  • Page 7: Hp Mobile Calculating Laboratory

    ® The HP Mobile Calculating Laboratory (HP MCL) consists of one or more Fourier sensors, an HP StreamSmart 400, and either the HP 39gs or HP 40gs graphing calculator with the StreamSmart Aplet. Investigation and understanding of mathematics and science concepts are enhanced by the HP Mobile Calculating Laboratory, as it is designed to simplify the collection and analysis of real-world data.

  • Page 11: The Statistics Aplet

    The Statistics Aplet The StreamSmart Aplet works seamlessly with the Statistics Aplet to provide you all the tools you need to collect and analyze data. StreamSmart does the collection of the data and selection of a final data set for analysis, then exports the data directly to the Statistics Aplet, where additional graphing and analysis occurs.

  • Page 12: Helpful Hints

    The StreamSmart Aplet also employs dialogue boxes from time to time, as shown in the Streamer Plot Setup view in Table 1-2 above. The field names in menus and other data are shown in bold type. For example, in the top left corner of the Plot Setup dialog box in Table 1-2, there is a field named XRNG.

  • Page 16: Viewing A Stream Of Data

    Viewing a stream of data Once the StreamSmart Aplet is started with one or more sensors and the StreamSmart 400 attached, the StreamSmart Aplet displays a graphic representation of the incoming data streams as time graphs. The horizontal dimension represents time in seconds, and the vertical dimension represents the current sensor values in relevant units.
  • Page 17 Topics. Although the data are averaged for graphing purposes, you still have access to all the data. This is a unique feature of the StreamSmart 400. The screens shown in Figure 2-7 and Figure 2-8 illustrate the location and basic functions of the menu keys during and just after streaming.
  • Page 18 Table 2-2 lists the menu functions available during and just after streaming. Table 2-2 Menu keys during data streaming, page 1 Menu Key Description This menu key opens the channel selection menu, which allows you to \CHAN select which stream to trace. By extension, you are also choosing which stream to zoom or pan vertically.
  • Page 19 Table 2-3 Functions controlled by the direction keys Menu Key Description • Use these keys to zoom in or out horizontally • If you are actively streaming data, these keys speed up @ZOOM! the stream or slow it down • If streaming has stopped, trace to data of interest and then switch to Zoom to zoom in or out on the tracer coordinates.
  • Page 20 Besides navigating and tracing the data set to find data of interest, StreamSmart also lets you compare any two points in a single stream and manually add a data- tuple as a row in your chosen columns in the Statistics Aplet. These functions are found on the second page of the Stream menu, which is only active once streaming has stopped.

    Export menu. Figure 2-12 The Export menu There are six fields in the Export menu: four for the StreamSmart 400 channels, one for the timestamp associated with each data-tuple, and one that determines what happens after the data is exported. The four channel fields, (CH 1, CH 2, CH 3, and CH 4), as well as the TIME field, all behave the same way.

  • Page 27: Capturing Data From Events

    Capturing Data from Events Although the StreamSmart 400 is capable of collecting data at high sampling rates, as shown in Chapter 2, it is also versatile enough to gather data from experiments of slower frequency—and even distinct events—with ease. You have seen the power of streaming data in real time at speeds over 5,000 samples per second with the streaming experiment.

    By default, pressing the %ADD$ menu key will capture the current set of readings from sensors attached to Channels 1 through 4 of the StreamSmart 400. The readings will be auto-numbered, and this number will be stored in Row 1 of column C1 in the Statistics Aplet.
  • Page 31 Like the Export menu discussed in Chapter 2, the Capture Events menu has a field for each of the four StreamSmart 400 channels. Each of these fields is preceded by a checkbox to activate/deactivate the channel, and followed by a choose box to select the Statistics Aplet column for storing the data from that channel.

  • Page 32: Monitor And Select Events

    In Figure 3-7, C2 is highlighted as the destination for data from the sensor in Channel 2 of the StreamSmart 400. Pressing !sgsy]!!CHK! now will toggle Channel 2 to be inactive. Pressing the CHOOS menu key drops down a list of C1 through C9, and C0, from which you can choose any other column for the data from the sensor in Channel 2.

  • Page 33: Analyze The Data

    Under certain circumstances, it is desirable to run an experiment for a particular duration (e.g., 3 seconds exactly) and collect a particular number of samples (e.g., 50 samples). The StreamSmart 400 accommodates this need via the Experiment option under the Views menu, as illustrated in Figure 3- 1 2 and Figure 3- 1 3.

    The StreamSmart Aplet is designed to automatically identify a Fourier sensor attached to the StreamSmart 400. In some cases, StreamSmart may fail to identify a sensor or identify it incorrectly. In this case, you must manually identify the sensor and select the Sensor Setup using the Sensor Setup dialog box.

  • Page 36: Unit Setup: Manually Select Units For A Sensor

    Figure 4-3 Figure 4-4 Figure 4-5 Unit setup: manually select units for a sensor When the StreamSmart Aplet automatically identifies a sensor, it also chooses a unit of measurement for that sensor. All subsequent readings from that sensor are shown using the current unit of measurement. Many, but not all, of the probes have multiple units of measurement available.

  • Page 37: Calibration

    Once it has been determined that software calibration for a sensor is the only option, it should be noted that the StreamSmart 400 offers both 1-point and 2-point methods for such calibrations. A 1-point calibration simply changes the offset, while a 2-point calibration changes both offset and slope.
  • Page 38 Figure 4-10 Figure 4-1 1 Figure 4- 1 2 shows the calibration screen, with its options for 1- or 2-point calibration. Note that the meter continues to show the live streaming of sensor values. Press to enter the correction for the current reading. The current reading is still 6.408, but it should read -6.433.

  • Page 39: The Plot Setup Menu

    The Plot Setup menu The Plot Setup menu gives you access to a number of advanced options for streaming experiments. Among these are overriding the default streaming window settings and the default data filtering methods. Setting the stream window In most cases, you will use the zoom and pan features to match the display dimensions to the set of data points you find interesting.

  • Page 40: Plot Display Options

    Plot display options When performing experiments with multiple probes, the StreamSmart Aplet places each data stream in its own swim-lane by default. The data streams appear in the numerical order of their channels, from top to bottom of the display. Under certain circumstances, you may want to see multiple data streams superimposed instead of separated in swim-lanes.

  • Page 45: Streamsmart 400 And The Virtual Hp 39/40Gs

    The StreamSmart 400 may be used in conjunction with the virtual HP 39/40gs Graphing Calculator software for the PC. This use is effective when demonstrating the StreamSmart 400 to an audience or in a classroom setting. Students can also demonstrate an experiment to the class in this way. The StreamSmart 400 connects to a PC using a mini-USB to USB cable.
