  • Patent number: 10846234
    Abstract: A storage control system reads a data set from a storage apparatus if necessary in response to an I/O request. A data set contains data and an address. The storage control system performs an all-type address check which is a check to determine whether one of a first address and second address which correspond to a read-target data set in address translation information, which is information indicating a mapping relationship between one or more first addresses and one or more second addresses, matches the address among the data and address contained in the data set. The one or more first addresses are each an address which belongs to the first address type. The one or more second addresses are each an address which belongs to the second address type. The storage control system performs processing according to the I/O request when the result of the all-type address check is true.

  • Publication number: 20200353821
    Abstract: A battery monitoring device includes temperature detectors that detect respective temperatures of battery elements in a battery of an electric vehicle. The temperature detectors each include first and second detection circuits, a comparator circuit, and first and second output terminals. The first detection circuit detects a temperature in a first temperature range and generates a first detection signal. The second detection circuit detects a temperature in a second temperature range and generates a second detection signal. The comparator circuit compares a detection output signal with a threshold and generates a flag signal indicative of the presence or absence of an abnormal event. The detection output signal and the flag signal are outputted through a first output terminal and a second output terminal, respectively. Each of the temperature detectors switches the detection output signal between the first detection signal and the second detection signal on the basis of the flag signal.
