  • Publication number: 20210110398
    Abstract: A fraud detection system that converts personal identification information into an irreversible code, acquires transaction information that includes transaction terminal identification information, stores the acquired transaction information in a transaction information storage unit, and calculates a respective transaction estimation value for a future transaction for each transaction terminal and each irreversible code, on the basis of the transaction information stored in the transaction information storage unit. When new transaction information is acquired the fraud detection system calculates a degree of deviation for the new transaction information on the basis of the transaction estimation value for the irreversible code and the transaction estimation value for the transaction terminal which are in accordance with the transaction terminal identification information included in the new transaction information, and outputs alert information when the degree of deviation is large.

  • Patent number: 10901299
    Abstract: An electronic apparatus equipped with a camera includes a shutter mechanism which includes: a plate that is installed so as to be able to move between a first position shielding a lens of a camera from light and a second position not shielding the lens of the camera from light; and a control unit that controls electric power from a power unit that causes a first wire or a second wire to thermally shrink. The plate is moved from the first position to the second position by the first operation lever, and, when the plate is in the second position, causes the second wire to thermally shrink to thereby drive a second operation lever, so that the plate is moved from the second position to the first position by a biasing force of a first spring.

  • Patent number: 10802589
    Abstract: A method of driving an actuator using a shape memory alloy is provided. An impact-driven actuator is activated by a pulse voltage generated by an action of a transistor. A keyboard outputs a key event at the timing of an input operation. A stress monitoring unit calculates a stress amount of an impact-driven actuator based on parameters of a key event and a pulse voltage. A stress adjustment unit changes the parameter of the pulse voltage when the stress amount reaches a permissible value. The parameter may be a wave crest value or a pulse width of the pulse voltage. The stress adjustment section is also able to stop the action of the impact-driven actuator in response to a key event corresponding to a break code.
