Abstract: In a torque sensor of a torque detection system, in a state where a torque is not generated, a first magnetic detector overlaps with one (e.g., N-pole) of a plurality of magnetic poles of a magnet when the one of the plurality of magnetic poles of the magnet is radially projected onto the first magnetic detector. A second magnetic detector overlaps with another one (e.g., S-pole) of the magnetic poles when the another one of the magnetic poles is radially projected onto the second magnetic detector. A motor control device calculates a sum of a value, which relates to a detected strength of a magnetic field detected by the first magnetic detector, and a value, which relates to a detected strength of the magnetic field detected by the second magnetic detector. The motor control device is configured to calculate a steering torque based on the sum.

Abstract: A battery monitoring system includes a monitoring unit that monitors a battery and a higher device that is provided with monitoring data obtained by monitoring of the battery by the monitoring unit and saves, by using a blockchain, at least part of specific information included in the monitoring data. The higher device includes a block generation unit that generates a new block including a hash value based on the at least part of the specific information and a last block linked at an end of the blockchain, and an external communication device configured to save, in a distributed manner in a plurality of external devices, the new block generated by the block generation unit. At least one of the monitoring unit or the higher device is provided with a data protection unit configured to ensure reliability of the monitoring data.
