Title: Absolute light intensity measurements in laser induced incandescence
Inventor: SNELLING DAVID R
IPC: G01N15/00
Filed: 1999-05-18
Abstract: The invention relates to a method and an apparatus for the determination of particle volume fractions with laser induced incandescence (LII) using absolute light intensity measurements. This requires a knowledge of the particle temperature either from a numerical model of particulate heating or experimental observation of the particulate temperature. Further, by using a known particle temperature a particle volume fraction is calculated. This avoids the need for a calibration in a source of particulates with a known particle volume fraction or particle concentration. The sensitivity of the detection system is determined by calibrating an extended source of known radiance and then this sensitivity is used to interpret measured LII signals. This results in a calibration independent method and apparatus for measuring particle volume fraction or particle concentrations. A modeling process involves a solution of the differential equations describing the heat/energy transfer of the particle and surrounding gas, including parameters to describe vaporization, heat transfer to the medium, particle heating etc. The solution gives temperature and diameter values for the particles over time. These values are then converted to radiation values using Planck's equation.

Title: Database management system and method for conditional conflict serializability of transactions and for combining meta-data of varying degrees of reliability
Inventor: ANFINDSEN OLE J
IPC: G06F17/30
Filed: 1999-01-25
Abstract: A database management system (DBMS) is modified to provide improved concurrent usage of database objects, particularly when the system is executing long lived transactions. A subset of the transactions access database objects using parameterized read and parameterized write access modes. Each transaction using a parameterized write mode of access for a database objet specifies a write access mode, and a write access mode parameter, where the parameter indicates a data reliability classification. Each transaction using a parameterized read mode of access for a database object specifies a read access mode, and a read access mode parameter, where the parameter indicates one or more reliability classifications that are acceptable to the transaction. Whenever a transaction requests access to a specified database object, the DBMS generates a corresponding lock request for the object. If the lock request is parameterized lock request, a corresponding parameterized lock request is generated. A lock manager processes each lock request by checking to see if any outstanding, previously granted lock is a unconditionally conflicting or conditionally conflicting wit the requested lock. A query executer queries requesting access to information stored in the database (or other data processing tasks). The query executer includes annotated nullable logic for evaluating expressions containing at least one annotated value as an operand. The annotated nullable logic includes logic for combining annotated values, for comparing annotated values so as to generate annotated truth values, and for combining annotated truth values in accordance with a predefined set of rules.

Patent CA-2302952-A1 (CA)
Inventor: HOLLER JAN
IPC: H04L12/70
Filed: 1998-09-08
Abstract: There are voice signals from at least two voice sources which are multiplexed by an ATM Adaptation Layer 2 multiplexer (AAL2 MUX) into the same ATM connection after having been processed by a packetizing means such that the AAL2 MUX is presented with assembled AAL2 packets of a suitable periodicity. If the voice data signals are to be compressed, the packetizing means comprises an encoder of a suitable voice codec, e.g. ADPCM, GSM, LD-CELP or CSACELP. The voice encoders may also include means for silence removal. The packetizing means further comprises a packetizer, either separated from the voice encoder, or as a part thereof. The packet releases from the packetizing means are synchronized to occur virtually simultaneously. In this way, the released packets from the packetizing means arrive almost simultaneously at the AAL2 MUX, with the result that an ATM cell may be filled with AAL2 packets well before the expiration of the timer Timer-CU of the AAL2 MUX.

Title: Method and apparatus for providing integral cell payload integrity verification and detecting defective modules in telecommunication devices
Inventor: POULIN ANDRE
IPC: H04L12/56
Filed: 2000-05-17
Abstract: A method for verifying the integrity of data payloads of ATM cells passing through a switching device involves computing a payload integrity verification code for the payload portion of an ATM cell and passing the payload integrity verification code along a data path in a telecommunications device with the ATM cell. The payload integrity verification code may be generated according to any error detection or error correction scheme including CRC, check sum, BIP or the like. In preferred embodiments of the invention, the payload integrity verification code is stored in a portion of the standard ATM cell header which is not used during the period while the cell is passing through the telecommunications device. Preferably the payload integrity verification code is stored in all, or a portion of, the virtual path identifier or virtual connection identifier fields within the standard ATM cell header. In most telecommunications devices the function of the VPI and VCI fields are replaced by a connection identifier field which is appended to the cell while the cell is passing through the telecommunications device.      The invention allows for the immediate identification of cells having corrupted payload data. In preferred embodiments of the invention where the payload integrity verification code applies only to the payload data and wherein there is separate check data applying to the ATM header fields, different actions can be taken on the detection of errors in the ATM cell header and ATM cell payloads respectively.
