  • Patent number: 11883895
    Abstract: A plasma cutting system for measuring or monitoring the voltage between a plasma torch and the material being cut to determine a voltage or voltage signature and comparing that measurement against predetermined values to indicate that an initial pierce of the material is complete, and based on the measurement, moving the torch or the material to a different location for additional cutting. The system further provides a Fix Drawing Tool, which will automatically detect and fix gaps or overlaps in a drawing that are very difficult to find visually. These gaps and overlaps become a problem when trying to make a proper toolpath because a CAM program requires a clean, closed shape. The system also provides a Dynamic Corner Looping system, which automatically adjusts with the feed-rate and accelerations of the toolpath and plasma machine, eliminates unwanted dross, sharpens corners and minimizes material loss. A pendant tethering system is also disclosed for managing control of a CNC machine remotely.

  • Publication number: 20070057486
    Abstract: A stroller that accepts and supports various types of child's car seats is easily converted from its operational state to its storage state by actuating a latching mechanism. The stroller includes a lever which facilitates the removal of the child's car seat. A seat assembly can be attached to the stroller to convert the stroller from a child's car seat carrier to a toddler stroller. The seat assembly remains in the upright position when the stroller is converted from the storage state to the operational state.
