  • Publication number: 20260198254
    Abstract: Systems and methods are provided to control operational parameter(s) of a spin-on process based on a localized fluid velocity of a processing liquid dispensed onto a surface of a spinning semiconductor substrate. In the present disclosure, a tracer is introduced within, or incorporated onto a surface of, a processing liquid as the processing liquid is dispensed onto the spinning semiconductor substrate. Movement of the tracer is tracked over time, as the tracer flows along with the processing liquid across the spinning substrate surface, to determine a localized fluid velocity of the processing liquid at one or more radial positions on the substrate surface. The localized fluid velocity is then used to control one or more operational parameters of a spin-on process.

  • Patent number: 12664893
    Abstract: The present teaching relates to method, system, medium, and implementations for sensor calibration. A request is received from an ego vehicle in motion for assistance in collaborative calibration, when the ego vehicle determines that a sensor deployed thereon needs to be calibrated. The request includes at least one of a first position of the ego vehicle and a first configuration of the sensor with respect to the ego vehicle. An assisting vehicle is identified based on the first position, the first configuration, and a second position associated with the assisting vehicle and an assistance plan is generated in response to the request indicative of the assisting vehicle to travel to the ego vehicle to facilitate the calibration of the sensor by collaborating with the moving ego vehicle. Such generated assistance plan is then sent out to initiate the collaborative calibration.

  • Patent number: 12660573
    Abstract: Embodiments of processing systems and methods are provided to control operational parameter(s) of a spin-on process based on a fluid height and/or a fluid velocity of a processing liquid dispensed onto a surface of a spinning semiconductor substrate. The disclosed embodiments determine the fluid height and/or the fluid velocity of the processing liquid by: (a) monitoring an intensity of light, which is transmitted through the processing liquid as the processing liquid flows across the surface of the spinning substrate or leaves the periphery of the spinning substrate, or (b) monitoring how long it takes for the processing liquid to flow from a dispensed location to the periphery of the spinning substrate. Once determined, the fluid velocity is used to control one or more operational parameters of a spin-on process.

    Abstract: In implementation of techniques for generating video from an image based on variable speed, a computing device implements a variable speed system to receive a static digital image displayed in a user interface, an indication of a movement direction, and an indication of a variable rate of speed. The variable speed system generates a digital video based on the static digital image, the digital video having pixels that move in the movement direction at a speed that varies based on the variable rate of speed based on pixels from the static digital image. The variable speed system then displays the digital video in the user interface.

  • Publication number: 20260024457
    Abstract: An adaptive test generation system based on varying mastery levels of the user on educational standards to guide and constrain an AI engine in selecting educational standards for adaptive testing and updating user mastery levels based on real-time responses is disclosed. The method involves receiving a list of eligible standards, the user's knowledge graph, and dependencies between standards. A prompt is generated to direct AI engine in choosing the next educational standard for questioning. The AI engine selects a standard based on current knowledge graph and previous user responses, presents a question, and receives the user's answer. The knowledge graph is updated to reflect user's mastery levels of related standards. The AI engine then selects next standard, considering the updated knowledge graph and interdependencies among standards.

  • Patent number: 12469261
    Abstract: This application is directed to augmenting training images used for generating vehicle driving models. A computer system obtains a first image of a road, identifies within the first image a drivable area of the road, obtains an image of a traffic safety object, and determines a detour path on the drivable area. The computer system determines positions of a plurality of traffic safety objects to be placed adjacent to the detour path, and generates a second image from the first image by adaptively overlaying a respective copy of the image of the traffic safety object at each of the positions of the plurality of traffic safety objects on the drivable area within the first image. The second image is added to a corpus of training images to be used by a machine learning system to generate a model for facilitating driving a vehicle (e.g., at least partial autonomously).

  • Patent number: 12416731
    Abstract: The present teaching relates to method, system, medium, and implementations for sensor calibration. An ego vehicle determines whether a sensor deployed thereon to facilitate autonomous driving needs to be calibrated and sends, if it is determined that the sensor needs to be calibrated, a request for assistance in collaborative calibration of the sensor to a center. The request includes at least a first position of the ego vehicle on the route and a first configuration of the sensor with respect to the ego vehicle. When the ego vehicle receives a calibration assistant package, which includes information associated with a collaborative means present along the route and to be used to assist the ego vehicle to calibrate the sensor, it identifies, based on the information, the collaborative means along the route when the ego vehicle is in a vicinity of the collaborative means in order to capture a target present on the collaborative means to enable calibration of the sensor.

  • Publication number: 20250076757
    Abstract: A method for fabricating a semiconductor device with organometallic based photoresists and commercial extreme ultraviolet photolithography. The method for fabricating a semiconductor device includes applying organometallic based photoresist to a substrate and exposing the organometallic based photoresist to extreme ultraviolet photolithography. The method may include introducing an additive to the organometallic based photoresist to promote at least one of adhesion, passivation, reactivity and cross-linking of components in the organometallic based photoresist. The method may also include exposing the organometallic based photoresist to microwave radiation. The microwave radiation may couple with molecular motions, such as internal rotations, to enhance organometallic based photoresist cluster mobility or reorientations. In addition, microwave radiation may induce charge polarization and eddy currents in materials, resulting in induced electron transport and heating due to resistive losses.
