Title: Non-thermal plasma slit discharge apparatus
Inventor: BABKO-MALYI SERGEI
IPC: F01N3/02
Filed: 2002-11-04
Abstract: A non-thermal atmospheric pressure plasma reactor including a primary dielectric having at least one slit defined therein and a segmented electrod e including a plurality of electrode segments. Each electrode segment disposed proximate and in fluid communication with an associated slit. The slit in th e dielectric may be formed in any number of ways such as a plurality of slits defined in a substantially planar dielectric plate. Other configurations include a plurality of dielectric segments (e.g., bars, slabs, rings, annula r sections) assembled together so that a slit is formed between adjacent dielectric segments. In operation a voltage differential is applied between the segmented electrode and a receiving electrode disposed proximate the primary dielectric to produce a plasma discharge. The plasma discharge is emitted through the slits in the primary dielectric. This inventive plasma discharge device configuration produces a relatively high density non-therma l plasma discharge of relatively large volume yet is relatively easy and inexpensive to manufacture.

Patent CA-2472995-A1 (CA)
Inventor: KRUMM JOHN C
IPC: G08G1/0967
Filed: 2004-07-02
Abstract: The present invention leverages changes in the sensed strength of radio signals at different locations to determine a device's location. In one instance of the invention, inference procedures are used to process ambient commercial radio signals, to estimate a location or a probability distribution over the locations of a device. In an instance of the invention, learning and inference methods are applied to rank vector of signal strength vectors. Moving to such rank orderings leads to methods that bypass consideration of absolute signal strengths in location calculations. The invention facilitates approximations for locating a device by providing a method that does not require a substantial number of available ambient signal strengths while still providing useful location inferences in determining locations.

Title: Improved power supply rejection for high bandwidth transimpedance amplifier circuits (tias)
Inventor: VISOCCHI PASQUALINO MICHELE
IPC: H03F1/30
Filed: 2004-09-03
Abstract: Power supply noise affects the performance of many amplifier circuits. Power supply noise rejection circuits are typically used in conjunction with amplifier circuits to reduce the effects of the noise. Unfortunately, the main issue with a transimpedance amplifier (TIA) is that it has a single input port and a single output port, and the output ports are often required to be of a differential type in order to interface with a differential input post amplifier circuit. As a result, the conversion from single input port operation to a dual input port configuration for differential operation is often the cause of poor power supply noise rejection. A circuit is thus provided that overcomes the limitations in the prior art by providing a differential TIA for use with a filter circuit and differential amplifier that overcomes the limitations of the prior art.
