  • Publication number: 20230264342
    Abstract: A control system includes a master device, a slave device, and a control device that controls the master device and the slave device. In the control device, a response value acquisition unit acquires data of physical quantities representing action of the movable portion of the master device, and data of physical quantities representing action of the movable portion of the slave device. A command value calculation unit hypothesizes a virtual object that includes the master device and the slave device, and calculates a command value for causing the master device and the slave device to follow behavior expressed in the virtual object by input to the master device and the slave device, on the basis of the data of physical quantities acquired by the response value acquisition unit.

  • Publication number: 20230269095
    Abstract: An information processing apparatus acquires a first verifiable credential (VC) that proves the validity of attribute information of a holder by a first signature verifiable by verification procedures of a first decentralized identifiers (DID) infrastructure and a second VC that proves the validity of the attribute information of the holder by a second signature verifiable by verification procedures of a second DID infrastructure. Next, the information processing apparatus verifies the second signature contained in the second VC by the verification procedures of the second DID infrastructure. Further, the information processing apparatus transmits a verification request for verifying the first signature contained in the first VC to a verification device capable of verifying the first signature contained in the first VC by the verification procedures of the first DID infrastructure, and then acquires, from the verification device, verification results of the first signature contained in the first VC.

  • Patent number: 11712451
    Abstract: An object of the present invention is to provide, for example, a more practical wound healing accelerator that more effectively accelerates wound healing. More specifically, a feature of the present invention is to provide, for example, a more practical wound healing accelerator that is easily obtained in a larger amount than that of peripheral blood platelet and has a better wound healing effect than that of peripheral blood platelet. The present invention employs a platelet-like cell population coexpressing one or more platelet surface markers and one or more mesenchymal cell surface markers. A wound healing accelerator containing the platelet-like cell population is a more practical wound healing accelerator that more effectively accelerates wound healing. The platelet-like cell population is easily obtained in a larger amount than that of peripheral blood platelet and has a better wound healing effect than that of peripheral blood platelet.
