An object of the invention is to provide a new defect detection technique using an autonomously movable apparatus. In order to accomplish the object, the invention provides a detection system () including a drive control unit () that controls a driving unit () causing a base unit () to travel in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit () installed in the base unit (), and a second detection unit () that detects a predetermined defect on the basis of the information collected by the sensor unit ().

Detection system, detection method, and program

The present invention is provided to implement an automated setting change of network setting items on an ad hoc network which does not have a specific base station. A method of changing network setting for changing setting of a network where a plurality of terminals are connected, the method including the steps of: a request source terminal transmitting a request for setting change to a selected representative terminal; the selected representative terminal, upon receiving the request for setting change, transmitting a request for permission to at least a majority of representative terminals; the selected representative terminal transmitting a success notification to the request source terminal upon receiving a notification of permission from the majority of representative terminals in response to the request for permission; the request source terminal transmitting, to the plurality of terminals, an execution instruction including at least a content of setting change, upon receiving the success notification; and the terminal which has received the execution instruction changing the setting according to the content of setting change.

Network setting change method and system thereof, and terminals which are used with said system

A mobile ad hoc network including the communication terminals for cognitive radio communication may have a problem that it takes time for the terminal to newly participate in the network. A radio communication terminal already participating in a mobile ad hoc network includes a pulse pilot generating unit which converts a pulse signal having a predetermined pattern into a radio signal and outputs the obtained radio signal at an unused frequency, after participating in the mobile ad hoc network. A radio communication terminal to participate in a mobile ad hoc network includes a pulse pilot checking unit which checks whether any pulse signal having a predetermined pattern exists in a radio signal for each predetermined frequency and performs a participation process for the frequency of each radio signal including the pulse signal, the participation process including inquiring whether the radio communication terminal can participate in the mobile ad hoc network.

Radio communication terminal, mobile ad hoc network, and network participation method

A sensing device includes a situation acquisition unit acquiring information on situation of a site of interest sensed; a sensing range change unit changing sensing range of the situation acquisition unit; a position identification unit identifying position of the situation acquisition unit; and a sensing operation controlling unit which detects inhibited content, a subject of inhibition of transmission, from the information on the situation of the site of interest. If the inhibited content has been detected, the sensing operation controlling unit calculates position of the inhibited content based on the position identification information from the position identification unit. The sensing operation controlling unit controls the sensing range change unit, based on the position identification information including the position of inhibited content calculated, so that the position of inhibited content is not contained in the sensing range. An inhibited content detection unit outputs information on the site of interest to an operation terminal upon non-detection of inhibited content.

A remote operation robot system for having a robot perform a task by remote operation includes an operating device connected to a communication network, an operating terminal connected to the network, and a server. The operated device performs the task in accordance with a remote operation via the communication network. The operating terminal operates the operated device via the communication network. The server holds operated side information about a request, from a device user of the operated device, to have the task performed. The server holds operating side information about a request, from a terminal operator of the operating terminal, to perform the task. The server determines a combination of the operated device and the operating terminal that operates the operated device based on the operated side information and the operating side information, and notifies the operated device and the operating terminal of the combination.

A facial image identifying apparatus checks a facial image of a user captured by an image capturing unit such as a camera or the like against facial images of registered users for thereby identifying the user. When the facial image identifying apparatus starts to detect a facial image of an examinee user, it determines whether a situation of the image captured by the image capturing unit is appropriate to detect the facial image. If the situation is judged as being inappropriate, then information representing that the situation is inappropriate is presented to the examinee user. Based on the presented information, the examinee user can make an action to improve the situation of the captured image.

Identification of facial image with high accuracy

A robot is provided, wherein it is possible to reduce incorrect identification in the case of executing face identification in a place where lighting variations are large such as in a house and in a place where there exists a lighting environment that is bad for identification. A face area of a person is detected from an image picked up at an imaging means and stored, and a face detecting and identifying means identifies a person using face image information stored before then. An identification result reliability calculating means calculates, using information from the imaging means, whether or not a present lighting state is suitable for face identification. When the result of calculation indicates that the lighting state is not suitable for face identification, the robot is moved by a moving means. Thereby, incorrect identification can be reduced.
