Abstract: A multimedia audio dock is provided to support a portable electronic device so that the portable electronic device can stand on a plane. The multimedia audio dock includes two retractable arms formed by a plurality of sleeved-through tubes so that the length of the two retractable arms can be varied to a predetermined length. A biaxial hinge providing two rotational axes is connected to the two retractable arms, so that the two retractable arms may rotate relative to each other about two rotational axes. Two speakers provided respectively at the ends of the two retractable arms opposite to the ends connected to the biaxial hinge. The speakers receive the audio signals and output sound. And the electronic device is held between the two speakers moved by the two retractable arms, so that the portable electronic device can stand on the plane.

Abstract: A portable electronic device includes a body, a signal transmitter/receiver. The body includes a display which has a first display mode and a second display mode. The signal transmitter/receiver has a ball spiral, a first ball and a second ball. The signal transmitter/receiver is pivotally connected to the body of the portable electronic device. The signal transmitter/receiver can be rotated around a rotation axis defined by the first ball and the ball spiral to a first signal receiving position corresponding to the first display mode, and can be rotated around a rotation axis defined by the second ball and the ball spiral to a second signal receiving position corresponding to the second display mode. Therefore, signals can be better transmitted or received when the display is in a given display mode.

Abstract: An electrical apparatus with a rotating stage set pivotally connecting to a host shell, and an antenna module pivotally connecting to the rotating stage set is provided. The rotating stage set rotates about the X-axis, and the antenna module rotates about the Y-axis with respect to the host shell. In addition, the electrical apparatus can thus obtain the best signal receiving and transmitting efficiency by adjusting the antenna module to the best receiving and transmitting position and angle.

Abstract: A PDA for connecting with selectively installed communications modules. Both communications modules have their own corresponding connector and fixing device connected electrically and mechanically between the PDA and the communications module. With the above modules, the PDA becomes a tool with extendable specific communication functions. The communications module can be either a GPS or a cellular phone handset's communications module. They can be attached to a PDA to provide additional communication functions.

Abstract: A PDA for connecting with a digital image capture module. The PDA includes a connecting device and attaching devices that form electrical and mechanical connections between the PDA and the digital image capture module, which includes corresponding devices. As described, the PDA becomes a tool with extended digital image capturing functions.
