Abstract: Many indoor location services do not require precise knowledge of the position of a mobile device, but simply whether a mobile device is within a particular zone of an indoor area. Existing signals in an indoor space may provide enough information to distinguish between different zones of an indoor area, allowing a server to provide indoor location services without requiring the installation of new signal sources in the indoor area.

Abstract: Systems and methods are provided for implementing a browsing application that allows users to navigate image-based content. Images and associated descriptive attributes describing the images are stored in a database. The user may select an item of interest and an example-based proximity search function may be executed to search for similar images. Images having common descriptive attributes may be grouped together and displayed. A web browser may be implemented and users may select reduced-size images of previously viewed web pages in order to access the web page.
