Bi-directional balance low noise communication interface

The present invention relates to RJ45 modular inserts that are connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to reduce near-end cross-talk (“NEXT”) without compromising impedance. NEXT is substantially reduced by utilizing a low reactance dielectric insert with a two-stage combination positive and negative compensation removal technique. By utilizing this method, the pair-to-pair NEXT is substantially reduced and differential pair impedance are controlled in a simple and cost effective manner.

Photoionization enabled electrochemical material removal techniques for use in biomedical fields

A method for controlled removal of surface tissue layer portions with a non-contact energy delivery modality that applies electrical energy to the targeted tissue surface to cause electrochemical ablation. The system provides (i) a UV energy source for irradiating a beam path through a selected neutral gas environment overlying the targeted tissue thereby creating an ionized gas volume (i.e., a conductive non-equilibrium plasma), and (ii) an electrical source for creating an intense electrical field in the ionized gas volume to thereby apply energy to the targeted surface layer to cause volatilization and removal of the surface layer in a plasma-mediated ablation. The ultrafast plasma creation events are repeated at a high repetition rate to ablate surface layer portions in a controlled manner. Each ultrafast plasma creation event is of such a high intensity and such a brief duration that thermal energy is not transferred to the tissue thus preventing collateral thermal damage to regions adjacent to the targeted site.

Application sharing with occlusion removal

Techniques are disclosed for window sharing with occlusion removal. In an embodiment, the techniques begin with a blank composition image, to which shared windows are added. For each window of a desktop from which at least one window is shared, traversing the windows from greatest z-depth to least z-depth, the window is processed based on whether it is shared and is occluded. Shared windows are copied to the composition image. Where a part of a shared window is occluded and cannot be retrieved, an indication of this occlusion is added to the composition image. When the windows have been processed, the composition image is encoded and sent to a client computer where it is displayed to produce the window sharing between computers.

Treatment of Flue Gas From an Oxyfuel Combustion Process

Carbon monoxide (CO) may be removed from flue gas generated by oxyfuel combustion of a hydrocarbon or carbonaceous fuel, by contacting the flue gas, or a CO-containing gas derived therefrom, at a first elevated temperature, e.g. at least 80° C., and at a first elevated pressure, e.g. at least 2 bar (0.2 MPa), with at least one catalyst bed comprising a CO-oxidation catalyst in the presence of oxygen (O2) to convert CO to carbon dioxide and produce carbon dioxide-enriched gas. The carbon dioxide produced from the CO may be recovered from the carbon dioxide-enriched gas using conventional carbon dioxide recovery techniques. NO in the flue gas may also be oxidized to nitrogen dioxide (NO2) and removed using conventional NO2 removal techniques, or may be reduced in the presence of a reducing gas to nitrogen (N2) which does not have to be removed from the gas.

Ghost image correction system and method

A new and useful method and system for correcting for ghost images in a telecentric optical system is provided. Ghost images generated from planar optical surfaces in the image space after the major elements of a telecentric optical system are shift invariant. In other words the ghost images produced by these optical elements do not change their shape with different field angles or points. The ghost image's invariance with field position will allow the ghost image to be subtracted or removed from the image of an object recorded on a digital detector such as CCD or CMOS detector when its optical system is telecentric in image space. This subtraction may be accomplished, for example, with a removal technique using a measured ghost function germane and invariant to that particular optical system. The combination of the ghost image and scatter functions is linearly shift invariant and therefore, both noise contributions could be removed from the resulting digital image using similar removal techniques.

Method, apparatus, and kit for thermal suture cutting

A novel suture removal instrument, kit and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and / or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.
