If a BioNomadix wireless physiology signal displays dropout/flatline…
On a single channel
Make sure transducer/lead is firmly inserted to transmitter channel, electrodes are fully adhered, and leads are not pulling
Switch recording channels (both X, Y, and various channels on Receiver)
On both channels
Radio interference is likely disrupting transmission. Try these steps to restore signal quality:
Locate the Receiver/Logger/Smart Center closer to the Transmitter
Charge the Transmitter
Eliminate alternate sources of electrical noise (i.e., cell phones)
Elevate the BioNomadix Receiver/Logger/Smart Center higher in the room
Maintain line of sight to the Receiver/Logger/Smart Center
Participants may inadvertently be blocking line of sight when they move (i.e., scrunch their head to their shoulder). If there’s enough length in the leads, mount Transmitter on the shoulder or upper arm to let more of the radio energy escape the Transmitter.
If the recording environment is near a military base, it’s possible that military-grade RF equipment is interfering; a spectral scan would be required to confirm that and then frequencies could be positioned at quiet points (via BIOPAC Support Request).
Current shipping Firmware can’t be used to change to fixed frequencies on paired BioNomadix Receivers; Loggers and Smart Centers can specify their channels.
Eyes are the window to the soul and, more importantly, the brain. Psychophysiology, neuroscience, and consumer neuroscience researchers use eye tracking technology to understand emotion, behavior, subject response, decision-making, and human performance—and to help improve products and services. But not everyone knows where to start or how and why to use this important technology. A panel of eye tracking experts will present typical use cases and the latest eye tracking technology.
Join this online presentation with Q&A to learn the fundamentals of eye tracking!
Recent physiological studies feature BIOPAC’s Wireless BioNomadix Data Recorders Using Metronomes and Rhythmic stimulation to help people with Parkinson’s disease walk For those living with Parkinson’s disease, even simple tasks can take too long to accomplish properly, such as crossing a room or picking up an object. In this study, participants with diagnosed cases of […]
