Abstract: A variable pitch blade holder for use with a gas turbine engine. The variable pitch blade holder is configured to retain a blade and to rotate about a center axis with the blade during operation of the gas turbine engine. The blade holder is adapted to rotate about a pitch change axis to vary a pitch of the blade.

Abstract: A gas turbine engine includes a fan having a plurality of fan blades configured to rotate about a central axis of the gas turbine engine. Each fan blade is configured to pivot about a pivot axis that extends radially away from the central axis to vary a pitch of the fan blade. The fan further includes a counterforce system configured to resist forces that urge the fan blades away from their pitch positions during operation of the gas turbine engine.

Abstract: Methods and apparatuses for headset neckbands and earloops are described. In one example, a neckband for use with a headset is described. The neckband includes a first neckband end for coupling with a left earloop and a second neckband end for coupling with a right earloop. The neckband includes a neckband length along an x-axis between the first neckband end and the second neckband end. The neckband length has a variable height in a y-axis direction.

Abstract: Methods and apparatuses for earloops are described. In one example, an earloop for wearing on an ear of a user head is described. The earloop includes a capsule connector segment for coupling to a headset capsule, and an apex segment having an adaptive apex curvature arranged to rest on an apex of the ear. The earloop further includes a behind-the-ear segment having an adaptive behind-the-ear curvature arranged to curve behind the ear and exert a resilient gripping tension behind the ear, wherein the capsule connector segment is located along the x-axis at a different location than the behind-the-ear segment in both a static non-worn state and a static worn state, and wherein the apex segment is between the capsule connector segment and the behind-the-ear segment.

Abstract: A visual task or status indicator comprises a tube having a riser region extending away from a base and an illumination output region distal to the riser region. The tube has the tube wall comprising an optical diffuser material. A waveguide, such as a polycarbonate strand or other optical fiber or a bundle of optical fibers, is enclosed within and extends through the riser region into the illumination output region of the tube. The waveguide is configured to emit light laterally in the illumination output region. A light source is coupled to the waveguide. The light source can have a plurality of output light modes, including various colors or intensities or patterns of colors and intensities. Control circuitry is connected to the light source to select the output light modes in response to a control signal. A plurality of indicators can be controlled from a central control hub.

Abstract: A blade retainer adapted for use in a gas turbine engine is configured to block axial movement of a blade. The blade retainer includes a first brace, a second brace, and a web that extends between the first brace and the second brace.

Abstract: An adjustable height shower apparatus comprises a rigid framework of fluid conduits to which a plurality of sprayers is attached in an arrangement of sprayers, the fluid conduits defining fluid passageways from a fluid inlet port to the arrangement of sprayers, whereby pressurized water is able to flow from the fluid inlet port to the arrangement of sprayers; and a mounting assembly comprising a mounting component configured for attachment at a fixed position on a wall in a shower stall or bathtub installation, the framework and arrangement of sprayers attached thereto being adjustable and lockable at different desired heights on the mounting component. The arrangement of sprayers may comprise a plurality of sprayers arranged in a circumferential manner along an oval portion of the framework.

Abstract: A shower apparatus includes: a mounting bracket or mounting component; and a rigid component or shower panel. The shower panel includes one or more spray arrangements of sprayers, spray arrays, or spray patterns, and fluid passageways connecting water input to the one or more spray arrangements. The shower apparatus further includes a water flow control assembly for selecting a single flow from a plurality of flows to different combinations of the spray arrangements. The water flow control assembly comprises a plurality of buttons, a constrained strip, and a plurality of valves. A button when selected deflects the constrained strip—which is constrained and capable of deflection at a single location—into a corresponding valve to activate flow through the valve. This deflection straightens a previous deflection, thereby closing the previously open valve.
