Abstract: La présente invention concerne un équipement (14) de commande et de fourniture d'un retour de force par l'utilisation d'un appareil d'interface manipulé par un utilisateur et relié à un système informatique hôte (12). Un microprocesseur (26) est fourni localement à l'appareil d'interface et lit les données provenant de capteurs, et qui décrivent le positionnement d'un objet déplacé par l'utilisateur, comme un manche à balai. Le microprocesseur commande des vérins (30) pour donner des forces sur l'objet manipulé par l'utilisateur. L'ordinateur hôte envoie des ordres hôtes de niveau élevé au microprocesseur local, qui exécute de manière indépendante un processus reflex local fondé sur l'ordre de haut niveau, afin de fournir des valeurs de forces à des vérins, en utilisant les données des capteurs et d'autres paramètres. Un protocole d'ordres hôtes comprend différents types d'ordres hôtes et de paramètres d'ordres correspondants. En outre, en fournissant un ensemble relativement restreint d'ordres hôtes de niveau élevé, le protocole transfère la charge de calcul de l'ordinateur hôte au microprocesseur local.

Abstract: In a blow-molding system in which a parison programmer is coupled to orifice tooling in an extrusion die head for controlling wall thickness of an extruded parison fed to a blow-molding apparatus, a method of synchronizing operation of the parison programmer contemplates placement of observable indicia on the parison after the parison exits the die head. This indicia placement preferably is carried out under control of the parison programmer to place the indicia at a predetermined position along the parison profile, such that mis-positioning of the indicia indicates absence of phase synchronization of the parison programmer. The indicia is then observed on a molded article to determine phasing of the parison programmer relative to the molding apparatus, and operation of the parison programmer is adjusted to correct any mis-positioning. In the preferred implementation of the invention, the readable indicia comprises an optically readable spot or dot, and position of this spot or dot on the molded article is determined by an optical sensor that provides an electrical signal for automatic closed-loop correction of parison programmer phasing without operator intervention.

Title: Optical fiber connector using fiber spring force and alignment groove
Inventor: LEE NICHOLAS A
IPC: B08B7/00
Filed: 1996-12-23
Abstract: A fiber optic connector comprising a plug and a receptacle uses the spring force supplied by bowing of the plug fiber to maintain a continuous compressive load at the fiber joint located in a fiber-alignment groove. The plug has a holder for securing the plug fiber and a shroud which snaps onto the holder with the plug fiber extending generally straight inside the shroud.  The shroud has a slot providing access to the terminal portion of the plug fiber, and a sliding door which selectively covers the slot. The receptacle includes a housing and another fiber holder for securing the receptacle fiber, with a projection or finger attached to the receptacle fiber holder, the projection having the fiber-alignment groove. The finger is oriented within the receptacle housing such that, when the plug is inserted into the receptacle, the finger extends through the slot in the shroud at an oblique angle with respect to the plug axis. In this manner, as the plug is inserted, the end of the plug fiber slides into the fiber-alignment groove in the finger and comes into contact with the end face of the receptacle fiber. Continued insertion results in bowing of the plug fiber to achieve the compressive load.  The plug door may have camming surfaces which are actuated by corresponding surfaces on a door of the receptacle. The connector may be used to simultaneously interconnect a plurality of fiber pairs, or to terminate a fiber to an active optical device.

Abstract: The time division multiple access (TDMA) frame time synchronization error for received mobile station burst communications transmitted on the reverse digital control channel is monitored by the receiving base station (14). A probability density function (62) is then prepared by the base station reflecting the number of instances of each determined length of time synchronization error monitored over a predetermined time period. The probability density function is then processed to identify the percentage of burst communications during that predetermined time period that exceed (76) a synchronization error threshold (64). If the determined percentage exceeds a given percentage, then abbreviated length burst communication operating mode (70) is ordered by the base station for all mobile stations operating within the cell.      Otherwise, conventional length burst communication operating mode (72) is ordered by the base station.      The measured time synchronization error is continuously processed to effectuate dynamic control over the specified length of mobile station burst communications.

Abstract: The present invention includes a small diameter explosive cartridge and a two-stage large diameter explosive cartridge apparatus for presplitting rock can be axially detonated by detonating cord through a central detonation passageway in the explosive cartridge while keeping the detonating cord and the explosive material in the explosive cartridge physically separate. The explosive cartridge includes an outer tube and an inner tube inside of the outer tube. The explosive cartridge includes two or more continuous webs extending radially between the outer surface of the inner tube and the inner surface of the outer tube. For the small diameter explosive cartridge, the space between the outer surface of the inner tube and the inner surface of the outer tube is filled with high explosive material such as water gel or emulsion explosive material. The inside of the inner tube forms a central detonation passageway axially through the small diameter explosive cartridge through which detonating cord can be strung to provide axial detonation and to provide effective detonation between each of the small diameter explosive cartridges when the small diameter explosive cartridges are assembled on a line of detonating cord in a borehole, while keeping the detonating cord and the emulsion explosive material in the small diameter explosive cartridge physically separate. The two-stage large diameter explosive cartridge apparatus includes a large diameter explosive cartridge and a small diameter explosive cartridge. The construction of the large diameter explosive cartridge is similar to the small diameter explosive cartridge but of a larger scale so that the small diameter cartridge can slide into the central primer passageway of the large diameter explosive package. For the large diameter explosive cartridge, the space between the outer surface of the inner tube and the inner surface of the outer tube is filled with blasting agent material. The small diameter explosive cartridge then acts as a primer to initiate the large diameter explosive cartridge.
