Comfortable earphone cushions

A cushion for a headset earphone comprises a resilient ring having opposite input and output faces, and a through-opening defining an interior surface between the two faces. The input face has structure for acoustically coupling the opening to an output face of an audio speaker, and the output face is resiliently conformable to a lateral face of an external ear of a listener, thereby acoustically coupling the opening, and hence, the speaker, to the listener's ear. The interior surface of the cushion can be configured to effectively match the acoustical impedance at the output face of the speaker to the acoustical impedance at the entrance of the listener's ear. In one possible embodiment, the ring is formed of an elastomer filled with microcapsules containing a material capable of an endothermic phase changes at a constant temperature, such that the cushion more effectively conducts heat away from the ear, thereby providing long term listening comfort. In another embodiment, the through-opening is acoustically coupled to the output of the transducer with an acoustic plug such that the cushion is flexibly articulated about the plug relative to the speaker, thereby enabling the cushion to comply more easily to the listener's ear using lower contact forces between the cushion and the ear.

NMR MAS inflow bernoulli bearing

An improved axial gas bearing for a gas-driven NMR MAS sample rotor is disclosed that utilizes inward flow with a low rotational component over a rotor conical end. A conical flow region is formed between the rotor conical end and a conical stator bearing surface such that the included angle defining the stator surface is not less than the included angle defining the rotor conical end. Gas is injected radially inward with a significant axial rearward component from a number of small holes at high velocity from the periphery into the conical flow region. Compared to the radial velocity components, the tangential flow components of the injected gas are small and preferably opposed to the direction of the rotor rotation. The high and accelerating negative radial velocities may result in significant Bernoulli effect, such that the mean axial pressure over the conical rotor end may be less than atmospheric pressure for a given axial clearance, but as the clearance decreases, the hydrostatic effects exceed the Bernoulli effects and the mean axial pressure over the conical rotor end may then exceed atmospheric pressure by a substantial amount. Thus, a self-stabilizing axial bearing is formed with improved stability and stiffness for rotor surface speeds up to at least 80% of the speed of sound. Motive power required to spin the rotor may be provided by a radial-inflow microturbine at the opposite end of the rotor in a way that is readily compatible with automatic sample change.
