Abstract: Methods and apparatuses for enabling remote access to an application program via a computer network provided. Logical elements of the application program may be determined, from which a state model of the application program may be developed. A remote access program updates the state model in accordance with user input data received from a user interface program, generates control data in accordance with the updated state model and provides the same to the application program. The state model may be updated in accordance with application data received from the application program, application representation data in accordance with the updated state model are generated and provided to the user interface program for display at, e.g., a remote client computing device. The application program may be a legacy mainframe application to which remote access is provided without the need to modify the source code of the mainframe application.

Abstract: Systems and methods for providing a connection of a client to an unmanaged service in a client-server remote access system. An unmanaged service may register at a remote access server and open a communication connection there between remote access server may be configured for providing remote access to the unmanaged service by a client. The remote access server receives keep-alive messages from the unmanaged service over the communication connection, which may serve to indicate that the unmanaged service is operational. The remote access server may a request for a client connection to the unmanaged service, after which, a terminate keep-alive message is communicated to the unmanaged service to terminate the sending of keep-alive messages from the unmanaged service in response to the request for the client connection to the unmanaged service.

Abstract: A client-side flow control mechanism for controlling the flow of messages communicated from a service to a client in a remote access system. The service, which may be a managed or unmanaged service, may communicate messages to the client where the messages include a service sequence ID (SSI). As the client processes the messages from the service, the client responds with a client sequence ID (CSI). The SSI and CSI values determine the number of messages that are in transmission queues. The service compares a difference between the current SSI and CSI to a stop window value. If the difference is greater than the stop window value, transmission of messages from the service to the client is turned OFF. The client continues to send CSI acknowledgments as it processes messages. Once the difference falls below a start window value, the transmission of messages to the client is turned ON.

Logical elements of the application program may be determined, from which a state model of the application program may be developed. A remote access program updates the state model in accordance with user input data received from a user interface program, generates control data in accordance with the updated state model and provides the same to the application program. The state model may be updated in accordance with application data received from the application program, application representation data in accordance with the updated state model are generated and provided to the user interface program for display at, e.g., a remote client computing device. The application program may be a legacy mainframe application to which remote access is provided without the need to modify the source code of the mainframe application.

Abstract: A method and system for remotely controlling a device via a computer network is provided. A client computer generates a client difference program indicative of a change of a state of the device last received from a server computer and transmits the same to the server computer. Upon receipt, the server computer executes the client difference program and determines an updated state of the device, generates control data indicative of the updated state of the device, provides the control data to the device, and generates and transmits a server difference program having encoded a difference between the state of the device and a state of the device last transmitted to the client computer. The client computer executes the server difference program for updating the state of the device last received from the server computer and for displaying the same in a human comprehensible fashion.

Abstract: A viewer fence that can be rotated from a position of privacy to a position that allows one to view what is behind the fence. The boards of the fence are rotated automatically by a motor. The motor may be controlled remotely.

Abstract: The present invention discloses a method, apparatus, and article of manufacture for a computer implemented geographic information system that enables viewing a map picture that is generated from vector-based data. Map pictures can be generated with vector-based data. Map pictures created with vector-based data can be viewed. Additionally, map pictures are comprised of map objects, such as states and cities. Map objects can be chosen to obtain additional information, for example, a different map picture. Additionally, areas of the map picture can be zoomed in on to view the areas with greater resolution or to obtain additional data about the areas. Furthermore, when a user requests to view a map picture, only the map data required to respond to the user's request is downloaded to generate a map picture. As a user makes additional requests for information, additional map data is downloaded and new map pictures generated.

Abstract: A method, system, and article of manufacture provide for an interactive geographic information system on a thin client. Geographic information may be viewed and interacted with on the thin client. The information is available while the thin client is connected or disconnected to/from a network. The thin client has functionality commonly available in a standard client including raster maps for multiple zoom levels of multiple tiles, raster zooms, selectable vector geometry, geo-referencing information for map navigation, metadata in the form of layer definitions, links to object attributes in databases, links to object reports generated by corporate web servers, uploadable, sharable redlining data, offline access, and a compact database.

Abstract: A method, apparatus, and article of manufacture determine a path on a network. A Global search is commenced for one or more Global paths on the network. Thereafter, when a turn restriction on a first node on the network exists, a hidden node that is not reachable from the first node due to the turn restriction is detected. A Local search commences from the hidden node in a reverse direction creating a Local search path. When the Local search can connect to the Global search, the Local search path is converted to a new Global path, and added as an alternative to the Global search.

Abstract: One or more embodiments of the invention provide for an interactive geographic information system on a personal digital assistant (PDA). The system enables the viewing and interaction with geographic information on a PDA. Such information is available while the PDA is connected to a network (i.e., online) and while disconnected (i.e., offline). Embodiments provide the PDA with the functionality commonly available in a standard client comprised of a complete computer system. For example, embodiments provide raster maps for multiple zoom levels, with each zoom level comprising multiple tiles allowing for “virtual roaming” across a map. One or more embodiments also provide raster zooms (by scaling existing raster tiles), selectable vector geometry (for interacting and highlighting with user objects), geo-referencing information for map navigation, meta-data in the form of layer definitions (visibility, display attributes, etc.
