  • Publication number: 20230341556
    Abstract: The present technology relates to a distance measurement sensor, a signal processing method, and a distance measurement module that enables detecting that an object to be measured is a transparent object such as glass. The distance measurement sensor includes a signal processing unit that calculates a distance to an object and a degree of confidence from a signal obtained by a light receiving unit that receives reflected light returned by reflection, by the object, of irradiation light emitted from a predetermined light emitting source, and outputs a determination flag determining whether or not the object that is an object to be measured is a transparent object. The present technology can be applied to, for example, a distance measurement module that measures a distance to a subject, and the like.

  • Patent number: 5596706
    Abstract: A highly reliable online system is disclosed which is provided with a backup computer center (sub-online system) in addition with an original computer center (main online system) in order to improve the reliability of the online system. With respect to the database, the main online system is provided with an original database (main database) while the sub-online system is provided with a backup database (sub-database) which is a duplicate of the main database. The main online system and the sub-online system are connected through a transmission path. Information on an update performed in the main database is transferred to the sub-online system through the transmission path to thereby update the sub-database in a manner similar to the main database. Terminal units are normally connected to the main online system, wherein the main database is updated by transactions inputted from the terminals.
