Abstract: This data providing method is carried out by a computer (460) built in a data processing system (1) which is designed to collect log information from electronic devices through a network (30) and provide services based on that log information for authenticated users. The method includes: receiving a fridge's (100a, 100b) log information through the network; generating display data, representing a trend of change of a recovery time that indicates how long it takes for the fridge's inside temperature to recover a preset operating temperature since the fridge's door was closed, by reference to pieces of information which are included in the fridge's log information and which indicate (i) the preset operating temperature inside the fridge, (ii) the temperature of the ambient surrounding the fridge, (iii) a temperature inside the fridge, and (iv) opening and closing history of the fridge; and providing the display data for an authenticated user's display terminal (130a, 130b).

Abstract: A device monitoring method includes: receiving a message transmitted from a first device to a second device and addressed to the second device; determining whether the message contains a device control command for controlling the second device; if the message contains the device control command, further determining whether to transmit the message to the second device based on a predetermined condition; and when the message is determined to be transmitted to the second device, transmitting the message to the second device. The predetermined condition includes a first condition that the first device is registered as a device having a predetermined function in a device list containing information about whether each of the devices is a device having the predetermined function. The message is determined to be transmitted to the second device when the predetermined condition is satisfied.

Abstract: An abnormality detection apparatus for a mobility entity and for detecting an abnormality in a network system is provided. The network system includes a first network and a second network that use different communication protocols. A first communication circuit receives state information indicating a state of the mobility entity. The state information is acquired from the second network. A second communication circuit transmits and receives a first frame according to a communication protocol used in the first network. A memory stores an abnormality detection rule. A processor detects, based on the state information and the abnormality detection rule, whether a control command included in the first frame received by the second communication circuit is abnormal. In a case where the control command is abnormal, the processor prohibits the control command from being transmitted.

Abstract: An electronic control unit (ECU) is provided. The ECU is connected to a first network in an onboard network system. The onboard network system includes the first network and a second network. In the first network, first-type frames are transmitted following a first communication protocol. In the second network, second-type frames are transmitted following a second communication protocol. The first-type frame includes first information serving as a base for the second-type frame to be transmitted to the second network, and second information indicating that the first-type frame includes information that is to be transmitted to the second network. The ECU includes a generator that generates the first-type frame following the first communication protocol, and a transmitter that transmits, to the first network, the first-type frame generated by the generator.

Abstract: A network system includes a first network through which a frame of a first type is transmitted in accordance with a first communication protocol and includes a second network in which a frame of a second type is transmitted in accordance with a second communication protocol. A gateway device is connected to the first network and the second network. The gateway device sequentially receives frames of the first type from the first network and determines whether to transmit data regarding the received frames of the first type to the second network. The gateway device transmits, to the second network, a frame of the second type including data regarding a plurality of the frames of the first type determined to be transmitted to the second network when a condition relating to a number of frames of the first type received by the gateway device is satisfied.

Abstract: An abnormality detection method is provided. The abnormality detection method is for detecting an abnormality that may be transmitted to a bus in an on-board network system. The on-board network system includes a plurality of electronic controllers that transmit and receive messages via the bus in a mobility entity. In the abnormality detection method, for example, a gateway transmits identification information to a server and receives a response determining a unit time. An operation process is performed using feature information based on a number of messages received from the bus per the determined unit time and using a model indicating a criterion in terms of a message occurrence frequency. A judgment is made as to an abnormality according to a result of the operation process.
