A handheld power tool (100) comprising at least one orientation sensor (150) is provided. The handheld power tool (100) is operatively connected to a controller (160; 210) and said controller (160; 210) is configured to receive orientation data from the at least one orientation sensor (150), wherein the orientation data comprises information associated with an orientation of at least a portion of the handheld power tool (100) and to determine operational data based on the orientation data, said operational data representing work performed using the handheld power tool (100). The operational data is determined by determining the orientation of the power tool based on the received orientation data from the at least one orientation sensor (150).

Described are systems and methods for treating and/or helping prevent microbial infections on plants and trees by applying a treatment solution to cut areas of the plants or trees that have been exposed during a hedging or topping operation, or the like. The method can include providing a liquid application system including treatment liquid, wherein the liquid application system is integrated with at least one of a motorized hedging and/or topping vehicle, wherein the liquid application dispenses the treatment liquid at a controlled rate of flow from the one or more nozzles and the treatment liquid is applied directly and uniformly from the one or more nozzles on the second boom to the one or more cut areas at the controlled rate of flow.

A garden and/or forestry system has a hand-held gardening and/or forestry processing apparatus, and an assistance device, which is formed separately from the gardening and/or forestry processing apparatus and which is designed to support a user in operation of the gardening and/or forestry processing apparatus. The assistance device has a user interface, by which the assistance device is controllable by user inputs. The hand-held gardening and/or forestry processing apparatus has a user-actuable operator control element for user inputs to the user interface.

A method for handling logs, wherein the method comprises the following steps:—retrieving or generating a unique code at a first moment;—establishing, by means of a position determining device, position information as to the geographical position of a portable, hand-held log marking tool (1) at said first moment;—applying the code as a corresponding code marking on a log by means of the log marking tool at a second moment and automatically establishing a time value representing the time elapsed between said first moment and said second moment;—comparing said time value with a predetermined time threshold value; and—storing the code as an authenticated code in a database associated to the position information when said time value is smaller than the time threshold value. The invention also relates to a log marking tool (1) for use in such a method.

A system assists during execution of a sequence of cuttings in a tree, wherein, during a cutting sequence, a first cut in the tree is followed by a second cut in the tree At least a part of an ideal course of the second cut depends on at least a part of a course of the first cut. An identification device identifies at least the part of the course of the first cut in the tree. A precalculation device precalculates at least the part of the ideal course of the second cut in the tree based on the identified part of the course of the first cut. An output device outputs cutting information for executing the second cut based on the precalculated part of the ideal course of the second cut.
