure gradually equalizes between the first and second ends via the passageway, the piston returns to its closed position thereby discontinuing communication between the release and exhaust passages so that the first volume is cut off from atmosphere. When pressure decreases in the second volume, the outlet valve opens causing pressure to equalize between the supply and return passages via the passageway and to approximate the pressure in the second volume.

Title: Virtual path asynchronous transfer mode switching in a processing satellite communications system
Inventor: WILLIAMS RHON L
IPC: H04Q11/04
Filed: 2000-09-06
Granted: 2005-11-15
Abstract: The present invention provides a method (100) for virtual path switching of an ATM cell on a processing communications satellite. The method includes establishing a set of VPIs (104), where each VPI is associated with an output port on the satellite. The method also includes establishing a set of VCIs (106), and assigning one VPI and one VCI to an ATM cell (108).      The ATM cell may then be transmitted to, and then received by an input port of the satellite (110). The method also includes determining an associated output port (114), and transferring the ATM cell to that output port (116). The VPI may be divided into a control subfield and a routing subfield, and the associated output port may be determined based on the routing subfield (808). The present invention may also provide for multicast switching (400). For example, the method may include providing at least one multicast routing table (404). The VPI assigned to the ATM cell may be associated with a multicast output port. Thus, the ATM cell may be transferred to that multicast output port (418) and then received at the associated multicast module (420). A multicast group of VPIs may then be determined (422, 424), and the ATM cell may be reproduced several times (426). The reproduced cells may be reassigned with a new VPI from the multicast group of VPIs (428), and the reproduced cells are once again presented to and received by an input port of the satellite (430).

Abstract: An automatically locking bayonet coupling mechanism includes, a linear guide structure (23, 23', 24) for preventing relative rotation between the coupler halves (20, 21), a sleeve (22) rotatably mounted on one of the coupler halves, a spring (27, 28) captured between the sleeve and the coupler half on which it is mounted to generate a torsional force between the sleeve and the coupler half, an L-shaped groove (25) in the other of the coupler halves, and a bayonet pin (26) extending from the sleeve and arranged to engage cam surfaces (42, 44) defined by edges of the groove. As the coupler halves are pushed together linearly, engagement between the bayonet pin (26) and a first (42) of the cam surfaces causes the sleeve to rotate against the force of the spring.  Subsequently, the bayonet pin is caused to engage a second (44) of the cam surfaces that forms a locking ramp. As the sleeve is caused to rotate into a locking position in response to the spring force, the angle of the locking ramp causes the spring force on the bayonet pin and locking ramp to also draw the coupler halves together, and to maintain the axial force that draws the coupler halves together after the bayonet pin comes to rest before the end of the locking ramp.
