1. a Security System
   • a security system is characterized by two basic functions:
     • Redundancy to duplicate critical functionalities in order to minimize serious anomalies;
     • Auto Check for the continuous analysis of the correct functioning of the modules that compose it and the timely reporting of any anomaly that may affect performance.

To meet this specification, the IoT device must be set up for communication through multiple channels to ensure, as far as possible, the correct reporting of an emergency event. The correct functionality of the modules is checked by the firmware with diagnostic procedures launched on a regular basis. The anomalies must be promptly communicated to the user via audio messages, in order to inform him of reduced system functionality (loss of connection, low energy autonomy, etc.).

The sound signal is effective because:

• it always manages to reach the user, unlike the visual one;
• easily implemented with a series of coded sounds;
• timely because it does not require any user action to receive it;
• it does not distract him from sporting activity.

1. b Product Innovation

There are already solutions on the market that perform the posture control function and the measurement of helmet accelerations. All make use of the sportsman’s smartphone as a means of connecting to the telephone network for communication with a data collection server. For the considerations reported in point a), the IoT device must be set up to reach the server via multiple communication channels; for example, it could be equipped with its own GSM module.

By exploiting the potential offered by technology, it is possible to propose an innovative solution and overcome the limits of the devices on the market.

It should also be considered that implementing the emergency signaling functionality alone is not an attractive element for the market. The user hopes that this feature will never be activated. Although the usefulness of the safety system is evident, it could be first neglected in a short time (e.g. the batteries are not recharged regularly), and then abandoned (it is no longer activated).

1. c To overcome this criticality, it is proposed to create a “Virtual Community”.

An example of a Virtual Community was introduced a few years ago by Nintendo with game consoles. Nintendo users who activated the local wireless function could get in touch with other users simply by being in the same action area as the Wi-Fi module. This method allowed to increase player loyalty and the creation of a community between both acquaintances and unknown players.

In this case, the local wireless network allows information to be shared even in the event of an emergency if a GSM connection is not available. The dissemination of distress call messages in the area close to the sportsman allows him to be quickly identified and requested for help.

An element to be developed is the shape of the container of the IoT device and the mode of integration in the helmet. It is not essential to drown the container in the helmet shell. For marketing needs it may be necessary to highlight it also with the possibility of activating light indicators; choice already adopted by some companies.
