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 tuner module including a first carrier, a tuner, a second carrier, a tuner connector, a digital modulator, a digital decoder, an analog decoder and a display unit is provided. The tuner is disposed on the first carrier for tuning the frequency to receive a source signal to generate a digital or an analog video signal. The tuner outputs the digital or the analog video signal via the tuner connector. The digital modulator receives the digital video signal via the tuner connector to output a transport stream. The digital decoder controls the display to display frames. The analog decoder receives an analog video signal via the tuner connector to generate a decoded signal. The display unit receives the decoded signal for controlling the display to display frames. The tuner connector, the digital modulator, the digital decoder, the analog decoder and the display unit are disposed on the second carrier.
