| 20100008188 | SYSTEM AND METHOD FOR ACQUIRING INFORMATION DURING UNDERGROUND DRILLING OPERATIONS - A preferred method for acquiring information during an underground drilling operation includes providing a sensing device capable of acquiring information concerning the underground drilling operation from a down-hole location on a selective basis in response to an input from the surface, and drilling for a first period of time. The preferred method also includes sending the input to the sensing device after drilling for the first period of time, and drilling during a second period of time while acquiring the information using the sensing device. | 01-14-2010 |

| 20080261159 | Electrophoretic Display Device - An electrophoretic display device includes a multiplicity of individual reservoirs containing a display medium between conductive substrates, at least one of which is transparent, wherein the display medium includes one or more set of colored particles in a dielectric fluid, and wherein the multiplicity of individual reservoirs are defined by a unitary grid whose walls segregate the reservoirs. The gird may be formed via photolithography or from a master stamp derived from a mold of the grid pattern. | 10-23-2008 |
| 20090051646 | Flexible Electrophoretic-Type Display - An electrophoretic-type display device including an array of microcells, where each microcell is formed by a microwell containing a quantity of ink and a polymer-based membrane connected to upper edges of the microwell. The membrane is formed by curing an aqueous or hydroalcoholic sealing solution that is overcoated on the ink-filled microwells. The ink includes an isoparaffinic-based or oil-based suspension fluid, and the peripheral side walls of the microwell have a surface energy in the range of 20 to 30 mN/m. The microwell material serves two purposes: to prevent displacement (floating) of the relatively light ink solution above the relatively heavy sealing solution, and to facilitate reliable attachment between the polymer membrane and microwell walls during subsequent curing. | 02-26-2009 |
| 20100096729 | GEOMETRY AND DESIGN FOR CONFORMAL ELECTRONICS - A method of forming a three-dimensional electronic device includes forming at least one electronic device on a two-dimensional, flexible substrate, the electronic device being formed according to a three-dimensional structure, cutting the two-dimensional, flexible substrate, the cuts being located to allow the two-dimensional substrate to be shaped, the cuts having at least one stress relief feature, and shaping the two-dimensional, flexible substrate to form the three-dimensional structure, the stress relief features arranged to alleviate stress in the three-dimensional structure. A method of forming a three-dimensional electronic device includes forming at least one electronic device on a two-dimensional, flexible substrate, the electronic device being formed according to a three-dimensional structure, cutting the two-dimensional, flexible substrate, the cuts being arranged to as to increase a radius of curvature to meet a stress relief parameter when the substrate is shaped, and shaping the two-dimensional, flexible substrate to form the three-dimensional structure. A three-dimensional electronic device having an electronic device formed on a flexible substrate, the flexible substrate formed into a three-dimensional structure, wedged-shaped portions removed from the substrate to allow the substrate to be formed into the three-dimensional structure, and a stress relief feature arranged adjacent to the wedge-shaped portions. | 04-22-2010 |

| 20090174200 | Crash Attenuator - A crash attenuator for decelerating an impacting vehicle includes a first end that can be releasably secured to a vehicle, and a second end that is longitudinally spaced from the first end. The second end includes an impact member that is movable in the longitudinal direction from a pre-impact position to an impact position. At least a pair of deformable attenuator members are spaced laterally and extend longitudinally between the first and second ends. At least a portion of the attenuators are bent in a non-outboard direction when the impact member moves from the pre-impact position to the impact position. | 07-09-2009 |
| 20100243978 | GUARDRAIL ASSEMBLY, BREAKAWAY SUPPORT POST FOR A GUARDRAIL AND METHODS FOR THE ASSEMBLY AND USE THEREOF - A breakaway support post for a guardrail includes an upper post member and a lower post member. The upper and lower post members are overlapping and configured such that the upper and lower post members are non-rotatable relative to each other about an axis extending in an axial impact direction. In one embodiment, a tensile fastener extends in the axial impact direction and connects overlapping portions of the upper and lower post members. In another embodiment, a shear fastener extends transversely to the axial impact direction and is the only connection between the upper and lower post members. In another aspect, a guardrail assembly includes first and second rail sections, with a deforming member deforming the first rail section as it moves relative to the second rail section. Methods of using and assembling a guardrail assembly are also provided. | 09-30-2010 |

| 20090305045 | Preparation of Transition Metal Nanoparticles and Surfaces Modified with (CO)Polymers Synthesized by RAFT - A new, facile, general one-phase method of generating thiol-functionalized transition metal nanoparticles and surfaces modified by (co)polymers synthesized by the RAFT method is described. The method includes the steps of forming a (co)polymer in aqueous solution using the RAFT methodology, forming a colloidal transition metal precursor solution from an appropriate transition metal; adding the metal precursor solution or surface to the (co)polymer solution, adding a reducing agent into the solution to reduce the metal colloid in situ to produce the stabilized nanoparticles or surface, and isolating the stabilized nanoparticles or surface in a manner such that aggregation is minimized. The functionalized surfaces generated using these methods can further undergo planar surface modifications, such as functionalization with a variety of different chemical groups, expanding their utility and application. | 12-10-2009 |
| 20110060107 | PREPARATION OF FUNCTIONAL POLYMERS - The process of the present invention is directed toward conducting highly selective, high yield post polymerization reactions on polymers to prepare functionalized polymers. An embodiment of the present invention comprises conducting click chemistry reactions on polymers. Preferably, the polymers were prepared by controlled polymerization processes.
