Abstract: An acquiring unit acquires the positional information. A first request unit requests an authentication station to perform authentication by using the positional information acquired by the acquiring unit. When the authentication station grants authentication for a request from the first request unit, a communication processing unit carries out communications using a first radio communication system. When authentication required for carrying out the communications using the first radio communication system is not performed in the communication processing unit, a second request unit requests another terminal apparatus to perform authentication by using a second radio communication system, whose transmission distance is shorter than the first radio communication system.

Abstract: A motion analysis device has a determination unit which uses an output from an inertial sensor mounted on at least one of a subject and a tool operated by the subject, to determine a dominant hand of the subject in a swing. The determination unit can determine the dominant hand on the basis of the sign of angular velocity or acceleration from the inertial sensor. A calculation unit which calculates motion analysis information in a swing, using an output from the inertial sensor can add dominant hand information from the determination unit to the motion analysis information. The motion analysis device can include a coincidence determination unit which determines that a first subject and a second subject have different dominant hands, and an inverted image generation unit which inverts first motion analysis information in the case of no coincidence.

The display unit displays the posture of the interest part of the sporting equipment at the checkpoint.

Abstract: In a motion analysis device, a first detection section detects a first state of a shaft portion of sporting equipment using an output of an inertial sensor. The first state corresponds to, for example, a resting state. A second detection section detects a second state of the shaft portion of the sporting equipment using the output of the inertial sensor. The second state corresponds to, for example, an impact. The second detection section detects a relative rotational angle of the shaft portion having varied around an axis of the shaft portion from the first state.

The course of the hit ball is estimated with the posture of the hitting area at impact. The type of the course of the hit ball is determined in accordance with the posture of the hitting area.

Abstract: When a plurality of sub-station monitoring apparatuses are controlled by a main station monitoring apparatus, if the sub-station monitoring apparatus detects a change of a plurality of events, the sub-station monitoring apparatus transmits information relating to the event such as the kind of change, the time of event occurrence, or the like to the main station monitoring apparatus instead of transmitting image data. The main station monitoring apparatus determines abnormality/normality of the occurred event, and requests the corresponding sub-station monitoring apparatus to transmit still image data or moving picture data when there is a possibility of abnormality, so as to monitor the event in detail.

Abstract: An apparatus that controls opening and closing of a roof glass is disclosed. The apparatus includes a drive motor that is actuated to selectively open and close the roof glass. The apparatus stores a count value that changes in correspondence with operation of the drive motor. The apparatus detects the number of cycles of reset starting and determines whether the detected number of the reset starting cycles is in a predetermined acceptable range. The apparatus switches initial setting, in accordance with which the relative relationship between the actual open/closed position of the roof glass and the count value is determined, to a non-set state if it is determined that the number of the reset starting cycles exceeds the acceptable range.
