An illumination system comprises (a) a first optical element upon which a light beam impinges, where the first optical element has first raster elements that partition said light beam into light channels; (b) a second optical element that receives said light channels, where the second optical element has a second raster elements; (c) an object plane that receives said light channels via said second optical element; and (d) an exit pupil that is provided with an illumination via said object plane. The system is characterized by an assignment of a member of said first raster elements and a member of said second raster elements to each of said light channels to provide a continuous beam path from said first optical element to said object plane for each of said plurality of light channels. The assignment is changeable to provide an adjustment of said illumination in said exit pupil.

A system for treating a target region in tissue beneath a tissue surface comprises a probe for deploying an electrode array within the tissue and a surface electrode for engaging the tissue surface above the treatment site. Preferably, surface electrode includes a plurality of tissue-penetrating elements which advance into the tissue, and the surface electrode is removably attachable to the probe. The tissue may be treated in a monopolar fashion where the electrode array and surface electrode are attached to a common pole on an electrode surgical power supply and powered simultaneously or successively, or in a bipolar fashion where the electrode array and surface electrode are attached to opposite poles of the power supply. The systems are particularly useful for treating tumors and other tissue treatment regions which lie near the surface.

The present invention relates to a multi-input multi-output (MIMO) antenna with a multi-band characteristic which includes a plurality of MIMO antenna, each having a pair of antenna elements, to support multiple bands, and is capable of guaranteeing high antenna efficiency for different bands by minimizing an interference between antenna elements of each MIMO antenna to improve an isolation characteristic. The MIMO antenna system having a multi-band characteristic, which includes two pairs of antenna patterns to support different band and coupling antenna parts separated from and coupled with the pairs of antenna patterns, can improve an isolation through the coupling antenna parts and guarantee an antenna gain. Moreover, since signal interference caused by the coupling effect can be cancelled to guarantee a band width with no change in antenna characteristics, it is possible to constructing two or more antennas to support a multi-band while guaranteeing stable operation of the antennas.

Virtualization platforms and management clients therefor are communicatively coupled to one another via a control layer logically disposed therebetween.

This invention is concerned with a new method for producing cross-linked hyaluronic acid—protein bio-composites in various shapes. In the present process, a polysaccharide solution and a protein solution are mixed under moderate pH values in presence of salts to form a homogenous solution, which can be processed into various shapes, such as membrane, sponge, fiber, tube or micro-granular and so on. After then, the homogenous solution is subjected to a cross-linking reaction in organic solvent containing weak acid to produce an implantable bio composite material having excellent bio-compatibility, biodegradability, prolonged enzymatic degradation time, and good physical properties.

Protected anode architectures have ionically conductive protective membrane architectures that, in conjunction with compliant seal structures and anode backplanes, effectively enclose an active metal anode inside the interior of an anode compartment. This enclosure prevents the active metal from deleterious reaction with the environment external to the anode compartment, which may include aqueous, ambient moisture, and / or other materials corrosive to the active metal. The compliant seal structures are substantially impervious to anolytes, catholyes, dissolved species in electrolytes, and moisture and compliant to changes in anode volume such that physical continuity between the anode protective architecture and backplane are maintained. The protected anode architectures can be used in arrays of protected anode architectures and battery cells of various configurations incorporating the protected anode architectures or arrays.
