  • Patent number: 12175174
    Abstract: An apparatus and a method optimize a restraint specification based on a particle swarm optimization algorithm using impact analysis between the restraint specification and passenger injuries. A passenger injury prediction value is generated according to the injury degree of a passenger by sequentially inputting values according to specifications of each design variable included in the injury result data into a particle swarm optimization algorithm. The optimization algorithm is implemented with a plurality of computational layers formed for each detailed configuration in order to search for an optimal specification of a restraint. Information on the optimal specification of the restraint is provided by calculating a comprehensive result indicator using the passenger injury prediction value. Thus, the information on the optimal specification of the restraint can be calculated without repetitive evaluation tests.

  • Publication number: 20240393958
    Abstract: A memory system is included in a host device. The memory system incudes: a volatile memory device that performs self-refresh until the host device turns on duty when detecting that the host device is off duty; a non-volatile memory device; and a processor that controls a read operation or a write operation of the volatile memory device and the nonvolatile memory device. The processor backs up data stored in the volatile memory device to the non-volatile memory device after a first time period elapses from when the host device is off duty. The volatile memory device stops the self-refresh after a second time period elapses from a time point when the data stored in the volatile memory device is backed up to the nonvolatile memory device.
