| 20120137375 | SECURITY SYSTEMS AND METHODS TO REDUCE DATA LEAKS IN ENTERPRISE NETWORKS - Disclosed are embodiments of a security system for reducing data leaks by checking information flows between resources of a network. When an information flow is attempted between a sending resource, which can be anywhere in the network, and a receiving resource residing at a specific host within the network, a host labeler can determine whether information is allowed to flow from the sending resource to the receiving resource.

The conductive electrode is configured so that a Schottky barrier is formed between the second end of at least one of the piezoelectric nanostructures and the conductive electrode when a force is applied to the generator that causes the conductive electrode to touch the piezoelectric nanostructures and to induce stress in the piezoelectric nanostructures. | 12-17-2009 |
| 20090301559 | SOLAR CELL HAVING A HIGH QUALITY REAR SURFACE SPIN-ON DIELECTRIC LAYER - A thin silicon solar cell having a high quality spin-on dielectric layer is described. Specifically, the solar cell may be fabricated from a crystalline silicon wafer having a thickness from 50 to 500 micrometers. A first dielectric layer is applied to the rear surface of the silicon wafer using a spin-on process. A high temperature furnace operation provides simultaneous emitter diffusion and front and rear surface passivation. During this high temperature operation, the front emitter is formed, the rear spin-on dielectric layer is cured, and the front dielectric layer is thermally grown. Barrier layers are formed on the dielectric layers. Openings are made in the barrier layers. Contacts are formed in the openings and on the back surface barrier layer. | 12-10-2009 |
