In a magnetic field measurement apparatus and a magnetic field measurement method provided herein, a magnetic field from an object is measured by a magnetic sensor group including a plurality of magnetic sensors. Then, an estimated value of a common noise component included in observed quantities of the magnetic sensors of all the channels of the magnetic sensor group is obtained as an external magnetic noise component. Finally the magnetic signal from the object is calculated by subtracting the estimated value from the observed quantity of each of the magnetic sensors.

Magnetic field measurement apparatus and method for noise environment

There is provided a magnetic noise rejection apparatus which includes: a plurality of cancellation coils arranged near a target object; a plurality of magnetic sensors disposed inside the respective cancellation coils; an adder circuit configured to take a sum of outputs of the plurality of magnetic sensors; and a feedback control circuit configured to supply the cancellation coils with such a common feedback drive current that the sum of the outputs of the magnetic sensors is equal to a sum of outputs of the magnetic sensors under a zero magnetic field.

Transmission and reception nodes are connected to a communication network to be controlled with respect to time according to bus time as time information shared therebetween. The transmission node periodically transmits data while keeping a predetermined free period of time. The reception node decides normality of data received. At detection of abnormality in reception, the reception node transmits during the free period of time a re-transmission request signal to the transmission node with specification of information identifying the bus time of the abnormal data reception. On receiving the re-transmission request signal, the transmission node obtains the data transmitted at the bus time identified by the information specified by the re-transmission request signal and then re-transmits the data during the free period of time to the reception node.
