Abstract: A technique is provided for incrementally maintaining column cardinality estimates in database management systems. The system catalog table containing a cardinali ty estimate for a column is extended to include an appropriate data structure. A modified line ar counting technique is used in a first embodiment of a method for column cardinality estimation. Moreover, a modified logarithmic counting technique is used in a second, preferred embodiment of a column cardinality estimation method to reduce storage requirements for the data structure. The cardinality estimate is produced by an initial scan of the data but is then further maintained without requiring a full scan of the data. Data changes are reflected incrementally in modifications to the initial cardinality estimate, keeping the cardinality statistics more current with respect to the database condition. The technique of the invention typically provides a capability for a database management system to produce more efficient search plans providing more effective responses to user queries through the use of improved cardinality statistics.

Title: System and method for registering motion picture film
Inventor: GOODHILL DEAN K
IPC: G03B1/42
Filed: 2001-01-12
Abstract: A system and method for registering the frames of film with respect to an aperture (32) in a motion picture projector.  A registration reference mark is applied to each frame corresponding to the location of the frame on the film. When the film is intermittently stopped in the projector's film gate (22), the registration reference mark is read to determine the location of that frame relative to the immediately preceding frame. If the frame in the gate (22) is misregistered, the gate is moved to correctly register the frame prior to projection. By properly registering the frames, the "jitter" and "weave" associated with conventional projectors is eliminated and resolution of the projected film image is enhanced.

IPC: E21B49/08
Filed: 2000-08-25
Abstract: An apparatus and method for maintaining the pressure of a well fluid sample as the sample is transported to the well surface from a downhole wellbore location.  The invention collects a formation fluid sample under pressure. The fluid sample is further pressurized with a traveling piston powered by the hydrostatic wellbore pressure. The pressurized formation fluid sample is contained under high pressure within a fixed volume chamber for retrieval to the well surface. Multiple collection tanks can be lowered into the wellbore during the same run to sample different zones with minimal rig time. The tanks can be emptied at the well surface with an evacuation pressure so that the fluid sample pressure is maintained above a selected pressure at all times.
