Patent number: 10090564Abstract: An electrochemical cell includes a negative electrode comprising a first active metal, a positive electrode comprising a second active metal, and an electrolyte comprising salts of the two active metals, a salt of the cathodic metal and a salt of the anodic metal. In operation, the electrolyte composition varies such that in a charging mode the salt of the anodic salt decreases, while the salt of the cathodic salt increases, and in a discharging mode the salt of the anodic salt increases, while the salt of the cathodic salt decreases. The cell is operational for both storing electrical energy and as a source of electrical energy as part of an uninterruptible power system.

Patent number: 8963262Abstract: The disclosure is generally directed to fabrication steps, and operation principles for microelectromechanical (MEMS) transducers. In one embodiment, the disclosure relates to a texture morphing device. The texture morphing device includes: a plurality of supports arranged on a substrate to support a deformable mirror; an ITO layer; and a Distributed Bragg Reflector (DBR) layer. A pair of adjacent supports form a cavity with the ITO layer and the deformable mirror.

Patent number: 7078511Abstract: Two distinct scavenger receptor type proteins having high affinity for modified lipoproteins and other ligands have been isolated, characterized and cloned. HaSR-BI, an AcLDL and LDL binding scavenger receptor, which is distinct from the type I and type II macrophage scavenger receptors, has been isolated and characterized and DNA encoding the receptor cloned from a variant of Chinese Hamster Ovary Cells, designated Var-261. dSR-CI, a non-mammalian AcLDL binding scavenger receptor having high ligand affinity and broad specificity, was isolated from Drosophila melanogaster.
