  • Publication number: 20240090604
    Abstract: Various aspects disclosed relate to structure such as a textile, a garment, a garment component, footwear, or a footwear component. The present disclosure includes the structure having a first region having one of more first fibers. An individual first fiber includes co-extruded first and second filaments, the first filament formed of a first thermoplastic polymeric material. Due to expansion or contraction of the one or more first fibers, the first region contracts or expands on a change in relative humidity, relative to an equilibrium state of the first region prior to the change in relative humidity.

  • Patent number: 10162369
    Abstract: A liquid level control module comprising an elongated tubular housing immersible through a surface of a liquid and into a bulk volume of the liquid, and first, second, and third electrical switches, and first and second floats movable along the tubular housing. The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.

  • Patent number: 10082268
    Abstract: A visually observable display comprising a circuit board including at least one illuminator emitting light outwardly from a surface of the board, a light transmissive display window pane operable to receive light at an inner surface and transmit the light through an outer surface, and an insert disposed between the illuminator and the display window pane. The insert comprises an elongated light distributing conduit receiving light from the at least one illuminator at a first location in a direction substantially perpendicular to the display window pane, distributing the light transversely through the light conduit along the inner surface of the display window pane, and redirecting the distributed light outwardly along an outer wall of the conduit and outwardly through the window pane. The display may include multiple light illuminators emitting light outwardly from the board surface and into the light distributing conduit at discrete locations along the conduit.

  • Patent number: 9481991
    Abstract: A macerating apparatus for a toilet in which the problem of jamming the macerator at startup is solved by rapidly detecting the flushing of the toilet and accelerating the macerator before motion-jamming solid objects in the effluent from the toilet can reach the macerator. The macerating apparatus may be comprised of a macerating cutter operatively connected to a motor, and a sensor in communication with the motor. The sensor may detect the flow of effluent from the toilet toward the macerator, the flow of makeup water from the supply tank into the toilet, or the mechanical action of the mechanism used to flush the toilet. The apparatus may include an intake basket having an asymmetric inlet tube and containing the macerating cutter, wherein the asymmetry of the inlet tube provides additional operating clearance between a cutting blade of the macerating cutter and the intake basket.
