UNINTERRUPTED POWER SUPPLY, ESPECIALLY FOR A REFRACTIVE LASER
First Claim
Patent Images
1. An uninterruptible power supply for a load with a rechargeable battery, whereby a device is provided to test the battery capacity, characterized by the fact that a device is provided that compares the capacity to the requirement of the load and transmits a signal to the load, which represents the result of this comparison.

Abstract
The invention concerns an uninterruptible power supply that is used in particular with a refractive laser. A rechargeable battery is provided, whereby prior to beginning the treatment the capacity of the battery is tested to assure that it is sufficient to safely complete the treatment in the event the voltage supply is interrupted.

8. An automated method for preventing early termination of a laser-implemented surgical procedure on corneal tissue due to insufficient power, comprising:
-
determining a minimum amount of power required to perform a complete laser-implemented surgical procedure on a cornea; storing the determination of the minimum amount of power required to perform the surgical procedure; calculating an actual battery capacity based on the tested battery characteristic; generating a control signal representing a comparison of the battery capacity to the stored determination of the amount of power required; automatically preventing a refractive laser system from initiating the surgical procedure on the corneal tissue if the control signal falls below a minimum threshold value. - View Dependent Claims (9, 10, 11, 12, 13)

14. A power supply system for a refractive laser system, comprising:
-
a power supply module for supplying power to a refractive laser system under normal operating conditions; an uninterruptible power supply in electrical communication with the power supply module and the refractive laser system, including; a rechargeable battery for supplying power to the refractive laser system in the event that the power supply module fails, a control module for determining an actual capacity of the rechargeable battery by short-circuiting the rechargeable battery through a test load and generating a control signal representing the actual battery capacity; and wherein if the control signal is less than a minimum predetermined value, the uninterruptible power supply prevents the refractive laser system from operating.
