Patent number: 11460375Abstract: A specific sound having a higher frequency than an operation sound of an engine is generated in synchronization with timing of a top dead center of a specific cylinder of the engine. Thus, timing of a noise of the engine is estimated by using, for example, a deviation in time between timing of generation of a specific sound and timing at which a noise occurs in the engine, based on a sound collected from around the engine without directly using a signal of a crank angle of the engine.Type: GrantFiled: January 26, 2021Date of Patent: October 4, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Yoshiya Yamashita

Patent number: 11428091Abstract: A gas separator can include an intake section. Splines extend radially from an inner manifold of the intake section and engage an interior surface of an outer housing, thereby isolating openings formed in the splines from longitudinal channels extending through the outer housing. Another gas separator can include an intake section, a discharge section and multiple intermediate sections connected between the intake and discharge sections. A gas separation system can include a completion string including a packer, a downhole pump and a gas separator connected between the packer and the pump. An annulus is formed between the gas separator and a wellbore, an intake section of the gas separator receives formation fluids from below the packer, a discharge section of the gas separator discharges gas and liquids into the annulus, the intake section receives the liquids from the annulus, and the pump receives the liquids from the discharge section.Type: GrantFiled: December 13, 2019Date of Patent: August 30, 2022Assignee: Odessa Separator, Inc.Inventors: Cavin B.
