Title: Traitement biochimique de residus de la mousse de bitume
Inventor: HULS BERNARDUS J
IPC: C10G32/00
Filed: 1999-09-10
Abstract: L'invention concerne un traitement biochimique de résidus de la mousse de bitume dérivés du traitement des sables bitumeux et de l'extraction de la mousse de bitume. Lors du traitement, on mélange ces résidus de la mousse de bitume, contenant des micro-organismes métabolisant les hydrocarbures à l'état naturel, avec un support de croissance de manière à former un inoculum qui est ensuite incubé dans des conditions isothermiques pendant un laps de temps défini afin de produire une culture bactérienne mixte renfermant une biosolution et un produit à l'eau contenant une quantité réduite d'asphaltènes ainsi que des solides, notamment de l'argile et du sable. La biosolution obtenue dans ce procédé est utilisée par la suite dans le processus de conditionnement des sables bitumeux initiaux à partir duquel la mousse de bitume est obtenue, puis dans le processus d'extraction de sables bitumeux via l'injection directe de biosolution dans la formation des sables bitumeux. En raison de la présence d'un certain nombre de micro-organismes métabolisant les hydrocarbures dans la culture bactérienne mixte, la biosolution est également utilisée dans la dégradation des asphaltènes. Le traitement se traduit donc par la diminution de la quantité de déchets produits lors de l'extraction de bitume. De plus, puisque l'on utilise un tensio-actif biologique contenant une biosolution dans le conditionnement des sables bitumeux initiaux, la mousse de bitume peut être obtenue à des températures inférieures et sans avoir recours au soda caustique, ce qui est actuellement pratique courante. Aussi, l'invention permet-elle d'éviter, ce qui représente un avantage, la production de boues de résidus dérivés de la dispersion d'argile.

Inventor: DURING JAN
IPC: H04B10/07
Filed: 2001-09-07
Abstract: A method and system for measuring performance characteristics such as bit error rate (BER) in a multiple parallel-channel digital communications system. A transmitter such as a VCSEL array outputs multiple, high data rate, digital signals onto an appropriate media for reception at a receiving end. The test architecture uses a test pattern generator at the transmitter end and a data re-shaper connected to a receiver in each channel. The output of each re-shaper is serially connected back into the next channel transmitter until each channel has been tested. An error detector connected serially to the last receiver provides an evaluation of the characteristics of the multiple channels.

Patent CA-2364349-A1 (CA)
Inventor: POPOVIC BRANISLAV
IPC: H04J13/00
Filed: 2000-03-03
Abstract: The present invention employs one or more complementary sequences, e.g., Golay pairs of sequences, to provide accurate and efficient synchronization between radio transceivers. A matched filter corresponding to a complementary pair of sequences is used to correlate the received signal with one of the complementary pair of sequences. A peak output is detected from the matched filter, and the detected peak is used to generate a timing estimate for synchronizing transmissions between transceivers. Each of the complementary sequences has minimal aperiodic autocorrelation sidelobe values for all non-zero delays of that complementary sequence and a maximal autocorrelation main lobe value for a zero delay of that complementary sequence. The one sequence may be used as a preamble portion of a random access message transmitted by a mobile station to a base station over a random access channel. The sequence may also be used as a synchronization code transmitted by the base over a synchronization channel and used by mobile stations to obtain synchronization.  An efficient Golay correlator and a bank of efficient Golay correlators for correlating respectively with a single sequence and with a set of orthogonal sequences are disclosed.

Patent CA-2377617-A1 (CA)
Title: Provision of media content to telephony callers on-hold
Inventor: MCCORMACK TONY
IPC: H04M3/428
Filed: 2002-03-20
Abstract: A method of providing media content, such as music and video, to callers on hold involves the generation of the media content locally in the environment of the held caller, rather than the transmission of the content over the network. The local call server of the held caller is signalled when the call has been placed on hold by the server which has placed the call on hold. The caller's server then activates a music-on-hold server (or other media content generator) to provide the media content directly to the caller's telephony terminal. The advantage of this is that the media content is not transmitted across the network, allowing a higher bandwidth to be used locally for the media content without utilising wide area network resources. This results also in the media content being provided in a higher quality format to the caller, avoiding the loss of quality associated with transmitting music using compressive voice codecs over packet-based networks.
