Copy protection system for data carriers
A data payload PD is recorded on a compact disc in a format including a lead-in indicating a track start address ATOC and a subchannel P which changes state at a payload start address AP, subsequent to the track start address ATOC. Data ED recorded at the track start address ATOC includes unrecoverable data. Where the data payload PD is an audio track, an audio-only player begins to search sequentially from the track start address ATOC until the subchannel changes state, and reproduces the audio track from that point. A data player, on the other hand, begins to reproduce data from the track start address ATOC. When the unrecoverable data is read, the read operation is aborted, as it appears that the data has been corrupted. This operation cannot be easily circumvented, because it is not normally acceptable to ignore corrupt CD-ROM data. The disc may also include a second session containing an encrypted version of the data payload PD, where each sector is encrypted using a different key which is derived from a sector address by an algorithm and requires a special player program which performs the decryption. A supervisory program prevents circumvention of the copy protection. |

Thorough operation restriction
A thorough method for restricting which operations (processes) can be run by a user on a single workstation computer or by a user on a session in a multi-user environment, such as Microsoft Windows 2000 Terminal Services. By default, all applications (processes) are disallowed. Only explicitly assigned applications (processes) are allowed to run. The method entails running two software modules in user mode, one of which maintains a list of allowed processes for each user and one of which monitors new processes as they are started. When a new process is started the monitoring module sends the process ID to the list module. The list module checks the ID against its list and kills the process if it is not authorized. This way, only processes created by users are validated as apposed to validating all file I/O (processor intensive). This decreases the processing requirements. |

Common concurrency runtime
The common concurrency runtime (CCR) provides a simple and self-consistent set of concurrency primitives that developers can use to more readily split their computation into more discrete chunks that can scale better with additional processors. This set of primitives provides for very scalable applications that are well suited for the coming world of ubiquitous communication and very large scale out for the number of local processors. The CCR may be implemented as a single library in C# that implements channels with input and asynchronous output capabilities, along with an atomic test-and-input primitive. On top of this, richer derived operators (e.g., choice, join, replication, reader-writers, scatter-gather, etc.) may be encoded. Thus, existing C# may be built upon to provide the capability to concurrently issue I/O requests to remote systems while simultaneously performing other functions locally to increase the efficiency of the distributed system. Because it is based on C#, the CCR allows users to take advantage of a well-known programming model to address unique issues in a new programming environment. |

Horizontally-shared cache victims in multiple core processors
A processor includes multiple processor core units, each including a processor core and a cache memory. Victim lines evicted from a first processor core unit's cache may be stored in another processor core unit's cache, rather than written back to system memory. If the victim line is later requested by the first processor core unit, the victim line is retrieved from the other processor core unit's cache. The processor has low latency data transfers between processor core units. The processor transfers victim lines directly between processor core units' caches or utilizes a victim cache to temporarily store victim lines while searching for their destinations. The processor evaluates cache priority rules to determine whether victim lines are discarded, written back to system memory, or stored in other processor core units' caches. Cache priority rules can be based on cache coherency data, load balancing schemes, and architectural characteristics of the processor. |

Capacitor
A capacitor and a method for assembling a capacitor. A capacitor is assembled from a case, which contains an anode that is electrically coupled to the case and defines wells or slots receiving a plurality of cathode plates. A header is placed on the case. The header also supports a glass seal that insulates the lead tube and cathode lead coming from the cathode. Once assembled, the capacitor is filled with electrolyte. A weld extends around the header to secure the header to the case. A bent cathode configuration enables a plurality of cathode plates electrically coupled together from a common cathode plate. |

Method of manufacturing capacitor
One capacitor fabrication process including metal layer forming a metal layer on one surface of a substrate, dielectric layer forming a dielectric layer on the metal layer, metal foil forming a metal foil on the dielectric layer, separating the noble metal layer from the dielectric layer, and electrode layer forming an electrode layer on the second surface of the dielectric layer, wherein the second surface faces away from the first surface of the dielectric layer with the metal foil. Another capacitor fabrication process includes separation layer forming a separation layer on one surface of a substrate, dielectric layer forming a dielectric layer on the separation layer, metal foil forming a metal foil the dielectric layer, separating the substrate from the separation layer, and an electrode layer forming an electrode layer on the second surface of the dielectric layer, wherein the second surface faces away from the first surface of said dielectric layer with the metal foil. A thin-film capacitor has higher capacity, is so slimmed down and has a form well fit for being buried in a base board, and can be used even at high frequencies. |
