Abstract: A method and system for frequency matching a resonant cavity is disclosed. Light is received in a resonant cavity having at least a first mirror and a second mirror defining a path along which light is reflected. At least the second mirror is actuatable to vary the length of the path of the resonant cavity. An intensity of the light exiting or reflecting from the resonant cavity is monitored, and an error correction is determined. The second mirror is actuated towards a pose relative to the first mirror at which a frequency of the light is in resonance with the length of the path. In this manner, the resonant cavity is frequency matched to the light to maintain the resonant cavity in resonance.

Abstract: A radial tire (1) for a heavy-duty vehicle, in which the reinforcing elements of each hooping layer (331, 332, 333), forming an angle at most equal to 5° with the circumferential direction, and the reinforcing elements of the transverse reinforcer layers (321, 322, 323), forming an angle of between 10° and 45° with the circumferential direction, are extensible and therefore such that, in their rubberized state extracted from a polymer matrix, their structural elongation As is at least equal to 0.5%, their total elongation at break At is at least equal to 3% and their tensile Young's modulus E is at most equal to 150 GPa.

Abstract: A radial tire (1) for a heavy-duty vehicle, with at least two working layers (321, 322, 323, 324) in which the reinforcing elements form an angle at least equal to 10° and at most equal to 45° with the circumferential direction. The metal reinforcers of all of the crown layers of the crown reinforcement are extensible and therefore have, in their rubberized state extracted from a polymer matrix, a structural elongation As at least equal to 0.5%, a total elongation at break At at least equal to 3% and a tensile Young's modulus E at most equal to 150 GPa. The narrower of the two working layers has an axial width at least equal to 60% of the width of the tread and the wider of the two working layers has an axial width at least equal to 70% of the width of the tread.
