Patent number: 11328461Abstract: Automatic generation of a road map of a site can be performed. Data records collected by vehicles with a GNSS-positioning system while driving are provided, each data record having a position information representing a two-dimensional or three-dimensional position of the vehicle, an identification reference specific to a corresponding vehicle, a time tag, and a heading information. The data records are assigned to corresponding trips based on the time tag and the identification reference. The trips are mapped within an area and the area is divided into a plurality of uniform tiles. For each tile, a heading information variance of the data records covered by the respective tile is determined. A tile is defined as junction tile, if the tile has a heading information variance higher than a computed threshold variance. An area of interest (AoI) having a perimeter is determined by which a plurality of junction tiles is surrounded.Type: GrantFiled: April 9, 2020Date of Patent: May 10, 2022Assignee: SAFEMINE AGInventors: Fabian Ismael Furger, Johannes Huber

Patent number: 10096894Abstract: 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.Type: GrantFiled: December 22, 2016Date of Patent: October 9, 2018Assignee: SAFEMINE AGInventors: Thomas Kaufmann, Urban Mäder

Patent number: 8994557Abstract: A collision warning apparatus, to be mounted to a vehicle, has a roof mount unit (40), to be fixed to the vehicle's roof, as well as a cabin mount unit (41) to be located in the driver's cabin. A digital transmission line (42) is provided for connecting the two. The roof mount unit (40) houses the antennas as well as the analog circuitry of the apparatus, while the cabin mount unit (41) comprises a display (26). The data sent through the transmission line (42) is digital, which allows to make the transmission line thin and flexible. The roof mount unit (40) has a magnet (43) and batteries (48) mounted in its base section (46), with the lighter components, in particular the antennas (30a, 31a, 32a) located in its head section (47).Type: GrantFiled: December 11, 2009Date of Patent: March 31, 2015Assignee: Safemine AGInventors: Peter A.
