  • Publication number: 20240111735
    Abstract: A data dictionary generation system automatically populates and updates a data dictionary for listings offering shared data. A data dictionary includes metadata describing the shared data, including the individual objects, such as the individual tables, schemas, views, and functions. The shared data and each individual data object may be described in the data dictionary by a set of data fields that corresponds to the shared dataset or the object type of the individual object. The data dictionary can be presented to data consumers along with the description of the listing to provide data consumers with a comprehensive description of the shared data provided by a listing, including a high-level summary of the shared data and description of each individual object included in the shared data. The data dictionary allows data consumers to understand the contents of the shared data and how to use the shared data.

  • Publication number: 20230182199
    Abstract: A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.

  • Publication number: 20220258277
    Abstract: The invention relates to apparatuses and correspondent method of laser beam processing for various materials with strong light absorption and scattering. The apparatuses can be used for medical no incision laser surgery, long distance underwater or atmosphere light communication, less attenuation light energy delivery in optical turbid media, and so on. This invention is a new use of the imaging method using multiple beam interference to create destructive interference in the beam propagation path to reduce the illumination light intensity and so to reduce absorption and scattering of the materials, and to create constructive interference to produce high composite light intensity which forms an inner light layer to illuminate, process the inner object in the materials. The apparatuses are practicable and have great performance.
