Abstract: A machine and its associated process for upset forging the ends of deformed reinforcement bars are disclosed. The machine includes 2 split clamping dies and an upsetting die, and they are housed in separate casings so that the clamping action is independent from the upsetting die. The clamping dies and the upsetting die form a continuous cavity for accommodating the forging of long bars. The upsetting die has a upsetting cavity with radial closed cross-section, and the whole forging process is performed inside this closed cavity to ensure it's a true closed-die forging process, which results in precise upset diameter with improved roundness of the rebar.

Abstract: Techniques for storing health data can include a multi-node data structure. A data node, a category node, and an institution node of a multi-node data structure can be generated in accordance with a configuration file. The data node can include health data and can be identified by a first unique data identifier and encrypted using a first cryptographic key. The category node can include the first unique data identifier and the first cryptographic key. The category node can be identified by a second unique data identifier and encrypted using a second cryptographic key. The institution node can include the second unique data identifier and the second cryptographic key. The institution node can be identified by a third unique data identifier and encrypted using a third cryptographic key. The data node, the category node, and the institution node can be shared with a service provider.

Abstract: A user device may share encrypted health data with an electronic health record (EHR) system associated with a health institution. A unique data identifier that identifies a portion of the health data and a cryptographic key may be shared with the EHR system. The encrypted health may be shared with a service provider and a unique data identifier. To access the health data, the EHR system may query the service provider with the unique data identifier.

Abstract: A clamping structure and a tactical light, wherein a sliding groove is provided on a bottom part of a clamping space; a plurality of first positioning areas are provided inside the sliding groove along its length direction; a sliding block is slidably provided inside the sliding groove; a plurality of first positioning portions are provided on a side of the sliding block facing the first positioning areas; an abutting component is fixed on the sliding block; when the sliding block slides inside the sliding groove, the abutting component slides along with the sliding block inside the clamping space to adjust the position of the sliding block relative to the clamping device, also, each first positioning portion moves from one first positioning area to another one, thereby fixing the sidling block inside the sliding groove, and realizing adjustment of the position of the clamping device relative to the sliding block.
