Catalytic steam gasification process with recovery and recycle of alkali metal compounds
ActiveUS20070277437A1Promote leachingLarge specific surface areaHydrogenGas modification by gas mixingCompound aAlkali metal
A high efficiency gasification process for converting carbonaceous solids to methane and apparatus for its practice are described. The process includes reacting steam and carbonaceous solids comprising ash in the presence of alkali metal catalyst in a gasification reactor to produce combustible gases and char particles comprising ash and alkali metal catalyst constituents, treating a stream of such char particles in an alkali metal catalyst recovery system to recover the catalyst constituents as alkali metal compounds, and recycling such recovered compounds. Within the alkali metal catalyst recovery system the process includes quenching the stream of char particles with water whereby such particles are cooled and fractured, dissolving soluble alkali metal catalyst constituents from the fractured solids to form a first alkali metal catalyst solution and washed solids, optionally reacting the washed solids in alkaline solution to form a second alkali metal catalyst solution, upgrading said first and optional second alkali solution to recover the alkali metal catalyst constituents as said alkali metal compounds.

Hierarchical telecommunications network with fault recovery
InactiveUS6862263B1Less equipmentLess susceptibleInterconnection arrangementsError preventionTraffic volumeDevice failure
The present invention is a telecommunications network having a hierarchical architecture which reduces the amount of equipment and processing required to recover from network failures. In an exemplary embodiment, the nodes of the network are divided into high level nodes and low level nodes. High granularity traffic is collected, routed and manipulated at high level nodes, but generally passes through low level nodes, which generally lack the capability for routing and manipulating such high granularity traffic. Equipment savings results from low level nodes lacking the capability to manipulate traffic other than traffic relevant to those nodes or nearby nodes. Each high level node pair is connected by at least three node disjoint paths of low level nodes and links. Less protection capacity is needed, as each node disjoint path is expected to handle only a portion of rerouted traffic in the event of a network equipment failure. Recovery is decentralized, and is thus faster, requires less equipment, and is less susceptible to the failure of a centralized controller than with networks using centralized recovery processing.

ActiveUS20080198955A1Limited dynamic rangeReduce distanceSite diversityPolarisation/directional diversityDistributed antenna systemComputer science
The present invention is directed to improvements for distributed antenna systems and more particularly to methods and systems for improving uplink communications. In one embodiment, Aggregation Point Noise Blocking provides for blocking or filtering the noise contributed by one or more of the branches coupled to an aggregation point that are not carrying the signal from a particular terminal. Signal activity from a given terminal on a particular branch can be identified and that information can be used to selectively block or filter the signal noise contributed by the other branches to an aggregation point. The selective blocking or filtering can also include an attenuation function to attenuate the signal and provide dynamic range smoothing. In another embodiment the signal can be regenerated to produce a signal that has a restored or very high SNR. An uplink regeneration block can be provided which demodulates the uplink signal to recover the transmitted information and then re-modulates the transmitted information to regenerate a signal at a restored or very high SNR.

Capacitive electric musical instrument vibration transducer
InactiveUS7408109B1Low costImprove fidelityElectrophonic musical instrumentsLinear/angular speed measurementParallel plateElectronic instrument
A capacitive electric musical instrument vibration transducer contains one or more parallel plate variable capacitors. Each variable capacitor contains one vibrating variable capacitor plate, an electrically conducting surface that comprises, covers, or is embedded within an acoustically emitting vibrating surface on a musical instrument (such as a drumhead or soundboard), and one fixed variable capacitor plate comprising a rigid electrically conducting surface held a fixed distance away. When the instrument is played, the vibrating surface causes vibrations directly (without using airborne sound as an intermediary) in the vibrating variable capacitor plates, thus causing time-varying voltage oscillations in the parallel plate variable capacitors reflecting the vibrational state, and therefore the sound, of the instrument. An electric circuit in the transducer converts these voltage oscillations into the same kinds of signals produced by microphones and magnetic pickups.
