Patents by Inventor Gil MacDonald

Gil MacDonald has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dual input AC/DC power converter having a programmable peripheral power hub module
    Patent number: 6791853
    Abstract: A peripheral power hub (PPH) (44) providing power to a plurality of outputs (46). The PPH provides multiple predetermined DC voltages which may be converted by an associated voltage converter circuit (28) to provide the power requirements to an associated mobile device (72). Alternatively, the voltage converter circuits (28) may be internal to the PPH. A programmable Ac/Dc converter (42) may provide a DC voltage to the PPH, which may be configured as an an accessory while powering another mobile device, such as a laptop computer (50). The voltage converter circuits (28) may be buck circuits or boost circuits depending on the application.
