Abstract: A method and system for providing non-sequential access to visual information that is being digitally encoded in a digital data stream is provided. The digital data stream includes a sequence of video frame data.  Each video frame data in the sequence of video frame data corresponds to a video frame of the visual information. The digital data stream is generated with an encoder. The encoder generates tag data that indicates locations of the video frame data within the digital data stream. The digital data stream is stored at a location from which the digital data stream is delivered to a client. Tag data is stored at a location from which the tag data may be used to provide the client non-sequential access to the digital data stream. A selected set of video frames within the digital data stream is selected based on the tag data in response to a request for non-sequential access by the client. A  second digital data stream that includes the video frame data that corresponds to each video frame of the selected set of video frames is constructed and transmitted to the client.

Abstract: A pilot control valve for controlling a reciprocating pump having a valve member shiftable within a valve body between a first or "downstroke" position and a second or "upstroke" position. When the valve member is in its first position, the valve member allows communication of control fluid to the lower surface of a piston to move the piston from a first position to a second position. As the piston reaches its second position, a vent in a rod attached to the piston allows control fluid acting on the valve member to depressurize.  As such control fluid is depressurized, pressurized control fluid acts on the valve member to move the valve member from its first position to its second position. In its second position, the valve member blocks communication of the control fluid to the lower surface of the piston and allows communication of the control fluid to the upper surface of the piston causing the piston to return to its first position. As the piston returns to its first position, the vent in the piston rod allows the pressurized control fluid acting on the upper surface of the piston to act on the valve member to move the valve member back to its first position. In its first position, the valve member blocks communication of the control fluid to the upper surface of the piston and allows communication of the control fluid to the lower surface of the piston and the process is repeated In this manner, the pilot control valve of the present invention achieves a consistent pumping rate for a reciprocating device coupled to the pilot control valve.

Abstract: A sucker rod tool system for oil wells monitors both torque and angular displacement of a three-element sucker rod connection. The tool system engages two sucker rods that are at least partially screwed into opposite ends of a sucker rod coupling. The system, however, does not engage the coupling adjoining both rods. The system determines whether a connection has been properly tightened by sensing the torque and angular displacement of the connection as it is being tightened, and comparing the data to a stored reference set of data or curves. In some embodiments, a properly tightened connection is based upon the number of straight lines that are needed to adequately approximate a plotted curve of the sensed torque versus angular displacement. Tightness of each connection of a string of sucker rods is recorded with reference to each connection's depth within a well to later serve as an aide in diagnosing connection failures. In some cases, the energy required to unscrew a connection is also recorded. In some embodiments, the system automatically determines whether one or both sucker rods of a three-element connection need to be tightened.

Title: Synchronization signal detector and method
Inventor: SIMMONS SEAN B
IPC: H04J3/06
Filed: 2001-11-27
Granted: 2004-07-06
Abstract: A synchronization (sync) signal detector and associated method detect the occurrence of a known sync signal in a received signal. The known sync signal is generated and correlated with the received signal to generate a correlation waveform.   A peak value of the correlation waveform, indicative of the occurrence of the sync signal in the received signal, is detected and used to determine a timing offset between the received signal and the sync signal. The sync signal is then shifted in time to compensate for the timing offset. Such shifting of the sync signal is simpler and requires substantially less processing time and resources compared to known sync signal detection schemes, in which a received signal or the sampling timing of a received signal is shifted to compensate for timing offset.

Title: Coriolis flowmeter with reduced dimensions
Inventor: CRISFIELD MATTHEW T
IPC: G01F1/84
Filed: 2000-03-15
Granted: 2004-06-01
Abstract: A Coriolis flowmeter sensor (10) having a reduced flag dimension. Flag dimension is the length that a flow tube loop extends outward from a pipeline. In order to have a reduced flag dimension, the entire length of the flow tubes (103A-103B) must vibrate to make the flowmeter sensor (10) more sensitive to Coriolis effects. When the entire length of the flow tubes vibrates, a first set of brace bars (122-123) connected to the flow tube separates the frequencies of vibration in the flow tubes (103A-103B). A second set of brace bars (120-121) connected to the flow tubes enhances the zero stability of the flowmeter.

Abstract: The disclosed data compressor compresses an input stream of data characters using LZW data compression. When the occurence of a run of input data characters is detected, the run is processed by successively looking ahead into the input to determine the contiguous numerically increasing segments that exist in the run and by utilizing codes from the compressor code counter to correspond to the contiguous numerically increasing run segments.  Alternatively, the detected run is processed by determining the length of the run and mathematically determining, from the length of the run, the respective codes from the code counter corresponding to the contiguous numerically increasing segments that exist in the run. Specifically, an iterative mathematical algorithm or a quadratic equation algorithm are utilized to process the run.
