    摘要： One embodiment of the invention includes an inertial system. The system includes at least one inertial sensor configured to measure an inertial parameter associated with each of at least one axis. The system also includes a calibration system configured to sequentially measure an inertial calibration parameter at each of a plurality input axes. The system further includes an inertial processor configured to calculate motion of the inertial system based on the inertial parameter associated with each of the respective at least one axis and the sequential measurements of the inertial calibration parameter at each of the plurality of input axes.

    摘要： A CVA system includes a sensor system including a pendulous element that rotates about a first axis via first flexures in response to an input acceleration provided along a second axis that is orthogonal with respect to the first axis. A torque-summing gimbal is coupled to the pendulous element via the first flexures and coupled to a housing via second flexures. The system further includes an accelerometer controller that monitors a pickoff signal of the rotation of the pendulous element from a first electrode coupled to the pendulous element and to provide a forcer signal to at least one second electrode coupled to the torque-summing gimbal to force the torque-summing gimbal to rotate about the second axis via the second flexures based on the pickoff signal to provide Coriolis force-rebalance of the pendulous element. The accelerometer controller can determine the input acceleration based on the rotation of the torque-summing gimbal.

    摘要： A mounting and fastening system includes a mounting adapter configured to adapt mounting of a second component with respect to a first component, and having a radially inward portion including a throughbore, and a radially outward portion with a tapered outward surface that tapers in an axially inboard and radially inward direction and that cooperates with a tapered surface of the second component and such that an adapter inboard surface faces a first outboard surface of the first component. A mounting bolt for a mounting a fastening system includes: a head including flat opposite sides and semi-cylindrical opposite sides interposed between the flat opposite sides; a shank extending from the head; an external thread on at least a portion of the shank; a passage extending through the head and into at least a portion of the shank; and an internal thread in at least a portion of the passage.

    摘要： A fastener and retainer assembly includes a threaded fastener having a head and a retainer projecting laterally from the head to engage adjacent structure and retain the head against rotation during threading. The retainer includes, and preferably consists essentially of, a one-piece metal stamping having raised embossments and/or a raised edge flange to strengthen the retainer against bending during use. The retainer preferably has a generally planar body from which the embossments and/or the edge flange extends.

    摘要： The breathing bag has an upper region; a lower region; a conduit for delivering exhaled air to the lower region and a conduit for withdrawing breathable air from the upper region. The device also has a baffle mounted therein for entrapping exhaled air in the lower region and for causing the exhaled air to remain in a low turbulence mode, for promoting a separation of oxygen and carbon dioxide from the exhaust air by stratification and for causing carbon dioxide to accumulate in the lower region of the bag. Consequently, the breathable air rising from the lower region of the bag has a higher oxygen content. In another aspect of the invention, a method for separating carbon dioxide and oxygen by stratification from exhaled air is also described.

    摘要： In one implementation, a chamber is selected that accommodates an array of die structures that comprises one or more cavities. An inner chamber of the chamber is maintained at a first temperature. An alkali metal source of the chamber is maintained at a second temperature greater than the first temperature. An outer chamber of the chamber is maintained at a third temperature greater than the first temperature and the second temperature. The one or more cavities of the array of die structures are filled with a portion of the alkali metal source. The one or more cavities of the array of die structures are sealed to comprise the portion of the alkali metal source.
