Abstract: A data management system and unit host applications and manage storage, finding and retrieval of typed items with support for tagging, connections, and situated queries. The data management system and unit have a content processor that receives content and processes the content to add one or more items into a particular cell, an item processor that receives one of an item to add to the cells in the storage unit and an item to update in the cells of the storage unit and a query processor that executes a query against the one or more cells in the storage unit.

Abstract: An application specification system and method have a storage unit with an XML based schema definition for an application definition language and one or more cells with each cell having one or more components that define computational and data access aspects of an application and one or more presentations. The system and method also have a web presence that performs one or more applications that is instantiated from a cell instance that has one or more components.

Abstract: A data management method to host applications and manage storage, finding and retrieval of typed items with support for tagging, connections, and situated queries is provided.

Abstract: An application specification system and method are provided. The application specification system may include a computing device having a processor wherein the processor implements an information management system having a storage unit. The storage unit may have one or more cells with each cell having one or more components wherein each component defines computational and data access aspects of an application and one or more presentations wherein each presentation defines a user interface for a particular application and wherein a web presence for performing one or more applications is instantiated from a cell with one or more components and one or more applications of the web presence are defined by the one or more components of the cell.

Abstract: Among other disclosed subject matter, a method includes detecting that a location is to be determined. The method includes selecting at least one among multiple location determination techniques based on a selection criterion. The method includes causing the location to be determined using the selected location determination technique.

Abstract: A number of devices co-located at a geographic location can broadcast and receive tokens. Tokens can be exchanged using a communication link having limited communication range. Tokens that are received by a device can be stored locally on the device and/or transmitted to a trusted service operating remotely on a network. In some implementations, the tokens can be stored with corresponding timestamps to assist a trusted service in matching or otherwise correlating the tokens with other tokens provided by other devices. The trusted service can perform an analysis on the tokens and timestamps to identify devices that were co-located at the geographic location at or around a contact time which can be defined by the timestamps. A group can be created based on results of the analysis. Users can be identified as members of the group and invited to join the group.

Abstract: Among other disclosed subject matter, a method includes obtaining, in a mobile device, power information indicating a detected power of respective signals received from multiple transmitters. The method includes determining a location of the mobile device using a formula that uses: locations of the multiple transmitters, a first function of the power information and a second function of respective locations of the multiple transmitters. The method can include recording the determined location.
