Abstract: A system that provides remote ordering for a Coriolis flowmeter. The system is provided by a server. The server begins by receiving input flow stream parameters from a remote client computer. The server then determines flowmeter parameters from the input flow stream parameters received from the remote client computer. The server then determines at least one model of flowmeter suitable for the flowmeter parameters. The suitable models of flowmeters are then transmitted to a remote computer where a customer may then place an order for one of the models suitable for the flowmeter parameters.

Abstract: Methods and associated structure for saving and restoration of state information regarding progress of an automated test procedure to permit resumption of the automated test procedure following reset or failure of the automated test system. An automated test system in accordance with the present invention preferably saves state information in a non-volatile storage medium, such as a disk file, indicative of the progress of the test procedure. When the test system environment in which the automated test system is operable is reset or restarted, intentionally or due to failure, the automated test system retrieves previously saved state information from the non-volatile storage medium to resume the automated test process in accordance with the saved state information.

Abstract: Devices (e.g. “servers”) in a data storage system access data contained in logical volumes contained in a plurality of storage devices or storage arrays. The servers issue access requests through any available transfer path from the servers to the storage devices or storage arrays. I/O (input/output) devices control access between the servers and devices that control access to the data (e.g. “array controllers”), so that the access requests from the servers are uniformly routed to the preferred array controllers independently of the transfer paths through which the servers issue the access requests.

Abstract: Control circuitry for a disk drive system that has improved data detection by using log likelihood values and erasure pointers. The control circuitry is comprised of a log likelihood modification system and a decoder. The log likelihood modification system receives log likelihood values that represent data and erasure pointers. The erasure pointers point to at least one of the log likelihood values that has been corrupted in some manner. The log likelihood modification system sets the log likelihood values, that the erasure pointer points to, to an error value to generate modified log likelihood values. The log likelihood modification system transfers the modified log likelihood values to the decoder. The decoder processes the modified log likelihood values based on code constraints to generate estimated log likelihood values. The decoder then decodes the data from the estimated log likelihood values.

Abstract: An array controller of a data storage system initiates a test of another array controller of the data storage system to determine the operational condition of the controller under test (CUT) as well as an array of storage devices to which the CUT is connected and a network fabric over which the CUT receives commands from host devices of the data storage system. If the CUT or devices connected thereto are not functioning properly, the controller initiating the test can diagnose the problem. The controller initiating the test instructs the CUT to perform certain normal operating functions, e.g. data read and write functions, and checks whether the functions are completed correctly. Additionally, a loopback test checks the operation of the network fabric, and the read and write functions also check the operation of the storage devices.

Abstract: A system, method, and software are disclosed that determine a proportion of a majority component of a fluid that is flowing through a Coriolis flowmeter. Circuitry receives pickoff signals and a temperature signal from the Coriolis flowmeter responsive to the fluid being flowed through the Coriolis flowmeter. The circuitry processes the pickoff signals and the temperature signal to determine a proportion of the majority component relative to the fluid. To determine the proportion of the majority component in one example, the circuitry determines a first volumetric flow rate based on a measured mass flow rate of the fluid and a reference density of the majority component. The circuitry then determines a second volumetric flow rate based on a measured volumetric flow rate, a temperature-varying density, and the reference density. The circuitry determines the proportion of the majority component based on the first volumetric flow rate and the second volumetric flow rate.

Abstract: Servo circuitry for counting tracks on an optical storage medium is disclosed. The servo circuitry is comprised of a differential phase detector and a digital phase-locked loop. The differential phase detector receives four signals from a quad-photodetector and correlates the four signals into a first correlation signal and a second correlation signal. The digital phase-locked loop receives an adjustable amplification value along with the positive correlation signal and the negative correlation signal. The digital phase-locked loop generates a track count signal based on the adjustable amplification value, the positive correlation signal, and the negative correlation signal. The track count signal represents track crossings on the optical storage medium. The digital phase-locked loop advantageously has an adjustable bandwidth based on the amplification value. The servo circuitry count tracks on both CDs and DVDs.

Abstract: The present system for determining the phase and amplitude of a radio occultation signal modifies the traditional Open Loop tracking process to maximize the signal-to-noise ratio, minimize the sampling rate, and also preserve the structure of the radio occultation signals. A radio occultation system includes a transmitter system, a receiver system, and a post-processing system. The receiver system receives the radio signal that is transmitted by the transmitter system through the earth's atmosphere, where it is occulted, and down converts the received radio occultation signal to generate a down converted signal based on a phase model that uses a refractivity climatology. The receiver system then low pass filters the down converted signal and samples the in-phase and quadrature components of the down converted and low pass filtered signal.

The velocity determination system determines the radial velocity based on a ratio of the correlation of the first signal and the second signal. The velocity determination system then determines a transverse velocity based on a ratio of the correlation of the first signal and the second signal in a forward mode and a backward mode along a transverse direction.

Abstract: A method of forming a flowmeter having a case enclosing a single straight tube surrounded by a balance bar. The balance bar ends are coupled by means of a brace bar to the flow tube as well as by case connect links to the inner wall of the case.

Abstract: A process is disclosed for determining properties of a flow tube and of a fluid flowing through the flow tube. One example of such a property is the density of the fluid flowing through the flow tube. To determine the properties, the process determines a measured mode shape based on pickoff signals received from a plurality of pickoffs. The process selects values for flow tube and fluid parameters. The process determines an estimated mode shape based on the values for the flow tube and fluid parameters. The process compares the measured mode shape and the estimated mode shape to determine an error for the values for the flow tube and fluid parameters. If the error for the values is within an error range, then the process determines the properties of the flow tube and of the fluid based on the estimated values. If the error for the values is not within the error range, then the process selects new values for the flow tube and fluid parameters.

Abstract: A calibration factor for a sensor including a material-containing conduit and a plurality of motion transducers operative to generate motion signals representing motion of the conduit is determined from a normal modal dynamic characterization of motion of the conduit. The calibration factor may be generated by generating a solution to a modal differential equation of motion in a modal domain including a plurality of normal modes of motion of the conduit, and by generating the calibration factor from this solution.

The modal Coriolis term may be determined from a mode shape function that describes modal motion of the conduit as a function of location on the conduit. The invention may be embodied as methods, apparatus and computer program products.
