摘要:
A wearable electronic device for conveying information in an analog manner at least in part by the use of at least one display hand positioned on the dial side of a dial, wherein the wearable electronic device uses the display hand(s) to convey information that is stored in the controller of the device and/or provided by sensors and/or an external transmitter. An actuation mechanism, preferably a stepper motor, is used to rotate the display hands in the clockwise and/or counterclockwise directions in predefined increments to convey the information.

A switching mechanism is provided for a multimode electronic timepiece having a casing, a device for indicating a time-of-day and an integrated circuit operable in a plurality of modes. The switching mechanism includes a setting stem mounted for rotational movement and positionable in a plurality of axial setting positions. The setting stem includes at least one tooth. The switching mechanism also includes a switch arm having a first end, a second end and an intermediate portion. The intermediate portion engages the tooth of the setting stem. The switching mechanism further includes a first and a second electrical contact. When the setting stem is in at least one of the axial setting positions and while the timepiece is operating in at least two of the modes, the intermediate portion cooperates with the tooth to intermittently form, in response to a rotation of the setting stem, an electrical connection between the second end and, when the setting stem is rotating in a first direction, the first electrical contact to produce an intermittent first electrical pulse. Alternatively, when the setting stem is rotating in a second direction, an electrical connection is intermittently formed between the second end and the second electrical contact to produce an intermittent second electrical pulse. In one embodiment, the intermittent first and second electrical signals are inputs to setting functions performed within at least one of the modes of the timepiece.

In a hair treatment device with a winding mandrel driven by a motor and used to wind up hair, the current used by the motor is led through a current limiter circuit in order to limit torque. The current limiter circuit comprises an operating stage and a safety stage. The safety stage is utilized to limit current if the operating stage fails.

The invention relates to an electric watch, wherein the rotor of a stepping motor is arranged between the metal frame and the plastic frame and is mounted in bearing holes of these frames or base plates. In accordance with the invention, the plastic frame has adjacent to the bearing hole of the rotor a partially cylindrical web extending substantially perpendicular to the metal frame and penetrating the air gap between the rotor and the stator of the stepping motor, while the stator with the associated coil is mounted on the outer side of the plastic frame. This construction enables assembly of the rotor without the effects of disturbing magnetic interaction between rotor and stator tending to dislocate the rotor.

A method of calibrating a display hand in an electronic device. The preferred method comprises the steps of initializing a counter; stepping the rotor of the stepping motor a predetermined number of steps in a first direction and incrementing the counter; determining whether the counter is less than a predefined value representing at least the total of (i) the maximum number of steps needed from a zero position on the display to the maximum value on the display; and (ii) the number of steps needed from the zero position on the display to the position such that a channel formed in one of the one or more gears would abut against a tab; and if so, stepping the rotor of the stepping motor the predetermined number of steps in the first direction, incrementing the counter and again determining whether the counter is less than the predefined value; and if not, rotating the rotor of the motor in a direction opposite the first direction the same number of steps needed from the zero position on the display to the position such that the channel would abut against the tab. Several calibration assembly constructions are also provided.

In an electronic device, a method of measuring an external field and displaying indicia related to the measurement, wherein the electronic device generates a first internal field and at least a second internal field, wherein the method includes the steps of measuring the external field when the electronic device is generating the first internal field; and only displaying indicia related to measurements taken while the electronic device is generating the first internal field. In the preferred embodiment, the first internal field is generated by a rotor of a stepping motor being in a first orientation, and the at least second internal field is generated by the rotor of the stepping motor being in a second orientation, wherein the method includes the steps of determining whether the rotor is in the first orientation before measuring the external field; and if not, causing the rotor to rotate into the first orientation prior to measuring the external field.

In a wristwatch movement with a stepping motor with a rotor connected to drive a gear train which periodically advances the hands of the wristwatch, the stepping motor has a flat stator piece secured in a plastic movement frame. A coilcore assembly comprising a flat hook-shaped core plate having a straight core portion of uniform width with a coil inserted over the free hand of the core portion is secured to the stator so that opposite ends of the hook-shaped member overlap opposite ends the stator to complete a path for the magnetic flux. The hook-shaped coil core is placed on top of the stator during assembly and is held down by insulated clamping means such as a bridge or circuit board bolted to the frame at the time of final assembly. Preferably, the stator and coil core member are located with respect to one another by plastic studs integral with the frame extending through aligned holes in the stator and coil core. Some of the studs receive bolts which hold the clamping means to the frame.
