Abstract: The present invention provides a robot gardening tool system and a method for a robot gardening tool. The robot gardening tool system comprises a robot gardening tool and a boundary module. The boundary module delimits a work area and/or a non-work area of the robot gardening tool, and the boundary module comprises at least one boundary element. The robot gardening tool comprises a boundary detection apparatus, a jamming detection apparatus and a control apparatus. The boundary detection apparatus detects the at least one boundary element; the jamming detection apparatus judges whether the robot gardening tool is jammed based on a feedback signal Si of the boundary detection apparatus; and the control apparatus controls the robot gardening tool to perform an extrication operation when the robot gardening tool is jammed. The present invention also provides a method for a robot gardening tool. The robot gardening tool system and method for a robot gardening tool according to the present invention enable effective detection of jamming, reduce misjudgements, and can perform effective operations on work areas where jamming is likely.

Abstract: Systems and methods which provide control of lubricant delivery with respect to chainsaws using a lubricant flow shutoff valve controlled in correspondence to an operational state of the chainsaw are described. A chainsaw lubricant delivery control system may include a lubricant flow shutoff valve and a chainsaw operation-based valve controller operable cooperatively to provide control of lubricant delivery to the cutting chain and guide bar assembly of a chainsaw. The chainsaw operation-based valve controller may be coupled to an operationally active element of the chainsaw wherein the chainsaw operation-based valve controller may control the lubricant flow shutoff valve between an open position and a closed position responsive to detecting a particular state of the operationally active element corresponding to an operational state of the chainsaw. Chainsaw lubricant delivery may prevent or otherwise discourage unintended leakage of lubricant from the chainsaw lubrication system.

Abstract: The present disclosure is directed to a fastener driver for driving a fastener into a workpiece. The fastener driver includes a housing and a lever pivotably coupled to the housing and actuable to cause the fastener driver to drive the fastener into the workpiece. The fastener driver also includes fastener puller removably coupled to the housing and operable to remove the fastener from the workpiece. The fastener puller includes a base portion, a removal head, and a pivot region. The removal head is affixed to the base portion and configured to pry the fastener from the workpiece. The removal head has a flat shape. The pivot region is defined between the removal head and the pair of legs. The pivot region is configured to contact the workpiece such that during operation the fastener puller pivots about the pivot region relative to the workpiece.
