    • A source device determines content rights for encrypted content in the first encoding standard using a first rights data file. The source device creates a second rights data file for transcoded content in the second encoding standard. The source device performs a key management operation including communicating a decryption key for the encrypted content in the first encoding standard to a transcoder. The source device transfers the encrypted content in the first encoding standard to the transcoder. The transcoder decrypts the encrypted content, transcodes the content from the first encoding standard to the content in the second encoding standard, and re-encrypts the content in the second encoding standard using a second encryption key. The transcoder then transfers the encrypted content in the second encoding standard to an indicated device.
    • 源设备使用第一版权数据文件来确定第一编码标准中的加密内容的内容权限。 源设备为第二编码标准中的经转码的内容创建第二版权数据文件。 源设备执行密钥管理操作,包括将第一编码标准中的加密内容的解密密钥传送到代码转换器。 源设备将第一编码标准中的加密内容传送到代码转换器。 代码转换器解密加密的内容,将内容从第一编码标准转码为第二编码标准中的内容,并且使用第二加密密钥对第二编码标准中的内容重新加密。 然后,代码转换器将第二编码标准中的加密内容传送到指定的设备。

    • The present invention discloses an apparatus for removing unwanted plants from a specific area of soil. The invention is comprised of a blade that is adapted to penetrate the surface of the soil and moving substantially parallel to the surface thereof. Proper movement of the blade is assisted by fins positioned on the sides of the blade, and act similarly to the rudder of a boat. The blade has a support member that has one end attached to the blade and the other end is capable of receiving a handle. The handle is configured in an arcuate shape to better facilitate grasping and holding by the user. This combination allows the user to grasp the handle, one hand on each side of the support member and blade, and push the invention forward undercutting the undesirable plant roots, thereby killing them. Minimal disruption of the soil is experienced, thereby optimizing the efficiency of work done by the user.
    • 本发明公开了一种从土壤的特定区域去除不想要的植物的装置。 本发明包括适于穿透土壤表面并基本平行于其表面移动的叶片。 叶片的正确运动由位于叶片侧面的翅片辅助,并且与船的方向舵相似。 叶片具有一个支撑构件,其具有连接到叶片的一端,另一端能够接收手柄。 手柄被配置成弓形形状,以更好地方便使用者的握持。 这种组合允许用户在支撑构件和叶片的每一侧上握住手柄,并且将本发明向前推动,从而切割不期望的植物根部,从而杀死它们。 经历了最小的土壤破坏,从而优化了用户完成的工作效率。

    • In a packaging machine of the type in which a "tin-tie" strip is affixed to a bag to allow repeated reclosures of the bag, a machine for cutting a continuous strip of tin-tie material into predetermined lengths and feeding the cut lengths into a bonding station where they are adhesively bonded to the bag proximate its top opening. The machine comprises a frame supporting a pair of electromagnetic clutches, one for selectively coupling a continuously driven shaft to an output shaft to which a tin-tie strip feedwheel is attached and the other for selectively coupling a continuously driven shaft to an output shaft to which a rotary cutting head is secured. Passage of a bag past a sensor triggers the two clutches which function to withdraw a predetermined length of tin-tie material from a supply reel and to sever the strip while feeding the cut length to the bonding station at the same speed as the bag is moving.
    • 在这种类型的包装机中,其中将“锡带”带固定到袋子上以允许袋重复重新闭合的机器,用于将连续带状锡带材料切割成预定长度并将切割长度送入 粘合站,其粘合到靠近其顶部开口处的袋附近。 该机器包括支撑一对电磁离合器的框架,一个用于选择性地将连续从动轴连接到连接有锡带输送轮的输出轴,另一个用于选择性地将连续从动轴连接到输出轴, 固定旋转切割头。 通过传感器的袋子通过触发两个离合器,其功能是从供带盘上取出预定长度的锡束材料,并且以与袋移动相同的速度将切割长度供给到粘结站的同时切断条带 。
