  • Patent number: 7418179
    Abstract: A device including an input port configured to receive an input signal is described. The device also includes an output port and a structure, which structure includes a tunneling junction connected with the input port and the output port. The tunneling junction is configured in a way (i) which provides electrons in a particular energy state within the structure, (ii) which produces surface plasmons in response to the input signal, (iii) which causes the structure to act as a waveguide for directing at least a portion of the surface plasmons along a predetermined path toward the output port such that the surface plasmons so directed interact with the electrons in a particular way, and (iv) which produces at the output port an output signal resulting from the particular interaction between the electrons and the surface plasmons.

  • Patent number: 7388276
    Abstract: A varactor is configured with first and second conducting layers, spaced apart from one another such that a given voltage can be applied across the first and second conducting layers. Further, an insulator arrangement includes at least one insulator layer disposed between the first and second conducting layers, configured to cooperate with the first and second conducting layers to produce a charge pool which changes responsive to changes in the given voltage such that a device capacitance value between the first and second conducting layers changes responsive to the given voltage. The insulator arrangement can include one layer, two distinct layers or more than two distinct layers. One or more of the layers can be an amorphous material. A zero-bias voltage version of the varactor is also described.

  • Patent number: 4053938
    Abstract: A temperature sensing transformer primary switch for a distribution transformer, the switch being mounted within the distribution transformer below the level of the dielectric fluid and being manually operable externally of the transformer for opening the primary circuit and deenergizing the transformer, the switch including a temperature sensing device mounted on the internal end of the transformer below the level of the dielectric fluid to open the primary switch in response to overload temperatures produced on the transformer's secondary circuit. The temperature sensing device includes a compression spring and a wax motor for releasing the energy stored in the compression spring as the temperature of the dielectric fluid reaches a predetermined maximum temperature. The spring is preloaded sufficiently by a manual operation to actuate the switch at the maximum temperature. A pressure responsive switch assembly is provided for opening the primary switch.
