Abstract: A machine task tutorial system is disclosed that utilizes augmented reality to enable an expert user to record a tutorial for a machine task that can be learned by different trainee users in an adaptive manner. The machine task tutorial system advantageously utilizes an adaptation model that focuses on spatial and bodily visual presence for machine task tutoring. The machine task tutorial system advantageously enables adaptive tutoring in the recorded-tutorial environment based on machine state and user activity recognition. The machine task tutorial system advantageously utilizes AR to provide tutorial recording, adaptive visualization, and state recognition. In this way, the machine task tutorial system supports more effective apprenticeship and training for machine tasks in workshops or factories.

Abstract: The present disclosure provides a heat exchanger for a power system. The heat exchanger includes a housing. The housing includes a first side and a second side. The second side is configured to be received in a receptacle of a power system enclosure. The heat exchanger includes at-least one heat exchange tube supported between one or more of side walls of the housing. The heat exchanger includes a screen attached to the second side of the housing. The screen includes at-least one inlet opening for the heat exchange tube, and at-least one outlet opening for the heat exchange tube. The heat exchanger further includes a flange attached to the first side of the housing wherein the flange is configured to be removably attached to an outer surface around the receptacle of the power system enclosure.
