摘要： A squeeze-stretch (also called, herein push-pull) loudspeaker or driver, such as an electret, can operate in an active noise reduction (ANR) earplug application. Other embodiments of a squeeze-stretch loudspeaker, such as piezoelectric bimorph and balanced armature, operate in a similar way, although they will differ in detail. Other applications, such as earphones for communication and entertainment, will benefit from the compact arrangement of components in a squeeze-stretch design. The advantages are a greater sound output from a smaller package, a smooth frequency response, and because of the diaphragm arrangement, less sensitivity to vibration.

摘要： An apparatus compares the torque from an MOV motor with the valve displacement, and from the comparison assesses MOV operating condition. A transducer measures the vibration of the housing of an MOV. The vibrations are due to the motions of the rotating elements within the housing, which motions are directly related to the motion of the valve relative to its seat. Signal processing apparatus analyzes the vibrations to recover the rotations of the rotating elements and thus the motion of the valve plug. Lost motion can also be determined (if a lost motion connection exists) by demodulating the vibration signal and thus taking into account also the lost motion. Simultaneously, the forces applied to the valve are estimated by estimating the torque between the stator and the rotor of the motor. Such torque can be estimated from measuring the input current and voltage alone, using a forgetting factor and a correction for the forgetting factor. A signature derived from relating the torque to the valve position can be used to assess the condition of the MOV, by comparing the signature to signatures for MOVs of known conditions. The vibration analysis components generate signals that relate to the position of elements in the operator. Similarly, the torque estimator estimates the torque output by any type of electric motor, whether or not part of an MOV analysis unit.

摘要： X-ray tube noise is reduced by coupling the stator mass to the neck section of the glass vacuum tube so that vibrations are dissipated by the stator and not transmitted to the bulk of the vacuum tube. The coupling is accomplished with a non-magnetic sealing material such as an epoxy sealant. The sealant will generally fill the gap between the stator and the neck section of the vacuum tube. Alternatively, the coupling can be done with a mechanical clamping device.

摘要： A composite panel is described in which the face sheets and the core have properties such that the panel produces a double wall resonance near the low frequency end of the principal speech bands and in which the panel produces interaction between the symmetric and antisymmetric mode in the principal speech bands, thereby providing greater than mass-law transmission loss over a substantial portion of the audio frequency spectrum. At frequencies above the principal speech bands effects are determined primarily by the properties of the individual face sheets.
