Abstract: Un courant gazeux à concentration en oxygène réduite par rapport à l'air ambiant est utilisé pour vaporiser un combustible liquide ou un gaz d'hydrocarbure liquéfié ou est mélangé à un gaz vaporisé, le gaz combustible vaporisé à teneur en oxygène réduite étant envoyé dans un dispositif de combustion tel qu'une chambre de combustion à prémélange ou à diffusion. De préférence, la teneur en oxygène du courant gazeux est inférieure à l'indice limite d'oxygène. En mélangeant le combustible au courant gazeux à une teneur en oxygène réduite de façon appropriée, on peut éviter l'inflammation spontanée avant le front de flamme. Selon certains modes de mise en oeuvre, le courant à teneur en oxygène réduite est généré depuis un séparateur d'air ou évacué d'un dispositif de combustion.

Patent CA-2506267-A1 (CA)
Title: Multi-subband frequency hopping communication system and method
Inventor: VIGNERON PHILIP
IPC: H04J13/06
Filed: 2005-05-03
Abstract: The invention provides an adaptive frequency hopping spread-spectrum (FHSS) transmission system and method, which efficiently utilizes available transmission bandwidth, whilst providing robustness to jamming techniques in wireless communication systems. The proposed technique operates by transmitting a wide-band signal over multiple, single-carrier, parallel transmission subbands, which may occupy non-contiguous frequency regions. The proposed scheme exhibits significant gain in error rate performance, as compared to a data rate equivalent single-subband system in the presence of signal jamming and/or interference without a reduction in the transmission data rate nor an increase in transmitter power. In addition, the proposed system and method are adaptive and enable more efficient use of the available bandwidth for communicating, thus increasing the overall bandwidth utilization of the system.
