Abstract: A spherical enclosure for a camera, has in some examples, an optically transmitting wall, a highly-reflective external surface, a coated internal surface, a collapsible internal lining, and a support tube. The wall may have a region of varying wall thickness providing a lens. The collapsible internal liner is made of a material that obscures the camera's silhouette, and is inserted through an opening in the wall while folded, and then expands into position. The inner surface of the enclosure may be coated with a material that reduces internal reflections. The camera, when mounted in the enclosure has the optical center of the camera coincident with the geometric center of the spherical enclosure, so that distortion of the camera image is minimized.

Abstract: A data storage system wherein a host computer is coupled to a bank of disk drives through a system interface. The interface has a memory with a high address memory section and a low address memory section. A plurality of directors control data transfer between the host computer and the bank of disk drives as such datapasses through the memory. A pair of high address busses electrically is connected to the high address memory and a pair of low address busses is electrically connected to the low address memory. Each one of the directors is electrically connected to one of the pair of high address busses and one of the pair of low address busses.
