Publication number: 20160026153Abstract: The timepiece comprises means for indicating the sunrise and sunset taking into account seasonal variations (17, 27). These means comprise a sphere (17) representing the Earth, a shell (27) arranged concentrically to the sphere and arranged to delimit a part of the globe where it is night time from another part where it is daytime by indicating the position of the Earth's terminator. The shell can pivot around the globe along two perpendicular axes (X-X, Y-Y). The shell is driven by the movement in order to revolve at the rate of one revolution every 24 hours around the polar axis (X-X). A differential mechanism (50) is controlled by a year cam (72) that has a profile representing the inclination of the sun in relation to the equatorial plane. The differential mechanism controls the inclination of the shell around the axis (Y-Y) by means of a drive shaft (35) concentric to the polar axis (X-X).Type: ApplicationFiled: July 9, 2015Publication date: January 28, 2016Applicant: The Swatch Group Research and Development Ltd.Inventors: Beat GILOMEN, Michel WILLEMIN, Dominique LECHOT

Patent number: 9188957Abstract: A single electronic module includes a autoregulating circuit that regulates an oscillation frequency of an oscillating mechanical system, such as a balance having a balance spring. A piezoelectric element is mounted on the oscillating balance spring and connected to the autoregulating circuit to generate an alternating voltage. The autoregulating circuit rectifies the alternating voltage and regulates the alternating voltage frequency. The rectified voltage is stored in a capacitor to power the autoregulating circuit. The autoregulating circuit includes an oscillator connected to a mirco-electro-mechanical system (MEMS) resonator that supplies a reference signal, and compares the frequency of the alternating voltage to the reference signal frequency. The autoregulating circuit supplies frequency adaptation signal to the piezoelectric element according to the result of the comparison, in order to regulate the oscillation frequency of the balance.Type: GrantFiled: October 23, 2012Date of Patent: November 17, 2015Assignee: The Swatch Group Research and Development Ltd.Inventors: Michel Willemin, Jean-Claude Martin
