Trigno™ Wireless Biofeedback System- 9 -Trigno System OverviewThe TrignoTM Wireless Biofeedback System is a device designed to make EMG(electromyographic) and biofeedback signal detection reliable and easy. Thesystem transmits signals from the Trigno Galileo sensors to a receiving basestation using a time-synchronized wireless protocol which minimizes datalatency across sensors. The core architecture of the Trigno System is designedto support high fidelity EMG signals, along with complementary biofeedbacksignals such as movement data, force signals, contact pressure events andtiming and triggering information. For mobile biofeedback applications, TrignoGalileo Sensors can communicate with Bluetooth BLE 4.2 compliant hostdevices. The system is also capable of integrating with 3rd party lab equipmentthrough a variety of interfaces whichinclude analog signal generation,triggering scenarios and digitalintegration through the Trigno SDK(Software Development Kit) and theTrigno API (Application ProgramInterface). Refer to the specificcomponent sensor User Guides foroperational details of these systemelements.Trigno Galileo Sensor FeaturesEach Trigno Galileo Sensor is equipped with the following capabilities anddesign features: on board precision 4-channel EMG sensor built-in 9-axis inertial measurement unit (IMU) Dual Mode “BLE-Base” communication Onboard RMS and Mean calculations Onboard orientation calculation Onboard median frequency calculation software selectable operational modes inter-sensor latency < 1 sample period wireless transmission range 20+m1 self-contained rechargeable battery battery charge monitoring and status indicator environmentally sealed enclosure low power mode auto shutoff internal magnetic switch LED User Feedback1.
