  • Patent number: 11140939
    Abstract: Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

  • Patent number: 10773331
    Abstract: Methods and apparatus to communicate via a weld cable are disclosed. An example welding-type power supply includes a power converter, a receiver circuit, and a controller. The power converter converts input power to welding-type power based on a weld voltage setpoint and to output the welding-type power via a weld circuit. The receiver circuit receives a communication via the weld circuit while current is flowing through the weld circuit or after the current has stopped flowing through the weld circuit. The communication includes weld voltage feedback information measured at a device remote from the power supply while the current is flowing through the weld circuit. The controller controls the welding-type power output by the power converter according to a voltage feedback loop using the weld voltage feedback information to regulate a weld voltage at the remote device to the weld voltage setpoint.
