Abstract

A repair device for measurement, sampling device and waveform analysis device, which can analyze the waveform which is sampled from an output signal of a sensor, is provided to restrict the power consumption of the repair device for measurement. A repair device for measurement comprises an acceleration sensor(44) and a control member. The acceleration sensor outputs the acceleration value showing the acceleration. The control member controls two measurement states and operation states. The control member has the first control member and the second control member. The first control member reiterates acceleration value capturing, a fixed captured value, and the relation of threshold value for a fixed time. The second control member determines that the walk of the step using the acceleration value of the fixed number and the acceleration value from the acceleration sensor.

Description

【Technical field】 [0001] The present invention relates to a pedometer built in a mobile phone or the like, or a technique for sampling an output signal of a sensor and performing waveform analysis. 【Background technique】 [0002] Among the mobile phones, there are types that have a function as a step counting device for measuring the step count of the wearer of the mobile phone in addition to the original function of the mobile phone. In a mobile phone having a function as a step counting device, an acceleration sensor that detects the acceleration generated in the mobile phone according to the walking of the wearer is built in, or the walking of the wearer is detected by using the output signal of the acceleration sensor. circuit, etc. Therefore, a mobile phone having a function as a step counting device consumes more power than a mobile phone not having this function. JP-A-2010-15414 and JP-A-2009-300329 disclose techniques for suppressing power consumption of such mobil...
