Patent number: 10003301Abstract: The present invention concerns a drive circuit for driving an oscillator. The drive circuit comprises a first inductor comprising a first terminal and a second terminal; an electrical energy source connected to the first terminal; and a switching circuit connected to the second terminal and to the oscillator. The switching circuit is configured to operate at least in an off state, where it is configured not to feed electrical energy to the oscillator, and in an on state, where it is configured to feed electrical energy to the oscillator. The first inductor is arranged to store energy in its magnetic field when the switching circuit is in the off state, and, when the switching circuit is in the on state, the switching circuit is arranged to use at least some of the energy stored in the magnetic field to deliver a surge of current from the electrical energy source to the oscillator.Type: GrantFiled: September 20, 2016Date of Patent: June 19, 2018Assignee: The Swatch Group Research and Development Ltd.Inventor: Massimiliano Bracco

Patent number: 9537454Abstract: The electronic device is arranged for generation of an audible alarm or music. It includes a coil or inductor and a buzzer provided with a capacitor connected in series with the coil. When the electronic device is actuated, the buzzer generates the audible alarm or music. The electronic device further includes, in a feedback loop, a derivative circuit connected to a connection node between the coil and the capacitor, to produce a derivative of the signal from the capacitor, and a comparator for comparing a derivative signal from the derivative circuit with a reference voltage. The comparator supplies an output signal to the coil to amplify the signal across the capacitor, so that the buzzer generates at least one audible alarm.Type: GrantFiled: September 24, 2015Date of Patent: January 3, 2017Assignee: The Swatch Group Research and Development LtdInventor: Massimiliano Bracco
