Publication number: 20210316394Abstract: A laser cutter and safe power system therefor are disclosed. The power system of the laser cutter includes a resistive device arranged in a return line and configured to prevent anomalous tripping of a GFCI device by significantly minimizing electrical noise transmitted through the GFCI device when the laser cutter is operated in certain modes, such as a pulsing mode. The resistive device includes end caps that form a shroud around the connection between a return wire and the contact at each end of the resistive device. A main control board for a high voltage subsystem of the power system includes two isolated and independent enable signals, which are provided to different controllers on the main control board such that the different controllers can independently and redundantly respond to an unsafe condition.Type: ApplicationFiled: August 23, 2019Publication date: October 14, 2021Inventors: Gregory A. Herman, James Randall Cooper, Walter Bernardi, Bradley D. Padget, Richard M. Ness, Emory Wheeler

Patent number: 10906108Abstract: An accessory includes a blade, a coupling, and a guide. The blade includes a cutting edge. The coupling includes a first portion and a second portion. The first portion is attachable to and detachable from the power tool. The second portion is connected to the blade. The guide is structured to guide the blade along a work piece by interacting with a surface of the work piece as the blade moves in an advancing direction. The guide is structured to provide a locked state and an unlocked state. In the locked state, the guide is engaged with the coupling such that the guide is attached to the coupling. In the unlocked state, the guide is disengaged from the coupling such that the guide is detached from the coupling.Type: GrantFiled: April 24, 2018Date of Patent: February 2, 2021Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventors: Jeremy Rubens, Walter Bernardi

Patent number: 10427230Abstract: A blade for oscillating tools includes lateral edges, a working edge that extends in a first direction, and a mounting portion. The mounting portion includes a first mounting configuration that defines a first center and a second mounting configuration that defines a second center, where the first center is spaced a distance away from the second center in a direction that is substantially orthogonal to the first direction in which the working edge extends or to a tangent of a center of curvature of the working edge. Both mounting configurations are configured to drive the same working edge.Type: GrantFiled: April 4, 2017Date of Patent: October 1, 2019Assignee: Robert Bosch GmbHInventors: Walter Bernardi, Arvind Gopi, Saad Alam

The cam post is rotatable with the cam. The handle is movable into a first position and a second position. The handle plate is rotatable with the handle. The handle plate is configured to rotate the cam post in a first direction when the handle moves from the first position to the second position. The handle plate is configured to rotate in a second direction without rotating the cam post in the second direction for a predetermined distance when the handle moves from the second position to the first position. The first direction is opposite to the second direction.Type: GrantFiled: March 28, 2017Date of Patent: February 26, 2019Assignees: Robert Bosch Tool Corporation, Robert Bosch GmbHInventors: Walter Bernardi, Daniel Schadegg
