A selectively operable door () for a robotic vehicle () may include a doorframe disposable in a barrier dividing two areas in which the robotic vehicle () is enabled to travel, a door body () hingedly connected to the door frame (), and a latching assembly configured to alternately allow movement of the door body () such that the robotic vehicle () to enabled to pass through the selectively operable door () via displacement of the door body () and prevent movement of the door body () such that the door body () is retained in a closed state. The latching assembly may include an automatic lock configured to define a release position in which movement of the door body () from the closed state is allowed, and a capture position in which movement of the door body to the closed state is allowed and movement of the door body from the closed state is prevented.

Selectively operable door for an autonomous device

A starting assembly for a backpack blower may include a starting lever. The backpack blower may include an engine and a backpack harness configured to support the blower on a back of a user wearing the backpack harness. The starting lever may include a lever arm operably coupled to an axial member at a distal end of the axial member. The starting lever may be pivotable about an axis formed by the axial member by a user wearing the blower via the backpack harness to start the engine.

Backpack blower with improved starting mechanism

A blower may include a housing having a handle, an electric motor powered by a battery pack, and a fan assembly operably coupled to the electric motor to force air through a blower tube responsive to operation of the electric motor. The blower tube defines a blower tube axis. The fan assembly creates a low pressure area in a intake chamber that provides the air to the fan assembly. The air enters the intake chamber via at least one radial entrance and an axial entrance disposed in the housing. The axial entrance is configured to receive cooling air that has passed through the battery pack.

Herein a chainsaw () is disclosed comprising a guide bar () and a chain () moveably arranged around the guide bar (). The chainsaw () comprises an motor () comprising a motor shaft (), wherein the motor () is configured to drive the chain () via the motor shaft (). The chainsaw () further comprises a tension estimation arrangement () configured to sense a load on the motor shaft (), and configured to estimate the tension of the chain () around the guide bar () on the basis of the sensed load on the motor shaft (). The present disclosure further relates to a method of estimating tension of a chain () of a chainsaw ().

Chainsaw and method

A hand-held power tool may include a housing, a power unit disposed within the housing and configured to operate at least in part in response to actuation of a trigger, a working assembly powered responsive to operation of the power unit, and an activation lever having an integrated lockout member. The activation lever may selectively engage a first fuel enrichment mode associated with startup of the power unit in a first range of ambient temperatures and a second fuel enrichment mode associated with startup of the power unit in a second range of ambient temperatures based on a position of the activation lever. Selective engagement of the first fuel enrichment mode or the second fuel enrichment mode may be enabled responsive to actuation of at least the lockout member and positioning of the activation lever.
