A method for controlling fluid ratio accuracy during a dual flow injection with a powered injection system is described. The method includes predicting a first capacitance volume of a first syringe comprising a first medical fluid and a second capacitance volume of a second syringe comprising a second medical fluid with a first capacitance correction factor and a second capacitance correction factor, respectively, selecting a ratio of the first medical fluid and the second medical fluid to be administered to a patient in the dual flow injection, determining a relative acceleration ratio of a first piston of the first syringe and a second piston of a second syringe based on the predicted first capacitance volume and the predicted second capacitance volume, wherein the relative acceleration ratio is selected to maintain the selected ratio of the first medical fluid and the second medical fluid during the dual flow injection, and injecting a mixture of a first medical fluid and a second medical fluid having the selected ratio with the powered injection system.

The first surface has a first concave surface portion (130) at or adjacent the first leading edge and a first convex surface portion (132) at or adjacent the first trailing edge.

A fluid path set includes a first fluid line having a proximal end fluidly connectable to a source of a first fluid and a second fluid line having a proximal end fluidly connectable to a source of a second fluid. A flow mixing device is in fluid communication with distal ends of the first and second fluid lines. The flow mixing device includes a housing, a first fluid port provided for receiving the first fluid, and a second fluid port for receiving the second fluid. A mixing chamber is disposed within the housing and is in fluid communication with the first and second fluid ports. A third fluid port in fluid communication with the mixing chamber for discharging a mixed solution of the first and second fluids. A turbulent flow inducing member is disposed within the mixing chamber for promoting turbulent mixing of the first and second fluids.

A synthetics rules creation processor or portal recognizes correlations between vehicle data and conditions, corporate knowledge and memory, company proprietary information, vehicle location, customer reported symptoms, and vehicle electronic control module fault codes. The synthetics rule creation processor or portal generates synthetic rules based on the correlations. A synthetic fault processor or synthetics engine compares current vehicle data and conditions, vehicle location, customer reported symptoms, and fault codes against the synthetic rules. The fault processor or synthetics engine generates synthetic fault codes based upon matching comparisons. The at least one synthetic fault code, along with an action plan, thereafter becomes part of a vehicle health report.

Embodiments of the present invention relate to a mixing apparatus.
