Title: Soil-resistant coating for glass surfaces
Inventor: STANEK ROGER
IPC: C23C14/00
Filed: 1999-02-02
Granted: 2006-05-23
Abstract: A glass article which has a water-sheeting coating and a method of applying coating to opposed sides of a substrate are described. In one embodiment, a water-sheeting coating (20) comprising silica is sputtered directly onto an exterior surface of the glass. The exterior face of this water-sheeting coating is substantially non-porous but has an irregular surface.  This water-sheeting coating causes water applied to the coated surface to sheet, making the glass article easier to clean and helping the glass stay clean longer. In one method of the invention, interior and exterior surfaces of a glass sheet are cleaned. Thereafter, the interior surface of the sheet of glass is coated with a reflective coating by sputtering, in sequence, at least one dielectric layer, at least one metal layer, and at least one dielectric layer.  The exterior surface of the glass is coated with a water-sheeting coating by sputtering silica directly onto the exterior surface of the sheet of glass. If so desired, both the interior surface and the exterior surface can be applied during the same pass through the same sputter coating apparatus while the glass maintains a constant orientation wherein the interior surface is positioned above the exterior surface.

Title: Method and system for testing subscriber loops using touchtone telephone signals
Inventor: ERVING RICHARD HENRY
IPC: H04Q1/45
Filed: 2002-06-04
Granted: 2005-06-28
Abstract: A subscriber loop test apparatus relates to the testing of a subscriber loop by the use of a touchtone telephone. The touchstone buttons on a telephone provide Dual-Tone, Multiple Frequencies for each key pressed. For example, referring to Figure 1, pressing the '3' key causes tones at 697 and 1477 Hz to be sent across the telephone line. Pressing a sequence of keys provides discrete coverage of the frequency band from 697 to 1477 Hz, through the use of the touchtone telephone. The frequency band from 697 to 1477 Hz can be characterized in this fashion. Information about the line: loop loss (loop length), presence of bridge taps (i.e., excessively long bridge taps in particular) or loading coils, and the presence of Digital Loop Carriers (DLCs), et cetera. The use of the switch-hook flash provides the ability to determine the channel (impulse) response of the loop, including any noise and hum that may be on the loop due to imbalance or coupled interference.

IPC: H04L12/24
Filed: 2004-05-11
Granted: 2011-06-28
Abstract: The accuracy of configuration data within routers of a network are critical in today's networks for security of the network, efficient operating of the network and to ensure corporate requirements, such as redundancy, are met. Since configuration data is typically entered and modified manually by technicians, considerable human errors occur. A configuration validation system provides an automated capability to ensure accuracy within the routers of a network. In this system, the validation is completed utilizing dynamically set conditions based upon the utilization of the router and a characteristic of the muter, such as the model type. The utilization of the router includes the services that are supported by the router and the position of the router within the network, both of these criteria of the router having specific configuration requirements. The utilization of the routers can be detected by look-up within an inventory database and/or analysing the applicable configuration data. During the validation process, any discrepancies can be logged. At completion, these discrepancies can be listed within a report of configuration problems to be fixed or be automatically sent to the routers within the network to correct the configuration data.
