  • Publication number: 20230195188
    Abstract: Methods and systems for thermal management of hardware resources that may be used to provide computer implemented services are disclosed. The disclosed thermal management method and systems may improve the likelihood of data processing systems providing desired computer implemented services by improving the thermal management of the hardware resources without impairment of storage devices. To improve the likelihood of the computer implemented services being provided, the systems may proactively identify whether storage devices subject to impairment due to dynamic motion are present. If such storage devices are present, then the system may automatically take action to reduce the likelihood of the storage devices being subject to dynamic motion sufficient to impair their operation.

The pull-down seat includes a clamping seat and a non-circular rod body passing through the fixed seat in a non-rotation manner. The non-circular rod body includes an internal thread hole. The adjustment bolt is rotatably fixed on the actuation column. The adjustment bolt includes a thread section penetrating in the internal thread hole. The packing assembly is provided between the adjustment bolt and the actuation column. Therefore, a friction force between the adjustment bolt and the actuation column is increased through the packing assembly, and looseness of the adjustment bolt can be avoided.

  • Patent number: 11371648
    Abstract: A positioning structure for tripod stand for quickly releasing a clamping state, comprising a main tube, upper, middle and lower binding sleeves and three support rods. The binding sleeves are sleeved on the main tube to rotate freely. The middle binding sleeve comprises a sliding slot provided with an upper clamping column, a lower clamping column and a spring. The upper and lower clamping columns are connected with upper and lower pressing keys protruding out of the middle binding sleeve. When the pressing keys are pressed, the spring is compressed and the clamping columns no longer protrude from the upper and lower sides of the middle binding sleeve. The clamping state can be released and the support rods of the binding sleeves can be freely rotated by pressing the binding keys, so that the three support rods can be rotated to a storage position or an unfolding position.
