摘要： A real-time, or synchronous, sensor data acquisition system (10) acquires physical characteristics or properties associated with a structure (14) or physical system using a plurality of sensors (18) coupled in series to a single cable (26). The sensors (18) may sense vibration, noise, temperature, acceleration, pressure, strain, force, etc. The sensors (18) transmit data along the cable (26) at greater than 100dB dynamic range, with a bandwidth between about 5 to 20 KHz, and in a digital, single bit wide data stream. The sensors (18) include modulators to code the data signals with distinct codes. A receiver has a demodulator to decode and separate the data signals.

摘要： An acoustic logging apparatus includes a tool body and a housing. A transducer operating in the bending mode is mounted in the housing. The transducer operates such that it is excited by or emits acoustic energy in only one of the two directions substantially perpendicular to the face of the transducer. The housing is mounted substantially removed from the axis of the body. An acoustic receiver includes an outer sleeve having a flange and a hat slidably mounted within the outer sleeve. The sliding of the hat compensates for variations in pressure and temperature. An acoustic transmitter includes a main housing and a hat slidably supported within the main housing. The sliding of the hat compensates for variations in pressure and temperature. Combinations of air gaps and o-rings in the transducer acoustically isolate a piezoelectric crystal from its housing and the housing from its enclosure. The acoustic receiver and acoustic transmitter are configured to be replaced in the field.

摘要： An apparatus and a method for providing three dimensional seismic images using directional sensing rotation within a geological structure's complete vector field produced by seismic energy emanating from seismic scatter's in the sub-surface of the geological structure, which significantly reduces the need for the distribution of seismic energy sources and receivers over the entire surface of the geological structure. The apparatus includes an omni-azimuthal source of seismic energy (22) positioned adjacent a surface of a geological structure (18) for emitting a signal (27) of sufficient energy and bandwidth to produce seismic energy (28 and 97) from the seismic scatters in the geological structure (18). A plurality of array of sensors (20) are also provided. Each array (20) has directional sensing receivers (30) aligned in the geological structure (18) for receiving and measuring the seismic energy (28 and 97) to create a complete vector field.

摘要： The inventive ultrasonic transducer (1) has a pot-shaped housing, the bottom surface of said housing being partly configured as an oscillating membrane (3). A stabilising ring is provided on the exterior surface of the wall of said pot-shaped housing. Said stabilising ring (6) gives the housing greater rigidity and restricts the ultrasonic oscillation essentially to the base of the pot shape (3) which forms the oscillating membrane. The propagation and reception beam of the ultrasonic waves can be shaped further by means of an additional sound-directing device (7) located in the area of the oscillating membrane (3).

摘要： A transducer array according to the invention includes forty-two acoustic transducers for use in a fluid medium, with each of the transducers having maximum lateral dimensions of less than one acoustic wavelength in the medium, whereby the transducers themselves tend to radiate isotropically. The elements of the array are located at the vertices of a regular geodesic two-frequency icosahedron. The transducer array also includes a driver or a receiver, or both, and arrangements for coupling them to the array elements. A switching circuit can couple the array elements alternately to the driver or receiver, depending upon the operating mode. A conventional delay controller is coupled to the acoustic transducers, for controlling an acoustic beam formed by the array. In a particular embodiment of the invention, the array is operated at frequencies selected so that the inter-transducer spacing of any two mutually adjacent transducers does not exceed 2 lambda /3, and is not less than lambda /3.

摘要： An ultrasonic applicator (2) comprises a coupling surface (6) on its underside. It contains an ultrasonic transducer (22) which is pivotally mounted on a swivelling axis (32) and which can be made to oscillate by means of two essentially mutually perpendicular gear wheels (28, 34) driven by a shaft (26) of a motor (26) for the purpose of scanning a scanning angle region (11). The longitudinal axis (17) of the motor is essentially perpendicular to the axis of symmetry (15) of the scanning angle region (11). During part of its oscillating movement, the ultrasonic transducer (22) penetrates a recess (30) in the gear wheel (28) nearer the motor. The gear wheel (28) nearer the motor has a notch (38) which is arranged so that the path of the ultrasonic wave to and from the ultrasonic transducer (22) is not affected when the transducer penetrates the recess.
