A real-time hotspot detection system is disclosed. In a preferred embodiment, the real-time hotspot detection system of the present invention comprises a photolithography stepper that has been modified to output z-height focus data for each cell to a fault detection module of the present invention. After the entire wafer has been exposed by the stepper, the fault detection module computes the mean and standard deviation and/or other statistical data for the wafer data and compares the computed standard deviation with a predetermined limits for “normal” standard deviation, representative of a completely flat wafer having no hotspots thereon. If the computed standard deviation is outside the limits for the normal standard deviation, the fault detection module provides control signals to the stepper for halting the operation thereof and for generating an indication to the stepper operator, via a pole light associated with the stepper, that a failure has occurred. In addition, a wafer map showing the z-height data of the wafer that caused the failure may be displayed on a display associated with the module to enable a visual inspection to be performed and the cause of the hotspot to be more easily located.

Cell frame for high-pressure water electrolyzer and method of manufacturing the same. According to one embodiment, radial openings in a water electrolyzer frame are provided by laminating half-frames, one or both of which contains grooves that may be formed by molding, machining or die-cutting. Another to another embodiment, radial openings are provided by laminating three or more thin frame portions, the center piece of which may include transverse slots that may be made by molding, machining or die-cutting. According to yet another embodiment, two or more frame portions are provided, at least one of which includes a recess for receiving a porous structure. The frames of the present invention can be additionally laminated to the membrane and electrode assembly, as well as the bipolar separator plate in the perimeter or seal area, comprised of the same or similar material as the frame, to form unitized electrolyzer stack subassemblies or full assemblies.

A bundle handling device is provided that includes a frame, a body, a scoop, a ramp and a controller. The body is mounted to the frame and includes a first opening through which bundles are loaded and a second opening through which bundles are discharged. The scoop and the ramp are mounted to the body. The scoop covers a substantial portion of the second opening, while the ramp covers the remaining portion. The controller is coupled to a plurality of actuators and a plurality of sensors, and controls the rotation of the body, the opening and closing of the scoop and the opening and closing of the ramp, in order to discharge a metered portion of bundles through the second opening.

A spring perch assembly for automatically centering a load applied to a spring is provided. The assembly includes a body portion and a base portion which when engaged may tilt relative to one another. When disposed between a spring and an applied load, the assembly automatically centers the load along the spring's natural centerline.

The present invention is a system and method for the automatic control of a debarking system for use in a chip mill, paper mill, or the like. The present invention comprises one or more programmable logic controllers (PLCs) that receive input from ultrasonic sensors that measure the quantity of wood present at various locations within the system. Based on this data, the PLCs reference look-up tables that contain information on start, stop, speed up, and slow down times for various system components based on such criteria as wood variety and season. The control system optimizes the fiber yield from the debarking system while also reducing mechanical wear on components of the system by reducing the time at which components are run at high speed.

A mounting head, a system incorporating the mounting head and a support such as a monopod, and a system including the mounting head, the monopod, and a camera enable a photographer to tilt a monopod or other camera support while maintaining a substantially level horizon of an image. An upper head assembly and a lower head assembly are connectable to the camera and the monopod respectively. The assemblies are interconnected by a universal joint which allows the upper assembly to remain level as roll and pitch vary. A resilient member dampens relative motion of the head assemblies. As a photographer moves the camera to capture a scene, force is transmitted from the photographer's hands via the mounting head through the monopod. The photographer maintains a level horizon as the monopod tilts. A test apparatus enables design of a resilient member for desired interaction with selected classes of equipment.

An improved method and apparatus for client-side web application analysis is provided. Client-side web application analysis involves determining and testing, using client-side application interfaces and the like, data input points and analyzing client requests and server responses. In one embodiment, a security vulnerability analyzer is employed to analyze web page content for client-side application files, such as Flash files and Java applets, extract web addresses and data parameters embedded in the client-side application file, and modify the data parameters according to user-defined test criteria. The modified data parameters are transmitted as part of a request to a respective web server used to service the client-side application files. The security vulnerability analyzer analyzes the response from the server to ascertain if there are any security vulnerabilities associated with the interface between the client-side application file and the web server.

There is disclosed herein an apparatus and a method in which a workpiece is loaded into the apparatus and the apparatus then moves and positions the workpiece in a multitude of directions based upon the directions and controls supplied to the apparatus through either a computer and applets, a programmable controller and/or through manual intervention. The apparatus can move the workpiece linearly to a predetermined position, rotate the workpiece in a continuous motion, index the workpiece incrementally and/or do any combination of those movements. The apparatus can also control other components such as turning coolant and/or quench valves on and off as desired or powering working tools such as an induction hardening coil. The workpiece is loaded directly on the center of the apparatus movement and positioning device for increased capacity loading and precision movement.
