Modern communication systems must cope with varying channel conditions and differing throughput constraints. Polar codes despite being the first error-correcting codes with an explicit construction to achieve the symmetric capacity of memoryless channels are not currently employed against other older coding protocols such as low-density parity check (LDPC) codes as their performance at short/moderate lengths has been inferior and their decoding algorithm is serial leading to low decoding throughput. Accordingly techniques to address these issues are identified and disclosed including decoders that decode constituent codes without recursion and/or recognize classes of constituent directly decodable codes thereby increasing the decoder throughput. Flexible encoders and decoders supporting polar codes of any length up to a design maximum allow adaptive polar code systems responsive to communication link characteristics, performance, etc. whilst maximizing throughput. Further, designers are provided flexibility in implementing either hardware or software implementations.

A service management system for devices with embedded processor systems manages use of memory by programs implementing the services by assigning services to classes and limiting the number of services per class that can be loaded into memory. Classes enable achieving predictable and stable system behavior, defining the services and service classes in a manifest that is downloaded to embedded devices operating on a network, such as a cable or satellite television network, telephone or computer network, and permit a system operator, administrator, or manager to manage the operation of the embedded devices while deploying new services implemented with applications downloaded from the network when the service is requested by a user.

Security analysis and vulnerability testing results are “packaged” or “bound to” the actual software it describes. By linking the results to the software itself, downstream users of the software can access information about the software, make informed decisions about implementation of the software, and analyze the security risk across an entire system by accessing all (or most) of the reports associated with the executables running on the system and summarizing the risks identified in the reports.

A method and mechanism for automatically patching software implementations such as applications as they are installed from an external source. A patch program is run for a software implementation that is advertised as available, or is otherwise available, though not yet installed (or fully installed). The mechanism maintains the patch information for that software implementation. Whenever the software implementation is installed, the mechanism determines that the software implementation has the patch information maintained therefor. The mechanism automatically applies the patch as part of the on-demand installation process. The patch may change the files, the values of registry entries and/or the installation logic associated with the software implementation.

In one embodiment the method determines the significance of a data file using the format of the data file. The method also includes identifying a storage device and memory location of the storage device to write the data. In a software implementation, a computer system employs a filter driver and/or a device driver to identify and store data files. In another embodiment, a storage controller includes a state machine that initiates and executes firmware to determine the data file format and also the storage device location.

Disclosed is a secure telephone call management system for authenticating users of a telephone system in an institutional facility. Authentication of the users is accomplished by using a personal identification number, preferably in conjunction with speaker independent voice recognition and speaker dependent voice identification. When a user first enters the system, the user speaks his or her name which is used as a sample voice print. During each subsequent use of the system, the user is required to speak his or her name. Voice identification software is used to verify that the provided speech matches the sample voice print. The secure system includes accounting software to limit access based on funds in a user's account or other related limitations. Management software implements widespread or local changes to the system and can modify or set any number of user account parameters.

The present invention provides for distributed navigation and route guidance using networked computing devices. A computing device may host one or more navigation functional components. The location of a navigable object is sensed and communicated to associated navigation components in a communication network. The navigation components collectively provide guidance information to a navigable object controller. A navigable object controller directs the movement of an navigable object using guidance information to keep it on a specified route. The navigable object controller interacts with the distributed navigation system through an interface, which provides the appropriate presentation of guidance information and functions for the particular type of navigable object controller (e.g., human-machine interface, or system to system). The present invention provides the structures and methods for a flexible navigation and guidance system supporting a variety of network capabilities and computing devices using the same software implementation.

A computer-implemented method for generating a risk assessment regarding a software implementation project includes accessing a previously specified importance value and maximum score for each of a multiple of risk factors. The importance value for each risk factor reflects experience of an implementing entity regarding the extent to which the factor may negatively impact a software implementation project if the factor is not adequately addressed, the importance value and maximum score for each factor being multiplied to define a potential weighted score for the factor. An actual score for a particular software implementation project is received for each factor based on an analysis specific to the particular project. An actual weighted score for the particular project is generated for each factor by multiplying the importance value and actual score for the factor, and a relationship between the potential weighted score and actual weighted score for each factor. A risk level for the particular project is assigned to each factor according to the relationship between the potential weighted score and the actual weighted score for the factor. The risk level for each factor represents an assessment regarding the extent to which the factor may negatively impact the particular project if the factor is not adequately addressed. A risk assessment is generated for the particular project including one or more of the assigned risk levels for the particular project for one or more corresponding factors.

Hardware assisted transactional memory system with open nested transactions. Some embodiments described herein implement a system whereby hardware acceleration of transactions can be accomplished by implementing open nested transaction in hardware which respect software locks such that a top level transaction can be implemented in software, and thus not be limited by hardware constraints typical when using hardware transactional memory systems.

A framework is provided that enables data mining algorithms to be plugged into it without any change to algorithm software implementations, while still providing all the standard data mining tasks. It may be implemented by the data source provider. It also then allows for the complete separation of data storage and algorithms. When the user initiates a mining session and picks an algorithm for build task or a model for an apply or test task, the framework may become responsible for preparing a set of “prompts” to the user asking him to provide some expression which is specific to the particular kind of data the user is working with.

