摘要:
An airbag inflator (10) including an elongated outer housing (12) having an interior and one or more orifices (22) formed therealong to enable fluid communication between the outer housing interior and an exterior of the outer housing (12). The outer housing orifice(s) (22) open from the outer housing interior toward a first side (F) of the inflator. An elongated inner housing (14) is positioned in the outer housing interior. The inner housing (14) has an interior and one or more orifices (20) formed therealong to enable fluid communication between the inner housing interior and an exterior of the inner housing (14). The inner housing orifice(s) (20) open from the inner housing interior toward a second side (S) of the inflator. A quantity of a gas generant composition (16) extends along a portion of the interior of the inner housing (14). The gas generant (16) has a substantially “C”-shaped cross-section with a slot (24) extending along the length of the gas generant (16). The gas generant slot (24) is oriented facing the inner housing orifice(s) (20). A filter (15) is positioned intermediate the inner housing orifice(s) (20) and the outer housing orifice(s) (22) for filtering combustion products generated by combustion of the gas generant composition (16). An igniter (40) is operatively coupled to the gas generant composition (16) so as to enable fluid communication between the igniter (40) and the gas generant composition (16) upon activation of the inflator (10). The slotted, “C”-shaped cross section of the gas generant (16) provides a greater exposed gas generant surface area than would be achievable without the slot (24). This enhances the ignition and burning of the gas generant composition (16) upon inflator activation.

According to one aspect, a nuclear magnetic resonance (NMR) radio-frequency (RF) coil of an NMR spectrometer includes oppositely-facing arches at opposite longitudinal ends of the coil window, along shielded regions of the coil. The arched coil shapes allow situating the transverse parts of the coil away from the interfaces between the sample measurement volume and coil shields while minimizing the additional coil length and thus coil inductance and capacitance needed to move the transverse conductors away from interfaces. Moving the transverse parts of the coil away from the measurement volume facilitates shimming. The coil may be lifted on a plurality of longitudinal support rods spaced around a circumference of the coil, in order to reduce the capacitance between the coil and associated shields.

According to some embodiments, low-temperature (cryogenic) nuclear magnetic resonance (NMR) probe fixed capacitors include thermally-conductive dielectric layers serving to thermally connect the capacitors to a cryogenic heat sink. For example, a sapphire layer may be metalized on opposite sides to form copper capacitor plates, and along an edge to form a copper heat sink contact. Heat generated by RF currents during an operation of an NMR circuit including such a capacitor is discharged through the thermally-conductive dielectric to the heat sink. Cooling cold-probe circuit components such as capacitors through thermally-conductive capacitor dielectrics allows reducing perturbations introduced into the circuit by components such as heat sinks.
