Abstract: Structures and methods for conserving power in wireless, multi-homed communication devices includes powering down unused network communication devices while leaving an active or most desired network communication device active. A prioritized list of the available network communication devices, based on user preferences, is used to activate the desired network communication device(s) and power down the other network communication devices.

Abstract: A connection manager (112) of a communication device (103). The connection manager registers with a device driver (109) associated with a network interface (106, 228), which monitors the communication device for network access data from a third party connection manager (118). After detecting network access data, the device driver notifies the connection manager. Depending on one or more policies or user input received from a user interface (115), the connection manager may unregister with the device driver, disable the third party connection manager, or notify the user via the user interface that manual intervention may be required. The connection manager may prevent conflicts between itself and the third party connection manager.

Abstract: A device uses bluetooth techniques to communicate with electronic devices in an airplane. During take off or landing, the radio on board the airplane operates in bluetooth mode to send a global poll to all devices requesting that they respond. If a device responds, then it indicates that the device is on at an unauthorized time. This informs the crew that they should try to find the unauthorized device and turn it off.
