Assignee: ASAHI KASEI MICRODEVICES CORPORATION
Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 10:
11. An event detection system comprising:
a magnetic-field generation unit configured to generate a predetermined magnetic field;
a multi-axis magnetic sensor for detecting a magnetic field flux density, generated by the magnetic field generation unit, in each axis of the multi-axis magnetic sensor; and
a processing unit configured to process a magnetic field flux density measurement signal generated for each axis of the multi-axis magnetic sensor, wherein the processing unit includes:
an obtainment unit configured to preset a position of an anticipated event relative to the multi-axis magnetic sensor;
a selection unit configured to select a detection axis, from among a plurality of axes in the multi-axis magnetic sensor, for detecting an occurrence of the anticipated event;
a calculation unit configured to calculate a trigger threshold value of the magnetic field flux density measurement signal of the selected detection axis at an occurrence of the anticipated event; and
an output unit configured to output a trigger signal indicating that the magnetic field flux density detected by the multi-axis magnetic sensor and the trigger threshold value meet a predetermined condition.
