Patent CA-2387415-C (CA)
Inventor: LASKOWSKI EDWARD L
IPC: G07D7/06
Filed: 1997-11-14
Granted: 2003-04-01
Abstract: An apparatus and method for providing an indication of a type of note passing through the apparatus includes a note transport (12) which moves the note past transversely spaced spot sensing assemblies (18). Each spot sensing assembly includes four emitters (32). Each of the emitters produces radiation at a different wavelength. The spot sensing assemblies include a reflectance detector (20) and a transmission detector (22) which are disposed on opposed sides of the passing note. The emitters direct radiation onto test spots (34) on the passing note. The emitters in each assembly are activated individually and repeatedly in a sequence. Radiation reflected from each type of emitter to the reflectance detector at each test spot causes a control circuit (24) to generate reflectance values. Radiation transmitted from each emitter through each test spot to the transmission detector causes the control circuit to generate transmission values. The control circuit produces a sensed value set including the reflectance and transmission values from each of the emitters in each of the spot sensing assemblies. The control circuit also determines an angle of skew of the passing note. The control circuit is in connection with a data store which includes memories (138). Each of the memories includes data representative of templates of values corresponding to transmission and reflectance values for known note types in a number of note positions. The control circuit generates stored value sets from the templates and skew angle. The control circuit further calculates a value representative of a level of correlation between the sensed value set and each of the stored value sets. The control circuit determines the highest level of correlation between all the stored value sets which is indicative of the note type.

Abstract: A system and method for voice transmission over high level network protocols. On the Internet and the World Wide Web, such high level protocols are HTTP/TCP. The restrictions imposed by firewalls and proxy servers are avoided by using HTTP  level connections to transmit voice data.  In addition, packet delivery guarantees are obtained by using TCP instead of UDP. Variable compression based on silence detection takes advantage of the natural silences and pauses inhuman speech, thus reducing the delays in transmission caused by using HTTP/TCE  The silence detection includes the ability to bookend the voice data sent with small portions of silence to insure that the voice sounds natural. Finally, the voice data is transmitted to each client computer independently from a common circular list of voice data, thus insuring that all clients will stay current with the most recent voice data. The combination of these features enables simple, seamless, and interactive Internet conferencing.

Abstract: Pour l'extraction minière de matières premières, il est nécessaire de provoquer des explosions lors desquelles des charges explosives placées dans de nombreux trous de mine sont amorcées les unes après les autres selon un schéma temporel déterminé. Les détonateurs électroniques (4a-4c) des charges explosives, qui forment un système d'amorce, sont reliés ensemble à un dispositif de programmation et de déclenchement  par l'intermédiaire d'une ligne (3) de bus. Lors de la communication d'un détonateur avec le dispositif (2) de programmation et de déclenchement des détonateurs, des problèmes surgissent toutefois du fait que les autres détonateurs connectés à la ligne de bus représentent des résistances capacitives qui ont une influence sur la transmission des données. Selon la présente invention, une tension continue supérieure à la tension prévue pour la production de signaux est appliquée au circuit de tir (1) pendant une durée prédéterminée, avant une communication prévue entre un détonateur et le dispositif. Les signaux avec lesquels sont produites les données que le détonateur transmet en tant que réponse sont produits avec une tension inférieure à la tension supérieure précédemment appliquée, et, avant la réponse d'un autre détonateur, la tension continue est à nouveau augmentée.

Abstract: A method and apparatus (20) for decontaminating a fluid (F), particularly water and wastewater, uses pulsed ultra-violet (UV) light (52) in an automatic pump driven configuration that separately and in real time adjusts each UV reactor module for both water flow and UV power (average and peak intensity) to accommodate a wide range of influent conditions, thereby producing the quality of water discharge desired by the operator Process control is configured on the basis of a UV transmission-based feedback control loop and on a truly active and independent adjustment of ea ch reactor module, as opposed to the relative passive and dependent adjustment techniques of the prior art. By matching the condition of the source water to the amount of UV dosage required to produce from it the desired water discharge quality, and then achieving this dosage in real time by the most practical optimum combination of average/peak power and variable pump rate, the method and apparatus represent a new way of achieving automated, high efficiency wastewater decontamination.

Abstract: An oxygen fueled combustion system includes a furnace having at least one burner, an oxygen supply for supplying oxygen having a predetermined purity, and a carbon based fuel supply for supplying a carbon based fuel. The oxygen and the carbon based fuel are fed into the furnace in a stoichiometric proportion to one another to limit an excess of either the oxygen or the carbon based fuel to less than 5 percent over the stoichiometric proportion. The combustion of the carbon based fuel provides a flame temperature in excess of 4500°F. The exhaust gas stream from the furnace has substantially zero nitrogen-containing combustion produced gaseous compounds from the oxidizing agent and reduced green-house gases.  Substantially less carbon based fuel is required than conventional combustion systems without a loss of energy output.
