Abstract: An objective is to provide a lifetime prediction system that allows a highly reliable lifetime prediction even when record of events having occurred in products are inaccurate. A lifetime prediction system 1 includes a server device 5 that predicts a lifetime of a product as a machine such as a work machine 2 or a machine part. The server device 5 includes an operation information database 52 that stores operation information for each of a plurality of products, a history information database 53 that stores history information indicating a history of event data as a record of an event having occurred in each of the plurality of products and an arithmetic processing device 54 that predicts the lifetime of the product.

Abstract: The present disclosure provides a parameter selection device for a work machine that enables the work machine to efficiently travel at a work site where a travel route or a slope changes from moment to moment. The parameter selection device includes a parameter selection section. The parameter selection section calculates an average loaded travel distance per cycle, a travel ratio for each slope in loaded travel, and a virtual travel distance for each slope per cycle of the work machine (processing P1-P3). Further, the parameter selection section calculates a predicted fuel consumption amount for each slope per cycle, a travel time for each slope per cycle, a predicted fuel consumption amount per unit load weight, and a predicted production amount per cycle (processing P4-P8). Then, the parameter selection section selects a recommended parameter set, based on the predicted fuel consumption amount and the predicted production amount per cycle for each parameter set (processing P9).

Abstract: A malfunction prediction system 1 includes: an operation data acquisition section 201 that acquires operation data of a hydraulic excavator 10; an inspection data acquisition section 202 that acquires inspection data of the hydraulic excavator 10; a part replacement/repair data acquisition section 203 that acquires part replacement/repair data of the hydraulic excavator 10; and a malfunction prediction section 205 that predicts a malfunction probability of each part of the hydraulic excavator 10, based on the operation data acquired by the operation data acquisition section 201, the inspection data acquired by the inspection data acquisition section 202, and the part replacement/repair data acquired by the part replacement/repair data acquisition section 203.

Abstract: It is provided a motion line processing system, which can access motion line information including a history of movement of a person, event definition information including a condition for determining an occurrence of an event in a predetermined region, and transaction information including information of transaction of a product, comprising: an event information creation unit configured to analyze the motion line information with reference to the event definition information, and create event information including a start time of the event, an end time of the event, and identification information of a person who has caused the event; and an association processing unit configured to compare the event information with a transaction date/time, and associate the motion line information with the transaction information in a case where the transaction date/time is included between the start time and the end time, and the event is a transaction event at a transaction location.

Abstract: The sensor data collection system includes one or a plurality of sensors; a gateway device capable of collecting, converting, processing, making a threshold determination of, and compressing data from the sensors and transmitting the data to a data collection server at a timing set as needed; and the data collection server that collects the sensor data from the gateway device. The data collection server includes a means that compresses sensor data conversion, processing, threshold determination, compression, and transmission timing settings into a binary and transmits the binary to the gateway device. The gateway device includes a means that executes conversion, processing, threshold determination, and compression with respect to the data collected from the sensors in accordance with the various settings compressed into the binary, and that transmits the sensor data to the data collection server at the set transmission timing.

Abstract: Configuration information of a portable information terminal can only be changed by reliable applications. A ROM area stores a first inter-process communication function unit that partially constitutes a first administrative application having an administrative privilege and is capable of transmitting information to and from other applications, and an authentication application name that partially constitutes the first administrative application and is used to authenticate an application that is a source of transmission of information, and an application name, a shared name, and a signature of a second administrative application having no administrative privilege. A RAM area stores an application name, a shared name, and an ID of an installed application and is managed via an OS.

Abstract: Leakage of information stored in a mobile communication device via a network is prevented. To this end, a mobile communication device that together with an authentication server forms part of a network system is equipped with: a functional unit configured to detect a change in information on the physical location of the device itself and/or information on the location of the device itself on a network; a functional unit configured to, upon detection of the change, transmit to the authentication server the information on the location of the device itself and/or the information on the location of the device itself on the network; and a functional unit configured to receive from the authentication server a communication control policy corresponding to the information on the location of the device itself and/or the information on the location of the device itself on the network, and apply the communication control policy to the device itself.

Abstract: A player has the function of viewing contents on an in-house network, without installing software in the player. A gateway apparatus mediating between the in-house network and the Internet is provided with a mediation program; the in-house network or the Internet is provided with a conversion server; the mediation program acquires a contents list from an Internet dynamic-image site and converts the contents list to a data format displayable by the player; the player displays the contents list to enable a user to make a selection; the mediation program transfers, to the conversion server, a contents acquirement request selected from the contents list displayed in the player; the conversion server acquires a dynamic image from the dynamic-image site, converts the dynamic image to a format regenerable by the player and transmits it to the player via the gateway apparatus; and the player regenerates the received dynamic-image data.
