  • Publication number: 20190152524
    Abstract: In a rotation detecting apparatus, each of first and second sensor elements measures rotation of a detection target. A circuit module includes first and second rotational angle calculators each calculating, based on a corresponding one of a first measurement value of the first sensor element and a second measurement value of the second sensor element, a rotational angle of the detection target. The circuit module includes first and second rotation number calculators each calculating, based on the corresponding one of the first measurement value and the second measurement value, a rotation number of the detection target. The circuit module includes first and second communicators each outputting, to a controller, a rotational angle signal based on the rotational angle and a rotation number signal based on the rotation number. A package packages the first and second sensor elements, and is mounted to a circuit board separately from the controller.

  • Publication number: 20190144028
    Abstract: A synchronization signal generating portion of a transmitter microcomputer generates a synchronization signal that is synchronized with a drive timing of the own microcomputer and also causes to synchronize the drive timing of microcomputers, and transmits to a receiver microcomputer. A timing corrector of the receiver microcomputer is capable of correcting the drive timing of the own microcomputer so as to synchronize with the received synchronization signal, and includes a timing determiner which determines whether the received synchronization signal is normal or abnormal. The receiver microcomputer permits the timing correction if the synchronization signal is determined to be normal in the timing determination, and prohibits timing correction and drives the motor asynchronously with the transmitter microcomputer if the synchronization signal is determined to be abnormal.

  • Publication number: 20190036972
    Abstract: A federated gateway bridges service definition formatting differences between a first and a second independent enterprise information technology (IT) management domain. A service request is received within the federated gateway from a service consumer application executing within the first independent enterprise IT management domain to a remote service provider application in the second independent enterprise IT management domain. The federated gateway dynamically performs real-time service call translation during transmission of the service request from a local service definition format to a remote service definition format defined respectively within the first and second independent enterprise IT management domains.

  • Patent number: 10177694
    Abstract: In a current sensor abnormality diagnosis device, an abnormality judgment section determines that the phase current sensors are operating normally when a sum of three phase currents is not more than a threshold value, and a bus current sensor is operating normally based on a comparison result between three phase currents and a bus current. The abnormality judgment section detects which the phase current sensor has failed based on the three phase currents and the bus current when the sum of the three phase currents is more than the threshold value. Because of using the comparison results of the three phase currents with the bus current in addition to the sum of the three phase currents, it is possible for the abnormality judgment section to detect the occurrence of abnormality of each of these current sensors even if the detected current has an undefined value.
