Canonical name (CNAME) handling for global server load balancing
Canonical name (CNAME) handling is performed in a system configured for global server load balancing (GSLB), which orders IP addresses into a list based on a set of performance metrics. When the GSLB switch receives a reply from an authoritative DNS server, the GSLB switch scans the reply for CNAME records. If a CNAME record is detected and it points to a host name configured for GSLB, then a GSLB algorithm is applied to the reply. This involves identifying the host name (pointed to by the CNAME record) in the reply and applying the metrics to the list of returned IP addresses corresponding to that host name, to reorder the list to place the “best” IP address at the top. If the CNAME record in the reply points to a host name that is not configured for GSLB, then the GSLB sends the reply unaltered to the inquiring client. |

Flexible polar encoders and decoders
Modern communication systems must cope with varying channel conditions and differing throughput constraints.

System and method for production of ultra-pure hydrogen from biomass
The disclosure provides a system and method for synthesizing ultra-pure hydrogen from biomass waste. The present invention comprises a gasifier, an oils and tars filter, a steam generator, a water gas shift reactor (“WGS”), a heat-exchange two-phase water separator, a scrubber, a hydrogen separator, and fluid conduits in fluid communication with the various system components, which together convert hydrocarbon-based biomass, e.g., woodchips, into ultra-pure hydrogen gas. Fluid conduits connect the gasifier and the steam generator, separately, to the WGS, the WGS to the two-phase separator, the two-phase separator to the scrubber, and the scrubber to the hydrogen separator, which further comprises an outlet port through which hydrogen gas may flow free of carbon monoxide. The hydrogen may flow to a device that utilizes hydrogen to generate energy, such as a hydrogen fuel cell or to an internal combustion engine. |

Electrochemical hydrogen sensor for global/local hydrogen starvation detection in PEM fuel cells
A fuel cell stack hydrogen starvation detection device, a fuel cell system and a method of operating a fuel cell stack to protect it from hydrogen starvation conditions. In one particular form, the fuel cell system includes a stack of fuel cells, a controller and a detection device made up of one or more sensors that can compare a reference signal corresponding to the presence of substantially pure hydrogen to a signal that corresponds to a local hydrogen value within a single fuel cell within the stack or across multiple fuel cells within the stack. In this way, the detection device promptly provides indicia of a hydrogen starvation condition within the cell or stack without the need for conventional cell voltage monitoring. The detected hydrogen starvation condition may be presented as a warning signal to alert a user that such a condition may be present, as well as to the controller for modification of the stack operation. |
