  • the switch (S) is attached to a movable body (CM) held to an elastic member which is compressed when the plug (L) is inserted into the buckle (F) and pushes the movable body upward when the plug is deactivated, thus determining the positioning of the switch (S) in the two activation and deactivation modes of the alarm functions controlled by the circuit (1).
  • the circuit-controlled alarm function (1) is automatically activated by inserting the plug (L) into the buckle (F) and automatically deactivates by pulling the plug (L) from the buckle (F) thanks to the effect of the positioning of the switch (S) in two corresponding triggering and disarming functions of the alarm functions controlled by the circuit (1).

  • the temperature sensor (3) is placed, for example, on a plate that also supports the microprocessor (2) and is associated (for example, by gluing) with the buckle body (F).

  • the app checks the MAC address of the module (4) attempting to connect via Bluetooth to the smartphone in use: the Bluetooth connection is established only if the MAC address of the module is in the MAC address list of systems that are authorized to access to the network. Furthermore, it is possible to perform a further check: once the connection is established, the module (4) will send an encrypted verification password together with the packet data; the app will check whether the password is correct or not, and in the case of a negative one, it will interrupt the connection.
  • an authentication check button can be provided: each user can request whether the connection is made with the original device and a written message and / or a audio signal response will confirm whether or not this event is true. It is understood that different procedures for verifying the authenticity of the circuit or app can also be adopted. This procedure also indirectly verifies the origin of the child seat.
  • the microprocessor (2) detects that the harness is closed and if the temperature sensed by the sensor (3) is outside a predetermined range of values (i.e., lower than a first predetermined value or higher than a second predetermined value), the app is activated on the smartphone (5), that is to command the smartphone that generates visual, textual and / or vocal alert signals by alerting the owner of the smartphone.
