摘要： An apparatus for testing an implant having first and second components coupled together by an articulating ball and socket joint includes a support structure in contact with the first component of the implant for supporting said implant, an adapter coupled to the second component of the implant, and a load assembly in contact with the adapter for applying a load onto a semispherical surface of the adapter. The apparatus includes a drive assembly coupled with the adapter having a first drive shaft having a first end connected with a center of a rotatable wheel and a second drive shaft having a first end connected with an outer region of the wheel and a second end connected to the adapter. The second drive shaft has a longitudinal axis that is at an angle relative to the longitudinal axis of the first drive shaft. In operation, rotation of the first drive shaft about the longitudinal axis thereof causes articulating movement of the adapter, which in turn causes articulating movement of the first and second components of the implant under load.

摘要： A mechanical testing device has a rigid frame and a piezo translator connected to the frame. A Wheatstone bridge is connected to the translator to produce an electrical signal related to the compression of the translator, wherein a sample positioned between the piezo translator and the frame is subjected to loads by the movement of the translator. A sensor detects the force applied to the sample by the piezo translator, and produces a signal indicative of the force. A computer receives the Wheatstone bridge electrical signal and the signal indicative of the force applied to the sample. The computer controls the advancement of the translator to allow the application of precise amounts of compression to the sample.

摘要： A ceramic socket or ceramic socket insert for a hip joint prosthesis is tested prior to implantation in a human body by subjecting the portions of the interior of the socket or socket insert to a load that generates stresses that are greater than the physiological load. This may be accomplished either by pressing a hemispherically-shaped deformable material such as polymer or plastic into the interior of the socket or socket insert or by exposing the interior of the socket or socket insert to a fluid under pressure. The interior of the socket or socket insert may be sealed off with a test punch that has a supply line for the fluid. To reduce the amount of fluid that is required, the test punch may have a bulge that projects into the interior of the socket or socket insert and leaves only a gap for the fluid. In the method of testing, the interior of the socket or socket insert is subjected to a load that generates stress such that a defective socket or socket insert is destroyed and a non-defective socket or socket insert survives unharmed.

摘要： The condition of hair or other keratin fibers can be evaluated by measuring the force required to obtain a first value of elongation of the fiber in the yield region of the force-elongation curve, and the force required to obtain a second value of elongation of the fiber in the yield region. The ratio of these two measured forces is then determined as a damage index for the fiber. It is found that a constant force ratio is obtained for wet virgin keratin fiber independent of fiber diameter or the source of the fiber. It is also found that the force ratio changes as a function of subjective or objective measures of chemical damage to the hair fiber. The force ratio or damage index can, therefore, be used for identifying hair care products suitable for application to the hair without inducing unacceptable damage. The tests may be performed with simple tensile testing apparatus without tedious examination of the hair under a microscope.
摘要翻译：毛发或其他角蛋白纤维的状态可以通过测量在力 - 伸长率曲线的屈服区域中获得纤维的第一伸长率值所需的力，以及获得第二伸长率值所需的力纤维在产量区域。然后将这两个测量的力的比率确定为纤维的损伤指数。发现与纤维直径或纤维来源无关的湿原始角蛋白纤维获得恒定的力比。还发现力比随着对头发纤维的化学损伤的主观或客观测量的变化而变化。因此，力比或损伤指数可用于鉴定适用于头发的护发产品，而不引起不可接受的损伤。可以用简单的拉伸试验装置进行试验，而不用在显微镜下对头发进行繁琐的检查。

摘要： An apparatus for measuring mechanical characteristics of a material capable of transmitting vibration, particularly skin of a living subject. An impulse from a generator such as a small hammer causes a disturbance to propagate a wave along the material. A receiver includes a source of radiation and two photocells spaced apart and isolated from each other. The photocells receive the radiation after reflection from spaced locations on the surface of the material. The travel time of the propagated wave between the two reflection points is measured to determine the speed of wave propagation in the material.
