Patent number: 7217584Abstract: The present invention provides silicon based thin-film structures that can be used to form high frequency optical modulators. Devices of the invention are formed as layered structures that have a thin-film dielectric layer, such as silicon dioxide, sandwiched between silicon layers. The silicon layers have high free carrier mobility. In one aspect of the invention a single crystal silicon material is bonded to a thin-film dielectric material to form a silicon-insulator-silicon thin-film structure for an optical modulator.Type: GrantFiled: August 10, 2004Date of Patent: May 15, 2007Assignee: Honeywell International Inc.Inventors: Cheisan J.

Patent number: 7206693Abstract: At least one magnetic field sensing device and GPS receiver integrated in a discrete, single-chip package, and a method of manufacture for the same. Rather than requiring at least two separate chips to be used to realize GPS positioning and compassing capabilities in a single device, an integrated, single chip solution can be used. A single chip integration of a GPS receiver and at least one magnetic field sensing device can reduce the physical space required to provide positioning and electronic compassing capabilities in a single device, and therefore allow such devices to be smaller, lighter, and possibly more portable.Type: GrantFiled: January 8, 2004Date of Patent: April 17, 2007Assignee: Honeywell International Inc.Inventors: William F. Witcraft, Hong Wan, Cheisan J. Yue, Tamara K. Bratland

A gate oxide is provided over each of the P? wells, and a gate silicon is provided over each of the gate oxides. The potential across the gate silicons and the N+ regions controls the capacitance of the varactor.Type: GrantFiled: January 7, 2002Date of Patent: January 30, 2007Assignee: Honeywell International Inc.Inventors: Cheisan J. Yue, Mohammed A. Fathimulla, Eric E. Vogt, William L. Larson

Publication number: 20040060164Abstract: At high frequencies, signal losses may occur in circuit designs employing magnetic isolators. Eddy current losses in the magnetic isolator substrate material are at least partially responsible for this signal loss. As the Eddy current losses may depend on the properties of the substrate, the type of substrate chosen for fabricating a magnetic isolator may be critical for reducing these losses. By fabricating the magnetic isolator on a high performance substrate, the Eddy current losses are reduced and the magnetic isolator provides better output signals at high frequencies.Type: ApplicationFiled: September 26, 2002Publication date: April 1, 2004Applicant: Honeywell International Inc.Inventors: Hong Wan, Cheisan J.
