摘要： The present invention discloses a modular MRI imaging system. The imaging system includes MRI radio-frequency antenna arrays separate from the patient support structure. The antenna arrays are affixed to a thin, flexible film such that they may be located next to the anatomical region of interest. In addition, multiple antenna arrays may be configured in various planar or three-dimensional arrangements to optimize the FOV and SNR. Separate patient support structures are provided that enhance ergonomics and patient stabilization. By removing the antenna from the housing, the support structures may be designed without the constraints of supporting the antenna or the associated electronics. The MRI imaging system further employs a preamplifier module. The preamplifier module houses the preamplifier and much of the other associated circuitry for each of the antennae. The preamplifier module operates to combine the signals from the antenna arrays and pass the signals to the MRI system.

摘要： Circuits and methods to minimize total harmonic distortion in an integrated circuit feedback amplifier. Complementary transistors in the signal path are selected so that their base-to-collector capacitances are matched. Additionally, the DC operating currents of such transistors are matched, thereby cancelling non-linearities due to base-to-collector capacitances.

摘要： The movement of the intensifier piston in a fuel injector, to control the pressurization of fuel, can be controlled with a flow control valve. The flow control valve provides different flow rates depending upon the direction of flow. In a first direction, flow control valve has a first rate of flow and in the second direction flow control valve allows a second different rate of flow. Typically, this can be applied to a intensifier piston as follows: flow traveling to the intensifier piston, in the first direction, has a first flow rate, allowing the intensifier to move downward and pressurize fuel. When injection is over, and the intensifier piston is vented, the flow control valve allows a second flow rate which is greater than the first flow rate, allowing the intensifier piston to vent quickly and reset for another injection.
