  • Encoder interpolator with enhanced precision
    Patent number: 8384570
    Abstract: A method is presented for converting the sine/cosine signals from an optical encoder into a high-resolution position signal for use by a position control system while eliminating common noise and error sources. The improved noise performance resulting from the alias-free demodulation of encoder signals improves precision and reduces power consumption in precision motion control applications. The adaptive compensation of harmonic distortion eliminates errors related to offset, gain and quadrature of the encoder channels. The interpolator is able to process encoder signals at extremely high resolution without the speed limitation of prior art encoder interpolators.

  • Radio-controlled adjustment timepiece
    Patent number: 8385156
    Abstract: A start date and an end date of a daylight saving time input by a user is stored in the daylight saving time information storage unit (41). The radio-controlled adjustment section (20) generates a time to adjust the time which the clocking unit (10) is clocking, by daylight saving time information and a standard time received via an antenna (AT) and a reception circuit (21), and adjusts the time of the clocking unit (10) by use of the generated time. Here, the daylight saving time determination unit (42) references to the daylight saving time period stored in the daylight saving time information storage unit (41), and adjusts the time of the clocking unit (10) so that the time becomes one which corresponds to the user-set daylight saving time.
