Communication system
A communication path in a loop form is formed by trunk lines and a redundant communication path, which is formed by a switch and a backup line. In order to be applied to a bus-type communication network such as a CAN, the switch is normally off, and the backup line is disconnected from a path in a steady state. A disconnection detection unit is provided at each of joint connectors. When any disconnection detection unit detects disconnection, the switch is closed to enable use of the redundant path.

Systems and methods for selectively processing blockchain data
An improved blockchain implementation that reduces application transaction processing bottlenecks for applications that operate on a decentralized network. For example, if an application operating on a decentralized network becomes sufficiently popular, an existing blockchain can be split into the original blockchain and an application-specific chain (or app chain) that includes blocks that only store transactions for the sufficiently popular application. A peer that is not interested in tracking transactions for the sufficiently popular application, however, does not need to track the application-specific chain. Thus, the peer can reduce the number of computational operations that are performed by simply storing block data for blocks in the original blockchain and not for blocks in the application-specific chain. |

System and methods for automatically generating a musical composition having audibly correct form
A generative composition system reduces existing musical artefacts to constituent elements termed “Form Atoms”. These Form Atoms may each be of varying length and have musical properties and associations that link together through Markov chains. To provide myriad new composition, a set of heuristics ensures that musical textures between concatenated musical sections follow a supplied and defined briefing narrative for the new composition whilst contiguous concatenated Form Atoms are also automatically selected to see that similarities in respective and identified attributes of musical textures for those musical sections are maintained to maintain good musical form. Within the composition work, chord spacing and control are practiced to maintain musical sense in the new composition and a primitive heuristics structure maintains pitch and permits key transformation. The system provides signal analysis and music generation by allowing emotional connotations to be specified and reproduced from cross-referenced Form-Atoms. |
