  • Patent number: 11937103
    Abstract: State information of a radio-based application, used to process messages of the application, is made accessible from a first compute instance and a second compute instance at a virtualization server. The first instance is assigned to process a first portion of a workload of the application, including a message which comprises a result of a network function executed at a network function accelerator of the server. In response to determining that a condition for migrating workload from the first compute instance has been met, an additional message of the first portion is directed to the second compute instance. The second compute instance processes the additional message using the state information.

  • Patent number: 11888701
    Abstract: Disclosed are various embodiments for improving self-healing and resiliency of radio-based networks through the use of a community model. In one embodiment, a community model graph representing a radio-based network is generated. Individual nodes of the community model graph correspond to one or more network functions of the radio-based network. Individual edges of the community model graph correspond to a respective network connection between the network function(s) of the radio-based network. The individual edges are assigned a respective measure of relative importance. An adverse health event is detected that impacts a plurality of network connections between network functions in the radio-based network. Self-healing activities for the network connections are prioritized based at least in part on the respective measures of relative importance corresponding to individual network connections.

  • Publication number: 20240023382
    Abstract: An organic light-emitting diode (OLED) display may have an array of organic light-emitting diode pixels that each have OLED layers interposed between a cathode and an anode. Voltage may be applied to the anode of each pixel to control the magnitude of emitted light. The conductivity of the OLED layers may allow leakage current to pass between neighboring anodes in the display. To reduce leakage current and the accompanying cross-talk in a display, a cutting structure may disrupt continuity of the OLED layers. The cutting structure may have two undercuts to disrupt continuity of at least some of the OLED layers. The cutting structure may include a conductive portion that provides a cathode voltage to a cathode layer for the OLED pixels.

  • Publication number: 20230333168
    Abstract: A method and a device for battery detection are provided. In the method, multiple characteristic values measured from a battery during operation of the battery are captured via a data capturing device to form a characteristic curve. Curve fitting is performed on the characteristic curve to obtain a curve error. According to the magnitude of the curve error, it is determined whether the battery is normal. When the determination result is abnormal, a step-curvature radius analysis is performed on the characteristic curve to determine whether the battery is normal.
