Abstract: Various embodiments described in this disclosure relate to techniques and related systems for database management, and some embodiments relate more specifically to techniques for processing hierarchical data structures having nodes with dependent-attributes using relationship objects, updating such dependent node attributes, and reporting engines that use databases that use such data structures.

Abstract: A process, apparatus, and method for online control and database collection and management of a computerized detection, tracking, and feedback control system. The system tests for nutrients by Raman scattering effects on skin or other tissues to determine the content of carotenoids or other nutrients as evidenced in that skin. Serum levels of nutrients may vary dramatically with time, but skin tissues may average such nutrition over time. Skin and other tissues may be scanned with light to produce accurate measurements of carotenoids or other nutrients accumulated in the skin based on the Raman scattering affect of those nutrients in the skin. A score can be derived from a properly calibrated bio-photonic scanner to reflect an averaged effective uptake of the detected nutrient (e.g. such as the carotenoid example).

Abstract: A chassis construction particularly useful for electronic equipment comprises a rectangular supporting panel, front and rear frame members of open rectangular configuration secured to the supporting panel, and a pair of side members. The front and rear frame members are formed with recesses, and the side members are formed with inwardly-extending tongues received in the recesses and secured to the front and rear frame members by fasteners passing through the tongues and recesses to thereby strengthen the chassis against torsion and bending forces.
