Title: Augmenting brightness performance of a beam-splitter in a stereoscopic display
Inventor: MERRITT JOHN O
IPC: G02B30/25
Filed: 2007-05-15
Abstract: An apparatus and method is disclosed for increasing the light output of a stereoscopic three-dimensional display system by reducing the light losses typically present when using a conventional beam-combining half-mirror, i.e. a beam splitting device (BSD). The separate outputs of two LCD monitors are optically superimposed, one for the left eye and one for the right eye of a user, in order to produce a brighter stereoscopic three-dimensional polarization for the rear and the side display. By selecting angles of linear LCD monitors or other display devices, embodiments of the invention can achieve as much as 60/60 efficiency for the display pair, according to the Fresnel laws of reflection regarding polarization. This intensity increase can provide a viewer a significantly brighter picture and allow the installation environment of the stereoscopic display to maintain higher ambient lighting conditions. Embodiments of the invention also can achieve both, a more efficient polarizer orientation, and the required mirror-image reversal in one simple step.

Title: Adaptive filtering method to remove ground roll from seismic data
Inventor: JI YING
IPC: G01V1/36
Filed: 2009-10-12
Abstract: A method for removing the contribution due to ground roll from a seismic data set comprises an M channel adaptive filter, which is configured via weights wi obtained using an adaptive algorithm based on seeking the minimum in a cost function J. The cost function includes an expansion of the measured signal d into d = dg + Δd (where: dg is ground roll contribution and Δd = dsig + dran, where dsig is the reflected signal component and dm, is a random noise component) and a corresponding expansion of the reference signal x into x = xg + Ox. The delta components are included as a normalization factor of cost function J to provide an optimal solution of the filter coefficients biased by the reflection signal. The data set is filtered using the configured filter and the ground roll contribution is attenuated, resulting in an improved data set.

Title: Improvements in sulfonated urea-thiourea formaldehyde resins
IPC: D06M15/423
Filed: 1957-04-01
Abstract: A hydrophilic thermosetting resin is produced by reacting 1 mol of urea at a temperature above 40 DEG C. and at a pH of 7 to 9 with 2-6,5 mols of a water-soluble aldehyde in the presence of ,01-,04 mols of bisulphite per mol of aldehyde, polymerizing the reaction product at a pH of 2,2-3,8 at above 40 DEG C., adjusting the pH to 7,0 to 9,0, reacting 0,3-2,5 mols of thiourea with the product, adjusting the pH to 3,5 to 5,5 and alkylating the product with 0,3-4 mols of a saturated aliphatic alcohol having 1-3 carbon atoms, and adjusting the pH to the alkaline side.  The alcohol may be added at any stage of the sequence of reactions.  The products are stable, i.e. do not deposit floc after standing for two weeks at 25 DEG C. and do not precipitate when diluted with 50 volumes of water at 25 DEG C. Suitable aldehydes are formaldehyde, acetaldehyde, propionaldehyde and glyoal.  Formaldehyde may be used as paraformaldehyde.  The preferred bisulphite is NaHSO3. Sulphites which yield bisulphite may be used.  In a typical example, methanol, formalin, urea NaHSO3 and triethanolamine were heated to 50 DEG C. and an initial pH of 8,1.  Paraformaldehyde was added with constant stirring and the mixture refluxed.  The pH was adjusted to about 3 with oxalic acid the mixture further refluxed and the pH adjusted to 7-3 with triethanolamine.  The mixture was cooled, methanol and thiourea added and the mixture stirred at 50-55 DEG C.  Oxalic acid was added to bring the pH to about 5, the mixture further heated at 50-55 DEG C. and then cooled and triethanolamine added to bring the pH to 7,5-8. "Hy-Flor" filtering aid (Registered Trade Mark) was added and the product filtered and concentrated to 80% solids.  The product was hydrophilic and stable.  The products may be applied, e.g. by pad baths or spraying to fabrics, e.g. nylon netting to impart flame-retardant and stiff, resilent finishes.  They are also said to be useful in paper-making.ALSO:Textile fabrics, particularly nylon net, are given a stiff, springy, resilient hand by applying to them, e.g. by padding or spraying, an aqueous solution of a condensate prepared from urea, thiourea, an aldehyde and a bisulphite (see Group IV(a)), and drying and curing the condensate by heating with ammonium bromide or chloride as curing catalyst.
