摘要： A multiple window display system is provided for displaying data from different applications in a multi-tasking environment. The display system includes plural screen buffers (12.sub.l to 12.sub.n) for storing character codes and attribute codes of data which may be displayed on the display screen. Task selection means (26) selectively couples the output of a single selected one of the plural screen buffers to the character generator (16) and attribute logic (18) at any given time. Address modification means (20.sub.l to 20.sub.n, 22.sub.l to 22.sub.n) permits changes to be made in the display windows. The software driver includes screen control blocks (32), window control blocks (34), presentation space control blocks (36), presentation spaces (38), and a screen matrix (40) in system memory. The presentation spaces (38) receive application data for plural windows of the displayable area. Each window defines the whole or a subset of a corresponding presentation space. The screen matrix (40) is mapped to the display screen and filters data from the windows of the presentation spaces to the screen buffer to designate which of the data will be shown in corresponding positions on the display screen.

摘要： A device having two separate sets of contacts and a pivotal axis allowing 360.degree. of rotational freedom between the two sets of contacts. The device is designed to provide the release of radial mechanical energy, stored in a coiled cord due to repeated twisting action, and imparted to the cord from the device attached to the cord. The device provides for continuous electrical connection between the two sets of contacts, by providing unique rotary contacts which allow interruption-free electrical continuity during the full 360.degree. of rotation. The device provides for a minimal degree of friction, to allow for the rapid and thorough release of radial energy, and also provides minimum contact-wear, to allow for optimum electrical continuity and to provide for a long, useful life.
