Claim Text:
1. A phase estimating device comprising: a computer including a processor; a hardware interface configured to obtain a first periodic signal; and hardware storage, the computer being configured to control the phase estimating device to perform operations including: synchronizing a reference time with that of a signal generating device by wirelessly communicating with the signal generating device that outputs a second periodic signal according to phase information; storing, in the hardware storage, the reference time synchronized with that of the signal generating device; obtaining a sampled time from the hardware storage at a timing at which the first periodic signal rises above or falls below a predetermined level, and determining a phase information on a phase of the first periodic signal based on the obtained sampled time and period information on a period of the first periodic signal; and transmitting the phase information to the signal generating device.
