Sphere is a multi-user, multi-touch-sensitive spherical display in which an infrared camera used for touch sensing shares the same optical path with the projector used for the display. This novel configuration permits: (1) the enclosure of both the projection and the sensing mechanism in the base of the device, and (2) easy 360-degree access for ...

Covering a sphere with spheres
Mathematika, 1963We work throughout in n-dimensional Euclidean space. It has been clear, since the publication of [1], that it should be possible to obtain quite good upper bounds for the number of spherical caps of chord 2 required to cover the surface of a sphere of radius R > 1, and for the number of spheres of radius 1 required to cover a sphere of radius R > 1 ...

Stress control for sphere-sphere and sphere-plane electrode configurations
Proceedings of the Institution of Electrical Engineers, 1968The highest potential gradient between a sphere and plane has been calculated by the method of images for various gap-length/sphere-diameter ratios. It is shown that, if the distance between the plane and the most distant point on the sphere is fixed at S, while the sphere diameter is allowed to vary, the highest stress on the sphere surface has the ...
