Title: Multi-allelic molecular detection of sars-associated coronavirus
Inventor: KOSTRIKIS LEONDIOS G
IPC: C12Q1/70
Filed: 2004-08-13
Abstract: The subject invention relates to a multiple-allelic RT-real-time polymerase chain reaction (PCR) assay for coronaviruses including the SARS virus.  Multiple target sequences within the SARS-CoV, S, E, M and N genes are identified. The use of the four different targets enhances the likelihood that the fundamental genetic drift of the virus will not lead to a false negative result. Multiplex assays format for the assay are envisioned. Thus, the present invention allows for early diagnosis of a SARS infection. The assay would be useful in the context of monitoring treatment regimens, screening potential anti SARS agents, and similar applications requiring qualitative and quantitative determinations.

Patent CA-2538303-A1 (CA)
Inventor: WARREN DOYLE RAYMOND II
IPC: E21B47/20
Filed: 2002-02-13
Abstract: A downlink telemetry system providing improved apparatus and methods for communicating instructions via pressure pulses from surface equipment to a downhole assembly. The apparatus comprises a surface transmitter for generating pressure pulses, a control system, and a downhole receiver for receiving and decoding pulses. In operation, a bypass valve is opened and closed to create a series of pressure pulses received and decoded by a downhole receiver. The method significantly reduces the time required for downlink communication without interrupting drilling and without interrupting uplink communications such that simultaneous, bi-directional communication is achievable if the uplink and downlink signals are sent at different frequencies. The telemetry scheme and algorithm provide an inventive method for filtering and decoding the downlink signals. The algorithm determines the time intervals between pulse peaks and decodes the intervals into an instruction. The algorithm also includes error checking for verifying that the instruction was properly received downhole.

Title: Method and apparatus for cost effective central transcoding of video streams in a video on demand system
Inventor: BROWN CHRISTOPHER W
IPC: H04N7/173
Filed: 2004-11-19
Abstract: A communications system (10) for processing video signals in a video-on-demand service employs centralized transcoding in a way that a relatively small amount of transcoding equipment (15) is required, as opposed to transcoding every transport stream. In addition, the embodiments of the present invention do not require transitions from non-transcoded sessions to transcoded sessions. According to one aspect of the present invention, bandwidth is reserved at the node groups (14a-c) for transcoded services, and transcoding is initiated before the node group (14a-c) exceeds its assigned bandwidth.  This method provides the opportunity to add additional transcoded services and start decreasing bandwidth allocations to individual channels or services without interrupting existing sessions.
