O2Micro Int. Ltd was granted 19 claims under GB (Great Britain) patent number 2,398,403 for its power switch device for PC cards.

The invention brings new circuitry to a PC card power switch to automatically sense specialty card applications, such as USB PC Cards. The enhanced PC card power switch may automatically switch in external resources and power the socket based on sensing inputs. It is particularly useful for enabling ExpressCard compatible PCI-Express and USB2.0 interfaces, offering a PC Card adapter for the new connectivity scheme.

"With this invention, O2Micro reduces the complexity of adding new connectivity interfaces to a PC card socket, enabling technologies such as USB2.0 without modifying the digital controller," commented Max Huang, O2Micro's EVP of the Intelligent E-commerce business unit.
