摘要： An electromagnetic flowmeter using a square wave excitation method includes a differential amplifier which outputs a detection signal; an analog-digital converter which converts the detection signal into a digital detection signal; a timing control circuit which generates a sampling signal for sampling the digital detection signal; an calculation unit which executes a flow rate calculation process and a abnormality judging process at a same time. The flow rate calculation process acquires a flow velocity output signal by sampling the digital detection signal in a flat portion in a positive/negative excitation section. The abnormality judging process acquires a differential output signal by sampling the digital detection signal in a rising/falling portion in the positive/negative excitation section, and obtains a differential noise from the flow velocity output signal and a differential output signal, and judges abnormality of the exciting current by comparing a differential noise with a detection threshold level.

摘要： A headrest position adjustment device includes a capacitance sensor unit, and a drive motor unit. The capacitance sensor unit includes a plurality of electrode groups each configured by a plurality of sensing electrodes. The total electrode area of each of the electrode groups is switchable by a switching unit of a circuit unit between at least a total electrode area A and a total electrode area A+B. The total electrode area A is selected when the distance d between a head and a headrest is short, and the total electrode area A+B is selected when the distance is long. In this way, the sensitivity is changed depending on how long or how short the distance is. An estimated center position of the head is calculated based on capacitance values obtained, and thereby the position of the headrest is adjusted.
