Abstract: A power coupler for transferring rotary power from a rotary power device to a load device includes a shear thickening fluid (STF) and a chamber that contains the STF. The power coupler further includes a drive shaft housed radially within a drive side section of the chamber and protruding outward from an end of the chamber for coupling to the rotary power device. The power coupler further includes a load shaft housed radially within a load side section of the chamber and protruding outward from another end of the chamber for coupling to the load device. The power coupler further includes a drive turbine housed radially within the drive side section and coupled to the drive shaft. The power coupler further includes a load turbine housed radially within the load side section at a fixed operational distance from the drive turbine and coupled to the load shaft.

Abstract: A head unit system for controlling motion of an object includes a secondary object sensor, shear thickening fluid (STF), and a chamber configured to contain a portion of the STF. The chamber further includes a front channel and a back channel. The head unit system further includes a piston housed at least partially radially within the piston compartment and separating the back channel and the front channel. The piston includes a first piston bypass and a second piston bypasses to control flow of the STF between opposite sides of the piston. The chamber further includes a set of fluid manipulation emitters to control the flow of the STF to cause selection of one of a variety of shear rates for the STF within the chamber.

Abstract: The present disclosure relates to a fluid dispensing device (10), the fluid dispensing device (1) comprising: a housing (10) to accommodate a container (110) filled with a fluid, wherein the housing (10) comprises a sidewall 118) extending along a longitudinal direction (z), —an outlet orifice (3), —a discharge mechanism (130) operable for spray discharging at least one or multiple doses of the fluid via the outlet orifice (3), —a protective cap (12) pivotally supported on or by the housing (10) between an open position and a closed position, wherein when in the closed position the outlet orifice (3) is effectively covered by the protective cap (12), —a mechanical energy storage (50) coupled to the discharge mechanism (130), reversibly transferable between a preloaded state and an unloaded state and configured to store mechanical energy in the preloaded state effective to produce the spray discharging of the fluid, —a biasing mechanism (150) comprising a biasing member (160) operationally coupled to the prote

Abstract: The present disclosure relates to a fluid dispensing device (1) comprising: —a housing (10) to accommodate a container (110) filled a fluid, —a outlet orifice (3), —a discharge mechanism (130) operable for spray discharging multiple doses of the fluid via the outlet orifice (3), —a mechanical energy storage (50) coupled to the discharge mechanism (130), reversibly transferable between a preloaded state and an unloaded state and configured to store mechanical energy in the preloaded state effective to produce the spray discharging of the fluid, —a releasable interlock (70) configured to retain the mechanical energy storage (50) in the preloaded state, —a trigger mechanism (90) operationally engageable with the interlock (70) and operable i) to release a first portion of the mechanical energy stored in the mechanical energy storage (50) when actuated for a first time and ii) to release at least a second portion of the mechanical energy stored in the mechanical energy storage (50) when actuated for a second time

Abstract: The present disclosure relates to a mechanical energy storage for a fluid dispensing device (10), the mechanical energy storage comprising:—a first drive spring (51) extending along a longitudinal direction (z),—the drive spring (51) comprising a first longitudinal end (53) to engage with a housing (10) of the fluid dispensing device (1) and a second longitudinal end (54) opposite to the first longitudinal end (53) to engage with a driver (30) movable relative to the housing (10) along the longitudinal direction (z),—wherein the mechanical energy storage (50) is reversibly transferable into a pre-loaded state by resiliently compressing the first drive spring (51) in the longitudinal direction (z) to thereby induce a resilient deformation of the first drive spring (51) in a first direction (y) transverse to the longitudinal direction (z), and-wherein the mechanical energy storage (50) is transferable from the pre-loaded state into an unloaded state by allowing the first drive spring (51) to relax into or towar

Abstract: According to various embodiments, an air-handling apparatus includes: a housing having a plurality of vertical walls; an air inlet that is disposed in one of the plurality of vertical walls and is configured to receive first air into the air-handling apparatus while the first air moves in a first direction; an air outlet that is disposed in one of the plurality of vertical walls and is configured to discharge second air from the air-handling apparatus while the second air moves in a second direction, wherein the first direction differs from the second direction by at least 90 degrees; a centrifugal fan that is disposed within the housing and receives the first air and discharges the second air; and an air temperature-conditioning component that is disposed within the housing and in the path of one of the first air or the second air.

Abstract: A heating, ventilation, and/or air conditioning (HVAC) system includes a conduit assembly with a first conduit segment, a second conduit segment, and a rotational fitting fluidly coupling the first conduit segment and the second conduit segment to one another. The conduit assembly is configured to fluidly couple to a port of a heat exchanger of the HVAC system, and the rotational fitting is configured to enable the first conduit segment and the second conduit segment to rotate relative to one another between a first orientation and a second orientation and maintain a connection between the first conduit segment and the second conduit segment during relative rotation between the first conduit segment and the second conduit segment.
