Abstract:
A node detection system includes an array of nodes (510), wherein each node of the array of nodes (510) has at least at least two, three or four directional antennas (530) configured to have antenna beams in as many directions. The range of each antenna is limited to reach a neighboring operational node of the array of nodes (510) for transmission of a message to the neighboring operational node. A controller (550) is configured to receive messages from the array of nodes (510) and determine the location of each node based on the messages.

Abstract:
A method is provided of changing between modes in a device. The method comprises changing the mode of the device in response to a change in the temperature of a first point of the device relative to the temperature of a second point of the device. Such a change in temperature may be created, for example, by the body heat from a user picking the device up. In certain embodiments, this allows the device to be switched between a completely powered-down mode to a powered-on mode without consuming any power in the powered-down mode. Further, the method provides a convenient and user- friendly way of operating the device.
