    摘要: An integrated regulated current drive circuit for driving a squib of an inflatable airbag has a current sense resistor connected in series with a load, and a reference resistor connected in series with a reference current source. Both resistors are matched to define a precise ratio of resistance values which determines the amount of current fed to the squib. Both resistors are implemented by combining a number of identical on-chip resistor elements.

    摘要: A magnetic resonance imaging (MRI) system (100) performs optimized chemical-shift excitation. A computer system (110) performs a constrained numerical optimization to determine radio frequency (RF) pulse amplitudes, phase angles, and interpulse intervals for a binomial-like RF pulse sequence that will excite magnetization (41) of a selective one of two chemical species, such as water and fat for example, of a subject (102) in relatively less time and that may therefore be used at lower magnetic fields. A static magnet (132) produces a magnetic field along a predetermined axis relative to the subject Pulse sequence apparatus (134, 152, 154, 156, 158) creates magnetic field gradients with the magnetic field, applies RF pulsed magnetic fields, and receives resulting RF magnetic resonance (MR) signals. Pulse sequence control apparatus (142) controls the pulse sequence apparatus to apply the binomial-like RF pulse sequence to the subject. The computer system reconstructs an image from received RF MR signals resulting from application of the binomial-like RF pulse sequence.
