Abstract: To measure a walking pitch or a running pitch more accurately with a simpler structure. Acceleration sensors detect accelerations and output acceleration signals corresponding to the accelerations. A CPU detects a cycle in which a user touches the ground at the time of walking or running based on the acceleration signal and calculating a first pitch based on the cycle of touching the ground. The CPU also detects a cycle in which the user swings his/her arms based on the acceleration signal and calculates a second pitch based on the cycle of swinging arms. The CPU determines either one of the first pitch and the second pitch which satisfies a given condition as a walking or running pitch of the user.

Abstract: A stepping motor control device is configured to drive a stepping motor by applying a normal drive pulse or a fixed pulse having an energy larger than that of the normal drive pulse. The stepping motor control device includes a determination unit configured to, based on whether or not a pulse applied to the stepping motor before the normal drive pulse is the fixed pulse, determine whether or not to add a degaussing pulse is applied to the normal drive pulse, the degaussing pulse being a pulse for canceling a residual magnetic flux generated in a stator of the stepping motor when the fixed pulse; and a drive control unit configured to, based on a determination result of the determination unit, drive the stepping motor with the normal drive pulse to which the degaussing pulse is added.

Abstract: A timepiece movement includes a control unit that determines a position of an indicating hand by detecting a rotation state of a rotor, and a train wheel that transmits a drive force of a stepping motor to the indicating hand, and that has a first gear, and a second gear and a third gear which mesh with the first gear. The first gear has a reference load unit that causes fluctuations in a load applied to the rotor in each case of meshing with the second gear and the third gear. A first line segment which connects a center of the first gear and a center of the second gear to each other forms an angle smaller than 180° with a second line segment which connects the center of the first gear and a center of the third gear.
