  • Medical devices including rotary valve
    Patent number: 11324942
    Abstract: A medical device includes a constant-flow pump configured to pump a fluid through a fluid conduit and a rotary valve fluidically connected to the pump. The rotary valve includes at least one rotatable valve member configured to be operatively connected to and rotate relative to the fluid conduit. The rotatable valve member includes at least one aperture. The rotatable valve member is capable of being positioned in a plurality of positions relative to the conduit. The position of the at least one first aperture of the rotatable valve member controls fluid flow through the rotary valve, and thereby through the conduit.
    Type: Grant

  • Using electromagnetic waves and/or injection to facilitate operation of catalytic converters
    Patent number: 10697339
    Abstract: A system includes an exhaust conduit coupled, at least first end of the exhaust conduit, to an internal combustion; a catalytic converter coupled to a second end of the exhaust conduit; and electromagnetic wave source configured to emit electromagnetic energy; and a wave guide, coupled at a first end to the electromagnetic wave source and at a second end to the exhaust conduit, and extending between the electromagnetic wave source and the exhaust conduit. The electromagnetic wave source is configured to provide the electromagnetic energy, via the wave guide, to exhaust gas traveling through the exhaust conduit.
