摘要： An apparatus and method for monitoring and reporting downhole bit failure. Sensors are located on a sub assembly (which is separate from the drill bit itself but located above it on the drill string). Data from the sensors (preferably accelerometers) are collected in blocks, then analyzed in the frequency domain. The frequency domain is divided into multiple bands, and the signal power in each band is compared to that of another band to produce a ratio of powers. When a bit is operating at normal condition, most of the spectral energy of the bit vibration is found in the lowest frequency band. As a bearing starts to fail, it produces a greater level of vibration in the higher frequency bands. This change in ratios is used to determine probable bit failure. Bit failure can be indicated by a given ratio surpassing a given threshold, or by monitoring the standard deviation of the frequency ratios. When the standard deviation exceeds a certain value, a failure is indicated.
摘要翻译：一种用于监测和报告井下钻井故障的装置和方法。传感器位于子组件（与钻头本身分离但位于钻柱上方）。来自传感器（优选加速度计）的数据以块为单位收集，然后在频域中进行分析。将频域划分为多个频带，并将每个频带中的信号功率与另一频带的信号功率进行比较以产生功率比。当一个位在正常条件下运行时，位振动的大部分频谱能量被发现在最低频带。随着轴承开始失效，它在较高频段产生较大的振动水平。这种比率变化用于确定可能的位故障。位故障可以通过超过给定阈值的给定比例来表示，或者通过监视频率比的标准偏差来指示。当标准偏差超过一定值时，会出现故障。

摘要： An ultrasonic probe for use in an ultrasonic diagnosis apparatus for a living body comprises an array transducer made up of a plurality of layered transducer elements. A specified structure (face-to-face structure) is created across two adjacent transducer elements. In each transducer element, a first vertical electrode layer for ground is connected with a top electrode layer and an inner electrode layer, and a second vertical electrode layer for signal is connected with a bottom electrode layer and an inner electrode layer. When creating the specified structure, steps including formation of slits in a layered assembly and filling of the slits or the like are repeated. By finally forming a plurality of separating slits, the layered assembly is divided into a plurality of transducer elements. On the other hand, each transducer element is compounded in the horizontal direction. The compounding is performed at any stage of before, during or after formation of the specified structure.

摘要： An externally-powerable sensor is described for detecting ultrasonic energy and for providing an accurate indication of the level of such energy to an external monitoring device over a wide dynamic range. A first electrical signal proportional to the detected ultrasonic energy is chopped by the output of a free-running multivibrator to generate a signal having a frequency differing from the frequency of the first signal by an amount within the audio frequency range. Such difference signal is selectively amplified to concentrate the spectral energy of the difference component in a lower portion of the audio range. A low pass filter extracts, from the so-concentrated difference signal, a modified audio signal whose frequency content is at the lower end, illustratively 0-6 KHz, of the spectrum of the concentrated difference signal. The output of the low pass filter is processed to generate a DC output current that is proportional to the detected ultrasonic energy level. The sensor is connectable to a 4-20 mA current loop which serves to power the sensor electronics as well as to carry the DC output current to the monitoring device.

摘要： An ultrasound transducer array (408) includes at least one transducer element (412) having a first (604) and second (606) portions separated by an acoustical discontinuity (520). The first portion (604) has the desired length to form a half-wave k31 resonance, while the second portion (606) has a resonant length for an undesired very low frequency out-of-band k31 resonance. The thickness of the transducer element (412) is designed for k33 half-resonance. Given the design, the transducer element (412) can operate and provide for both forward-looking (514) and side looking (512) elevation apertures. A method is also disclosed for using the disclosed ultrasound transducer (412) in ultrasound imaging.

摘要： The invention concerns an ultrasonic tomograph for spatial and temporal characterisation of moving fluids such as air and water. Said tomograph comprises a plurality of pairs of ultrasonic transceiver probes, each pair capable of being oppositely inscribed on a circle around a fluid line of flow. The probes are therefore arranged on either side of the flow and neither modify nor disturb it. Each probe is capable of moving on a plane perpendicular to the line of flow. Indeed each probe is associated with a step motor. Each probe is a piezoelectric ceramic traducer which does not suffer any drift in time and which does not require re-calibration, which provides the inventive tomograph with temporal stability. Moreover, said tomograph is robust since said ultrasonic probes can be used in extreme conditions. The frequency of the ultasounds range between 30 kHz and 300 kHz.
