    Abstract: A wireless communication apparatus includes a wireless communicator and a controller. The wireless communicator is configured to wirelessly communicate with other wireless communication apparatuses. The controller is configured to control the wireless communicator to broadcast transmission information, and when the wireless communicator receives a request corresponding on the transmission information from at least one of the other wireless communication apparatuses having received the transmission information during the broadcasting of the transmission information, control the wireless communicator to change transmission power of the transmission information to the other wireless communication apparatuses.

    Abstract: A communication apparatus includes a communication unit and a controller. The controller determines, according to a first reference of received signal strength in one communication apparatus which is either an external communication apparatus or the communication apparatus, a transmitted signal strength for a transmission radio wave from the other communication apparatus as a first reference of transmitted signal strength. The controller determines a second reference of transmitted signal strength between the first reference of transmitted signal strength and a maximum strength of transmitted signal strength from the other communication apparatus. When a predetermined condition is satisfied, the controller obtains a received signal strength of the one communication apparatus for the transmission radio wave in the second reference of transmitted signal strength and determines a transmitted signal strength of a transmission radio wave from the other communication apparatus according to the received signal strength.

    Abstract: A biometric authentication device has a structure member which is wearable to a user, and a biological information acquisition unit that acquires biological information of the user, and a biometric authentication unit that performs authentication of the user. The biological information acquisition unit is provided in a position where a finger of the user in contact when the structure member is worn/removed to/from the user, acquires first biological information with the finger of the user in contact with the biological information acquisition unit and second biological information which is at least one of a finger direction and action data, the finger direction is a direction of the finger in contact with the biological information acquisition unit and the action data is a data corresponding to spatial movement of the biometric authentication device when the structure member is worn/removed to/from the user. The biometric authentication unit performs the authentication based on the first and second biological information.
