Title: Toilet overflow control.
Inventor: QUINN MICHAEL C
IPC: E03D1/00
Filed: 2007-05-24
Abstract: A toilet overflow control system is provided including a secondary float chamber and secondary float. The secondary float chamber is located below the toilet water tank and behind the toilet bowl at the water level of the toilet bowl and extending upward to the bottom of the toilet water tank. A vertical rod extends upward from the secondary float and is attached to a lever on the toilet water supply valve. This allows the secondary float to turn off the water when the toilet bowl water rises above a normal level. The vertical rod is inside a tube that allows it to go through the water tank without any loss of water. The secondary float chamber is fluidically connected to the toilet bowl by a horizontal conduit located just above the toilet bowl normal water level. A rinse hose is connected to the water supply valve to allow rinse water to flow into the secondary float chamber to prevent a back flow of water into the secondary float chamber during the flush.

Title: Optimization of fact extraction using a multi-stage approach.
Inventor: AZZAM SALIHA
IPC: G06F17/27
Filed: 2007-07-20
Abstract: Facts are extracted from electronic documents by recognizing factual descriptions using a fact-word table to match to words of the electronic documents. The words of those factual descriptions may be tagged with the appropriate part of speech. More detailed analysis is then performed on those factual descriptions, rather than on the entire electronic document, and particularly to the text in the neighborhood of the fact-word matches. The analysis may involve identifying the linguistic constituents of each phrase and determining the role as either subject or object. Exclusion rules may be applied to eliminate those phrases unlikely to be part of facts, the exclusion rules being based in part on the linguistic constituents. Scoring rules may be applied to remaining phrases, and for those phrases having a score in excess of a threshold, the corresponding sentence part, whole sentence, paragraph, or other document portion may be presented as representing one or more facts.
