Patent CA-1288873-C (CA)
Inventor: BEARD MARIAN H
IPC: G06F3/06
Filed: 1987-04-09
Granted: 1991-09-10
Abstract: ABSTRACT OF THE DISCLOSURE          A multiprocessor system comprises concurrent display of video data reflecting the operation of two processors in discrete portions of a single display screen with a user interface adapted for interaction with both processors. One processor controls the entire display while allocating a portion of the display screen for the use of the other processor which processor emulates a target processor system, for example, the IBM PC. To fully emulate another target processor system requires emulation of its screen facility and abstractions used in the display operations of the targeted system. The one processor is a general purpose host computer system having a central processor with real resources including I/O devices, main memory, a video display for displaying information on the display screen of the display and user input means, e.g. a keyboard and a mouse, to the host computer to provide input to the display screen. Also included in the system is at least one emulating computer having a processor emulating the target processor unit with interface means for emulating the previously identified real resources for the emulating processor including means in the host system responsive to the input/output of the emulating processor for sharing of the central processor real resources by the emulating processor. A user interface is represented on the display screen in the form of metaphoric objects, called icons, with which the user can interact by changing the input focus to a designated object by visually pointed to it via the input means, which thereafter permits manipulation of the designated object or interaction with data input/output relative to the designated object. This input means is also used to initially change the input focus to either the allocated emulating processor screen portion or to the remaining portion of the central processor display screen prior to interaction with the metaphoric objects in a selected screen portion, the change of the input focus causing subsequent user input via the input means to be directed to the selected screen portion until interrupted by a change in focus input to the other of the screen portions by the user via the input means. An icon may be a representation of virtual object, such as a virtual floppy disk, that is accessible in either the host system world or in the emulating processor world even though the virtual floppy disk may have a filing system alien to the host system world. Facilities are also provided to permit transferring of displayed data reflecting the operation of one processor to the control of the other processor in response to user inputs selecting the data to be transferred and indicating the destination of the selected data on the display. More specifically, if data from each processor is displayed in a discrete portion of the display screen, the user may select data in one processor's controlled screen portion and transfer it to the other processor's controlled screen region, and vice versa.

Title: Spring coil and spring assembly
Inventor: FLESHER KEITH A
IPC: A47C23/043
Filed: 1987-05-14
Granted: 1991-10-08
Abstract: ABSTRACT OF THE DISCLOSURE    A spring coil has an open-ended terminal convolution which is connected to the body of the coil through a gradient arm.  The gradient arm can be readily varied in length in manufacture to alter the compression and thereby the firmness of the spring coil.  One or more offset portions can further be provided on the terminal convolution.  Such offset portions are advantageously formed with a major straight part which is outwardly spaced from minor straight parts.  This provides a three point engagement for the offset portion when connected to a border wire with a border wire helical spring. The springs making up an innerspring assembly are arranged in rows and columns.  The offset portions of adjacent springs are overlapped in rows and are joined together with cross-helical springs that extend along columns and encircle the overlapped portions.  The offset por-tions of the spring coils have inside and outside shoulders adjacent their ends, and the pitch of the cross-helicals is advantageously chosen so that a cross-helical simultaneously engages the outside shoulders of one of a pair of overlapped offset portions to hold the spring coil against rotation.  The cross-helical prefer-ably also catches the inside shoulders of the other overlapped portion to additionally hold that spring coil against rotation.  A mattress innerspring is further disclosed with the rows arranged across the width of the mattress and the columns extending along its length. Cross- helicals can also be used across the width of the mattress in addition to those extending along the longitudinal columns. The width cross-helicals can be used for extra firmness for the entire mattress, or for selected areas, such as the middle third.  One embodiment further shows the use of such orthogonal cross-helicals with overlapping spring coil rows.
