Patent number: 11690315Abstract: An autonomous lawn mower includes removable batteries, one or more electric motors, a cutting blade, one or more wheels, an angle sensor, and a controller. The cutting blade is driven by one of the electric motors. The wheels are driven by one of the electric motors. The controller is configured to allow the lawn mower to perform a grass cutting function at a jobsite without human interaction. The controller is configured to determine whether a roll angle is greater than a first predefined amount using data from the angle sensor. In response to determining the roll angle is greater than the first predefined amount, the controller is configured to stop operation of one of the one or more electric motors configured to provide rotational drive power to the cutting blade.Type: GrantFiled: November 11, 2021Date of Patent: July 4, 2023Assignee: Briggs & Stratton, LLCInventors: Jeffrey M. Zeiler, Ryan T. Hahn, Kyle Harvey, Todd Johnson, Robert Pjevach, Jacob Schmalz, Peter D. Shears, Nicholas Zeidler

Publication number: 20030178796Abstract: The quick-release chuck for a rotary power tool is provided for holding a tool bit. The chuck includes a barrel having an axial bore to receive the tool bit and an axially movable sleeve operable to position a locking member to selectively lock or release the tool bit. A proximal end of the chuck near the housing of the power tool includes a low-profile collar which holds a spring in compression against the sleeve, biasing the sleeve in a distal, locked position. The components of the chuck may advantageously be assembled in a stacked manner. The low-profile collar permits the chuck to occupy a minimal length and to be positioned with a minimal separation from the housing of the power tool for enhanced safety.Type: ApplicationFiled: March 19, 2002Publication date: September 25, 2003Inventors: Robert Pjevach, Brady Groth
