Abstract: A multimedia adapter for a vehicle has a chassis, an audio and video input port, an integrated audio and video output port and an electronic control unit (ECU). The chassis has an outer surface. The audio and video input port is mounted on the outer surface of the chassis and is connected electrically to a multimedia device. The integrated audio and video output port is mounted on the outer surface of the chassis, is connected to an integrated audio and video input port of a vehicle multimedia system. The ECU is mounted inside the chassis, is connected electrically between the audio and video input port and the integrated audio and video output port, processes data from a multimedia device and has multiple input ports, multiple output ports and built-in incoming call detection and encode/decode features.

Abstract: The present invention relates to a folding plug which has two bottom slots at center of a base while the bottom slots are extended outward with two receiving slots disposed in parallel. Two shaft supports are interposed in parallel between the bottom slots, and the middle section of the shaft supports is fitted with a dished member. Besides, a locating recess is laterally interposed between the shaft supports. When a cover with a press bar is covered on the base, the dished member of the shaft supports is placed upon the shaft used to connect the prongs. The shaft is clamped between the shaft supports of the base and the press bar of the cover so that the prongs are swiveled between the bottom slots and the receiving slots at different angles. In addition, at least two locating flanges are mounted on the rim of said shaft, and the engagement state of the locating flanges of the shaft with the locating recess is changeable so that the prongs can be located at all prearranged angles for different applications.

Abstract: A case locking arrangement mainly comprising two half casings whose apertures are provided opposite to each other, wherein a flange is disposed around the aperture rim of said half casing, at prearranged position of which a number of engaging seats are provided, and wherein at least one locating post upwards extended is provided on the bottom surface of said half casing, at the end of which a screw hole is disposed, and wherein said half casing has an engaging projection and a connecting seat corresponding to said engaging seat and said locating post, and wherein the connecting seat contains a fish eye hole therein.

Abstract: A mobile phone holder having security and charging functions includes a leather bag, a transmitting circuit and a signal receiver. The leather bag is provided with a button to be attached with a receptacle for receiving electricity from a charging set. An pair of electrical conductors are provided within the bag and are in contact with the button. The transmitting circuit is provided within the bag and is in contacted with the electrical conductors. The transmitting circuit is powered by the battery of the mobile phone via the electrical conductors. The signal receiver is in electrical connecting with the transmitting circuit to announce a beeper when the signal receiver is disenabled while kept silent when the signal receiver is enabled by the transmitting circuit.
