Title: Large vocabulary connected speech recognition system and method of language representation using evolutional grammar to represent context free grammars
Inventor: BROWN MICHAEL K
IPC: G06K9/52
Filed: 1994-11-22
Abstract: A method of recognizing speech input selectively creates and maintains grammar representations of the speech input in essentially real time. Speech input frames are received by a speech recognition system. Grammar representations are created foreach speech frame and a probability score is derived for the representations indicating the probability of the accuracy of the representations to the speech input. Representations having a probability score below a predetermined threshold are not maintained. Those grammar representations having probability scores above the predetermined threshold are maintained. As more speech frames are received by the system, additional grammar representations are created and the probability scores are updated. When the entire speech input has been received, the chain of grammar representations having the highest probability score identified as the speech input.

Title: Process for the continuous preparation of 2,2,6,6-tetramethylpiperidine
Inventor: KAMPMANN DETLEF
IPC: C07D295/023
Filed: 1994-12-09
Abstract: The reduction of triacetonamine with hydrazine also succeeds continuously by reactive distillation if the hydrazone is first formed and this is continuously transported to the distillation bottoms comprising a high-boiling solvent and an alkali at the base of a distillation column and the resulting 2,2,6,6-tetra-methylpiperidine is distilled off as an azeotrope.      In this procedure a hydrazine/triacetonamine ratio of 1.5:1 to 2.0:1 is sufficient, in comparison with the conventional synthesis, the product yield being able to be considerably increased (>90 %). Moreover, the amounts of alkali and solvent used can be considerably reduced.

Inventor: BARENS IVOR
IPC: F16H3/00
Filed: 1995-06-01
Abstract: A variable-speed gear mechanism comprises a pinion with spring-biased radial pins and a face gear with an operative face that meshes with the pinion at various meshing radii. The gear has a central part which defines a radially innermost set of part-cylindrical sockets. Each socket has anaxial opening which faces outwardly from the gear face and a lateral opening which faces radially outwardly and through which a pin is received laterally into the socket during meshed operation. A recess extends radially outwardly and in both circumferential direction from the bottom of the lateral opening of each socket, permitting unobstructed movement of a pin to and from the socket. A circular groove may define the required recesses. Its depth at a particular radius may be sufficient to avoid contact between the pins and the face gear thereby providing a neutral function. Meshing structure at a next larger meshing radius may consist of another set of sockets with lateral openings facing radially inwardly. Radial grooves may direct a pin located in a socket of the innermost set to a corresponding socket in the other set as the pinion is moved radially to change gear ratios.

Inventor: SUZUKI HIROSHI
IPC: H04L12/70
Filed: 1995-07-18
Abstract: A network topology discovery method automatically recognizes the physical connection relationships of each ATM switch and each ATM terminal within an ATM network. Each ATM switch and ATM terminal mutually exchanges, by ILMI protocol, port identifiers that identify every ATM port of the ATM switch or ATM terminal as well as network addresses of network management agents that manage the ATM switch and the ATM terminal, to neighboring ATM switches and ATM terminals that are directly connected to its ports. Each ATM switch and ATM terminal stores tables for each of its ATM ports that include port identifiers which indicate the identities of connected ports as wall as the network addresses of the network management agents that manage the neighboring ATM switches and ATM terminals. The ATM switches or ATM terminals automatically recognize the local connection relationships with its neighboring ATM switches or ATM terminals, using a network management system, by accessing connection information and then automatically recognizing the physical connection relationships of each ATM switch and each ATM terminal. The network management system recognizes the configuration within an ATM network, whether the network management system is inside or outside the ATM network, including when a router or existing LAN coexists with the ATM network. The identities of ports connected to each port are recognized, when a plurality of links exist between ATM switches, without requiring the assignment of a respective one of its ATM network management agents to each ATM switch.    Interfaces between ATM switches as well as between an ATM switch and an ATM terminal are also automatically identified.
