UniTrigger System
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.

Datasheet
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.
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.

System Introduction
Using Neuroguide for Neurofeedback and QEEG (Old Model)
P300 Speller using OpenViBE
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.
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:
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.
