Apparatus and methods for treatment of stroke are provided. In a preferred embodiment, the present invention disposes at least one catheter having a distal occlusive member in either the common carotid artery (CCA) or both the vertebral artery (VA) and the CCA on the hemisphere of the cerebral occlusion. Blood flow in the opposing carotid and/or vertebral arteries may be inhibited. Retrograde or antegrade flow may be provided through either catheter independently to effectively control cerebral flow characteristics.

The present invention provides a process for separating a good quality information signal from a noisy acoustic environment. The separation process uses a set of a least two spaced-apart transducers to capture noise and information components. The transducer signals, which have both a noise and information component, are received into a separation process. The separation process generates one channel that is substantially only noise, and another channel that is a combination of noise and information. An identification process is used to identify which channel has the information component. The noise signal is then used to set process characteristics that are applied to the combination signal to efficiently reduce or eliminate the noise component. In this way, the noise is effectively removed from the combination signal to generate a good qualify information signal. The information signal may be, for example, a speech signal, a seismic signal, a sonar signal, or other acoustic signal.

A method of efficiently removing backfacing primitives from the graphics pipeline such that rendering efficiency is increased. In one embodiment of the present invention, a bounding cone of normal vectors of a primitive is first determined during pre-processing.

In another embodiment, a normal bit-vector is used to represent normal directions of a primitive, and a visibility bit-vector is used to represent visible normal directions. In that embodiment, primitives are culled efficiently by comparing the normal bit-vector with the visibility bit-vector.

A post-incubation treatment is employed to effectively remove targets, such as proteins/protein complexes, or other label-bearing moieties that may non-specifically bind to a microarray substrate during a binding assay. Following incubation, a one-step wash is carried out with a liquid containing digester, e.g., a digestive enzyme (protease) or lysosome, which is effective to remove non-specifically bound targets or at least labeled portions of such targets from the substrate. Proteases are bound to or coated onto large molecules or onto solid particles of such a size such that they are prohibited from entering the porous surfaces of 3-D hydrogel microspots and are unable to reach and digest labeled target-probe complexes that are disposed within such porous hydrogel microspots. Digested segments of such protein which contain labels (or of essentially the entire protein) are carried away in the wash liquid and thus are not present to create background noise during imaging.
