Abstract: A transmitting device includes a transmitting chain, a configurable power amplifier device and an impedance tuning circuit. The transmitting chain is arranged to generate a radio frequency signal. The configurable power amplifier device is arranged to support at least a first power amplifier configuration and a second power amplifier configuration, wherein the configurable power amplifier device employs the first power amplifier configuration to receive and amplify the radio frequency signal when the transmitting device is operated in a first operation mode, and employs the second power amplifier configuration to receive and amplify the radio frequency signal when the transmitting device is operated in a second operation mode. The impedance tuning circuit is arranged to adjust an output impedance of the configurable power amplifier device employing the second power amplifier configuration when the transmitting device is operated in the second operation mode.

Abstract: An emergency mode is provided in a portable electronic device for locating a survivor in a disaster. The device includes a wireless antenna to transmit and receive wireless signals; a memory to store one or more identifiers; a user interface to receive a command that enables the emergency mode. The device also includes one or more processors, which, in response to the command, detect via the wireless receiver a predetermined identifier that matches a stored identifier identifying a sender of the predetermined identifier as a trusted node. When the predetermined identifier and a timing measurement frame are received from the trusted node, the device sends a response to the trusted node to indicate its presence.
