Abstract: A portable electrical device includes an upper unit, a lower unit and a connection unit having a first end and a second end opposite with each other. The upper unit is pivoted on the first end of the connection unit with a first pivotal portion having a first elastic member. The lower unit is pivoted on the second end of the connection unit with a second pivotal portion having a second elastic member. Therefore, by releasing the first elastic member and the second elastic member, the connection unit is rotated to leave the lower unit, and the upper unit is rotated to contact with the lower unit.

Abstract: A wireless keyboard base includes a base, a wireless keyboard and a plurality of magnets. The base has a groove to accommodate an edge of an electronic device. The wireless keyboard is disposed on the base and has a wireless communication module to exchange information data with the electronic device. The plurality of magnets are disposed within the groove to magnetically attract the edge of the electronic device.

Abstract: A mobile phone with twin rotational shafts is described. The mobile phone has a front module, a rear module, and a first rotational shaft. The front module further has a display and a second rotational shaft. The rear module further has a set of keys and/or an image sensing unit. The first rotational shaft allows the front module to rotate about 360 degrees on the second module. The second rotational shaft allows the display to rotate about 360 degrees thereon. A rotation direction of the first rotational shaft is about parallel to a picture-taking direction of the image sensing module and perpendicular to a rotation direction of the second rotational shaft. A movement direction of the set of keys is about parallel to the picture-taking direction of the image sensing module.

Abstract: A portable computer. The portable computer includes a main body having a depression. A first input module and a second input module are optionally disposed therein, wherein the first input module can be attached to the depression by a first frame, and the second input module thereto by a second frame.
