  • Publication number: 20240384707
    Abstract: A wind turbine planet gear shaft has a shaft body with an outer surface, a segment of the outer surface being a slide bearing surface configured to form a radial slide bearing with an inner opening of a planet gear. The slide bearing surface has a first portion configured as a non-load-bearing zone and a second portion configured as a load-bearing zone and exactly one axially elongate oil pocket in the slide bearing surface, that oil pocket being located in the non-load-bearing zone. An oil supply channel in the shaft body has a first end in communication with the oil pocket, and first and second oil return channels in the slide bearing surface each have a first end at a longitudinal end of the oil pocket and a second end open to ambient air.

  • Patent number: 12146447
    Abstract: Systems and methods for improving engine low load performance are provided. The method may comprise performing a negative valve overlap (NVO) mode of operation, using an early exhaust valve closing (EVC) timing that is earlier than the intake valve opening timing and creates an NVO during a gas exchange top dead center, to compress in-cylinder gas and increase overall gas temperature for improved fuel vaporization, mixing, and reforming before the fuel-air mixture is burnt. With NVO operation, a low temperature combustion (LTC) mode may be used to improve engine combustion efficiency and reduce emissions. With the NVO operation at low loads, the engine intake may be wide open or less throttled, reducing pumping loss. A method based on a rate of change in the engine speed and load for the combustion mode transition between spark ignition (SI) and LTC modes is provided.

  • Patent number: 12132453
    Abstract: Embodiments of RF amplifiers and packaged RF amplifier devices each include an amplification path with a transistor die, and an output-side impedance matching circuit having a T-match circuit topology. The output-side impedance matching circuit includes a first inductive element connected between the transistor output terminal and a quasi RF cold point node, a second inductive element connected between the quasi RF cold point node and an output of the amplification path, and a first capacitance connected between the quasi RF cold point node and a ground reference node. The RF amplifiers and devices also include a baseband termination circuit connected to the quasi RF cold point node, which includes a third inductive element, a resistor, and a second capacitance in series between the quasi RF cold point node and the ground reference node and a third capacitance between a baseband termination circuit node and the ground reference node.

  • Patent number: 12123369
    Abstract: An internal combustion engine system and methods of use are provided. The internal combustion engine system may comprise an engine chamber with a piston, and one or more of the following, configured to enable a negative valve overlap (NVO) mode of operation in which an intake valve opening (IVO) timing is later than an exhaust valve closing (EVC) timing: a continuously variable valve duration (CVVD) mechanism for both an intake valve and an exhaust valve; a dual CVVD and continuously variable valve timing (CVVT) mechanism for both the intake valve and the exhaust valve; and a cam system. The internal combustion system may comprise a fuel delivery system comprising one or more of a direct injector and a port fuel injector; and may comprise an ignition system.

  • Patent number: 12108493
    Abstract: Role switch between wirelessly paired master/slave devices may be performed without perceived glitches in audio. The devices negotiate an anchor point, such as a point in time or a point in relation to other events, for performing the role switch. To prepare for the role switch prior to the anchor point, the devices communicate a variety of information, such as information for communicating with the host device after the role switch and information for bit processing after the role switch. The slave device may use such information to serve in the master role, without the host knowing that a role switch occurred.

  • Patent number: 12038802
    Abstract: Classifying wafers using Collaborative Learning. An initial wafer classification is determined by a rule-based model. A predicted wafer classification is determined by a machine learning model. Multiple users can manually review the classifications to confirm or modify, or to add user classifications. All of the classifications are input to the machine learning model to continuously update its scheme for detection and classification.
