Title: Telecommunications switches and methods for their operation
Inventor: NICHOLS STACY S
IPC: H04Q11/04
Filed: 2000-07-27
Granted: 2007-12-04
Abstract: A telecommunications switch for switching protocol data units across communications links connecting the switch into a communications network and supporting multiple service types concurrently is disclosed. The switch includes an ingress processor for receiving protocol data units from a communications link, an egress processor for transmitting protocol data units onto another communications link, and a switching fabric for routing protocol data units from the ingress processor to the egress processor. The switch includes a structure of queues and schedulers that is arranged to provide concurrent class-based and flow-based queuing and scheduling of the protocol data units. This arrangement allows an amount of switching bandwidth to be guaranteed to protocol data units belonging to a given flow and allows classes of service within the flow to be allocated a relative proportion of that bandwidth. The structure is re--configurable in its interconnection of queues and schedulers via a link list in which pointers to the queues and schedulers are stored and updated as required.

Abstract: A system and method implemented in an interactive television system for managing modules of interactive television applications. The system transmits modules from a broadcast station to a plurality of receiving stations through various paths, such as broadcast channels and modem channels. The receiving stations have module managers which store module requests and which monitor the various channels for modules corresponding to the requests. When modules are transmitted on the monitored channels, they are matched with the corresponding stored requests. If a module matches one of the requests, or if it is an auto-loading module, it is stored in the receiving station. If a module has not been requested and is not an auto-loading module, it is ignored. The stored modules are added to a list of modules available for execution or for use by an executing application, and the corresponding requests are deleted.

Abstract: A method and system for providing configurable data services for mobile stations allows mobile stations to select the type and content of data messages addressed to a mobile station. The method includes establishing an active profile associated with a corresponding mobile station. A wireless data server receives a data message addressed to the mobile station. The active profile for the mobile station is accessed to determine applicable stored profile attributes for the mobile station to which the received data message is addressed. The wireless data server detects received profile attributes associated with the received data message. Filtering is applied to the received data message in real-time based on a comparison between the detected profile attributes and the stored profile attributes. The detected profile attributes are readily standardized in accordance with standards followed by the content service provider in order to gain access to the mobile service subscribers.

Abstract: An improvement in dead lever lugs for mounting on cast metal bolsters for railway trucks is disclosed. The bolster has two side walls. The side walls have angled portions that meet in radii along the junctures of the angled portions, The dead lever lug has two arms joined by a bridge section. Each of the arms has a mounting surface that is shaped to mate with the shape of one of the angled surfaces of the bolster. The mounting surfaces of the dead lever lug arms are separated by a gap. When the dead lever lug is mounted on the bolster, the dead lever lug straddles the juncture of the angled portions of the side wall. One mounting surface of each arm is positioned against one of the angled portions of the side wall and the gap overlies the juncture of the two angled portions of the side wall. With the dead lever lug of the present invention, no flat raised mounting area is needed on the side wall of the bolster.

Abstract: Noise reduction sandwich panel, notably for an aircraft turbojet engine. In order to produce a noise reduction sandwich panel having a structure with two degrees of freedom, inserted separative components (20) are placed into the hexagonal cells (16) of the unique waffle core of the panel. More specifically, the separative components (20) have an substantially circular external peripheral edge, which allows them to be easily assembled, in spite of the deformations of the walls (18) of the cells (16) due to manufacturing tolerances and to the optional forming of the waffle core. Advantageously, several separative components (20) are supported by a same positioning unit (22), which then allows relative displacement between the separative components.

Title: Optical disk and optical disk reproduction apparatus and recording apparatus
Inventor: WATANABE ATSUSHI
IPC: G11B7/24097
Filed: 2001-12-28
Granted: 2012-03-13
Abstract: An optical disk includes a feature forming area 11 and a criterion recording area 12. The feature forming area 22 is an area provided with physical features used for determining whether it is an authorized optical disk or not. The criterion recording area 12 is an area having recorded therein the data of a determination criterion, i.e., a criterion by which it is determined whether the optical disk has been produced in an authorized manner or not on the basis of the physical feature. An optical disk reproduction apparatus detects the physical features provided in the feature forming area 11, and reads the determination criterion recorded in the criterion recording area 12. Furthermore, based on the determination criterion which has been read, the optical disk reproduction apparatus determines whether or not the detected physical features are those provided for an authorized optical disk. Thus, the optical disk reproduction apparatus can determine whether or not the optical disk has been copied in an unauthorized manner.

Title: In vacuo glycation of proteins
Inventor: KAPLAN HARVEY
IPC: C07K1/107
Filed: 2002-08-15
Granted: 2012-07-17
Abstract: It has been discovered that facile glycation of proteins can be achieved by colyophilization of a protein with a reducing sugar, subjecting the lyophilized mixture to a vacuum (10 to 50 millitor) and incubating at an elevated temperature (50 to 100°C) for 1 to 24 h. A stable ketoamine derivative is formed with amino groups in the protein and no advanced glycation end products (browning reaction) are observed, as is the case with aqueous glycation procedures. Another novel feature is that the in vacuo glycation reaction takes place with the protonated amine and not the deprotonated amine as is believed to be the case for aqueous glycation reactions. Advantage can be taken of the in vacuo glycation reaction to achieve facile covalent cross-linking of proteins by lyophilizing protein or proteins with compounds containing two or more reducing sugars separated by a linker.

Abstract: In a first standby state, the reception quality of a signal from a system which has established synchronization is detected. If the detected reception quality deteriorates to be less than a threshold value, the destination of synchronization establishment is changed from a first system to a second system. In a second standby state after this system change, the reception quality of a system having a higher priority order of selection than the second system which has established synchronization is detected. If a third system whose detected reception quality exceeds the threshold value is found, the destination of synchronization establishment is changed to this third system again. After that, the first standby state is returned.
