Abstract: A method for switching a base station, a mower and a multi-base station working system are provided. The method includes: obtaining, when the number of first common-view satellites between the mower and a first base station is less than a first threshold, the number of second common-view satellites between the mower and a second base station; when the number of the first common-view satellites is less than a second threshold and the number of the second common-view satellites is greater than the second threshold, obtaining the first trajectory of the mower based on the first base station and the second trajectory of the mower based on the second base station; determining, based on the first and second trajectories, a coordinate transformation matrix; and switching from the first base station to the second base station based on the coordinate transformation matrix, the second threshold being less than the first threshold.

Abstract: A movement control method, an electronic device, and a computer storage medium are provided. The method includes: acquiring a first polygonal grid map corresponding to a target work region, determining an avoidance subregion non-traversable for the autonomous mobile mowing apparatus in the target work region according to three-dimensional information of each of polygonal planes in a first polygonal grid map and parameters of an autonomous mobile mowing apparatus; deleting a polygonal plane corresponding to the avoidance subregion from the first polygonal grid map to obtain a second polygonal grid map; and controlling the autonomous mobile mowing apparatus to move according to a second polygonal grid map. Based on the method, the region non-traversable for the autonomous mobile mowing apparatus can be avoided, thereby avoiding a danger caused by an abnormal handling behavior triggered by the autonomous mobile mowing apparatus, and improving safety of movement of the autonomous mobile mowing apparatus.

Abstract: An apparatus comprises a power source connected to a buffer capacitor. The apparatus comprises a first switch connected between the buffer capacitor and a driven switch. The buffer capacitor is charged by the power source when the first switch is turned off. The apparatus comprises a comparator. The comparator monitors the charging of the buffer capacitor. In response to the buffer capacitor reaching a threshold amount of charge, the comparator turns on the first switch to initiate a charge redistribution of charge from the buffer capacitor to the driven switch.

Abstract: A method for path planning for an automatic gardening device, the method including:
receiving a preset travel direction in a work region;
dividing the work region into a plurality of subregions;
determining, for each of the subregions, an actual planned direction in the subregion from the preset travel direction and a recommended planned direction in the subregion, and determining a local planned path corresponding to the subregion based on the actual planned direction, where a path of traversing the subregion along the recommended planned direction has a shortest length, or a travel duration of traversing the subregion along the recommended planned direction is shortest;
acquiring a moving sequence between the subregions;
determining a global planned path of the work region based on the local planned path of each of the subregions and the moving sequence between the subregions.

Abstract: An apparatus such as a power supply or other suitable entity includes a controller. The controller receives a target ripple current value indicative of a ripple current associated with an output voltage and corresponding output current of a power converter powering a load. The controller selects a switching frequency of operating the power converter as a function of a magnitude of the received target ripple current value. The controller applies the selected switching frequency to switches in the power converter to produce the output current with a magnitude of the ripple current as indicated by the target ripple current value.
