Abstract:
Method and system for confirming continuous remote operation of safety critical devices connected over a fiber optic communication link by establishing the communication link by connecting a safety critical device having a unique ID to a controlling device having a unique ID via the optic link, and sending from each device a data string comprising a separator, a control specific signal, one bit indicating possible remote defect operation indicator, and said unique ID, and receiving and decoding said data string in each connected device, and checking for own unique ID, and checking if said RDI bit is set, and if set indicating to an operator that there are defects in the communication.
Abstract:
A method and apparatus for detection and classification of submerged swimming object from a passive signal generated by the object and an active signal reflected from the object. In an first input of a passive mode branchv a first signal representative of the passive signal is received. A second signal representative of the active signal is received in a second input of an active mode branch. In the active mode branch, the first signal is processed to generate a first classification estimate output, with first clues, of the most probable class of target for the object. In the passive mode branch, the second signal is processed to generate a second classification estimate output, with first clues, of the most probable class of target for the object.The first and second estimate outputs are received in a merger, for generating a merged classification estimate output with clues, whic is input to a joint classifier tha classifies the object by performing joint classification based on said a merged classification estimate output with clues.

The sensor assembly comprises a camera arranged to capture an image of a scene, a plurality of first acoustic transducers adapted to capture an audio input signal from an environment comprising said scene, at least one second acoustic transducer excitable to emit an audio output signal, a support structure arranged to support said camera, said plurality of first acoustic transducers and said at least one second acoustic transducer, said support structure connected to a base, moveably at least about an axis of rotation relative to said base by a support structure positioning actuator controllable from a remote location, and a transmission means adapted to transfer in real-time between said transducer assembly and said remote location a captured image of said scene, a captured audio input signal from said environment, an excitation signal to said second acoustic transducer, and a control signal to said support structure positioning actuator.
Abstract:
Commonly, a transient protection filter circuit is integrated between power sources and the circuits that follow to suppress voltage transients. Pre-existing transient protection filters are implemented such that when a transient is detected, transistors in the path become linear regulators. Instead, this invention uses bridge resistors (R1, R2) to form a voltage divider to dissipate the extra power. The novelty of this invention is that it protects the load not by dissipating the extra power in front of the load as other transient protection filter circuits do, but by providing energy from the transient to the load through a resistor. This implementation solves the problem of thermal runaway that is commonly caused when transient voltages are filtered by dissipating power within r the transistors in the path of the transient and the electric circuits after the transistors.

Abstract:
The invention relates to an optical unit for transforming light, e.g. for improving the coupling of light from a mirror telescope into an optical waveguide, the telescope being adapted to provide an essentially collimated exit beam, wherein the optical unit comprises a rotation symmetric element with a chosen length positioned with its rotation axis in the optical axis and comprising a first and a second conical surface, each with a constant angle relative to the optical axis. The invention also relates to use of the optical unit in telescopes for focusing light into a single mode fiber, including telescopes with a central obstruction in the exit beam, e.g. of the Cassegrain type.

19 ABSTRACT System and method for assisting in docking of a vessel 100. The system comprises at least one sensor 110 which is, for example, a camera located on the vessel 100 and a data processing unit 190 which real-time processes relative 3D 5 position between a first set of distinct points 140 from the dock location and a second set of distinct points 150 from a surrounding area 120. 3D position between distinct surrounding points is basically related to the 3D position of the at least one camera. These are the points that the invention 10 relates the first set of distinct points 140 of the dock location to, and which are used to be able to complete the docking operation even though the points of the dock location are not visible to the at least one camera in the final phase of the docking operation. 15 FIG. 3

Abstract:
A system and method for operating a remotely located safety-critical device, e.g. a weapon station (10, 20). The system comprises a first operating input device (52) to be operated by an operator, providing a first barrier control signal; and a second operating input device (62) to be operated by an operator, providing a second barrier control signal. The barrier control signals are sent through respective secure tunnels through a non-secure communication network (40) to respective activating inputs of first and second barrier circuits at the remote location. The first and second barrier circuits enable operation of the safety-critical device when both are activated. Additional barrier circuits may be included. Video information may be sent from the remote location to the operator station. The video information may be verified as originating from the remote location.
