  • Patent number: 11960030
    Abstract: The invention relates to the technical field of radar detection, in particular to a device for real-time detection of spectrum from airborne hyperspectral imaging LiDAR and method thereof. The device comprises a laser and a reference module; the reference module comprises a first reflecting mirror and a second reflecting mirror with a given transmittance; the first reflecting mirror and the second reflecting mirror are arranged with a focusing mirror and an optical fiber in sequence therebetween. The laser emits a laser light to the first reflecting mirror with a given transmittance, and the beam of the laser light transmitted through the first reflecting mirror after passing the focusing mirror is used as the reference beam after passing the optical fiber. The invention enables detection of the spectral line of each pulse and improves the precision of reflection spectrum of the ground object measured by the system.

  • Patent number: 10071830
    Abstract: A packaging device includes a supporting base, a zipper opener arrangement and a hole pressing arrangement. The zipper opener arrangement includes a driving unit supported on the supporting base, a first bag opening assembly including a plurality of outer operating members operatively and downwardly extended from the driving unit for selectively clamping the first bag panel, and a second bag opening assembly including a plurality of inner operating members operatively and downwardly extended from the driving unit for selectively clamping the second bag panel. The hole pressing arrangement includes a pressing unit supported by the supporting base, a first securing member supported by the pressing unit, and a second securing member supported by the pressing unit at a position which is spaced apart from the first securing member to form a pressing gap between the first securing member and the second securing member.
