Patent

CA 2665515

The invention relates to a portable optical signalling device, particularly an item of clothing or a flag or a torch, containing: a signalling component that can be switched between an initial state and a second state, there being a visible difference between the first and second states of the signalling component, one or more sensors for determining the position of the signalling device or its signalling component and/or variables derived therefrom, and a control means linked to the signalling component and the sensor or sensors, such control means being designed to switch the signalling component between its first and second states in response to a change in the position and/or the variables derived therefrom being determined by the sensor or sensors .

L'invention concerne un dispositif portable de signalisation optique, notamment un vêtement ou un drapeau ou une lampe de poche, contenant : un composant de signalisation qui peut être commuté entre un premier état et un second état, lesquels sont distingués par une différence visible, un ou plusieurs capteurs permettant de déterminer la position du dispositif de signalisation ou de son composant de signalisation et/ou des variables dérivées de ce dernier, et un moyen de commande relié au composant de signalisation et au(x) capteur(s), ce moyen de commande étant conçu pour faire commuter le composant de signalisation entre le premier état et le second état en réponse à la détermination par le ou les capteurs d'un changement de position et/ou de variables dérivées.
