Abstract: A mobile phone search device and search method thereof. Firstly, utilize a portable mobile phone detector to transmit a base station signal in its transmission region, and this region covers at least one or more mobile phones. Then, when the mobile phone detects the base station signal, it can log onto a network to establish communication channel with the portable mobile phone detector, and that can assign a communication number to each of the mobile phones, for the mobile phones to communicate in voice signal or short message with the portable mobile phone detector on its own initiative. Through applications of the mobile phone search device and search method thereof, the mobile phone having its communication with the base station disrupted can be detected and communication re-established swiftly, thus locating said trapped person and raising rescue efficiency significantly.

Abstract: A connector for easily connecting a peripheral to a mobile telephone that allows the peripheral to be oriented in at least two directions. The connector comprises a phone-side connector attached to a mobile telephone and a peripheral-side connector attached to the peripheral. The phone-side connector comprises a plurality of contacts which are duplicated adjacent to the contacts but in a reverse order. The peripheral-side connector also comprises a plurality of mating contacts which are duplicated adjacent to the contacts but in a reverse order. In this way, the phone-side connector and the peripheral-side connector can properly mate regardless of the orientation, either facing towards or away from the mobile phone user.
