Patent CA-2613625-A1 (CA)
Title: Remote control for braking system of progressive cavity pump
Inventor: LARA EDUARDO PERDOMINI
IPC: F04C14/06
Filed: 2007-12-04
Abstract: A brake actuator has a motor that provides input rotation in first and second directions. A reducer couples to the motor and reduces the input rotation into an output rotation to be applied to a brake screw of a progressive cavity pump drive. A sensor measures rotational speed of the drive shaft. In manual operation, an operator can view an indication of the rotational speed and can manually operate the motor accordingly to control rotation of the shaft.  In automated operation, a controller automatically controls the motor based on the rotational speed measured by the sensor. The controller can also use a torque sensor to detect the torque applied to the brake screw, a displacement sensor to detect displacement of the brake screw, and/or a current sensor to detect the current consumption of the motor.

Filed: 2006-08-25
Abstract: The invention relates to a method for determining a sequence of values for a coding parameter of a hybrid coding scheme for every frame of a frame sequence for use in the coding of the frame sequence by means of the hybrid coding scheme. The hybrid coding scheme allows to determine resulting distortions and compression rates for the frames of the frame sequence if the frame sequence is completely coded and if a genuine partial sequence of the frame sequence is incompletely coded, in such a manner that a genuine subset of the set of distortions and compression rates such as they can be obtained by coding using possible sequences of predetermined values for the coding parameter for every frame. Estimated distortions and compression rates for frames of the frame sequence are determined (202) and the sequence of values for the coding parameter of the hybrid coding scheme is determined based on the resulting and estimated distortions and compression rates previously determined.
