Abstract: Roofing shingles are disclosed that are capable of self-adhering to a roof deck or underlayment and/or other roofing shingles and that require few or no mechanical fasteners to remain attached to the roof. By appropriate positioning of sealant lines on the shingle, direct adhesion between the shingle and the roof deck or underlayment and/or other roofing shingles can be achieved. If the shingle is laminated, the layers may be mechanically attached with indentations in the common bond area. The nail zone of the shingle may be visually indicated with fines and/or one or more paint lines. A roofing system comprising a plurality of courses of the shingles is also disclosed.

Abstract: Technologies are described herein for providing dynamic natural language interactions between a user and a computing device. In one aspect, a computing device managing a conversation with a user is enhanced with the identification and management of one or more topics. Using techniques described herein, the computing device can focus on one or more topics, shift between topics and/or introduce new topics. Techniques disclosed herein may also manage and process interruptions that may be introduced during a conversation. Dynamic access of contextual information may assist in the generation of contextually-relevant statements, and the contextual information may be used to balance priorities between various topics. Each topic may also have an associated decay rate so that the lifespan of individual topics may track realistic scenarios. In addition, the priorities of individual topics may be dynamically adjusted so topics may track events created by a user and a computing device.

Abstract: In a ventilating hood generally for use in conjunction with a heating apparatus, such as a cooker, a housing incorporates both a diverter and a rear support, the two of which join to segregate the incoming air through a supply conduit from the outgoing air traversing through a support arranged filter and into an exhaust outlet. The front wall of the housing, which is spaced from the lower end of the diverter, incorporates a slightly upwardly inclined deflector, which directs substantially all of the air incoming to the hood upwardly and rearwardly directly towards for movement through the filter, and out of the exhaust outlet, and since the air is generally unencumbered by any structure in the path of its flow, it moves in a rather parallel course with the arranged diverter, and rapidly exits carrying the entrained fumes therewith significantly reducing the BTU requirements for operation of this hood.
