A hand-guided garden, forestry and/or construction working apparatus has an inactive state, an active state and a variable setting, as well as an apparatus operator control element which can be activated by a user. In the inactive state, the garden, forestry and/or construction working apparatus is designed to be transferred into the active state triggered by activation of the apparatus operator control element, and in the active state the garden, forestry and/or construction working apparatus is designed to change the setting and not to be transferred into the inactive state triggered by activation of the apparatus operator control element.

An autonomous vehicle apparatus and method for performing pruning operations on a plant being cultivated in a container is disclosed. The apparatus includes a wheeled chassis operably configured to autonomously navigate to a location of the container within a workspace. The apparatus also includes a plant support operable to receive and secure the container in an upright condition with respect to a vertical axis extending generally vertically through the container and the plant. The apparatus further includes a manipulator mounted to the vehicle and operable to grasp and load the container onto the plant support, and a pruning tool mounted on the vehicle and disposed to prune the plant while causing rotational movement of at least one of the pruning tool and the container about the vertical axis.

The present disclosure discloses a signal generator based on inductance characteristics of an element, an electric shearing tool, and a shear opening degree control method for an electric shearing tool, and relates to the technical field of electric shearing tools. A changeable inductance value of an inductance type transducer is obtained through a change in a relative position between a triggering member and the inductance type transducer. The inductance value is increased or decreased linearly, so that a control processor can precisely obtain relative position information between the triggering member and the inductance type transducer according to linear changes of the inductance value, thereby obtaining position information of a blade travel control member. Each position point can be mapped to current positions of blades.
