# Features

# Handles different types of data

  • continuous signals e.g. ECG, acceleration, thoracic impedance, etc.
  • events e.g. trigger annotations, artifact regions, etc.
  • values e.g. blood pressure, respiration rate, heart rate

# One or more simultaneous channels may be recorded

  • e.g. multi channel ECG
  • e.g. diastolic and systolic blood pressure
  • e.g. three axial acceleration sensor data

# Simultaneous, synchronous storage at different sample rates

  • e.g. acceleration data at 80 Hz
  • e.g. ECG at 200 Hz

# Multiple sensors of one type may be recorded

  • e.g. one ECG sensor for dry electrodes and one for adhesive electrodes
  • e.g. multiple acceleration sensors with different locations

# May be easyly used in embedded systems

  • simple way for writing data
  • variable byte order (little endian, big endian)
  • support of multiple data types e.g. int32, uint16, double, etc.
  • no unit conversions are necessary

# Sample-exact data access

  • different time bases for different entries possible
  • access via sample stamp

# Support of different file formats

  • binary files, CSV files, XML files projected

# Reference implementation in Java

  • no dependency to commercial software
  • little platform dependancy
  • easy integration in MATLAB®

# Human readable meta file

  • XML format
  • readable in every browser or editor

# Separation of meta information and data

  • one meta file (header file) and one or multiple data files
  • easy opening of data files with 3rd-party software

# Direct data access possible

  • data access without unisens library is possible

# Flexible way for data organisation

  • free comments
  • data can be arragned in logical groups
