Title: Method and system for set-top box service and support
Inventor: DAYMOND MICHAEL
IPC: H04N5/00
Filed: 2002-07-12
Abstract: The present invention relates a method and system for television set-top box (STB) service and support. Typical STBs provide little feedback to the user when there is an error or a failure, and generally only do so when the user attempts to perform a task. The system of the invention employs periodic testing of various devices and applications, so that the user is generally of failures in advance. As well, the testing is performed at different levels in the system, so that the user can be provided with troubleshooting information tailored to the particulars of the failure. Thus, when there is a failure, the user is provided with focussed instructions on how to address it. If the user ultimately has to contact a help desk, this feedback information can be passed to the help desk, which greatly reduces the burden on the help desk.

Title: Transfer microdissection
Inventor: EMMERT-BUCK MICHAEL R
IPC: G01N33/50
Filed: 2001-03-14
Abstract: The present disclosure concerns methods, systems, and devices for analyzing a biological material, such as a cellular or other specimen. In one disclosed example, the method selectively transfers biomolecules from a target region of interest in a biological sample (such as a tissue section). The transfer may occur, for example, by selectively focally altering a characteristic of a transfer layer adjacent the target region, such that the biomolecules can move through the altered area of the transfer layer. In particular examples, the transfer layer is altered by focally increasing a permeability of the transfer layer, for example by removing a focal portion of the transfer layer, and transporting the biomolecules through the altered region of the transfer layer, to microdissect the biomolecules of interest from the biological sample. In yet other embodiments, the microdissected biomolecules can be applied to an analysis substrate containing an identification molecule, such as a nucleic acid array, layered expression scan, or wells containing antibodies. Transfer microdissection allows biomolecules from regions of interest in the biological specimen to be selectively analyzed. For example, nests of highly atypical or metastatic cells in a tumor section can be analyzed for differential expression of certain proteins.

Patent CA-2426549-A1 (CA)
Inventor: KYRSTEIN JOHN P
IPC: B65G47/252
Filed: 2003-04-23
Abstract: This application relates to a self-contained apparatus for mechanically turning individual workpieces travelling on a conveyor, such as lengths of lumber travelling into or exiting from a sawmill. The invention reduces the need for lumber graders to turn lumber manually and thereby helps avoid repetitive motion injuries. The apparatus includes an adjustable height frame which is positionable alongside the conveyor. The frame supports a workpiece holder defining an open-ended slot for temporarily receiving an end portion of a workpiece. When the end of a lumber board or other workpiece is received within the holder, a proximity sensor causes the holder to rotate, thereby turning the workpiece lengthwise 180 degrees. The workpiece is then deposited on to the conveyor in its inverted orientation for further travel thereon. The apparatus may also optionally permit workpieces to pass through the holder when a "skip" rather than an "invert" signal is received. The workpiece holder may be connected to a rotatable shaft driven by an electric or hydraulic motor.

Title: Adaptive channel estimation using continuous pilot signal based on doppler period
Inventor: KUO WEN-YI
IPC: H04B1/707
Filed: 2002-01-31
Abstract: A method and apparatus to estimate the channel fade (both the amplitude gain/loss and the phase rotation) to assist the receiver (104) to detect and recover the transmitted signal (112) employs a continuous pilot signal such as the pilot code channel or pilot symbols. The channel estimator uses the same scrambling pattern of pilot channel and coherently integrates the continuous pilot signal to yield a channel estimate. The present invention employs adaptive integration duration to yield a channel estimate. The integration duration of the pilot signal for channel estimation is adaptive and proportional to the Doppler period. The Doppler period is proportional to the inverse of Doppler frequency and is an indicator of how fast the channel changes.
