A gardening and/or forestry system includes a distance measuring system, including a first distance part and a second distance part, wherein the second distance part is configured to be carried on a body of a gardener and/or forestry worker. The distance measuring system is configured to exchange a measuring signal between the first distance part and the second distance part and to measure a distance between the first distance part and the second distance part based on the exchanged measuring signal. An output device is configured to output information based on the measured distance to the gardener and/or forestry worker.

Disclosed is a portable, mechanical saw guide, system, and process for using the same. The saw guide includes a housing, boom, and finger member that creates a comparative measurement basis for cutting wood.

A cutting guide for a saw includes a blade lying in a cutting plane. The cutting guide includes a bracket configured to be removably rotationally attached to the saw. The bracket includes a light clamp, a saw clamp, and a light emitter contained therein a sealed housing. The saw clamp is configured to removably rotationally attach the bracket to the saw, and the light emitter is removably attached to the bracket via the light clamp. The saw clamp is configured to rotate the light emitter in a pivot plane about a pivot axis parallel to the cutting plane. The saw clamp includes a first portion and a second portion each configured with female cylindrical surfaces to clamp to a grasping handle of the saw. The light clamp is a compression clamp configured to hold the light emitter in place. The light emitter includes a laser.

Chainsaw guide bar measuring attachment systems and methods are provided. A measuring device for defining a cut location for a chainsaw may include a length indicator, an attachment portion for positioning through an aperture defined in a guide bar of the chainsaw, and a fastening assembly for coupling to the attachment portion. The fastening assembly may include a fastener and a magnet. The fastener may couple the fastening assembly to the attachment portion. The magnet may magnetically couple the fastening assembly to the guide bar. A system may include a chainsaw and the measuring device for defining a cut location for the chainsaw. Corresponding methods are also provided.

A cutting guide for a saw having a blade lying in a cutting plane, the cutting guide comprising: a bracket configured to be attached to the saw; the bracket comprising a light clamp and a saw clamp; a light emitter removably attached to the bracket; the bracket configured to rotate the light emitter about a pivot axis parallel to the cutting plane about a pivot axis.

The measuring device described herein relates to an automatic wood marker attachment device. The device can be selectively attached to a chainsaw or power saw. More specifically, the device is clamped to the handlebar of a chainsaw or power saw using clamping arms. A pair of independently operating and articulating laser sources are used for projecting linear laser beams. The laser beams provide markings on a wood log to enable an operator to make accurate and precise cuts using the automatic laser markers. The laser sources are controlled using a control button to independently operate the laser sources. Further, the laser sources can be adjusted to any desired angle to allow automatic marking at any predeterminable direction and spacing.

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).

A new structural arrangement for an ancillary cutting device for chainsaws, pertaining to the technical sector of mechanics, particularly to the sector of cutting equipment. The device is coupled to the chainsaw to adjust the thickness of the timber to be cut. The device is secured to the body of the chainsaw or directly to the blade, and comprises a tubular body with a screw thread and nut at one end, and a channel at the opposite end that limits movement of a gauge whose positioning is set using markings on the tubular body. The gauge is formed by a sleeve having a diameter slightly larger than that of the tubular body. The sleeve has a cylindrical shoulder having a through-hole with an inner thread for receiving a fastening screw, and a support rod obliquely relative to the axis thereof

An outdoor power tool may include an engine, a working assembly that performs a cutting operation powered by the engine, movement sensor circuitry configured to at least determine movement information of the outdoor power tool using inertia based measurements locally determined at the outdoor power tool, and a position monitoring module including processing circuitry configured to receive the movement information and receive an input defining a reference point. The position monitoring module may be further configured to provide feedback to an operator of the outdoor power tool to direct operation of the outdoor power tool based on the movement information.

A motorized chain saw has a measuring system for measuring an object, in particular a trunk. The motorized chain saw has a saw chain, and the measuring system has an evaluation device. The measuring system includes a sensor system for capturing the movement of the saw chain as the saw chain rolls over an object to be measured. The evaluation device is configured to evaluate the movement of the saw chain captured by the sensor system. In a method for operating the motorized chain saw, the sensor system captures the movement of the saw chain as the saw chain rolls over an object to be measured, and the evaluation device evaluates the captured movement.
