  • Publication number: 20240151546
    Abstract: A method of generating an indication of where, within a geographical region, a mobile unit can move to from a specified origin in the geographical region using a network of navigable elements in the geographical region and in accordance with a total movement budget specified for the mobile unit, the method including: for each sub-region of a set of one or more sub-regions of the geographical region, associating one or more corresponding utilization amounts with said sub-region; identifying an initial navigable element that corresponds to the origin; performing a sequence of steps, wherein each step includes: using an identification function to try to identify an additional navigable element, wherein the additional navigable element is a neighbour of an already-identified navigable element and can be reached by the mobile unit from the origin in accordance with the total movement budget; and in response to the identification function identifying an additional navigable element of at least one sub-region, perfo

  • Patent number: 11339137
    Abstract: The present invention relates to a novel, one-stage method for preparing and isolating 3,4-dichloro-N-(2-cyanophenyl)-5-isothiazolecarboxamide (isotianil), which has microbicidal and plant-fortifying (host defence inducer) properties. In the method according to the invention, the amount of waste from the production process (e.g. solvent) is significantly reduced. The product is provided in high yield and purity (minimal amount of by-products and impurities). Compared to existing preparation methods, the method according to the invention has the advantage of low corrosiveness and high yield and high selectivity.
