Glossary


We try to keep our documentation as readable as possible but it is unavoidable to have to use some technical terms and acronyms. They are explained throughout the various manuals and documents but they are also summarized here alphabetically in case you need a refresher.

ACC
Accelerometer, an inertial sensor that measures acceleration in three dimensions.
AI
Activity index, expressed in g (gravity) units, as derived from an ACC Signal.
BPM
Beats-per-minute, typically used as a unit for HR.
BrPM
Breaths-per-minute, typically used as a unit for RR.
Byteflies Cloud
A secure data storage and processing system for data recorded by Sensor Dots.
Byteflies Kit
The collective name for all components of the CE medical device and its accessories.
Channel
A Sensor Dot can record two biopotential Signals simultaneously and has two pairs of electrode connectors that each form a Channel.
Docking Station
A component that can charge up to 5 Sensor Dots and provide a secure communication gateway to the Byteflies Cloud to upload recorded data.
ECG
Electrocardiography, a biopotential measurement of the electrical activity of the heart.
EEG
Electroencephalography, a biopotential measurement of the electrical activity of the brain.
EMG
Electromyography, a biopotential measurement of the electrical activity of a skeletal muscle.
EOG
Electrooculography, a biopotential measurement of eye movement.
ExG
Any biopotential signal.
Group
A Group combines one or more Docking Stations that are assigned to a specific study.
GYR
Gyroscope, an inertial sensor that measures angular velocity in three dimensions.
HR
Heart rate, expressed in beats-per-minute, as derived from an ECG Signal.
IFU
Instructions for Use, a user manual for a medical device.
IMU
Inertial Measurement Unit, referring to the combination of ACC and GYR to record motion-related information.
Patient ID
A unique string used to identify a study subject.
Patient Record
A list of pre-configured Patient IDs and the hardware they are associated with.
Recording
The combination of all data recorded by a single Sensor Dot is grouped in a Recording.
RR
Respiratory rate, expressed in breaths-per-minute, as derived from an ECG Signal.
Sensor Dot
A 2-channel biopotential and tri-axial inertial measurement device, indicated for recording electroencephalography (EEG), electrocardiography (ECG), electromyography (EMG), electrooculography (EOG), acceleration (ACC), and angular velocity (GYR).
Sensor Patch
An interface between Sensor Dot and the body.
Signal
A physiologic or motion signal, as recorded by a Sensor Dot (e.g. ECG).
User Account
A Byteflies Cloud account that can contain one or more Groups and can only be accessed with a specific username and password.
