摘要： An elastomeric pad structure coupled to an ultrasonic transducer provides excellent coupling and transmission for extradermal applications without requiring the glycerin gel couplant typically used for such applications. The material and shape of the face of the pad structure traps a small amount of liquid between the pad and the skin, providing an effective couplant not requiring further containment, rewetting, or clean-up. The elastomeric pad be releasably coupled to the ultrasonic transducer, and the various illustrative embodiments for coupling include the use of clips, adhesives, an adapter ring having a lip or grooves, a ring having pins for engaging holes in the elastomeric pad and the transducer, and a sleeve which employs pressure or friction to retain the elastomeric pad to the transducer. Uses for the system and method include extradermal applications such as ultrasonic bone growth stimulation through a window cut in a bone fracture cast.

摘要： A single critically damped acoustic stack yields a wide frequency range as an acoustic transmitter or as an acoustic transducer having particular use in well integrity determination. The critically damped present acoustic stack utilizes a plurality of stacked acoustic elements such as piezoelectric ceramics that are energized in two manners, providing different center frequencies; each producing a respective center frequency of 100% bandwidth to yield an acoustic stack having a total bandwidth exceeding the bandwidth of an acoustic element or the bandwidth of the plurality of acoustic elements. One manner of energizing is to pulse only one of the acoustic elements. The other manner is to pulse a first acoustic element the pulse a second acoustic element after a delay equal to the amount of time it takes for the first pulse to reach the face of the second acoustic element. The acoustic elements are bonded together and onto a critically damped backing of tungsten. The assembly is retained in a housing that is preferably made of PEEK. The acoustic stack is primarily used in pulse-echo analysis of metal casing wall thickness and cement bond quality detection of wells.

Yet another low frequency pulse-echo ultrasonic transducer comprises a transducer composite made from a lead metaniobate. Still another frequency pulse-echo ultrasonic transducer comprises a composite stack.

摘要： A pressure transducer suitable for use as a component of a passive occupant detection system installed in a passenger vehicle. The transducer comprises first and second contact members separated by a spacing member. The first contact member has on a surface thereof a primary contact comprising first and second terminations and portions spaced apart in a first direction. The second contact member has on a surface thereof a plurality of secondary contacts crossing and facing the spaced-apart portions of the primary contact through an opening in the spacing member. Application of an increasing force causes the contact members to move toward each other, causing an increasing number of the spaced-apart portions to be shorted out by the secondary contacts and causing an increasing number of secondary contacts to contact the primary contact, thereby altering the electrical path between the terminations of the primary contact.

摘要： A piezoceramic pulse-echo acoustic transducer includes protection layers for the piezoceramic that are tuned to the piezoceramic so as to optimize pulse-echo signal response (i.e. greater output signal bandwidth and increased return signal sensitivity). The protection layers are tuned to the piezoceramic via material selection and thickness. The acoustic transducer has a backing, a piezoceramic adjacent the backing, an intermediate protection layer adjacent the piezoceramic, and a front protection layer adjacent the intermediate protection layer and opposite the piezoceramic. The front and intermediate protection layers are tuned to the piezoceramic via their acoustic impedance such that the acoustic impedance of the intermediate layer is greater than the acoustic impedance of the piezoceramic and of the front protection layer. The acoustic impedance of the front protection layer is less than the acoustic impedance of the piezoceramic.

摘要： A device for acoustic measuring in a medium in a borehole such as velocity of sound in the medium or velocity of the medium, includes at least a first acoustic array situated in a first, slanted sidewall of a measuring area and operating to emit a series of acoustic waveforms across a measuring area. In one form, the device includes a second acoustic array situated in a second, slanted sidewall of the measuring area and operating to receive an acoustic signal resulting from the emitted series of acoustic waveforms or to receive said acoustic signal and emit a second series of acoustic waveforms. A the processor measures a time between when a predefined portion of one of the series of acoustic waveforms was emitted and when a predefined portion of the received acoustic signal corresponding to the predefined portion of one of the series of acoustic waveforms is received by the acoustic receiver, and correlates the measured time to a reference time, then outputs a correlation factor for determining the velocity of sound in the medium in the measuring area. The processor may also calculate transit time for the two emitted acoustic signals or echoes from the first emitted acoustic signals to determine medium flow velocity.
