Patent number: 7092165Abstract: Microlens arrays (105) having high focusing efficiencies are provided. The high focusing efficiencies are achieved by accurately producing the individual microlenses making up the array at high fill factors. Arrays of positive microlenses are produced by forming a master having a concave surface-relief pattern (101) in a positive photoresist (21) using direct laser writing. Through this approach, the problems associated with the convolution of a finite laser beam with a desired profile for a microlens are overcome. The microlens arrays of the invention have focusing efficiencies of at least 75%.Type: GrantFiled: December 17, 2004Date of Patent: August 15, 2006Assignee: Corning IncorporatedInventors: G.

Patent number: 7088099Abstract: Spatial encoding in magnetic resonance imaging (MRI) techniques is achieved by sampling the signal as a function of time in the presence of magnetic field gradients, e.g., X, Y, and Z gradients. The gradient magnets have in the past been assumed to generate a linear gradient, and typical image reconstruction techniques have relied upon this assumption. However, to achieve high speed performance, gradient magnets often sacrifice linearity for speed. This non-linearity, in turn, results in distorted images, the distortion often being sufficiently large to compromise the usefulness of MRI images for stereotaxy or longitudinal studies, where precise volumetric information is required. The disclosure provides practical methods for correcting distorted images resulting from such non-linearity in the gradient fields, as well as distortions resulting from translational, rotational, and/or winding/design errors in the field generating devices.Type: GrantFiled: December 23, 2003Date of Patent: August 8, 2006Assignee: The University of QueenslandInventors: David M. Doddrell, Huawei Zhao

Patent number: 6974786Abstract: Isopipes for use in making sheet glass by a fusion process are provided which exhibit reduced sag. The isopipes are composed of a zircon refractory which has a mean creep rate (MCR) at 1180° C. and 250 psi and a 95 percent confidence band (CB) for said mean creep rate such that the CB to MCR ratio is less than 0.5, the MCR and the CB both being determined using a power law model. The zircon refractory can contain titania (TiO2) at a concentration greater than 0.2 wt. % and less than 0.4 wt. %. A concentration of titania in this range causes the zircon refractory to exhibit a lower mean creep rate than zircon refractories previously used to make isopipes. In addition, the variation in mean creep rate is also reduced which reduces the chances that the zircon refractory of a particular isopipe will have an abnormally high creep rate and thus exhibit unacceptable sag prematurely.Type: GrantFiled: May 29, 2003Date of Patent: December 13, 2005Assignee: Corning IncorporatedInventors: John D. Helfinstine, Daniel J. Liebner, John L. Martin, Dean V. Neubauer, William R. Powell

Patent number: 6938396Abstract: Containers (19) are provided for packaging flexible substrates (13) such as the glass substrates used in the manufacture of liquid crystal displays. The containers include arc-shaped grooves (25) which apply an elastic strain to the substrates. The elastic strain stiffens the substrates and thus reduces the likelihood of damage to the substrates as a result of vibration during transport or sagging when held horizontally. Through the use of such grooves, dense packaging of large, thin substrates is achieved.Type: GrantFiled: December 20, 2002Date of Patent: September 6, 2005Assignee: Corning IncorporatedInventor: Fumio Okamoto

Patent number: 6896646Abstract: Pulling rolls (13) for glass ribbons (11) are provided. The rolls include a shaft (17), a plurality of heat-resistant discs (15) mounted on the shaft in face-to-face contact, and a pair of fittings (25 or 25,31) affixed to the shaft which apply an axial compressive force to the discs. The axial compressive force gives the portions (27) of the roll surface (33) which contact the glass ribbon during use a Shore D hardness at room temperature of between 30 and 55. The rolls achieve a long service life without applying excessive force to the glass ribbon or generating high levels of particulate contamination.Type: GrantFiled: March 20, 2003Date of Patent: May 24, 2005Assignee: Corning IncorporatedInventors: David S.

Patent number: RE39460Abstract: Asymmetric, compact superconducting magnets for magnetic resonance imaging are provided. The magnets have a homogeneous region (the “dsv”) which can be located close to one end of the magnet so as to reduce the sensation of claustrophobia experienced by patients undergoing MRI procedures. The magnets can be designed using a hybrid process in which current density analysis is performed to obtain an initial coil configuration which is then refined using non-linear optimization techniques to obtain a final coil configuration. The hybrid method can incorporate various constraints, including, the location and size of the dsv, the uniformity and strength of the B0 field, stray field strengths outside of the superconducting magnet, and field strengths within the magnet's coils. The hybrid technique can also be used to design compact symmetric superconducting magnets.Type: GrantFiled: October 30, 2002Date of Patent: January 9, 2007Assignee: NMR Holdings No. 2 Pty LimitedInventors: Stuart Crozier, David M.
