UniTrigger System

UniTrigger Diagram                     

Any serious EEG system needs the ability to send accurate and precise time markers for triggers and events. Although wireless systems enable mobility, accurate timing is difficult due to the inherent latency and jitter in wireless communications. This lack of accuracy is present in all standard wireless EEG solutions. The Cognionics UniTrigger system is created to accurately broadcast time markers with millisecond precision, resolving the issues of latency and jitter. Because the timing accuracy is guaranteed in hardware, there is no need for software or algorithmic timing compensation making experiments simple and reliable, just like a traditional wired setup.

The UniTrigger system is compatible with any EEG headset with a DB-25 connector running at 600hz and computer that can interface using DB-25. The receiver is battery powered, whereas the transmitter can be powered through microUSB or using a battery.

Quick-30 Dry EEG Headset

The Quick-30 is the latest in mobile EEG technology, offering an unmatched level of usability and signal quality to enable new research applications. With the Quick-30 system, EEG signals can be obtained on most subjects in just under one or two minutes. The headset positions 30 active electrodes in an extended 10-20 array.

 Cognionics Quick-20 Dry EEG Headset

High Signal Quality

Measuring EEG signals in real-world environments is tough. Unlike a controlled laboratory environment, electrical noise from power lines, computers and other devices can easily overwhelm a conventional, unshielded EEG system. In addition, subject movements can also easily induce large amplitude electrical and physical noise to overwhelm the tiny EEG signal. To make real-world EEG acquisition, possible, the Quick-20 uses a highly optimized combination of sensors, mechanics and electronics to eliminate unwanted artifacts.

  • Combination of active electrodes and active shielding

  • Resistant against electrical and movement artifacts

  • Real-time measurement of sensor impedance

  • Research-quality EEG amplifier: 24-bit ADC, low-noise, high dynamic range inputs with flexible configuration of sample rates, bandwidth and channels

Fast, Easy and Mobile

The Quick-30 is a complete portable EEG system in a wearable, lightweight package. Data can easily be streamed wirelessly via Bluetooth or recorded to a microSD card.

  • Low-noise dry electrodes that require minimum prep and no clean-up

  • Fully wireless: no cords for data recording or triggering

  • Comfortable without any restrictions on subject movement

  • Lightweight and wearable

Versatile

Like all Cognionics, the Quick-30 is designed to interface with all of the hardware and software tools necessary for advanced neuroscience research.

Cognionics Software Development Support and API

All of our systems are designed to provide easy and unrestricted access to the raw, unfiltered EEG data stream. This not only makes it easy to do advanced research but to also build new applications. To make the development process easy, we offer two paths at no cost.

 

LabStreamingLayer Real-time Output

Our acquisition software includes built-in support for the open-source LabStreamingLayer (LSL) platform, developed by UCSD. With LSL, you can set our acquisition software to act as a data server with a click of a button. Client applications can access the real-time EEG stream locally or across a network. This model makes it easy to prototype new applications and signal chains while still retaining access to the advanced capabilities (e.g., impedance check, device configuration) of our software. Specific features include:

  • Multi-language support: C, C++, C#, Java, Python and MATLAB
  • Easy-to-use: setting up a LSL inlet takes just a few lines of code
  • Well documented API and example code
  • Real-time data accessibly locally and across a network
  • Precision timing and integration with other hardware (e.g., inputs, eye trackers, motion capture)

 

Direct Hardware Access

For building completely custom applications on new platforms, we can provide the technical details to interface directly with the hardware. Most Cognionics systems use a Bluetooth or USB connection and applications can developed on most platforms (Windows, Linux, Mac OS X, Android) that support one or the other.
