  • Patent number: 10719970
    Abstract: One disclosed embodiment includes a method of scheduling graphics commands for processing. A plurality of micro-commands is generated based on one or more graphics commands obtained from a central processing unit. The dependency between the one or more graphics commands is then determined and an execution graph is generated based on the determined dependency. Each micro-command in the execution graph is connected by an edge to the other micro-commands that it depends on. A wait count is defined for each micro-command of the execution graph, where the wait count indicates the number of micro-commands that the each particular micro-command depends on. One or more micro-commands with a wait count of zero are transmitted to a ready queue for processing.

  • Patent number: 10612832
    Abstract: A refrigerator includes a storage chamber, an evaporator configured to cool the storage chamber, and an air passage through which cold air generated by the evaporator flows. The air passage includes a blower fan configured to blow the cold air to the storage chamber, and a trap part in which warm air generated by a defrosting operation stays, such that warm air generated by the defrosting operation is prevented from being introduced into the inner space of the refrigerator through the air passage. The refrigerator reduces the defrosting operation time, efficiently prevents increase of the inner temperature of the refrigerator due to warm air during the defrosting operation, reduces a temperature difference in inner temperature of the refrigerator, and prevents food stored in the refrigerator from being rotten due to a temperature change.

  • Patent number: 10614940
    Abstract: A superconducting magnet device with which device breakage caused by a quench can be avoided while helium consumption is reduced. A sheet-like convection-preventing member is disposed at least either above or below a heat transfer member transferring to gaseous helium heat transferred from the outside, so as to cover a helium gas release tube for the gaseous helium, and thus heat exchange performance during transportation is improved. In the case where the quench occurs, the convection-preventing member is lifted upward in the release tube, thereby ensuring to provide a flow path for the gaseous helium and avoiding excessive increase of the internal pressure.
