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 configured to calculate a feature related to driving of a vehicle includes a first processor configured to receive input information including information on a speed of the vehicle and a second processor configured to calculate the feature by using the input information received during a first period in which predetermined conditions are satisfied. The first period being included in a second period in which the input information is received. The predetermined conditions include a condition that a driving operation is performed before a brief stop of the vehicle.

Abstract: In a case connection structure for connecting connection end portions of both case members, a boss portion is formed in one of the connection end portions to protrude to the other one of the connection end portions, and a recess portion into which the boss portion is fitted is formed in the other one of the connection end portions. A slit is provided in the boss portion, and a press-fitting portion is provided in the recess portion to be press-fitted into the slit. While the boss portion is fitted into the recess portion, the press-fitting portion is press-fitted into the slit to expand the boss portion to an outer side, so that an outer surface of the boss portion press-contacts the recess portion.

Abstract: In an electric blower, exhaust air discharged radially from a centrifugal fan is redirected to a motor drive section by a diffuser and a fan cover. The air passes from a ventilation opening on a motor frame and through a bracket to cool the motor drive section. A portion of the air from the centrifugal fan is bled off through exhaust openings without passing over the motor, whereby this portion remains cooler and cleaner than the air that passes over the motor. Air flows up a wand and then passes over the motor to cool the motor. This air passes through filters before being discharged. The portion of air that is bled off passes along a parallel path in the wand to agitate dirt, and to maintain the wand relatively cool. In one embodiment, some of the bled-off portion is discharged directly without passing along the wand.
