A coordinated network service that facilitates the design and implementation of a coordinated device network of IoT devices. The coordinated network service defines modules for individual IoT devices or coordinated devices that specify the necessary inputs to the device, the outputs from the device and communication protocols. Via an interface, user devices can select a set of IoT devices and specify how they are connected and the decision making logic associated with communication flow. The coordinated network service can then automatically generate mapping information that implements the decision making logic and provides necessary transformations for communications between the specified devices. The selected modules and mappings form a workflow for the coordinated device network. The coordinated network service can then generate executable code to implement the formed workflow in a coordinated device network.

Configuration of workflows for coordinated device environments

Export of data from an edge device to a provider network may be managed. An edge device may receive different data streams from different client devices in a client network. According to an export configuration received at the edge device, one of the data streams may be selected. A next portion of data in the data stream may be identified and the identified portion may be sent to a data stream destination in a remote network by the edge device.

Managed data export to a remote network from edge devices

In some embodiments, route information and/or location identifiers are directly encoded on a surface of a roadway. A route information service stores detailed route information that correspond with sections of a roadway and provides instructions to a road symbol application device to apply combinations of shapes to a surface of the roadway to encode the route information and/or location identifiers on the roadway. A sensor of a vehicle traversing the roadway detects the combination of symbols, decodes the combination of symbols to determine route information and/or location identifiers, and provides the route information to a control system of the vehicle for use in controlling the vehicle or displays the route information via a display of the vehicle.

Roadway surface applied encoded route information

A computer readable medium including computer readable code for causing a computer system to perform a method. The method includes receiving an application, receiving application information for the application, and determining an access privilege for the application based, in part, on the application information. The method also includes generating a deployment package for the application using the application and the access privilege, and publishing the application.

One embodiment of the present invention provides a system that facilitates moving an original method from a source class to a destination class and for constructing a corresponding forwarding method in the source class that preserves null semantics. During operation, the system translates the original method from the source class into a corresponding moved method, and then incorporates the moved method into the destination class. The system also constructs a forwarding method that invokes the moved method in the destination class. The system then replaces the original method in the source class with the forwarding method. In this way, invoking the forwarding method in the source class causes the moved method to be invoked in the destination class. While constructing the forwarding method, the system generates code that checks whether a 'source parameter' of the original method whose class matches the destination class is null. If so, the generated code executes the body of the original method. Otherwise, the generated code invokes the moved method in the destination class. The system also optimizes the generated code to produce optimized code for the forwarding method, whereby portions of the original method can possibly be optimized away.

Method and apparatus for preserving null semantics during use of a forwarding method

An intuitive graphical user interface is based upon a geographic map structure, and includes a system for controlling remote external electronic devices. In the defined graphical user interface, each space of the geographic map structure is rendered on a touch screen display as a graphic image of a geographic space. Within each space are colored cartoon-like icons called 'objects' which can be selected and manipulated by the user. Certain objects, referred to as portals, transport the user from one space to another space when Selected. Other objects, referred to as buttons, perform associated actions or functions when Selected. The graphical user interface is displayed on a hand-held display device used to control remote devices. Each remote electronic device transmits a user interface program object that defines a graphical user interface to the display device. The hand-held display devices displays the graphical user interface associated with the remote device when a user selects an icon associated with the remote device on the display device's touch screen display.

A method and apparatus for operating a local server computer of a client-server network includes a technique to receive a request from a client computer of the client-server network. A determination is made whether the request requires dynamically generated information from a servlet object of the client-server network. If so, a specified servlet object corresponding to the request may be uploaded from a remote server computer of the client-server network. The specified servlet object is then executed to obtain dynamically generated information corresponding to the request.

A program interpreter for computer programs written in a bytecode language, which uses a restricted set of data type specific bytecodes. The interpreter, prior to executing any bytecode program, executes a bytecode program verifier procedure that verifies the integrity of a specified program by identifying any bytecode instruction that would process data of the wrong type for such a bytecode and any bytecode instruction sequences in the specified program that would cause underflow or overflow of the operand stack. If the program verifier finds any instructions that violate predefined stack usage and data type usage restrictions, execution of the program by the interpreter is prevented. After pre-processing of the program by the verifier, if no program faults were found, the interpreter executes the program without performing operand stack overflow and underflow checks and without performing data type checks on operands stored in operand stack. As a result, program execution speed is greatly improved.

The present invention provides a verifier for use in conjunction with programs utilizing data type specific bytecodes for verifying the proper operation of the executable program prior to actual execution by a host processor. A verifier is provided which includes a virtual stack for temporarily storing stack information which parallels the typical stack operations required during the execution a bytecode program. The verifier also includes a stack snapshot storage structure having a snapshot directory and stack snapshot storage area for storing the state of the virtual stack at various points during program verification so as to assure proper stack manipulations by the source program. A two step source program verification process is provided for in which the source program is initially loaded into the verifier and a first pass source program evaluation is performed. During the first pass, the addresses of all source program target destinations resulting from conditional or un-conditional jumps are stored in sequential order in the stack snapshot directory. The source program is then reloaded and a verification of stack manipulations is performed using a virtual stack and the stack snapshot storage structure to verify proper stack manipulations by the source program. Upon completion, the source program may be interpreted, or compiled, or converted into another executable format as required by an individual user.

System and method for pre-verification of stack usage in bytecode program loops

A central processing unit (CPU) is provided and is coupled to a display for displaying graphic and other data in multiple overlapping windows. The CPU is further coupled to one or more input devices which permits a user to selectively position a cursor and input and manipulate data within each of the windows on the display. The windows include defined areas having window features such as text, icons and buttons corresponding to functions to be executed by the CPU. Multiple applications may be executed concurrently by the CPU such that each application is associated with one or more windows. Each display element (&ldquo;pixel&rdquo;) comprising the display is represented by multiple bits in a computer frame buffer memory coupled to the CPU. An alpha value (&agr;) is associated with the intensity of each pixel of the display, such that multiple images may be blended in accordance with a predefined formula utilizing the alpha values. By setting the alpha values appropriately, transparency may be accomplished such that data associated with underlying windows may be rendered visible to the user. Effectively, the present invention merges multiple images through alpha &ldquo;blending&rdquo; such that several images appear transparently on top of one another. The present invention, through the selective use of alpha blending, permits underlying windows to display data visible to the user through windows which are overlaid above an underlying window.

Method and apparatus for presenting information in a display system using transparent windows

A system and method for transmitting embedded applications over a network is disclosed, wherein a user of a computer-controlled network client, such as a remote control device used for controlling a network of computer-controlled home entertainment devices, or a Web browser running on a Web client, can request and receive compound documents that include embedded applications and/or data files that can only be processed (i.e., imaged or played) by handlers that are not resident on the client. In addition to embedded documents, the compound documents that are transmitted over the network can reference flat files (e.g, image, audio, or text files), and other compound documents. Whenever a client receives a compound document, the client determines whether it has access to all of the documents referenced in the compound document and, if not, requests the documents to which it does not have local access. So that the multiple documents embedded in a compound document can be simultaneously output by the client to a multimodal output device, the requestor includes a multi-tasking real-time kernel. This scheme allows a client user to download documents from a server that include embedded applications, which when executed on the client, allow the client to control the servers using commands downloaded from the servers.
