There is provided an information processing system including a relative-position estimation processing unit configured to estimate a relative position between an access point and a wireless client by using a cooperative position estimation method using distance information based on a signal strength between the access point and the wireless client; and an inside/outside determination processing unit configured to determine an inside/outside positional relationship between a polygonal target area formed by access points and the wireless client, in which the inside/outside determination processing unit determines whether the wireless client is present inside or outside the target area by determining a direction of vector product of the access points forming a side of the target area and a direction of vector product of the wireless client and the access point as a vertex of the polygonal area.

Information processing system

A purpose is to provide a monitoring system to monitor whether there is a substance to be monitored in the air, and a detecting device used in the monitoring system. The monitoring system includes a detecting device, an analyzing device, and an abnormality notification system. The detecting device determines whether the air is in an abnormal state on the basis of an output signal from an abnormality detection sensor, pours liquid to be inspected, into which the air is sucked and liquefied, into a previously-installed reagent container when determining the abnormal state, generates mixed liquid in which a reactant in the reagent container and the poured liquid to be inspected are mixed, and drops the generated mixed liquid to an electrode of the analyzing device. The analyzing device determines existence/non-existence of a substance to be monitored on the basis of the mixed liquid dropped to the electrode, and gives a predetermined notification to the abnormality notification system when determining that there is the substance to be monitored. The abnormality notification system gives a predetermined notification when receiving the notification from the analyzing device.

Monitoring system and detecting device

An attachment mechanism for attaching to a wall a network device for assisting a communication device in communicating on a network includes a heat radiation member, engaged with and supporting a housing of the network device, for radiating heat from the network device, and an attachment member, engaged with the heat radiation member, for attaching to the wall the heat radiation member engaged with the housing.
