Abstract: Some implementations provide low power reduced sampling of global positioning system (GPS) locations. A server may be configured to assist a mobile device in determining a location from a plurality of GPS signal samples and corresponding time stamps provided by the mobile device, such as by identifying a set of possible reference locations, which may be used to calculate a location of the mobile device. In another example, the mobile device may sample GPS signals using a GPS receiver, compress the samples, and provide the compressed samples to the server for processing.

Abstract: The effective use of weak GPS signals that are present in various environments enables an electronic device to pinpoint its location in such environments. The electronic device uses an antenna to perform sequential scanning in multiple directions for global positioning system (GPS) signals. The electronic device further analyzes GPS signals obtained from scanning the multiple directions to determine a number of acquired GPS satellites that provided the GPS signals. The GPS signals include code phases of the acquired GPS satellites. The electronic device then computes a location of the electronic device based on the code phases of the acquired GPS satellites when the number of acquired GPS satellites meets a threshold.

Abstract: Relational data is extracted from spreadsheets. A relational data extraction program is synthesized, where this synthesized program is consistent with examples of relational data associated with a spreadsheet. The synthesized program is executed on the spreadsheet, which extracts a set of tuples therefrom that is consistent with these examples, and generates a table that includes the extracted set of tuples. A program is received that specifies a set of constraints defining relational data to be extracted from a spreadsheet, where this set of constraints includes cell constraints and spatial constraints. The received program is executed on the spreadsheet, which extracts a set of tuples therefrom that is consistent with the set of constraints, and generates a table that includes the extracted set of tuples.
