Embodiments of the present disclosure are directed towards techniques and configurations for thermal management of an integrated circuit assembly using a jumping-drops vapor chamber. The first and second address regions are then mapped so that a first physical address region corresponding to a predetermined part of the first address region and a second physical address region corresponding to a predetermined part of the second address region access the same address region. The motor drive system includes a power supplying device to output direct current voltage, and a voltage step-up device to increase, at a certain step-up ratio, the direct current voltage which is output from the power supplying device. A pivotal linkage pendulum system may be coupled to the crank system. In other embodiments, the trusted antivirus tool may scan the computing device and remove any viruses detected by the trusted antivirus tool.
