12. ELECTROMAGNETIC COMPATIBILITY
Essential performance
Chronolife Smart Textile collects and transmits signals without interrupting collection
in the presence of electromagnetic disturbances or motion artifacts. When these dis-
turbances occur, the quality of the signals can be altered to a level evaluated during
electromagnetic compatibility tests. The essential performance of the Chronolife Smart
Textile device is therefore as follows:
• ECG at 200Hz ± 10% on the data available on the server
• Thoracic respiration at 20Hz ± 10% on the data available on the server
• Abdominal respiration at 20Hz ± 10% on the data available on the server
• Axillary temperature at 1 Hz ± 10% on the data available on the server
• Continuous data collection of physiological parameters ± 5% loss over 1 hour
It is necessary to avoid using the device next to other devices or stacked with
the latter, because that may cause malfunctions. If such use is necessary,
the smart shirt and the other devices must be kept under observation in
order to verify normal functioning.
Warning
It is necessary not to use portable RF communication devices (including pe
-
ripherals, such as antenna cables and external antennae) closer than 30cm
to any part of smart shirt, including the cables specified by the manufacturer.
Otherwise, the devices’ performance could be affected.
Warning
In use, the smart shirt receives Bluetooth-type radio-waves at about 2.4GHz. It can the
-
refore suffer interference from other devices using that radio frequency in these band
-
widths. It is therefore recommended to use it away from any devices likely to generate
radio frequencies in these bandwidths.
In use, smart shirt emits Bluetooth waves at about 2.4GHz for a radiated power lower
than 0.2mW.
Frequency range of receiver:
2 400MHz to 2 483.5MHz
Frequency range of transmitter:
2 400MHz to 2 483.5MHz.
Type:
Modulation Bluetooth Low Energy (BLE)
Radiated power equivalent:
<0.02 mW
