Patent GB-2227389-A (GB)
Title: Air traffic controller
Inventor: WHICHER PETER GEORGE
IPC: G08G5/00
Filed: 1989-12-07
Abstract: In an automatic air traffic management system aircraft fly in "tubes" each having a line 11 representing the normal assigned path of the aircraft, an inner boundary around a normal zone 13 representing acceptable deviations of the aircraft from the line 11, and an outer boundary around a warning zone 15. The system monitors the position of each aircraft and issues a warning to an air traffic controller if an aircraft leaves the normal zone 13 of its allotted tube, and a more urgent warning if it leaves the warning zone 15. This substantially relieves the air traffic controller of the need to monitor the aircraft to ensure that they remain within the tube, permitting the air traffic controller more time to devote to guiding aircraft into and out of tubes and through tube junctions, to maintaining correct spacing between aircraft along the tube, and to providing course correction instructions when aircraft arrive at bends in the tube. <IMAGE>

Title: Sequence controller with combinatorial Boolean logic
Inventor: SCHULTZ MICHAEL E
IPC: G05B19/05
Filed: 1992-06-02
Abstract: A programmable controller for sending the status of input devices and controlling the state of operating devices in accordance with a stored ladder logic control program includes a state machine instruction. A processor module (20) (Figure 2) has a memory (36) for storing data regarding each state of an apparatus being controlled. This data defines the status of apparatus operating devices for each state, and the legitimate transitions from that state to other selected states, along with a Boolean logic expression of selected input conditions which determines when a state transition should occur. A processor responds to the state machine instruction by examining the truth of the Boolean logic expressions for the present state of the apparatus to detect if a state transition should occur. Upon such a detection, the controller advances to the state associated with the detected true expression. State transitions also can be defined as occurring upon a specified change in the status of a single input. A ladder logic processor (39) is supported by a microprocessor (41) for the more complex operations. Other mechanisms are provided to detect illegitimate states of the apparatus and take appropriate action. <IMAGE>
