### e-Health Platforms
PlaIMoS uses identical accelerometer technology and a specific algorithm to detect falls. The characteristics of general-purpose health platforms are based on studies of architectures and communication technologies for wearable health-monitoring systems [23]. These characteristics include:  
1. Health sensors: the types of measurements the platform can perform using a wearable device. 2. Communication system: the communication architecture that transmits data from the wearable device to the collector system. 3. Data security: the security mechanism used to protect the information generated on the platform. 4. Emergency detection: the capacity to launch a push notification if an emergency event occurs. 5. Display devices: the type of devices that display data generated by the platform. The main features of the various platforms are summarized in Table 1. \begin{table}
