    Abstract: The compressibility of a formation hydrocarbon sample is determined downhole by using a borehole tool to obtain the sample downhole, and, at two different pressures, subjecting the sample to near infrared illumination and conducting spectral absorption measurement of peaks at and/or around about 6,000 cm−1 and/or at and/or about 5,800 cm−1 (the absorption peaks of methane and crude oil respectively). The compressibility of the sample is determined from the change in the peak areas, the change in pressure, and the measured peak area itself. According to a preferred embodiment of the invention, the pressure is changed at least 2000 pounds per square inch (psi), and preferably 4000 or more psi between measurements.

    Abstract: Systems and methods are provided for fabricating compliant spring contacts for use in, for example, IC packaging and interconnection between multi-layers in stacked IC packages and electronic components. Internal stresses generated within an formed film are released to cause the film to buckle and/or bow away from a supporting terminal. A thin stressed metal film layer is selectively broken away from the substrate of the supporting terminal allowing the stressed metal film to take on a bowed and/or spring-like shaped through minute deformation based on a release of the internal stresses. The resultant thin compliant spring contact can deform a small amount as the spring contact is then pressed against a compatible mating contact surface in an overlying layer.