A dial keypad is provided for use with a mobile device having a keyboard. The keypad has a push-through, hinge-spring design that activates only one of two keyboard keys underlying a dial key and allows backlighting transmissivity. A translucent material can be used to allow the keyboard key backlighting to be coupled through to a top dial key. The keypad creates an aesthetically balanced dial keypad arrangement over a QWERTY keyboard. A preferable mechanical implementation allows backlighting and has an offset contact and spring design to activate one of the two underlying keys. This activation simplifies the software implementation for executing the dial number since the signal is coming from one address rather than having to make a determination of whether it is coming from one or two addresses. Moreover, the resulting dial key press has a standard single click feel.

Disclosed are techniques for performing an antivirus task in a mobile wireless device running an embedded operating system. In one embodiment, calls intended for an application programming interface (API) function code is redirected to an antivirus function code. The redirection to the antivirus function code may be performed by modifying a kernel structure to point to a modified entry list instead of an API entry list. The redirection to the antivirus function code may also be performed by modifying the API function code to allow the antivirus function code to execute before the API function code. The kernel structure or the API function code may be properly restored back to its original form. Software implementations of these techniques may be readily loaded and unloaded, and may not require re-installation of the embedded operating system.

Systems and methods are disclosed, especially designed for very compact hardware implementations, to generate random number strings with a high level of entropy at maximum speed. For immediate deployment of software implementations, certain permutations have been introduced to maintain the same level of unpredictability which is more amenable to hi-level software programming, with a small time loss on hardware execution; typically when hardware devices communicate with software implementations. Particular attention has been paid to maintain maximum correlation immunity, and to maximize non-linearity of the output sequence. Good stream ciphers are based on random generators which have a large number of secured internal binary variables, which lead to the page synchronized stream ciphering. The method for parsed page synchronization which is presented is especially valuable for Internet applications, where occasionally frame sequences are often mixed. The large number of internal variables with fast diffusion of individual bits wherein the masked message is fed back into the machine variables is potentially ideal for message authentication procedures.

Methods, systems and computer program products (“software”) enable a virtual three-dimensional visual experience (referred to herein as “V3D”) videoconferencing and other applications, and capturing, processing and displaying of images and image streams.

Described is managing the changing of software implementations such as applications deployed to enterprise client users or machines. Precedence relationships between deployed applications are specified. To determine which applications to install for a given client, the precedence is applied to the subset of applications assigned or published to the client. At logon or machine reboot, an upgrade process evaluates the deployed applications and any upgrade relationships, setting applications for removal or installation. A user may also install an application that has been designated as optional. Also described is an application lifecycle model for replacing applications. For example, administrators can phase in upgrades as a pilot to a small group of users, roll out upgrades to a larger group, and then provide the application to all users. Upgrades may be mandatory or optional, and replaced programs may be removed and then replaced, or overlaid during installation.

Methods, software or computer programs, and apparatus for detecting viruses and mitigating their harm to computers communicating through a gateway node to another network are disclosed. Upon detection of a virus in an incoming data stream or plurality of data packets directed to a gateway device or node, the data requesting recipient is notified and provided with a plurality of pre-defined virus handling action options. If the recipient, or designated proxy, fails to select an action option, then a random selection is made. If a selection is made, then that selection, to the exclusion of other action options, is carried out. Thus, the recipient is empowered to dynamically select, as circumstances dictate and without future prejudice, the appropriate response upon detection of a particular virus. Action options may include data encryption and forwarding with recipient notification, or where email is the vector, attachment removal and location link insertion may be used. Software embodiments of the invention provide the machine readable instructions to carry out the methods according to the invention.

A fast position tolerant and economical fingerprint verification algorithm and software implementation is disclosed. The algorithm has very important advantages in comparison to existing fingerprint verification algorithms like minutia extraction or full image analysis based on a series of two dimensional fast Fourier transforms (FFT's) and two dimensional cross correlation in speed, compactness of the biocript and finger positioning for verification. It is based on a small "yardstick" pattern being moved inside the image to be verified, and when a match is found the rest of the verification process is started. The software code implements the algorithm in the most efficient way for utilization on a digital signal processor architecture. A main area of application is in fingerprint identification and verification, but it could be implemented with same success in other image verification systems like iris, eye, face etc., where two images should be compared. The algorithm is adaptive, so various false acceptance and false rejection coefficients could be utilized very easily. It also produces a very compact biocript, which leads to better memory utilization in fingerprint databases.

A multi-threaded system for data management and other computationally intensive applications. The invention takes advantage of multi-core processors to attain high performance. Multi-core processors provide high performance by executing programs in parallel. The amount of performance gained is strongly dependent on the software implementation. To take advantage of the multi-core architecture, applications should be multi-threaded. The invention provides a uniform, configurable, and a consistent multi-threaded software structure that increases performance by distribution of tasks and workload between threads and allocating threads to different processing units, so as to run programs in parallel. The uniform structure of the threads, the ease of configuring the software, and its modularity simplify execution of complex projects and expedite application development.

Context-aware systems and methods, location-aware systems and methods, context-aware vehicles and methods of operating the same, and location-aware vehicles and methods of operating the same are described. In various embodiments, a context or location service module, implemented in software, determines a vehicle context or a vehicle location based upon information that it receives from various context providers or location providers respectively. Software executing on a vehicle's computer can then cause one or more applications that are associated with a vehicle computer to be modified in a manner that changes their behavior. The behavior modification is based on the current context or location of the vehicle and thus provides a context-specific or location-specific user experience. The context or location can be ascertained through the use of one or more hierarchical tree structures that comprises individual nodes. Each node is associated with a context or location. The nodes are traversable by the vehicle's software to ascertain a more complete context or location.
