Abstract: A safety apparatus is used to be arranged at a movable member of automatic device and is communicatively connected to a controller of the automatic device. The safety apparatus includes a contact detector and a module. The contact detector is for detecting a contact event of the safety apparatus, and outputting a contact signal. The module includes a first input terminal, a second input terminal and an output terminal. The first input terminal is communicatively connected to the contact detector, and is for receiving the contact signal. The second input terminal is communicatively connected to the output terminal, and is capable of communicatively connecting to an output terminal of another safety apparatus. The output terminal is communicatively connected to the first input terminal, and is for outputting an output signal when the first input terminal receives the contact signal.

Abstract: A method and system for detecting and locating trapped people are provided. The method includes the following steps: (a) transmitting a first wireless signal based on a transmission power, and recording the transmission power; (b) when a first mobile device registers to the system for detecting and locating trapped people in response to the first wireless signal, recording identity information of the first mobile device; (c) determining whether the transmission power is a maximum transmission power; (d) if no, increasing the transmission power, and repeating the steps (a) to (d); if yes, calculating a relative location between the first mobile device and the system for detecting and locating trapped people based on the recorded transmission power and the recorded identity information.

Abstract: With the aid of critical conditions including remaining power of a communication module and both an available bandwidth and a credit of utilizing communication functions of said communication module, and by cooperating with available network services of said communication module, a communication network currently appropriates for said communication module to be switched to is determined, for achieving an aim of retrieving network services and taking requirements of users into consideration simultaneously. Moreover, when there are no available network services for the communication module, said communication module enters a sleep state for about less than ten seconds, for preventing said communication module from consuming additional power or from bringing in unnecessary consumption in other aspects, where both the additional power and the unnecessary consumption in other aspects are caused from the fact that the communication module searches for available network services continuously.

Abstract: An application-oriented and intelligent method for switching communication modes of a dual-mode communication module is provided. Whether the application program utilizes location-based service is first confirmed. When the application program utilizes location-based service, said communication module is switched to the first communication mode. Otherwise, evaluation, about which one from both the first communication mode and the second communication mode is more beneficial for a user, is performed on the communication module, according to both an available bandwidth and quality of service provided by a communication mode and to both a power and a credit of utilizing communication functions of the communication module. At last, a result of the evaluation is utilized for determining which communication mode from both the first communication mode and the second communication mode to be utilized by the communication module.
