A preparatory sequence for determining the aerodynamic drag surface and/or the rolling coefficient of a vehicle in real conditions of movement, without braking, on a road having a point of departure and a point of arrival, comprises: Five methods may be used for determining the aerodynamic drag surface and/or the rolling coefficient.

Method for determining the aerodynamic drag surface and/or the rolling coefficient of a vehicle, and associated measuring device

The invention relates to a front-side imager comprising in succession: —a semiconductor carrier substrate, a first electrically insulating separating layer, and a single-crystal semiconductor layer, called the active layer, comprising a matrix array of photodiodes, wherein the imager further comprises between the carrier substrate and the first electrically insulating layer: —a second electrically insulating separating layer, and —a second semiconductor or electrically conductive layer, called the intermediate layer, arranged between the second separating layer and the first separating layer, the second separating layer being thicker than the first separating layer.
