Abstract: In some embodiments, a method is provided. The method includes identifying an incident situation based upon a sensor detecting an abnormal condition. One or more life safety systems are queried to obtain life safety system data. One or more databases, comprising equipment information, chemical information, personnel information, and/or emergency response contingency procedures, are queried to obtain on-site information. The life safety system data and the on-site information are integrated together to generate incident situation information. The incident situation information is displayed through an electronic display.

Abstract: A method of wireless communication locator station to be disposed at specific location includes: detecting rotation angle information of client-based portable device, carried or worn by user, according to specific wireless communication standard between wireless communication locator station and client-based portable device when client-based portable device is within signal range of wireless communication locator station; generating head pose direction estimation according to calculated rotation angle information; and when head pose direction estimation indicates that a user turns face towards wireless communication locator station, sending packet signal from wireless communication locator station to server-based portable device, successfully paired with and security-connected with client-based portable device, so that server-based portable device can transfer packet signal to client-based portable device after receiving packet signal.

Abstract: An earphone device includes an earphone module provided with a first connector, and a wireless transmission module provided with a second connector for mating electrically and removably with the first connector such that the earphone module and the wireless transmission module are interconnected electrically and form a single unit for bi-directional wireless voice transmission with a mobile communications device, such as a personal digital assistant or mobile phone. When removed from the earphone module, the wireless transmission module can be connected electrically to an electronic device, such as a computer or car stereo system, through the second connector so as to provide the electronic device with wireless transmission capability.
