Patent number: 7592144Abstract: The invention relates to fusion proteins and bacteria encoding them. The fusion proteins include a ligand-binding domain interposed between the splicing domains of an intein. An auxotroph-relieving protein domain is fused to one of the splicing domains so that the auxotroph-relieving function of the domain is activated upon ligand binding. The fusion proteins can be expressed in bacterial cells and used as sensors of binding of compounds with the ligand-binding domain of proteins such as the human estrogen receptors or the human thyroid hormone receptor. The bacterially expressed fusion proteins can detect and report agonist and antagonist activity characteristic of the naturally-occurring hormone with the ability to modulate the function of the protein from which the ligand-binding domain of the fusion protein is derived.Type: GrantFiled: March 17, 2005Date of Patent: September 22, 2009Assignee: The Trustees of Princeton UniversityInventors: David W.

Patent number: 7592191Abstract: A field emission backplate formed by laser crystallizing of an area of amorphous semiconductor based material. Emitter sites result from the rough surface texture caused by the crystallization process. The crystallization may be localized using laser interferometry, and profiled emitter tips grown on the localized crystalline areas. Such backplates can be used in field emission devices emitting into either a vacuum or a wide band gap light-emitting polymer. Furthermore, a backplate having self-aligned gates can be formed by depositing an insulator layer and a metal layer over the emitter tips, removing the top of the metal layer and etching away the insulator, leaving each tip surrounded by a metal rim. A planarizing agent can be used to refine this process.Type: GrantFiled: February 6, 2004Date of Patent: September 22, 2009Assignee: The University Court of the University of DundeeInventors: Mervyn John Rose, Ravi Silva, John Shannon

Patent number: 7591094Abstract: The light emitting surface of an image display light box is formed of multi-layer optical film having a reflectance greater than 95% and preferably about 99% or greater. This more efficiently utilizes light rays emitted by the light box's internal light source, since the multi-layer optical film reflects the light rays many times before the rays are absorbed and lost. Consequently, the light emitting surface can have a light transmissivity characteristic which is macroscopically invariant as a function of position on the light emitting surface. Light boxes utilizing prior art reflective materials require cumbersome, time-consuming, iterative trial and error techniques which must be customized for each light box in order to compensate for light absorption losses by imparting a variable transmissivity characteristic to the reflective material.Type: GrantFiled: May 31, 2005Date of Patent: September 22, 2009Assignee: The University of British ColumbiaInventor: Lorne A. Whitehead

Patent number: 7593531Abstract: A digital communication system based on the use of chaotic carriers is disclosed. For each symbol to be sent, the transmitter sends a reference chaotic signal followed by a transformed version of the reference chaotic signal. For different symbols, different transformations are performed. Also, the transformations are designed such that the transformed versions of the reference chaotic signal do not resemble the original reference chaotic signal. As a consequence, little information can be deduced by inspecting the frequency spectrum of the transmitted signal. Moreover, even if the communication could be detected, it is difficult to decode the messages because there are numerous transformations possible.Type: GrantFiled: May 7, 2004Date of Patent: September 22, 2009Assignee: The Hong Kong Polytechnic UniversityInventors: Chung-Ming Lau, Chi-Kong Tse

Patent number: 7591996Abstract: Selective occlusion of a blood vessel is achieved by selectively damaging endothelial cells at a target location in the blood vessel, resulting in the formation of a fibrin clot proximate to the damaged endothelial cells. Additional fibrinogen can then be introduced into the blood vessel if occlusion is not achieved, as the fibrinogen is converted to fibrin by enzymes released by the exposed thrombogenic tissue and activated platelets. Endothelial cells are selectively damaged using thermal effects induced by ultrasound, by mechanical effects induced by ultrasound, or by mechanical effects produced by a tool introduced into the blood vessel (such as a catheter-based tool). A particularly preferred technique for selectively damaging endothelial cells involves introducing an ultrasound activatable agent into the blood vessel, and causing cavitation in that agent using pulses of high-intensity focused ultrasound having a duration insufficient to induce thermal damage in adjacent perivascular tissue.Type: GrantFiled: August 17, 2005Date of Patent: September 22, 2009Assignee: University of WashingtonInventors: Joo Ha Hwang, Andrew Brayman
