Abstract: A server includes means for receiving a request for conversion from a first electronic value into a second electronic value from a user's terminal via a network, means for receiving an investment instruction to invest in the second electronic value obtained by the conversion from the user's terminal via the network, holding means for holding information regarding a type of merchandise corresponding to the second electronic value and a range of the second electronic value in association with each other, means for receiving a redemption instruction to redeem the second electronic value for the merchandise from the user's terminal via the network, the second electronic value being increased or decreased by the investment, and means for referring to the holding means and performing merchandise redemption processing on a basis of the received redemption instruction.

Abstract: An information processing device calculates a feature related to driving of a driver. The information processing device includes a processor that calculates the feature, and a transmission unit that transmits the calculated feature to an outside. The processor identifies whether there is a predetermined situation in which a risk occurs when turning right or left in a small radius, and calculates, when the predetermined situation is identified, information on a driving behavior for reducing the risk that is identified from information related to at least one of a steering wheel operation, an accelerator operation, and a brake operation of the driver, as the feature.

Abstract: An information processing device calculates a feature related to driving of a driver. The information processing device includes: a processor that calculates the feature; and a transmission unit that transmits the calculated feature to an outside. The processor identifies whether there is a predetermined situation in which a risk in relation to a preceding vehicle occurs, and calculates, as the feature, information related to a behavior of the driver for reducing the risk when the predetermined situation is identified.

Abstract: An eddy current sensor assembly includes an eddy current sensor and an output signal processing circuit that processes an output signal from the eddy current sensor. The output signal processing circuit includes a mixer circuit that accepts the output signal and a signal of the predetermined frequency as input, multiplies the two signals received as input, and outputs an output signal obtained by the multiplication, and a low-pass filter that accepts the output signal output by the mixer circuit as input, cuts a high-frequency signal included in the output signal received as input, and outputs at least a direct-current (DC) signal.

Abstract: An imaging system (100) includes an imaging unit (140) configured to capture an image of a target object while the imaging unit (140) being mounted on a movable apparatus (500); and an exposure condition determination unit (161) configured to determine any one of a fixed exposure condition and an automatic exposure (AE) condition, as an exposure condition, based on a distance detected between the movable apparatus (500) and the target object.
