This facility for packing the radar reflector up has been achieved in that its reflecting main surfaces have each been divided up by means of specially aligned buckled folds into a plurality of parts which can be folded in towards one another when the reflector is to be folded up. | 10-30-2008 |
| 20080255730 | Safety arrangement for a discharging signalling system - A method and system for allowing unsafe action signals in a dispensing system of a vehicle. A discharging signalling system of at least one dispenser of a vehicle includes an activation circuit arranged to discharge the dispenser. An indicator is arranged to indicate that dispensing is allowed. The activation circuit includes a first safety arrangement arranged to be activated when an indication from the indicator indicates that dispensing is allowed. The activation circuit also includes a second safety arrangement arranged to be activated when a discharge of the dispenser is indicated. | 10-16-2008 |
| 20080252758 | Image capturing device - An image capturing device including an optical unit arranged to receive an image of a scene and to convey the scene image to an area outside the image capturing device designed for the eye or eyes of a user looking into the image capturing device, a first image capturing unit arranged to capture eye movements so as to register the directions or movement of the eye or eyes of a person seeking through the scene, and a second image capturing unit arranged to capture the image of the scene. | 10-16-2008 |
| 20080249669 | Device at an airborne vehicle and a method for collision avoidance - A device at an airborne vehicle including a flight control system configured to control the behaviour of the airborne vehicle based on acceleration commands, a first control unit configured to provide the acceleration commands to the flight control system, and a collision avoidance unit. The collision avoidance unit includes a detection unit arranged to detect whether the airborne vehicle is on a collision course and a second control unit arranged to feed forced acceleration commands to the flight control system upon detection that the airborne vehicle is on a collision course. A method for collision avoidance in an airborne vehicle. | 10-09-2008 |
| 20080224410 | Target mechanism and a base unit in such a target mechanism - A target mechanism for shooting, including a base unit and a target body which is movably connected to the base unit. The base unit includes elements for moving the target body from a first position to a second position. The second position is an optional position based on at least a signal to the moving elements. A base unit in a target mechanism including elements for moving a target body from a first position to a second position. The base unit includes a control unit arranged to generate at least a signal to the elements for moving the target body to the second position based on the at least a signal. | 09-18-2008 |
| 20080222577 | Method for designing array antennas - A method for designing low signature array antennas using a calculation method. The method proposes a way of improving antenna and signature performance of array antennas. According to the method electromagnetic antenna and signature characteristics are specified, an iterative optimizing method is performed to design the antenna to fulfil the specified characteristics, the iterative method is interrupted when a design fulfils the specified characteristics, and the specified characteristics are readjusted in an iterative optimizing method to follow if the specified characteristics not are fulfilled. | 09-11-2008 |
| 20080215191 | Vehicle control system and method using control allocation and phase compensation - A vehicle control system and method combining control allocation and phase compensation for forming a phase compensated actuator command signal based on a control demand signal. A feedback unit includes a matrix multiplication unit for forming an estimated behaviour signal, from a control efficiency matrix and the actuator command signal. The estimated behaviour signal is fed to a second summation unit for forming a difference signal. The difference signal from the summation unit is processed by a filter unit for forming a feedback signal which is connected to a first summation unit for forming a modified control demand signal, such that the modified control demand signal is adjusted to always represent a control demand realisable by the vehicle. The modified control demand signal of the first summation unit is further connected to the second summation unit and to a control allocator which output is then connected to the matrix multiplier to form a feedback loop. | 09-04-2008 |
