  • Patent number: 11152877
    Abstract: A method for determining an error in the angular position measurement of a timepiece motor having one or more phases, including: detecting (3) each instant (14) when the value of one of the back electromotive forces is zero, storing (4) a time corresponding to each detected instant, measuring (5) several time intervals between two instants (14) detected in the same revolution of the motor, comparing (6) the measured time intervals to reference time intervals to deduce the reference intervals to which they correspond, and determining (7) an angular position measurement error if the measured intervals do not correspond to the expected reference intervals. The invention also relates to a method for correcting the angular position measurement. Also, a determination and correction system for implementing the methods and a timepiece including such a system.

  • Patent number: 9310773
    Abstract: An analog electronic timepiece includes a stepping motor, a gear train mechanism having gears, a pointer, a drive control unit, a control content changing unit, and a pointer position adjustment unit. If an operational command to rotate the pointer to a different moving target position is obtained while an operational control for rotating the pointer to a certain moving target position is in progress, the control content changing unit terminates the control and changes a control content to an operational control according to the command. If the reverse rotation driving operation is being performed, the pointer position adjustment unit performs an adjustment operation for removing shifting between a predicted position of the pointer and an actual position of the pointer which occurs because of rotational input from the stepping motor not being transmitted to the pointer due to gaps relating to the mesh of the gears.

    Abstract: When recovering power from a motor driver, a forward voltage across a parasitic diode can reduce the recovery efficiency, and control of a power recovery operation can take an unnecessarily long time. In order to address this problem, the power recovery operation is performed as follows without being affected by a parasitic diode: near a peak position of a waveform of an induced current resulting from free oscillation of a rotor after a drive pulse is output, a recovery pulse having such a level that the rotor does not rotate is output from a terminal different from a motor driver terminal to which the drive pulse was output. Also, by adjusting the width and output timing of the recovery pulse based on a power supply voltage, the power recovery can be optimized for the power supply voltage.

  • Publication number: 20140071795
    Abstract: A rotation detection circuit detects an induced current flowing through a drive coil of a stepping motor in a detection section divided into a plurality of sections, and detects a rotation state of the stepping motor on the basis of a pattern indicating whether or not the induced current exceeds a predetermined reference value in each of the sections. A control unit selects a drive pulse corresponding to the rotation state detected by the rotation detection unit, and supplies a drive current to a drive coil to rotatably drive the stepping motor. The rotation detection unit carries out detection by selecting a detection direction of the induced current in the sections after the first section on the basis of whether or not the induced current exceeding each of a plurality of reference values is detected plural times in the first section.

  • Publication number: 20140064040
    Abstract: An analog electronic timepiece includes a stepping motor, a gear train mechanism having gears, a pointer, a drive control unit, a control content changing unit, and a pointer position adjustment unit. If an operational command to rotate the pointer to a different moving target position is obtained while an operational control for rotating the pointer to a certain moving target position is in progress, the control content changing unit terminates the control and changes a control content to an operational control according to the command. If the reverse rotation driving operation is being performed, the pointer position adjustment unit performs an adjustment operation for removing shifting between a predicted position of the printer and an actual position of the pointer which occurs because of rotational input from the stepping motor not being transmitted to the pointer due to gaps relating to the mesh of the gears.

  • Patent number: 8526272
    Abstract: A day clock has day, hour, and minute hands revolving continuously around a common center. It has a time adjustment knob and a day adjustment knob. When the day adjustment knob is pulled out, a set of gears are disengaged, allowing the day hand to be adjusted with that knob without affecting the other hands. Then, when the set of gears are reengaged, the time adjustment knob can be utilized to set the time of day. In order to set the day and time accurately, the user may first set the time to midnight with the time adjustment knob, pull out the day adjustment knob, set the day to a clock face line between days with that knob, push that knob back in, and then set the time to the correct time with the time adjustment knob.
