Method and kit for extracting and using auxiliary power
A method and kit for extracting auxiliary power from a power source installed on or associated with an implement, and supplying the auxiliary power to an auxiliary tool associated with the implement. The invention is preferably employed in the context of an auxiliary tool, e.g., in the form of a rotary trimmer, edger or the like, associated with another power implement, such as a lawnmower, wherein the power is preferably extracted from a driven member of the implement. Advantageously, the device is easy to attach/detach, is universally locatable and/or orientable on the implement, and is easily retrofittable to practically any existing implement, such as a lawnmower deck.
Communication channel between a robotic lawnmower and a charging station
A bidirectional communication channel between a robotic lawnmower and a charging station for data communication between the robotic lawnmower and the charging station. The communication channel includes a first interface provided on the robotic lawnmower and a second interface provided on the charging station. The first and second interface are connected to each other through charging contacts and configured to communicate data in a Direct Current, DC-balanced way. Each interface is provided with an inductor in a charging power path between the charging station and the robotic lawnmower. Each inductor includes a high impedance for enabling a high data transmission rate for frequencies above 50 kHz.
Apparatus and method for cooling lawnmower components
A lawnmower can include a deck, blade, electric motor, battery pack, housing and fan. An air inlet can be located at the front end of the housing and adjacent to the top surface of the deck. The fan can be mounted in the housing and the housing can be configured such that, when the fan operates, air enters the housing air inlet at the front end of the housing, air flowing through the housing air inlet enters the first chamber, air flowing in the first chamber flows through the battery pack, air exiting the first chamber enters the second chamber and flows through the second chamber, air flowing in the second chamber flows through the motor in a direction that extends along the blade axis, and air exiting the motor exits the housing through the at least one air outlet.

APPARATUS AND METHOD FOR POWERING A GARMENT
A lawn mower or stand-on powered drivable machine has an electrical port that receives current from an alternator powered by the engine or motor. The port receives a plug from a garment worn by the lawn mower operator. The garment includes one or more thermo-electric elements that are powered from current extending through the port. The thermo-electric (TEC) elements may be resistive heaters to warm the operator or TEC coolers to cool the operator. Furthermore, the garment may include a rechargeable battery that powers the thermo-electric elements when the plug is disconnected from the port.
