Abstract: PROBLEM: In management system of electric vehicle charging stands, to provide added-value services such as addressing emergency charging needs of the drivers, without overly increasing the complexity of the charging controllers. SOLUTION: Charging controllers equipped with an identification tag, mobile phones with an identification tag reader, and a management server of the charging controllers are connected via the network as the system to provided various added-value services without overly increasing the complexity of the charging controllers.

Abstract: To facilitate protected distribution of digital data files, the files are segmented, and each segment (e.g. disk sector) is encrypted separately. Some segments can be left unencrypted, speeding access since less decryption is required. Different segments can utilize different encryption techniques, increasing protection against unauthorized decryption. A table stored in association with the encrypted data provides authorized users with data identifying the encrypted segments, and the form of encryption used. Decryption is accomplished with a layered set of operating system software that operates in conjunction with said table. Specialized APIs aren't used; applications programs are provided with unencrypted data using conventional APIs. Internal interfaces, invisible to the APIS, intercept normal processing calls (e.g READs) and direct them to internal decryption software that returns decrypted data back to the APIs.

Abstract: A tool magazine for an automatic machine producing various machining operations with the aid of machine tools held by a machine spindle. The magazine for replaceable tool is adapted to hold a plurality of tools each in tool holding mechanisms being held on a tool pallet mounted on a rotary table of the automatic machine. The spindle cooperates with the magazine so as to be in alignment with a tool holding mechanism of the magazine at a tool replacement position; whereby a new tool can be withdrawn from the tool holding mechanisms by the spindle or a used tool held by the spindle can be inserted into the tool holding mechanism. In addition, the magazine is indexed, to align the several tool holding mechanisms, one at a time, with the spindle at the tool replacement position by transmitting spindle movement, preferably through a tool, to the magazine.
