Latest Patents

One of Grandjean's latest patents is a method and device for controlling a bidirectional stepping motor. This invention focuses on a method for controlling a bidirectional stepping motor that has two windings and three pole faces. The technique involves applying current pulses alternately to one of the motor windings to rotate it in one direction and to the other winding to rotate it in the opposite direction. This invention is particularly useful for controlling bidirectional motors used in timepieces.

Another significant patent is a touch-sensitive device for a timepiece. This device is designed to control a function of a timepiece and features a condenser with a capacity that is independent of the area touched by the user. A conductive stem is fixed within the timepiece case and is insulated from it by a mounting member. The head of the stem, located outside the timepiece, forms one of the condenser electrodes. A thin layer of insulating material covers the head, creating the condenser dielectric. When the second electrode is energized by user touch, the entire electrode is activated, regardless of the area touched, providing a unique user experience.
