摘要： A near-eye display includes an image generator that generates angularly related beams over a range of angles for forming a virtual image and a waveguide that propagates the angularly related beams over a limited range of angles. An input aperture of the waveguide includes a plurality of controllable components that are selectively operable as diffractive optics for injecting subsets of the angularly related beams into the waveguide. An output aperture of the waveguide includes a plurality of controllable components that selectively operable as diffractive optics for ejecting corresponding subsets of the angularly related beams out of the waveguide toward an eyebox. A controller synchronizes operation of the controllable components of the output aperture with the propagation of different subsets of angularly related beams along the waveguide for ejecting the subsets of angularly related beams out of the waveguide for presenting the virtual image within the eyebox.

摘要： An ocular device includes a housing, a rotatable ring, a first prism fixed in the rotatable ring, an indexable ring and a second prism fixed in the indexable ring. The housing has a stepped inner profile defining first and second circular tracks in the housing, the tracks being concentric about a rotational axis. The rotatable ring is disposed in the first circular track and is freely rotatable about the rotational axis with respect to the housing. The indexable ring is disposed in the second circular track and is indexable about the rotational axis.

摘要： A headset for operably disposing speakers and a visual display on the head of a wearer. The headset includes a beam extending over the vertex of the head for contacting the brow at one end and cooperating with a nape strap on the posterior end for adjusting the fit. Rigid arms extend from the posterior end adjacent the head to terminate in the vicinity of the ears. The arms include compressible compensators to substantially accommodate any size head therein. A visor is pivotally connected to the support beam adjacent the brow piece. The attachment of the visor to the support beam permits the visor to be disposed in a donning position away from the face or an operable position adjacent the face, without requiring a weight bearing surface on the face.

摘要： A method of encoding video signals includes obtaining, averaging, offsetting, and replacing steps. In the obtaining step, a first value comprising a value of a video characteristic for a first portion of a first video signal and a second value comprising a value of the video characteristic for a second portion of a second video signal are obtained. In the averaging step, the first value and the second value are averaged to obtain an average value. In the offsetting step, the average value is offset by a first predetermined offset to obtain a first offset value and the average value is offset by a second predetermined offset to obtain a second offset value. In the replacing step, the first value is replaced with the first offset value on the first signal and the second value is replaced with the second offset value on the second video signal.
