Abstract: An engine control system comprises an air control module and a spark control module. The air control module controls a throttle valve based on a first desired torque when the throttle valve is in an operable state. The spark control module controls spark advance based on the first desired torque and a second desired torque when the throttle valve is in a fault state. The throttle valve is maintained in a predetermined fault position when in the fault state.

Abstract: An imaging system automatically determines a cardiac timing parameter for acquiring a cardiac image in a heart phase. An interface receives data identifying a heart image orientation for image acquisition. A repository of data associates, for acquisition of an image in a particular heart phase, different image orientations with corresponding different data items identifying respective corresponding particular acquisition points within an individual heart cycle relative to a start point of the heart cycle. An acquisition timing processor determines from the repository of data, a particular acquisition point within an individual heart cycle relative to the start point of the heart cycle, in response to the received data identifying the heart image orientation and uses the determined particular acquisition point to provide a synchronization signal for triggering acquisition of an image at the particular heart phase.

Abstract: A control system for a powertrain includes an energy determination module and a speed control module. The energy determination module determines a rotational energy input to the powertrain during a first period of a negative lash event of the powertrain. The speed control module selectively limits an increase in a rotational speed of the engine to a first predetermined rate based on the rotational energy during a second period of the negative lash event following the first period. The rotational energy is based on an acceleration rate of the rotational speed, and the speed control module limits the increase when the acceleration rate is greater than a predetermined acceleration rate. The speed control module further selectively increases the rotational speed at a second predetermined rate during a third period beginning at an end of the second period. A related method is also provided.

Abstract: An MR imaging system uses multiple RF coils, for reducing image acquisition time, suitable for chemical exchange saturation transfer (CEST) imaging. Multiple RF (Radio Frequency) coils provide CEST imaging preparation in an anatomical volume by providing multiple interleaved RF pulses. The multiple interleaved RF pulses provide substantially increased RF pulse sequence duty cycle in the multiple RF coils relative to a duty cycle provided by a single coil of the multiple RF coils. The multiple RF coils subsequently provide RF excitation pulses in a reduced anatomical volume using k-space undersampling in an accelerated imaging method using the multiple RF coils and enable subsequent acquisition of associated RF echo data for deriving a CEST image.

A zero pedal torque module selectively sets a zero pedal torque equal to the first minimum propulsion torque. A pedal request module determines a pedal torque request based on an accelerator pedal position, a vehicle speed, and the zero pedal torque. A driver request module determines a driver axle torque request based on the pedal torque request. A shaping module selectively shapes the driver axle torque request into a shaped driver axle torque request. A conversion module converts the first minimum propulsion torque into a minimum axle torque. A final driver request module sets a final driver axle torque request equal to a greater of the shaped driver axle torque request and the minimum axle torque.

Abstract: A method of operating an engine control system includes reducing pressures within cylinders of an engine based on an auto start command signal including: receiving a torque request signal; calculating a powertrain output torque; and controlling air flow to the engine based on the powertrain output torque. During a startup of the engine: electric motor torque is increased to a predetermined level and reduced to increase a current speed of the engine; combustion torque of the engine is activated and increased after the current speed is within a predetermined range and a manifold absolute pressure is less than a predetermined level; and the electric motor torque is increased based on a crankshaft output torque signal to increase a crankshaft output torque subsequent to the reducing of the electric motor torque and while performing the activating of the combustion torque.
