  • Patent number: 11408323
    Abstract: An exhaust manifold heat dissipation cover coupling device for thermal stress and vibration deflection is proposed. The device has a function of preventing wear of a heat dissipation cover to couple an exhaust manifold heat dissipation cover, the device being able to improve the durability of various parts including a heat dissipation cover by attenuating multi-directional vibration that is transmitted from an exhaust manifold when the heat dissipation cover is installed outside the exhaust manifold, being able to prevent damage to parts due to thermal stress by flexibly coping with thermal deformation such as thermal contraction or thermal expansion even if the thermal deformation is generated by high-temperature heat transmitted from the exhaust manifold, and being able to prevent frictional damage of the heat dissipation cover due to friction by a component that slides to attenuate vibration.

  • Patent number: 11326884
    Abstract: A disk resonator is pumped by counterpropagating pump signals to produce corresponding counterpropagating Brillouin laser signals. The pump laser optical frequencies are separated by a frequency offset ??P but excite the same nominal resonator optical mode; the Brillouin laser optical frequencies are separated by a beat frequency ??L with 0<??L<??P. A photodetector receives the Brillouin laser signals and produces an electrical signal at the beat frequency ??L. The frequency offset ??P can be large so enough to prevent locking of the Brillouin laser signals onto a common Brillouin laser frequency. A signal processing system derives from the beat frequency ??L an estimated angular velocity component of the disk optical resonator about an axis substantially perpendicular to the disk optical resonator.
