Abstract: Some examples described herein relate to modifying avatars in user interfaces based on wearable device data using machine learning. For example, a system can receive, from a wearable device, a set of biological data with respect to a user wearing the wearable device. The user can be associated with an avatar of the user on a user interface. The system can provide the avatar of the user and the set of biological data as input to a trained machine-learning model. The trained machine-learning model can generate a modified avatar based on the input. The system can then receive the modified avatar as output from the trained machine-learning model. The system can modify the user interface to include the modified avatar. The modified avatar can be outputted for display on a client device.

Abstract: A method of heat treating a workpiece, the method including projecting a laser beam from a laser source onto said workpiece, so as to produce a laser spot on said workpiece; projecting the laser spot onto different portions of said workpiece; and while projecting the laser spot, repetitively scanning the laser beam in two dimensions so as to produce a two-dimensional equivalent effective laser spot on said workpiece and thereby temper, reduce hardness of, enhance ductility of, and/or reduce brittleness of at least one of the different portions of the workpiece.

Abstract: A method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft, including the steps of generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of the surface area, and during the relative movement, repetitively scanning the laser beam so as to produce a two-dimensional equivalent effective laser spot on the surface area. The energy distribution of the effective laser spot is adapted so that it is different in a more heat sensitive subarea, such as in an area adjacent to an oil lubrication opening, than in a less heat sensitive subarea, so as to prevent overheating of the more heat sensitive subarea.

Abstract: Method of laser hardening of a surface area of a workpiece, such as a surface of a journal of a crankshaft, comprising: generating a relative movement between the surface of the workpiece and a laser source to allow a laser spot to subsequently be projected onto different portions of said surface area, and during said relative movement, repetitively scanning the laser beam (2) so as to produce a two-dimensional equivalent effective laser spot (5) on said surface area. The energy distribution of the effective laser spot is adapted so that it is different in a more heat sensitive subarea, such as in an area adjacent to an oil lubrication opening, than in a less heat sensitive subarea, so as to prevent overheating of said more heat sensitive subarea.
