The object of this invention is to produce a monitor which can correctly distinguish normal from abnormal vibration using automatically selected monitoring features and algorithms. The monitor can be used with a variety of devices with different vibration characteristics. The monitor according to this invention has a sensor that detects the vibration of an object. The monitor is operated in learning mode when the object is vibrating normally. The waveform of the vibration detected by this sensor is sampled over an appropriate period and analyzed. The data for each sampling feature are subjected to statistical processing, and the data which evince slight change are extracted as monitoring features. A monitoring algorithm is automatically made for these monitoring features. The algorithm selected in learning mode are used to evaluate the vibration of an object when the monitor is in operating mode. The operator does not need to set up the algorithm, and can monitor the object with a more reliable algorithm than the conventional one selected by fixed monitoring features.

A position reading apparatus and keyboard apparatus using a feedback loop for inputting positional information into an external device. A pointer having a resonant circuit is used to establish a feedback loop having as part of the feedback loop a first coupling device a second coupling device, an amplifier and the resonant circuit. When the resonant circuit approaches the first and second coupling devices electromagnetic coupling is established between the position pointer and the first and second coupling device. As a result, oscillation occurs at a resonant frequency of the resonant circuit establishing an oscillation signal. The oscillation signal information determines the position of the pointer. Switches are used to alter the resonant frequency of the resonant circuit.
