SPMHBGW1 RoHS compliance ST modules are RoHS compliant and comply with ECOPACK® norms. 1 Body Gateway device description The Body Gateway (BGW) Devices is a wearable electronic, battery operated device that is worn on the chest for the acquisition, recording and transmission of physiological parameters to external devices which can analyze or forward the data to additional storage elements or system.
SPMHBGW1 2 Body Gateway device architecture 2.1 Hardware: The hardware architecture for the BGW device is shown here below. 2.2 Embedded SW Framework: The embedded SW Frameworks includes a RT OS, board support package, proprietary data aggregation algorithms, embedded memory management system, a BT stack and proprietary data exchange protocol.
SPMHBGW1 3 Embedded SW Framework 3.1 Connectivity: Bluetooth Radio class 2 BT supported profiles: SPP Point to point link to a PC or to any BT enabled device, supporting SPP service, both as a client and as a server Proprietary data exchange protocol on top of SPP designed to optimize power consumption minimizing packets overhead. 3.2 Embedded Data Aggregator 3.2.1 ECG: extraction of · Heart rate · RR peak variability · Heart Rate variability · Electrode detachment alert 3.2.
SPMHBGW1 4 Operating modes: Platform can operate in 4 modes: 6/12 a) Power down mode : BGW device is completely switched off b) Idle mode: the BGW device is visible and connectable to the remote unit through the BT link c) Streaming Mode: is when the Body Gateway is powered ON and sampling the data as specified in the Configuration Settings, sending them directly to the External Device with periodicity specified by the last configuration commands received from the External Device.
