| 20090013098 | METHOD AND APPARATUS FOR PROVIDING UNIVERSAL WEB ACCESS FUNCTIONALITY - A flexible electronic asset management system using Ethernet connectivity for electronic devices is presented. The invention enables multiple electronic devices to be controlled, monitored, and accessed from any browser connected to a computer network. A flattened stack approach is used to process network packet data. The flattened stack approach treats the network packet as a single string of data and uses the first few bytes of information to decide whether to drop or process the incoming data thus providing for faster network traffic processing. Since the lowest layer of the OSI stack has knowledge of what applications are active in the upper layers, the flattened stack allows the packet to be discarded at the earliest possible point so no processing power is wasted. The flattened stack also organizes its check/processing based on the raw data stream thus minimizing buffer requirements and providing for easier implementation into hardware. | 01-08-2009 |
| 20080314614 | MIRRORED ARC CONDUCTING PAIR - A mirrored arc geometrical arrangement of two conductors configured to perform similar functions as a traditional twisted pair of wires is presented. The mirrored arc conductor pair occupies the same physical space required by prior art twisted pair cable designs. Each conductor pair includes two inward-facing arc shaped conductors placed within a dielectric material. Each arc shaped conductor may be constructed from thin foil strips of a conducting metal or from a group of separate bare metal conductors which are placed side by side in intimate contact so as to effectively create the same mirrored arc geometry. The conductor pairs may subsequently be bundled to create a data network cable bundle. | 12-25-2008 |
