  • Publication number: 20150153776
    Abstract: A screen protection device for protecting a display screen of an electronic apparatus includes: a tempered glass sheet, a mask layer, an optical clear adhesive layer, and an adhesive layer. The mask layer is positioned on the tempered glass sheet and defines a transparent region for the screen protection device. The optical clear adhesive layer is positioned on the tempered glass sheet and covers the transparent region, but does not cover the mask layer. The adhesive layer is positioned on the mask layer and the optical clear adhesive layer, and is utilized for detachably attaching to the display screen of the electronic apparatus. A thickness of the optical clear adhesive layer is at least 80% of a thickness of the mask layer.

  • Publication number: 20150153853
    Abstract: A screen protection device for protecting a display screen of an electronic apparatus includes: a plastic film, a mask layer, a UV cured layer, and an adhesive layer. The mask layer is positioned on the plastic film and defines a transparent region for the screen protection device. The UV cured layer is positioned on the plastic film and covers the transparent region, but does not cover the mask layer. The adhesive layer is positioned on the mask layer and the UV cured layer, and is utilized for detachably attaching to the display screen of the electronic apparatus. A thickness of the UV cured layer is at least 80% of a thickness of the mask layer.

  • Publication number: 20150153775
    Abstract: A screen protection device for protecting a display screen of an electronic apparatus includes: a tempered glass sheet, a mask layer, an adhesive layer, and a two-part Epoxy glue layer. The mask layer is positioned on the tempered glass sheet and defines a transparent region for the screen protection device. The adhesive layer is positioned on at least a portion of the mask layer and surrounds the transparent region, and is utilized for detachably attaching to a target region on a surface of the hand-held electronic apparatus. The two-part Epoxy glue layer is positioned on the tempered glass sheet and covers the transparent region. When the adhesive layer is attached to the target region, the two-part Epoxy glue layer is positioned between the tempered glass sheet and the display screen, directly contacts with the display screen, and detachably attaches to the display screen.

  • Patent number: 9008506
    Abstract: A fiber network events measurement apparatus has a laser module alternately generating a pulse signal detecting beam and an FMCW detecting beam. The beams are sent to the fiber network route through a directional coupler. A photo detector receives feedback energy of the beams transmitting in the fiber network route and converts the feedback energy into electronic signals. A mixer uses a frequency difference calculation to obtain a comparison result according to an original and a reflected FMCW signal. The electronic signal is converted into a digital signal by an A/D converter. A signal control unit then obtains a compound trace result including information of characteristic trace and event positions. The compound trace result shows a fiber characteristic trace and event position trace for measuring the fiber network routes.

  • Patent number: 8855486
    Abstract: A remotely controlled fiber testing method has the steps of: building a fiber network system including a local fiber station and a remote fiber station; sending a modulated signal to the remote fiber station by the local fiber station; demodulating the modulated signal to obtain a control command by the remote fiber station; executing the control command to obtain a testing result by the remote fiber station; modulating the testing result and sending the testing result back to the local fiber station; and demodulating the testing result by the local fiber station. Only one technician appointed to the local fiber station is sufficient to do the testing action. Therefore, the personnel cost is effectively reduced.

  • Patent number: 8837937
    Abstract: A detecting device that detects insertion loss of fiber route and return loss of individual events in an optical fiber network based on signals from dual paths to obtain various kinds of reference information of the optical fiber network. When the first path is selected, a detection signal produced using frequency modulated continuous wave (FMCW) technique is output to the optical fiber network. A return signal of the detection signal is used to analyze the position and return loss of various events in the optical fiber network. When the second path is selected, a common detection light is output to the optical fiber network. Based on the return signal of the common detection light, the insertion loss and total return loss of the entire network are obtained.
