Optical systems such as image display systems include a freeform optical waveguide prism and a freeform compensation lens spaced therefrom by a gap of air or index cement. The compensation lens corrects for aberrations which the optical waveguide prism will introduce in light or images from an ambient real-world environment. The optical waveguide prism receives actively projected images at an entry location, and emits the projected images at an exit location after internally reflecting the images along an optical path therein. The image display system may include an image source and coupling optics. The approach permits design of an optical viewing device, for example in optical see-through HMDs, achieving an eyeglass-form appearance and a wide see-through field of view (FOV).

A fuel injection valve for an internal combustion engines is proposed, in which the control of the fuel injection valve member is controlled through the control of the pressure of a control chamber (25). This chamber is either relieved by means of a control valve (31) or is subjected to a high pressure, which brings the fuel injection valve member into the closed position. At the same time as the relief of the control chamber, a valve member (33) of a safety valve (32) that controls the fuel supply to the fuel injection valve is opened so that upon opening of the fuel injection valve, high-pressure fuel simultaneously also can travel by way of a pressure line (12) from a high-pressure fuel reservoir (14) to the injection openings (8) of the fuel injection valve (1). After the end of the injection, the valve member (33) is closed again, together with the closing of the fuel injection valve member (5). Consequently, in the event of a malfunction, unwanted fuel is prevented from reaching injection for a long period of time and consequently possibly destroying the associated engine due to overdosing.
