The registration device generates aggregate information indicating one or more aggregate values, by aggregating a plurality of attribute values included in the attribute information. The registration device generates generalized information indicating a plurality of generalized values for each aggregate value by generalizing each aggregate value included in the aggregate information. The registration device generates ciphertext data including the plaintext encrypted, by using the plaintext, the attribute information, the generalized information, and the registration key. The registration device registers the ciphertext data in a database.

Abstract: The control system includes a first controller and a second controller. The second controller includes a processor that processes the first command value by a program to output an operation command value for the motor, and a logic circuit having a circuit structure that monitors a state index indicating a state of the power controller and converts the operation command value output into the drive signal. The first controller is configured to, in a case where a failure of the processor is detected when the electrified vehicle is started up, determine whether a limp home mode is executable, based on the state index, and, in a case where a determination is made that the limp home mode is executable, output a second command value based on the limp home mode to the logic circuit instead of the first command value.

Abstract: In performing wireless communication between terminals to perform time difference measurement and propagation time measurement, first and second terminals that transmit a signal at least once in attempting space-time synchronization are included. The first terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the second terminal, adds a positive or negative phase to the measured reception phase, and makes a report to the second terminal. The second terminal measures a reception phase of a locally transmitted signal, and a reception phase of a signal transmitted by the first terminal, and makes a report to the first terminal. The first and second terminals obtain a time difference or propagation time according to a reception phase measured by a local device and reported from a counterpart, and obtain additional information based on a phase reflected in the time difference or propagation time.

Abstract: To obtain deuterium in a gas state from a mixed gas of hydrogen and deuterium at a low cost. A first electrode 11 is an electrode made of a metal allowing hydrogen (H component and D component) to permeate therethrough (hydrogen permeable metal), and the hydrogen permeable metal is Pd, for example. H ions and D ions having permeated through the first electrode 11 flow to the side of a second electrode 12 in a proton conduction layer 20. When the first electrode 11 is used as an anode and the second electrode 12 as a cathode, H ions and D ions flow in the proton conduction layer 20 from the left to the right in the drawing. In that case, hydrogen component in an input gas is more likely to flow into an atmosphere on the cathode side than deuterium component, and an H/D composition ratio accordingly becomes higher in a product gas than in the input gas. In an exhaust gas extracted after H and D components in the input gas are thus consumed, D component has been enriched.
