    • A security device for a HDMI connector having a HDMI connector head provided on an electronic device having a HDMI socket. The security device includes a locking device including a locking head and a plurality of locker arms extended from two sides of the locking head respectively to define a locker channel for detachably receiving the HDMI connector head. Each of the locker arms has a plurality of engaging teeth formed therealong, wherein the locking device is arranged to operate between a locking mode and a releasing mode, wherein in the locking mode, the locker arms are inwardly pressed to bias against the HDMI connector head when the HDMI connector is plugged into the HDMI socket, wherein in the releasing mode, the locker arms are relieved from the pressing force so as to allow the HDMI connector head to be freely detached from the HDMI socket.
    • 一种用于HDMI连接器的安全装置,其具有设置在具有HDMI插座的电子设备上的HDMI连接头。 安全装置包括锁定装置,其包括锁定头和从锁定头的两侧延伸的多个锁定臂,以限定用于可拆卸地接收HDMI连接器头的锁定通道。 每个锁定臂具有沿其形成的多个啮合齿,其中锁定装置设置成在锁定模式和释放模式之间操作,其中在锁定模式下,锁定臂被向内按压以偏压HDMI连接头 当HDMI连接器插入HDMI插座时,其中在释放模式中,锁定臂从按压力中解除出来,以使HDMI连接器头能够从HDMI插座自由地分离。

    • An optical communication system may include a light transmission unit transmitting a light beam having a first polarization, a quarter waveplate to receive the light beam and to modify the light beam to have a second polarization, and a retroreflector to receive the light beam from the quarter waveplate and reflect the light beam to the quarter waveplate, which modifies the light beam to have a third polarization. The optical communication system may also include a half waveplate to modify the first polarization such that the first polarization is about 90 degrees rotated compared to the third polarization, and a polarizer to pass the light beam having the third polarization and to block most of the light beam having the first polarization.
    • 光通信系统可以包括透光单元,透光单元透射具有第一偏振的光束,四分之一波片以接收光束并修改光束以具有第二偏振;以及后向反射器,用于接收来自四分之一的光束 波片并将光束反射到四分之一波片,其将光束修改为具有第三偏振。 光通信系统还可以包括半波片,以修改第一偏振,使得第一偏振与第三偏振相比旋转大约90度;以及偏振器,以通过具有第三偏振的光束并阻止大部分光 具有第一极化的光束。

    • A method of treating wood chips or saw dust with an enzyme formulation, prior to refining, in order to reduce the total extractives content of the wood chips or sawdust and to modify the wood structure is described herein. The wood chips or sawdust are treated with one or more enzymes such as lipases, esterases, pectinases, cellulases, laccases, hemicellulases and combinations thereof. The enzyme formulation can be applied to the surface of the wood chips or sawdust, e.g. by spraying, or can be impregnated into the wood chips. The enzyme formulation can further comprise one or more surface active agents which can enhance the effectiveness of the enzyme treatment by improving the diffusion or impregnation of the enzymes into the wood chips. The enzyme-based treatment can be applied at any of several different locations prior to the pulping process including chip piles, chip conveyors, chip silos, chips washers, chip washer water stream, impregnation liquor, or during chip storage. The enzyme-based treatment is quick and easy to apply in most commercial mill operations. The enzyme-based treatment is effective at temperatures from about 20° C. to about 100° C., preferably from about 35° C. to about 70° C. The wood chips or saw dust can be treated for a period of time from about 0.10 to about 200 hours, more preferably from about 10 to about 72 hours. The addition of the enzyme formulation into the wood chip or sawdust pile increases the concentration of pitch-degrading enzymes on the chip or dust surfaces which can significantly accelerate the degradation of pitch components inside the chips or sawdust. Decreasing the total extractives content of the wood chips and modifying the structure of the wood chips or sawdust leads to a decrease in the apparent pitch content during pulping and in reduced energy requirements, increased paper strength, improved paper machine runability, and lower costs associated with paper manufacturing.
