Information relating to each link based on location information of a user can be generated with high accuracy even without measuring the location information at a high frequency. A map matching unit () associates location information of a moving user at each time with pedestrian network data () formed by a plurality of nodes and links connecting the nodes through a map matching process, and a calculation unit () calculates a passage record of a link of interest as link information based on whether or not the link of interest is connected to preceding and succeeding links in a link row acquired by aligning the links with which the location information is associated in order of times of pieces of the location information.

The present invention provides a data analysis system capable of performing analysis appropriately using a CNN model while reducing communication traffic. A data analysis systemincludes: an instrumentthat performs a conversion process of outputting compression data obtained as a result of processing observation data received via an input layer of a learned neural networkA using portions ranging from the input layer to a predetermined intermediate layer; and a devicethat performs an analysis process of inputting the compression data to a subsequent intermediate layer in a learned neural networkB, inputting data obtained by decoding the compression data, which is an output of the subsequent intermediate layer, to an output layer configured using a CNN model, and obtaining an analysis result of the observation data as an output of the output layer. The learned neural networksA andB are learned in advance so as to minimize an error between the output of the output layer when observation data of which the true analysis result obtained by analysis is known is input and the true analysis result and an error between the observation data and the decoded data.

It is intended to allow an appropriate route search to be performed even with a geographical NW in which accessibility information includes an uninvestigated link. A route appropriateness value calculation unitcalculates, for each of a plurality of routes each connecting a departure point and a destination extracted by a route extraction unitand including links connecting individual spots including the departure point and the destination, a route appropriateness value of the route. The route appropriateness value of the route is calculated on the basis of a cost of the route calculated by a cost calculation uniton the basis of a cost representing a degree of passage difficulty which is determined for each of the links with respect to a transportation means on the basis of accessibility information of the investigated link as well as a degree of passage uncertainty representing a possibility that the route cannot be passed through by the transportation mean which is calculated by a passage uncertainty degree calculation uniton the basis of a length of the uninvestigated link included in the route. A route selection unitselects, from among the plurality of routes, the route on the basis of the route appropriateness value of the route.

A collection device includes a deciding unit that, on the basis of data obtained in advance for each area, decides a collection interval and a collection time for each of the areas, a communication unit that acquires a current position from each of measurement terminals, and an allocating unit that, in a case where there is an area corresponding to the current position acquired regarding each of the measurement terminals, calculates a slot count of slots regarding which the collection interval and the collection time are cyclically allocated, on the basis of the collection interval and the collection time of this area, and allocates slot Nos. of an amount equivalent to the slot count, to any of the measurement terminals present in this area, by a predetermined method. The communication unit transmits, to each of the measurement terminals to which slot Nos. are allocated, the collection interval of the area in which the measurement terminal is present, the collection time of this area, the slot count of this area, and the slot No. allocated to the measurement terminal, and receives measurement information including measurement data measured on the basis of the collection interval and the collection time, from each of the measurement terminals to which slot Nos. are allocated.

Multiple addressing facsimile system

An automatic head gap adjustment device for a printer has a plunger that protrudes beyond the print head toward the platen, a linear transducer that detects the amount by which the plunger is depressed, and a motor for widening and narrowing the head gap by moving the print head or platen. A controller drives the motor forward, narrowing the head gap, until the signal output by the transducer changes by a certain amount, then drives the motor in reverse for a fixed amount, widening the head gap, then preferably drives the motor forward again by a smaller fixed amount to take up play in the drive mechanism. This device adjusts the head gap accurately despite changes in ambient conditions.

A ticket processing terminal device includes a hopper to store medium that is to become prescribed tickets, a separation and pick-up section for separating and picking up one sheet of medium at a time from the hopper, a stacker to store those of the tickets inserted through the insertion opening which are replaced by the medium, a print section for printing on the ticket that has been inserted through the insertion opening or the medium picked up from the hopper, and is to be discharged through a discharge opening, a transport path to transport the tickets and medium between the above mentioned component elements, and a ticket information reader for magnetically or optically reading the information that has been given to the ticket, and a magnetic write section disposed along the transport path for writing, erasing or rewriting on the magnetic stripe if the ticket inserted through the insertion opening or the medium picked up from the hopper has such a magnetic stripe. The terminal device can accept a plurality of tickets, temporarily store them, and subsequently reissue either modified versions of less than the original number inserted or a new medium to replace the plural inserted tickets.
