Abstract: A vehicle power supply apparatus includes a power converter circuit, a power storage unit, and a processor. The power converter circuit converts a voltage of electric power received from a normal power supply of a vehicle configured to perform idle-stop operation, and supplies the converted electric power to vehicle loads of the vehicle. The power storage unit is coupled to the power converter circuit. The vehicle loads include a first vehicle load related to travel of the vehicle and a second vehicle load not related to the travel of the vehicle. At an end of the idle-stop operation, the processor supplies the converted electric power to one of the first vehicle load and the second vehicle load, and supplies electric power from the normal power supply to the other of the first vehicle load and the second vehicle load.

Abstract: An onboard battery includes a battery module, a housing case, and a detector. In the battery module, a battery cell is disposed. The housing case has a through hole and houses the battery module. The detector includes a fixture portion fixed to the battery module and an elastically deformable portion that is elastically deformable. When an impact is applied and the battery module and the detector are displaced relative to the housing case by a certain amount or larger, the elastically deformable portion is elastically deformed to pass through the through hole.

Abstract: In a signal measurement device, a plurality of mixers output a signal having a frequency equal to a difference between two input frequencies, and a single local signal source feeds a common local signal input to the plurality of mixers. A difference measurement unit measures a level and a phase difference between outputs of the plurality of mixers if a common correction signal input is fed to the plurality of mixers, and a level/phase measurement unit measures the level and the phase of the output of the plurality of mixers if inputs of signal to be measured common in frequency are fed to the plurality of mixers. A difference correction unit corrects a measurement result of the level/phase measurement unit based on a measurement result of the difference measurement unit if a common input of signal to be measured is fed to the plurality of mixers.
