Abrégé

The invention relates to a device for securely attaching a boot onto a first ski, which includes a member for attaching the boot onto the first ski, and a control circuit. The boot includes an attachment member configured such as to make it easier to detach the boot and the first ski from one another upon receiving a detachment signal. The boot includes a control circuit configured such as to: determine an angular spacing between a first direction of the first boot and a second direction of a second boot; determine the forward movement of the first and second boot along the longitudinal axis of each of said boots; calculating at least one parameter from the angular difference and the forward movements of the first and second boot; comparing the parameter to a threshold parameter; and transmit the detachment signal on the basis of the comparison.

The device for securely attaching a shoe to a first ski comprises an attachment member for attaching the shoe to the first ski and a control circuit. The attachment member is configured to assist the disengagement of the shoe from the first ski on receipt of a disengagement signal. A control circuit is configured to: · determine an angular offset between a first direction of the first ski and a second direction of a second ski, •determine the forward progression of the first and second skis along the longitudinal axis of each of said skis, •calculating at least one parameter from the angular offset and the forward progressions of the first and second skis, comparing the parameter with a threshold parameter, and transmitting the disengagement signal on the basis of the comparison.

Abrégé

The invention relates to an emitter (1) that emits a wavelength in the visible and/or infrared spectrum in order to illuminate a scene. An observation system (3) is configured to output an image representative of the illuminated scene to an observer (4). The emitter (1) is configured to generate a light emission (2) by means of at least one flash having a lighting power that exceeds the threshold at which a glare occurs. The observation system (3) has a first operating condition and a second operating condition for the scene observed by the observer (4), the second operating condition transmitting less lighting power than the first operating condition. A synchronization circuit (5) is configured to synchronize the emitter (1) and the display system (3) such that the observer (4) does not experience a glare during the emission stage of the emitter (1).
