Abstract: A system including a data storage server, a service provider's server, and a gateway including a transceiver configured to operate at a power level below 5.0 mW, the data storage server generates first tokens, receives a registration from the service provider's server, and issues first tokens to the service provider's server, and receives a first token from the service provider's server. The data storage server receives sensor data from the gateway, the gateway executes the application to receive the sensor data from sensors, and the data storage server issues second tokens to the gateway after receiving the sensor data from the gateway and stores the received sensor data on the data storage or service provider's server.

Abstract: A wearable electronic device includes a wristband; a detachable electronic module adapted to fit into the wristband, the module including a controller, a control button, a tactile sensor, a wireless interface adapter, and a tactile event reproduction element, all connected to the controller. The module is configured to transmit a touch or a tap on the tactile to a second wearable device through the wireless interface adapter, and to receive a notification of a tactile event on the second wearable device through the wireless interface adapter and to reproduce the tactile event using the reproduction element. The tactile sensor can be an accelerometer, a MEMS, a gyroscope, a capacitive sensor or a resistive sensor. The network adapter can be a Bluetooth adapter or ANT+ standard-enabled, and connects to a smartphone or a tablet. The network adapter connects to the second device over the Internet via a server.
