Abstract: A perception device including a receiver configured to receive sensor information including information about a location of one or more objects detected by a sensor; a memory configured to store an occupancy grid of a predetermined region, wherein the occupancy grid includes a plurality of grid cells, wherein each grid cell represents an area in the predetermined region, wherein at least one grid cell of the plurality of grid cells is associated with a respective single occupancy hypothesis; a single occupancy hypothesis determiner configured to determine a single occupancy hypothesis; wherein the single occupancy hypothesis includes degree of belief of occupancy of the grid cell depending on the sensor information; wherein a contribution of a sensor information value to the degree of belief of occupancy substantially decreases with an increase of a distance of the location of the object detected by the sensor from a center of the grid cell.

Abstract: Colorless formulations of optical brighteners from the 4,4'-bis-triazinylamino-stilbene-disulfonic acid series, which are obtained by heating the brightener together with an oxyalkylate.

Abstract: Process for the transformation of comminuted and modified cellulose ether swellable with water, into a material that may easily be further processed and may thus be used without difficulty in particular in the production of hygienic pads, napkins, bandages, tampons, wrapping papers, insulating material, household papers and similar articles. In said process the modified cellulose ether is attached by electrostatic flocking to at least one surface of a web-shaped hydrophilic support that has been wetted with water and the support is dried.

Abstract: Process for the preparation of 1,4-naphthodinitrile, by reacting o-phenylene-diacetonitrile with a glyoxalbisaldimine. By this process the 1,4-naphthodinitrile is easily obtained in a one-step process. This compound is an important intermediate for the production of 1,4-naphthalene-dicarboxylic acid.

Abstract: Inorganic per-compounds-containing oxidizing, bleaching and washing compositions having a content of acylated oxamides as activators for the inorganic per-compounds. Said activators permit better utilization of the active oxygen while securing good stability to storage.
