  • Patent number: 8416514
    Abstract: Provided are a lens unit, a lens assembly, a camera module, a method of fabricating the camera module and the lens assembly, a method of fabricating an optic member, and an apparatus of fabricating the optic member. The lens unit comprises a lens portion and a supporting portion. The lens portion has a curved surface. The supporting portion extends from the lens portion. The supporting portion comprises a protrusion or a recess. The method of fabricating the optic member comprises injecting a resin composition inside a mold die, pressing the resin composition; and irradiating light onto the resin composition. Due to the pressure, shrinkage of a photo-curable resin composition can be reduced, and thus, the lens unit comprising the protrusion or recess can be easily fabricated.

  • Patent number: 7821458
    Abstract: An apparatus and method for locating a terminal in a broadband wireless communication system are provided. The apparatus for locating the terminal includes a candidate region determiner, a virtual location determiner, and a final location determiner. The candidate region determiner determines a candidate region of the terminal by using tag signal arrival time information of the terminal provided from a plurality of readers. The virtual location determiner determines a virtual location of the terminal in the candidate region in consideration of a propagation delay of the tag signal. The final location determiner predicts a tag signal arrival time from the virtual location and determines the virtual location as the final location if a difference between the predicted tag signal arrival time and a measured tag signal arrival time is less than or equal to a threshold value. The apparatus and method provide a less expensive and less complex locating system.
