Title: Apparatus for treatment of meniere's disease and similar conditions
Inventor: ENGVALL DANIEL
IPC: A61M13/00
Filed: 1999-06-29
Abstract: An apparatus for treatment of Ménère's disease by intermittently increasing, in an air (gas) pressure chamber being in communication with an outwardly sealed external ear volume bordering to the tympanic membrane, air (gas) pressure comprises a peripherally fixed flexible circular diaphragm forming a wall of the chamber and being displaceable in a perpendicular direction essentially without being tensioned. Displacement of the diaphragm away from the chamber is effected by air pressure built up in the chamber, not by separate displacement means. The apparatus further comprises linear electromagnetic means for displacing the diaphragm. The apparatus may include gas pressure sensing means; chamber pressure equalising means; microprocessor control means for controlling the displacement of the diaphragm and the pressure equalising means by signal input from the pressure sensing means.
Patent CA-2337491-A1 (CA)

Filed: 1998-10-06
Abstract: The genomic structure including the sequence of the intron/exon junctions is  disclosed for KVLQT1 and KCNE1 which are genes associated with long QT syndrome. Additional sequence data for the two genes are also disclosed. Als o disclosed are newly found mutations in KVLQT1 which result in long QT syndrome. The intron/exon junction sequence data allow for the design of primer pairs to amplify and sequence across all of the exons of the two gene s. This can be used to screen persons for the presence of mutations which cause  long QT syndrome. Assays can be performed to screen persons for the presence  of mutations in either the DNA or proteins. The DNA and proteins may also be  used in assays to screen for drugs which will be useful in treating or preventing the occurrence of long QT syndrome.

Patent CA-2350036-A1 (CA)
Inventor: PALOCZ-ANDRESEN MICHAEL
IPC: G01M99/00
Filed: 1998-11-04
Abstract: The invention relates primarily to the monitoring of emissions by motor vehicles, but also to those generated by ships, aircraft and diesel locomotives. The monitoring system can be built into new motor vehicles by the manufacturer or, in the case of older vehicles, be fitted by the driver.  Monitoring low-emission motor vehicles is difficult since different influences cause the measuring signal to fluctuate widely. The largest share of emissions occurs during the cold-start phase. Motor vehicles are fitted with an automatic starting system which by observing different parameters ensures an optimal start. While the vehicle is driving artificial errors are generated in the combustion system and the raised contaminant concentration is detected by the on-board monitoring system. An adsorption system reduces contaminant emission during the cold-start phase, in the case of engine- or exhaust gas treatment-related errors as well as in the event of severe air pollution. To regenerate the adsorption masses the contaminants are desorbed, fed back to the combustion chamber and burned.

Patent CA-2361176-A1 (CA)
Inventor: DESBIENS MARC A
IPC: G06Q10/04
Filed: 2001-11-02
Abstract: The invention allows several users to manipulate complex data interactively, but separately, and then have the results of their inputs merged. It is based on hierarchical planning which matches typical business environments. The planning process is distributed over the management hierarchy and each level may contribute one or more alternative plans for consideration by a superior level. The distribution of the process is carried out using computer-enabled ~delegation'. Relationships are specified between a dimensional structure and a responsibility structure such that sub-plans and plans using the dimensional structure of a planning data repository (PDR) may be partitioned into components corresponding to the responsibility structure. Part of'delegation' is the process of setting up the conditions, requirements, etc. for a subordinate to draft one or more sub-plans for their particular area. The subordinate then submits one or more of these sub-plans based on these conditions and information in the PDR, as well as on their specific experience and other (local) input. On 'submission', this sub-plan is able to be incorporated into higher level sub-plans. During the submission process sub-plans are integrated into a single plan, ensuring overall consistency of the data, and conformance with any constraints defined by users. The process is iterative in nature.
