Abstract: For improving efficiency of a power device having an exposed surface capable of radiating energy, a shielding layer is disposed in between the exposed surface and a conductive layer. The shielding layer causes at least a portion of the energy to be directed back into the power device, thereby substantially preventing the energy from inducing eddy currents in the conductive layer. The conductive layer is fabricated from a metal foil for compliance with electromagnetic energy leakage regulations.

Abstract: A telephone and a dialing method thereof are disclosed. The telephone, communicating with a telecommunication system, has a storage medium for storing a plurality of dialing information. The dialing method includes the following steps: (a) setting a default time period; (b) setting an identification information corresponding to a first dialing information and a second dialing information in the plurality of the dialing information; (c) selecting the first dialing information to operate a first dialing process; (d) proceeding to step (f) when a first response from the telecommunication system responding to the first dialing process; (e) proceeding to step (f) when a first waiting time of the first dialing process exceeding the default time period; and (f) determining whether to select the second dialing information for dialing process.

Abstract: A load applying device includes a rotary member rotatably supported on a base with a spindle, and a magnetic device adjustable concentrically relative to the rotary member, to adjust and to apply a retarding force against the rotary member. A lever may support the magnetic device, and has a curvature corresponding to that of the rotary member. The base includes a casing having two grooves for slidably receiving fasteners which may be threaded to the lever, for guiding the lever to move relative to the casing and the rotary member. Two blocks are engaged with the lever, and a moving device may move the blocks toward and away from each other, to adjust the lever relative to the rotary member.

Abstract: A multi-band antenna (1) used in an electronic device and formed of a metallic sheet by defining holes therein, including a first radiating portion (30), a second radiating portion (31), a third radiating portion (32), a ground portion (2), and a coaxial transmission line (4). The first radiating portion, the ground portion and the coaxial transmission line cooperatively form a loop antenna operated at a higher frequency band of about 5.15-5.875 GHz. The second radiating portion, the ground portion and the coaxial transmission line cooperatively form a first inverted-F antenna operated at another higher frequency band of about 5.725-5.875 GHz. The third radiating portion, the ground portion and the coaxial transmission line cooperatively form a second inverted-F antenna operated at a lower frequency band of about 2.4-2.5 GHz.
