Abstract:
Structured hierarchies for communicating contextual information relating to a VoIP conversation are provided. The structured hierarchies are utilized for efficient communications of various amounts and types of contextual information over a VoIP conversation channel. Information identifying at least one structured hierarchy, which will be used to carry the contextual information, is transmitted during establishment of a conversation between two VoIP enhanced devices and prior to the exchange of contextual information. The structural hierarchy is selected from a set of predefined and declared structured hierarchies. Subsequently transmitted contextual information exchanged between two VoIP enhanced devices is represented in accordance with the identified structural hierarchy. Additionally, the structural hierarchies can be extensible by the addition of more definitions to the current structural hierarchies.
Abstract:
A method and system for seamlessly integrating computing devices shadow information between computing devices. The transfer of information proceeds in accordance with user-defined preferences. While a user is interacting with an application on one computing device, the application is shadowed to another computing device. Since the information is shadowed, the user may continue interacting with the application on the other communication device at any point without first having to perform a synchronization.
Abstract:
A user-controlled cellular telephone positioning feature allows a cellular telephone user to correlate a user-specified location name with a cellular telephone location among one or more cells of a cellular telephone network. In one implementation, a cellular telephone location tagging application is stored and operated on a cellular telephone. The application obtains a cell identification string corresponding to a cell of a cellular telephone system with which cell the cellular telephone is in communication and allows the user to associate a location name and the cell identification string as location information for a selected location. Location data are maintained on a user's cellular telephone, and the user can selectively make the location information available others.
Abstract:
An integrated circuit (IC) module allows volatile data generated by applications to be stored within volatile data files in the volatile memory. A file system tracks the location of all data files as residing in either volatile memory or nonvolatile memory and facilitates access to the volatile data files in volatile memory in a similar manner to accessing nonvolatile data files in nonvolatile memory. The file system exposes a set of application program interfaces (APIs) to allow applications to access the data files. The same APIs are used to access both volatile data files and nonvolatile data files. When an application requests access to a data file, the file system initially determines whether the application is authorized to gain access to the data file. If it is, the file system next determines whether the data file resides in volatile memory or nonvolatile memory. Once the memory region is identified, the file system identifies the physical location of the data file.
Abstract:
An integrated circuit (IC) card is presented comprising an input/output (I/O) interface and a smart card development interface (SCDI), coupled to the I/O interface, to receive and identify debug frames interlaced within a normal communication flow between the IC card and a host system.
Abstract:
An integrated circuit card is presented comprising a storage device having stored thereon one or more code files and one or more data files, and control logic. The control logic implements an ICC runtime environment that executes an applet in response to a command identifying both a code file and a data file received from a host system.
Abstract:
A system for safe collection of payment by a vehicle operator from riders, the system including a multiplicity of electronic payment receipt generators, each operable by a vehicle operator, wherein each individual one of the payment receipt generators includes an electronic purse storing an amount of electronic cash, each electronic purse including an electronic cash loader operative to use some of the electronic cash to generate a payment receipt to be given by the vehicle operator to a rider, and an electronic purse control unit operative to prevent said electronic cash loader from exceeding said amount of electronic cash, thereby limiting the vehicle operator's entitlement to collect payments from riders, and an electronic cashier purse operative to increment the electronic purse of each electronic payment receipt generator by the amount of payment collected by the vehicle operator to whom the electronic payment receipt generator is assigned.
