Abstract: Disclosed is a composition comprising at least one interpolymer dispersed within an aqueous medium, the interpolymer comprising at least one unsaturated monomer and at least one selected from the group consisting of at least one conjugated acid, at least one mono-ester of a conjugated acid, and mixtures thereof, and, optionally, at least one surfactant configured to stabilize the interpolymer within the aqueous medium. The conjugated acid may be derived from a naturally-occurring oil, such as tung oil. There is also provided a method for preparing a composition, comprising forming an interpolymer comprising the at least one unsaturated monomer and the at least one selected from the group consisting of at least one conjugated acid, at least one mono-ester of a conjugated acid, and mixtures thereof. There is still further provided a pressure sensitive adhesive comprising the composition prepared according to the disclosed method.

Abstract: A method for constructing a map for a mower includes: acquiring a preliminary map of a work region, two adjacent target points are used as first target points and are connected to form an initial connecting line; selecting a target point farthest from the initial connecting line as a second target point, and using a connecting line between the second target point and the first target points as to-be-processed connecting lines; selecting a third target point for each to-be-processed connecting line; when a condition is met, using connecting lines between the third target point and the target points at the two ends of the to-be-processed connecting line as new to-be-processed connecting lines and returning; retaining each of the third target points whose distance from a corresponding to-be-processed connecting line is greater than the first preset threshold as a map construction target point, and constructing a boundary map.

Abstract: A method for recommending an installation position of a base station, a storage medium, a mower, and a mobile electronic device are provided. The method acquires satellite observation data at a plurality of sampling points along a boundary of a target map; determining target sampling points satisfying a preset condition according to satellite observation data at each sampling point; determining common satellite observation frequency bands according to satellite observation data at the target sampling points; determining the number of the common satellite observation frequency bands at each sampling point according to the common satellite observation frequency bands and the satellite observation data at each sampling point; and determining recommendation information of the installation position of the base station according to the number of the common satellite observation frequency bands at each sampling point.
