  • Publication number: 20240139900
    Abstract: A chemical mechanical polishing apparatus has a platen to support a polishing pad, a carrier head comprising a rigid housing and configured to hold a surface of a substrate against the polishing pad, a motor to generate relative motion between the platen and the carrier head so as to polish the substrate, an in-situ carrier head monitoring system including a sensor positioned to interact with the housing and to detect vibrational motion of the housing and generate signals based on the detected vibrational motion, and a controller. The controller is configured to generate a value for a carrier head status parameter based on received signals from the in-situ carrier head monitoring system, and change a polishing parameter or generate an alert based on the carrier head status parameter.

  • Publication number: 20240097995
    Abstract: Embodiments of this application disclose a network topology display method and a communication apparatus, to improve availability and a visualization effect of a network management and control system. The method in embodiments of this application includes: A communication apparatus obtains a multi-level subnet topology structure, determines a subnet density of a first network element based on a layout setting of a user for a physical position of a subnet of the first network element in the multi-level subnet topology structure, and then determines a current scale based on a zoom operation performed by the user on a display area; and when a product of the scale and the subnet density is greater than a preset value, the communication apparatus expands the subnet of the first network element.

  • Patent number: 11150658
    Abstract: Systems and methods for operating a HAUCS sensing platform. The methods comprise: autonomous travel by a UAAV to a first location in proximity to a body of water (“BoW”) in accordance with a mission plan; actuating a mechanical device to transition a sensor from a retracted position in which the sensor is adjacent to a UAAV to an extended position in which the sensor resides a given distance from a UAAV; collect, by HAUCS sensing platform and sensor, sensor data concerning a water condition of BoW at different depths; actuating the mechanical device to transition the sensor from the extended position to the retracted position after the sensor data has been collected; causing the sensor data to be processed using a machine learning-based analytical engine to determine whether a water distress condition exists/is predicted to occur; and modifying the mission plan when the water distress condition exists/is predicted to occur.

  • Patent number: 9189041
    Abstract: The present invention provides a method and an apparatus for controlling terminal power. The method includes the following steps of: determining whether a power control level set in the terminal is reached or not when controlling the terminal power; if yes, then adjusting a power of the power control level based on a calibration parameter configured in the terminal within a rated output power range corresponding to the power control level; wherein the calibration parameter is 1 dBm; controlling an output power of the terminal according to the adjusted power. The present invention can further perform an accurate terminal power control for reducing power consumption, conserving resources, and increasing system capacity based on a compatibility with conventional power control.
