Abstract: In one embodiment, an apparatus comprises a nano-scale spectrum sensor configured to be electromagnetically excitable at a predetermined frequency based on received ambient electromagnetic radiation. The apparatus is also configured to be able to use this excitation of the nano-scale spectrum sensor to thereby determine ambient electromagnetic radiation spectrum usage.

Abstract: An approach is presented for activating a device. The activation platform receives a request to make a device operable, wherein the device is in an inoperable state because one or more components for operating the device are absent from the device. Further, the activation platform, in response to the request, validates an authenticity of the device based, at least in part, on one or more identifiers associated with the device. Then, the activation platform retrieves the components. Then, the activation platform causes, at least in part, transfer of the components to the device to make the device operable.

Abstract: In one or more embodiments described herein, there is provided an apparatus comprising a substrate, and a plurality of carbon nanotubes (semiconducting nano-elements) disposed and fixed with said substrate. The nanotubes are disposed and fixed on said substrate such that they define a carbon nanotube network substantially at the percolation threshold of the network. As the network is at the percolation threshold, this provides for one or more signal paths extending from an input region to an output region. The apparatus is configured to, upon receiving particular input signalling via the input region, provide particular predefined output signalling at the output via the one or more signal paths, the particular output signalling being predefined according to the one or more one signal paths.

Abstract: The invention relates to protection of an optical transmission connection. From the transmitting end of the connection, the same optical signal is transmitted along a first path and a second path to the receiving end, where the power level of the signal received from each path is monitored, and one of the paths is selected as the working path and the signal arriving from the said path is connected to the receiver, whereby the other path remains as a redundancy path. For the transmission connection to preserve an optimum performance also when the power level difference between the paths is varying, that path is at each time selected as the working path, where the received signal is considered at the moment in question to have the higher power level. The selection is always carried out when the power level difference between the signals reaches a predetermined threshold value, irrespective of the power level of the signal received at that time from the working path.
