Abstract

A sensor based computer arrangement is shown which allows a computer 10 to operate in either a Control Mode so that it responds to program commands from a host computer 11, or in an Interactive Mode, so it acts as a data transfer medium between a user's terminal 12 and the host 11.

Distributed Sensor Based Computing System

A sensor based computer arrangement is shown which allows a computer 10 to operate in either a Control Mode so that it responds to program commands from a host computer 11, or in an Interactive Mode, so it acts as a data transfer medium between a user's terminal 12 and the host 11.

Specifically, a controlled apparatus 13 and the terminal 12 are connected to the sensor based CPU 10, which will hereafter be referred to as the "controller". The controller 10 communicates with the host interactive terminal system 11 over an appropriate conventional teleprocessing link.

A program 14 in the controller 10 controls the data flow to and from the terminal 12 and between the controller and host 11. This program has two modes of operation. In the first, the Interactive Mode, data is simply passed between the terminal 12 and the host 11. In this mode, the user interacts with the host exactly as if he were directly connected thereto and he is completely unaware of the existence of the controller 11.

The second mode of operation is the Control Mode. Control Mode is invoked by the reception of a predefined special sequence of characters from the host 11. This can be any convention the user wishes to adopt, but would usually be a pair of characters not occurring together in the normal interactive operation, such as a "carrier return" immediately followed by a "backspace". Upon detection of the control sequence the control program 14 enters Control Mode, logically switches the terminal 12 out of the loop, and all subsequent communication is between controller 10 an...
