Abstract: The present disclosure relates to the field of synchronising a radio frequency (RF) communication system based on the repeated transmission of data at the transmitter and the use of a method for the time synchronous averaging of this data at the receiver. The proposed communication technique uses the fact that the data signal is periodically repeated, without requiring the use of synchronisation data external to the data to be communicated. It enables phase and frequency synchronisation to be maintained when the received signals are very noisy, and even when they have a signal-to-noise ratio of less than 1 or even a negative signal-to-noise ratio (in dB). A significant improvement in the processing gain of the method for time synchronous averaging is advantageously achieved.

Abstract: A device for recovering or dampening vibratory energy from a mechanical resonator, comprising: an electrical generator comprising an element for converting mechanical vibration energy into electrical charges coupled to the resonator, the electrical generator periodically transferring a portion of the electrical charges from one terminal of the conversion element to the other; a frequency variation to phase variation conversion device, comprising an injection-locked oscillator of which the free-running oscillation frequency is equal to the resonance frequency of the resonator, and supplying to the electrical generator a control signal of frequency equal to that of the signal outputted by the conversion element and of which the phase shift depends on the difference between the frequency of the signal outputted by the conversion element and the resonance frequency of the resonator.

Abstract: A method for a synthesis of a metal catalyst, including providing at least one metal complex including a metal ion and a non-chelating complexing agent having carbon, the complex having a decomposition temperature, and performing a pyrolysis of the complex at a temperature greater than or equal to a decomposition temperature of the complex, whereby inducing a formation of nanoparticles surrounded by a carbon matrix to form the catalyst. Thanks to the carbon matrix, the catalysts provided herein can be corrosion resistant, self-healing, more cost-effective, and can have higher catalytic activity. The synthesis of the catalyst and its properties can furthermore be improved compared to catalysts formed from a complex including a chelating.

Abstract: A method for converting an initial datum between a colour space of a first colorimetric system and a colour space of a second colorimetric system, the initial datum being formed of at least one element expressed in a colorimetric reference system, the method includes: converting the initial datum into a projected datum, by expressing the at least one element in the colour space of the first colorimetric system; adapting the projected datum into an adapted datum, by expressing the at least one element in the colour space of the second colorimetric system. The colour space of the first colorimetric system and of the second colorimetric system are each a hyperbolic space defined by a hyperbolic metric projective reference system.

Abstract: Methods, apparatuses and systems for radio frequency identification (RFID)-enabled information collection are disclosed, including an enclosure, a collector coupled to the enclosure, an interrogator, a processor, and one or more RFID field sensors, each having an individual identification, disposed within the enclosure. In operation, the interrogator transmits an incident signal to the collector, causing the collector to generate an electromagnetic field within the enclosure. The electromagnetic field is affected by one or more influences. RFID sensors respond to the electromagnetic field by transmitting reflected signals containing the individual identifications of the responding RFID sensors to the interrogator. The interrogator receives the reflected signals, measures one or more returned signal strength indications (“RSSI”) of the reflected signals and sends the RSSI measurements and identification of the responding RFID sensors to the processor to determine one or more facts about the influences. Other embodiments are also described.

Abstract: A photoconductive transducer intended to generate or detect waves in the terahertz frequency domain or in the picosecond pulse domain is provided. The transducer comprises a three-dimensional structure that includes, in this order, a first planar electrode, an array of nano-columns embedded in a layer of resist and a second planar electrode parallel to the first planar electrode. The design of the transducer increases the optical-to-terahertz conversion efficiency by means of photonic and plasmonic resonances and by means of high and homogeneous electric fields. The height of the nano-columns as well as the thickness of the resist range between 100 nanometres and 400 nanometres. The width of the nano-columns is between 100 nanometres and 400 nanometres, the distance between two adjacent nano-columns is between 300 nanometres and 500 nanometres, the nano-columns are made of a III-V semiconductor. The second electrode is transparent, so as to allow the transmission of a laser source towards the photo-absorbing nano-columns.
