  • Patent number: 8384042
    Abstract: When using micro-resonant structures, a resonant structure may be turned on or off (e.g., when a display element is turned on or off in response to a changing image or when a communications switch is turned on or off to send data different data bits). Rather than turning the charged particle beam on and off, the beam may be moved to a position that does not excite the resonant structure, thereby turning off the resonant structure without having to turn off the charged particle beam. In one such embodiment, at least one deflector is placed between a source of charged particles and the resonant structure(s) to be excited. When the resonant structure is to be turned on (i.e., excited), the at least one deflector allows the beam to pass by undeflected. When the resonant structure is to be turned off, the at least one deflector deflects the beam away from the resonant structure by an amount sufficient to prevent the resonant structure from becoming excited.

  • Publication number: 20120065802
    Abstract: Systems and methods for managing and monitoring a plurality of disparate electrical and/or electronic devices located at various geographically distributed facilities remotely on the basis of an instantaneous location of a user's mobile device that is associated with one or more electrical and/or electronic devices. Remote management of these devices involve transmitting information corresponding to a current location of a user's mobile device that will be managing the devices, without the need for installing additional software on the devices. An energy management system installed within an organization's infrastructure communicates with users' mobile devices and executes power management commands on the electrical and/or electronic devices, for purposes of monitoring and managing several operational aspects related to such devices. Such power management commands can be on-demand dynamic commands provided by a user's mobile device, or predefined commands stored in the energy management system.

  • Patent number: 7990336
    Abstract: An electronic receiver array for detecting microwave signals. Ultra-small resonant devices resonate at a frequency higher than the microwave frequency (for example, the optical frequencies) when the microwave energy is incident to the receiver. A microwave antenna couples the microwave energy and excites the ultra-small resonant structures to produce Plasmon activity on the surfaces of the resonant structures. The Plasmon activity produces detectable electromagnetic radiation at the resonant frequency.

  • Patent number: 7986113
    Abstract: We describe an ultra-small resonant structure that produces electromagnetic radiation (e.g., visible light) at selected frequencies that can also be used or formed in conjunction with passive optical structures. The resonant structure can be produced from any conducting material (e.g., metal such as silver or gold). The passive optical structures can be formed from glass, polymer, dielectrics, or any other material sufficiently transparent using conventional patterning, etching and deposition techniques. The passive optical structures can be formed directly on the ultra-small resonant structures, or alternatively on an intermediate structure, or the passive optical structures can be formed in combination with other passive optical structures.

  • Patent number: 7911145
    Abstract: An electronic transmitter or receiver employing electromagnetic radiation as a coded signal carrier is described. In the transmitter, the electromagnetic radiation is emitted from ultra-small resonant structures when an electron beam passes proximate the structures. In the receiver, the electron beam passes near ultra-small resonant structures and is altered in path or velocity by the effect of the electromagnetic radiation on structures. The electron beam is accelerated within a series of spiral-shaped anodes to an appropriate current density without the use of a high power supply. Instead, a sequence of low power levels is supplied to the sequence of anodes in the electron beam path. The electron beam is thereby accelerated to a desired current density appropriate for the transmitter or receiver application without the need for a high-level power source.

    Abstract: Methods, program products, and systems for managing database access privileges using administration groups are described. Administrative functions for managing a database server and administrative functions for managing collections of databases can be separated. Groups of databases can be created on the database server. Tasks for adding and managing multiple databases can be delegated from a server administrator to one or more group administrators who can manage one or more groups of databases. The groups of databases can be stored in various home folders, each home folder corresponding to a group. Management rights on the databases can be determined by the home folders in which the databases are located.
