238results about How to "Maintain validity" patented technology

This invention is a network that is defined by its novel approach to privacy, security and freedom for its users. Privacy by allowing access anonymously, security by encrypting and obfuscating resources and freedom by allowing users to anonymously and irrefutably be seen as genuine individuals on the network and to communicate with other users with total security and to securely access resources that are both their own and those that are shared by others with them. Further, this invention comprises a system of self healing data, secure messaging and a voting system to allow users to dictate the direction of development of the network, whereby adoption or denial of proposed add-ons to the network will be decided. System incompatibilities and security breaches on networks and the Internet are addressed by this invention where disparity and tangents of development have had an undue influence. The functional mechanisms that this invention provides will restore open communications and worry-free access in a manner that is very difficult to infect with viruses or cripple through denial of service attacks and spam messaging, plus, it will provide a foundation where vendor lock-in need not be an issue.

A graceful shutdown technique modifies a routing protocol to allow an intermediate node, such as a router, to announce to its peer routers (peers) its intention to be gracefully shutdown and removed from service in a network. By announcing its intention to be removed from service, the shutdown router closes (terminates) all connections with its peers and all original routes advertised on those connections are removed (withdrawn) from service. According to the inventive technique, the shutdown router may continue forwarding packets over the network for a “grace” period of time, i.e., the router maintains the validity of those original routes so that packets mapped to the routes are not dropped (at least during the grace period). The grace period also allows backup paths to be propagated to each peer and put into service prior to a final withdrawal of the shutdown router's paths from a forwarding information base of the peer. Thus, the grace period enables the network to continue using the shutdown router as a next hop as it re-converges to use the alternate, backup paths.

An automatic upgrading method in which, when software is downloaded and upgraded to change a specification of a software defined radio system on a vehicular system, convenience to a user who receives services using wireless communication is not reduced and error operations of the vehicular system is inhibited, is provided. A state in which a vehicle is not used is the most appropriate for the upgrade. It is determined whether a key is removed. When the key is removed, the download is executed using wireless communications. After that, a software defined radio system and a car navigation system are stopped. The upgrade and test operation are executed. When the test result is good, the software defined radio system and the car navigation system are restarted.

A method is provided for creating and maintaining the validity of a cache group including one or more cache elements. Each of the cache elements corresponds to a different address space in a virtual memory of a computer system. Each of the cache elements include one or more caches that store mappings from virtual addresses to data or values that are functions of or dependent upon physical addresses that correspond to the virtual addresses. When there is an address space switch from a first address space to a second address space, the cache group is searched to find the cache element corresponding to the second address space, and that found cache element is made the current cache element for virtual memory access through the cache element. Changes in the page tables are also detected and reflected in the caches of the cache group to maintain the caches up-to-date.

A technique for making post-signing modifications to a digitally-signed software application without invalidating the signature can be used to enhance a user experience when downloading the software application. An extension module extends the length of a signature section at the end of an executable file for the digitally-signed software application to form a storage section. A header adjustment module adjusts the header to indicate size of the storage section appended at the end of the executable file. A data insertion module inserts post-signing data into the storage section, and the validity of the digital signature is maintained without requiring the file to be re-signed after insertion of the post-signing data. Thus, a software vendor can add into the software user-specific data after the file has been signed, while still maintaining the signature's validity, so the software can be downloaded with minimal interruption to the user.

A disc braking system of a vehicle determines the actual temperature of a brake rotor. The disc braking system compares the actual temperature of the brake rotor to a critical temperature of the brake rotor. The critical temperature of the brake rotor is a temperature above which damage and / or warping to the brake rotor may occur. The disc braking system applies a corrective measure to prevent damage to the brake rotor when the actual temperature of the brake rotor is greater than the critical temperature of the brake rotor. The corrective measure may include, but is not limited to: displaying a warning, adjusting a fraction control system of the vehicle, scheduling maintenance for the vehicle.
