The F1 System

The F1 System consists of hardware and software connected wirelessly.

The F1 Software and the F1 Wrist Marker are connected to the F1 Cap . “F1 Lab” is a desktop application designed to be used by
medical professionals (neurologists, doctors, analysts) to record data. F1 Lab also provides tools for the user to perform in-depth analysis of recorded data. “F1 Home” is a tablet application that allows patients to easily record EEG in the convenience of their own home. The data recorded on the tablet can be copied to the medical professional’s computer and analyzed with “F1 Lab.”

Product Components

The EEG hood set contains: three sizes of the “F1 cap” including exchangeable dry electrodes (“F1 electrodes”), the “F1 amplifier” with exchangeable battery, three electrode cables for attaching external disposable electrodes (twice reference mastoid, once heart rate), “F1 wristband marker”, laptop with software “F1 Lab” and tablet with Android app “F1 Home”.

Cap

Up to 40 channel EEG device designed for medical or research application.
The cap is made of biocompatible materials, including silicone. In addition to the forehead electrodes integrated in the hood and the three electrode cables attached to the cap, 31 electrode slots allow the electrodes to be placed evenly on the surface of the head. A full 10-20 coverage is thus given. The F1 cap connects directly to the F1 amplifier using a dedicated bracket.

Amplifier

With replaceable battery suitable for long-term recording.

The amplifier is used to convert the measured currents into digital signals. These are transmitted to the PC via a WLAN connection and stored in parallel on the integrated memory. The WLAN connection is established via a separate network, which is set up by the amplifier itself and to which only the F1 Lab or the F1 Home software can connect. The amplifier also contains an RF receiver, which can receive the markers sent by the wristband and embed them into the EEG data.

Wrist Marker

Wrist marker for marking noteworthy time points while recording.

If the patient wants to send a marker during a recording, e.g. (B) in case of dizziness or to draw the doctor’s attention to a part of the recording, the bracelet marker can be used to send a marker by pressing the button shown in the figure below. This is embedded synchronously in the recording. The bracelet marker designed to be worn like a watch.

Electrodes

Patented Dry Electrodes
The patented dry electrodes contain a spring mechanism that adapts to the head automatically. They are held magnetically in the electrode slots in the cap and can be replaced, desinfected and installed again in a fraction of time.

Tablet

Easy to use app on the dedicated tablet to have an overview about placement of the electrodes.

F1Lab software for the laptop allows patient registration, recording, playback of the EEG, and reporting. The recording is stored by the amplifier and transferred to the laptop via WLAN. If the laptop is in the vicinity (e.g. in the practice), the transmission is live. Otherwise (e.g., if the cap is used in the patient’s home), the recording is transmitted at a later time.

The EEG recording and measurement of the contact resistances can be performed both via the laptop (e.g. measurement in the practice) and via the tablet (in simplified form by the patient).

The Software Kit

The F1Lab software for the laptop enables patient registration, recording and playback of the EEG and diagnosis. The recording is saved by the amplifier and transferred to the laptop via WLAN. If the laptop is nearby (eg in the practice), the transmission is live. Otherwise (eg when using the hood at the patient’s home), the recording is transmitted at a later point in time.
The EEG recording and measurement of the contact resistance can be carried out both via the laptop (e.g. measurement in the practice) and via the tablet (in a simplified form by the patient).
