摘要： A Single Piezo-Actuator Rotary-Hammering (SPaRH) Drill includes a horn actuator having high power piezoelectric materials and a flexure pre-stress to increase the actuators effectiveness. The drill is a low mass, low power, compact coring drill measuring 20-cm high by 7-cm diameter and having a total weight of 2 kg including drive electronics. Using an average power of 50-Watts, the drill basalt is expected to cut basalt at a rate of 0.2 cm/min down to depth of 10-cm and create cuttings and an intact core. The drill is expected to operate under different environments including Martian ambient (6 Torr and down to −50° C.), and liquid nitrogen temperatures (77 K) and low pressure (

摘要： Apparatus for probing, sensing, testing penetrating and sampling a medium generally includes an actuator (12) for generating vibrations at ultrasonic frequencies and a horn (14) coupled to the actuator (12) for amplifying the actuator vibrations along with a non-rotating coring and drilling bit (16) for penetrating the medium. A bit (16) includes a drill stem (20) attached to the horn (14) and a bore (26) extends through the bit (16), horn (14) and actuator (12) for withdrawal of samples. A free mass (36) is disposed between the horn (14) and the drill stem (20) for oscillating therebetween in response to the actuator vibration for causing migration of medium debris around and through the actuator bore for effectively self-cleaning of the bit (16). The hammering action of the free mass (36) is used for penetration of the medium and for analysis of the medium though the use of spaced apart accelerometers (92 and 94).

摘要： The invention provides a novel jackhammer that utilizes ultrasonic and/or sonic vibrations as source of power. It is easy to operate and does not require extensive training, requiring substantially less physical capabilities from the user and thereby increasing the pool of potential operators. An important safety benefit is that it does not fracture resilient or compliant materials such as cable channels and conduits, tubing, plumbing, cabling and other embedded fixtures that may be encountered along the impact path. While the ultrasonic/sonic jackhammer of the invention is able to cut concrete and asphalt, it generates little back-propagated shocks or vibrations onto the mounting fixture, and can be operated from an automatic platform or robotic system.
摘要翻译：本发明提供了一种利用超声波和/或声波振动作为功率源的新型手提锤。它易于操作，不需要大量的培训，从而使用户的身体能力要求更低，从而增加潜在操作员的数量。重要的安全优点是它不会破坏弹性或柔性材料，例如可能沿冲击路径遇到的电缆通道和管道，管道，管道，布线和其他嵌入式固定装置。虽然本发明的超声波/超音速手推刀能够切割混凝土和沥青，但是它在安装夹具上产生很少的反向传播的冲击或振动，并且可以从自动平台或机器人系统操作。

摘要： A system and method for monitoring the properties of a fluid, such as water, in a steam pipe without mechanically penetrating the wall of the pipe. The system uses a piezoelectric transducer to launch an ultrasonic probe signal into the pipe. Reflected ultrasonic signals are captured in a transducer, which can be the same transducer that launched the probe signal. The reflected signals are subjected to data processing, which can include filtering, amplification, analog-to-digital conversion and autocorrelation analysis. A result is extracted which is indicative of a property of the fluid, such as a height of the condensed fluid, a cavitation of the condensed fluid, and a surface perturbation of the condensed fluid. The result can be recorded, displayed, and/or transmitted to another location. One embodiment of the system has been constructed and tested based on a general purpose programmable computer using instructions recorded in machine-readable non-volatile memory.

摘要： The present invention is an automated crawling robot system including a platform, a first leg assembly, a second leg assembly, first and second rails attached to the platform, and an onboard electronic computer controller. The first leg assembly has an intermittent coupling device and the second leg assembly has an intermittent coupling device for intermittently coupling the respective first and second leg assemblies to a particular object. The first and second leg assemblies are slidably coupled to the rail assembly and are slidably driven by motors to thereby allow linear movement. In addition, the first leg assembly is rotary driven by a rotary motor to thereby provide rotary motion relative to the platform. To effectuate motion, the intermittent coupling devices of the first and second leg assemblies alternately couple the respective first and second leg assemblies to an object. This motion is done while simultaneously moving one of the leg assemblies linearly in the desired direction and preparing the next step. This arrangement allows the crawler of the present invention to traverse an object in a range of motion covering 360 degrees.

摘要： An acoustical transducer is provided with an acoustically absorbant backing material having an acoustical impedance precisely matching the impedance of the piezoelectric element in the transducer. The backing material is a multiphase mixture of selected materials, such as a low melting point alloy (InPb) and one or more powders having high impedance characteristics (tungsten and copper). The slope of the curve impedance versus volume fraction of the backing components is low, thus allowing the impedance of the material to be precisely controlled. The backing material is preferably electrically conductive and is fuzed to one surface of the piezoelectric element to further improve the output characteristics of the transducer.
