LXSOFTWARE FEATURES

  • Compatible with Windows Vista, Windows 7, 8, and 10
    • Mac support is also available via Parallels® or another virtualization software.
  • New Respiration Line Excursion (RLE) Tool
    • The RLE tool measures the ratio of the relevant response divided by the comparison response and produces a suggested pneumograph score. As the examiner selects a relevant question, the tool normalizes it to all other questions on the chart and displays the R/C measurement ratio.
  • New ESS Report Generator
    • Uses scores from the manual score sheet to formulate a printable report and summary conclusion paragraph to describe the test results of event-specific and multi-issue exams.
    • Report includes both a categorical result and a statistical classifier in the form of a p-value, confidence level or odds ratio, and also includes the manual scores and information about test accuracy.
  • PLE Pulse Amplitude Tool
    • A virtual sensor derived from the PPG sensor providing a visual comparison of the pulse amplitude changes in the PPG data around the question onsets.
  • EDA Design (6) EDA choices (GSR or GSC - Tilt table, detrended, and automatic)
    • Supports the LX5000 GSR or GSC modes
    • Automatic: classical high-pass filter solution to EDA signal processing. Attempts to keep the trace centered on a common baseline.
    • Manual: examiner is in charge of controlling the sensor trace via centering, sensitivity, and slope adjustments. The slope may be adjusted via a slider control under the sensor arrow.
    • Detrended: hands-off solution with extremely high correspondence with the manual EDA. Attempts to keep the trace centered on a common baseline, but the sensor trace is not permitted to dip below its corresponding sensor arrow.

PolyScore Note
APL has removed PolyScore's compatibility with Windows Vista and older. Due to security and functionality concerns, Lafayette Instrument advises Vista users to upgrade to at least Windows 7 before the end of Microsoft Vista extended support in April 2017.
