Patent number: 6870184Abstract: A bipolar junction transistor (BJT) requires the fabrication of a BJT structure and of a support post which is adjacent to, but physically and electrically isolated from, the BJT structure. The BJT structure includes a semi-insulating substrate, a subcollector, a collector, a base, and an emitter. Metal contacts are formed on the subcollector and emitter to provide collector and emitter terminals. Contact to the structure's base is accomplished with a metal contact which extends from the top of the support post to the edge of the base nearest the support post. The contact bridges the physical and electrical separation between the support post and the base and provides a base terminal for the device. The base contact need extend over the edge of the base by no more than the transfer length associated with the fabrication process. This results in the smaller base contact area over the collector than would otherwise be necessary, and a consequent reduction in base-collector capacitance.Type: GrantFiled: July 30, 2003Date of Patent: March 22, 2005Assignee: Innovative Technology Licensing, LLCInventors: James Chingwei Li, Richard L. Pierson, Jr., Berinder P. S. Brar, John A. Higgins

Patent number: 6863999Abstract: Monazites and xenotimes are rare-earth phosphates showing a combination of properties expected to be suitable for thermal barrier coatings. For example, lanthanum phosphate (La-monazite) can be used to form thermal barrier coatings to protect superalloy and ceramic parts exposed to high temperature and damage by sulfur, vanadium, phosphorus and other contaminants. The monazite or xenotime coatings can be applied using any of the common application methods including EB-PVD, laser ablation and plasma spraying. The stoichiometry of the coatings can be modulated according to the stoichiometry of specially prepared starting target (source) material. The most effective coatings appear to be largely crystalline and show a columnar structure with feather-like microstructure. For La-monazite, effective coatings between 10 and 500 micrometers in thickness can be deposited on substrates having temperatures between about 750° C. and about 950° C.Type: GrantFiled: January 23, 2002Date of Patent: March 8, 2005Assignee: Innovative Technology Licensing, LLCInventors: Olivier H.

Patent number: 6858887Abstract: A BJT device configuration includes an emitter finger and via arrangement which reduces emitter finger width, and is particularly suitable for use with compound semiconductor-based devices. Each emitter finger includes a cross-shaped metal contact which provides an emitter contact; each contact comprises two perpendicular arms which intersect at a central area. A via through an interlevel dielectric layer provides access to the emitter contact; the via is square-shaped, centered over the center point of the central area, and oriented at a 45° angle to the arms. This allows the via size to be equal to or greater than the minimum process dimension, while allowing the width of the emitter finger to be as narrow as possible with the alignment tolerances still being met.Type: GrantFiled: July 30, 2003Date of Patent: February 22, 2005Assignee: Innovative Technology Licensing LLCInventors: James Chingwei Li, Richard L.

Publication number: 20040252209Abstract: A digital programmable gain stage for adjusting the gain of an input signal. A fine gain adjustment circuit sets gains between 1 and 2 (0-6 dB). A coarse gain adjustment stage adjusts the gain by multiples of 2. An input signal is multiplied by the fine gain adjustment factor, and then the coarse gain adjustment stage multiplies or divides the result by a multiple of 2. This architecture allows for gain adjustments from −24 dB to +66 dB in steps of 0.006 dB, using 14 bit resolution. Any number of gain ranges and gain resolutions are feasible with the current design by changing the bit width of the individual components.Type: ApplicationFiled: June 11, 2003Publication date: December 16, 2004Applicant: Innovative Technology Licensing,LLCInventor: Markus Loose

Publication number: 20040164626Abstract: A dynamic magnet system, particularly useful for electrical generation, employs multiple magnets in polar opposition to each other for individual movement relative to a support structure. The magnets have a critical angle of displacement from a horizontal static position of less than 1 degree, with at least some of the magnets having mutually different properties. With different magnetic strengths, a greater movement is produced for both magnets in response to movements of the support structure, for particular ranges of magnetic strength ratios, than would be the case with equal magnets. The magnet movement can be translated into an electrical signal to power an operating system. Ultra low friction ferrofluid bearings can be used to establish static coefficients of friction between the magnets and support structure less than 0.02, enabling useful power generation from only slight movements of the support structure.Type: ApplicationFiled: February 19, 2004Publication date: August 26, 2004Applicant: INNOVATIVE TECHNOLOGY LICENSING, LLCInventors: Jeffrey T.

Patent number: 6756866Abstract: A waveguide is disclosed that shifts the phase of the signal passing through it. In one embodiment, the waveguide has an impedance structure on its walls that resonates at a frequency lower than the frequency of the signal passing through the waveguide. This causes the structure to present a capacitive impedance to the signal, increasing its propagation constant and shifting its phase. Another embodiment of the new waveguide has impedance structures on its wall that are voltage controlled to change the frequency at which the impedance structures resonate. The range of frequencies at which the structure can resonate is below the frequency of the signal passing through the waveguide. This allows the waveguide cause a adjust the shift in the phase of its signal. An amplifier array can be included in the waveguides to amplify the signal. A module can be constructed of the new waveguides and placed in the path of a millimeter beam.Type: GrantFiled: September 29, 2000Date of Patent: June 29, 2004Assignee: Innovative Technology Licensing, LLCInventor: John A.

Publication number: 20040118973Abstract: The present invention provides a system and method for rapidly and precisely controlling vortex symmetry or asymmetry on aircraft forebodies to avoid yaw departure or provide supplemental lateral control beyond that available from the vertical tail surfaces with much less power, obtrusion, weight and mechanical complexity than current techniques. This is accomplished with a plasma discharge to manipulate the boundary layer and the angular locations of its separation points in cross flow planes to control the symmetry or asymmetry of the vortex pattern. Pressure data is fed to a PID controller to calculate and drive voltage inputs to the plasma discharge elements, which provide the volumetric heating of the boundary layer on a time scale necessary to adapt to changing flight conditions and control the symmetry or asymmetry of the pressures and vortices.Type: ApplicationFiled: December 20, 2002Publication date: June 24, 2004Applicant: Innovative Technology Licensing, LLCInventors: Norman D.
