Abstract: Location mapping and navigation user interfaces may be generated and presented via mobile computing devices. A mobile device may detect its location and orientation using internal systems, and may capture image data using a device camera. The mobile device also may retrieve map information from a map server corresponding to the current location of the device. Using the image data captured at the device, the current location data, and the corresponding local map information, the mobile device may determine or update a current orientation reading for the device. Location errors and updated location data also may be determined for the device, and a map user interface may be generated and displayed on the mobile device using the updated device orientation and/or location data.

Abstract: This invention relates to the preparation of N-(phosphonomethyl)glycine (“glyphosate”) from N-(phosphonomethyl)iminodiacetic acid (“PMIDA”), and more particularly to methods for control of the conversion of PMIDA, for the identification of reaction end points relating to PMIDA conversion and the preparation of glyphosate products having controlled PMIDA content.

Abstract: A glass fiber duct board has longitudinally extending, spaced-apart grooves in a major surface that facilitate the folding of the duct board into an air duct. The major surface, including the grooves, is coated with a polymeric latex coating to encapsulate glass fibers and dust within the surface of the duct board. The polymeric latex coating is applied to the surfaces of the grooves as a foam by application nozzles located downstream of groove cutting tools. The polymeric latex coating applied by the nozzles is distributed over the surfaces of the grooves and set to a predetermined thickness by wiper blades, located downstream of the nozzles, which have edge configurations complementary to the transverse configurations of the grooves being coated.

Abstract: The reinforcing wires in a fibrous duct are inserted by simultaneously piercing opposite sides of the duct with elongated piercing means mounted on a reciprocally movable frame. The piercing means may be the reinforcing wires themselves or may be separate structure, such as tubes, which can function as guides for the insertion of the wire before they are withdrawn.

Abstract: Insulation board feeding apparatus feeds successive boards from a pallet stack to a grooving machine to make pre-formed duct sections. The apparatus includes a cable driven elevator assembly, a reciprocating transfer carriage with a plurality of pivotable board-engaging fingers which is reciprocated by an air cylinder, and a guide assembly comprised of two non-driven rollers. The machine of the present invention is simpler, more reliable and less expensive to manufacture than its predecessors.
