Abstract: A method for real-time visualization of a risk zone of a mining vehicle to a person on a mining worksite for augmenting the person's current view of the mining vehicle including capturing with a camera a stream of pictures corresponding at least partly to the person's field of view, recognizing at least one mining vehicle in the picture stream by means of image processing, extracting image data of the mining vehicle from the picture stream, calculating, based on the image data and on preset vehicle risk zone data, at least one risk zone of the mining vehicle adapted to the person's current view of the mining vehicle, and visualizing the risk zone on a person's display such that the person's current view of the mining vehicle is overlayed in real-time with the visualization of the risk zone.

Abstract: A remote identification device (10) for a multirotor (1) comprises an EGNOS enabled GPS receiver (11) for determining a three-dimensional position (P) of the aircraft (1) and a radio transmitter (12) operating at 2.4 GHz for periodically transmitting a data package (D) comprising the determined three-dimensional position (P) of the aircraft (1), a unique identifier (ID) of the aircraft (1), and a timestamp. The transmitted data packages (D) comprise first types (D1) carrying the full information as well as second types (D2) carrying only relative position data. All data packages (D) further comprise ECC data and are cryptographically signed. Remote identification devices (10, 10?) on different aircrafts (1,1?) together with the ground based receiver station (ATC) form a mesh-network by retransmitting foreign data packages. Thus, aircrafts (1,1?) are more easily identified and the data packages can be efficiently used for aircraft registration and law enforcement.

Abstract: A multiband antenna assembly for transmitting or receiving signals in at least two frequency bands is disclosed according to some embodiments. The multiband antenna assembly may include a monopole antenna with a base substrate and a top substrate having defined dimensions and shapes. In some embodiments, the base substrate and the top substrate are arranged with defined distance relative to each other and define a cavity. For example, a first frequency band is basically defined by the present distance. The top substrate may include at least one slot. A second frequency band basically is defined by the design and arrangement of the one slot. The second frequency band may be different from the first frequency band. The cavity may be designed so that the first and the second frequency band comprise preferred monopole sending and/or receiving directions substantially parallel to the extension of the substrates.

Abstract: In a system for supervising the safety on a site with at least one movable object, a drowsiness detection system is arranged at the movable object for supplying data related to a drowsiness state of an operator of the movable object. A monitoring system remote from the movable object receives the drowsiness state related data and logs and/or evaluates this drowsiness state related data.

Abstract: An improved method for avoiding mid-air collision in aviation is disclosed. The method relies on a calibration of radio signal intensities I with radio signal encoded position information L. In other words, after a first reception of a radio signal S advantageously comprising remote aircraft position information L, the radio signal intensity I is measured and a correction factor C is derived. During a next encounter of the radio signal S, a second distance estimation d can be derived using the signal intensity I and the correction factor C. Preferably, relative positioning data is acquired together with the correction factor C and a plurality of correction factors for different relative positions is combined in an at least partly continuous correction function.

Abstract: Digital data acquired from individual cameras and images converted to digitized images are projected onto virtual 3D screens, which can be generated by a computer. This can be realized by way of 3D-accelerated hardware. The images are not, however, projected in 3D. The virtual 3D scenario with the current camera images is projected and presented to the users in 2D. This process makes it possible to use simple cameras (2n) with single lenses. There is no need to use cameras with zoom technology.
