  • Patent number: 7696003
    Abstract: The present disclosure suggests various microelectronic component assembly designs and methods for manufacturing microelectronic component assemblies. In one particular implementation, a microelectronic component assembly includes a microelectronic component, a substrate, and at least one bond wire. The substrate has a reduced-thickness base adjacent terminals of the microelectronic component and a body having a contact surface spaced farther from the microelectronic component than a bond pad surface of the base. The bond wire couples the microelectronic component to a bond pad carried by the bond pad surface and has a maximum height outwardly from the microelectronic component that is no greater than the height of the contact surface from the microelectronic component.

  • Patent number: 7002348
    Abstract: An RF coil construction for MRI is disclosed. The construction includes a device for cryogenically cooling receiver coils, at least two coil elements being cryogenically cooled by the device and forming an array. Each coil element includes at least two capacitors for tuning and matching the coil element. The construction also includes a circuit connected to each coil element for decoupling the coil element from the transmitter coil(s), and also for decoupling among coil elements.

  • Patent number: 6583623
    Abstract: In magnetic resonance imaging, a pulse sequence is used to obtain both water-only and fat-only signals within a single acquisition time. Pulses and readout gradients are applied to take a proton-density-weighted image of the water, a proton-density-weighted image of the fat, and a T2-weighted image of the water. Between the first water readout gradient and the fat readout gradient, a spoiling gradient is applied to spoil the first water echo. Between the fat readout gradient and the second water readout gradient, a refocusing gradient is applied to refocus the second water echo. The proton-density-weighted images of water and fat are combined to form water-plus-fat images free of in-plane and through-plane chemical-shift artifacts.

  • Patent number: 6288540
    Abstract: A technique for MRI or the like employs optimized orthogonal gradients. For a device having a peak physical magnetic field gradient strength G0, the gradients are optimized if, in physical space, one gradient has a value −0.5G0 while the two gradients orthogonal thereto have the value G0. That is equivalent to an optimized orthogonal gradient space in which one gradient has a value 1.5G0 while the two gradients orthogonal thereto have the value zero. The gradients are cycled over a sequence of six gradient pulses to provide enough data to calculate the diffusion tensor.

  • Patent number: 6077889
    Abstract: A light stabilizer package is disclosed. The light stabilizer package comprises a monomeric HALS having a pKa of no greater than 7, an ultraviolet light absorber and, optionally, a polymeric HALS having a pKa of less than 7. The light stabilizer package may be blended with a thermoplastic olefin to form a moldable light stable composition. An article comprising the moldable light stable composition may have an exterior surface that is at least partially coated.
