A device for stacking a plurality of partially connected labels into a plurality of partially connected pads of labels comprises a robot arm having at least one vacuum source configured to selectively supply a vacuum force. The device also includes a plate coupled to the robot arm and a flexible pad coupled to the plate and including a plurality of apertures configured to direct the majority of the vacuum force through the flexible pad to a surface of the plurality of partially connected labels.

An axially mounted non-circular hole saw device follows a lateral, oscillating cutting motion to cut a non-circular kerf in a workpiece. The device adapts to variously styled power tools. The device couples to a power tool at an axial orientation through a mounting portion. The axial disposition of the device relative to the power tool enables the axial vibratory force generated by the power tool to convert to a lateral, oscillating cutting motion followed by the device. This cutting motion forms a clean non-circular kerf, offsets vibrations during cutting, and minimizes debris formed during cutting. A cutting portion has a non-circular shape. The cutting portion includes a base edge and a teeth edge. A bridge traverses the base edge for stability. A mounting portion extends perpendicularly from the bridge portion. The mounting portion includes a gap defined by slots that couple to a coupling mechanism from the power tool.

A method and apparatus for protecting a structure. A surface of the structure may be identified from a model of the structure. A perimeter of the surface of the structure may be identified from the model. The perimeter may be identified for the surface of the structure to be covered by a masking system during painting of the structure. A two-dimensional representation of the masking system may be generated for the structure based on the perimeter of the surface of the structure. Features for the masking system may be generated within the two-dimensional representation. Identifiers may be assigned to the features in the two-dimensional representation. Instructions for a forming tool may be generated based on the identifiers. The masking system may be formed from a sheet of masking material using the forming tool based on the instructions.

Systems and methods related to cutting (e.g., ultrasonically cutting) metals (e.g., lithium metal) and electrode precursors are generally provided. The electrodes or electrode precursors may involve, for example, a lithium metal electrode or a lithium composite electrode, e.g., for use in an electrochemical cell or battery.

A flat die magnetic holding base is provided for holding a metallic, flat die. The base can be formed from a metal plate having a front surface and a planar back surface. The front surface can include a planar mounting area. The planar back surface can have a plurality of recesses formed therein. The metal plate has three or more corners, each corner having a through-hole formed therein. Magnets are permanently fixed in recesses formed in the back surface. The magnets are oriented in the recesses such that a magnetic field is generated by the magnets in a direction that magnetically attracts and holds a metallic, flat die, to and on, the planar mounting area. The flat die can be a magnetically-attractable, milled-plate, flexible die. Alignment pins extend away from the planar mounting area and align with through-holes of the metallic, flat die to register the metallic, flat die on the mounting area.
