Abstract: A method of adaptively sampling data to determine the start of injection in a solenoid actuated valve of a fluid injector includes, in an operating cycle or portion thereof of the valve, sampling the signal of current through a solenoid of the valve at sampling points having a pre-defined interval therebetween. At each sampling point, determining the value of the first derivative of current and detecting the sampling point at which the first derivative achieves a maximum as the start of injection. Values of the first derivative of the sampling points immediately preceding and immediately following the start of injection are determined. In a subsequent operating cycle, synchronisation of sampling is altered to shift sampling times depending on the values of the first derivative of the sampling points immediately preceding and immediately following the start of injection.

Abstract: A liquid transfer apparatus comprises an output terminal device, a receiving terminal device, a connecting pipeline, and a control device. The output terminal device includes a first pressurizing member for filling the first storage container with high-pressure air. The receiving terminal device includes an air pressure adjusting member for adjusting the air pressure inside the second storage container. When the liquid transfer apparatus is in a non-transferring state, the air pressure inside the second storage container is high enough to prevent the liquid in the first storage container flow into the connecting pipeline. And when the liquid transfer apparatus is in a transferring state, the pressure difference between the inside of the first storage container and the inside of the second storage container is sufficient to drive the liquid in the first storage container to enter the second storage container.
