摘要： System and method for driving one or more cold-cathode fluorescent lamps. For example, the method includes generating at least one drive signal associated with a signal frequency, the signal frequency being equal to a first predetermined frequency, receiving a current-sensing signal, the current-sensing signal being associated with a lamp current for the one or more cold-cathode fluorescent lamps in response to at least the first predetermined frequency, and determining whether the current-sensing signal is larger than a first threshold in magnitude, the current-sensing signal being related to the first predetermined frequency. Additionally, the method includes, if the current-sensing signal related to the first predetermined frequency is determined to be larger than the first threshold in magnitude at anytime during a first period of time, changing the signal frequency from the first predetermined frequency to a second predetermined frequency, the second predetermined frequency being different from the first predetermined frequency.

摘要： Methods and systems for forming vacuum insulated containers, such as beverage and food containers, are described. The methods and systems include using a laser to close openings in walls of the container while the container is held at vacuum conditions. The closing of the opening forms the vacuum space within the walls of the container.
