In a battery charging system (), a charger () and a smart battery () enhance safety in recharging a cell () in the smart battery () by a power supply () of the charger (). The smart battery () is communicable with the charger (). If a communication failure occurs, the charger () disconnects the power supply () from the smart battery (). The smart battery () and the charger () share the same symmetric encryption key for encrypting and decrypting message data, allowing one party to determine if the other part is an authentic one. When the smart battery () finds that the charger () is not authentic, or vice versa, the power supply () and the cell () are disconnected. When the smart battery () finds that a no-charging condition occurs due to abnormality in the cell (), the smart battery () requests the charger () to stop charging, and also disconnects the cell () from the charger () even if the charger () fails to stop charging the smart battery ().

Smart battery, charger and battery charging system

A communication system may include a robotic garden tool with an electronic processor that may be configured to determine (i) a plurality of relative distances between the robotic garden tool and an object as the object moves in the operating area, and (ii) one or more locations of the robotic garden tool as the object moves in the operating area. The electronic processor may be further configured to determine a respective location of the one or more locations of the robotic garden tool at a respective time at which data was captured that allowed for the determination of each relative distance of the plurality of relative distances. A virtual boundary may be generated using each relative distance in combination with the respective location of the robotic garden tool at the respective time at which the data was captured that allowed for the determination of each relative distance.

Creation of a virtual boundary for a robotic garden tool

A method of operating a mowing system, the method including mowing within a work area, wherein mowing is performed by a robotic lawn mower, and wherein the work area comprises a plurality of base stations each configured to charge the robotic lawn mower; determining when to charge the robotic lawn mower in view of a current charge level and a current location of the robotic lawn mower.

Robotic lawn mowers

A mowing system including a base station disposed at a work area; and a plurality of robotic lawn mowers disposed at the work area, the plurality of robotic lawn mowers including a first robotic lawn mower and a second robotic lawn mower, wherein the base station is configured to communicate with the second robotic lawn mower through the first robotic lawn mower.

An interface () between a battery and an electrical device, the interface () comprising: a male terminal () and a female terminal () configured to receive the male terminal (); the female terminal () having a female contact () of conductive material and the male terminal () having a male contact () of conductive material; wherein, at least one of the female contact () and the male contact () are resiliently deformable such that insertion of the male terminal () in the female terminal () provides an area () of face to face contact in which the male contact () and the female contact () conform to each other.

Battery interface for an electrical device

A blower, comprising: a blower body, having accommodated therein a fan and a drive unit, a rotation shaft of the fan defining a longitudinal axis, and the blower body defining an air inlet; a blow pipe, attached to the blower body and extending along the longitudinal axis, the blow pipe defining an air outlet; and a control unit, for controlling operation of the drive unit. The blower defines an airflow path extending from the air inlet to the air outlet, the control unit being at least partially located in the airflow path, such that when the blower is operating, at least a portion of an airflow entering the air inlet cools the control unit and is then discharged through the air outlet.
