Abstract: The present invention is directed toward a detection architecture for use in implantable cardiac rhythm devices. The detection architecture of the present invention provides methods and devices for discriminating between arrhythmias. Moreover, by exploiting the enhanced specificity in the origin of the identified arrhythmia, the detection architecture can better discriminate between rhythms appropriate for device therapy and those that are not.

Abstract: Archery bow sights, and archery bows including same are described, the bow sight comprising a sight pin guard having a portion defining a sighting plane, a rotatable shaft having ends installed in the sight pin guard, and at least one sight pin having a connector end and a sight end, the connector end removably and adjustably installed on the rotatable shaft. Certain embodiments comprise a plurality of sight pins arranged on the rotatable shaft at different longitudinal and circumferential locations so that upon rotation of the shaft a different one of the sight pins is viewable in the plane defined by the sight pin guard. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It may not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).

Abstract: Electrical cardiac therapy devices including electrode assemblies having openings for receiving an electrode insertion tool, and methods of inserting such electrode assemblies. The opening(s) are defined on the electrode assemblies to allow an insertion tool to be coupled to the electrode assembly and then used to push the electrode assembly into place.

Abstract: Electrical cardiac therapy devices including electrode lead assemblies having first and second insertion tool receivers. The insertion tool receivers may be attached to an electrode and/or an electrode cover assembly. A lead assembly having first and second insertion tool receivers may be used in conjunction with an insertion tool having means, such as tines, for coupling with the insertion tool receivers. A lead assembly system may include both an insertion tool and a lead assembly. A treatment system further includes an implantable housing along with the lead assembly and insertion tool.

Abstract: Electrical cardiac therapy devices including electrode lead assemblies having appendages coupled to an electrode. The appendage may take the form of a riser and a head having various characteristics. A further embodiment may include a cover and/or other features coupling the electrode to the riser. A lead may be provided for electrical coupling to the electrode. The lead may couple to the electrode exclusive of the riser and head. An implantable housing containing electrical circuitry for using the electrode to stimulate cardiac activity is also illustrated.

Abstract: A unitary subcutaneous implantable cardioverter-defibrillator has a long thin housing in the shape of a patient's rib. The housing contains a source of electrical energy, a capacitor, and operational circuitry that senses the presence of potentially fatal heart rhythms. Provided on the housing are cardioversion/defibrillation electrodes located to deliver electrical cardioversion-defibrillation energy when the operational circuitry senses a potentially fatal heart rhythm. The unitary subcutaneous implantable cardioverter-defibrillator does not have a transvenous, intracardiac, epicardial, or subcutaneous electrode.

Abstract: Semi-submersible floating decanters and methods of use are provided. The decanters are moveable between a non-decant position and a decant position, and include a float forming an internal cavity, the float having a central annulus, a weir having an inlet opening and positioned within the center of the annulus and fixedly connected to the float forming a passage between the float and the weir, and a discharge conduit connected to the weir for discharging a supernatant fluid therefrom. A depth adjusting mechanism is provided for moving the decanter within a liquid between a non-decant position wherein the inlet opening is above the surface of the liquid and a decant position wherein the inlet opening is positioned within the supernatant to allow the supernatant to be withdrawn, the depth adjusting mechanism including a pumping mechanism for moving a fluid relative to the internal cavity.

Abstract: Methods and apparatus for treating wastewater are described, one method embodiment including the steps of flowing a mixed liquor suspended solids to a high rate clarification stage, forming a clarifier effluent, a first waste activated sludge stream, and a return waste activated sludge stream. The high rate clarifier effluent stream then flows to a membrane stage that includes a membrane media, producing a membrane reject (retentate) stream and a treated effluent (permeate) stream. Optionally, the methods include routing a screened raw wastewater to an anaerobic and/or aerated anoxic stage and introducing a gas comprising oxygen to the wastewater during the aerated anoxic stage, and optionally allowing the product of this stage to flow to an aeration stage prior to the high rate clarification stage.
