20080297417 | LIGHT WEIGHT RUGGED MICROSTRIP ELEMENT ANTENNA INCORPORATING SKELETON DIELECTRIC SPACER - Methods, systems, and apparatuses for manufacturing light weight microstrip element antennas incorporating a skeleton dielectric spacer instead of a regular solid body dielectric spacer is described. The microstrip element antenna comprises a radiator, a dielectric layer which is in the form of a skeleton rib-caged structure and a ground plane layer. Due to the skeleton rib-caged structure of the dielectric spacer, design flexibility in terms of a non-uniform variation of the effective dielectric constant across various dimensions of the dielectric layer is obtained. Additional advantages of such a dielectric spacer include a wider choice of materials from which the antenna can be made, overall light weight and low production time and machine cost due to lower cooling time of the dielectric. Further, an antenna with a skeleton dielectric spacer further has a better drying characteristics in an event of a water ingress during or post-production. | 12-04-2008 |

20090031164 | Method for Self-Diagnosing Remote I/O Enclosures with Enhanced FRU Callouts - A method, apparatus, and computer instructions for self-diagnosing remote I/O enclosures with enhanced FRU callouts. When a failure is detected on a RIO drawer, a data processing system uses the bulk power controller to provide an alternate path, rather than using the existing RIO links, to access registers on the I/O drawers. The system logs onto the bulk power controller, which provides a communications path between the data processing system and the RIO drawer. The communications path allows the data processing system to read all of the registers on the I/O drawer. The register information in the I/O drawer is then analyzed to diagnose the I/O failure. Based on the register information, the data processing system identifies a field replacement unit to repair the I/O failure. | 01-29-2009 |
