20130181880 | LOW PROFILE WIDEBAND MULTIBEAM INTEGRATED DUAL POLARIZATION ANTENNA ARRAY WITH COMPENSATED MUTUAL COUPLING - A low profile wideband multi-beam integrated dual polarization antenna array with compensated mutual coupling effect. Instead of suppressing mutual coupling with post-element-design techniques by attempting to block the reflections between elements, an element of the array is designed using its active impedance, i.e. its impedance with mutual coupling once the element is part of the array. The active impedance is determined using various simulation techniques and the element is then designed such that its impedance is shifted in order to modify its active impedance. This technique does not reduce the mutual coupling itself but instead, compensates for the mutual coupling effect and improves the return loss of the element. | 07-18-2013 |

20130232504 | METHOD AND APPARATUS FOR MANAGING PROCESSING RESOURCES IN A DISTRIBUTED PROCESSING SYSTEM - In one aspect, the present invention reduces average power consumption in a distributed processing system by concentrating an overall processing load to the minimum number of processing units required to maintain a defined level of processing redundancy. When the required number of active processing units is fewer than all available processing units, the inactive processing units may be held in a reduced-power condition. The present invention thereby maintains the defined level of processing redundancy for reallocating jobs responsive to the failure of one of the active processing units, while reducing power consumption and simplifying jobs allocation and re-allocation when expanding or shrinking the active set of processing units responsive to changing processing load. As a non-limiting example, the distributed processing system is implemented within a telecommunications network router or other apparatus having a configured set of processing cards, such as control-plane processing cards. | 09-05-2013 |
20130336117 | DISTRIBUTED PROCESSING SCHEME TO SUPPORT IEEE 1588 PTP OVER MULTIPLE PORTS SPANNING A LAG - A Precision Timing Protocol (PTP) is implemented over a Link Aggregation Group (LAG) formed by multiple ports of a network node, where PTP traffic goes through the same physical link between the network node and a peer network node on both the transmit and return paths. When the network node receives a PTP message that identifies a PTP stream from the peer network node through a given PTP-LAG port, it declares itself as an active port and the other PTP-LAG ports as standby for the PTP stream. The PTP stream is transmitted from the network node to the peer network node through the active port only, to maintain symmetry of the PTP stream's transmission paths between the network node and the peer network node. The network node processes exchanged messages of the PTP stream to perform timing synchronization with the peer network node. | 12-19-2013 |

The particles act as abrasive particles for prepping the surface to a prescribed surface roughness required for subsequent application of a coating to the surface. The method then entails coating the surface by electrically charging particles having the same chemical composition as the particles used to prep the surface. Finally, a charged-particle-entrained fluid stream is directed at high speed at the charged surface to coat the surface. The particles form both mechanical and electronic bonds with the surface. | 11-05-2015 |

20100122010 | USB SHARING SWITCH WITH AUTOMATIC SWITCHING CAPABILITIES - A USB printer sharing switch device with automatic switching capabilities is provided for multiple computers to share a USB printer. The sharing switch device transfers USB data between the computers and the printer without changing the data format. The automatic switching function is performed by hardware and firmware of the sharing switch device in cooperation with driver software on the computers. In one implementation, the sharing switch device includes multiple USB device controllers corresponding to the multiple computers, and employs multiple switches and a USB hub so that each computer is connected to its corresponding controller and the computer that is currently connected to the printer can communicate with its controller while printing. The current computer transmits a spooling finished command to its controller when spooling is finished. After receiving the spooling finished command, the sharing switch device automatically switches the printer to another computer. | 05-13-2010 |
