Abstract: A method and system for implementing URL scheme proxies. Embodiments of the invention allow URL schemes that are not natively supported by a computer to be supported via proxy, e.g., using a URL scheme that is native to the computer to forward the non-native transport. More specifically, embodiments of the invention allow a first computer system to support a first URL scheme by encapsulating its transport information into another URL scheme that is natively supported by the first computer. The encapsulated information is then forwarded to a second computer system or server which can provide support for the first URL scheme transport. For instance, if the first computer supports http but does not support ftp, then an ftp transport can be encapsulated inside an http transport and then forwarded to an ftp server which can then extract and process the ftp transport. The ftp response can be handled in an analogous fashion. The invention increases the native URL scheme capabilities of a computer system by proxy.

Abstract: A computer system that attempts to establish an alternative network link upon failing to establish a requested network link is described. The computer system may encounter conditions where access to numerous networks, in particular wireless networks, is not available. Rather than only providing an error message to the user upon a failed attempt to establish the requested network link, the computer system determines whether the user has designated an alternative network link in case the requested network link cannot be established, whereas the alternative network link is selected from the plurality of network links that the computer system is configured to support. If an alternative network link has been designated, the computer system attempts to establish the alternative network link. Hence, the user experience is made smooth and uneventful when the requested network link cannot be established.

Abstract: A method and system utilizing both (x, y) coordinate (“spatial”) stroke data and associated pressure information for improved handwriting recognition. The method and system can also be applied to all types of handwriting-based data entry applications and also to user authentication. The digitizer pad used in the computer system gives both spatial information and associated pressure data when a stroke is being drawn thereon, e.g., by a stylus. Pressure information can be used to differentiate between different character sets, e.g., upper case and lower case characters for certain alphabetic characters. The spatial stroke data then identifies the particular character. The pressure information can also be used to adjust any display attribute, such as character font size, font selection, color, italic, bold, underline, shadow, language, etc. The associated pressure information can also be used for recognizing a signature. In this case, a user is allowed to sign a name on the digitizer pad.

Abstract: A method and a system for navigating a display screen to search for a desired item of information stored in an electronic device.

A user may commence a navigation session by touching the display screen in a non active area or by clicking on a specifically designated icon to activate the user interface. During the navigation session, the display screen is zoomed-out and a magnifying area may appear on the display screen. The user interface enables the user to scroll the zoomed-out display screen by dragging the magnifying area towards an edge of the display screen to find a desired item of information. The display screen may be a display screen of a digital device (e.g., portable computer, personal computer, a cellular telephone, a digital watch, etc). The user may terminate a navigation session by removing the pointer from the display screen.

Abstract: A method and system providing automatic collection and updating of application usage on large number of electronic devices without user intervention. The electronic devices may be palm-sized computer systems, personal digital assistants (PDAs), or wireless telephones. On an electronic device, application usage statistics, for example, the number of times a user uses an application, are gathered and stored. Once gathered and stored, the usage statistics are transferred to a host computer, and subsequently to a server (alternatively, the electronic device can send the gathered statistics directly to a server). The server tabulates usage statistics gathered from a plurality of electronic devices and publishes the results. The users of the electronic devices that gather usage statistics can be compensated in a variety of ways (e.g., monetary, chances in a raffle, discounts on purchases etc.).

Abstract: A method and apparatus for authenticating and authorizing online transactions. An authentication cookie is transmitted to a client system. The authentication cookie includes a user encryption key and an encrypted buffer that contains user identification data and a profile code. Subsequent requests for the particular service use the authentication cookie to generate a query that includes the encrypted buffer and user identification data entered by the user. Portions of the query are encrypted using the user encryption key. Queries received at each authentication and authorization server are authenticated by reconstructing the user encryption key using information transmitted in the clear and decrypting the query using both the reconstructed user encryption key and the secret key. The user identification data entered by the user is then compared with the user identification data in the encrypted buffer for further authentication. The profile code is analyzed for determining authorization.

Abstract: A single ended synchronization agent which communicates with a single endpoint. Responsive to instructions from a synchronization manager, a single ended synchronization agent transfers information between its endpoint and a common synchronization engine. Endpoints may include databases, hand held computers, communication links and the like. These novel single ended agent programs in cooperation with a common synchronization engine are able to synchronize databases. The agent programs need not implement synchronization logic and agent programs are required to understand only a single database. These aspects of the single ended agent programs greatly simplify the design, construction and maintenance of this software when compared with the prior art.

Abstract: The present invention is drawn to a method and/or a system for recovering from an OS crash caused by unsuccessful event notification to a client that is typically a third party program. After the recovery from such crash, the present invention is also drawn to a method and/or a system for avoiding such OS crash in the future. Specifically, the crash recovery steps include recording the current position of the client on a client list kept by the OS. The current position is recorded in a memory location impervious to OS crashes and system reset. Once the OS crash and reboot are completed, the persistently stored current position is accessed to identified the client that was notified prior to the OS crash. The identified client is designated as an errant client, namely a client whose notification might trigger an OS crash. In turn, the errant client is removed from either the notification list or the computer system in order to prevent the client from triggering any future OS crash.
