  • Publication number: 20200341845
    Abstract: Techniques manage a storage system. Along these lines, a failed storage device is detected among storage devices included in a resource pool of the storage system, and the storage devices belong to a first group and a second group in the resource pool respectively. An extent in the failed storage device assigned for building a stripe in the storage system is determined. A spare reserved extent is selected from respective reserved extents included in respective storage devices among the storage devices based on a mapping relation between the stripe and a plurality of extents in the stripe. The respective reserved extents are shared among the first group and the second group. Data in the extent are rebuilt to the selected spare reserved extent. A reserved storage area can be shared among various storage devices in the resource pool, so as to increase allocatable space in storage devices.

  • Publication number: 20200343810
    Abstract: An automatic dead zone time optimization system in a primary-side regulation flyback power supply CCM mode, comprising a closed loop formed by a control system, consisting of a single output DAC midpoint sampling module, a digital control module, a current detection module, a dead zone time calculation module and a PWM driving module, and a controlled synchronous rectification primary-side regulation flyback converter. By means of a DAC Sampling mechanism, a primary-side current is sampled to calculate a secondary-side average current, so as to obtain a primary-side average current Imid_p and a secondary-side average current Is(tmid) in the case of CCM; a secondary-side current is input into the dead zone time calculation module to obtain a reasonable dead zone time td; and finally, the PWM driving module is jointly controlled by a primary-side regulation loop and the obtained dead zone time td.

  • Publication number: 20200344835
    Abstract: This application provides a communication method, a communications device, and a network device. When a beam failure occurs in a secondary cell of the communications device, the communications device sends a beam failure recovery request to the network device by using a PUCCH or a MAC CE, and determines an active state time of DRX based on a status of the beam failure recovery request. The communications device may also determine a stopping time of an uplink retransmission timer based on a running status of a configured grant timer, where the DRX of the communications device is in an active state when the uplink retransmission timer works; and monitors a PDCCH when the DRX of the communications device is in the active state.

  • Publication number: 20200339116
    Abstract: In response to perceiving a moving object, one or more possible object paths of the moving object are determined based on the prior movement predictions of the moving object, for example, using a machine-learning model, which may be created based on a large amount of driving statistics of different vehicles. For each of the possible object paths, a set of trajectory candidates is generated based on a set of predetermined accelerations. Each of the trajectory candidates corresponds to one of the predetermined accelerations. A trajectory cost is calculated for each of the trajectory candidates using a predetermined cost function. One of the trajectory candidates having the lowest trajectory cost amongst the trajectory candidates is selected. An ADV path is planned to navigate the ADV to avoid collision with the moving object based on the lowest costs of the possible object paths of the moving object.
