Abstract: An unloading type sinking rescue device of a subsea mining vehicle and a use method thereof are provided. The unloading type sinking rescue device includes an assembly support, an unloading system, an ejection system and a control system. The assembly support is box-shaped, fixed to a subsea mining vehicle, and provided with a plurality of enclosed cavities. The unloading system includes a counterweight, a counterweight cable, a counterweight fixing bracket and a counterweight recovery cavity. The ejection system includes an anchor, an ejection cavity, an anchor cable, an anchor recovery shaft, a pulley, a spring and a boosting device. The control system controls the operation of the unloading system and the ejection system. The use method includes: (1) unloading; (2) ejection; (3) recovery of a part of counterweights; (4) recovery of the anchor; and (5) recovery of remaining counterweights.

Abstract: A host device includes a first serial peripheral interface (SPI) and a second SPI to communicate with an embedded multimedia card (eMMC) device. The host device has a mode controller that controls the first SPI to toggle between first transmission and first reception modes for command transmission and response reception, respectively. The mode controller controls the second SPI to toggle between second transmission and second reception modes for data transmission and data reception, respectively.
