A timepiece movement is provided, including a first regulating member and a first escapement associated therewith; a first train connecting the first escapement to a first energy source; a second regulating member and a second escapement associated therewith; a second train connecting the second escapement to a second energy source; a display of a current time; at least one differential gear including a first input wheel meshing with the first train and a second input wheel meshing with the second train, the at least one differential gear driving the display, where the second regulating member consumes less energy than the first regulating member.

Computer-processor controlled energy harvester system optimized for use on mobile platforms. The system uses a plurality of oscillating weight type energy collectors, each configured to store the energy from changes in the system's ambient acceleration as stored mechanical energy. The energy collectors are configured to move between a first position where the energy collector stores energy, to a second position where the energy collectors release stored energy to a geared electrical generator shaft, thus producing electrical energy, often stored in a battery. A plurality of processor controlled electronic actuators control when each energy collector stores and releases energy. The processor can use battery charge sensors, and suitable software and firmware to optimize system function. To facilitate use on mobile platforms, the processor also uses input from a 3-axis accelerometer to dynamically reconfigure the energy collectors according to the present major directions of ambient acceleration.

A mechanical horological movement (1) including at least one barrel system (2) for driving a set of wheels and power reserve detector. The detector (10) includes a control wheel (3) disposed opposite the cage of the barrel system (2) and is rotated by a complementary wheel (8) at the differential output to determine a power reserve level. An aperture (13) has a first end (21) to define a complete charge of the barrel system and a second end (22) to define a complete discharge. A lever (4) is rotatably mounted about a lever axis parallel to the axis of rotation of the control wheel. A contact element (5) disposed in the aperture contacts the second end during a zero power reserve indication. A portion of the lever contacts a component of the movement to stop its operation when power reserve indication is at zero.
