    • To permit continued operation of a vehicle in spite of malfunction of an electronic ignition computer system, or any other electronic control module in an automotive vehicle, a transducer (10) provides an output to a trigger stage which has its output connected a digitally operating microprocessor (17) and to a bypass or transfer switch (21). The output from the microprocessor is connected to an analog and operating output stage (19, 20) to be controlled by the digital system of the microprocessor (17). Upon sensing of low operating voltage (U) as determined, for example, by a threshold switch (22), or of starting condition the switch (21) is closed, bypassing or interrupting connection to the microprocessor, and directly connecting signals from the transducer output stage to the input of the ignition circuit to permit operation under emergency conditions. The analog portion of the system is a single integrated module, separate from the digitally operating microprocessor (17) for ease of error diagnosis, maintenance and repair. This is particularly important with digitally operating control systems (17) which are subject to malfunction under low voltage conditions or upon occurrence of stray or distrubance signals in the network, for example under starting conditions.

    • An imaging system selects a medical imaging protocol using a repository of information associating multiple ranges of contrast agent peak time with corresponding different imaging protocols. An imaging protocol comprises a method for acquiring images using an imaging system and using data identifying at least one of (a) an imaging rate within an imaging scan cycle and (b) an interval between imaging scans. A contrast agent peak time comprises a time a contrast agent concentration substantially reaches a peak value in an anatomical region of interest of a patient relative to a time of start of contrast agent injection. A contrast agent peak time detector detects a contrast agent peak time. An imaging processor adaptively selects an imaging protocol from the imaging protocols in response to a comparison of a detected contrast agent peak time with at least one of the plurality of ranges.

    • A method for creating a resultant image for a specifiable, virtual x-ray quanta energy distribution includes capturing a first image dataset of the patient, capturing at least one second image dataset of the patient, and specifying a virtual x-ray quanta energy distribution. The method also includes establishing a spatial density distribution of the patient for at least two materials based on the first image dataset and the at least one second image dataset. The method includes creating a third image dataset of the patient based on the specified virtual x-ray quanta energy distribution and the established spatial material density distributions. The third image dataset represents an x-ray attenuation distribution of the patient corresponding to the specified virtual x-ray quanta energy distribution. The method also includes creating the virtual image from the third image dataset.
