The disclosure provides a mobile phone with function to acquire targeted message and method thereof. The piston and the cylinder body define a pressure chamber for generating hydraulic pressure. A tread piece having a channel shape with first and second side pieces projects substantially orthogonal to a connecting tread band. 0 and contains a component having a degree of substitution of 4 or less in an amount of 30-80% by mass. This particular current characteristic enables a voltage reference employing the current generator for high-order curvature correction to produce an output voltage whose variation is extremely flat over its industry standard operational temperature range. Depending on the required functionality, two or more satellite sensor modules are used, which measure multi-axis high-g and low-g acceleration, without needing any further sensor inputs like gyroscopes while achieving a high level of failsafe and redundancy.
