Motion and Environmental Artifact Reduction-
• Shear-isolated, Constant-Pressure EEG Electrode Mount
• Common-mode follower
Long-term Comfort
-
• Designed for comfort and ease of use
• Absence of skin abrasion and gels eliminates skin irritation
• Through Hair design -
What does this technology enable?
-
• Long-term comfort
• Maintenance of contact
• No skin abrasion or preparation
• Low noise
• Reduced motion artifacts
• Ambulatory recording -
Are your products FDA approved?
-
Not yet. While our systems are designed towards ANSI safety
standards, neither the DSI 10/20 nor the PSM are FDA approved
systems. We plan to develop an EEG system further towards
FDA approval through our spin-off Advanced Neurometrics
Inc (ANI link
), but in the meantime, both the DSI 10/20 and PSM can
be used for research on human subjects, as they have been
deemed “minimal risk devices” by several IRBs

What future developments are expected?
-
• 24 channel digitizers are in the plans for future development,
but timeline depends on funding
• New headset designs with fewer electrodes
• We have a few other improvements in R&D to look forward to in the years to come, unfortunately, we cannot disclose those yet, please check again next year, or email us to put you on our mailing list -
DSI 10/20 has 21 sensors but only a 12 channel digitizer?
-
• DSI 10/20 can be configured with anywhere from 3 to
23 sensors.
• In headsets with more than 12 sensors, a junction box is included on the headset. This user-configurable junction box enables the user to select which 12 sensors they wish to digitize at a time. -
When is Quasar USA ready to fill orders?
-
• DSI 10/20 prototypes are reliable and fully functional.
• We are selling prototype DSI systems in small volumes for research applications.
• We are ready to take orders now. Please contact us to request a quote. -
What is the lead time on orders?
-
• That depends on quantity and our pipeline at time of
purchase.
• A delivery date is provided at time of purchase. -
Can I lease equipment?
Yes, we are considering a monthly leasing plan depending on system availability
