Abstract: Examples herein involve detection of entities in unstructured data. Terms are extracted from unstructured data. Entities scores for the terms are calculated using information from a name probability source, a known entity database, and historical context information. The entity scores indicate a probability that the respective terms refer to entities. The presence of detected entities are indicated based on the entity scores.

Abstract: The invention described is a pipe guard that prevents unwanted debris from entering a pipe while still allowing the flow of water. The pipe guard includes braces connecting a mounting flange on the outside of the pipe to a plate within the pipe having a plurality of holes. A bracket extends from one brace to the other between the flange and plate to provide additional support and rigidity to the pipe guard as well as acting as a handle that can be grasped by a worker to remove the pipe guard and material that may build up on the plate. The pipe guard is secured within the pipe by fasteners that extend through threaded holes in the braces and partially embed into the interior wall of the pipe. Accordingly, the pipe guard cannot be pulled free from or knocked loose from the pipe without loosening the screws.

Abstract: A system to design, create integrate and operate online communities uses web-based participation technologies. Any content can have attributes that make it appear as any type of content. With this uniform content architecture, all user-generated content is treated as a post (or, more generally, a submission), and there is no need for a participant to author multiple entries for separate uses. Preferably, content created or otherwise associated with a particular author is intrinsically tied to the author via the author's profile. At each point of participation, the content is associated with the individual, which allows the system to build and maintain a rich “living” profile for each community member. Using this approach, the system can build and enable querying of so-called “social aggregations,” which are data sets that describe a relationship among one or more author attributes and one or more content attributes.

Abstract: A system that enables enterprises to design, create integrate and operate online communities. The system operates as an on-demand hosted platform (software-as-a-service) that provides a secure and reliable architecture on which enterprises can safely and securely develop, execute and manage their online communities. The platform combines a wide range of web-based participation technologies (e.g., blogs, wikis, discussion groups, social networking, podcasts, RSS, tagging, photos, videos, mapping, and the like). Any content can have attributes that make it appear as any type of content. With this uniform content architecture, all user-generated content is treated as a post (or, more generally, a submission), and there is no need for a participant to author multiple entries for separate uses. Preferably, all content created or otherwise associated with a particular author is intrinsically tied or “linked” to the author via the author's profile.

Abstract: Apparatus controls a power converter 34 to interchange power between first and second electric sources, 30 and 32. Typically the first source 30 is a standard utility bus and the second source 32 is a storage battery. A controller generates control signals in response to the utility bus voltage, to a command specifying the required power interchange and to a feedback signal indicative of the actual power being interchanged. These signals control the power converter 34 to produce the required power interchange.

Abstract: A high power switching circuit which utilizes a four-terminal Darlington transistor block to improve switching speed, particularly in rapid turn-off. Two independent reverse drive currents are utilized during turn off in order to expel the minority carriers of the Darlington pair at their own charge sweep-out rate. The reverse drive current may be provided by a current transformer, the secondary of which is tapped to the base terminal of the power stage of the Darlington block. In one application, the switching circuit is used in each power switching element in a chopper-inverter drive of an electric vehicle propulsion system.
