Abstract: A strength meter in a relay attack determination device is disposed on a portable device and measures a reception strength by a plurality of times in each of a request signal and a request signal received from an in-vehicle device. A comparator executes a comparative process of the request signal and the request signal by using average values of the reception strength measured by the strength meter. A variation calculator calculates variation in the reception strength measured by a plurality of times in the strength meter regarding the request signal. The comparator, in a case where the variation in the reception strength exceeds a threshold value indicating a communication failure in the request signal, determines the relay attack regardless of a result of the comparative process.

Abstract: A portable device includes a reception antenna and a strength meter. The reception antenna includes antennas of three axes each receiving a first signal and a second signal. The strength meter measures a reception strength of the request signal and the request signal received by each of the three axes of the LF receiver. A relay attack determination device is provided with a comparator that executes a comparative process of strength ratios of the request signal and the request signal based upon a measurement value of the reception strength. In a case where the three axes include an ineffective axis, in which the measurement value of the reception strength of the request signal or the request signal deviates from a usable range, the comparator excludes the ineffective axis and executes the comparative process.

Abstract: An culture vessel includes one or more recesses, each having a flat bottom surface, and a side surface extending upward from the peripheral edge of the bottom surface and including a rough surface with arithmetic mean roughness of 0.18 ?m to 5.0 ?m. The rough surface is water repellent and reduces meniscus formation on the peripheral edge of the upper surface of the culture solution. This suppresses a reduction in light amount at the peripheral edges of recesses due to meniscus formation. On the side surfaces of recesses, secondary illumination light is diffused and reflected. This suppresses formation of an image (ghost) of a biological sample by the secondary illumination light. Accordingly, it is possible to suppress a reduction in the amount of light due to meniscus formation in the culture solution and to reduce formation of an image of the biological sample by the secondary illumination light.
