A non-transitory computer readable storage medium has instructions executed by a processor to compute an x-axis axial position based upon a first host border measurement signal, a second host border measurement signal, first x-axis axial measurement signals and second x-axis axial measurement signals. A y-axis axial position is computed based upon the first host border measurement signal, the second host border measurement signal, first y-axis axial measurement signals and second y-axis axial measurement signals. A z-axis axial position is computed based upon the first host border measurement signal, the second host border measurement signal, first z-axis axial measurement signals and second z-axis axial measurement signals. The operation of a computer numerical control milling machine is coordinated based upon the x-axis axial position, the y-axis axial position and the z-axis axial position.

An electronic apparatus includes a communication unit configured to perform wireless communication, a storage, a first determiner, and an indoor specifying unit. The storage stores therein, as registered identification information, identification information whose contents are changeable, the identification information being allocated to a first communication device with which the communication unit is capable of performing wireless communication. The first determiner determines whether received identification information agrees with the registered identification information, the received identification information being the identification information received by the communication unit from a second communication device and allocated to the second communication device. The indoor specifying unit performs indoor specification to specify that a user having the electronic apparatus is indoors, based on a first result of determination by the first determiner.

An abnormality diagnosis apparatus includes: a model acceleration calculation unit to calculate model acceleration that is a predicted value of motor acceleration; a motor acceleration calculation unit to calculate the motor acceleration from one of position information and speed information on a motor; and an abnormality determination unit to diagnose whether a power transmission mechanism is abnormal on the basis of the result of comparison between the motor acceleration and the model acceleration.

An opening/closing member driving device includes a motor that opens and closes an opening/closing member and a controller configured to perform an abnormality determination process and a masking process. The abnormality determination process determines occurrence of a foreign object being entrapped or caught by comparing driving information corresponding to a driving status of the motor to a predetermined threshold value. The masking process invalidates the abnormality determination process over a predetermined masking period when the motor is activated. The controller includes a correction unit. The correction unit corrects at least one of the masking period or the threshold value when the motor is activated in a direction opposite to that of a preceding operation in a state in which the opening/closing member is in a high-load range.
