Patent CA-2357291-A1 (CA)
Inventor: KONJEVIC ZORAN
IPC: H04N7/15
Filed: 2001-09-13
Abstract: A system and method for interactive instruction in the learning of a musical instrument, which also allows musicians at geographically remote locations to collaborate in the creation and performance of musical works. The invention provides a server-based musical "classroom" to which student musicians can connect via a global computer network, such as the Internet, in order to obtain personalized, interactive musical instruction on the instrument of their choosing and by the instructor of their choosing. The server supports host software which simulates a selected environment and even a selected tutor, for example a famous musician, to interact with the student. Client software interposes a graphical representation of the student into the virtual "classroom" with the virtual tutor, generating as closely as possible the reality of an actual classroom experience and allowing the student watch the virtual tutor playing the musical instrument from different perspectives.  In the collaborative embodiment, the method and system of the invention generates a graphical representation of each musician on a simulated or virtual stage, in real-time, and mixes the musical performance of each musician into a collaborative group performance in the virtual setting of their choosing, which optionally can be streamed live to an audience who has access to the virtual stage. The musical performances of the individual instrumentalists can also be combined with pre-recorded or synthesized performances by virtual instrumentalists, allowing the musicians to perform with virtual representations of their favourite artists.

Patent CA-2362916-A1 (CA)
Inventor: SILVERSTEIN FRED E
IPC: A61B19/00
Filed: 2000-02-29
Abstract: An anatomical marker uses a permanent magnet to indicate a selected location  within a patient. The magnet is enclosed within a non-degradable envelop and  is coupled to a retention member that is preferably manufactured from a biodegradable material, such as a polyglucuronic acid based material. The retention member may include one or more barbs to retain the anatomical mark er in the selected location. An insertion tool, usable with an endoscope, can insert the anatomical marker. A retention magnet is fixedly attached to the insertion tool and holds the anatomical marker in place due to the attractiv e magnetic forces between the retention magnet and the marker magnet in the no n- biodegradable envelope. When the anatomical marker is securely fastened at t he selected location in the patient, the forces exerted by the patient's body o n the retention member exceed the attractive magnetic forces between the retention magnet and the magnet in the envelope, thus causing the anatomical  marker to be released from the insertion tool. The location of the magnet ma y be subsequently detected using a magnetic detector system.

Abstract: A capacitive motion encoder (140), for sensing the position of a moving object relative to a stationary object, includes at least one stationary element (141), coupled to the stationary object and a moving element (148), coupled to the moving object and in proximity to the stationary element. A field transmitter (142) generates an electrostatic field, which is modulated by a change in capacitance between the stationary and moving elements responsive to relative motion of the elements. A conductive shield (154) is electrically decoupled from both the moving and the stationary objects, and encloses the moving and stationary elements so as to shield the elements from external electrical interference. Processing circuitry (138) is coupled to sense the modulated electrostatic field and to determine responsive thereto a measure of the position of the moving object.

Title: Management apparatus, editing apparatus, recording medium, method, and audio data playback management system including management apparatus, editing apparatus and recording medium
Inventor: INOUE SHINJI
IPC: G06F21/00
Filed: 2001-03-09
Abstract: A management apparatus (FIG. 1) stores pairs of copyrighted contents and numbers of permitted check-outs. On being requested to perform check-out for  a semiconductor memory card, the management apparatus records an audio object (AOB) corresponding to a content in the semiconductor memory card, assigns a  content ID to the AOB, and decrement a corresponding number of permitted che ck- outs. An editing and playback apparatus edits the AOB and assigns a content ID, which is the same as the content ID of the original AOB, to each new AOB  obtained by the editing. A local storage holds history information including  a media ID and the content ID assigned to the original AOB. On being requested  to perform check-in for the semiconductor memory card, the management apparatus sets, in a non-playable state, the AOB assigned a content ID that is the same as the content ID in the history information and increments the number of permitted check-outs.

Title: Method and apparatus for compressing scripting language content
Inventor: BOOTH ROBERT CHARLES
IPC: H04L29/06
Filed: 2000-08-25
Abstract: A method and apparatus for compressing scripting language content, such as HyperText Markup Language (HTML). Codewords are provided for HTML elements, such as tags and their attributes, to reduce the amount of data, e.g., in a Web page. The codewords are combined (230) with translated (or coded) text (215) to provide comprssed HTML data. The codewords may have reserved bits t o distinguish empty tags from container tags, and to indicate whether a container tag is a starting or closing tag, or the provide other info rmatio n about the tag to aid in processing. The amount of data that must be communicated, e.g., to represent a Web page that is transmitted to a subscriber terminal, is thereby reduced. Additionally, the invention allows the use of a graphics engine (156) or browser (159), e.g. in a subscriber terminal (150) that processes/renders the compressed HTML data (e.g., codewords) directly without decompressing them. The technique is compatible with other compression techniques to provide even greater compression.</SDOA B>

Filed: 2001-09-10
Abstract: A probe for insertion into molten metal to detect and measure particulates suspended therein includes an inner tube of an electrically insulated material forming a metal receiving chamber, the tube having an orifice to permit molten metal to flow into the chamber.  A first electrode extends into the chamber for engaging metal within the chamber and a second electrode surrounds at least a portion of the inner tube for engaging molten metal outside of the chamber. The electrodes may be connected to a measurement device for establishing a current path through the electrodes and passing through the orifice for measuring changes in the electrical potential produced by the passage of particulates entrained in the molten metal passing through the orifice. An outer sheath of heat resistant material surrounds a portion of the second electrode and a gas passageway extends out of the inner tube for connecting to a vacuum source to create a pressure differential within the chamber for facilitating the flow of molten metal through the orifice. A liquidus depressing material is in the chamber for alloying with molten metal entering the chamber to lower the liquidus temperature of the molten metal and permit a longer time period for detecting and measuring particulates in the molten metal.
