Methods and apparatus for separating, concentrating and/or detecting molecules based on differences in binding affinity to a probe are provided. The molecules may be differentially modified. The molecules may be differentially methylated nucleic acids. The methods can be used in fields such as epigenetics or oncology to selectively concentrate or detect the presence of specific biomolecules or differentially modified biomolecules, to provide diagnostics for disorders such as fetal genetic disorders, to detect biomarkers in cancer, organ failure, disease states, infection or the like.

Systems and methods for enhanced SCODA

A battery system includes a battery module that is constituted with a plurality of serially connected battery cells, a plurality of integrated circuits that group the battery cells so as to perform processing on battery cells in each group, a first transmission path through which a command signal is transmitted via a first insulating circuit from a higher-order control circuit that controls the integrated circuits to a highest-order integrated circuit of the integrated circuit, a second transmission path through which a data signal collected by the integrated circuits is transmitted from the highest-order integrated circuit to a lowest-order integrated circuit, and a third transmission path through which the data signal is transmitted from the lowest-order integrated circuit to the higher-order control circuit via a second insulating circuit.

Battery system in which information transmission occurs via insulating circuits

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.

Battery monitoring system

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.

Biomarker anaylsis using scodaphoresis

A battery system for a vehicle is provided with discharge circuits (RA throughD,A throughD) that discharge battery cells (BCthrough BC) via measurement lines of those battery cells (BCthrough BC). A control circuit transmits to an integrated circuit (A) a first discharge command that causes discharge of the odd numbered battery cells (BCand BC) of a cell group (GB), a first transmission command that causes transmission to the control circuit of the terminal voltages of only the odd numbered battery cells (BCand BC) measured during execution of the first discharge command, a second discharge command that causes discharge of the even numbered battery cells (BCand BC) of the cell group (GB), and a second transmission command that causes transmission to the control circuit of the terminal voltages of only the even numbered battery cells (BCand BC) measured during execution of the second discharge command; and, based on the these various terminal voltages transmitted from the integrated circuit (A), the control circuit diagnoses abnormalities in the system that includes the battery cells, the measurement lines, and the discharge circuits.

Battery system for vehicle

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.

Battery control device and battery system

A battery system includes: a battery unit formed by electrically connected in series a plurality of cell groups each made up with a plurality of battery cells electrically connected in series; a plurality of sensing lines for detecting voltages of respective battery cells in the battery unit; an integrated circuit provided to each of the cell group, to which the sensing lines for detecting voltages of respective battery cells in the cell group are connected; a case having housed therein a substrate at which a plurality of integrated circuits provided for the cell groups respectively are mounted; noise protection capacitors disposed between input terminals of the plurality of sensing lines; and at least one protection element against static electricity which is connected between the input terminals and the case.
