The method further includes generating, by the controller, calibration data for the flow sensor using a reference flow value of the flow rate when the flow control device has achieved the target flow rate and a corresponding flow measurement from the flow sensor.

Abstract: A scope may include an adjustment dial, which may be moved among a plurality of positions to configure the scope to compensate for projectile drops. The adjustment dial may be labeled with dial-calibration data, which may include one or more distance indicators and/or one or more windage hold-off indicators. The scope may be attached to a gun, bow or crossbow and the dial-calibration data may be at least partially generated using ballistics performance data based on shots, bullets, arrows or bolts fired by the gun, bow or crossbow. The dial-calibration data may be at least partially generated using shooting conditions. A system and method for generating customized adjustment dials can incorporate ballistics, projectile, and/or shooting conditions into program. The system and method can also include a derived distance calculation module, which may be configured to use a distance to a target and actual shooting conditions to calculate a derived distance.

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).
