  • Publication number: 20220148198
    Abstract: A plurality of motion vectors are acquired from consecutive images. From the acquired plurality of motion vectors, a motion vector of interest and neighboring motion vectors neighboring the motion vector of interest are selected and a degree of similarity between two motion vectors is acquired. A value related to the total number of neighboring motion vectors having high degrees of similarity to the motion vector of interest is acquired as a degree of reliability.

  • Patent number: 11281430
    Abstract: In an information processing device, a fluctuation estimation unit acquires from a noise source a plurality of measured values having bits of M digits, where M is an integer exponent of a power of two. A bit extraction unit acquires information relating to a number of effective bits of N digits used in generating a random number, where N is an integer less than M, based on the acquired plurality of values. Using the information relating to the number of effective bits, a bit coupling unit generates a random number having effective bits of L digits, where L is a predetermined integer greater than or equal to N.

  • Patent number: 11190354
    Abstract: A terminal exchanges a common key generated using a seed, the randomness of which was recognized in advance, with a verification server. The terminal generates verification data using a plurality of measured values from a noise source. The terminal encrypts the verification data with the common key and transmits the verification data to the verification server. The verification server verifies the randomness of verification data obtained by decrypting the encrypted verification data with the common key. When it is determined that the verification data has randomness, the verification server transmits a verification result indicating that the randomness of the verification data is recognized to the terminal. The terminal acquires a plurality of measured values and generates a new seed in accordance with the verification result from the server and preserves the new seed in a secure area.

  • Publication number: 20210156457
    Abstract: An actuator has: a motor section; a ball spline having a finite stroke and equipped with a shaft capable of moving along its axis; an external screw thread formed on the shaft; a nut section having an internal screw thread engaging the external screw thread and operating to transmit the rotary force of the motor section to the shaft; and a case housing the motor section and the ball spline. The shaft has a contact section at its front end, the contact section being designed to make contact with the driven object. The contact section is lower than the shaft in thermal conductivity. Due to heat generated by the motor section, the shaft elongates along the axis of the shaft in a first direction, and the case elongates along the axis of the shaft in a second direction opposite to the first direction.
