A spectrum analyzer then observes the spectrum of the first optical signal and the spectrum of the second optical signal, and provides an observational result.

The second WSS takes the remaining wavelength from the second path and combines it with an optical signal from a third path to create a second wavelength-multiplexed optical signal. Another spectrum analyzer then observes the spectrum of the third optical signal and the spectrum of the fourth optical signal, and provides a second observational result.

In summary, the system separates and combines wavelength-multiplexed optical signals using WSSs, and analyzes the spectra of the signals using spectrum analyzers to obtain observational results.

Abstract

A first WSS performs demultiplexes a first wavelength-multiplexed optical signal, outputs part of the wavelengths to a first path, and outputs a remaining wavelength to a second path. A first spectrum analyzer observes a spectrum of a first optical signal included in the first wavelength-multiplexed optical signal and a spectrum of a second optical signal output from the first WSS and outputs a first observational result. A second WSS outputs a second wavelength-multiplexed optical signal obtained by multiplexing an optical signal input from a third path to an optical signal of the remaining wavelength input from the second path. A second spectrum analyzer observes a spectrum of a third optical signal included in the optical signal input to the second WSS from the second path and a spectrum of a fourth optical signal output from the second WSS, and outputs a second observational result.

MANAGEMENT DEVICE, MANAGEMENT METHOD, AND RECORDING MEDIUM (18020132)

Inventor Ryo SHIBASAKI

Brief explanation

The abstract describes a system that temporarily stores messages sent by a sender to multiple destinations. The system detects if there is a cancellation request sent from one of the destinations back to the sender. If a cancellation request is detected, the system determines that the original message sent by the sender should be deleted.

Abstract

The message information items including, as attributes, a sender and multiple destinations, and having been sent in advance to one or more destinations among the multiple destinations after having been received from the sender, are temporarily stored. A correspondence is detected between a message information item sent from the sender to the one or more destinations and a message information item sent to the sender as a cancellation request from one destination among the one or more destinations. In the case in which a correspondence is detected between a message information item sent from the sender to the one or more destinations and the message information item sent to the sender as the cancellation request from the one destination among the one or more destinations, it is determined that the message information item sent from the sender to the one or more destinations is to be deleted.

INFORMATION PROVIDING APPARATUS, INFORMATION PROVIDING SYSTEM, INFORMATION PROVIDING METHOD, AND NON-TRANSITORY COMPUTER-READABLE MEDIUM (18022923)

Inventor Yuki Hashimoto

Brief explanation

The abstract describes a system that registers user terminals and their position information as a group. It detects when a user reaches a location where content information is available and calculates the distance between the user and other terminals in the group. Based on this distance, it controls the provision of content information to the user's terminal and other terminals in the group.

Abstract

A registration unit registers pieces of identification information of user terminals possessed by users, respectively, as a group. A position information acquisition unit acquires pieces of position information of the plurality of user terminals registered as the group. A reaching detection unit detects, from position information of a first user terminal possessed by one user, that the one user among the plurality of users registered as the group has reached a position where content information is provided. When the reaching is detected, a distance calculation unit calculates a distance between the first user terminal and another user terminal. In a case where the reaching is detected, a provision control unit provides the content information to the first user terminal, and controls provision of the content information to another user terminal possessed by another user of the group based on the calculated distance.
