BODYGUARDIAN CONTROL UNIT – BASE KIT Operator Manual

4.2 OPERATIVE MODES
The Bodyguardian Control Unit can be configured to run in different operative
modes depending from the conditions (i.e. presence of Bluetooth connection with
an Associated Device, configuration settings received, etc.) as described below:
IDLE Mode: is when the Bodyguardian Control Unit is powered ON and it is
waiting to establish a Bluetooth pairing connection with the Associated Device.
ENGAGED Mode: is when the Bodyguardian Control Unit is powered ON,
waiting for a command from a paired Associated Device or a request for
pairing from a new Associated Device.
MONITORING Mode: is when the Bodyguardian Control Unit is powered
ON, gathering and storing in the internal memory data at the frequency
specified in the Configuration Settings, and sending the data as requested by
the Associated Device.
STREAMING Mode: is when the Bodyguardian Control Unit is powered ON
and sampling the data as specified in the Configuration Settings, sending them
directly to the Associated Device with periodicity specified by the last
configuration commands received from the Associated Device.
The two main operative modes which characterize the functionalities and intended
use of the device are Monitoring Mode and Streaming Mode.
4.2.1 MONITORING MODE
In monitoring mode the Bodyguardian Control Unit operates as a recorder of the
physiological data. The acquired signals are stored in the internal memory of the
device and works as an Holter. The data are sent from the Bodyguardian Control
Unit to the Associated Device according to the configuration parameters received
from the Associated Device during the configuration settings. The Associated
Device is responsible for forwarding the data to a remote storage server for later
analysis and evaluation.
In Monitoring Mode the Bodyguardian Control Unit can acquire and store the
following data, depending on the configuration received:
Raw Data
o ECG (128 or 256 Hz)
Derived values
o Activity level
o Body position values
o Breathing rate values
o Heart rate values
o Heart rate reliability
o RR interval variability
o Battery level
