20100042166 | SPINAL FIXATION SYSTEM - A fastener assembly for a spinal fixation system that is particularly useful in treatment of pediatric and small-statured patients includes a fastener, an attachment member, and a locking member. The fastener has a lower portion for contacting a bone and an upper portion integral with the lower portion. The upper portion has two open channels. Each channel is configured and dimensioned to receive a portion of a longitudinal or connecting member along its circumference. The attachment member is positionable on the fastener and at least partially covers the channel that receives the longitudinal or connecting member. The locking member is operatively associated with the upper portion of the fastener and secures the attachment member and the longitudinal or connecting member to the fastener. | 02-18-2010 |

20090311443 | METHOD OF COATING INNER AND OUTER SURFACES OF PIPES FOR THERMAL SOLAR AND OTHER APPLICATIONS - In accordance with one embodiment of the invention, a workpiece having a smaller cross sectional dimension (e.g., diameter) is centered within a workpiece having a larger cross sectional dimension, with the workpieces being electrically connected. In this embodiment, surfaces of the two workpieces can be coated simultaneously, either with the same coating material or different coating materials. In another embodiment, holes are located along the length of an internal metal tube which functions as a gas distribution injector and anode holder. A ceramic liner may be placed inside the internal metal tube, with a conductive wire within the ceramic liner. The internal metal tube may be biased as a cathode, while the internal wire is biased as an anode. The hollow cathode effect is applied in all spaces directly adjacent to the surface or surfaces being coated. In some applications, different surfaces being coated are biased at different voltages. | 12-17-2009 |

20130346164 | PEER-TO-PEER (P2P) CURRENCY PLATFORM INCORPORATING DEMURRAGE - A method includes providing, through an agent executing on a computing platform at a data processing device, a capability to a user of the data processing device to form a group of members. Each of the members is associated with a data processing device coupled to the data processing device forming the group through Internet. The method also includes generating, through the data processing device forming the group, a currency to be distributed across the members as a value exchange token for goods and/or services within the group, and providing a capability to each member to participate in management of the currency within the group. Further, the method includes recording currency transactions within the group through a currency server, and implementing demurrage on the currency to incentivize quick spending on part of the members. The demurrage is associated with a decrease in value of the currency over time. | 12-26-2013 |
