  • Patent number: 11999012
    Abstract: A system for manufacturing of a sintered wire and in-situ feeding to a laser wire welding system is presented. The system includes a pressure vessel connected to a powder feed system for delivering at least two powders to a powder mixing zone of the pressure vessel. The at least two powders are mixed via a rotating cone in the pressure vessel. After mixing, a heating device contained within the pressure vessel heats the mixture so that liquid phase sintering occurs and a sintered rod is created. The sintered wire is continuously fed to a laser metal deposition system for depositing a layer of additive material on a base material. A method of additively manufacturing or repairing a superalloy component is also presented.

  • Patent number: 11989045
    Abstract: Low drop-out (LDO) regulator circuits and methods that can operate at high frequencies without the adverse consequences of an oscillatory resonance effect from a capacitive load. In a first embodiment, a low pass filter (LPF) is coupled to the LDO and tuned to cancel the oscillatory resonance effect. In a second embodiment, the LPF is a second-order LPF and/or programmable. Since the tuning values of the programmable LPF may be programmatically selected, a much greater range of external capacitors values (with attendant ESR and ESL values), as well as a wider range of system parasitic capacitances, can be accommodated while maintaining system stability. Some variants of the second embodiment include an oscillation detector and filter bit control circuit that allows the tuning values of the programmable LPF to be dynamically determined and re-determined. An impedance-lowering device may be coupled to lower the impedance of the connection to the LPF.

  • Publication number: 20240089118
    Abstract: A system and a method are disclosed for receiving a set of rules associated with a document type from a supplier entity. Each rule identifies a set of conditions and a set of actions to be taken after a document of a document type is signed if the set of conditions is satisfied. When a supplier entity sends a document of the document type to a signing entity and the signing entity provides an electronic signature, the system determines whether conditions of rules associated with the document type are satisfied. For each rule that is satisfied, the system performs actions identified by the rule.

  • Patent number: 11899411
    Abstract: A method includes determining a current state of an environment of an autonomous agent, such as a vehicle. The method also includes determining, via a first neural network, a set of actions based on the current state. The method further includes determining whether further analysis of the set of actions is desired. The method selects an action from the set of actions using a model-based solution based on a reward and a risk of the action when further analysis is desired. The method also includes selecting the action from the set of actions according to a metric when further analysis is not desired. The method controls the autonomous agent to perform the selected action.

  • Publication number: 20230345453
    Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.
