  • Publication number: 20240151554
    Abstract: The present disclosure provides a method and an apparatus for quickly and accurately evaluating a trajectory of a projectile such as a satellite launching rocket or a missile by comparing the trajectory with a reference trajectory. The trajectory evaluation method includes: acquiring time series positioning data for a target and predetermined reference trajectory information; and mapping points representing the time series positioning data on a graph into corresponding points on a reference trajectory representing the predetermined reference trajectory information while relocating each mapped point onto a relocatable section taking into account a movable range dependent on a speed of the target, and determining a maximum value of distances moved by the points while the points are mapped and relocated as a similarity between the time series positioning data and the reference trajectory.

  • Publication number: 20230347868
    Abstract: Disclosed are a hybrid electric vehicle and a driving control method therefor, which are capable of switching to a driving mode and performing a kick-down shift more quickly. In particular, the method for controlling the hybrid electric vehicle includes: determining a first motor directly connected to an engine and an available torque in a target gear of each second motors connected to the first motor when a driving mode is changed from an electric vehicle (EV) mode to a hybrid electric vehicle (HEV) mode and a kick-down shift is required simultaneously; and determining operating points of the first motor and the second motor before an actual shift ends, based on the determined available torque and the type of kick-down shift.

  • Patent number: 9429525
    Abstract: An optical module for surface inspection includes a first light source unit that illuminates a substrate with first light produced by a first light source and a first beam splitter that changes the path of the first light, a second light source unit that illuminates the substrate with second light polarized in a first direction, a direction of polarization changing unit that illuminates the substrate with the third light polarized in a second direction perpendicular to the first direction, and a detection unit that detects fourth light which is a product of the first light reflecting from the substrate, fifth light which is a product of the second light scattered from the substrate, and sixth light which is a product of the third light scattered from the substrate. The third light is produced by changing the direction of polarization of the second light reflected from the inspected substrate.
