Abstract:
The present invention relates to a target tracking system comprising tracking means arranged to perform model-based tracking of a target based on received measure- ments from a sensor. The target tracking system is characterized in that it further comprises: detection means arranged to detect as a target performs a manoeuvre; and output switching means arranged to switch from a first output mode in which model estimations of said tracking means are forwarded, to at least a second output mode in which only reliable outputs are forwarded, in response to information indi- eating the detection of a target manoeuvre being received from said detection means. The present invention also relates to a collision avoidance system, a method for tracking a target and a computer program product.
Abstract:
The invention relates to a device (10; 110) for collecting oil spillage in the sea, comprising a collecting member (30; 130), weight means (40; 140) for bringing or keeping the collecting member (30; 130) under the surface of the water, wherein the collecting member (30; 130) has a net-like configuration with a plurality of openings or passageways configured to let water through and prevent oil from passing through. The invention also relates to a method for collecting oil spillage in the water.
Abstract:
It is an object of the present invention to provide a termination system allowing an unmanned vehicle to be remotely terminated in a safe and cost efficient manner. The object is achieved by a termination system (1; 1A; 1 B) based on the principle to transmit on a cyclic basis, from a control station (3) to an unmanned vehicle (5), pairs of mutually dependent code and counter values whose dependency is determined by a termination algorithm (27A). The vehicle (5) has knowledge of the algorithm (27A) and can hence validate a received code/counter pair using the same algorithm (27B). If the received code/counter pair is invalid, the vehicle can decide to self-terminate. The control station comprises a termination actuator (13) that allows the vehicle (5) to be remotely terminated by invalidating, when actuated by an operator, the code/counter pairs that are transmitted to the vehicle.
Abstract:
The present invention provides an improved method for positioning of an object. The method comprises the steps of: - sweeping at least two line-shaped light beams having different inclination angles across an object comprising at least three non-aligned light- reflecting areas at known positions relative to each other; - determining the bearings of said light beams when reflected by said light- reflecting areas; and - calculate the three dimensional position and/or tilt of said object relative to said light source based on said determined bearings and the known relative positions of the light-reflecting areas. By using two light beams having different inclination angles, two light-beam bearings are obtained for each light-reflecting area, which bearings can be used to calculate the three dimensional position and/or tilt of the object relative to the light source. According to an aspect of the invention, the proposed positioning method is used in a vehicle wheel alignment application wherein it allows for simultaneous wheel toe and camber-angle determination.

Abstract:
The present invention refers to a reflector comprising a reflector dish 2 and a backing structure 5, wherein the reflector dish 2 has a reflecting surface 3 and a back surface 4, and wherein the backing structure 5 is arranged in a pattern on the back surface 4 of the reflector dish 2 for supporting and stiffening the reflector dish 2, wherein the backing structure 5 comprises a first backing structure skin 6 and a second backing structure skin 7 and a backing structure core 8 there between, wherein the core 8 is substantially thicker than each skin 6, 7 and the backing structure 5 is arranged such that the first backing structure skin 6 is faced against the back surface 4 of the reflector dish 2. The present invention also refers to a method of manufacturing a reflector.
Abstract:
The present invention relates to a device for simulating fire effects in military or civilian combat training, said device comprising a light source (1 ) and means adapted to control a light lobe formed by light beams from said light source. Said means comprises a two-dimensional array (3) of elements (18) electronically controllable to assume a selected state among at least a first state of letting through said light inciding thereupon in a main direction of said light lobe or a second state of not letting through said light inciding thereupon in said main direction, and a unit (2) adapted to control said elements for designing the spatial propagation of said light lobe.
Abstract:
This invention concerns a fire simulation method and system for simulating ammunition from a weapon. The method comprises the steps of: - determining a trajectory of the simulated ammunition, - emitting a light beam along a simulation axis, and - coding said light beam with information. The method is characterized by the following steps - determining a point in time when the simulated ammunition passes a target, - determining a value related to the distance between the simulation axis and a momentary position of the simulated ammunition along the trajectory at that point in time and - emitting the light beam coded with the determined value during a predetermined time period.
Abstract:
The invention concerns a jamming device (2) on an object for jamming a target seeker arranged to generate an image of its surroundings and extract targets from the image. The device is characterized in that it comprises a laser (4) arranged to emit laser radiation at the target seeker so that the laser radiation is projected on the image, plus means (5, 7) disposed in connection to the laser and arranged to modulate the intensity pattern of the laser radiation with the intent of manipulating the image in order to make it more difficult for the target seeker to extract the object as a target. The invention also describes a jamming method.
