Accordingly, the overall size of the unit can be reduced where the unwinding spring charges an auxiliary battery for just a short duration. This is enough to make emergency calls, send messages or photos before the phone dies again. It can be restarted by winding the spring again to generate power for another short duration. The point of this is to reduce the size and weight of the charger so that it can be integrated into the device in question.
  • mechanical input created by actuating the actuator is converted into an electricity supply by a miniature dynamo system which charges a small battery. Accordingly, the mechanical energy created by the actuation of the actuator or crown is converted by a dynamo to induce a direct current which is then transferred to the battery. The actuation charges the battery for a limited time period. The electricity supply stops soon after actuation is stopped. This gives short bursts of energy to power a dead phone or a watch for a limited duration of time.
  • turning the crown repeatedly creates a dynamo like system providing an electricity supply. This can be done while the watch is running or after it has stopped. In other words turning the crown winds the mainspring and charges the battery (used for rewinding the mainspring). In purely digital watches without a mainspring, winding the crown could charge a battery to run the functions of the watch. Accordingly various types of actuators can be used which when operated (rotation, sliding, rocking etc.) would initiate a dynamo type of system providing a short duration electricity supply to charge a small battery. Repeated actuations would charge it fully. Battery level indicator would indicate when to stop actuating.
  • the electronic or computer controlled winding and unwinding can be used purely for watches as well. Accordingly, every time the watch is nearly completely unwound, a sensor and electronic circuit can initiate a computer controlled rewinding. An auxiliary rechargeable battery can drive this. When the mainspring unwinds, in addition to running the watch functions, it also generates a small electricity supply to charge this auxiliary rechargeable battery. By the time the mainspring is nearing its end cycle, the auxiliary battery is fully charged to drive the electronic rewinding of the mainspring.
  • the winding can be initiated by the touch or swipe gesture from the digital watch screen.
  • the option of winding the watch with a crown also exists, wherein in addition to the spring winding, the rechargeable battery also gets charged by this manual winding.
  • the unwinding spring also charges the battery in one of its functions.
  • manual winding also charges the battery with an independent or integrated system.
  • the spring starts getting wound and this causes the watch to start running and the auxiliary battery to start charging because one of the functions of the unwinding spring is to charge the battery in addition to driving other watch functions.
  • the mechanical activation could be a feather touch type or flat type press button type.
  • the power spring generator of the invention is controlled through a digital interface, that is, the winding and unwinding of the power spring is controlled through a digital interface.
  • the said digital interface includes, but is not limited to, a device screen glass or watch faces or watch edges.
  • the charging function can be initiated from the device digital screen interface using touch/swipe gestures through computer hardware and software control systems. Said digital interface could be on the edge of the watch where physical crown might exist.
  • the gesture control may include a winding motion created by forefinger and thumb (Fig. 5) and also circular winding motions created by forefinger in general direction of device.
  • the gesture is without actually physically touching the device.
  • the gesture can be used wherethe virtual crown C sits on the watch (W) edge/side. It can also be used on the watch caseback or watchface to initiate and control winding.
