Linear Force SmartLead
2.2 Glossary of Terms
Ultium Sensor -- A small individual radio transmitter typically worn on the body used to measure
and transmit bio-potential signals (such as EMG) or motion related signals (such as acceleration).
The Ultium Systems can accommodate up to 16 body worn Ultium Sensors in one network. Two
Ultium Systems may be used in parallel, on separate RF networks, to accommodate up to 32 body
worn sensors.
Ultium SmartLead – Refers to different data collection modalities. Each SmartLead measures a
given type of physical parameter. Different SmartLeads can be combined in the same Ultium
network. The most common Ultium SmartLead is EMG. Examples of other types include
Accelerometers, Goniometers and Force sensors.
Ultium Serial Number – A unique five-character tag used to identify each Ultium Sensor or Ultium
Smartlead. The members of any Ultium network are determined by their serial numbers. Also,
Ultium Sensor Types are grouped into a predefined range of serial numbers. Thus, by serial number
the Ultium system can automatically determine the type of signal parameter being transmitted
from any Ultium Sensor or Ultium SmartLead in the network.
Multi-Channel Sensor – Certain Ultium Sensor Types provide more than one signal. An example is
a 3-D Accelerometer that provides acceleration data for the x, y and z directions.
