  • Publication number: 20260128040
    Abstract: In some embodiments, the techniques described herein relate to a method including: receiving, by a text or call processing program, a plurality of seed utterances each with a plurality of predefined seed labels; receiving a first user utterance; converting the plurality of seed utterances and the first user utterance into n-gram phrases; grouping n-gram phrases of the plurality of seed utterances into phrase pools based on whether the n-gram phrases are 2-gram phrases or 3-gram phrases; executing n-gram matching of the user utterance with a first seed utterance of the plurality of seed utterances; and assigning a first intent label to the first user utterance based on a match of 3-gram phrases with the first seed utterance of the plurality of seed utterances.

  • Publication number: 20240346410
    Abstract: A method and a system for using machine learning technology to optimize a scheduling strategy for establishing contact with a customer are provided. The method includes: receiving a data set that relates to a customer account; analyzing the data set to determine at least one proposed schedule for an attempt to contact the customer; and generating, based on a result of the analysis, a report that includes the proposed schedule. The analysis may be performed by applying a machine learning model that is trained by using historical data that relates to interactions associated with the customer.

  • Publication number: 20240338418
    Abstract: Various methods, apparatuses/systems, and media for accelerating decomposition via reinforcement learning are disclosed. A processor implements a decomposition algorithm that allows a solution of a comparatively larger linear programming problems that have a special block structure; inserts a reinforcement learning agent within a framework of the decomposition algorithm; and generates, in response to inserting the reinforcement learning agent, master problem decisions in place of an NP-hard (nondeterministic polynomial time-hard) mixed-integer master problem (MIMP).

  • Publication number: 20240327011
    Abstract: A system and method for selectively suspending the operation of aircraft systems based on prioritized system criticality in response to a high power demand from an aircraft engine. The method includes determining that a power demand on the aircraft engine will exceed a predetermined power limit, transmitting a suspend command to one or more of the aircraft systems in response to determining that the power demand on the aircraft engine will exceed the predetermined power limit, and causing the aircraft systems that receive the suspend command to enter a reduced power mode and not operate. The method also includes determining that the power demand on the one or more aircraft engines has been reduced below the predetermined power limit, and removing the suspend command and allow the aircraft systems that received the suspend command to operate as they were before receiving the suspend command.

  • Patent number: 6625835
    Abstract: A cascaded disk scrubbing system and method are provided. The cascaded disk scrubbing system includes an array of rows of brush pairs. Each row includes a plurality of counter-rotating brush pairs that are arranged horizontally and longitudinally, and configured to receive and process a disk in a vertical orientation through disk preparation zones defined by each pair of brushes. Below and between the pairs of brushes is a track that is configured to apply a rotation to the disk and to transition the disk in a vertical orientation through the brush pairs. Nozzles dispense fluids on and over the brush pairs, and the brush pairs are configured such that fluids are dispensed through the brush pairs. Nozzles dispense a curtain of fluid between each disk preparation zone, and the cascaded disk scrubbing system is configured to progress from dirtiest to cleanest as the disk transitions through each disk preparation zone.

  • Patent number: 6588043
    Abstract: A cascaded wafer scrubbing system and method are provided. The cascaded wafer scrubbing system includes an array of rows of brush pairs. Each row includes a plurality of counter-rotating brush pairs that are arranged horizontally and longitudinally, and configured to receive and process a wafer in a vertical orientation through wafer preparation zones defined by each pair of brushes. Below and between the pairs of brushes is a track that is configured to apply a rotation to the wafer and to transition the wafer in a vertical orientation through the brush pairs. Nozzles dispense fluids on and over the brush pairs, and the brush pairs are configured such that fluids are dispensed through the brush pairs. Nozzles dispense a curtain of fluid between each wafer preparation zone, and the cascaded wafer scrubbing system is configured to progress from dirtiest to cleanest as the wafer transitions through each wafer preparation zone.

  • Publication number: 20030000102
    Abstract: Liquid is removed from wafers for drying a wafer that has been wet in a liquid bath. The wafer and the bath are separated at a controlled rate as the wafer is positioned in a gas-filled volume. The controlled rate is generally not less than the maximum rate at which a meniscus will form between the liquid bath and the surface of the wafer when the liquid bath and the wafer are separated. The gas-filled volume is defined by a hot chamber that continuously transfers thermal energy to the wafer in the gas-filled volume. Hot gas directed into the volume and across the wafer and out of the volume continuously transfers thermal energy to the wafer.

  • Patent number: 6477786
    Abstract: Liquid is removed from batches of substrates by apparatus and methods for drying substrates that have been wet in an elongated liquid bath. The substrates are moved relative to the bath and an elongated gas-filled volume at rates of movement selected according to the location of the batches of substrates in the bath or the volume. As an example, the substrates and the bath are separated at a controlled rate to form a thin layer of liquid on each substrate as each substrate enters the gas-filled volume. The gas-filled volume is defined by an elongated hot chamber and hot gas directed into the volume and across the substrates and out of the volume continuously transfers thermal energy to the substrates . The flow rate of the gas into the volume is related to introduction of the substrates into the bath to avoid disturbing the liquid in the bath.

  • Patent number: 6446355
    Abstract: Liquid is removed from disks by apparatus and methods for drying a disk that has been wet in a liquid bath. The disk and the bath are separated at a controlled rate to form a monolayer of liquid on the disk as the disk is positioned in a gas-filled volume. The separation may be by moving the disk out of the liquid bath, and the controlled rate is generally not less than the maximum rate at which a meniscus will form between the liquid bath and the surface of the disk when the liquid bath and the disk are separated. The gas-filled volume is defined by a hot chamber that continuously transfers thermal energy to the disk in the gas-filled volume. Hot gas directed into the volume and across the disk and out of the volume continuously transfers thermal energy to the disk. The directing of the gas out of the volume is independent of the separation of the bath and the disk.
