The evolution of frictional strength has great fundamental and practical importance. Applications range from earthquake dynamics to hard-drive read/write cycles. Frictional strength is governed by the resistance to shear of the large ensemble of discrete contacts that forms the interface that separates two sliding bodies. An interface's overall strength is(More)
The color gamut of RGB primaries displays can be increased by using more saturated primaries, with the penalty of a corresponding significant decrease in brightness. We present a multiple primaries technology that enables substantial increase in both the color gamut and brightness of projection displays and describes results of prototype projection systems(More)
