  • Patent number: 10202041
    Abstract: A battery monitoring system, comprises a battery state detection circuit that detects battery states of a plurality of battery cells that are connected in series, based on respective cell voltages of the plurality of battery cells, and a control circuit that monitors state of a battery cell, based on each cell voltage of the plurality of battery cells. The control circuit inputs pseudo voltage information to the battery state detection circuit, and thereby diagnoses whether or not the battery state detection circuit is operating normally.

  • Patent number: 9512477
    Abstract: The invention discloses methods and apparatus for characterizing trace nucleic acids that are biomarkers for disease. The methods and apparatus provide increased sensitivity to such trace nucleic acids, and allow analysis of nucleic acids present in a sample at only 0.01% of the wild-type sequences. The methods and apparatus are also designed for straightforward multiplexing, thus allowing pooling of clinical samples.

  • Patent number: 8829717
    Abstract: A battery control device for a battery module includes a plurality of integrated circuits. Each integrated circuit includes: a constant voltage circuit that lowers a total voltage of a battery cell group corresponding to the integrated circuit to an integrated circuit internal voltage; a signal generation circuit that generates, based upon a first signal provided by a higher-order control circuit, a second signal assuming a wave height value different from a wave height value of the first signal and outputs the second signal; and a startup circuit that includes a first comparator assuming a first decision-making threshold value corresponding to the first signal and a second comparator assuming a second decision-making threshold value corresponding to the second signal, and starts up the constant voltage circuit in response to a change in an output from at least either the first comparator or the second comparator.
