Patent number: 8755950Abstract: A termination system that transmits on a cyclic basis, from a control station to an unmanned vehicle, pairs of mutually dependent code and counter values whose dependency is determined by a termination algorithm. The vehicle has knowledge of the algorithm and can hence validate a received code/counter pair using the same algorithm. If the received code/counter pair is invalid, the vehicle can decide to self-terminate. The control station includes a termination actuator that allows the vehicle to be remotely terminated by invalidating, when actuated by an operator, the code/counter pairs that are transmitted to the vehicle.Type: GrantFiled: August 6, 2009Date of Patent: June 17, 2014Assignee: Saab ABInventor: Rikard Johansson

Patent number: 8365058Abstract: A method of detecting communications errors by coding messages as pictures. A communications method useable to safely communicate a message or a signal from a first safety approved entity to a second safety approved entity via a third, non-safety approved entity including that each command is sent with the aid of a command message from the first to the second entity, an acknowledge message from the second to the first entity, and a go-ahead message from the first to the second entity.Type: GrantFiled: March 27, 2007Date of Patent: January 29, 2013Assignee: SAAB ABInventors: Rikard Johansson, Jan-Erik Eriksson, Peter Stendahl

Patent number: 8194533Abstract: A data bus node, being a control node or a sensor node and being arranged to communicate over a TDMA data bus. The node includes a time signal processing device being configured to define a TDMA time slot transmission schedule for at least the node. A switch is configured to either connect or isolate a transmission path of the node to the bus and is configured to be controlled by the TDMA time slot transmission schedule for the node via a bus transmission access control device. The bus transmission access control device is configured to be further controlled by at least one external control signal via at least one external data transmission link being physically separated from the bus. A fault tolerant data bus system includes such a bus node and an aircraft exploiting the node/system. The babbling idiot problem is solved and at the same time the node/s/system fail silent behavior is enhanced.Type: GrantFiled: May 16, 2007Date of Patent: June 5, 2012Assignee: SAAB ABInventors: Rikard Johansson, Kjell Wistedt

Patent number: 7840832Abstract: A fault tolerant data processing system for controlling a real time process. The system is tolerant to systematic faults in its software. The system includes a data processor unit with a program memory and a data memory and input and output units where program software residing in the program memory can be executed on the data processor unit. The system includes a normal-mode software program residing in the program memory, and a backup-mode software program also residing in the program memory arranged to perform the same or similar function of the normal mode software program but being differently implemented than the normal-mode software program, and where a trigger signal received by the data processor unit can switch execution control such that the normal-mode software program stops executing and the backup-mode software program starts executing.Type: GrantFiled: May 16, 2007Date of Patent: November 23, 2010Assignee: SAAB ABInventors: Rikard Johansson, Kjell Wistedt

Patent number: 7809496Abstract: A system for monitoring a traffic management system, such as an Air Traffic Management (ATM) system, which includes a position retrieval station, operable to retrieve position information for a traffic object, e.g. a radar station devised to collect radar echoes and generate radar image signals. A computer system is connected to the position retrieval station for generating radar trace data from received position information. An operator station is connected to the computer system for processing trace data for presentation. A false position information source is connected to provide artificial information corresponding to a predetermined property of a false traffic object to the computer system. A comparator unit is connected to the operator station for receiving trace data generated from the artificial information, and devised to detect correlation between the generated trace data and the predetermined property of the false traffic object.Type: GrantFiled: November 2, 2006Date of Patent: October 5, 2010Assignee: SAAB ABInventor: Rikard Johansson
