20120281083 | Thermal Imager with Hermetically Sealed and Pressurized Housing - The present invention relates to an imaging device with a thermal imaging surveillance capability for safety, security and situational awareness. Closed circuit television systems (CCTV) are usually supported on drive and actuating mechanisms so that their active imaging portions are housed in a protective environment in a transparent dome. Existing thermal imaging devices are used in fixed configurations or on platforms and are bulky and expensive. In addition they are unsuitable for harsh marine environments. The invention is an imaging device and comprises: a thermal imager, which in use is housed within a sealed housing. A pan and tilt mechanism is supported in the housing for displacing the thermal imager. A dome, formed from an infra-red (IR) transmitting material, covers and seals the housing (which is ideally filled with an inert gas) thereby resulting in an arrangement that is resistant to exposure to water and salt and so provides an imager suitable for marine environments, as well resulting in an overall reduction in size of the imager compared with exposed pan and tilt mechanisms. | 11-08-2012 |

20100192773 | ABATEMENT APPARATUS WITH SCRUBBER CONDUIT - Embodiments of an abatement apparatus are disclosed herein. In some embodiments, an abatement apparatus may include a scrubber configured to receive an effluent stream from a process chamber and further configured to remove first particles from the effluent stream; a scrubber conduit coupled to the scrubber to receive the effluent stream therefrom and configured to remove second particles from the effluent stream, the scrubber conduit having one or more inlets configured to provide a fluid to sufficiently wet an interior surface of the scrubber conduit to trap the second particles thereon and to wash the second particles therealong; and a central scrubber coupled to the scrubber via the scrubber conduit. In some embodiments, the scrubber conduit is downward sloping from the scrubber to the central scrubber. In some embodiments, a plurality of scrubbers may be coupled to the central scrubber via a plurality of scrubber conduits. | 08-05-2010 |
20110070811 | POINT OF USE RECYCLING SYSTEM FOR CMP SLURRY - The present invention generally relates to apparatus and method for recycling both polishing slurry and rinse water from CMP processes. The present invention also relates to rheology measurements and agglomeration prevention using centrifugal pumps. | 03-24-2011 |
20120091099 | METHODS AND APPARATUS FOR RECOVERY AND REUSE OF REAGENTS - Methods and apparatus for recovery and reuse of reagents are provided herein. In some embodiments, a system for processing substrates may include a process chamber for processing a substrate; a reagent source coupled to the process chamber to provide a reagent to the process chamber; and a reagent recovery system to collect, and at least one of purify or concentrate the reagent recovered from an effluent exhausted from the process chamber. In some embodiments, a method for recovering unreacted reagent may include providing reagent from a reagent source to a process chamber; exposing a substrate disposed in the process chamber to the reagent, forming an effluent; exhausting the effluent from the process chamber; and recovering unreacted reagent from the effluent in a reagent recovery system. | 04-19-2012 |

20100309037 | SAMPLING COMPARATORS - An improved regenerative clocked sampling circuit is described which uses a single clocking signal to switch the circuit between a tracking phase in which the state tracks the input signal, and a bistable phase during which the state rapidly approaches one of two states dependant on the input signal. The same clock signal also isolates the bistable circuit from the input signal source. In a preferred embodiment, these two actions are performed by the same transmission gate or gates connecting the input to the potentially bistable circuit. | 12-09-2010 |

20090295494 | WAVEGUIDE CONNECTOR - A compact end launch transition for providing a connection between a housing having an electrical terminator and a waveguide component and associated method are described. The transition includes a having a rear side presenting a substantially flat surface to abut the housing and has a front side having an aperture. An antenna located within the body is configured to interact with the aperture to form an end launch transition. An electrical connector is in electrical communication with the antenna and exposed from the rear side of the body to connect directly to the electrical terminator. This avoids the need to use cable to connect the housing and waveguide component and provides a particularly compact device. | 12-03-2009 |
