Abstract: The invention relates to a head-up display device that includes a retractable combiner having a display position and a storage position; and an actuating mechanism for moving the combiner from its storage position to its display position and vice versa. The mechanism comprises a lifter carriage bearing the combiner. The combiner is arranged standing on the lifter carriage. The lifter carriage executes a motion only in translation in order to reposition the combiner. A shutter element is provided in order to shut the deployment aperture. The shutter element is connected to the actuating mechanism so as to close or open the deployment aperture during at least part of the motion in translation of the lifter carriage.

Abstract: Pressure sensitive transducer assembly that includes a force sensing resistor. The force sensing resistor includes: first and second substrates; at least a first and a second electrically conductive traces on the inner surface of the first substrate including interdigitated fingers defining a sensitive area; and a resistive layer facing the sensitive area. The force sensing resistor includes an auxiliary trace on the inner surface of the first substrate connecting the first trace to the second trace through a constant resistance that is not dependent on the force applied to the substrates. The constant resistance being of a value largely greater than the value of the variable resistance which can be measured indirectly between the fingers when an external force is applied to the substrates. A system and a control method are also proposed.
