  • Publication number: 20240382235
    Abstract: Devices for treating uterine bleeding. An actuator is configured to receive an input to deploy an intrauterine portion of the device to assume a larger outer profile within the uterus. The actuator may be coupled to a device body and configured to receive a pull input, a push input, or a twist input. The intrauterine portion may include flexible opposing members, rotatable tines, a segmented hook, an adjustable loop, or compressible foam. The intrauterine portion defines a lumen and suction ports configured to draw suction within the uterus. Indicia may be provided on the actuator to indicate an extent by which the intrauterine portion has been deployed within the uterus. An orientation of the actuator may correspond to a direction of deployment of the intrauterine portion. The device may include valves and an auxiliary suction source configured to provide suction with the device decoupled from a vacuum source.

  • Patent number: 10379569
    Abstract: A control knob for an appliance includes an outer control ring, a stationary hub, a rotation modulating mechanism coupled to the outer control ring and engaged with an outer surface of the stationary hub, wherein the outer control ring is rotationally operable about the stationary hub at a first rate, an indicial ring positioned around the stationary hub, wherein the indicial ring engages a portion of the rotation modulating mechanism, wherein rotation of the outer control ring at the first rate causes the rotation modulating mechanism to rotate the indicial ring about the stationary hub at a second rate, the second rate being different than the first rate and an encoder shaft positioned within the stationary hub, wherein an inner gearing mechanism extends between an exterior surface of the encoder shaft and one of the outer control ring and the indicial ring.

  • Patent number: 9675101
    Abstract: A juicing system with a drive mechanism and a juicer assembly, where the juicer assembly includes a main housing defining a cavity. A lid encloses a top portion of the cavity and has an opening therethrough. An auger is disposed within the cavity and has a top portion and a bottom portion. The auger is operably connected at one of the top portion or the bottom portion to the drive mechanism to rotate the auger. A rotatable cutting blade is disposed at the top portion of the auger. The rotatable cutting blade cuts foods inserted into the cavity through the opening. A juicing basket is disposed within the cavity, radially outwardly from the auger. The juicing basket has at least one screen with apertures therethrough of varying sizes. Food is pressed by the auger against the juicing basket to squeeze juice and pulp through the apertures.

  • Patent number: 9556916
    Abstract: A clutch mechanism includes first and second shafts having a drive system disposed therebetween, wherein the first shaft is coupled to a drive mechanism. A fixed clutch plate is disposed on the second shaft and includes a plurality of ramped members disposed thereon. An attachment shaft includes a slip clutch plate disposed on a first end and having a plurality of ramped members adapted to releasably couple with the plurality of ramped members disposed on the fixed clutch plate. The slip clutch plate is operable between engaged and disengaged positions relative to the fixed clutch plate and a biasing mechanism is disposed on the attachment shaft and configured to bias the slip clutch plate towards the engaged position. The biasing mechanism is further configured to be overcome when a torque force of a predetermined load is realized on the attachment shaft.
