Abstract: A magnetic insertion meter is disclosed herein. Disclosed insertion meters include in some examples, a sensor head tube having a textured front surface and at least two electrodes. Disclosed insertion meters include a textured front surface adapted to move the separation point of a fluid flowing over the sensor head tube towards the upstream surface as compared to the same sensor head tube without the textured front surface. Methods of measuring flow are also disclosed herein using example magnetic insertion meters.

Abstract: A scalable monolithic sensor assembly, controller, and methods of making and installing same are disclosed. The sensor assembly includes a sensor head sized to fully traverse the diameter of the pipe such that its electrodes sample a voltage indicative of the entire pipe flow across its diameter. An improved stem design is included that decreases insertion force and increases lateral stability of the sensor head. An improved insertion device is disclosed that provide for independent axial insertion and rotation. An improved core is disclosed that minimizes interference of magnetic fields and reduces manufacturing costs. An improved controller is disclosed that improves sensitivity.

Abstract: Methods of inserting a sensor assembly into a flow pipe are disclosed. The methods may include fastening a preload nut into a hot tap housing, applying force to at least one handle connected to a stem to insert the sensor assembly into the flow pipe, and fastening a collar onto the stem. In one example, the collar is between the preload nut and the hot tap housing. And, in one example, the methods may include tightening the preload nut into the hot tap housing until the preload nut bottoms out at a hard stop.

Abstract: Data acquisition rates are dynamically adjusted in an APM system, by monitoring data acquisition hardware and reducing the data acquisition rate when a determination is made that the data rate is too high for processing by an APM.

Abstract: A method and apparatus to estimate application and network performance metrics and distribute those metrics across the appropriate applications, sites, servers, and the like, performs shallow analysis on a majority of traffic and deep analysis on a sampled set of the traffic, and estimates network and application performance metrics for the non-deep analysis data, providing an overall estimate of metrics without requiring deep analysis of all traffic.

Abstract: A system is disclosed for manipulating buses and signals on a display window of a graphical user interface of a logic analyzer. Each signal is associated on the display with representations of its sampled data, which may be in the form of lists or of waveforms. The system enables a user to graphically associate the buses and signals. Also, the buses and signals may be visually associated on the display window with user-specified trigger-conditions. The User may graphically associate the signals into buses by selecting the signals then grouping them by selecting a group command. Responsive to this grouping, the system may generate a bus representing the grouped signals. The bus may be graphically associated with the grouped signal-name elements, such as, for example, by a hierarchical structure. The system, responsive to the grouping by the user of the signals into buses, generates bus-data elements representing signal data associated with the grouped signals.

Abstract: A system is disclosed for enabling a user to specify a trigger condition of a signal or bus by enabling the user to graphically select the signal or bus from a hierarchically arranged list of signal or bus names. The user may make this selection from a graphical user interface of a signal measurement system. The user also graphically selects the signal trigger condition. A trigger-specification element identifying the trigger condition is visually associated with a displayed name of the first signal or bus. The user may select the signal trigger condition of the first signal or bus by selecting the first trigger-specification element. The signal measurement system may be a logic analyzer. The hierarchically arranged list may be vertically aligned and each signal or bus name may be visually associated with one of a first group of trigger-specification elements by horizontal alignment.

Abstract: A system is disclosed for enabling a user to specify one or more trigger conditions by graphically creating a pictorial representation of the trigger conditions. The pictorial representation is presented on a display window of a graphical user interface of a logic analyzer and is accomplished using trigger-condition icons. Each icon represents a trigger condition of a signal or bus. The user specifies the trigger conditions by positioning the trigger-condition icons on the display window. The user does this by selecting, dragging, and dropping the trigger-condition icons onto the display window. The display window may include one or more name elements, each associated with a signal or a bus. The user may specify the trigger condition of a first signal or bus by selecting a trigger-condition icon and positioning it at a first position on the display window in horizontal alignment with the name element of the first signal or bus.
