All that is required is adding a housing and electrodes and the system is ready to be used in real world applications. The LNDSP17 is meant to be used with Linear Dimensions’ PEAL system which provides a variety of tools for acquisition, interrogation, analysis and fusion of measured data. Custom dashboards may be created and reside on a local display using the on board microcontroller (TPS430), or may reside on a mobile, tablet, PC device. Alternatively, Linear Dimensions’ Cloud service may be utilized to peform customized extraction, analysis and fusion of data. PEAL provides OEMs the ability to differentiate and utilize measured data in their own way to provide value in their specific application spaces. Customize fusion & fashboards available. An example PEAL implementation is shown in Figure 1 and Figure 3. The signal was being acquired from a human arm, a very difficult place to acquire signals. The PEAL algorithms were able to cut through noise from motion and location artifacts even though the noise was hundreds of times larger than the signal of interest and had content in the same spectrum. In fact the heart waveform shown below was captured from an arm even though its magnitude was <50uV, and an athlete was running at full speed (>8 miles/hr). His arms were swinging, electrodes were connecting and disconnecting, 60Hz signals and EMI from the running track were radiating and being coupled into the SP17 device. The muscle noise amplitude was much greater than the heart rate amplitude producing interference in the same spectrum as the heart rate waveform. Additionally, the baseline would move around, regularly saturate and then recover. The result from the PEAL system after filtering, baseline extraction, and adaptive filtering is shown below. No heart rate was discernible from the data with the naked eye prior to providing the signal to the system. The heart signal below was combined with other data to produce customized fusion data for customers. Figure 3 – An example of a fusion measurement made by the SP17/PEAL combination is shown above. A heart waveform is acquired from an extremely small heart waveform surrounded by a very noisy signal infected with multiple noise sources. Red plus signs indicate identification of beat by PEAL.
