Abstract: A system and method for performing quiet magnetic resonance imaging (“MRI”) are provided. An MRI system is directed to perform a pulse sequence that includes a magnetic field gradient s tapped through a plurality of different gradient component amplitude values in a manner that controls the difference between successive gradient amplitudes. In this way, force changes generated during the transition from one gradient component amplitude to the next are controlled, thereby resulting in a significant noise reduction. Additionally, the gradient amplitude values are ordered such that the transition of the gradient component amplitude in successive repetitions of the pulse sequence is controlled, thereby mitigating the generation of forces between pulse sequence repetitions.

Abstract: An electronic device holder, having a base having an insert aperture therein, an insert positioned in the insert aperture, and a one-piece flexible member connected to the base for supporting an electronic device disposed in the insert.

Abstract: A hinge mechanism for pivotally connecting first and second housings of a portable electronic device for movement between closed and open positions, the mechanism comprising a hinge shaft mounted for rotation with the first housing and providing a camming surface, and resilient means mounted for rotation with the second housing and arranged to cooperate with the camming surface so as to vary loading of the resilient means on the camming surface for relative rotation therebetween.
