Abstract: Provided is a management system for solving the problem of an increase in the load on a network when managing the location of a mobile object in the cloud. The management system includes: a mobile object for estimating the location of a host device after a predetermined time has elapsed, using a predetermined motion model; and a management device for estimating the location of the mobile object after the predetermined time has elapsed, using the predetermined motion model. The mobile object transmits information relating to the location of the host device to the management device in response to the fact that the error between the location of the host device measured after the predetermined time has elapsed and the estimated location of the host device has exceeded a predetermined threshold value.

Abstract: A base station (1) is connectable to a mobile station (4) by a plurality of Radio Access Technologies (RATs) including first and second RATs. The base station (1) is configured to be able to use a communication path (400) that passes through a first upstream network (140) corresponding to the first RAT, when the mobile station (4) performs communication via the second RAT. This enables, for example, efficient use of the upstream networks when the Multi-RAT base station (1) supports a plurality of upstream networks.

Abstract: A movement vector calculation unit calculates movement vectors between frames of a video image of an area ahead of a vehicle. The video image is input as a moving image. An area inference unit infers an area indicating a movable object included in the video image of the area ahead of the vehicle. A vector excluding unit excludes, from among the calculated movement vectors, movement vectors in an area inferred as being the area indicating the movable object. A behavior inference unit infers behavior of the vehicle based on the movement vectors from which those in the area inferred as being the area indicating the movable object have been excluded.

Abstract: A control apparatus controls communication in a vehicle by setting a control entry(ies) to a plurality of switches relaying, by referring to the control entry(ies), a packet(s) input to and output from an ECU(s) installed in the vehicle. The control apparatus sets a second control entry for detecting the packet(s) transmitted from the ECU(s), triggered by that a frequency of communication of the ECU(s) exceeds a predetermined threshold value, and determines any one of failure of the ECU(s) and a fault of a communication path(s) according to combination of the switch(es) and a port(s) in which interruption of the packet(s) transmitted from the ECU(s) is detected.

Abstract: The present invention is directed to perform high-reliable authentication using a one-way function that a communication is a communication which was performed with the same apparatus to be authenticated by storing a password only in an apparatus to be authenticated (it is unnecessary to store a password in both of an authentication apparatus and an apparatus to be authenticated) without transmitting a challenge code. When a setting is updated in a setting management server, authentication is performed by using a one-time password obtained last time. A sound communication terminal performs a process using a hash function once on a one-time password transmitted this time, and performs authentication by determining whether the processed one-time password matches a one-time password obtained last time or not. Whether the information at the time of the change in the setting is proper or not is determined by a sound terminal.
