Dynamic Change-Point Detection (DCD) 
 

 PDF Version

A method for detecting statistically significant changes in data with a wide array of applications and uses.

The U.S. Navy seeks to commercialize a suite of patents related to Dynamic Change-Point Detection based on U.S. Patent 5,671,734 (Automatic medical sign monitor).

The Technology

Dynamic Change-Point Detection (DCD) can detect in real time whether or not there is a signal (e.g., a change in economic conditions or a health status change) and whether the signal has come to an end. DCD can also detect various characteristics and features of the signal.

Application

DCD is currently used in government hospitals as part of the Medical Data Surveillance System, which gives doctors an unprecedented look into patients’ health and changing conditions. DCD also can be applied to many other applications, such as market-trend analysis and reporting, sales forecasting and analyzing, and system monitoring.

Key Benefits

From the first data point on, this method:

  • Calculates test statistics
  • Flags and color-codes trends, shifts, and outliers
  • Estimates signal length, initial starting point, and ending point
  • Dynamically adjusts baseline and threshold values
  • Reconstructs the signal
  • Displays results
  • Estimates baseline and threshold values from the incoming data
  • Detects shifts and trends within the data
  • Development Status

  • U.S. Patents issued: 5,671,734, 7,297,113, 7,383,071, 7,474,985; and U.S. Patent Applications pending: 10/655,631,10/827,206.
  • Total R&D: 15 years
  • DoD 5000 Series TRL 9: Actual system proven through successful mission operations
