Title: System and method for providing interactive audio in a multi-channel audio environment
Inventor: MCDOWELL SAMUEL KEITH
IPC: G10L19/02
Filed: 2000-11-02
Abstract: DTS Interactive provides low cost fully interactive immersive digital surround sound environment suitable for 3D gaming and other high fidelity audio applications, which can be configured to maintain compatibility with the existing infrastructure of Digital Surround Sound decoders. The component audio is stored and mixed in a compressed and simplified format that reduces memory requirements and processor utilization and increases the number of components that can be mixed without degrading audio quality. Techniques are also provided for "looping" compressed audio, which is an important and standard feature in gaming applications that manipulate PCM audio. In addition, decoder sync is ensured by transmitting frames of "silence" whenever mixed audio is not present either due to processing latency or the gaming application.

Patent CA-2397316-A1 (CA)
Title: Data recording system
Inventor: NISHINA MASATOSHI
IPC: B60R16/02
Filed: 2002-08-09
Abstract: Abnormality detection is conducted with respect to data indicative of operating state of an apparatus, the abnormality type is then discriminated and a check is made as to whether the data are already recorded in association with the discriminated abnormality type in a memory region corresponding to the data, and if not, the data are recorded in association with the discriminated abnormality type there. Since, multiple recording of similar data related to transient abnormalities and other such events that are likely to occur repeatedly can be prevented, important data related to a diversity of abnormalities and failures can be efficiently recorded in the memory. Viewed from another angle, this means that the capacity of the memory can be reduced and that a cost-reducing effect can be anticipated. In addition, data important for troubleshooting abnormalities and failures, most notably transition period data, can therefore be efficiently recorded in the memory.

Filed: 2001-06-05
Abstract: Cette invention se rapporte à un procédé en temps réel servant à maintenir la stabilité d'une formation souterraine en contrôlant l'interaction entre la formation et les fluides introduits dans un forage pénétrant la formation ou produits à partir de ce forage. Ce procédé utilise la méthodologie de la diagraphie de stabilité/instabilité du forage en temps réel. Le procédé faisant l'objet de cette invention est illustré par un test de transmission de pression de pores (PPT). Dans un tel test, les fluides de test sont exposés à des schistes de Pierre II (20 % en poids d'une solution de NaCl et de fluide de silicate de sodium avec 20 % en poids de NaCl par exemple) dans un appareil PTT. L'efficacité membranaire des deux fluides, lors de l'exposition à du schiste affleurant est calculée et, sur la base de l'acquisition simultanée de données acoustiques, l'estimation d'une propriété dynamique de la roche est effectuée. L'étalonnage de la réaction de carottes (ou autres formations) de schiste représentatives aux fluides de forage (ou aux fluides d'entretien du puits, aux fluides d'extraction améliorée ou aux fluides de production) dans des conditions in situ réalistes facilite une modélisation précise de la stabilité/instabilité de la formation en fonction du temps sur le site d'exploitation pour toute la durée de vie du forage, depuis le début des opérations de forage jusqu'à la production, en passant par la complétion.

Title: Method and system for determining the use and non-use of software programs
Inventor: BARRITZ ROBERT
IPC: G06F11/34
Filed: 2001-08-22
Abstract: A method and system for auditing software systems by monitoring the use and non-use of software programs in a computer. An operating system of the computer controls execution of software products through the invocation of respective load modules thereof. A monitor is periodically triggered to collect load module execution information and a correlator correlates load module execution information with data that associates load module names wit h corresponding software products and develops a list of products executed in the computer over the course of a given time period. Alternatively, rather than operating periodically, the monitor collects load module execution information at the end of and by being triggered by computer processes controlled by the operating system. As a further alternative, the monitoring  of the execution of software products is detected by monitoring inputs and/or outputs to specific files or datasets, reflecting uniquely the use of corresponding software products. The invention also provides the ability to determine the load libraries and search order for load modules being execute d or called by the operating system.

Title: Quick change powder coating spray system
Inventor: SELIC ERICH W
IPC: B05B16/60
Filed: 2001-11-09
Abstract: Powder overspray that is extracted from a spray booth is recovered back to a powder supply that is used to supply powder to the spray guns (20) inside the spray booth. The powder overspray extracted from the booth is separated from the high flow air stream by a separator such as a cyclone separator (42). The powder falls into a transfer pan (314) and a vacuum is used to convey the powder from the transfer pan to a vacuum receiver (320). The powder is then discharged to the feed hopper (310) in the feed center (46). The use of a vacuum to convey powder from the cyclone to the feed center in effect permits substantially all of the powder overspray to be recovered from the spray booth directly to the feed hopper with minimal dwell or residence time within the cyclone or vacuum receiver subsystems during a spraying operation. The receiver can be rotated for easy cleaning, and the vacuum line (318) cleaned by one or more cleaning elements drawn through the vacuum line.
