Abstract: An endpoint detection system for use in detecting an endpoint of a refurbishment process for process chamber components. The refurbishment process involves use of an etchant bath to etch or clean chamber components after their use a reaction chamber in semiconductor processing to remove deposited materials including oxide films or the like. The endpoint detection system is configured to use measurements of reflected electromagnetic radiation from surfaces of the component in an etchant bath, transmitted electromagnetic radiation passing through holes in the chamber component while the component is in the etchant bath, or both to detect process endpoints. The process endpoints can coincide with a desired amount of removal of the deposited materials from surfaces and/or through holes in the chamber component. Upon detection of the endpoints, the chamber component can be removed from the etchant to limit over etching of materials from the chamber component to increase useful life.

Abstract: The water treatment device is an AOP (advanced oxidization process) apparatus that provides effective sanitation of pool water. The device includes couplings that can adapt to fit various standard pool equipment. Inside the reaction chamber of the main body, there are a nozzle and a metal catalyst. The nozzle creates water jet impinging the metal catalyst, which subsequently creates bubbles. Being entrained in the water, the bubbles substantially collapse and create high temperature and pressure changes. These changes cause water to go through chemical dissociation, thus creating hydroxyl radicals, a highly reactive oxidizer. In a fast rate, the hydroxyls attach to and destroy organic contaminants in the water. The metal catalyst remains chemically unchanged. The apparatus has a long service life and substantially reduces the use of chemicals in a pool.

Abstract: A modular biofiltration support system for a bed of organic filter medium, formed of a multiplicity of rectangular bed platform modules or floor tiles, provides for bridging across an air/gas supply trench which can be up to 36 inches or even 48 inches wide. The bridging sections, formed of a mix of recycled plastic materials in a high-pressure molding operation, interconnect with edges of the floor tile assemblies on each side of the trench, and also engage with one another at sides. Each module is a high strength beam.

Abstract: An ice fishing tool takes the form of an articulating scoop or ladle for scooping out fish, ice, or debris configured as an ice fishing tool. The tool comprises a handle, a perforated scoop, and a shaft connecting the handle to the scoop. The tool also comprises an articulating actuating assembly made up of a spring and one or more pivotally-connected links that couple a handle trigger to the scoop. Actions of squeezing the handle trigger toward the handle and releasing the handle trigger cause the scoop to move between a position approximately parallel to the shaft and a position approximately perpendicular to the shaft.

Abstract: An oil lamp-type apparatus or a Kukui pot candle device for achieving the illumination and the appearance of an ignited oil lamp. This is achieved by illuminating water flowing upward (e.g., substantially vertically to provide a flame-shaped element or small fountain of water above the pool surface) using a light source directing its light output upward through the water. The flame-shaped element has kinetic and dynamic movement similar to a flame on an oil lamp or candle wick due to the combination of the water flowing upward and the water falling nearly straight down back into a pool about the water outlet. Further, the effect is achieve by only illuminating the liquid in the flame-shaped element with the vertically upward-direct light stream and not by shining light from the side, from above, or even from an adjacent location.

Abstract: Aspects of the present invention provide novel methods and devices for sampling gas, exciting the sampled gas to emit radiation and detecting in real time from the emitted radiation a plurality of wave bands of an emission spectrum. Energy used to excite the sampled gas may be adjusted based on the detected wave bands. A process may be controlled in real time based on the detected wave bands. Novel interfaces may be used to display portions of the detected wave bands. A known flow of a reference gas may be included in the flow of sampled gases and an unknown flow of an unknown flow gas determined.

Abstract: The present invention relates to monitoring chemicals in a process chamber using a spectrometer having a plasma generator, based on patterns over time of chemical consumption. The relevant patterns may include a change in consumption, reaching a consumption plateau, absence of consumption, or presence of consumption. In some embodiments, advancing to a next step in forming structures on the workpiece depends on the pattern of consumption meeting a process criteria. In other embodiments, a processing time standard is established, based on analysis of the relevant patterns. Yet other embodiments relate to controlling work on a workpiece, based on analysis of the relevant patterns. The invention may be either a process or a device including logic and resources to carry out a process.

Abstract: A set of interconnected delay stages, such as a voltage-controlled oscillator, has switch-controlled load circuitry connected to each output of each delay stage in the oscillator ring. In one embodiment, for each delay stage output, the switch-controlled load circuitry includes a switch, a transistor, and a current source. The switch is connected between the corresponding delay stage output and the transistor gate, the current source is connected between a power supply and the transistor drain, and the transistor source is connected to ground. In such a configuration, the transistor's gate-to-source capacitance can be applied to the corresponding delay stage output by closing the switch, for example, for lower-frequency operations. In addition, the output impedance of the current source decouples the capacitive load from the power supply, thereby substantially shielding the oscillator ring from noise in the power supply.
