Abstract: A radiation shielding apparatus for a wireless communication device operable in at least two cellular frequency spectrums includes a multi-band antenna operably associated with an electromagnetic radiation shield that extends along a length of the antenna. The shield partially surrounds the antenna and is disposed between a user of the communication device and the antenna.

Abstract: A shredder blade set with low resistance combines pressed blades and polished blades in various ways to form a shredder blade set. The shredder blade set has an appropriate friction for solving the problems with tilted or wrinkled paper due to insufficient friction or power waste due to large friction.
Abstract translation: 具有低阻力的粉碎刀片组合压制刀片和抛光刀片以各种方式形成粉碎刀片组。 粉碎刀片组具有适当的摩擦力，用于解决由于摩擦力大而引起摩擦不足或动力浪费造成的倾斜或起皱纸张的问题。
