Patent CA-2584671-A1 (CA)
Title: System and method for downhole telemetry
Inventor: WHITE MATTHEW ROBERT
IPC: E21B47/12
Filed: 2007-04-13
Abstract: A system and method are provided for providing electromagnetic (EM) measurement-while--drilling (MWD) telemetry capabilities using an existing mud- pulse MWD tool. An EM tool intercepts the output from the mud-pulse tool and generates an EM signal that mimics a mud--pulse pressure signal. The EM signal is intercepted at the surface by a receiver module that conditions the signal and inputs the signal into the existing pulse tool receiver. Since the EM signal mimics a mud-pulse signal, the pulse tool receiver does not require software or hardware modifications in order to process an EM telemetry mode. The EM tool can be adapted to also provide dual telemetry by incorporating a conventional pressure pulser that would normally be used with the pulse tool.

Patent CA-2601757-A1 (CA)
Inventor: DO PHAN L
IPC: H04N7/26
Filed: 2006-03-22
Abstract: A dynamically scaled file encoding method and apparatus are disclosed. A file encoding system using JPEG encoding can be configured to produce relatively constant compressed file sizes irrespective of the initial file size and file contents. The system retrieves an initial file or image that is to be compressed and determines a target bit rate corresponding to the compressed file. The target bit rate is used to determine an initial scaling factor. The initial file is encoded using a JPEG encoder having coefficients scaled by the initial scaling factor. The resultant bit rate can be adjusted in a second loop if greater than the desired bit rate. To adjust the bit rate, a recomputed scaling factor is determined from the resultant bit rate. The initial file is then encoded with coefficients scaled by the recomputed scaling factor to achieve a bit rate that is within the target bit rate.

Title: A field adjustable control valve assembly and field adjustment module
Inventor: PAPANIDE ADRIAN I
IPC: F16K37/00
Filed: 2006-05-05
Abstract: A flow setting assembly is provided to permit field adjustment of an electronically actuated flow control valve, particularly a pressure independent characterized control valve (PICCV). In a preferred form, flow can be field adjusted by using a hex tool. Therefore, the maximum flow can be increased or decreased within the valve's adjustable flow range. As with all high close-off valves that employ a ball in their design, the ball passes well into the seat when rotated to the actuator's zero-degree position. Therefore, there is an amount of travel within the first degrees of ball rotation that passes back over this seat. The flow setting assembly eliminates this excess rotation (12~) resulting in a closed position that is offset to improve control resolution and system accuracy. This offset continues to allow the high close-off rating of 200 PSI. MFT actuators electronically adjust to and maintain the 2- 10 Volt control signal at the reduced angle, as well as the 100 second running time and feedback signal. On floating point (-3) actuators, the running time is constant but dependent on the overall angle of rotation.
