A computer program product is provided as a network quality control system to perform an automatic validation of all the World Wide Web pages. The quality control system aims at improving the quality of the World Wide Web by promoting widely accepted uniform standards such as HTML, and further by generating web documents that are valid and compliant with the standards according to which they are published. The quality control system actively seeks malformed web pages and corrects them in conformity with their publication standards. The quality control system also automatically determines the most probable addresses of the persons in charge of maintaining the non-conformant web documents using a probabilistic approach, notifies these persons of the non-conformity of their documents, and forwards the corrected web documents to their attention.

An apparatus and method to determine the surface orientation of objects in a field of view is provided by utilizing an array of polarizers and a means for microscanning an image of the objects over the polarizer array. In the preferred embodiment, a sequence of three image frames is captured using a focal plane array of photodetectors. Between frames the image is displaced by a distance equal to a polarizer array element. By combining the signals recorded in the three image frames, the intensity, percent of linear polarization, and angle of the polarization plane can be determined for radiation from each point on the object. The intensity can be used to determine the temperature at a corresponding point on the object. The percent of linear polarization and angle of the polarization plane can be used to determine the surface orientation at a corresponding point on the object. Surface orientation data from different points on the object can be combined to determine the object's shape and pose. Images of the Stokes parameters can be captured and viewed at video frequency. In an alternative embodiment, multi-spectral images can be captured for objects with point source resolution. Potential applications are in robotic vision, machine vision, computer vision, remote sensing, and infrared missile seekers. Other applications are detection and recognition of objects, automatic object recognition, and surveillance. This method of sensing is potentially useful in autonomous navigation and obstacle avoidance systems in automobiles and automated manufacturing and quality control systems.

In a quality control system for manufacturing industrial products, the product quality history and the manufacturing process history are collected and collated to calculate the correlation magnitude between the two histories. The candidates for the cause of quality variation hidden in the manufacturing processes are listed, and the correlation magnitude between all combinations of the variates of the manufacturing process history are calculated. Further, by utilizing the manufacturing sequence history used for an input plan, a causation connecting structure model between the manufacturing processes of the manufacturing line is automatically generated and automatically analyzed thereby to automatically extract the fundamental cause of quality variation from the candidates for the cause of quality variation. By doing so, the cause of quality variation of industrial products manufactured through a complicated process can be traced in a complicated connecting structure in the manufacturing history data.

An energy saving air quality control system modulates supply fan speed by use of controlled, variable-frequency drive controls for automatic dampers or suction pressure to maintain adequate air flow across the evaporator coil at partial cooling loads. Demand ventilation in the system balances air quality and energy consumption by controlling the outdoor air damper in response to indoor CO₂ levels. The control system variously either (1) produces a variable 0-10 VDC output signal to modulate the outside ventilation air damper as required to keep the CO₂ concentration below a set point; (2) produces a 0 or 24 VAC signal to either open or close a two-position outside air damper for as long a time period as is required in order to keep the CO₂ concentration below a set point; or (3) allows manually setting the outside air damper to provide proper ventilation air at maximum occupancy and maximum air flow and modulates the supply fan speed as required to keep the CO2 concentration as measured by a CO2 monitor below set point.

A network quality control system includes a user control console to probe, calculate, and display the quality of an enterprise's network connections to remote SNMP managed devices supporting real-time services like VoIP. Traceroute-like messages are sent to each remote SNMP managed device to report on the path, and hop latency, jitter, and packet losses. MOS scores are computed to indicate performance with a variety of available codec's. Empty test packets used simply to probe network quality are not used. Instead, SNMP messages that carry valuable information or commands for other purposes are gleaned of timing information so the MOS quality scores can be calculated in background.

A quality control system implemented by a service provider for a user via the utilization of sophisticated software algorithms in creating a library of profiles based on product specification. These libraries of profiles are compared with profiles of manufactured products to ensure that manufactured products are within the specification. While the measurement of the manufactured products can be taken in real time, the generation of the profile library is very computationally intensive and requires the use of a highly parallel set of computer workstations for its operation. The system allows for the separation of the computational intensive process from the real-time measurement reading, and creates an opportunity for a service provider to generate and maintain the libraries offsite.

To provide a quality control system of a printed board for realizing efficient quality control.An imaging means picks up images of a printed board in each process in a series of processes for soldering components on the printed board. An image storage means stores (accumulates) the picked-up images in each of processes so that they may be correlated. An inspection means inspects the solder mounting quality from the picked-up image of the final process. Then, if a failure is detected by inspection, a candidate event selecting means selects one or more events which may be a cause of the failure among the events which may be generated in designing steps or an intermediate processes in manufacturing. An event analyzing means determines the degree of occurrence of each of candidate events by referring to the picked-up images in the intermediate processes. A cause analyzing means estimates the cause of the failure on the basis of combinations of the degree of occurrence of each of the candidate events.
