enhances the flexibility of the data by allowing users to compare data to studies which use different
filter techniques or accumulation sizes (e.g., 1 second epochs versus 60 second epochs).

Water Resistance
wGT3X-BT devices are water resistant in accordance with IEC 60529 IPX7, or immersion in one (1) meter
of water for up to 30 minutes
Wireless
In addition to the standard features and functionality of their predecessor devices (wGT3X+ and
wAc), the wGT3X-BT provides a wireless interface by way of Bluetooth Smart
TM
wireless
communication protocol. This 2.4 GHz based interface allows for interoperability with millions of
already fielded nodes as well as provides a means of rapidly gathering device and/or subject
information. The wireless functionality can be disabled when not needed in order to increase battery
life.
Heart Rate
By way of Blue Tooth Smart chest straps, the Moses is capable of measuring and storing both standard
heart rate in Beats Per Minute (BPM) format as well as providing R-to-R measurements thus enabling
the researcher to better understand heart the subject’s activity profile.
Wireless Reporting and Control
In addition to enhancing and increasing the sources for data collection, the wireless functionality of the
wGT3X-BT enables the user to perform many functions that previously required USB connection or
weren’t possible before. Many functions can now be performed in the field rather than requiring the
researcher to be tethered to a computer in the lab.
Initialization
The wGT3X-BT can be fully initialized wirelessly. This can be performed with ActiGraph’s new ActiLife
Mobile available on the iPhone platform.
Device Status
Device specific status information can be obtained. Some of the items retrieved include; firmware
version, battery voltage, current mode, subject name, and device serial number.
