    摘要: An apparatus measures residual stress in a sample under test by measuring the penetration of an indenter on a unprocessed sample under test, and after processing of the sample under test, measuring again the penetration of the indenter on the processed sample under test, and deriving from the two penetration measurements the residual stress in a sample under test. The apparatus and method of the preferred embodiments are especially useful in determining residual stress in a printed wiring board. In this manner a direct measurement of residual stress is possible without destroying the printed wiring board.

    摘要: A method and system for cooling an electrical heat source is disclosed. A heat exchanger has two principal sub-assemblies. A closed-loop fluid flow is provided through a second sub-assembly, disposed next to a heat source. An open-loop fluid flow is provided though a first sub-assembly in communication with a second sub-assembly. Each of the first and second sub-assemblies has a rotational element. The fluid flow entering the first sub-assembly rotates the first rotational element, and magnetic communication between the rotational elements causes movement of the second rotational element, thereby achieving fluid movement within the second sub-assembly. Operationally, the closed-loop sub-assembly removes heat from the heat source and transfers it to the open-loop sub-assembly for subsequent heat transfer in a downstream fluid flow.

    摘要: A method and system for determining material properties of a cross-section of an anisotropic sample material. An ultrasonic signal is applied to the surface of the anisotropic sample material, which comprises multiple constituent material layers, such that a characteristic medium wave is induced within each of the constituent materials. Each of these characteristic medium waves is sampled over a time interval to obtain a test waveform. This resultant test waveform is then spectrum analyzed utilizing cepstrum noise filtration, such that the material properties of said anisotropic sample material may be determined.
