Abstract: The information processing device determines whether or not to re-lease the first vehicle after returning from the lease. The information processing device includes a control unit. The control unit is configured to acquire, for the first vehicle, a evaluation result of a state according to a predetermined evaluation method, and output that the first vehicle is to be leased again when the evaluation result indicates that the first vehicle does not require repair, and output that the first vehicle is to be sold when the evaluation result indicates that the first vehicle needs repair.

Abstract: A protector that lightens a shock when a wearer falls, and reduces an unpleasant feeling given to a wearer when worn for a long period of time. The protector is substantially circular in a plan view and is disposed at a position to cover near a femoral-neck portion from a side portion of a wearer. The protector is curved in a thickness direction so that an outer surface, comprising a single-layer structure composed of a polymer-foam body, is convex, and an inner surface is concave. An amount of displacement in the thickness direction when a load of 20 N is applied at a central portion of the outer surface when placed on a flat surface is 3 mm-20 mm.

Abstract: To enable to control an audio sound to a suitable volume level corresponding to the using condition of electronic equipment. In a portable disk device 2 that can be attached to a cradle 3, a connection detecting line DET connected to a control part 50 for detecting an attached state or an unattached state to the cradle and a pullup resistance 56, the control part 50 for controlling to set, if it is detected that the portable disk device 2 is in the unattached state, an audio sound to be emitted from the above portable disk device 2 to dedicated headphones 15 to a volume level based on a predetermined headphone volume value VH, and to switch, if being in the attached state is detected, an audio sound to be emitted from speakers 4L and 4R via the above cradle 3 from the volume level based on the headphone volume value VH to a volume level based on a line volume value VL larger than the above headphone volume value VH, and a DSP 53 are provided.
