  • Publication number: 20250128619
    Abstract: A work machine that is powered by batteries in a power unit uses a locally distributed electrical system and a locally distributed hydraulic system. A portion of power from the power unit is provided to an inverter installed in a front section of the work machine to power electrical equipment installed in the front section. Another portion of the power from the power unit is provided to an inverter installed in a rear section of the work machine to power electrical equipment installed in the rear section. Additionally, a hydraulic pump installed in the front section pressurizes hydraulic fluid in a front accumulator for use by hydraulic loads in the front section and a hydraulic pump installed in the rear section pressurizes the hydraulic fluid in a rear accumulator for use by hydraulic loads in the rear section.

  • Patent number: 12282323
    Abstract: A vacuum system includes at least one cryopump; sensors associated with the cryopump, each of the sensors being configured to sense an operating condition of the cryopump; and diagnostic circuitry configured to receive signals sampled from the sensors. The diagnostic circuitry includes a diagnostic model of the cryopump, the diagnostic model being derived from historical data of a plurality of cryopumps of a same type operating over a plurality of regeneration and servicing time periods and being configured to relate values of the sampled signals from the at least some sensors to a probability of the pump failing within a predetermined time. The diagnostic circuitry is configured to apply the sampled signals to the diagnostic model and to determine the probability of the at least one cryopump failing within a predetermined time from an output of the model.

  • Patent number: 12162359
    Abstract: A ground movement system for a land transport vehicle (2) capable of levitating, the vehicle having a plurality of wheels including at least one actuated wheel (3), a drive device (6) for driving the actuated wheel and/or a brake (8) for braking the actuated wheel (3), a vertical positioning actuator (9) arranged to move the actuated wheel (3) vertically relative to a fuselage of the vehicle (2), and control means arranged to act, during an acceleration stage and/or during a braking stage of the vehicle, to control the vertical positioning actuator (9) as to adjust the vertical position of the actuated wheel in order to increase the load carried by the actuated wheel and thus increase the maximum force that can be transmitted to the ground by the actuated wheel so as to increase the maximum drive and/or braking torque that can be produced by the drive device (6) and/or by the brake (8) without the actuated wheel (3) skidding or slipping.
