Abstract: A system and method in an H.323 network for automatically reestablishing signaling that was interrupted due to gatekeeper failure. Primary and secondary gatekeepers (104a, 106a) establish a supervisory link (1b) with one another while the media connection is set up between client terminals (112a, 114a). The primary gatekeeper (104a) also establishes the H.225/H.245 signaling between the client terminals. If the primary gatekeeper (104a) fails, the H.225/H.245 connections go down, but the media connections will continue. The secondary gatekeeper (106a) than takes over the call and sends a message to its zone's clients that the H.225/H.245 connections need to be reestablished. Further, the secondary gatekeeper (106a) sends a message to the other zone's gatekeeper (if any) of what has occurred. The clients then reestablish the H.225/H.245 channel by using the original setup message with a new Reestablish parameter.

Abstract: A requirement of a replaceable component to print a print job at a printing device is derived from a predetermined use per page of the replaceable component at the printing device. If an availability of the replaceable component at the printing device is less than the requirement, a diagnostic is output. The requirement and the availability are approximations expressed in a number of pages.

Abstract: A thin film transistor with a channel less than 100 angstroms thick, preferably less than 80 angstroms thick, preferably less than 60 angstroms thick. The very thin channel reduces variability of threshold voltage from one TFT to the next. This is particularly advantageous for TFT memory arrays. It is possible that an extremely thin channel restricts the size of grains, forcing many small grains to be formed.

Abstract: A work pallet for processing optical fiber. The work pallet may be configured to manage lengths of optical fiber for an automated manufacturing process. In this regard, the pallet may be configured to organize and maintain individual fibers in one or more desired positions to facilitate a manufacturing process. For example, the pallet may be employed for an automated fusion splicing process in which pairs of optical fibers are spliced to each other to establish an optical circuit. The pallet presents a platform on which corresponding fibers of an optical fiber module or other device may be arranged in an organized fashion for fiber preparation, fusion splicing, fiber recoating, post-processing storage and the like. The pallet may employ a cross-lacing arrangement in which the fibers extend in opposite directions across the pallet to control fiber slack associated with subsequent fusion splicing or other processing of the fiber pairs.

Abstract: A vehicle occupant sensing system includes a laser array that generates three beams. A first beam is directed toward an upper body zone, a second beam is directed toward a middle body zone, and a third beam is directed toward a lower body zone. A first sensor assembly receives reflection beams from the upper body zone and generates a first signal that represents a proportional amount of an occupant present in the upper body zone. A second sensor assembly receives reflection beams from the middle body zone and generates a second signal that represents a proportional amount of the occupant present in the middle body zone. A third sensor assembly receives reflection beams from the lower body zone and generates a third signal that represents a proportional amount of the occupant present in the lower body zone. The laser array and the first, second, and third sensor assemblies are all mounted within a common housing that is mounted to a vehicle structure such as an A-pillar or rear view mirror.

Abstract: The method enables an improved and faster error recognition of software errors in a processor or processor system in which programs subject information received from other programs to an error check, particularly to a plausibility check, and, given acquisition of error statuses, output a corresponding error message to the operating system. This error message contains an indication of the other program generating the faulty information and is stored in a respective error message table. The operating system thus learns of programs suspected of working in a faulty way from other programs collaborating with these programs, so that program errors can be recognized and localized significantly faster.

Abstract: Endpoints, such as clients and gateways, maintain local codec priority lists (500), receive remote codes priority lists (504), and maintain common communication attribute priority lists (502). When opening a transmittal channel, a local endpoint determines the highest priority codec on its local priority list (500) that is also on the remote priority list (504). The local endpoint also determines the highest priority codec on the remote priority list (504) that is also on the local priority list (500). If the codes types match, then the transmitting channel is opened with that codec. If there is no match, then the common communication attribute priority list (502) is used, and the local or remote codec that has a corresponding highest or lowest desired attribute is used for the communication.

Abstract: The specified monitoring program enables the recognition of endless loops or blocked processes in a computer system, in particular in a telecommunication switching system. When such software errors are recognized, error indices can be collected and stored, which enable a later error analysis and removal. The endless loops or, respectively, blocked processes can also be reset in a suitable way, so that no negative effects on other processes result.

Abstract: A process for upgrading aqueous acrylonitrile waste streams containing organic material comprising atomizing an acrylonitrile waste water stream containing organic material, introducing the atomized acrylonitrile waste water stream at a temperature below the decomposition temperature of the organics present in the waste water stream, into a reaction zone containing a catalyst and at least one reactant gas, reacting the atomized waste water stream and reactant gas in the presence of the catalyst to convert at least some of the organics in the waste water stream into at least one compound selected from the group consisting of acetonitrile, hydrogen cyanide and acrylonitrile.

Abstract: In an HF alkylation process where an acid catalyst regeneration column separates HF acid from ASO and water to provide regenerated catalyst for a catalyst circulation stream, and where buildup of ASO in the catalyst circulation stream is encountered, an improved control scheme uses an on-line analyzer/controller to maintain desired concentrations of HF acid, or ASO or water in the catalyst circulation stream. In one embodoment, a continuously flowing catalyst slip stream is piped to the analyzer/controller for simultaneously determining concentration of HF acid, ASO and water, and in a preferred embodiment the ASO concentration is maintained at a desired low level by manipulating temperature of a stripping fluid charged to a lower section of the column. An alternate manipulated variable is temperature of the acid catalyst feed to the regenerator column. Alternate controlled variables are the HF acid, and water concentration in the catalyst circulation stream.

Abstract: In a telecommunication network of ATM exchanges (V1, Vn) via which information transmitted in the STM mode can also be switched, error-detecting code words (EDCE) are respectively derived at an exchange input (EVi) from the content of information parts (PL) of a defined plurality of ATM cells in order to monitor the through-connections through an exchange. These error-detecting code words (EDCE) are transmitted to an exchange output in transition monitoring cells (DUZ) together with the plurality of information parts (PL) and are compared thereat to a newly formed error-detecting code word.

Abstract: A method and system for executing an application at a client are described. An application is divided into portions. A first portion of code for the application is transmitted to the client over a network. The first portion of code is executed at the client to cause the client to generate a user interface that is displayed by the client, detect user interaction with the user interface, and transmit from the client over the network messages that indicate the user interaction with the user interface. A second portion of code for the application is executed at a node of the network other than the client. The second portion of code causes the node on which it is executing to respond to user interface messages from the client by (1) generating records that indicate changes to the user interface, and (2) transmitting the records to the first portion of code. The first portion of code responds to the messages by performing the specified changes to the user interface.

Abstract: The program system of a complex computer system is highly customer-specific, for which reason the start-up varies considerably. The start-up system of such a computer system must therefore be very flexible. On the other hand, however, early and close monitoring of the complex start-up should be ensured. These requirements are satisfied by a start-up system which has a start-up table generated off-line.
