Integrated Sequence Display Device 
.
The problem: 
To provide a means for integrating a planned test 
sequence with real-time changes indicated on a visual 
display which includes a record of both planned and 
unplanned events related to a time base. 
The solution: 
A device that incorporates a display for scheduled 
information coupled with a means to include real-time 
changes. The unit features a scroll-like paper chart 
that is motor driven and can be advanced or reversed 
as necessary to display the time span of interest. 
How it's done: 
The basic device is a mechanical strip chart recorder 
involving a display chart, rollers, drive motors with 
associated gears and clutches, and a real-time record-
ing area. The planned events are laid out in sequence 
on a continuous roll of paper which is attached to the 
motor driven rollers. On the left side of the chart, a 
scale represents the starting and terminating times of 
a given operation. These time increments are arranged 
in descending order from top to bottom so a forward, 
or bottom-to-top rotation will bring the chart closer to 
event termination time. The center portion shows all of 
the individual occurrences and • their nomenclature, 
manpower assignments, start and completion times, 
and associated data. Changes from the planned
schedule are recorded in the time frame of their actual 
occurrence and indicated by a special format stamp; 
and cross reference is made between the scheduled 
event block and its new location to provide immediate 
recognition. 
The far right chart area is used for notation of 
significant events which occur for individual time 
frames. This area also contains pre-noted listings and 
notes that are the result of observation of displayed 
occurrences. Flags are added to call attention to 
events of particular significance. Lines, both diagonal 
and horizontal, may be added to note event times, 
completions, or changes of particular interest to the 
user.
