International Classification:

H01L 21302

US Classification:

438710, 438714, 438715, 438718, 438719, 438723, 438724, 438725

Abstract:

A nanomachining method for producing high-aspect ratio precise nanostructures. The method begins by irradiating a wafer with an energetic charged-particle beam. Next, a layer of patterning material is deposited on one side of the wafer and a layer of etch stop or metal plating base is coated on the other side of the wafer. A desired pattern is generated in the patterning material on the top surface of the irradiated wafer using conventional electron-beam lithography techniques. Lastly, the wafer is placed in an appropriate chemical solution that produces a directional etch of the wafer only in the area from which the resist has been removed by the patterning process. The high mechanical strength of the wafer materials compared to the organic resists used in conventional lithography techniques with allows the transfer of the precise patterns into structures with aspect ratios much larger than those previously achievable.

US Classification:

3703952

Abstract:

The improved bandwidth provisioning solution of the present invention enables the provision of bandwidth on demand by dynamically establishing and terminating one or more dynamic virtual circuits (SVCs) () to supplement a subscriber's default broadband connection. The improved bandwidth provisioning solution includes a client-side application () residing on the subscriber's data processing system () and a connection-management application () residing on a proxy signaling server (). The client-side application () transmits a subscriber's request for a bandwidth-on-demand session to the connection-management application (), which communicates with an asynchronous transfer mode (ATM) edge device () using User Network Interface (UNI) signaling to initiate the one or more VCs (). When the subscriber no longer desires the additional bandwidth, the supplemental VCs () may be terminated.

International Classification:

G01C 5/00

US Classification:

2807641, 296 2606, 182 695

Abstract:

A surveillance module may be deployed from a vehicle. The vehicle to deploy the surveillance module includes a first portion configured to accommodate a user to operate the vehicle. A second portion includes a module configured to accommodate the user and comprising a roof and an entrance accessible through an interior of the vehicle from the first portion. The second portion also includes a lifting mechanism coupled to the module and operable to move the module vertically from a retracted position to an extended position. A third portion defines an opening to accommodate the module, wherein the roof of the module couples to a periphery of the opening in the retracted position.
