A device, method, and computer readable medium are disclosed. The manufacturing process utilizes tape casting in the drying procedure in which a catalyst slurry is cast on a substrate and dried at a temperature of between about 50\xb0 C. A signal-to-noise ratio of the second signal is measured, and the SNR of the first signal is determined based at least in part upon the measured SNR of the second signal. A claw portion to be secured to the light source unit can be provided on the attachment leg. Upon pressurization of the actuator, the flexible body of the actuator will expand radially, causing relative contractile motion between the two end fittings. The spring contact elements may be mounted to either the DUTs or to the ASICs, and may fan out to relax tolerance constraints on aligning and interconnecting the ASICs and the DUTs.
