摘要： A robotic working tool comprising a sensor for detecting magnetic fields connected to a controller for controlling the operation of the robotic working tool. The controller is configured to operate according to a first control signal being transmitted through a first boundary wire and according to a second control signal being transmitted through a second boundary wire. The robotic working tool is thereby configured to operate within a composite work area comprising at least a first partial work area and a second partial work area. The first boundary wire delimits the first partial work area and the second boundary wire delimits the second partial work area. The at least first and second boundary wires provide a common perimeter for the composite work area. Analysing the magnetic fields detected by the sensor, the controller determines whether the robotic working tool is inside or outside the composite work area.

摘要： The present disclosure relates to a drill tool (1), such as a core drill tool (1), comprising a motor unit (2) and a gear unit (3). The motor unit (2) comprises an electric motor (4) and a motor drive shaft (5) that extends along a first longitudinal axis (6) from the electric motor (4) and protrudes out of a motor unit housing (7) via a motor exit aperture (8) in a housing end part (9) and comprises a drive shaft gear (10). The drive shaft gear (10) is adapted to propel a drill shaft (14) that extends along a second longitudinal axis (15) and comprises a tool holder (16) that is adapted to hold a tool. The housing end part (9) comprises a wall part (17) arranged transversally to the longitudinal axes (6, 15) and is adapted to close the gear unit cavity (11) and to separate the electric motor (4) from the gear unit cavity (11).

摘要： A riding lawn care vehicle (10) may include a frame (60), a steering assembly (30), a brake assembly (110), and a mechanical brake linkage assembly (120). At least a first drive wheel (32) and a second drive wheel (32) of the riding lawn care vehicle (10) may be attachable to the frame (60). The steering assembly (30) may include a first steering lever (34) and a second steering lever (34), where the first and second steering levers (34) are operably coupled to the first and second drive wheels (32) respectively to facilitate turning of the riding lawn care vehicle (10) based on drive speed control of the first and second drive wheels (32) responsive to positioning of the first and second steering levers (34) along a first direction when the first and second steering levers are in an operating position. The brake assembly may be operably coupled to the first and second drive wheels (32) to enable brakes to be selectively applied to the first and second drive wheels (32). The mechanical brake linkage assembly (120) may be configured to activate the brake assembly (110) relative to the first and second drive wheels (32) in response to movement of the first and second steering levers (34)

摘要： An adjustment assembly for adjusting a position of one of a pair of steering levers of a riding lawn care vehicle that has first and second drive wheels may include a sleeve, a base portion and a rotatable adjuster. The steering levers may be operably coupled to respective ones of the first and second drive wheels to selectively control the riding lawn care vehicle based on drive speed control of the first and second drive wheels responsive to positioning of the steering levers along forward and rearward directions. The sleeve may be operably coupled to one of the steering levers and the base portion may be operably coupled to the sleeve via a pivot coupling. The pivot coupling is configured to reposition the sleeve relative to the base portion along the forward and rearward directions responsive to operation of the rotatable adjuster to define non-discrete fixing relationships between the sleeve and the base portion along the forward and rearward directions.

摘要： An apparatus (e.g., robotic vehicle, control device, headpiece, etc.) including processing circuitry (110) configured to receive robotic-vehicle-positioning-information indicative of robotic vehicle position data of a robotic vehicle (20) transiting a work area at one or more locations on the work area; receive operator-positioning-information indicative of operator position data of an operator controlling the robotic vehicle (20); generate a virtual line-of-sight vector (70) based on the operator-positioning-information; generate a virtual sight area (80) based on the virtual line-of-sight vector (70) and a predetermined sight area parameter; determine if the virtual sight area (80) intersects with the robotic-vehicle-positioning-information; and initiate one or more precautionary measures when the virtual sight area (80) does not intersect with the robotic-vehicle-positioning-information.

摘要： A coupling may be configured to receive and secure an insertion end of a conduit. An outer surface of the insertion end of the conduit may be smooth and free of grooves, flanges and beads. A first member of the coupling may define a first passageway. A second member of the coupling may define a second passageway. The first member may be in engagement with the second member. A gripping ring having an inner edge defining a series of teeth may be disposed within the second member. A support ring and O-ring may also be disposed within the second member.
