Abstract: A screen structure comprising: at least one support element comprising a bistable extendable member; a panel element attached to the at least one support element and comprising a leading edge, wherein the at least one support element and the panel element are configured to be rollable about a first longitudinal axis, to provide for extension and retraction thereof along a direction generally perpendicular to the first longitudinal axis between a first fully extended position and a second position where the at least one support element and the panel element are at least partially retracted; a handle element for extending and retracting the support element and the panel element upon application of a force to the handle element; and characterised by: at least one spacer element configured so that when the at least one support element and the panel element are in the second position, the leading edge of the panel element is substantially parallel with the first longitudinal axis.

Abstract: A screen structure comprises at least one support element comprising a bistable extendable member; a panel element attached to the at least one support element, wherein the at least one support element and the panel element are configured to be rollable about a first longitudinal axis, to provide for extension and retraction thereof along a direction generally perpendicular to the first longitudinal axis; a handle element for extending and retracting the at least one support element and the panel element upon application of a force to the handle element, wherein when the at least one support element and the panel element are substantially fully retracted, the handle element is arrangeable in one or more first positions and in a parked position; and at least one guide element comprising a curved or angled portion which the handle element is configured to bear against and move relative to, to guide the handle element from the one or more first positions to the parked position.

Abstract: A control system is provided for platooning a plurality of vehicles, each of which equipped with vehicle braking control systems and V2V communication system components. The system determines nominal following distances for each of said following vehicles relative to an immediately preceding vehicle, based in part on brake performance capabilities. Vehicle sensors throughout the platoon are implemented to monitor target vehicles positioned relative to the platoon, and some or all of the nominal following distances are dynamically adjusted to account for braking event risks associated with the target vehicles. Adjustment to following distances for trailing vehicles may be proactively applied even before braking reaction is determined or applied for a lead vehicle, and control signals are simultaneously generated implementing vehicle movement adjustments based on the following distance adjustments.
