Abstract: A control system for off-highway battery application powertrain systems that allows the operator to select one or more performance/operating modes. The one or more performance modes may be based on the work that needs to be accomplished using the machine vs. the hours needed before the next charge opportunity. Modes will take typically into consideration battery management system performance maps, Electric motor/inverter performance maps, pump performance maps and other systems communicating with the powertrain system. The operator is in control to optimize refill and/or next battery charge. The operator may have the option to select performance modes based on excavator performance vs. battery life. Remaining time and warning messages may be periodically sent to the operator based on the performance mode selected and current state of charge.

Abstract: A method includes detecting a change in a loading condition on an engine based on use of an implement system including a pump driven by the engine, an actuator fluidly coupled to the pump, and an implement repositionable with the actuator. The change in the loading condition is detected based on a variation in a command signal from a joystick that controls movement of the implement, an outlet pressure of the pump, a displacement of the pump, and/or an engagement signal of a clutch positioned to selectively couple the pump to the engine. The method further includes commanding a fueling system to increase an amount of fuel provided to the engine and/or an air handling system of the machine to increase an amount of air and/or a boost pressure of the air provided to the engine in response to detection of an increasing loading condition based on the variation.

Abstract: Hairstyle transfer is challenging due to hair structure differences in the source and target hair. Latent Optimization of Hairstyles via Orthogonalization (LOHO) is an optimization-based approach using GAN inversion to infill missing hair structure details in latent space during hairstyle transfer. Hair is decomposed into three attributes: perceptual structure, appearance, and finer style, and includes tailored losses to model each of these attributes independently. Two-stage optimization and gradient orthogonalization enable disentangled latent space optimization of the three hair attributes. Using LOHO for latent space manipulation, users can synthesize novel photorealistic images by manipulating hair attributes either individually or jointly, transferring the desired attributes from reference hairstyles.
