| 20090163099 | FABRIC AND METHOD OF MAKING THE SAME - A fabric for thermal management including the cooling of an object, such as a person's skin. The fabric is formed of a plurality of materials including at least one liquid transport enhancing material and at least one evaporative transport impeding material. When the fabric is in use, the transport enhancing material is located near an object to be cooled, while the evaporation impeding material is spaced away from the object. The fabric is peached so that there is an entanglement of the two materials. Peaching is performed on both sides of the fabric, but initially on the side with the transport enhancing material such that a portion of the evaporation impeding material is pulled into the fabric core. A method of making the fabric is also described. | 06-25-2009 |

| 20090074640 | SILICA REMOVAL FROM PREGNANT LEACH SOLUTIONS - The present invention relates generally to a process for removing dissolved or colloidal silica from a pregnant leach solution (“PLS”). More particularly, an exemplary embodiment of the present invention relates to a process which mixes PLS with an acid source, preferably lean electrolyte, to induce formation of colloidal silica that can then be collected and removed. Additionally, in an exemplary embodiment of the present invention, at least one silica seeding agent is added to induce formation of colloidal silica, at least one flocculant is added to induce aggregation of the colloidal silica, and a solid-liquid separation process is utilized to remove advantageous amounts or substantially all of the colloidal silica, thereby providing relief from supersaturation of dissolved silica in the metal recovery processes. | 03-19-2009 |

| 20080255557 | HIGH STRENGTH SUTURE WITH ABSORBABLE CORE AND SUTURE ANCHOR COMBINATION - A novel high tensile strength semi-absorbable composite suture with minimized non-absorbable mass. The suture has a core made from a bioabsorbable polymer. The core is covered by a braided sheath. The braided sheath is made from an absorbable yarn and a bioabsorbable yarn. The bioabsorbable yarn is made from a least one filament of a bioabsorbable polymer. The nonabsorbable yarn is made from at least one filament of ultra high molecular weight polyethylene. | 10-16-2008 |
| 20090264040 | Copolymers of Epsilon-Caprolactone and Glycolide for Melt Blown Nonwoven Applications - Copolymers exhibiting the following combinations of properties, including without limitation, ε-caprolactone in an amount ranging from about 12 to about 70 mole percent, glycolide in an amount ranging from about 30 to about 88 mole percent, crystallinity ranging from about 10 to about 50% as measured by WAXD or about 10 to about 50 J/g as measured by DSC, and an inherent viscosity ranging from about 0.5 to about 1.45 dL/g as measured in a 0.1 g/dl solution of HFIP at 25° C.; a method for melt blowing such copolymers and nonwoven constructs produced therefrom are described herein. | 10-22-2009 |
| 20090264912 | MEDICAL DEVICES HAVING DURABLE AND LUBRICIOUS POLYMERIC COATING - A medical device having a contact surface exposed repeatedly to bodily tissue is disclosed. The contact surface is coated with a silicone polymer and one or more non-silicone hydrophobic polymers. The preferred medical device is a surgical needle, and the preferred coating is a polydimethylsiloxane and polypropylene wax hydrocarbon mixture. The incorporation of the non-silicone hydrophobic polymer increases the durability of the coating on the device without sacrificing lubricity. | 10-22-2009 |

| 20110233386 | SINGLE-ELECTRON DETECTION METHOD AND APPARATUS FOR SOLID-STATE INTENSITY IMAGE SENSORS - Embodiments of the present invention include an electron counter with a charge-coupled device (CCD) register configured to transfer electrons to a Geiger-mode avalanche diode (GM-AD) array operably coupled to the output of the CCD register. At high charge levels, a nondestructive amplifier senses the charge at the CCD register output to provide an analog indication of the charge. At low charge levels, noiseless charge splitters or meters divide the charge into single-electron packets, each of which is detected by a GM-AD that provides a digital output indicating whether an electron is present. Example electron counters are particularly well suited for counting photoelectrons generated by large-format, high-speed imaging arrays because they operate with high dynamic range and high sensitivity. As a result, they can be used to image scenes over a wide range of light levels. | 09-29-2011 |
