Abstract: A measuring apparatus including: a transmission part transmitting a probe packet wherein a communication apparatus to be measured is arranged in a communication path destined for a destination-communication apparatus, a reception part receiving a response packet from destination-communication apparatus in response to the probe packet, a time-measuring part measuring time, an analyzing part analyzing the response packet, an output part outputting an analysis result, the analyzing part calculating analysis result based on measuring result of the time-measuring part.

Abstract: An information processing device acquires a first position indicating a physical position of a first communication device, a second position indicating a physical position of a second communication device, and a plurality of third positions indicating physical positions set in a path connecting the first position and the second position; and searches for a physical path corresponding to a communication path of the first communication device and the second communication device based on the first position, the second position, and the plurality of third positions.

Abstract: In order to finely crush a shredable object, two rotational shafts for supporting cutting blades are provided in parallel in the transverse direction inside a shredder main body. The cutting blades that are provided with a plurality of cutting portions protruding from outer peripheral thereof are disposed in the shaft direction of the two rotational shafts so that these cutting portions engage with each other. A throw-in port for a shredable object is provided in one end portion of the rotational shafts in an upper portion of the shredder main body in the shaft direction. A discharge port for the shredable object is provided in the other end portion of the rotational shafts in a lower portion of this shredder main body in the shaft direction.
