    摘要: Methods and apparatus for providing primary transport service discovery information over one or more alternate transports that are not normally associated with the primary transport services. In one embodiment, the primary transport comprises a first wireless interface (e.g., Bluetooth), and the alternate transport comprises a second wireless interface (e.g., WiFi or WiMAX). Service profile information relating to the primary transport is broadcast to other users over the alternate transport in a more efficient and streamlined manner than that available on the primary transport. The other users store this service profile information so that it can be subsequently accessed for service profile discovery of the transmitting device by those other devices, thereby obviating subsequent transfer of the data over any transport (primary or alternate).

    摘要: A digital audio system of an aircraft comprising one or more pieces of audio equipment and one or more pieces of radio equipment providing a reliable side tone to the operators. The audio equipment and the radio equipment have installed in the proximity, respectively, an audio-terminal and a radio-terminal connected to a digital network including digital messages management units and digital signal processors. The digital messages management unit of the audio equipment is provided with a computer program adapted to generate a side tone of an analog audio message issued by the microphone of the audio equipment and to activate/deactivate its sending to the headset of the audio equipment when the audio-terminal receives from the radio-terminal an activation/deactivation command for said side tone.

    摘要: In order to send electromagnetic signals received on one or more first frequency bands, the method applies a transformation to the signals, by performing the following actions: selecting first frequency sub-bands, forming a first set of frequency sub-bands of the first frequency band(s); using organization rules to associate one or more second sets of frequency sub-bands, forming one or more second frequency bands, with each first frequency sub-band of the first set; and using optimization rules to determine frequency translations to transpose the signals received in the first frequency sub-bands into signals sent in the second frequency band(s).
