20140082427 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE AND MICROCONTROLLER - To have a problem of occurrence of the same failure in failure detection of a microcontroller. A microcontroller has a CPU and a data access control circuit. The data access control circuit performs two types of accesses: an individual access in which a data access of the CPU is performed for each thread, and a shared access in which a data access of the CPU is performed by executing two threads. The data access control circuit detects a failure of the CPU by making a comparison between the command and the address, respectively, in the shared access generated by executing the two threads. | 03-20-2014 |
20140098706 | COMMUNICATION CONTROL EQUIPMENT - Communication control equipment is connected to a plurality of communication control equipment via a network and is configured to be time-synchronized with the plurality of communication control equipment by using a time synchronization procedure using a communication including at least request packets and acknowledgement packets. The communication control equipment includes a receiving-interval measurement section configured to measure a receiving interval of request packets from the plurality of communication control equipment; and a queuing-occurrence determination section configured to detect conflict of the request packets from any of the plurality of communication control equipment on a basis of the receiving interval of the request packets measured by the receiving-interval measurement section. The communication control equipment is configured to determine whether to transmit an acknowledgement packet to the communication control equipment that has transmitted the request packets based on a detection result of the queuing-occurrence determination section. | 04-10-2014 |
20140114635 | Radio Wave Propagation Environment Measuring Apparatus, Radio Network Construction System, and Method For Measuring Radio Wave Propagation Environment - A method for measuring a radio wave propagation environment includes installing radio signal transmission and reception apparatuses where a radio network system is to be constructed and obtaining an electromagnetic wave measured value of a signal between transmission and reception apparatuses; estimating an electromagnetic wave propagation state of the signal using an electrical property and information on a three-dimensional structure at the site to obtain an electromagnetic wave estimated value; making a comparison between measured and estimated values for each time of day to determine when errors between measured and estimated values exceed a reference value; obtaining an electromagnetic path between transmission and reception apparatuses; and modifying structure information in the wave path to re-obtain the estimated value; and comparing the measured re-obtained estimated value to modify the three-dimensional structure information so that the error value becomes smaller. | 04-24-2014 |
20140362933 | ELECTRONIC CONTROL DEVICE - By reducing the serial transmission amount of pulses between a driving IC and a control IC, the transmission times of various commands other than the transmission time of the pulses can be secured, so that the improvement of reliability and high performance of the entirety of an electronic control device can be realized. The serial transmission between the driving IC and the control IC is started at the time when the edges of the pulses are detected. | 12-11-2014 |
20150046759 | SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE - A micro controller with fault detection function is provided, in which duplex processing by a program is realized without complicating the program. Peripheral circuits are provided with registers and execute processing based on a command. A central processing unit executes twice processing by the same program that accesses the register. A duplex access control circuit is configured with a peripheral bus access unit, a buffer, and a comparator unit. The peripheral bus access unit controls the access to the register by the central processing unit in the first program execution. The buffer stores the access information to the register in the first program execution. The comparator unit compares the access information in the second program execution with the access information stored in the access information storage unit. In the case of disagreement, an error signal is outputted to the central processing unit. | 02-12-2015 |
20150083844 | LABEL ISSUING DEVICE AND DETACHABLE CONTAINER - The label issuing device, which reels out linerless paper having an adhesive face on one side and cuts the reeled-out linerless paper to issue individual labels, has a cutter part for cutting the reeled-out linerless paper and a detachable container that is detachable from an enclosure of the label issuing device. The detachable container has a reservoir part for reserving a lubricant, and an application part that extends from the reservoir part, receives the lubricant reserved in the reservoir part, and applies the lubricant to a blade body of the cutter part. The reservoir part is filled with an impregnation material that is impregnated with the lubricant to hold (reserve) the lubricant, wherein the impregnation material is coupled to an impregnation material of the application part. | 03-26-2015 |
20150276416 | FLEET MANAGEMENT SERVER, ONBOARD TERMINAL EQUIPMENT, AND FLEET MANAGEMENT SYSTEM - A fleet management server is connected to onboard terminal equipments mounted on plural haulage vehicles. The server includes an operation mode determination unit and operation mode switching unit. The determination unit determines whether or not an operation mode, in which segment setting processing is performed to set travel-permitted segments for the vehicles, respectively, needs switching between a bidirectional mode and a push mode. In the bidirectional mode, the processing is performed to send response information upon reception of request information from each onboard terminal equipment. In the push mode, a travel-permitted segment setting unit, without reception of such request information, performs the processing for one of the vehicles to set a new travel-permitted segment, and produces and transmits travel permission information indicating the new travel-permitted segment. The switching unit performs switching processing of the operation mode according to the results of the determination. | 10-01-2015 |
20150295944 | CONTROL SYSTEM, CONTROL METHOD, AND CONTROLLER - In case a security abnormality has been detected in a control system, ensuring the safety of the control system is accomplished. In a control system including field equipment that executes a controlled process and a controller that controls execution of a controlled process by the field equipment, the controller detects a security abnormality in the control system and determines and executes a security countermeasure method against the security abnormality based on a status of a controlled process when the security abnormality has been detected in the control system. | 10-15-2015 |
