DataLITE

DataLITE is a range of professional wearable tech systems allowing the user to collect physiological data from a wide variety of sensors while the subject is free to move in almost any environment.

DataLITE provides a selection of three interfaces. Each is capable of recording up to 24 analogue and 12 digital channels of data. If more is required, two or more interfaces can operate in the same environment.

DataLITE EXPLORE is a wearable device that provides multi-channel recordings of EMG, dynamic joint movement, acceleration and other physiological parameters from a range of wireless sensors. This provides data capture & analysis both within and outside the boundaries of normal testing environments.

  • Fully portable wireless data recorder
  • Real-time data display as graphical traces or engineering units
  • Optional real-time data acquisition & analysis to the PC

DataLITE ADVANCE is a desktop unit incorporating all the same features of PIONEER with the addition of analogue outputs for each channel of wireless data. This standard analogue output is easy to interface to and provides the user with a very simple, accurate and robust way of sending data to 3rd party systems.

  • 24 analogue and 12 digital sensor outputs
  • Readily transfer DataLITE sensor data to 3rd party devices including camera-based motion capture systems
  • Known exact latency of 100 mS delay to a 3rd party instrument
  • ADVANCE may be disconnected from the PC, allowing it to be used solely as an analogue output unit. This provides a very robust, novel product which may be used independent of the PC

DataLITE PIONEER is the basic interface utilizing a dongle wireless transceiver to communicate between DataLITE sensors and the computer. Data is displayed and recorded directly to the PC or streamed to third party software. Data can be analysed in the Biometrics Analysis Software or exported for analysis in other software.

  • Communicates with up to 24 channels of DataLITE sensors
  • A typical work environment will give up to a 30m working range
  • Several DataLITE systems may be set up in the same working environment
  • Available as a non-medical or certified medical device

DataLITE uses progressive frequency hopping, error detection and data recovery algorithms. This allows the readings to be smooth and robust even in the typical modern work environment which utilises many different types of Wi-Fi products.

Communications between a DataLITE interface and sensors use 4 frequencies out of a possible 32; these are evenly spaced in the range of 2.403 GHz to 2.480 GHz.

DataLITE wireless sensors convert input signals such as joint angle, EMG or force data and transmits in real-time to the PC for analysis. This produces a versatile and expandable design with the greatest possible accuracy, negligible drift and the greatest freedom for the test subject.

RF Channel Optimisation Test

A new RF Channel Optimisation Test is an easy way to detect errors on all 32 frequencies available to DataLITE and determine the optimum combination of RF Channels to use.

DataLITE communications use 4 frequencies out of a possible 32 within the range of 2.403GHz to 2.480GHz; the choice of 'RF Channel' number selects which 4 to use.

Because this frequency range is also used by many other devices, such as Wi-Fi and mobile phones, there is a good chance that if the distance between the Dongle and associated sensors is significant, some communications will be lost due to another device transmitting on the same frequency. DataLITE devices reduce the effect of interference by continuously frequency hopping between 4 frequencies using built in error detection and data recovery.

The RF Channel test performs multiple transmissions of data on all available frequencies in sequence without using any error correction. A result of 100% means that all data transmissions on that frequency have been successfully transmitted and received. The ideal 'RF Channel' to use would be one where all 4 frequencies used by that RF Channel are 100%.
