A method for the continuous non-invasive measurement of blood pressure includes at least one first pressure cuff and one second pressure cuff of comparable or identical size, each cuff including an inflatable pressure measuring chamber applicable to a first and a second body part or region containing an artery. In an engine restart under certain conditions, the control apparatus sets a motor output value for the electric motor to a value exceeding the rated performance. In the second needle portion, one end of a liquid passage is connected to the inside of the needle base portion, and the other end thereof is a liquid pass opening of the second needle portion. The auxiliary image capturer is disposed adjacent to the main image capturer. Copies of this patent with color drawings will be provided by the Patent and Trademark Office upon request and payment of the necessary fee. The each of a plurality of magneto-resistance effect elements have a pattern shape which substantially internally touches an ellipse having major and minor axes of the magneto-resistance effect element as major and minor axes thereof and a pitch between the adjacent magneto-resistance effect elements in a direction of the major axis is longer than that in a direction of the minor axis.
