Abstract: A trajectory prediction method and apparatus, a storage medium, and an electronic device are provided. In embodiments of this disclosure, according to a historical trajectory of a designated target and a historical trajectory of each obstacle, a historical interaction feature between the designated target and each obstacle is determined, and a motion trajectory of the designated target is predicted to obtain an initial predicted trajectory. A future interaction feature between each obstacle and the designated target is then determined according to the initial predicted trajectory and a planned trajectory of each obstacle. According to the future interaction feature, a final predicted trajectory of the designated target is obtained.

Abstract: Systems and methods for measuring a value of constituents in a mixed constituent gas having at least one broad band absorber constituent therein and at least one lock constituent are provided. The system uses a combination of integrated cavity output spectroscopy and cavity ringdown spectroscopy to determine the measurement values of constituents in a cavity of a spectrometer. Cavity ringdown in the presence of the at least one broadband absorber constituent and a reference concentration value are used to determine the constituent measurement values when the spectral width of the laser tuning range is overlapped by the absorption band of the broad band absorber in the cavity.

Abstract: An actuator for an automotive seat that includes two main assemblies: (1) a motor assembly; and (2) a gearbox assembly. The gearbox assembly includes multiple stages of gear reduction and a dividing plate. In some embodiments, the gearbox assembly has a single-lead worm, a worm gear with a right-hand helix tooth direction, and a worm gear with a left-hand helix tooth direction. The worm gears are driven by the single-lead worm. The single-lead worm has two ends, one end has a right-hand tooth helix direction, and the other end has a left hand helix direction.
