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: An engine fuel injection apparatus forms an airtight vaporization chamber having cylindrical sidewall and a flat, solid chamber bottom. A vapor fuel discharge line in fluid communication with the inside of the chamber. A fuel inlet orifice penetrates the sidewall through which a fuel line accesses the chamber, supplying fuel. The fuel supply line inside said chamber terminates with a float level controller such that a constant level of fuel is maintained in the chamber. Submersed below a level of the fuel to be maintained by the float level controller is an atomization device formed of a hollow, perforated plate near, but not at the chamber bottom. An air intake in fluid communication with the atomization device provides air intrusion. As fuel enters the bottom of the chamber from the fuel supply line coming from a fuel pump a mixture of fuel and air results and is sent to the fuel intake manifold of the vehicle.
