  • Patent number: 10453634
    Abstract: A wireless switch includes a cover member, a button member, a first plunger, a second plunger, a trigger spring, a return spring, a shaft, a housing, and a power generation module. An intermediate member constituted of the first plunger, the second plunger, the trigger spring, the return spring, and the shaft is connected between the button member and the power generation module. The intermediate member prevents a position of the shaft making contact with the power generating shaft of the power generation module from changing, and causes stress to build up in the trigger spring, until a movement distance of the button member reaches a predetermined distance. The intermediate member releases the stress built up in the trigger spring and pushes the power generation shaft with the shaft using the released stress upon the movement distance of the button member reaching the predetermined distance.

  • Patent number: 10225750
    Abstract: A module transmits send information to be processed by an information processing apparatus along a transmission path on which the information processing apparatus is present. When the send information is sent in accordance with predetermined sending parameters, if a sending failure in which a sending completion state of the send information cannot be confirmed occurs, a part or all of the sending parameters used for sending of the send information with respect to which the sending failure has occurred are changed, and the send information is resent in accordance with the sending parameters after the changing. Then, the predetermined sending parameter changed between the occurrence of the sending failure and confirmation of the sending completion state of the resent send information, and resend result information related to a send result corresponding to the changed predetermined sending parameter are acquired and sent toward a predetermined processing apparatus.
