Title: Mobile rock crusher
Inventor: OLYNYK JERRY
IPC: E01C19/05
Filed: 2001-10-12
Abstract: A mobile rock crusher for crushing raw rock material which has been windrowed on a roadway in the translation path of the crusher includes a rigid supporting structure, which includes a frame, and translation means for allowing translation of the frame over the roadway. A selectively actuable scoop is pivotally mounted to the frame for selectively actuable lowering over the roadway into sliding engagement with, so as to collect, the windrowed raw rock material onto the scoop. A first conveyor is mounted to the frame. An upstream loading end of the first conveyor cooperates with the scoop for conveying the raw rock material from the scoop onto a first screen at a downstream depositing end of the first conveyor. The first screen is for screening larger diameter material from smaller diameter material in the raw rock material so that the smaller diameter material falls through the first screen.  The larger diameter material translates over the first screen so as to fall into a first crusher mounted to the frame beneath the first screen. A second conveyor mounted to the frame beneath the first crusher is for conveying crushed material from the first crusher into a second crusher mounted to the frame for crushing the crushed material for deposition from the second crusher onto the roadway.

Title: System and method for automating transcription services
Inventor: QIN CHARLES
IPC: G10L/
Filed: 2000-02-04
Abstract: A system for substantially automating transcription services for multiple users (10, 11, 12) including a manual transcription station (50), speech recognition program (40) and a routing program (200). A uniquely identified voice dictation file is generated from a user and -- based on the training status -- routes the voice dictation file to a manual transcription station and speech recognition program. A human transcriptionist creates transcribed files for each voice dictation file. The speech recognition program creates written text for each dictation file if the training status is training or automated. If the training status of the current user is enrollment or training, a verbatim file is manually established and the speech recognition program is trained with an acoustic model using the verbatim and voice dictation files. The transcribed file is returned to the user if the training status is enrollment or training or writtent text is returned if the status is automated.

Title: Interference cancellation in radio stations
Inventor: KARLSSON JONAS
IPC: H04B1/707
Filed: 2000-02-25
Abstract: The invention is concerned with a radio receiver station, a multi-user interference cancellation unit and a multi-user cancellation method in a system with several transmitting radio stations. In the method, a radio signal is received as a sum of the signals from at least two of the transmitting radio stations in the system. Interference from at least two of the transmitting radio stations is cancelled. The interfering signals from at least some of the transmitting radio stations are processed in at least two separate operations in one or more stages, the result of each separate operation being taken into consideration in the estimation of the desired modulated signal sent to the receiver. Preferably, a part of the interfering signals is processed in one of the separate operations, while the rest of the interfering signals are processed in the other separate operations. If the cancellation is carried out in more than one step, the cancellation results of the first cancellation stage are used in the second interference cancellation stage, the method being correspondingly continued in the possible further cancellation stages.
