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: Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Abstract: An apparatus for recycling synthetic thermoplastic waste material combining heretofore multiple stage processing steps in a single stage shredder grinder pulverizer device. The apparatus has multiple interchangeable material processing blade sets on respective effacing engageable rotating and fixed blade mounts within a cooled material infeed and blade containment enclosure with multiple vacuum outlet ports and communicating vacuum ducts to draw off and transport processed material therefrom for separation and classification, as required. Each replaceable interchangeable processing blade set includes registerable shredding and grinding blades and annular pulverizing blade sets on fixed and movable mediums for progressive processing of waste material into uniform recyclable material.

Abstract: A compound blade assembly for recycling machines that process random sized waste metals into uniform reusable material. A rotating processing blade and a fixed registerable bed blade each have interchangeable blade teeth sets of multiple blade edge surfaces for interengaging target waste material at multiple shear points by registerable intermeshing in a linear progressive repetitive process.

Abstract: A die assembly apparatus is provided with a plurality of die segments that move on guides from open to closed positions. Movement from the open to the closed positions for each die segment is along the path that extends inward toward a central axis and toward a base plate. A compression member provides a retaining force along the central axis to compress the die segments between limited surface areas at the top and bottom portions of the die segments. Molten wax is injected into an injection port so that the molten wax is first introduced into the die cavity at the bottom portion of the die cavity. Hydraulic actuators are used to move the die segments from the open to the closed positions and vice versa.
