Abstract
A notification appliance is disclosed that includes a light engine for generating light flashes at a predetermined interval, an energy store for supplying energy to the light engine to generate the light flashes at the predetermined intervals and a charge controller for charging the energy store to a full charge level required to generate the light flashes. The charge controller controlling an input current to charge the energy store to reach the full charge level at the predetermined interval.
Claims21
A notification appliance comprising:
- a light engine for generating light flashes at a predetermined interval;
- an energy store for supplying energy to the light engine to generate the light flashes at the predetermined interval;
- and
- a charge controller for charging the energy store to a full charge level required to generate the light flashes, the charge controller controlling an input current to charge the energy store to reach the full charge level at the predetermined interval.
An energy discharge device comprising:
- a discharge component generating a high energy event at a predetermined interval;
- an energy storage device for supplying energy to the discharge component to generate the high energy event at the predetermined interval;
- and
- a charge controller for charging the energy storage device to a full charge level required to generate the high energy event, the current controller controlling an input current to charge the energy store to reach the full charge level at the predetermined interval.
A method of charging an energy store of a notification appliance, the method comprising:
- determining a predicted input current required to recharge an energy store at a predetermined interval with a feed forward model of a current controller based on nominal operating values of components of the notification appliance;
- generating a correction value with an adaptive feedback loop of the current controller for adjusting the predicted input current based on deviations from the nominal values of the components of the notification appliance;
- and
- charging the energy storage device to reach a full charge level at the predetermined interval.
