A method of communication between two agents, at least one of which is a mobile vehicle, where a first agent includes at least one sensor and a second agent includes a second sensor. The second agent sends to the first agent, via a radio link, features and control parameters of the second sensor necessary to directly query the second sensor. The first agent sends to the second sensor a request for data selected by the first agent on the basis of a selection criterion dependent on the features of the second sensor, the request generated using the control parameters of the second sensor. The second agent sends to the first agent the second sensor's data requested with said data request. Several agents adapted to implement the method are also described.

System and method of communication between a vehicle and an agent

A method for transmitting electromagnetic signals by a vehicle moving towards a target device including a communication system provided with a radiating system that receives and transmits electromagnetic signals, performs an alignment step with the target device to establish a first communication direction with the target device, communicates with the target device by orienting the radiating system to receive and transmit data along the first communication direction, and performs a subsequent phase for maintaining the alignment with the target device to determine a future position and an orientation of the radiating system with a sensor being operatively connected to an electronic control unit of the vehicle configured to implement control and/or driving assistance functions of the vehicle based on information received from the sensor, and ultimately orientates the electromagnetic signals emitted by the radiating system on the basis of the determined direction of communication.

Method and system for pointing electromagnetic signals emitted by moving devices

It is described a modulator apparatus () comprising: an input terminal () structured to receive an analog electrical signal (x(t)) having an information content to be transmitted; a loop filter structured to receive an error signal (&#x3b5;(t) and provide a filtered signal (s(t)), the loop filter being configured to minimize said error signal (&#x3b5;(t)); a modulator device () configured to module the filtered signal (s(t)) and provide a Pulse Width Modulated, PWM, signal (y(t)) to be transmitted including a plurality of pulses having corresponding widths correlated to non-quantized amplitudes of the filtered signal (s(t)); a first pulse width demodulator () configured to receive the PWM, signal (y(t)) and provide a demodulated signal (&#x15d;(t)) and a difference module () configured to receive the analog electrical signal (x(t)) and the demodulated signal (&#x15d;(t)) and provide the error signal (&#x3b5;(t)).

Analog signal width modulator apparatus with closed loop configuration

An apparatus for transmitting optical signals between a central unit () and at least one remote unit (), said central unit comprising&#x2014;at least one amplified spontaneous emission source () of an optical signal, first means () adapted to polarize the optical signal deriving from the amplified spontaneous emission source in a first polarization plane by forming a first polarized optical signal (POS). The apparatus comprises second means () configured to receive said first polarized optical signal and to polarize it in a second polarization plane, orthogonal to the first plane, by forming in said first means a second optical signal (SOS) which is orthogonally polarized with respect to the first optical signal ().

Apparatus for transmitting optical signals between a central unit and at least one remote unit

A conversion unit configured for downconverting a RF radio signal from a first RF band to a first LF band, and up-converting an electric signal from a second LF band to a second RF band; the LF and RF bands have same bandwidth, while RF bands are centered on central frequencies being higher than the LF central frequencies of the LF bands. The conversion unit selects the copper cable link and the first LF band on which transmitting the downconverted RF signal according to a predetermined criteria between a plurality of RF frequency bands and the copper cable links. Moreover, the conversion unit selects the RF connection and the second RF band on which transmitting the upconverted LF signal according to a predetermined criteria between said plurality of RF connections and a plurality of RF bands.
