A dimensioning system can include stored data indicative of coordinate locations of each reference element in a reference image containing a pseudorandom pattern of elements. Data indicative of the coordinates of elements appearing in an acquired image of a three-dimensional space including an object can be compared to the stored data indicative of coordinate locations of each reference element. After the elements in the acquired image corresponding to the reference elements in the reference image are identified, a spatial correlation between the acquired image and the reference image can be determined. Such a numerical comparison of coordinate data reduces the computing resource requirements of graphical comparison technologies.

The present invention comprises a multi-tier system. Major goals of the system are to 1) clearly visualize BGP dynamics and alert / report important deviation of BGP dynamics to avoid overwhelming the operators with too much information and 2) analyze the root cause of the problems by using a multi-tier approach, with a light-computational analysis and high-level classification for a real-time problem identification followed by a more rigorous off-line analysis for a further and more detailed trouble shooting. An example embodiment is provided that comprises four modules. The first module comprises a distributed family of collectors in charge of collecting real-time network information. The second module filters out non-relevant prefixes and extracts and profiles key features of the network information. The third module monitors BGP activity from both an Internet-AS and single-AS perspectives by displaying the data in real time and highlighting major shifts or divergence from historical baselines with comprehensive layouts. The forth module is run off-line to focus on a few relevant events that are selected through the first three modules. This is usually a time-consuming phase of the process due to the different temporal and / or spatial correlation that must be run across several sets of data. During this phase, the system can spend more time to better identify the real cause of the problem.

The present invention provides solutions to simplify and reduce the resources needed for manufacturing liquid crystal display modules. Failure of mid-process steps during mass production can result in significant costs. According to certain embodiments of the present invention, a WOA display panel architecture requires fewer LCM resources or has no PCB. Although the COG process and WOA method provide higher reliability in temporary LCD production, the costs associated with the space required for wires on the PCB or display panel for larger panel sizes remains expensive. Larger panel sizes also requires an increased number of driver ICs to construct a flat display panel. Similarly, the number of wires connecting each driver IC to a timing controller IC, gamma operational amplifier IC and DC-to-DC converter IC creates spacing problems that translate into higher production costs. These problems can be solved by certain embodiments of the present invention.
