Abstract: A head-mounted device may have left-eye and right-eye optical modules, each of which includes a lens barrel/support, a gaze tracker in the lens barrel, a display coupled to the lens barrel, and a plurality of lenses in the lens barrel that provide an image from the display to a corresponding eye box. The gaze tracker may include light emitters mounted on a printed circuit and light detectors. Each of the lenses may include a peripheral edge that defines a footprint that entirely overlaps a footprint of the printed circuit. The display may be mounted in a display bezel, and the display bezel may include recesses in which the light emitters are mounted. The recesses may be chamfered to increase the signal-to-noise ratio (SNR) of the gaze tracker. Alternatively or additionally, a lens and/or a reflector may overlap the light emitters to increase the SNR of the gaze tracker.

Abstract: An injury protection accessory for a riding vehicle (e.g., motorcycle), the accessory comprising: at least one shield (4), disposed at the side(s) of the riding vehicle, the shield comprising: a substantially vertical hinge (12), attached to the body or the chassis of the riding vehicle; and one or more substantially horizontal bars (10), attached to the hinge; the shield having an open state, in which one edge of the shield is separated from the body of the vehicle, thereby allowing the rider thereof to get off the vehicle, and a closed state, in which both sides of the shield are engaged with the body of the vehicle, thereby protecting the rider from injury.
