Fig.2. Data flow schematic.
Fig. 2 shows a schematic of the flow of data from the sensor to the final
product. As can be seen, the information can be downloaded directly to
computer. Once the information is on the computer, then it can go into direct
evaluation, or to a paper hard copy which can then be evaluated. With the
proper hardware, clients can direct-print any log segment from the digital
data stored in the computer.
Clients can elect the method they prefer for data handling. Should they
elect for the data to be supplied on high-density cassette, then this will require
an in-house computer capability based on Novel Network 386 serving on a
33MHz computer or a Compaq System Pro.
Using the computer system, the operator will have many options at his
finger tips. Data will be available on random access. The operator can identify
an area to be viewed and the computer will automatically go to the area.
The computer data can be viewed in a selectable scale and at a selectable
speed. Individual areas can be viewed or the operator can scroll through the
