  • Patent number: 8881021
    Abstract: A toolbar, such as an add-on toolbar for a web browser, may be automatically created for a user based on the preferences or habits of the user. A device may, for example, receive metadata relating to habits or preferences of the user. The device may match the metadata to a set of toolbar objects to obtain one or more recommended toolbar objects for the user. The device may generate custom toolbar code that includes the one or more recommended toolbar objects and transmit the custom toolbar code to the user for installation of the custom toolbar code to implement a custom toolbar in the application program.

  • Patent number: 5173761
    Abstract: A method and apparatus for contructing diamond semiconductor structures made of polycrystalline diamond thin films is disclosed. The use of a polycrystalline diamond deposition on a substrate material provides an advantage that any substrate material may be used and the ability to use polycrystalline diamond as a material is brought about through the use of an undoped diamond layer acting as an insulating layer which is formed on a boron-doped layer. Because of the structure, ion implantation can be employed to reduce the ohmic contact resistance. The ion implantation also provides that the entire structure can be made using a deep implant to form a channel layer which allows the insulating gate structure to be formed as an integral part of the device. The buried channel can be doped through the use of several implantation steps through the insulating undoped layer.
