Ultium EMG Hardware User Manual9(Rev J)3.2 Glossary of TermsUltium ReceiverUltium ReceiverUltium ReceiverUltium Receiver – A USB-connected Receiver which receives signals from one or more EMG sensors.UltiumUltiumUltiumUltium----EMG SensorEMG SensorEMG SensorEMG Sensor -- A small individual radio transmitter typically worn on the body used to measureand transmit bio-potential signals (such as EMG) or motion related signals (such as position oracceleration). The Ultium System can accommodate up to 16 body worn EMG Sensors in one network.UltiumUltiumUltiumUltium----EMGEMGEMGEMG SmartLeadSmartLeadSmartLeadSmartLead – An accessory sensor that can be connected to an EMG sensor to provideother biomechanical signals. Examples include force, acceleration, etc.UltiumUltiumUltiumUltium----EMG Serial NumberEMG Serial NumberEMG Serial NumberEMG Serial Number – A unique five-character tag used to identify each EMG Sensor. Themembers of any Ultium network are determined by their serial numbers. Smart Lead Types are groupedinto a predefined range of serial numbers. Thus, by serial number the Ultium system can automaticallydetermine the type of signal parameter being transmitted from any Sensor in the network.MultiMultiMultiMulti----Channel SensorChannel SensorChannel SensorChannel Sensor – Certain Sensor Types provide more than one signal. Thus, a Multi-ChannelSensor behaves like two or three standard Sensors. An example is a 3-D Accelerometer that providesacceleration data for the x, y and z directions.ProbeProbeProbeProbe – A generic term for any EMG Sensor.RFRFRFRF – (Abbreviation for Radio Frequency) Wireless communication takes place on assigned radiofrequencies or channels. For the Ultium System, RF transmissions occur at frequencies between 2.4GHz and 2.5 GHz. Other wireless systems including WiFi and Bluetooth commonly operate at the samefrequencies and can be a source of interference.RF NetworkRF NetworkRF NetworkRF Network – RF transmissions for the Ultium System can be selected to occur on one of 4 differentnetworks. All networks use frequency hopping to avoid interference.RF TrafficRF TrafficRF TrafficRF Traffic – The presence of radioactivity present on a given frequency similar to the number of carson an expressway. Several users (wireless devices) may be communicating using the samefrequencies. Best operation of the Ultium System occurs when the RF Traffic is low.
