Patent number 20090326815 is for a position fix indicator. It involves methods, systems, and apparatus, including computer program products, for presenting location information. In some implementations, a method includes: obtaining a first position measure at a mobile device indicating a geographic area where the mobile device is located, presenting a first graphical indicator on a user interface representing the geographic area; obtaining a second position measure at the mobile device, indicating a location associated with the mobile device, and within the geographic area; and presenting a second graphical indicator on the user interface representing the location within the geographic area. The inventors are Richard Williamson, Mike Matas, Christopher Blumenberg and Kim Tsinteris.

Patent number 20090325056 involves a parallel battery architecture with a shared bidirectional converter. Some embodiments provide a system that provides a power source. The power source includes a set of cells and a main power bus configured to connect the set of cells in a parallel configuration. The power source also includes a bidirectional converter configured to connect to one cell from the set of cells at a time. Finally, the power source includes a set of switches configured to switch each cell in the set of cells to one of the main power bus and the bidirectional converter. The inventors are Thomas C. Greening, William C. Athas and Jeffrey P. Ungar.

Patent number 20090326815 involves location sharing. Geographic location data is sent from a first device to a second device with a modified message to signal the presence of geographic location data associated with the message. The message can include (or attach) the geographic location data or file, or the message can include a link to a network-based resource which the second device can use to obtain the geographic location data. In some implementations, when a user of the first device views a location on a map display of the first device, a graphical user interface is presented to allow the user to select an option to share the geographic location with the second device. The second device receives geographic location data or a link from the first device which can trigger a map display on the second device showing the location of the first device and, optionally, the location of the second device. The inventors are Marcel Van Os, Scott Herz and Mike Matas.

Patent number 20090327285 involves semantic reconstruction. Determining a semantic relationship is disclosed. Source content is received. Cluster analysis is performed at least in part by using at least a portion of the source content. At least a portion of a result of the cluster analysis is used to determine the semantic relationship between two or more content elements comprising the source content. The inventors are Philip Andrew Mansfield, Michael Robert Levy, Yuri Khramov and Darryl Will Fuller.
