  • Publication number: 20230182858
    Abstract: A human-powered vehicle control device includes an acquisition unit, a first electronic controller, an operation probability output model and a second electronic controller. The acquisition unit is configured to acquire input information related to traveling of a human-powered vehicle. The first electronic controller is configured to decide control data of a device provided at the human-powered vehicle in accordance with a predetermined control algorithm based on the input information acquired and performs automatic control on the device by the control data decided. The operation probability output model outputs a probability of a rider performing an intervening operation on automatic control of the device based on the input information. The second electronic controller is configured to change a parameter for deciding the control data in a case where a probability that is output from the operation probability output model is equal to or more than a predetermined value.

  • Patent number: 8261056
    Abstract: A data communication unit receives encrypted digital data via a network and records the digital data on a primary recording medium. The digital data, having been encrypted indifferent encryption methods according to the distributors, include attribute information indicating the encryption methods. The encryption method of the digital data is determined and the encrypted data is decrypted by an appropriate decryption unit. Identification information of a secondary recording medium or a playback apparatus is obtained according to whether the secondary recording medium is removable from the playback apparatus. A controller selects an encryption unit among a plurality of encryption units according to the obtained identification information. The selected encryption unit creates an encryption key according to the identification information and re-encrypts the digital data. A recording unit records the digital data on the secondary recording medium.
