Abstract: A system comprises a light source, a scanner, a reference reflectivity material, a detector, and a processor. The light source is configured to emit light, and the scanner is configured to scan the emitted light across at least a portion of a reachable region including a field of regard through a window. The reference reflectivity material is included internally within a housing of the system and located in the reachable region but outside the field of regard. The detector is configured to detect at least a portion of the emitted light scattered by the reference reflectivity material. The processor is configured to analyze detected information from the detector to determine an electrical property of the emitted light.

Abstract: A method and apparatus for coupling a pre-wired end fitting with a shaped charge loading tube where the end fitting centers and orients the loading tube within a perforating gun and further includes a selective switch, feed through contact and orifices to insert a wireless detonator and detonating cord, the loading tube being pre-wired with insulated wire.

Abstract: An apparatus for imaging one or more selected fluorescence indications from a microfluidic device. The apparatus includes an imaging path coupled to least one chamber in at least one microfluidic device. The imaging path provides for transmission of one or more fluorescent emission signals derived from one or more samples in the at least one chamber of the at least one microfluidic device. The chamber has a chamber size, the chamber size being characterized by an actual spatial dimension normal to the imaging path. The apparatus also includes an optical lens system coupled to the imaging path. The optical lens system is adapted to transmit the one or more fluorescent signals associated with the chamber.
