Abstract: Device (400) for selecting a clock function from a rewinding function and m correction functions, m>1, comprising a control member (3), notably a staff, able to select the rewind function by movement of the control member in a first direction and to select sequentially one function from m correction functions by movement of the control member in a second direction.

Abstract: A growing amount of data is produced daily resulting in a growing demand for storage solutions. While cloud storage providers offer a virtually infinite storage capacity, data owners seek geographical and provider diversity in data placement, in order to avoid vendor lock-in and to increase availability and durability. Moreover, depending on the customer data access pattern, a certain cloud provider may be cheaper than another. In this respect is provided a method and a system that facilitates allocation of data objects in a distributed data storage environment. The system continuously adapts the placement of data based on its access patterns and subject to optimization objectives, such as storage costs. The system efficiently considers repositioning of only selected objects that may significantly lower the storage cost.

Abstract: At least some of the uniformly distributed teeth of one of the antibacklash partner toothed wheel units, of this backlash-compensating gear train for a horological mechanism, have elastic parts (DR) that are flexible in the direction of the respective thicknesses of the teeth. Some of the teeth are capable of temporarily transmitting a torque considerably greater than the normal drive torque. Two adjacent teeth (D1, D2) capable of temporarily transmitting a torque considerably greater than the normal drive torque each comprise one flank (D1a, D2a) integral with a more rigid part (D12), and one flank (D1b, D2b) integral with a more flexible part (D1R, D2R), the two more rigid parts (D12) of the two teeth (D1, D2) being adjacent.

Abstract: This timekeeper comprises a first timer (4), means (12) for connecting it selectively to the train of the timekeeper (T), a second timer (5), a synchronous coupling between the first (4) and second (5) timers, and fly-back means (13, 13?, 9, 11) for said timers (4, 5). An auxiliary motive source (10?) is in a driving relationship with the second timer (5) and a one-way coupling (6a, 7a) is situated between the first (4) and second (5) timers to regulate the speed of movement of the latter at a predetermined ratio with the speed of movement of the first timer (4) while allowing one-way relative movement of the first timer (4) relative to the second (5) when the latter is in the stop position and one-way relative movement in the opposite sense of the second timer (5) when the first timer (4) is in the stop position.
