Abstract: The present invention makes it possible to identify software that is safe and determines what software can be rolled back while maintaining a high level of safety and security. A software updating device E1000 includes: software unit storage E1520 that stores a plurality of software units UX000 that include label information UX400; and an update control unit E1400 that controls software updates for a vehicular control device ECU_EX000. The label information UX400 includes at least safety-related information for the software units UX000. Upon receiving a rollback command, the update control unit E1400 selects software from the plurality of software units UX000 that has safety-related label information UX400 that is identical to safety-related label information UX400 of software installed at the vehicular control device as software to roll back.

Abstract: Function definition information is prepared in a system. The function definition information is information representing a correspondence relationship among a software-based function, a vehicle ID of a vehicle, a hardware configuration for implementing a function, and a software configuration for implementing a function. The system performs a preliminary determination including a determination of a relationship between one or a plurality of user-desired functions constituting a user-desired function group of a user and a hardware configuration of a target vehicle based on the function definition information. For each of the one or more functions specified in the preliminary determination, in order to implement the function in the target vehicle, the system develops a software configuration corresponding to the function in a hardware configuration corresponding to the function in the target vehicle.

Abstract: Provided are a route information storage DB in which route information indicating a travel route for a vehicle is saved, a maintenance information storage DB in which maintenance information regarding maintenance of the vehicle is saved, an environment information storage DB in which environment information regarding the route is saved, a program storage DB in which a program to be used in the vehicle is saved, a computation unit that executes, based on the route information, the maintenance information, and the environment information, computing of evaluation indexes regarding optimization of travel control of the vehicle for respective cases each obtained by making a change in a program-parameter combination for the vehicle, and that determines a program-parameter combination which provides an optimal result among the computed results, and a communication unit that transmits, to the vehicle, the program-parameter combination determined by the computation unit.

Abstract: A composition for making a fired dental porcelain is disclosed which composition comprises a powder dental porcelain frit material and a second material. The second material is selectively etchable from a fired dental porcelain prepared from the composition and the second material can, upon such firing of the composition, maintain a separate phase so that, when the composition is formed into a fired dental porcelain having a dental porcelain surface to be bonded to a dental substrate and the dental porcelain surface is etched to remove second material therefrom, the porosity and surface area of the dental porcelain surface will be increased to provide enhanced bonding of the dental porcelain surface to the dental substrate. Also disclosed are fired dental porcelains prepared therefrom and methods of making and using same.
