Title: Method of surface oxidizing zirconium and zirconium alloys and resulting product
Inventor: HINES GARY L
IPC: A61F2/36
Filed: 2002-07-19
Abstract: A coating of blue-black oxidized zirconium of uniform and controlled thickne ss on a zirconium or zirconium alloy material is accomplished through the use o f a single phase crystalline material substrate having an altered surface roughness. An oxidized zirconium coating of uniform and controlled thickness is especially useful on orthopedic implants of zirconium or zirconium-based alloys to provide low friction, highly wear resistant surfaces on artificial joints, such as, but not limited to, hip joints, knee joints, shoulders, elbows, and spinal implants. The uniformly thick oxidized zirconium surface of controlled depth on prostheses provide a barrier against implant corrosion caused by ionization of the metal prostheses. The invention is also useful i n non-articulating implant devices such as bone plates, bone screws, etc.</SDO AB>

Title: Packer with metal sealing element
Inventor: HIRTH DAVID EUGENE
IPC: E21B33/12
Filed: 2004-05-12
Abstract: A packer, and operation of the same, which forms elastomeric seals and non-elastomeric seals. The packer may be constructed from a non-elastomeric tubular core having a frustoconical shaped inner diameter. The outer diameter of the core may be substantially smooth and carry one or more elastomeric sealing elements. The packer is set by causing the diametrical expansion of the tubular core.  The construction of the tubular core is preferably such that its diametrical expansion causes the formation of radial raised portions (upsets) on the outer surface.  These raised portions form the non-elastomeric seals and also prevent extrusion of the elastomeric sealing elements.

Title: Detection of single nucleotide polymorphisms
Inventor: ECKHARDT ALLEN E
IPC: C12Q1/68
Filed: 2002-05-31
Abstract: A method determining the presence or absence of a single nucleotide polymorphism at a SNP site in a nucleic acid target. Capture probes are designed, each of which has a different SNP base and a sequence of probe bas es on each side of the SNP base. The probe bases are complementary to the corresponding target sequence adjacent to the SNP site. Each capture probe i s immobilized on a different electrode having a non-conductive outer layer on a conductive working surface of a substrate. The extent of hybridization betwe en each capture probe and the nucleic acid target is detected by detecting the oxidation-reduction reaction at each electrode, utilizing a transition metal complex. These differences in the oxidation rates at the different electrode s are used to determine whether the selected nucleic acid target has a single nucleotide polymorphism at the selected SNP site.

Title: Dynamic pilot filter bandwidth estimation
Inventor: PATEL SHIMMAN
IPC: H04B1/707
Filed: 2002-09-13
Abstract: A method and apparatus to dynamically adjust parameters of a filter for a pilot signal. An incoming signal containing a pilot signal is filtered using non-identical filters, and the magnitudes of the filtered signals are compared to estimate a bandwidth of the pilot signal. Noise in the incoming signal may also be estimated, preferably from a portion of the incoming signal not expected to contain the pilot signal. Based on the comparison of the filtered signal magnitudes, which may be compensated to remove the noise contribution, the parameters of a filter applied to the incoming signal to isolate the pilot signal are varied. The parameters may vary the bandwidth of a pilot signal filter. The non-identical filters used in the pilot signal bandwidth estimation may be IIR or FIR filters having different passbands, or may be a correlation of the incoming signal with sinusoids of different frequencies.
