Publication number: 20240238903Abstract: Methods and systems are provided for softening a feature of a workpiece. A method for feature softening includes generating a nominal path for softening the feature. Defining points of the workpiece are selected for accuracy of the softening. The workpiece is formed, fixtured in a workstation and imaged. From the imaging and by a processor, an actual location of the defining points on the workpiece as formed and fixtured in the workstation is determined. The processor determines an error between the actual location of the defining points and the design location of the defining points; generates a revised path for softening the feature of the workpiece; guided a material movement machine along the revised path; and softens, by the material movement machine, the feature of the workpiece.Type: ApplicationFiled: January 17, 2023Publication date: July 18, 2024Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Jerone Spencer Anderson, William P Payne

Publication number: 20240239349Abstract: A system, e.g., an autonomous vehicle, includes a sensor suite, a controller, and a computer-controllable device. The sensor suite collects user data descriptive of the present emotional state of a human user, such as a passenger of the representative autonomous vehicle. The controller executes a method to control the system. In particular, the controller identifies the user's psychological mode of experience in response to the user data. The controller also selects one or more intervening control actions or “interventions” from a list of possible interventions based on the mode of experience, and then controls an output state of the device to implement the intervention(s). In this manner the controller is able to support or modify the mode of experience of the user.Type: ApplicationFiled: January 12, 2023Publication date: July 18, 2024Applicants: GM GLOBAL TECHNOLOGY OPERATIONS LLC, B.G.
