HP Mobile Calculating Laboratory ® The HP Mobile Calculating Laboratory (HP MCL) consists of one or more Fourier sensors, an HP StreamSmart 410, and an HP 39/40gs 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.

StreamSmart 410, connect the StreamSmart 410 to the HP 39/40gs serial port, (press the StreamSmart 410 ON button if the green light is not illuminated) and then press the START menu key. When you start the StreamSmart Aplet and press the START menu key, you will find that you are immediately streaming data from all of the sensors.

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 410. 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.
Table 2-2 lists the menu functions available during and just after streaming. Table 2-2 Streaming menu keys, 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.
Zoom, Pan and Trace are radio button toggles that work in conjunction with the direction keys ( , and ). Only one function is active at a time, its active status indicated by a small square after the function name. For example, TRACqqq! means the tracer is active and the direction keys will be used to trace the selected stream or jump to another stream.
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 point as a row in your chosen columns in the Statistics application. These functions are found on the second page of the Stream menu, which is only active once streaming has stopped.
(ã) the battery symbol appears in the upper left corner of the screen, as shown in Figure 2- 1 0, be sure to charge the StreamSmart 410 as soon as possible. See Chapter 1 for instructions on charging the battery.
Export menu. Figure 2- 1 2 The Export Menu There are six fields in the Export menu: four for the StreamSmart 410 channels, one for the timestamp associated with each data point, 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.
The Statistics Aplet lets you view your data in a table, plot it as a graph, view summary statistics, and create 2-variable models for bi-variate data. All of this functionality is described in detail in your HP Calculator’s user guide, so it is not repeated here. However, this section contains a brief summary of commonly used functions in the Statistics Aplet.
The views of the Statistics Aplet are summarized in Table 2-8 and Table 2-9. For more information, please refer to your HP Calculator’s user guide. Table 2-8 Views in the Statistics Aplet...
Capturing Data from Events Although the StreamSmart 410 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 rates 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 410. The readings will be auto-numbered, and this number will be stored in Row 1 of column C1 in the Statistics application.
Like the Export menu discussed in Chapter 2, the Capture Events menu has a field for each of the four StreamSmart 410 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 application column for storing the data from that channel.
In Figure 3-7, C2 is highlighted as the destination for data from the sensor in Channel 2 of the StreamSmart 410. Pressing !sgsy]!!CHK! now will deselect Channel 2 for exporting data. 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.
(e.g., 3 seconds exactly) and collect a particular number of samples (e.g., 50 samples). The StreamSmart 410 accommodates this need via the Experiment option under the Views menu, as illustrated in Figure 3- 1 2 and Figure 3- 1 3.

Once it has been determined that software calibration for a sensor is the only option, it should be noted that the StreamSmart 410 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.

Filtering data for display and export Under most circumstances, each pixel in the display of the data stream represents multiple sensor readings. Depending on the current window, each pixel could represent quite a large data set. For example, in Figure 4-22, each pixel has a width of approximately 0.1 seconds (13s/130pixels=0.1s/pixel).
methods. Once a filtering method is chosen, it is used for the current (as well as future) data streams until either the StreamSmart Aplet is reset or another filtering method is chosen.

Data history By default, StreamSmart 410 collects data from a single sensor at approximately 5,000 samples per second while streaming. At this rate, the StreamSmart Aplet can collect approximately 16.5 seconds of data before memory is full. You can use...
Oscilloscope mode While streaming data in the Plot view, the StreamSmart Aplet provides you with the option of Oscilloscope mode. Press SCOPE to activate Oscilloscope mode. This menu key is a toggle, so press it again to return to normal data streaming. Oscilloscope mode works with a trigger to enable an oscilloscopic view of your data stream.
StreamSmart 410 to an audience or in a classroom setting. You can also demonstrate an experiment in this way. The StreamSmart 410 connects to a computer using a mini-USB to USB cable. This cable came with your HP 39/40gs graphing calculator. Connect the StreamSmart 410 to your computer, launch the HP 39/40gs Virtual Graphing Calculator application, and start the StreamSmart Aplet.
Keyboard shortcuts Table 4-5 lists the keyboard shortcuts for the StreamSmart Aplet. These shortcuts are available either during or just after streaming. Table 4-5 Keyboard shortcuts Key(s) Description Toggles through the three options available for viewing a final data set after streaming and prior to export.
