Abstract: A theft prevention system includes a robotic garden tool that includes a housing, and a set of wheels coupled to the housing and configured to rotate to propel the robotic garden tool on an operating surface. The robotic garden tool further includes at least one wheel motor coupled to one or more wheels of the set of wheels to drive rotation of the one or more wheels. The robotic garden tool further include a first electronic processor configured to detect a potential theft event associated with the robotic garden tool. The first electronic processor may be further configured to engage in an anti-theft action in response to detecting the potential theft event. The anti-theft action may include ceasing at least one operation of the robotic garden tool until the first electronic processor receives a code indicating that the potential theft event should be ignored.

Abstract: A battery pack may include a housing, defining an internal space of the battery pack. A battery pack may include a cell assembly, located in the internal space and comprising multiple cells. A battery pack may include a circuit board, located in the internal space and disposed at one side of the cell assembly. A battery pack may include a heat management apparatus, the heat management apparatus comprising: one or more first thermal isolation plate, disposed between the cell assembly and the circuit board, and used for reducing the transmission of heat between the cell assembly and the circuit board; and one or more thermally conductive plate, configured to at least partially transmit heat generated by the cell assembly in the internal space to the outside.

Abstract: The present invention provides a retaining component, a battery assembly and an end structure. The retaining component of the present invention is configured to fix multiple cells at the top and/or bottom of the multiple cells, and a hole open to the outside is provided in the retaining component at a position corresponding to a fusible part, so that the fusible part is exposed. According to the present invention, the fusible part can be exposed to the outside at the opening; this provides space for melt-through of the fusible part. For example, when melt-through occurs due to current flow through the fusible part of a collector component, the structure of the opening allows the fusible part to melt through fully, thereby protecting the circuit.

Abstract: A robotic garden tool for use with a boundary wire producing an electromagnetic field, the robotic garden tool including a body, one or more wheels coupled to the body, a working tool coupled to the body, and a first sensor set coupled to the body. Where the first sensor set includes a first sensor configured to detect the orientation and magnitude of the electromagnetic field along a first detection axis, and a second sensor configured to detect the orientation and magnitude of the electromagnetic field along a second detection axis and output a signal representative thereof. The garden tool also including a controller in operable communication with the first sensor set, where the controller is configured to determine the relative location of the boundary wire with respect to the first sensor set based at least in part on the signals output by the first and second sensors.
