MxEncoder
The MxEncoder, Figure 7, is the impact sensor and wireless radio worn
by the athlete. Each MxEncoder is installed in a player’s helmet and
contains six single-axis ±250g accelerometers that record head impacts
as they occur and transmit that information in near real-time to the
Sideline Controller. MxEncoders are designed to fit comfortably within
the helmet with no modifications needed, and to retain the NOCSAE
certification as installed.
A 3.6V rechargeable NiMH Battery Pack, Figure 8, is used in each
MxEncoder and typically holds a charge for one week during normal use.
IMPORTANT: Only SRS MxEncoder Battery Packs should be used to power
MxEncoders
The MxEncoder has an automatic On/Off switch that turns on once the helmet is
placed on the player’s head and shuts off when the helmet is removed. The switch
uses proximity based sensing that determines when there is a head in the helmet.
A hand may also be used to turn the switch on. The switch automatically turns off
the unit after it no longer senses the presence of a head in the helmet.
MxEncoders must be installed in the appropriate model/size helmet according to
the chart below.
